This is what the expert warnings say, when each El Niño impact comes due, and what can still be done to minimize the hunger and other impacts of the 2026-7 El Niño.

A Different Kind of Disaster

Most disasters arrive without permission. An earthquake gives no notice. A flash flood gives minutes of warning. A hurricane gives days.

The hunger now forming in the world’s food system is not like that. Its coming has been predictable for months, it will take another year for the 2026-7 El Niño to fully arrive, and the instruments watching it are free for all to read. It is a food crisis on a schedule where prevention is possible.

“The cruelest thing about the hunger from the 2026-7 El Niño now forecast is that IT IS FORECAST. Nobody in 2027 will be able to say the maps were unavailable or ‘How could I have known?’ The reports are free, public, and updated weekly. Humanitarian actions still can be taken to respond to the coming hunger, but will we act?”

That is the question this article asks. Everything else said in this article is evidence for why and how we should act, and the last section tells exactly what we still can do to anticipate and prevent the coming hunger.

The Warning System for Coming Hunger Already Exists

Start with what is being published right now, this week and every week, by people paid by taxpayers to publish it.

Figure 2. The core public monitoring systems for global food security. None of them requires a subscription, a login, or a security clearance.

The U.S. Drought Monitor releases a map every Thursday morning showing where American drought sits and, crucially, a change map showing where drought has worsened over the previous week. Europe’s Drought Observatory does the same every ten days. NOAA monitors the temperature of the tropical Pacific continuously and publishes a monthly forecast of how strong this El Niño is going to be. Crop analysts in Washington and Brussels publish yield forecasts for every major growing region, every month. FEWS NET publishes which districts of which countries will run short of food, and roughly when.

None of this is obscure. All of it is written in plain language. Any journalist, aid official, member of Congress or member of the European Parliament can read the whole system in an afternoon.

This means the honest way to describe the hunger that is coming is not as a surprise, and not as a tragedy. It is a food crisis on a schedule.

But here is a warning: this system is not permanent. In September 2025 the U.S. Department of Agriculture announced it would stop publishing its annual Household Food Security report, the thirty-year record of how many Americans cannot reliably afford to eat. ¹ Ending the count does not end the hunger. It ends the ability to see it. Everything this article demonstrates about the value of public data applies with equal force to why we need to keep the U.S. Household Food Security Report as a public resource.

Why Hunger Arrives Late

Before we discuss the schedule itself, one idea has to be clear, because without it the rest looks like alarmism.

The single most misunderstood thing about food crises is timing. People expect a drought to produce hunger the way a fire produces smoke; immediately, visibly, in the same place and time.

It does not work that way, for a simple reason: the harvest a drought destroys is usually not the one you, people of the Global South or the rest of the world are currently eating.

A dry summer damages a crop that gets harvested in autumn, sold or stored over the winter, fed to livestock or put on the market in the spring, or sold to people through the spring and summer and shows up as the price of grain, meat and milk or grain a year later. A farmer who cannot afford fertilizer this season plants a weaker crop next season. A field left unsown in September is a shortfall the following August. Every link in that chain adds months to when hunger will arrive.

The gap between the weather and the hunger is not evidence that the warnings were wrong. It is the normal delay of a food system, and it is exactly the space of time during which something could be or could have been done. It is why there is time, between now and when the worst of El Niño hits, in which humanitarian assistance can be mobilized.

That delay is the reason for hope in this story. It is also the reason for urgency. The two are both caused by the same facts and knowledge.

Three Pressures, One Year

Three separate things are pressing on the world’s food supply at once this year. They are usually reported as unrelated stories, which is why the picture often looks confusing. Taken in order, they are straightforward and combine to form a clear picture.

Each of these three is set out in full in the following sections, with the sources. I highly suggest that you read the details of all three because the droughts, El Niño and the Fertilizer crisis are going to cause incredible suffering and none of them are what you think. What follows first is a summary of what the three of them together are already doing and are going to do to people around the world:

The Calendar

With the three pressures in view, the sequence becomes readable. Here is the schedule, as the public data currently describes it, it is beginning to happen as predicted and we have hard evidence that El Niño’s impacts on rains and crops have already started to occur.

June to August 2026 - already happened. The rains that feed Sudan’s sorghum and sesame did not arrive, and the Nile River fell with the lack of rain. The lack of rain will impact both rainfed and irrigated crops in Sudan and the region. This is the one row in the predicted schedule of El Niño’s rearrangement of rainfall that can already be checked against the world. It happened as forecast.

September 2026 - now. Farmers across northern Europe have about four weeks to plant this autumn’s oilseed crop. The window is set by daylight and by pests, not by frost, and it does not move. Planting needs rain at sowing and rain again each week for the four weeks thereafter. If this rain does not come, a crop that was meant to be a record becomes a shortfall, and that shortfall belongs to 2027, not to this year. Almost nobody is watching this. It may be the most consequential four weeks in the whole sequence. ² Oilseed matters more than its acreage suggests, because one crop feeds two markets. Crushed rapeseed yields roughly 40 percent oil and 60 percent meal. The oil goes into cooking oil and biodiesel, the meal is what European dairy herds and pig and poultry farms are fed.

A shortfall raises the supermarket oil prices and the feed bill at the same time. Vegetable oils also trade as a single pool. Palm, soy, rapeseed and sunflower make up 88 percent of all the cooking oils that the world eats. Commercial buyer substitute freely, so a European failure to produce rapeseed does not stay in Europe. The increase on global demand will arrive just as El Niño impacts next year’s palm oil production. Analysts estimate Indonesian and Malaysian output of palm oil could fall by some 4.5 million tonnes based on the historic pattern of where past El Niños have caused damage. The market has already banked the expected record European crop, causing rapeseed oil prices to ease over the summer on expectations of larger supplies in 2026/27. That assumption is what these four weeks decide. If the harvest is smaller than expected, vegetable oils tighten worldwide, and that matters more than the acreage suggests. Vegetable oils supply about a tenth of the world’s daily calories, second only to cereals, and they are the cheapest dense calorie a poor household can buy, it is the item a wealthy shopper substitutes with something else and the one that a poor one simply goes without.

There is a lever here. Around 31 million tonnes of vegetable oil is burned in the EU as biodiesel each year, the calories from this oil are enough to feed more than 320 million people. A large share of Europe’s rapeseed oil goes to biofuel rather than food. If the crop comes in short, Europe faces a choice: relax the EU Biofuel Mandate and release those calories for food, or import and outbid poorer buyers from around the world to drive up food prices and make EU biofuels. This is the article’s argument in miniature. ² Whether a bad rapeseed harvest results in hunger depends on a decision by the EU.

October 2026 to February 2027 - the feed bills. Grain harvested this autumn becomes animal feed this winter. Feed is the largest single cost in producing meat, milk and eggs. This is the first stage that ordinary shoppers in wealthy countries actually notice, and they notice it at the meat counter rather than in the bread aisle.

December 2026 to February 2027 - the ocean peaks. The El Niño reaches its forecast maximum. Southern Africa plants its single annual maize crop in December, directly into the forecast peak of when El Niño is expected to cause droughts.

January to March 2027 - the lean season. Southern Africa’s hungry months. This is the first point in the whole sequence where hunger stops being a projection and becomes a measurement, hungry mouth by hungry mouth. By then, every decision that could have softened the hunger will already have been made or not made. We do not have much time.

Spring to autumn 2027 - the price wave in rich countries. European food inflation is expected to peak near 3 percent, roughly a percentage point of which is attributable to this year’s weather. ³ In the United States, the same global prices arrive on top of drought and input-cost inflation, and tariffs already in the system.

Summer 2027 - a new American drought. The snowpack that fails to accumulate in the Northwest this winter becomes the water that is not there next summer. This is a region that in a good year grows and exports a great deal of wheat but will have a reduced harvest due to the expected drought.

Late 2027 - Sudan’s shortfall arrives. The harvest now failing will be eaten first and missed later. FEWS NET expects conditions to ease around the November harvest, and the reduced food stocks due to the El Niño will be felt in the second half of 2027.

2028 - the slow damage. The phosphate skipped in 2026 starts to show up as a lower yields and smaller crops, in the countries least able to absorb a reduced harvest.

Where These Three Crop Drivers Actually Land

One distinction matters more than any number in this article.

In Europe and America, the crops lost due to drought are called inflation. In Nairobi, Khartoum and Port-au-Prince, the same crop loss is measured in missed meals and increasing hunger.

A European household spends roughly a tenth of its income on food. A three percent food-price rise there is an irritation, a slightly worse year, an argument about supermarket margins. In countries where food takes up to forty percent of household income, an identical price move is a family dropping from two meals a day to one.

That is why the hunger from this convergence of factors will not land where the droughts happened. Europe will eat. America will eat. Both will complain about grocery bills, and both complaints will be legitimate, particularly for the families in those countries who were already struggling. Nearly one in four American adults reported living in a food-insecure household in 2025, and more than one in four of working age. ⁴ Massachusetts, counted by household rather than by adult, is worse still: a record 40 percent, roughly 1.1 million households, reported food insecurity in 2025, more than double the 2019 rate. ⁵

But the acute hunger will land in Sudan, which imports roughly four fifths of its wheat and already has more than nineteen million people short of food. It will land in southern Africa, where a single failed maize season has no backup. It will land in Haiti, Somalia, Chad and South Sudan, which sit at the top of the humanitarian warning lists precisely because they have no food cushion left. ⁶

In Sudan it is no longer a forecast. The rains that should have come in June and July did not come, and the Nile River has fallen due to the missed rains. The reservoir behind Ethiopia’s Grand Renaissance Dam stood six meters lower this July than last, and parts of the Blue Nile basin have had as little as half their normal rainfall. In Gedaref, where most of the country’s sorghum and sesame is grown, fields that are ordinarily green by August were still brown this month, and farmers gathered behind their imams to pray for rain. The agriculture ministry is telling farmers to switch to drought-resistant varieties and to delay planting. Those who can still plant say it costs four times what it did last year, because the same closure of the Strait of Hormuz that raised fertilizer prices in Iowa raised them in Gedaref. On a farm his family has held for a century in Al-Jazira, which he recovered from the Rapid Support Forces only last year, a farmer told reporters that he is sixty-three and has never seen the Nile River this low in August. ⁶

The Nile River running low and the reservoir depleted were foreseeable too. Elfatih Eltahir at MIT has spent thirty years documenting the link between El Niño and the flow of the Nile, and his work shows that when an El Niño event begins in late spring, as this one did, the probability of drought across southeastern Sudan and northwestern Ethiopia is high. The warning for Sudan existed before the rains failed. Nor is Sudan alone in having crossed from projection into measurement.

In the week of August 20, 2026, the U.S. Climate Prediction Center upgraded southern South Sudan and parts of northern, eastern and central Ethiopia to drought after ninety days of severe rainfall deficits. Recorded dryness due to lack of rain is worsening across Central America and Venezuela. In the Dry Corridor of Guatemala, Honduras and El Salvador that dryness has already become hunger. Much of this region saw only five to eight days of rain between late June and late July. Honduras has lost close to nine thousand hectares of maize and three thousand hectares of beans. The FEWS NET now places the poorest households of Guatemala’s Dry Corridor in Crisis through September. Southern Africa is the exception that proves the schedule: its rains are not due until October, so it is still, for now, a projection. ⁶

The World Food Programme estimates that a total of 49 million people will be pushed into acute hunger by this El Niño. They would be added to the 266 million people almost half of which are children, across 47 countries who were already in acute hunger in 2025. That is a figure that has roughly doubled in a decade, and which includes 39 million in Emergency conditions and 1.4 million in Catastrophe (famine), the phase in which people starve. The WFP has anticipatory plans running in more than fifty countries. It published that estimate this month, which is to say that the number of people this event will make hungry is itself already a matter of public record. ⁶

Whether more people enter famine is not really a forecasting question either. The IPC already projects Sudan’s Catastrophe (Famine) population rising from roughly 135,000 in the spring to 200,000 across fifteen areas by the September lean season, and a risk of Famine is formally identified in fourteen areas of Darfur and South Kordofan through September, persisting in thirteen into January. Four other places also carry that risk this year: Sudan, South Sudan, Gaza and Somalia. Every one of those analyses says the outcome turns on conflict intensity and humanitarian access. On decisions, in other words, and not on rainfall. ⁶

“Again, none of those countries closed a shipping strait, warmed the Pacific, or dried out the Loire valley, nor did they make the decisions to cut the El Niño preparation networks.”

What We Already Know How To Do

Here is the part of this story that should be reported far more often than it is: we know how to prevent El Niño from turning into a humanitarian crisis. Not in theory. In practice, with methods that have been tested and costed. Unfortunately, the systems needed to do this have been dismantled since 2025 by cuts to U.S., European and Japanese foreign aid.

El Niño is the most predictable large-scale climate shock on Earth. It has been monitored for 150 years and the way that rains will be redistributed is well known. That predictability was turned into machinery after the 2015–16 event, which the UN itself judged to have been responded to too late. The decade since was spent building trigger systems: creating agreements that release money and supplies automatically when a forecast crosses a threshold, rather than waiting for a famine to be declared. In 2023–24 those systems reached three million people ahead of impact. ⁷ They work. They were simply too small in the past, but now a wrecking ball is being taken to them. They need to be rebuilt and quickly.

Because this is a schedule of changing rains and predictable hunger crises rather than a surprise, the responses can be unusually concrete and focused. It is a policy choice what we do and whether we prevent the impending crisis.

Fund the response before the failure. Cash, seed and pre-positioned food released on a forecast, rather than on a famine declaration, cost a fraction of late emergency aid and save lives that late aid cannot. The UN’s food agencies have asked for $202 million to protect nearly nine million people across 22 countries, explicitly ahead of impact of the coming super El Niño. The U.N. agencies say they are already positioned to act for 1.2 million of the people at risk, and that an additional $167 million would extend coverage to the remaining 7.6 million people. ⁸ Southern Africa plants in December. That money and aid has to move before then, into a humanitarian system whose largest donor, the U.S., cut its funding from roughly $14 billion to $3.7 billion in a single year, 2025. We need to restore those cuts.

Keep the grain moving. The lesson of the 2007–08 food crisis is that export bans spread from country to country, and that hoarding, not harvest failure, is what turns a shortage into a famine. Governments built shared systems to see real global stocks precisely so they could resist that panic. Using them, and pressing exporters early and publicly against blanket bans, will do more for the world’s poor in 2027 than any single shipment of aid.

Protect the households in America and Europe at the end of the chain. The price wave reaches American and European shops in 2027, on top of inflation, fuel and fertilizer price increases, and tariffs already in the pipeline. Cutting food assistance to America’s poor and working classes in the same window, kicking poor and working families off SNAP, is not a neutral budget decision, it is going to create suffering across America. The 2025 reconciliation law cut SNAP by roughly $187 billion over ten years, extended work requirements to adults aged 55 to 64 and to parents of children aged 14 and over, and for the first time in the program’s sixty-year history required states to share its costs. ⁹ That is a choice about who absorbs the cost of a Pacific Ocean weather and climate event they had no part in causing.

“Not one of these three actions requires a scientific breakthrough, a new institution, or a treaty. Each requires a decision, taken this autumn, by people who already have the information they need to prevent the impending crisis.”

The Point is: Famines and Massive Acute Hunger Aren’t Predetermined. They Still Can Be Prevented If You Act.

There is a version of the next eighteen months in which the warnings were missing, the science was contested, and the failures were genuinely unforeseeable. That version would be a tragedy, and no one would be to blame.

That is not the version we are in.

We are in the version where the maps are published every Thursday, the ocean is measured every day, the crop forecasts arrive every month, and every one of them is free. The hunger of 2027 will be the most thoroughly forecast hunger in all of human history.

Which means that every hunger crisis this El Niño produces will not be an accident of weather. It will be a decision, made in the autumn of 2026, by people and politicians who had the maps and the reports in front of them and should have known the consequences.

But a decision is not a fate determined. The same forecast that makes this hunger foreseeable is what makes it preventable, and that is the more important half of the sentence. The seed can be moved before the planting. The money can be released on the forecast rather than on the funeral. The grain can be kept moving. Every one of those things has been done before, and every one of them worked.

You can be one of the people who makes the politicians and policymakers look and listen, and who makes sure they know what to do to prevent these impending disasters.

Call your elected officials, state and federal, this week, next week and the week after that.

Ask simple questions:

1) have you mobilized the money needed for the 2027 El Niño lean seasons and hunger?

2) will it move before December when southern Africa plants?

Send them a copy of this article so you can be sure that they know that they have to act.

Only action by you and all of the people around you will prevent foreseeable famines from killing tens of thousands of innocent men, women and children in countries around the world far from the causes of climate change and the hunger that is accompanying this El Niño.

1. The Droughts That Are Already Here

Europe has just come through a summer in which half the continent was in some level of drought, much of Europe in severe drought, and the Rhine, the Loire, the Po and the Danube all fell to record lows. Across the Atlantic, the American drought peaked in March and April at the highest level for that time of year in the whole modern record, then eased somewhat while shifting to impact crops in the Plains.

Figure 3: The important thing about the European half is not how dry Europe was. It is WHY there is drought in Europe.

The drought that hit Europe this summer did not happen because the rain failed. Rainfall across western Europe was close to normal. What changed is that a hotter atmosphere caused by climate change pulls far more water out of the soil than it used to, so the same amount of rain no longer produces the same amount of water for crops to use and to create streams and rivers. Scientists examining the event found that the drying that caused Europe’s drought has become roughly eighty times more likely than in the slightly cooler climate without climate change. ¹⁰

Put plainly: the weather and rain did not have to get much worse for the crop losses to get much more severe. The available water moved. That is why this is a climate story and not just a bad summer weather story, and it is why the same pattern is likely to repeat and get worse as the world continues to warm.

Neither Drought Ends This Year

It would be reasonable to assume that a wet El Niño autumn where El Niño increases rain closes the drought chapter in parts of Europe and America. It does not, and the reasons differ on each continent.

In Europe, the thing driving the drought is not going away, because it is not the weather, it is not reduced rain. Rainfall varies year to year. The thirst of a warming atmosphere only goes in one direction. The same scientists who studied this summer, project that with a further 1.4°C of warming, drying conditions from an atmosphere demanding more evaporation will become roughly ten times more likely again in western Europe, and the odds of a soil-moisture deficit like this year’s will double. ¹¹

The most counterintuitive result happens in eastern Europe. The models there project more rain, not less in the coming years, enough that a year as dry as this last one would become only about a third as likely. Yet drought risk still rises. Warmer air pulls water out of soil and plants faster than the additional rainfall that is expected can replace it, so the ground dries out even as the skies get wetter. This is expected to continue and get worse as the world warms. More rain, more drought.

Figure 4. The water budget behind the paradox. Rain is only the income side of the ledger. When a warmer atmosphere raises the withdrawal faster than the deposit grows, the balance in the soil falls even in a wetter year. ¹² ¹³

“Climate change creates warmer air and increased evaporative demand, pulling water out of soil and plants faster than the expected additional rainfall can replace that water, so the ground dries out even as the skies and atmosphere get wetter. More rain, more drought.”

The reason that matters is a question of buffers. More rain sounds like reprieve, and where there is irrigation, it partly is. But eastern European farming is overwhelmingly rainfed. No canals, no allocations, no reservoirs sit between the atmosphere’s demand and the crop, so when evaporative demand outruns the rain, it comes straight out of the soil this year’s crop is rooted in. The same physics operates across the American West, this is not a European affliction, but there it meets infrastructure first, reservoirs, aquifers, rivers that have been dived for decades. As a result, a soil-moisture problem becomes a water-rights problem, which buys years of argument and some genuine protection. Eastern Europe has no such intermediary. The statistic arrives as a diminished harvest; in the same season the drought is measured.

This is not one study’s quirk. Research across Europe has found that the meteorological droughts themselves are getting shorter, while high evaporative demand stretches the total damage out longer, so that warm-season droughts and “flash droughts” are steadily replacing other kinds of drought. ¹² European river basins now lose 20 to 40 percent more water than their rainfall shortfalls alone would predict, because so much more water evaporates on the way into and down the rivers. ¹³

On the good side, long-term well records across Portugal, Spain, France and Italy show that water levels in wells are broadly stable, with one in five rising, showing better management has helped several semi-arid regions recover. ¹⁴ Europe’s groundwater is not uniformly collapsing. Europe’s soils and growing seasons are where the damage from increased evaporation is concentrated, and where crops are being decimated. Where people have managed water deliberately, the water has responded. That is worth holding onto and expanding.

In America, the drought will not end so much as relocate. That is a statement about geography, not about severity. Roughly two fifths of the country was in drought this August, and Lake Mead fell to a record low on the sixth of August 2026. ¹⁵ The same thirsty atmosphere is at work in America as in Europe; what moves is where this evaporative demand lands. The El Niño now building is forecast to push storms into the southern and southwestern United States and starve the northern tier, with below-normal precipitation and increased evaporative demand over the Northwest and north-central states set against a wetter southern tier. ¹⁶ For the Southern Plains, after eight years of drought, that is real relief.

But look at where the dryness is being sent. In Idaho, Oregon and Washington, a warmer El Niño winter means less precipitation overall and more of it falling as rain instead of snow, which means less snowpack, less summer runoff, and higher drought and wildfire risk the following summer. ¹⁷ Snowpack is a buffer of exactly the kind eastern Europe has never had: a reservoir that fills in winter and lets go slowly through the dry months. A warm winter does not drain it. It stops the snowpack from forming. That is a 2027 drought being manufactured this winter, aimed at the spring wheat country and the Pacific Northwest grain export belt, which are already among the driest parts of the country. Federal drought scientists caution that one wet winter will not refill the Southwest’s depleted reservoirs and aquifers regardless of how wet the El Niño makes it. ¹⁸

So, the honest summary is not that these droughts end in 2027. It is that the atmosphere gets thirstier on both continents and droughts continue, and what differs is only what stands in the way. Europe’s fields have nothing. America has snowpack and reservoirs, and this winter is forecast to take some of both, moving the shortfall north onto different farmers. Neither continent can expect a drought-free year 2027.

2. The El Niño in the Pacific Ocean That Is Still Coming

The second pressure has not arrived yet, and it is the largest.

A very strong El Niño is now forecast for this winter, with better than nine-in-ten odds, and a real chance of being the strongest event measured since records began in 1950. ¹⁹ El Niño is not a storm. It is a large-scale rearrangement of where rain falls on Earth, and it moves rain away from croplands in southern Africa, Southeast Asia and Central America, in a pattern that has repeated for a century and a half.

Figure 5. Pacific sea-surface temperature anomalies. NASA Worldview.

It deserves saying that this rearrangement is not all bad news. El Niño may actually help some of the places currently in drought. Forecasts suggest Western and Southern Europe turn wetter this autumn, and that the American Southwest and Southern Plains get an unusually wet winter. After years of drought in both regions, that would be a genuine mercy, and some farmers will end up owing this El Niño a debt.

But three things are true at the same time. Rain in October does not restore a crop harvested in September. The relief is forecast for the wrong regions on the wrong schedule: wetter in the Mediterranean, drier over exactly the northern European grain belt now deciding what to plant. Heavy rain arriving on hillsides burned bare this summer produces floods, not recovery.

The relief is real, regional, and late. It arrives for some farmers after the crop it might have saved is already in the trash, and it arrives in the same season the tropics, which already have had too little rain to grow their crops, have to plant their single corn crop of the year. The bottom line is that the 2026-7 El Niño is going to be severe and cause crop losses where there are the smallest buffers to prevent hunger and even starvation. We know where this is going to happen, where crops are going to fail, where people will be hungry.

3. The Fertilizer Squeeze

The third pressure is quieter and slower. Fertilizer costs spiked earlier this year after the closure of the Strait of Hormuz. Nitrogen prices have since fallen back substantially, and that part of the crisis has genuinely eased. ²⁰

However, the phosphate shortage which was also caused by the closure of the Strait of Hormuz hasn’t eased. The closure lifted the price of both nitrogen and phosphate fertilizers, but only the price of nitrogen (urea fertilizer) has come back down, because the two fertilizers are produced differently.

Nitrogen is manufactured: urea is made from natural gas, so when the energy shock passed the price of urea followed it down, and new capacity to manufacture urea can be built anywhere the gas is cheap.

However, phosphate is mined, in only a handful of countries that hold most of the world’s phosphate-rich rock, and two of them have stopped selling phosphate. China, the largest exporter, suspended phosphate exports in December to protect its own spring planting and has extended that suspension at least through August; traders do not expect phosphate shipments from China to resume quickly. Russia, another of the five countries that dominate the trade, has capped total fertilizer exports at 20 million tonnes from June to November, including some 7 million tonnes of the compound fertilizers that carry phosphate. Between them they have taken a large share of globally traded phosphate supply off the market, and there is nobody positioned to replace this shortage. Morocco and Saudi Arabia are already running flat out, and no significant new capacity is expected before 2027. ²¹

Then there is the acid. Turning rock into phosphate fertilizer takes sulfuric acid, and sulfur is not mined to order. It is stripped out of crude oil and sour gas during processing. This means how much of sulfur exists depends on how much oil and natural gas the world is refining, and where. The Gulf is traditionally one of the largest sources of sulfur production, which is why the same war that closed the Strait of Hormuz also tightened the world supply of sulfur, since these countries have not been processing typical amounts of oil and sour gas since exports are restricted. China also has restricted exports of sulfuric acid alongside the restriction on the export of phosphate fertilizer itself.

Ammonia and urea supplies on the global market have rebounded since the spring, as shipping fears receded and China loosened a separate restriction on the export of urea. The global sulfur supply has not similarly rebounded. The price of sulfur went from $155 a tonne to $400 a tonne between late February and early May 2025. A plant with its own phosphate rich rock and its own manufacturing facility still cannot make phosphate fertilizer without sulfuric acid. That is not hypothetical. In May, the company Mosaic which mines most of America’s phosphate rock and makes most of its phosphate fertilizer, halved output at its plants in Bartow, Florida and Faustina, Louisiana and scaled back further production in Brazil, explicitly to avoid buying sulfur at the high prices being asked due to the closure of the Strait of Hormuz. By July it was reducing two more American plants as its sulfur inventories fell and prices remained high. The largest phosphate producer in America is switching capacity off in the middle of a phosphate fertilizer shortage, because the sulfuric acid needed to produce it is too expensive for Mosaic to make any profit on the production of phosphate fertilizer. Washington has acknowledged the squeeze in the plainest terms available to it. On 29 June, 2026, the President signed a proclamation declaring an emergency over threats to the availability of phosphate fertilizer, and suspended anti-dumping and countervailing duties on Moroccan phosphate for up to eight months, citing conflicts in fertilizer-producing regions and trade actions by major producing countries. ²¹

So, the price of phosphate fertilizer stays high, and farmers around the world put less of it on their fields. ²¹ Crops feed on the reserve of phosphate built up in the soil over past seasons, not on what was spread this spring. As a result, a farmer who skips an application of phosphate fertilizer this year because of the high prices sees no penalty at this year’s harvest, because the crop draws down its nutrient savings from the soil instead. The penalty for not applying phosphate because it is too expensive this year arrives in the reduced crop production in the next two to four years. The reduced productivity of the fields arrives first for the farmers whose small crops and limited resources forced them to skip applying phosphate in the first place. ²¹ The failure to be able to afford applying phosphate causes hunger for years to come after the phosphate fertilizer is not applied to fields.

Figure 6. Why the phosphate bill arrives late. The crop draws on a reserve accumulated over past seasons, so the harvest immediately after a skipped application looks normal. The reserve, not the yield, absorbs the loss first. ²¹

Three pressures, then: a drought whose cause is strengthening as climate change becomes more severe, a Pacific Ocean pattern that peaks this winter, and a nutrient input squeeze that plays out slowly over years. Now is the time to take preventative action and for you to reach out to your federal and state lawmakers and push them to prevent a lean rain year from turning into a humanitarian disaster.

On the wider oilseed complex: IFPRI puts vegetable oils at roughly 10 percent of daily caloric food supply, about 300 kcal per person per day, second only to cereals, and notes they are an essential cooking item particularly for poor consumers unable to shift to butter or animal fats; the same analysis puts the 31 million tonnes of vegetable oil converted to biodiesel globally at a calorie equivalent of feeding more than 320 million people a year. FAO projected that 44 of every 100 additional calories in developing countries to 2030 would come from vegetable oils. Palm, soybean, rapeseed and sunflower account for about 88 percent of global edible oil consumption, with palm alone some 46 percent of traded volume and Indonesia and Malaysia supplying 88 percent of that; Marex estimated Indonesian and Malaysian output could fall by about 4.53 million tonnes on the pattern of past strong El Niño years. FAO’s vegetable oil price index reached a four-year high in July 2026 even as rapeseed and sunflower oil quotations eased on expectations of larger 2026/27 supplies.

More than 10,000 adults participated. Note that this is not the same measure as the discontinued USDA series: the WBNS uses the six-item short form of the Household Food Security Survey Module and reports the share of adults, where USDA used the eighteen-item module and reported the share of households, last putting it at 13.7 percent, or 47.9 million people, in 2024. The two figures are not interchangeable, and the Urban Institute presents its survey partly as a substitute for the federal data that is no longer collected.

On the existing caseload: Global Report on Food Crises 2026, published 24 April 2026 by the Global Network Against Food Crises, estimating 266 million people in 47 countries and territories at IPC/CH Phase 3 or above in 2025, or 22.9 percent of the analysed population, up from 22.3 percent in 2024. More than 39 million were in Phase 4 (Emergency) and 1.4 million in Phase 5 (Catastrophe) across Haiti, Mali, the Gaza Strip, South Sudan, Sudan and Yemen, a ninefold rise in the Phase 5 population since 2016. Famine was confirmed in parts of Gaza and Sudan. The 2024 comparison covered 53 countries and 296 million people, so the year-on-year fall in the absolute number reflects fewer countries analysed rather than improvement; the report notes the lowest data availability in a decade, attributed to funding cuts and restricted access.

The proclamation notes that farmers apply more than half their annual phosphate between autumn and early spring, and that domestic production cannot support demand. In February 2026 the administration had already invoked the Defense Production Act over domestic production of elemental phosphorus. On the supply side: China’s National Development and Reform Commission met producers on 11 December and suspended phosphate fertilizer exports in principle until August 2026 to secure domestic supply for spring planting, withdrawing an estimated 7 to 9 million tonnes, or roughly 30 percent of globally traded volume. Analysts noted that China’s sixty-day inspection and quarantine period could delay cargoes until October even once the suspension lapses. The World Bank notes that the Hormuz route carries a large share of global sulphur and ammonia shipments, both required to manufacture DAP fertilizer, or diammonium phosphate, and that Morocco’s OCP accelerated maintenance at its phosphate plants in response. The two inputs have since diverged: Middle East ammonia fell from about $680 to $560 per tonne across July 2026 and the July Tampa contract settled at $665, roughly $50 above pre-conflict levels, while sulphur remained exceptionally elevated and continued to carry cost through the phosphate chain. Russia’s restriction is separate and concurrent: a government decree set an export quota of 20 million tonnes of mineral fertilizer for 1 June to 30 November 2026, of which more than 8.7 million tonnes is nitrogen and upwards of 7 million tonnes compound fertilizer, extending quota arrangements in place since 2021 (Interfax; Tridge). Trade reporting describes licensing and quota regimes in both China and Russia as limiting spot availability of DAP and MAP fertilizer, Monoammonium Phosphate. Analysts note that Morocco and Saudi Arabia are already at capacity, with new phosphate production not expected before 2027–28. China has also restricted exports of sulphuric acid, the reagent used to convert phosphate rock into phosphoric acid. On Mosaic: the company announced curtailments on 11 May 2026, halving rates at Bartow and Faustina and scaling back in Brazil, and extended reductions to its Riverview and Uncle Sam plants in July as sulphur inventories fell (Argus Media; World Fertilizer; Glacier FarmMedia). Chief executive Bruce Bodine described the move as a temporary way to avoid buying incremental sulphur at prevailing prices. On the first-quarter call management put marginal sulphur near $1,200 a tonne against realised costs nearer $540, making some production uneconomic; the phosphate segment recorded a $48 million operating loss on a $280 million rise in raw material costs. Mosaic accounts for roughly 64 percent of US phosphate rock mined and about 80 percent of domestic phosphate fertilizer manufactured. Between 2018 and 2022, China, Morocco, the United States and Russia together accounted for close to 80 percent of world ammoniated phosphate production (IFPRI).

I am delighted to be joined by Tom Harris from Climate Uncovered Substack for this article. Tom is a climate advocate who is interested in letting the data do the talking and bringing complex scientific research papers to a wider audience. I highly recommend his Substack and hope you subscribe for more of his highly insightful and relevant content.

Physics sets the shock. Policy sets how many people go hungry. Slowly though food insecurity, chronically through lack of calories, and acutely through the starvation that kills. Every number and figure we cover below carries a source, and a confidence level wherever the source states one, because the impacts on global and domestic hunger in a 2°C world due to climate change does not need to be exaggerated, the truth is scary enough.

The 2ºC Dinner Table is Already Being Set

In 2025, for the first time in the history of the world’s hunger monitor, famine was confirmed in two countries in the same year. Parts of Gaza. Parts of Sudan, with four more countries on the brink of famine. Across six countries, 1.4 million people ended 2025 in the category the international humanitarian classification calls Catastrophe, the level at which starvation and death are no longer projected but counted body by body. That figure is nine times higher than it was a decade ago.

All of that happened at about 1.4°C of warming, in a world that still had a functioning humanitarian system.

Those figures measure acute hunger, the crisis level tracked by the Integrated Food Security Phase Classification, when a shock strips households of the last buffers between survival and starvation and famines are declared. This is different from chronic hunger, the persistent shortage of calories and nutrients that the UN Food and Agriculture Organization (FAO) estimates affect roughly 645 million people worldwide. It is also different from food insecurity, the broadest category, which captures people who have had to skip meals or go without food for a day or two. Because separate systems measure these three categories, they can move in different directions: chronic hunger can decline in the same year acute hunger rises. This article tracks all three and does not let the more reassuring number obscure the more dangerous one.

Figure 1. Global hunger at 2°C

The threshold this article discusses is what happens to hunger when the world crosses to 2°C above the historic (1850-1900) baseline, and the fact that this is no longer a problem of the 2050s. With the rate of warming now measured rather than modelled, 2°C could arrive as early as 2036. That is inside the working career of every official who will decide how to prepare for it, inside the term of most mortgages held by the people reading this, and before the high school graduation of a child about to start their education this autumn.

So, the question is not whether a hotter world makes more people hungry. That was answered in Somalia in 2022, where a drought that human warming made roughly a hundred times more likely killed an estimated 43,000 people, about half of them children under five. The question now is how many more, where, and whether anybody with the power to change the answer has the courage and the empathy to do something about it in the short time that remains.

The published answers are neither reassuring nor agreed. Estimates of how many additional people will go chronically hungry in a 2ºC world run from roughly one million to roughly 183 million.¹² That is not a scientific inaccuracy or a rounding disagreement. It is a spread of nearly two orders of magnitude, due to the single most important fact in this article. The choice of how many people will go hungry depends on the policy choices our leaders make right now.

A range that wide usually means the underlying science is immature. Here it means something else, and that difference matters more than any single number in this article. The models producing the low end and the high end broadly agree on the physics. They agree on how much heat a maize plant can tolerate during pollination, where rainfall belts are shifting, and what a hotter atmosphere does to evaporative demand. What they disagree about is what we and our leaders will do about it: whether trade stays open when exporters take fright of a food shortage, whether smallholders can access credit and improved seed, whether safety nets hold through the price spikes that are coming, and whether adaptation finance arrives before the shock or only in the wreckage, hunger and famine after it. Numbers of this size are easy to read as fate. They are not. For once the climate change story is not about ever-increasing suffering, at least it needn’t be.

2ºC sets the size of the shock. Policy choices decide how much of the shock becomes hunger.

These projections need a baseline. The FAO’s 2026 edition of The State of Food Security and Nutrition in the World puts the number of people facing chronic hunger at approximately 645 million in 2025.³ This article uses that as a level but does not treat the reported direction of where hunger is going as established.⁴

The Horizon: When 2ºC Arrives

The last IPCC assessment, AR6 published in 2023, working from evidence published up to 2019, indicated that under a moderate emissions pathway (SSP2-4.5) the 2°C threshold would not be breached for several decades, most likely in the 2050s. That estimate has aged badly, and it has aged badly for reasons of scientific measurements rather than politics.

The most compelling new evidence concerns the Earth’s Energy Imbalance (EEI): the difference between the solar energy arriving at the top of the atmosphere and the energy radiating back to space. It is the cleanest single indicator of whether the planet is accumulating heat, and how fast. NASA’s CERES satellite record now shows an approximately fourfold increase in the rate at which the Earth system is accumulating energy since 2003, and independent analysis finds the imbalance has more than doubled in recent decades.⁵ Observed accumulation is running above the projection for RCP8.5, the high-emissions scenario in the IPCC latest report, even though human emissions are following a lower path than the RCP8.5 pathway assumed. Warming is actually occurring faster than anticipated. Impacts are arriving decades earlier than hoped.

A large part of the explanation is a better understanding of cloud feedbacks. Earlier assessments could not determine whether clouds would amplify warming or restrain it; by AR6 the sign was clear, and it was amplification, though the uncertainty band remained wide. Work by James Hansen and colleagues indicates the feedback is strongly positive and is the primary driver of the rise in EEI: the planet is dimming, losing cloud cover while the clouds that remains have grown less reflective. On this analysis, the climate’s sensitivity to greenhouse gasses sits at the high end of the IPCC’s likely range.⁶

Since the EEI is a rate of accumulation, rather than a measure of the stock already accumulated, a rising EEI means that the energy available to warm the planet is itself accelerating. That acceleration is now visible in every downstream measure: surface air temperature, sea surface temperature, ice melt, sea level rise, ocean heat content, atmospheric relative humidity and the intensity of extreme weather events.

A 2026 analysis by Foster and Rahmstorf⁷ found that global temperature is accelerating even after accounting for natural variability, including the El Niño–Southern Oscillation. Their analysis places the crossing of the 1.5°C threshold between 2026 and 2028. Extrapolating the emerging warming rate puts the crossing of the 2°C threshold as early as 2036. That is approximately two decades earlier than the IPCC’s last estimate, and that temperature increase is now close to unavoidable.

Figure 2. Two estimates of when 2ºC arrives, and what changed between them.

The consequence is that everything downstream of the changes in climate arrive faster. But plant breeding programs take years to move a trait from the trial plot to the farmer’s field. Irrigation schemes, grain reserves and cold chains take even longer to finance and construct. Trade agreements take longer still. On the timeline the physical evidence now supports for increasing global temperatures, 2°C arrives with very little warning and very little room for us to prepare.

The Calories That Quietly Disappear

The most useful single number in the agricultural literature comes from Hultgren and colleagues (2025), an eight-year study of six staple crops across 12,658 regions, capturing two-thirds of global crop calories. For every degree of global warming, the world loses approximately 120 kilocalories per person per day, about 4.4% of daily consumption. Critically, that estimate is net of adaptation: it already assumes farmers change cultivars, shift planting dates and adjust management in response to the climate they experience, despite the fact that farmers notoriously resist changes to their farming practices.⁸ In the West this temperature change and reduction in crop production mostly arrives as higher grocery prices. In the Global South it arrives as food insecurity and acute hunger.

Figure 3. Global staple-calorie losses, and how much of them adaptation actually recovers.

The timeline matters as much as the magnitude. The same study, written before the energy-imbalance work by James Hansen and colleagues described above, puts the global calorie loss at roughly 7.4% by 2050 and 11.2% by 2100 under moderate emissions once adaptation is included, and 24% by 2100 on a high-emissions pathway. The 24% figure is the one the media picks up; the mid-century figure is the one that should be of immediate concern, especially as its timing is on the optimistic side. It sits inside the planning horizon of every finance ministry, development bank and grain trader now operating, and is far harder to dismiss as a future scenario.

Adaptation’s contribution can be stated precisely: adaptation and income growth together offset 23% of global losses in 2050, rising to about a third by 2100. That is real mitigation. But it is also a ceiling, and even with the adaptation fully implemented, it leaves the majority of the loss standing in a model already generous about how quickly temperatures will rise and farmers will adjust. The offset is also wildly uneven. In Africa it reduces projected end-of-century losses from 16.0 to 11.6%; in North America, from 21.0 to 20.8%, which is within rounding of nothing at all. The regions with the most agronomic capital have the least room left to improve, because they already farm close to the optimum.

The distributional result inside the same study is worth stating, because it cuts against the intuition that climate damage is a poor-country problem. Projected end-of-century crop yield losses average 41% in the wealthiest regions and 28% in the lowest-income regions. The steepest damage falls at both extremes of the agricultural economy: on modern breadbaskets currently enjoying the world’s best growing conditions, and on subsistence communities depending on small harvests of cassava and millet.

Behind the smooth averages sits a distinctly un-smooth implementation mechanism. Tropical staples such as maize, sorghum and rice are already grown close to their ceiling temperatures. Yield does not decline gently as the thermometer rises; it holds, and then collapses, because the damage is concentrated in a narrow reproductive window. Agronomists have measured the critical thresholds for seed set at flowering with unsettling precision: roughly 37.2°C for rice, 37.9°C for maize and just 27.3°C for wheat.⁹ Above that threshold during the flowering period leads to sterilized pollen and failed fertilization. Grain filling is also reduced, so even a handful of hot days can destroy a whole crop. In this context, averages hide the real hunger smallholders in the Global South and smaller farmers in the Global North will experience.

The nutrients that go missing too

There is a second loss inside the first, and it does not appear in tonnage of food harvested. Elevated atmospheric CO₂ makes staple plants grow more and nourish less. Wheat grown under the concentrations of CO₂ expected in the atmosphere later this century loses approximately 9.3% of its zinc, 6.3% of its protein and 5.1% of its iron. Up to 35% of the global population depend on these crops for the bulk of those nutrients.

Translated into people rather than percentages, the effect is huge. Smith and Myers (2018) estimate that elevated CO₂ could push an additional 175 million people into zinc deficiency and 122 million into protein deficiency, while 1.4 billion women of childbearing age and young children, precisely the groups for whom iron status matters most would lose more than 4% of their dietary iron, by 2050. The burden of these nutrient losses concentrates in some particular countries rather than being spread in India alone, the same analysis finds roughly 50 million people newly zinc-deficient, 38 million newly protein-deficient, and 502 million women and children in the iron-vulnerable group.

Figure 4. Nutrient dilution under elevated CO₂, and the populations it reaches.

The IPCC’s Sixth Assessment reaches compatible conclusions and assigns them high confidence: protein content in rice, wheat, barley and potatoes falls by 6–14%, placing an additional 150 million people at risk of protein deficiency; zinc dilution adds 150–220 million to the zinc-deficient population and worsens deficiency in more than a billion people who are already deficient.¹⁰

A harvest can arrive exactly on target and still carry less nourishment than the same harvest did twenty years ago. The one number everybody watches is the weight of grain harvested, but weight of grain does not say how nutritious it is.

The outcomes show up in clinics, rather than on commodity exchanges, as stunted growth, impaired immune function, complications in pregnancy, higher child mortality. Hidden hunger is a term of art, but the hiding is literal. The metric everyone watches is the weight of grain, and the weight of grain is the one thing that does not change, how nutritious the grain is, on the other hand, does.

A One-Percent Grain Shortfall Becomes a Six-Percent Price Shock

Between a lost calorie and a hungry person sits a market, and markets for staple foods are peculiar. Demand is highly inelastic: people do not respond to a bad harvest by eating less bread. Supply is equally unresponsive within a season, because when one crop fails another cannot be planted for immediate replacement. The entire adjustment therefore falls on price.

The elasticities estimated by Roberts and Schlenker give the standard result.¹¹ Their framework identifies demand using current-period yield shocks and supply using past shocks working through inventories and finds commodity demand to be extremely inelastic. A shortfall of roughly 1% in global caloric availability (a shortfall of corn, rice, wheat, sorghum or cassava) therefore produces a price movement several times larger, on the order of 6%; 2% crop reduction becomes roughly 12% price increase, 5% shortfall of grains becomes a 30% increase in price, and a 10% crop reduction becomes a 60% price increase⁸ (Some UK farmers are reporting a 20% drop in wheat yield this year due to the unprecedented 2026 drought and heat). Realized responses depend on stocks-to-use ratios, trade policy, export restrictions and speculative positioning, all of which can push the multiplier higher. This is not a market failure. It is what a well-functioning market does when neither supply nor demand can adjust. The impacts are real though.

Until recently this was a modelled claim. It is now an observed one. Kotz and colleagues (2025) document 16 cases across 18 countries between 2022 and 2024 in which extreme heat, drought or rainfall drove measurable food-price spikes, many following weather beyond all historical precedent prior to 2020.¹² Olive oil across the European Union rose by around 50%. Japanese rice rose by around 48%. U.S. vegetable producer prices rose about 80% after drought across California and Arizona. Cocoa rose roughly 280% after a February 2024 West African heatwave that attribution analysis found had been made approximately 4°C hotter by climate change.

Figure 5. Documented price responses to recent climate extremes, and the mechanism that produces them. EU olive oil rose around 50%, and US vegetable producer prices around 80% after drought in California and Arizona.

The persistence of the increase matters as much as the spike. Earlier work by Kotz and co-authors, a collaboration between the Potsdam Institute and the European Central Bank, found that higher temperatures and related crop shocks raise food and headline inflation persistently for roughly 12 months after the event.¹³ A single hot season is not a single bad month at the checkout. It is a year of elevated prices working through processing, retail and wage bargaining and landing on those least able to pay.

Then comes the political amplifier. Faced with domestic price pressure, exporting governments often restrict exports. Each restriction is locally rational and globally destructive: it removes supply from the world market at precisely the moment the world market is short, prompting the next exporter to do the same. The food price crises of 2007–08 and 2010–11 both followed this pattern, and both did more damage through policy cascade than through the underlying weather events.

For a household in a wealthy country spending a tenth of its income on food, a 6% rise in staple crop prices is an irritation. For a household spending half or more of its income on food, which describes a large share of the population in the regions covered below, it is the difference between three meals and two, or two meals and one a day.

When the Breadbaskets Fail Together

World grain trade rests on a small number of exporting regions: the US Midwest, the Southern Cone of South America, the Black Sea and eastern China, with Australia and India significant in wheat and rice. Five regional breadbaskets account for roughly 60% of global grain production. The system’s implicit insurance policy has always been that these regions do not fail in the same year: their weather has historically been close to uncorrelated, so a drought in one is covered by a surplus in another.

The system’s insurance policy has always been that the breadbaskets do not fail in the same year. Climate change is quietly cancelling this policy.

Work by Gaupp and colleagues shows that warming erodes exactly this assumption.¹⁴ Amplified Rossby wave patterns and hemispheric heat extremes couple the growing seasons of distant regions, converting independent risks into correlated ones.¹⁵ The probability of simultaneous failure does not rise gently with temperature; it ratchets up. The return period for simultaneous climate risk across all five maize breadbaskets falls from roughly every 16 years historically to under every 2 years in a world at 2°C.

Table 1. The ratchet: how correlated failure risk changes with warming Rows are expressed in comparable units so they can be read against one another. Gaupp’s return periods are for all five breadbaskets simultaneously exceeding their climate thresholds; the 1.5°C intermediate values are 21 years for wheat, 9 for soybean and under 3 for maize, which is why this is a ratchet rather than a slope. Tigchelaar’s figure rises to 86% at 4°C. McKinsey’s figures refer to the decade centered on 2030 under a high-emissions scenario.

Tigchelaar and colleagues put the same risk in the units a trader watches. The top four maize exporters are the United States, Brazil, Argentina and Ukraine, and between them they account for 87% of global maize exports. The probability that all four suffer simultaneous production losses greater than 10% in a given year is presently close to zero; at 2°C it rises to 7%, and at 4°C to 86%. At 2°C the projected decline across those four amounts to some 53 million tonnes, equivalent to 43% of current global maize export volume.¹⁶

The McKinsey Global Institute’s 2020 analysis puts the same risk in the units a planner uses. The probability of a greater than 15% global grain production shock roughly doubles by 2030, from about 1-in-100 to about 1-in-50 in any given year, giving an 18% chance of occurrence between now and 2035. A smaller but still severe shock of a 10% loss moves from a 6% to an 11% annual probability, and from a 46 to a 69% chance of occurring at least once in the next decade.¹⁷ That is the decade in which 2°C plausibly arrives.

A 2024 study by Zhang and colleagues puts numbers on the physical mechanism. At approximately 2°C, the likelihood that the world’s breadbaskets concurrently expose more than half their cropland to at least five days of extreme heat during the reproductive window in a typical year, not an exceptional one, rises from virtually zero in the 1984–2013 baseline to 43% for maize, 33% for rice and soybean, and 27% for wheat.¹⁸

The Limits of What Adaptation Can Do to Protect Crops

The World Bank’s Turn Down the Heat assessment contains a threshold that is easy to skim past: below roughly 2°C, adaptation offsets a substantial share of agricultural losses; above it, it becomes rapidly harder and covers only a shrinking fraction of the damage caused by the increasing temperature. 2°C is where the returns bend downward. The same report finds that under 2°C, South Asian crop production may fall by at least 12%, requiring more than twice the imports to meet per-capita demand, with childhood stunting rising by around 35% by 2050.¹⁹ The IPCC projects soft adaptation limits for multiple staple crops in many growing areas at 2°C, particularly in the tropics.

The Hultgren figure quantifies this from the other direction: adaptation and income growth together offset 23% of global losses at mid-century. Call that the best available estimate of what a farming system doing its rational best can recover. Note what ‘adaptation’ means inside these models. It means switching cultivar, shifting a planting date, drilling a well, installing drip irrigation. Every one of these changes requires capital, credit, information, secure land tenure and, frequently, a water right. Smallholders who lack the reserves do not adapt the way the model predicts. At 2°C their adaptation increasingly means land abandonment and migration, which the models score as adaptation and the households experience as catastrophic loss.

A result that points the other way

Honesty requires including one finding that cuts the other way. Zhao and colleagues (2025) analyzed 92,096 hybrid-trial observations across the US Corn Belt between 2000 and 2020 and found that modern breeding delivered both yield gains and improved drought resistance; the trade-off breeders had long assumed would bind progress did not. Projected forward, continued genetic improvement of this kind could cut drought-related yield losses by approximately 17.8% by 2100 relative to older hybrids.²⁰

The caveats are substantial and belong in the same breath. This is one crop, in one region, against one stressor. It addresses drought during grain filling, not extreme heat during pollination, which is the mechanism that does most of the damage to crops. It assumes the historical rate of developing genetic gains continues, and that farmers can afford the improved hybrids, fertilizers and other inputs that go with the new hybrids each season. It does not overturn Hultgren, whose estimates are already net of adaptation, and it does nothing for maize, sorghum or millet farmers in the Sahel or rest of the Global South.

A Map of Who Pays First

The additional hunger caused by a 2°C world does not distribute itself evenly, and the concentrations of damage and hunger are severe. South Asia carries roughly 33 million additional people at risk of hunger. Sub-Saharan Africa carries roughly 15 million additional hungry, plus approximately 43 million pushed below the poverty line. Across Sub-Saharan Africa, South Asia and Southeast Asia together sits around 80% of total exposure to additional hunger.

Figure 6. Where the additional exposure lands, and the populations already carrying a nutritional deficit.

The reasons compound rather than merely accumulate. These regions have the highest dependence on rain-fed agriculture and the thinnest irrigation coverage. They spend the largest share of household income on food, so the price channel of crop loss to price increase described above hits them hardest. Their staples are already grown nearest to their thermal ceilings, so a given increment of warming does more damage. Their safety nets are thinnest and their fiscal space to expand them smallest. Their populations are also the youngest, which means the nutritional deficits fall during the developmental window in which they may do permanent harm.

An independent analysis by Oxfam approaches the same map from the opposite end. Rather than ranking by modelled exposure, it ranks by revealed damage: the ten countries with the most extreme-weather-linked UN humanitarian appeals since 2000, where climate was assessed as a major contributor. They are Somalia, Haiti, Djibouti, Kenya, Niger, Afghanistan, Guatemala, Madagascar, Burkina Faso and Zimbabwe. Across those ten, acute hunger rose from 21.3 million people in 2016 to 47.5 million in 2021, a 123% increase in six years, with 18 million at emergency levels of hunger or worse.²¹

The same analysis supplies the arithmetic of responsibility that the modelling literature tends to leave out. Those ten countries account for roughly 0.13% of cumulative global carbon emissions. The G20 accounts for around 77%. The distribution of the damage is close to the inverse of the distribution of the cause, and no adaptation figure anywhere in this article alters that ratio. So far, the G20 are not fully meeting funding pledges to pay for adaptation in low-income countries hit hardest by climate change.

That is where the nutrition findings and the geography findings meet. The populations most exposed to calorie loss are, to a close approximation, the same populations carrying the nutrient losses described earlier. The same households absorb both shocks.

A third layer then sits on top: heat attacks food after harvest as well as before it. Higher temperatures accelerate spoilage and raise the risk of mycotoxin contamination, above all aflatoxin, a carcinogenic mold toxin in maize and groundnuts that worsens under exactly the combination of heat and drought stress a 2°C world delivers. Food-borne pathogen risks rise wherever cold chains are absent. Calories can be grown, harvested and delivered, and still not be safely eaten. Utilization is the pillar of food security that receives the least attention and is among the most temperature sensitive.

The Broad Base: Food Insecurity Now and at 2ºC

Next to chronic and acute hunger sits the third measure, and it is the broadest. The FAO’s Food Insecurity Experience Scale asks people directly whether, in the past year, they have had to eat less, skip meals, or go without food entirely for lack of money. By that measure roughly 2.3 billion people, about 28% of humanity, were moderately or severely food insecure in 2024, several hundred million of them severely food insecure, meaning they had at times run out of food or gone whole days without eating. The figure has barely moved since 2020 and sits roughly 680 million higher than in 2015. In sub-Saharan Africa it exceeds 58%, more than one person in two do not know where their next meal is coming from.²²

Food insecurity measures access, not calories or crisis, and that is what makes it the base of the other two measures of hunger: chronic hunger and acute hunger. It captures the enormous population living one shock away from starvation: not necessarily undernourished on the calorie accounting, not yet inside the IPC’s crisis phases, but unable to count on enough safe and nutritious food from one day to the next. Roughly 2.6 billion people already cannot afford a healthy diet at all, before any further warming arrives.

2°C carries no published headcount for this measure, for the same reason it carries none for acute hunger: food insecurity is observed in surveys, not projected by crop models. But its transmission belt has already been traced. Access is governed by price, and a 1% shortfall becomes a price rise several times larger, with a single hot season lifting food inflation for a year afterwards. A durable rise in staple prices does not simply tighten budgets; it moves people down the scale, and from severe insecurity into the acute pipeline the next section describes. A world that lets food insecurity spread is quietly filling the reservoir from which the next decade’s famines will be drawn.

The Sharp End: Will Acute Hunger Get Worse?

Everything modelled so far is chronic hunger: the slow arithmetic of calories per person per day, nutrient density, prices and purchasing power. That is what the crop literature is built to produce, and it is the measure behind the one million to 183 million range. It is not the measure that produces famines. Acute crisis tracks shocks rather than averages: what happens when a harvest fails, a currency collapses, a road closes or a war starts, and a household with no reserves has nothing between it and hunger or even famine.

Figure 7. The acute hunger picture in 2025: how severe, and what drove it.

How much of this is already climate related?

The honest answer is: a large and rapidly growing share of acute hunger is caused by climate change, but not the largest share. In 2025 conflict and insecurity were the primary driver for 147.4 million people across 19 countries, that is 56% of the total. Weather extremes were the primary driver for 87.5 million people across 16 countries in 2025, about a third of the total acutely hungry people in the world.²³

The trend inside that second number is the one to watch, especially in the context of 2°C of warming. As a primary driver of acute food insecurity, weather extremes accounted for 15.7 million people in 2020 and 87.5 million in 2025, a fivefold rise over a period in which global mean temperature moved by a fraction of a degree. Much of it traces to the 2023–24 El Niño, which devastated southern Africa, but this only temporarily rose temperatures to 1.6°C. A near-certain super El Niño for 2026–27 is already in the FAO and WFP hotspot outlook, which warns of deterioration across 13 countries and territories, with northeast Nigeria and Somalia joining Sudan, South Sudan, Yemen and Palestine at the highest level of concern.²⁴

For the causal link itself, the closest thing to a controlled experiment is the Horn of Africa. Between late 2020 and 2022, five consecutive rainy seasons failed across southern Ethiopia, Somalia and eastern Kenya, the worst drought in four decades. Attribution analysis found the agricultural drought was made roughly 100 times more likely by human-caused global warming, and that an event of that severity would not have occurred in a climate 1.2°C cooler.²⁵ More than 20 million people were pushed into Crisis or worse, and in Somalia an estimated 43,000 excess deaths occurred in 2022 alone, about half of them children under five.²⁶

A child stunted in a famine year is stunted permanently. There is no later harvest that gives those years of nutrition back. Stunting causes a lifetime of physical, metabolic, and cognitive challenges.

What 2°C does to the shock machinery

No published study puts a number on how many people will be in acute hunger or famine in a 2°C world. The IPC classifies observed conditions rather than projecting them, and the humanitarian and conflict variables that dominate it are not forecastable on a multi-decade horizon. Anyone offering a precise figure is extrapolating past the evidence. What can be done instead is to ask, driver by driver, whether the machinery that generates acute crises runs more often at 2°C. On every input for which projections exist, it does, meaning it is much more likely that acute hunger will increase in a 2°C world.

· Drought exposure rises. The IPCC’s assessment finds an additional 350 million urban residents exposed to water scarcity from severe drought at 1.5°C, rising to 410.7 million at 2°C; across all populations the additional exposure roughly doubles between the two thresholds. Drying is amplified in the tropics, which is where the protracted crises already are.²⁷

· Extreme heat exposure rises far faster. Around 700 million people, approximately 9% of the world, would face extreme heatwaves at least once every twenty years at 1.5°C. At 2°C the figure is more than 2 billion, or 28% of the world.²⁸ Heat does not only cut yields; it destroys the casual agricultural labor that landless households in crisis contexts depend on for the income to buy food.

· Shocks become more correlated and more frequent. The breadbasket evidence above is the machinery of acute crisis stated in physical units. A correlated shock is worse for acute hunger than for chronic hunger, because the mechanism that normally rescues a failed region, imports from one that did not fail, is exactly what a correlated shock removes.

· The price channel is an acute-hunger channel. The twelve-month persistence of heat-driven food price inflation matters far more to a household in Phase 2 hunger than to one in a wealthy country. Phase 2 acute hunger is where the people who fall into Phase 3 severe acute hunger come from, and a year of elevated prices is how they get there.

· Recovery capacity is not being rebuilt. The same 33 countries have appeared in every edition of the crisis report since 2016, and more than 80% of the severely food-insecure now live in protracted crisis contexts. These are places where a bad harvest is no longer a setback but a cumulative loss, because the resilience that used to absorb it has gone. Each new shock lands on the residue of the last.

The estimate, and its uncertainty

Setting those pieces together supports a directional judgement rather than a point estimate, and it should be labelled as such: this is inference from the drivers, not a projection anyone has published.

Acute food insecurity will almost certainly be worse at 2°C than it is now, and the mechanism will be frequency in addition to the then level of the acute hunger crises. The expectation is not that the world settles at a permanently higher number, but that the peaks come closer together. A bad year arrives before the previous one has been absorbed. Set the El Niño impacts beside a fivefold rise in weather-driven acute hunger over five years and a fraction of a degree, and a doubling of the weather-attributable component by mid-century reads as conservative. Whether the total number of people suffering from acute hunger doubles depends overwhelmingly on conflict, which nobody can forecast and which can be expected to worsen where there is less food. Conflict, climate and the cost of food are the three factors driving rates of hunger around the world.

The number that deserves the closest watch is not the headline count but the Catastrophe population. It has risen ninefold since 2016 to 1.4 million people in 2025, and famine was confirmed in two places in the same year in 2025 for the first time. Catastrophe is where a shock meets the absence of a response, which makes it the most sensitive indicator of both trends at once: hazards increasing, humanitarian capacity contracting. The 2026 crisis report expects no improvement, reporting the fall in humanitarian food-sector funding at around 39% against 2024, with development assistance down at least 15%. In the past, peoples of the world rallied to provide food to people in famines, (remember Live Aid?), and the fact that this did not happen to any great extent in 2025 does not bode well for the hungry people when 2°C arrives.

All of this points at the conclusion the chronic analysis reached, arriving from the other direction. The increase in acute hunger in a 2°C world is real, already growing, and already measurable in mortality rates - people are dying. But the difference between a bad decade and a catastrophic one still runs through whether anyone is funded to respond, whether trade stays open when the shock lands, and whether countries in permanent crisis are given any means of rebuilding the buffer that used to absorb the next crisis. WFP puts the return on taking anticipatory action at three to seven dollars saved for every dollar spent. 2°C decides how often the shock arrives. It does not decide how many people it kills.

What It Means in America, Britain and Australia

Crops do not fail gradually. The relationship between temperature and yield established by Schlenker and Roberts is sharply asymmetric and piecewise: below a crop-specific threshold, around 29°C for maize, 30°C for soybean, 32°C for cotton, additional warmth is mildly beneficial; above it, damage accumulates several times faster.²⁹ Warming does not drive a smooth curve. It moves more of the growing season onto the wrong side of a hard biological edge.

Figure 8. The temperature threshold above which US crop losses accelerate, and what crossing it costs.

The modelled consequences for the United States are stark: reductions of 30 to 46% in maize, soy and cotton yields by 2100 under slower warming, and 63 to 82% under unmitigated warming. Hultgren’s global analysis projects maize losses of up to 40% for mid-latitude grain belts even after farmers adapt, and separate work by Liu and Basso projects net US soybean yields will be 26 to 57% lower by 2050.³⁰ The climate is already moving underneath the system: roughly half the country shifted a half-zone warmer between the 2012 and 2023 revisions of the USDA Plant Hardiness Zone Map.³¹

American hunger from climate change nevertheless arrives through a different door than in Malawi or Bangladesh. The United States is a net exporter with deep reserves and a highly capitalized farm sector; supermarket shelves will not go empty. What changes are the prices on the shelf and, upstream, crop insurance costs, farm incomes, land values and the fiscal exposure of federal support programs. Low-water events on the Mississippi already interrupt grain movement in drought years. There is also a trade dimension the Hultgren authors state bluntly: as northern latitudes gain and mid-latitudes lose, agricultural advantage is going to transfer to Canada, Russia and China.

The households that feel these price rises are the ones already spending a high share of their income on food, and they feel it in the same year that public budgets are absorbing disaster and insurance costs. It is the price elasticity described earlier, operating inside a wealthy country: a modest availability shock, a multiplied price response, and the impact concentrated on the poor and working classes.

Britain’s exposure is structurally different, because Britain is a net importer of food. It is the case where the correlated-failure mechanism described earlier lands directly on a wealthy population. Two of the three worst UK wheat harvests on record have occurred this decade, in 2020 and 2024, both caused by relentless rainfall and wheat self-sufficiency fell from 96% in 2023 to 79% in 2024, with imports the following autumn running at double the five-year average. Across 2020 to 2024 the cumulative shortfall exceeded seven million tonnes. Then 2025 failed from the opposite direction, in one of the hottest and driest springs and summers on record. 2026 looks like being even worse. A country short of wheat in a wet year and short again in successive dry ones is not having bad luck. It is experiencing climate variance; both can be bad and expected to get worse as 2°C is reached.³²

The second half of that exposure is that Britain’s suppliers sit in the regions this article has already identified as losing when the temperature rises to 2°C. More than 90% of imported vegetables come from the Mediterranean, with Spain being the largest single supplier. Spain has been in a historic drought. Headline self-sufficiency across all farming sectors has fallen from 86 to 78%. Domestic shortfall and supplier shortfall are not independent events; they are two expressions of the same warming, which is the correlation problem operating at the scale of one country’s shopping basket.³³ Europe is also the fastest warming continent meaning the effects of warming arrive here first.

Australia sits between the two and supplies the longest-running natural experiment. Its wheat yields stopped rising in 1990. Hochman and colleagues simulated 50 representative sites across the grain zone and found that water-limited yield potential fell 27% between 1990 and 2015, driven by declining rainfall and rising maximum temperatures, with elevated CO₂ preventing a further 4% loss. National yields nonetheless held flat, because technology closed the gap between what farmers achieved and what the climate permitted, lifting relative yields from 39 to 55% of potential.³⁴

There is a qualification here that cuts both ways. The Zhao breeding result is a Corn Belt study, and if any agricultural region on earth has the pipeline, the capital and the agronomic data to bend its own curve, it is this one, and that is the strongest reason to think the American numbers may land nearer the optimistic end of their range. The Australian record is what taking a bet on agriculture looks like after twenty-five years: it paid, and it paid by spending the yield gap it was closing, which is why Hochman’s authors end by asking whether the gains can continue. Neither case is a reason to expect the same in the Sahel or the rest of the Global South.

The Window That Is Still Open

If most of the distance between one million and 183 million is policy, then the policies that should be implemented need exploring. Four fronts carry most of the leverage.

First, keep the grain moving

This is the largest single lever in the literature and the cheapest to implement. The difference between a world in which staple crop trade stays open during a crop price shock and one in which exporters close their borders is a swing of approximately 53 million people at risk of hunger. It requires no new technology, no infrastructure and no transfer of funds. It requires only that governments refrain from doing the thing they are most tempted to do at the worst possible moment. The temptation is strongest when the stakes are highest and price shocks and grain availability are at their worst. The mechanism by which countries agree not to close their borders has to be built in advance: pre-commitments against export bans, exemptions for humanitarian purchases, and regional reserves. Such an agreement takes negotiation and time. The process to agree to open borders must start now, before the crisis really starts to gain momentum.

Second, breed for nutrition and break the monoculture

Biofortification now has a hard target rather than a general aspiration, and the nutrient figures above state exactly what it is up against. Zinc-biofortified wheat and rice, high-iron beans and pearl millet, and quality-protein maize are existing technologies with existing delivery channels. What they lack is scale.

Alongside biofortification sits diversification away from over-reliance on four dominant monocultures. Millets, sorghum, cassava and legumes carry higher thermal tolerance and, in several cases, better micronutrient density than the crops they were displaced by. Rebuilding seed systems, agronomic knowledge and consumer demand for them is slow work, which is an argument for starting now rather than for postponing, given we may have only a decade to work with.

Third, fund the response before the failure, not after it

The compressed timeline established at the start of this article is the whole argument here. If 2ºC plausibly arrives in the mid-2030s rather than the 2050s, then adaptation finance disbursed in the 2040s is finance disbursed after the event. Irrigation, on-farm and regional storage, decentralized solar-powered cold chains, processing hubs close to production, extension services and seed systems all take the better part of a decade to plan, fund and build. Front-loading is not a preference about spending profiles. It is arithmetic about lead times.

Fourth, build safety nets that trigger on a forecast, not on a famine

The FAO’s 2026 affordability data provided this warning: approximately 2.6–2.7 billion people, 31.3 to 32.5% of the world, already cannot afford a healthy diet before any 2ºC shock arrives.³⁵ A 6% staple price move applied to a household already priced out of adequate nutrition does not produce belt-tightening. It produces substitution into cheaper, less nutritious calories, which compounds the dilution effect described earlier.

The design feature that matters is automaticity. Safety nets that expand by discretionary political decision expand late, after the harm is done and after the politics have hardened. Safety nets indexed to observable triggers, such as food price indices, rainfall deficits, satellite-observed vegetation stress which release resources when certain thresholds are crossed. The technology for this exists and such systems are in operation in several countries. Expansion of these systems is a question of coverage and financing and getting countries to allow these inventions. Linking safety net response to climate signals such as Earth’s Energy Imbalance may even provide an outlook away from natural variability in weather.

Every famine that follows a forecast drought is a policy choice made a year earlier, by people who had the forecast and failed to act.

The direction of travel

Everything above is written as though these four fronts were open. But we do not live in an ideal rational world. Three of them are currently closing, not through climate stress but by political choice.

2025 brought the largest single-year contraction in development assistance ever recorded. Aid from OECD donors fell 23.1% in real terms to $174.3 billion dollars, back to roughly where it stood in 2015 when the 2030 Agenda was adopted. The United States drove three-quarters of the fall, cutting its own aid by 56.9%, the largest reduction by any provider in any year on record, with Germany, France, the United Kingdom and Japan all cutting foreign aid as well. Humanitarian assistance fell 35.8%, and core contributions to the UN system fell 27%. A further 5.8% fall is projected for 2026.³⁶

The incidence is not evenly spread, and the geography should look familiar. The OECD projects bilateral aid to the least developed countries falling by 13 to 25%, and to sub-Saharan Africa by 16 to 28%. That is the same map as the 80% of climate exposure described earlier, and as the 60% of the 2030 chronic-hunger projection that sits in Africa.

The operational consequences are already measurable. In Uganda, donor shortfalls forced the suspension of food assistance for a million refugees and ration cuts of up to 80%, alongside a rise in global acute malnutrition among refugees from 5.5% at the end of 2024 to 7.7% in late 2025.³⁷ Peer-reviewed modelling of the US cuts alone projects more than 14 million additional deaths by 2030 across 133 countries, including 4.5 million children under five.³⁸ None of those cuts were forced by anything other than a political choice.

None of this makes the four fronts wrong. It makes three of them counterfactual. Front-loaded adaptation finance and automatically triggered safety nets are the levers that set the multiplier between one million and 183 million, and both are being dismantled in precisely the years before 2ºC arrives, which raises the standing of the one lever that costs nothing. Keeping staple trade open is the only front that does not require money that is no longer there, and on the accelerated timeline it may be the only one that can still be built in time.

Conclusions - The 2ºC Warning

Food is not merely an economic commodity. It is the baseline condition on which every other form of order rests. Governments survive inflation in most things; they survive it in bread less often. The historical record of price spikes in staple grains is also a record of unrest, of conflict, of migration, of state capacity failing under a load it was not designed to carry. When the harvest fails in several places at once, the consequences do not stay agricultural for long.

The instinct in wealthy countries is to treat this as somebody else’s emergency, buffered by distance and purchasing power. That instinct misreads the system twice over. A globally integrated food network transmits scarcity through price, and price reaches everywhere the network reaches. And the modelling does not even grant wealthy agriculture the protection it assumes: the steepest projected losses fall on today’s best growing regions, because they have the least headroom left. Wealth buys position in the queue. It does not buy exemption from the queue.

Which returns the argument to where it began. One million to 183 million. The physics that sets the shock is now largely determined; the acceleration in the energy imbalance has taken the choice about whether 2°C arrives, and much of the choice about when, out of our hands. What remains entirely in our hands is the multiplier: whether borders stay open, whether safety nets hold during food price shocks, whether the money arrives before the harvest fails rather than after.

The 2°C dinner table is being set. What ends up on it, and who is seated at the table, is still, for now, ours to decide. It will not be for much longer.

Action you can take

The choices remaining are narrowing as 2°C approaches faster than anyone anticipated and are therefore far more consequential. They are being made now, in budget lines and trade rules and appropriations votes, by people who will not do anything about it unless somebody demands that they do. So, ask them.

The aid contraction described above was not a natural disaster; it was a set of votes and decisions made by elected officials. Votes can be taken again to reverse those decisions. The trade commitments that keep grain moving in a crisis are negotiated in advance or not at all. The safety nets that decide whether a price spike becomes hunger are written into domestic law by legislators who answer to constituents.

· Call your representatives, at all levels, and ask what they intend to do about food security before the shock arrives rather than after it.

· Ask what they are doing to restore humanitarian and development funding. Ask whether they will commit, publicly and now, against export bans in the next crisis.

· In the US, demand that USAID and SNAP funding be restored and other actions are taken in anticipation of the super El Niño we are about to experience. We have 150 years of data; we know where crises are going to occur. We should be stocking food and other humanitarian supplies before these crises happen.

A note on the evidence used

The figures in this article come from three classes of evidence, and they do not deserve equal weight. Observed and attributed is the strongest: the price cases documented by Kotz and colleagues, the USDA hardiness-zone revision, the UK harvest record and the rise in the Earth’s energy imbalance are all measurements of events that happened. Assessed with stated confidence covers the IPCC’s nutrient-dilution findings, which carry an explicit high confidence label. Modelled projections, which include Hultgren, Smith and Myers, Gaupp, Tigchelaar, Zhang, Zhao, Hochman and the McKinsey analysis, are conditional on assumptions about emissions, adaptation speed, trade and income growth, and the conditions are the argument.

This is why the headline range is so wide. Studies at the low end assume open trade, effective adaptation and continued income growth; studies at the high end assume the opposite. Neither is wrong. They answer different questions, and reporting the range honestly is more useful than selecting a point estimate that flatters a position. Three things would move the numbers toward the optimistic end: sustained genetic gains of the kind Zhao documents, a durable regime holding staple trade open through a synchronized shock, and biofortification reaching scale faster than dilution accumulates. Three would move it the other way: a synchronized breadbasket failure arriving before adaptation finance does, a cascade of export restrictions, and the contraction in assistance persisting through the 2030s.

How seventy percent of the world’s great aquifers came to be in decline, why Lake Mead hit its all-time record low three days ago, and what happens in Somalia, in Iran, in the Dry Corridor of Guatemala, and in the Imperial Valley of California when the water that grows a family’s food runs out from under them.

The Ledger Nobody Kept

At some point between midnight and one in the morning on Friday, August 7, 2026, the surface of Lake Mead fell to 1,040.46 feet above sea level. It was the lowest the reservoir has stood since it was filled behind Hoover Dam in the 1930s, breaking the previous record set on July 28, 2022 by a margin that Reclamation puts at four one-hundredths of a foot and some wire reports put at a tenth. Either way it is a matter of inches, which is the sort of margin that makes a milestone easy to dismiss.¹ By Saturday morning, Lake Mead held only 7.0 million acre-feet against its capacity to hold 26.1 million acre-feet: That is only 26.8 percent full. Lake Powell, upstream, stood at 22.8 percent full. Federal forecasters expect Mead to set a new low record in nearly every month from here through 2028. Those projections do not yet account for the mandatory federal cuts now expected to be imposed on the states by the Interior Department.²

On July 31, the Interior Department published the framework that will govern the Colorado River for the next decade: up to three million acre-feet of mandatory reductions must be made in water use, reductions falling entirely on Arizona, California and Nevada. These cuts will be imposed by the Secretary of the Interior after the seven basin states failed to produce an agreement of their own.³ What those reductions do to the food supply is the subject of a later section. What they mean here is simpler. The decline of the largest reservoir in the United States has stopped being only a hydrological question and become an allocation question, about which farms lose water, and about who decides.

This is a matter of Western water politics and of food. It is also a matter of who gets to stay where they were born and who will be forced to move due to no water.

Six months earlier, in January, the United Nations University’s water institute published an assessment of the world’s water reserves that put the American Southwest in a context most Americans never see. Its title is Global Water Bankruptcy, and the accounting was blunt: seventy percent of the world’s major aquifers are in long-term decline. A broader test than the rate thresholds used in the peer-reviewed work discussed below, and a lower bar, but a bar that seven aquifers in ten now fail. More than forty percent of the water used for irrigation on Earth now comes out of aquifers that are being steadily drained. Three billion people live in places where total water storage, both surface and subsurface together is falling, and more than half of global food production is concentrated in exactly those places. Some 170 million hectares of irrigated cropland, an area larger than France, Spain, Germany and Italy combined, sits under high or very high water stress.⁴

That is the ledger. It has been running a deficit for decades, and almost no country keeps an honest publicly available record of aquifer water levels.

Figure 1. One shortage, four separate failures, one destination. Unlike a drought, aquifer depletion does not end. It works through four independent channels at once, each of which alone can take land out of production, and it arrives at the same place a season or two later. The compensation step is what separates the American case from the Somali one: where farmers are paid to fallow, the displacement does not occur.

4Hunger.org has spent this year documenting three shocks to the world’s food supply in sequence: the fertilizer supply collapse that followed the closure of the Strait of Hormuz in February (see Fertilizer Famine); the two-year American drought that drove the U.S. cattle herd to its smallest size since 1951 and the wheat crop to a 22 percent year-over-year collapse (see Parched Ground); and the record El Niño now building in the Pacific (see Scorched Harvest)⁵. Each of those is an event. Each has a start date, a peak, and a plausible end.

This article is about the thing underneath all of them, which is not an event at all. It is a slow, compounding, almost entirely invisible drawdown of the water the world’s food supply is built upon, and there is no foreseeable end to the draining of these water resources, because there is no end to the needs for water that are overusing these water reserves. An El Niño passes. A strait reopens. An aquifer that has been pumped past its recharge rate for sixty years does not recover in a good year, or in a good decade, or in some cases there is nothing at all that will enable the aquifer to recharge and rebound.

“A drought takes a harvest. A depleted aquifer takes the farm, and then the whole town, and then the option of ever farming in the region again.”

A Map of What Is Already Gone

In 2024, a team led by Scott Jasechko published in Nature what remains the most comprehensive picture of global groundwater ever assembled: roughly 170,000 monitoring wells across 1,693 aquifer systems in more than forty countries, covering about three-quarters of the world’s groundwater withdrawals. Thirty-six percent of those aquifer systems are declining faster than 0.1 meters a year. Twelve percent are falling faster than half a meter a year. In thirty percent of them, the rate of decline in 2000–2022 was faster than it had been in 1980–2000, an acceleration of water withdrawal more than twice as common as chance would produce.⁶

Figure 2. The state of the world’s groundwater. Of 1,693 aquifer systems monitored across more than forty countries, roughly a third are falling faster than 0.1 metres a year, and in thirty percent the decline has accelerated since 2000. The sixteen percent that are recovering did so after deliberate intervention, not on their own. Shares from Jasechko et al., Nature, 2024.

The geography of the decline identified maps almost perfectly onto the geography of the world’s grain.

In the United States, the High Plains Aquifer, the Ogallala aquifer, underlies 111.8 million acres across eight states and supplies roughly thirty percent of all groundwater used for irrigation in the country.⁷ The USGS puts the area-weighted decline from predevelopment to 2019 at 16.5 feet, which sounds survivable until the number is disaggregated by state. Texas has lost 44.1 feet. Kansas has lost 27.3. Nebraska has lost four-tenths of a foot.⁸ That single table explains why there is no unified Ogallala aquifer politics: the states with the water have no reason to accept limits, and the states without it are past the point where limits will help. In the Texas High Plains Water District, average saturated thickness in the Ogallala is now 51 feet.⁹ A 2020 study projected that twenty-four percent of currently irrigated High Plains land will be unable to support irrigation by 2100. In a detail that earlier work missed was that most of the acres that lose irrigation will fall back to dryland farming with crops that can grow on rainfall alone, with food production at roughly a third of that of irrigated yields, Unfortunately, what the study also found was that not all of the farmland will be able to support even dryland farming. On thirteen percent of the transitioning land the soil is too thin to raise a rainfed crop at all, and it will go back to grazing. Irrigation, on that ground, was never improving the soil. It was substituting for good soil and allowing crops to grow there that would ever have on the poor soil alone.¹⁰

Figure 3. One aquifer, eight political realities. Water-level change in the High Plains aquifer from predevelopment to 2019. Texas has lost more than a hundred times what Nebraska has, and South Dakota has gained. This distribution is why there is no unified Ogallala politics: the states with water have no reason to accept limits, and the states without it are past the point where limits would help. Figures from USGS Scientific Investigations Report 2023-5143, Table 2.

In India, the Central Ground Water Board’s 2025 assessment found 730 of the country’s 6,762 groundwater assessment units classified as over-exploited. Punjab, the state that fed the Green Revolution, is now extracting 26.27 billion cubic meters a year when the sustainable removal from the aquifer is only 16.80 billion cubic meters, an extraction of 156 percent of the replenishable removal. In 111 of Punjab’s 153 blocks, more water leaves the ground each year than enters it. In Sangrur district the figure is a removal of 310 percent of the replenishable removal.¹¹ Both of these signal aquifers being overused and which will be depleted over time.

In Iran, where agriculture consumes roughly ninety percent of all available water, groundwater extraction has caused land subsidence across 31,400 square kilometers. Almost two percent of the country’s land surface is sinking faster than a centimeter a year, with more than a hundred sites exceeding that rate and one area near Rafsanjan dropping 34 centimeters annually. Subsidence is what happens when unconsolidated aquifer systems containing significant layers of fine-grained, compressible materials like clay and silt, aquitards, lose the pore water that helps carry the weight of everything above them: the grains pack together, the layers thin, the ground surface drops, and the space that once held water closes and does not reopen.¹² Seventy-seven percent of that fast subsidence correlates with where Iran’s most productive agriculture occurs. Most of it is, in the authors of the report’s framing, “irrecoverable”: inelastic compaction accounts for at least sixty percent of the deformation, which means the pore space of the aquifer which holds the water collapses and much of the aquifer’s capacity to hold water again is permanently lost.¹³

In Afghanistan, the Kabul aquifer has dropped 25 to 30 meters in a decade, with extraction exceeding recharge by 44 million cubic meters a year. Nearly half the city’s wells are already dry.¹⁴

There is one genuine counter-example. On the North China Plain, where water tables were falling one to two meters a year, By 2008 the plain had pumped away roughly 60 cubic kilometers of groundwater more than the rain put back: about 48 million acre-feet, or two and a half years of everything the entire Colorado River basin consumes.

China then went at the problem from both ends at once. It brought new water in, and it forced less water out. The new water came through the South-to-North Water Diversion, a canal system built to carry 9.5 cubic kilometers a year north from a reservoir on the Han River. In 2023 it actually delivered roughly 4.3 million acre-feet, and about fourteen percent of everything the region used that year. The reduction came from enforced limits on pumping, which cut what farms, factories and cities drew out of the ground by around 12 cubic kilometers a year. That is close to 10 million acre-feet: a single year’s saving roughly half the size of the entire Colorado River’s annual consumption.

Together they produced something no one had documented at this scale: the water tables rose about 0.7 meters a year across 130,000 square kilometers, an area the size of Louisiana, between 2020 and 2024, By 2024 the water in the aquifer stood higher than it had in 2005.¹⁵ Aquifer depletion, in other words, is not a law of physics. It is a policy outcome. It can be reversed by policy, at enormous cost, where a state decides to as long as the soils have not collapsed.

The Ground Gives Way, But It Does Not Shake

One question follows naturally from all of this, and it is worth answering plainly, because the answer is usually gotten backwards: does draining an aquifer cause earthquakes?

Very largely, no, and the physics runs opposite to the intuition. Pumping water out of rock lowers the pressure in its pores, and lower pore pressure presses the two sides of a fault together more firmly rather than loosening them. Whatever destabilizing effect exists arrives indirectly, as the drained rock contracts and transfers stress to its neighbors, and as the crust flexes upward once the weight of the water is gone.¹⁶

Scale settles it. Groundwater withdrawal changes crustal stress by something on the order of one to fifteen kilopascals. An earthquake releases a thousand to ten thousand. Research published this year found groundwater cycles in northern California associated with as much as a ten percent modulation in the rate of small earthquakes, and noted, in the same breath, that ocean and earth tides of equivalent strength produce no such effect at all.¹⁷ In the global database of human-induced earthquakes, groundwater extraction accounts for under one percent of the 1,377 recorded cases; hydraulic fracturing, mining and reservoir impoundment account for most of the rest.¹⁸ The most heavily monitored test of the mechanism is the Groningen gas field in the Netherlands, where pore pressure fell by more than ten times what the most exhausted aquifer experiences, and the largest earthquake in fifty years was magnitude 3.6.

None of this describes injection, which is a different process with a different record. Pumping fluid into the ground raises pore pressure and unclamps faults, and it took Oklahoma from one or two magnitude-3 earthquakes a year before 2009 to 888 in 2015, including a magnitude 5.8. The two are routinely confused, and they are opposites.¹⁹

What depletion does to the ground is not seismic, and it is not in dispute. The ground sinks. More than eighty percent of documented land subsidence in the United States is a consequence of groundwater use, across more than seventeen thousand square miles in forty-five states, and Arizona has mapped a hundred and sixty-nine miles of earth fissures opening above emptied basins. These are not earthquakes. They are the slow and permanent collapse of the space the water used to occupy, the more consequential hazard, and the one from which there is no recovery.

Figure 4. What depletion looks like underground. Pumping lowers the water table decade by decade; when it falls below a well’s screen the well fails, and when it falls below a clay layer the clay compacts, the ground surface drops, and the pore space that held the water closes permanently. Salt concentrates at the surface as the water that remains gets more brackish. Schematic, drawn to the mechanisms described in this article; vertical scale is exaggerated.

Three Ways a Water Shortage Kills a Harvest

One: not enough water at the one moment that matters

A crop does not need water evenly through the duration of its growth. It desperately needs abundant water at two or three specific points, and a deficit that arrives during flowering or during grain fill does damage that later rains cannot undo. Wheat builds its pollen about a week before it flowers, in a stage botanists call the young microspore, and this is the thirstiest moment in the plant’s life. Developing pollen grains cannot feed themselves; they are supplied with sugar from the leaves. A plant short of water closes its pores to stop losing moisture, which also shuts down photosynthesis, which starves the anthers, the small sacs at the tip of the stamen where pollen is made. The pollen still forms. It simply forms sterile.

What follows is a failure that conceals itself. The plant does not die. It has water enough to stay green, put up a head, and flower on schedule. But nothing is fertilized, no grain sets, and the crop stands in the field looking like a crop until the combine goes through and finds husks. Rain the following week changes nothing. The pollen died during the dry days, and a plant cannot make it twice.

Grain filling is the second window, and it fails in a different currency. Once a kernel has been fertilized, the plant spends roughly a month pumping starch into it, drawing on two accounts: the sugar its leaves are making now, and the sugar it banked earlier in the stem. Drought closes both. The pores shut, photosynthesis falls away, and the plant, reading the shortage as the end of its season, begins shutting down early, drying its leaves and halting the deposit before the kernel is full. Nothing is missing from the head this time. Everything in it is simply too small. And because a dry spell usually arrives with heat, the two stresses stack: high temperatures shorten the filling period on their own, even where there is water enough. The farmer learns the result at the elevator, where shriveled grain and low-test weight are docked once on the scale and again on the price. Between them, these two windows account for most of what a dry year actually costs. One sets how many grains a field will carry. The other sets what each of them weighs. Rain in between is welcome. Rain after either is too late.²⁰

In a controlled Chinese trial on two winter wheat cultivars, drought imposed at that single stage cut viable grain number on the main stem by 51.8 percent in the drought-tolerant variety and 79.5 percent in the sensitive one.²¹ The field still looked like a wheat field. But, it was not one because the plants held no wheat.

This is why “flash droughts,” the rapid-onset soil moisture collapse driven by heat and wind rather than by a long rainfall deficit, has become an important new term of art. Global projections show flash drought frequency rising through the century, and the cropland-specific numbers are the ones that matter here: under a high-emissions pathway, the annual risk of flash drought on North American cropland rises from 32 percent in 2015 to 49 percent by 2100; European cropland from 32 percent to 53 percent; African cropland from 35 percent to 47 percent.²²

The best current modeling of what this does to the food supply is a study published in Nature Communications this year. Run through 2050 under a middle-of-the-road emissions scenario, drought reduces globally averaged production of maize, rice, soybean and wheat by somewhere between roughly 0.2 percent and just under 2 percent. That is a small number, but the story is in the distribution. Maximum country-level production losses exceed 10 percent in 62 countries and exceed 20 percent in 24 countries, with single-crop maxima reaching 76 percent for maize, 67 percent for rice and 64 percent for wheat.²³ A global food system can absorb a two percent average. It cannot absorb a 76 percent maize failure in a particular country that eats its own maize and has no foreign exchange to import someone else’s.

Figure 5. Two windows, two currencies. A water deficit does the most damage at two specific moments, and it damages the crop differently at each. Stress at flowering sterilizes pollen and removes grains that never form; stress during grain fill leaves the grains in place but light. Rain between the two windows helps; rain after either does not. The curves are illustrative of the two sensitivity windows, anchored to measured grain-number losses of 51.8 and 79.5 percent in controlled winter-wheat trials.

Two: the wrong kind of water

A. Salty

When fresh water runs short, farmers do not stop irrigating. They irrigate with what is left, brackish groundwater, drainage water, recycled wastewater, and in hot climates the evaporation concentrates the salts that come with it. The result is a slow poisoning that is invisible until it is permanent and kills the crop.

The mechanism is worth understanding, because it explains why the damage is so hard to undo.

A root does not pump. It has no muscle for drawing water out of soil. It relies on osmosis: water moves on its own from where dissolved salts are dilute toward where they are concentrated, and because the sap inside a root is saltier than the water in ordinary soil, water flows inward without the plant spending anything to move it. That gradient is the entire engine.

Salt in the soil weakens that gradient, and enough of it reverses the direction. When the water around the roots becomes as salty as the sap inside them, water stops entering the plant altogether. When it becomes saltier still, water begins moving the other way, and the soil draws moisture back out of the root. The soil is visibly damp. The plant is in drought. It dies of thirst standing in wet ground.²⁴

What does get in causes a second kind of harm. Sodium and chloride accumulate in the leaves and scorch them, and they crowd out the potassium and nitrate the plant needs, so a salt-stressed crop is starved as well as parched.

And here is the trap. Every irrigation adds a little salt, and evaporation removes pure water while leaving that salt behind, so concentration climbs season after season. The only way to reverse it is to flood the field with enough clean water to carry the salt down below the root zone. The cure for salinity is water in abundance, which is precisely what a farmer who has resorted to brackish water does not have.²⁵

In December 2024, the FAO published the first global assessment of salt-affected soils in fifty years. 1,381 million hectares, 10.7 percent of the Earth’s land area, are salt-affected, with roughly another billion hectares at risk. Ten percent of irrigated cropland and ten percent of rainfed cropland are already affected. Under current warming trajectories the affected share of the global land surface could reach between 24 to 32 percent by the end of the century. In the worst-hit regions, salinity stress costs up to seventy percent of yield in crops like rice and beans. Ten countries, Afghanistan, Argentina, Australia, China, Iran, Kazakhstan, Russia, Sudan, the United States and Uzbekistan, hold seventy percent of the world’s salt-affected soil.²⁶ The most-cited estimate of the annual global cost of salt-induced degradation in irrigated areas is $27.3 billion in lost crop production. That figure is more than a decade old, counts nothing but forgone yield, and has never been replaced; FAO’s 2024 global assessment, the first in fifty years, did not attempt one. What has been measured since is the loss in food rather than in money. The World Bank puts the annual production lost to water salinity at 124 trillion kilocalories, enough to feed more than 170 million people every day. That the best current accounting of salinization is denominated in calories rather than dollars is itself a finding about how seriously the problem has been costed.²⁷

B. The Water That Carries Something Else

Salinity is the slow failure, and it is at least visible in the yield. There is a second failure that never appears in production statistics at all, because it does not damage the crop. It damages the people who grow it and the people who eat it.

When a city runs short of fresh water, the one supply that remains reliably available to the farms on its edge is the water the city has already used. Roughly 29 million hectares of the world’s irrigated land, about a tenth of the total, is watered from sources carrying a substantial load of urban wastewater, and about 95 percent of that is untreated or inadequately treated. Formal, engineered reuse of properly treated effluent covers perhaps 1.5 million hectares. The ratio of unsafe to safe is around thirty to one.²⁸

The reason is cost, and the pattern is exactly what you would guess. Of the 267.5 billion cubic meters of municipal wastewater the world produced in 2023, 45 percent was discharged with no treatment whatsoever. High-income countries treat 91.5 percent of theirs. Low-income countries treat 5.8 percent.²⁹

What that water carries is not hypothetical. In Kumasi, Ghana, farmers irrigating with wastewater carried Ascaris infection were 15.8 percent against 6.0 percent in a matched control group, about four times the odds.³⁰ In Santiago, Chile, where 13,500 hectares of salad crops were irrigated with raw sewage, typhoid ran at 210 cases per 100,000 at its peak, and when cholera arrived in 1991, 68 percent of the first 41 cases had eaten raw wastewater-irrigated salad. Chile banned the practice. That is the encouraging half of the story: this is a solved problem wherever anyone decides to follow the solution, do not water food crops with sewage.³¹

The residue is more permanent than the pathogens. In Mexico’s Mezquital Valley, irrigated with Mexico City’s untreated sewage for roughly a century, soil chromium now runs 7.7 to 8.6 times background and cadmium 3.0 to 4.7 times. Antibiotic-resistance genes in those soils are two orders of magnitude more abundant than in comparable fields.³²

Treated wastewater reuse is not a hazard; it is one of the best adaptations available for making due with the limited water resources that we have. Israel reuses about 87 percent of its treated effluent, supplying roughly half its agricultural water. Even the untreated kind carries real value, the nutrients in it are worth $179 to $451 per hectare per year, are taken up more efficiently than synthetic fertilizer, and after forty years leave soil carbon half again higher. When Mexico built a treatment plant that stripped those nutrients out, Mezquital farmers protested, and on the economics they were not wrong. The problem is not that poor farmers use wastewater. It is that they are made to use it raw and untreated.³³

Figure 5. Who treats their sewage before it reaches a field. Share of municipal wastewater receiving any treatment, 2023. The farms most likely to be irrigating with untreated waste are in the countries least able to treat it, which is why the hazard falls almost entirely on the poor. Figures from Qadir, Drechsel and Jones, Discover Water, 2025.

Three: not enough water to move the harvest

Even a crop that survives the water risk in the field has to get to a port. In the United States it usually gets there by water, and for four consecutive autumns it has struggled to make this trip.

The USDA’s modal share analysis finds, is that barges carried 44 percent of U.S. grain exports in 2022, 48 percent of all corn, 48 percent of all soybeans, and 32 percent of all wheat.³⁴ That is still close to half of the corn and soybeans this country sells to the world, moving on a river whose depth is now a recurring emergency.

The Mississippi at Memphis set a modern record low of 10.81 feet below normal in October 2022, then broke it at 11.52 feet below normal in October 2023. During the 2023 episode, loading drafts between Cairo, Illinois and the Gulf were cut by an average of 24 percent, tow sizes by 17 to 38 percent, and barge freight rates exceeded 900 percent of tariff, more than nine times the normal baseline rate due to a severe shortage of available barge capacity.³⁵ Low water returned in 2024 and again in 2025, when the Ohio River was contributing just eight percent of Lower Mississippi flow against a typical fifty percent due to a massive flash drought, and southbound grain shipments on the river fell 79 percent in little more than a month with corn movements down 72 percent.³⁶

What a low river actually does to a farmer is measurable to the penny. Peer-reviewed work on the 2022 event found that with the Mississippi gauge at −5 feet, soybean basis fell 58 cents a bushel for farms within five miles of the river, 29 cents at ten miles, and 12 cents at twenty-five.³⁷ The grain is fine. The farmer simply gets less for it, because the only affordable way out of the country has narrowed.

Figure 6. What a river gauge does to a farmer’s cheque. With the Mississippi five feet below normal, the discount on soybeans deepens the closer a farm sits to the river, because the farms nearest the water are the ones with no alternative to it. The grain is unaffected; only its price is. Measured for the 2022 low-water episode by Mitchell and Biram, Applied Economic Perspectives and Policy, 2025.

As of the week ending August 1, 2026, before harvest, before the seasonal low-water window, barge rates at St. Louis were running at 638 percent of tariff, up 39 percent from a year ago. Cairo-to-Memphis rates were up 47 percent.³⁸ The river has not yet made news this year. The price of using it already has.

The Water in the American Basket

Nearly half the contiguous United States, 48.5 percent, was in moderate drought or worse as of August 4, up from 29.9 percent a year earlier.³⁹ The commodity-specific numbers are worse than the map: 50 percent of the winter wheat crop, 58 percent of spring wheat, 57 percent of alfalfa hay, and 49 percent of the national cattle herd are in drought.⁴⁰ USDA’s July estimate put the 2026 wheat crop at 1.536 billion bushels, down 22.6 percent year over year on 5.1 million fewer harvested acres.⁴¹ Corn conditions stand twelve points below last year.⁴² The January cattle inventory of 86.2 million head was the smallest in seventy-five years.⁴³

Against that, the Colorado River. The basin supports 40 million people, seven states and thirty tribal nations, and its natural flow has fallen so far below the volume the 1922 Compact divided that the arithmetic no longer works: inflows averaged 12.9 million acre-feet a year between 2000 and 2024 compared to the baseline of 18 million acre-foot.⁴⁴ Agriculture takes 52 percent of all consumption in the basin and 74 percent of direct human consumption; alfalfa and grass hay alone account for 46 percent of all direct water consumption, and cattle-feed crops for 62 percent of agricultural water.⁴⁵ The Colorado River, in other words, is mostly used to feed livestock.

Figure 7. What the Colorado River actually grows. Feed for cattle takes 62 percent of the river’s direct human use, and a single crop, alfalfa and grass hay, takes 46 percent, nearly twice what every city, factory and business in the basin uses combined. Shares from Richter et al., Communications Earth and Environment, 2024; percentages are of direct human consumption and exclude reservoir evaporation and riparian use.

The seven basin states were given until February 14, 2026 to agree on how to operate the river after the 2007 interim guidelines expired. They failed. The decision therefore passed to the Interior Secretary, and on July 31 the Bureau of Reclamation published its final plan.

It is not a fixed rulebook. Rather than setting operating rules for a decade, it sets a procedure that is rerun every two years between 2027 and 2036, adjusting to how much water is actually in the system. Two numbers do most of the work. The first is how much water Glen Canyon Dam will release from Lake Powell into the lower river each year, which can now be set anywhere between 5.0 and 12.0 million acre-feet depending on how full Powell is in the autumn. The second is how much the states below it must give up: shortages of up to 3.0 million acre-feet.

Where that shortage falls is the fault line. All of it falls on the Lower Basin, Arizona, California and Nevada, and all of it is mandatory. The four Upper Basin states are asked for up to 200,000 acre-feet, and their contribution is voluntary.⁴⁶

The plan is candid about how the water will be found: by paying farmers and irrigation districts to leave fields dry. Combined Lower Basin reductions could eventually reach 3.6 million acre-feet a year: roughly forty percent of what those three states are entitled to draw from the river.⁴⁷

Within the Lower Basin’s share, roughly sixty percent falls on Arizona, thirty-five percent on California and four percent on Nevada.⁴⁸ And the authority behind it is worth being precise about, because these cuts are not the product of a negotiation. The Secretary of the Interior has served as water master of the Lower Colorado since the Boulder Canyon Project Act of 1928 and the Supreme Court’s decree in Arizona v. California, and may set operating rules without the states’ consent when the states cannot agree among themselves. Running underneath this is an older and more mechanical process that is already in force: each August, Reclamation’s 24-Month Study projects Lake Mead’s January elevation and thereby sets the shortage tier that automatically reduces deliveries to Arizona, Nevada and Mexico the following year.⁴⁹ No Record of Decision has yet been signed, which means the post-2026 framework remains a preferred alternative rather than law. Arizona’s water agency has called it “unacceptable,” warning that the reductions “would devastate Arizona’s water users and its economy,” while the Upper Basin governors said they were “encouraged.” Litigation is the widely expected next step.

Two facts about what that water grows. Yuma, Arizona supplies 80 to 90 percent of America’s leafy greens in the winter months. The Imperial Valley, which holds the single largest entitlement on the river, roughly 97 percent of it going to agriculture: produces about two-thirds of the vegetables Americans eat between November and March.⁵⁰ Imperial County’s unemployment rate is around 19 percent, and roughly one job in six there is in agriculture.⁵¹

California’s own groundwater reckoning is running on a parallel track. Two San Joaquin Valley subbasins are under state probation, with pumpers facing $300 per well and $20 per acre-foot; the Public Policy Institute of California projects that between 500,000 and 900,000 acres of valley farmland will come out of production by 2040 depending on how well the state manages the transition, with the worst case costing roughly 50,000 jobs and $4.5 billion in regional GDP.⁵² And the physical consequence of a century of overdraft is already eating the infrastructure built to fix it: the San Joaquin Valley sank an average of nearly an inch a year between 2006 and 2022, a 33-mile stretch of the Friant-Kern Canal lost up to sixty percent of its carrying capacity to subsidence, and after $325 million and eight years spent rebuilding ten miles of it, the ground beneath the new concrete has already dropped another foot: taking back 250 cubic feet per second of the capacity the project restored.⁵³

None of this stays in the West. USDA now forecasts beef and veal prices up 10.7 percent in 2026 and fresh vegetables up 6.8 percent, against 3.1 percent for food overall.⁵⁴ Those are precisely the two categories most exposed to water: beef through a seventy-five-year-low herd with half of it standing in drought, and fresh vegetables through a river that hit its all-time record low last Friday. A collapse in egg prices is currently masking both in the headline index.

And this arrives at American households with less protection than they had a year ago. The 2024 Household Food Security report, published in December 2025, found 13.7 percent of U.S. households, nearly 48 million people, in food-insecure homes, including more than 14 million children.⁵⁵ It was the last such report the government will publish; USDA announced in September 2025 that it was discontinuing a thirty-year annual series, and the Census supplement that fed it was cancelled the same month.⁵⁶ Independent surveys already put the number far higher: the Urban Institute found that nearly one in four American adults, 24.2 percent, lived in a food-insecure household in 2025, and more than one in four working-age adults.⁵⁷ Both figures are defensible; they measure the same condition with different survey machinery, and they disagree by a factor of nearly two. The instrument that would have settled which is closer to the truth no longer exists. Meanwhile the SNAP provisions of the 2025 reconciliation law begin to bite: on October 1, 2026, seven weeks from now, states must absorb 75 percent of SNAP administrative costs, with a share of benefit costs following in 2027, against roughly $200 billion in program reductions over a decade.⁵⁸

“The federal government stopped measuring hunger in the same year it enacted the largest cut to food assistance in the program’s history. You cannot be held accountable for a number that no longer exists.”

The People Who Move, and the People Who Cannot

Water scarcity does not usually produce a photograph. It produces a decision, made at a kitchen table, one household at a time, and the person who makes it is almost never recorded as a climate migrant⁵⁹.

The strongest global evidence is a 2024 study in Nature Climate Change that examined 107,840 migration flows between subnational regions across 72 countries from 1960 to 2016 and found that drought and aridity significantly increase internal migration, most strongly in arid zones, and most strongly of all in rural, agriculture-dependent areas. Within countries, people move from poorer regions to wealthier ones.⁶⁰ The mechanism is not that water disappears. It is that a livelihood does.

For Central America, the link runs through a specific and well-documented channel. A 2023 study in Scientific Reports matched 323,579 people apprehended in family units at the U.S.--Mexico border between 2012 and 2018 against growing-season moisture in the 54 departments of El Salvador, Guatemala and Honduras they came from. Departments that had recently experienced drier-than-average growing seasons sent 70.7 percent more emigrants to the United States. The authors are careful, and so are we: across model specifications, the effect ranged from 8.9 percent to 257 percent, and apprehension data cannot confirm that the households who lost crops are the same people who arrived at the border.⁶¹ But the direction is not seriously in dispute, and the corroborating evidence is strong: when coffee leaf rust destroyed an average of 71 percent of production for affected smallholders in eastern Guatemala, household migration roughly doubled, including in communities with no prior migration tradition.⁶²

In Somalia, the accounting is more direct than almost anywhere. Nearly 62,000 people were displaced by drought between the start of 2026 and April, and three of every four new displacements in Somalia are now drought-related, a 22 percent year-over-year increase, with a further 125,000 projected by mid-year if conditions held.⁶³ The southern Deyr cereal harvest came in 83 percent below its thirty-year average. Some 6.5 million Somalis are projected in crisis-level food insecurity or worse by March, including two million in emergency conditions and 1.84 million acutely malnourished children.⁶⁴

In Iraq, the migration tracking network has recorded 28,379 families, 170,274 people, displaced by drought between 2016 and 2024 across twelve central and southern governorates.⁶⁵ In Iran, the vice president for rural development said in January that of the country’s 69,000 villages, 31,000 now stand deserted, and that a nation which was 70 percent rural in 1976 has inverted entirely.⁶⁶ That figure is cumulative over five decades and water is one cause among several, but it arrives alongside reservoir declines exceeding 70 percent at two of Tehran’s principal sources, and a president who has said publicly that parts of the capital may have to be evacuated and the seat of government relocated.⁶⁷

The most-quoted number in this field is the World Bank’s projection of 216 million internal climate migrants by 2050 across six world regions, with water scarcity explicitly modeled as a driver.⁶⁸ It is worth knowing exactly what that number is: it is the high end of a 44-to-216-million range, produced under a pessimistic scenario combining high emissions with unequal development, published in 2021 and not updated since. The European Commission’s own research service now cautions that migration forecasts of this kind “are indicative at best” and recommends assessing populations’ exposure to climate extremes rather than predicting migrant counts.⁶⁹

What This Publication Cannot Tell You

Advocacy journalism earns its authority by being the first to name its own weak points. Four of them here are load-bearing.

First: drought displacement is systematically undercounted, and we cannot tell you by how much. The Internal Displacement Monitoring Centre, the world’s authoritative counter, only began recording drought as a displacement trigger in 2017. Its 2026 report notes that fewer drought movements were recorded in the Horn of Africa and southern Africa last year, “but that was partly the result of reduced reporting,” and that Iraq’s drought displacement figure fell to a third of the prior year’s “in part the result of less reporting.”⁷⁰ Sudden-onset disasters generate evacuation orders and camp registrations. Drought generates a family that sells its goats, then its tools, then leaves, and gets recorded, if at all, as an economic migrant. A causal analysis of Somalia from 2016 to 2023 found that market food prices, not rainfall, were the dominant proximate driver of movement, which is precisely why the connection to water gets lost in the record.⁷¹

Second: drought is not the leading driver of global hunger, and we will not claim it is. The Global Report on Food Crises for 2026 found 266 million people in 47 countries at crisis-level acute food insecurity or worse. Conflict was the primary driver for 147.4 million of them; extreme weather for 87.5 million, and the weather-driven figure fell year over year.⁷² Every famine the IPC has classified in this decade, Sudan in 2024 and 2025, Gaza in 2025, has been driven by war, not by rain. Water scarcity is a multiplier and a slow strangler. It is not the main killer, and a movement that overstates it will be correctly discredited.

Third: the most famous case in this literature does not hold up as it is usually told. The claim that Syria’s 2006–2010 drought displaced 1.5 million people who then triggered a civil war is the standard example in climate-security writing. The drought was real and was the worst in the instrumental record. But the 1.5 million figure was traced by later researchers to a single official’s remark in a humanitarian news report, most likely describing people affected by rather than displaced by drought; UN and Syrian government estimates put actual drought-related migration at 40,000 to 60,000 families, four to twelve percent of Syria’s urban growth over the period.⁷³ Satellite analysis subsequently showed Syrian croplands recovering quickly after 2009, with only 0.5 percent of previously cultivated land permanently abandoned.⁷⁴ The original authors have since revised their language from “displaced” to “affected” and describe climate as one contributing factor among many.⁷⁵ We cite the drought. We do not cite the war.

Fourth, and most uncomfortable: the poorest people do not migrate. A study of 115 countries across four decades found that in middle-income countries, warming increased both urbanization and emigration, but in poor countries, higher temperatures reduced the probability of migrating, both to cities and abroad, consistent with severe liquidity constraints.⁷⁶ The relationship between climate stress and movement is an inverted U. Above a wealth threshold, a shock mobilizes people. Below it, a shock immobilizes them. The people in the very worst trouble are the ones you will never see at a border, and a systematic review of dryland mobility research found that of 183 empirical studies, only ten addressed involuntary immobility at all.⁷⁷

This has a mirror image inside the United States that ought to be said plainly. American irrigators facing Colorado River cuts are being paid to fallow: hundreds of dollars an acre-foot, funded federally.⁷⁸ There is no evidence of population collapse in Colorado River farming counties, and we will not invent it. What the American case actually demonstrates is that a rich country can buy its way out of the displacement that a poor country has to live through. That is a more damning fact than a depopulation statistic would have been, and it is true.

“The question is never whether a society can survive losing its water. It is whether that society can afford to be paid for losing it.”

The Window That Is Still Open

Groundwater is the slowest-moving crisis in the food system, which means it is also the one where action taken this year still changes the outcome. Four things are required.

First, treat water accounting as food security infrastructure. The most recent aquifer-wide USGS assessment of the Ogallala reports water levels as of 2019. Anyone citing “the latest federal data” on the aquifer that irrigates the American grain belt is citing measurements seven years old. Meanwhile USDA has terminated the thirty-year household food security series.⁷⁹ A country that intends to manage a resource has to measure it: fund the USGS groundwater monitoring network, restore the food security survey, and require the states drawing on interstate aquifers to publish annual, well-level data.

Second, pay for demand reduction before the well fails, not after. The foundational Kansas projection found that cutting groundwater use twenty percent today would extend the region’s peak agricultural production into the 2070s and yield more cumulative output beyond 2070 than continuing at current rates.⁸⁰ Kansas’s Local Enhanced Management Areas have already demonstrated the mechanism at small scale: one district cut applied water per acre by 34 percent primarily by reducing water intensity rather than idling acres, and the Greater GMD4 LEMA is in renewal hearings right now, with the next order due for the 2028–2032 term.⁸¹ Conservation is not a sacrifice of production. On the arithmetic, it is the only path that preserves production.

Third, make anticipatory financing the default for slow-onset water crises. Somalia’s 2026 displacement was forecast months before it happened; the Deyr harvest failure was visible in satellite data before the harvest. Anticipatory action: cash, seed, drought-tolerant inputs and pre-positioned food released on forecast triggers rather than on famine declarations: costs a fraction of late emergency response. It requires a humanitarian budget that exists. The U.S. contribution has fallen from roughly $14 billion to $3.7 billion in a single year, and no trigger system survives the removal of the money behind it.⁸²

Fourth, protect the domestic floor while the price wave arrives. Beef at nearly eleven percent and fresh vegetables at nearly seven percent are water prices, arriving in American grocery stores through the Colorado River and the drought map. The SNAP cost-shifts that begin on October 1 will transfer part of that cost onto state budgets and, from 2027, onto the households least able to carry it.⁸³ A Farm Bill built for volatility: insurance and disaster programs that reach diversified operations and pay in the season the loss occurs, not two years later: is the other half of the same obligation.

How to Watch It Come

Every figure in this article came from a public dataset. If you want to watch the water yourself:

· The American drought, weekly: the U.S. Drought Monitor updates every Thursday; NIDIS’s drought.gov carries current conditions and the Mississippi River dashboard.

· The Colorado River, daily: Reclamation publishes Lower Colorado reservoir levels every day and the 24-Month Study monthly; the post-2026 process page holds the Final EIS.

· The aquifers: USGS groundwater monitoring; the Kansas Geological Survey annual water-level measurements; India’s Central Ground Water Board assessments.

· The crops and the freight: USDA’s Crop Progress, the monthly WASDE, the weekly Grain Transportation Report, and the GEOGLAM Crop Monitor.

· The hunger and the displacement: FEWS NET, IPC, WFP’s HungerMap Live, and IDMC’s Global Internal Displacement Database.

A Ledger That Comes Due

Water is the only input in agriculture with no substitute. A farmer who cannot afford fertilizer grows a smaller crop. A farmer who cannot afford diesel harvests late. A farmer with no water grows nothing, and no amount of capital, technology or policy will change that arithmetic.

For most of the last seventy years the world has hidden that fact from itself by borrowing. It pumped aquifers faster than rain could refill them, built cities and export industries on the difference, and recorded the resulting harvests as productivity rather than as debt. Seventy percent of the world’s major aquifers are now in decline. The lake behind Hoover Dam is one-quarter full. The wheat belt of the southern Plains is farming on fifty feet of saturated sand. Punjab is pumping half again more groundwater each year than its aquifers can sustainably yield.

The people who will pay are not the people who spent it. The pastoralist in Somalia whose Deyr harvest came in 83 percent short did not drain an aquifer. The Guatemalan smallholder whose growing season failed did not build a diversion canal. The mother in Phoenix looking at the price of ground beef, and the farmworker in the Imperial Valley whose employer has just been paid to leave a field dry, did not sign the 1922 Compact. But all of them are standing downstream of the same ledger, and it is coming due in the currency it always comes due in: skipped meals, sold livestock, mounting debt, a decision made at a kitchen table about whether to stay.

What makes this crisis different from a drought or a strait or an El Niño is that it does not surprise anyone. Aquifer decline is measured in monitoring wells, published in federal reports, and projected decades in advance. There will be no moment at which the world can say it did not know. There is only the question of whether the people who hold the water rights, write the farm bills, fund the humanitarian budgets and set the pumping limits will act while acting is still cheap.

Call your representatives, in your statehouse and in Washington. Ask them three questions: what is being done to measure the aquifer your food comes from, what is being done to reduce the draw on it before the wells fail, and what happens to the families who cannot afford to leave when they do. Then ask them again in October, when the SNAP cost-shift takes effect, and again in January, when the Colorado River framework begins. The water is being spent now. So is the time.

12. The mechanism: aquifer sands are separated by fine-grained clay and silt layers, or aquitards, whose pore water helps carry the weight of everything above. Withdraw the water faster than it is replaced and that support is lost; the fine layers compact, the ground surface drops, and where compaction is inelastic the aquifer’s storage capacity is destroyed rather than merely emptied.

17. Sirorattanakul, K. & Avouac, J-P. (2026), Science Advances, March 25, 2026, DOI 10.1126/sciadv.adz5711: seismicity in northern California increases by up to roughly 10 percent in association with groundwater changes, peaking about half a month after the peak change.

HiQuake, the Human-Induced Earthquake Database, Durham University (1,377 cases as of December 2025): hydraulic fracturing 31 percent, mining 25 percent, reservoir impoundment 17 percent, conventional oil and gas 11 percent, groundwater extraction 0.9 percent. https://inducedearthquakes.org/. The database’s compilers note that it includes proposed cases “without regard to the strength of the case made,” so the groundwater share is if anything generous. On the Groningen bound: Boitz, N. et al. (2024), Nature Communications 15: 329, DOI 10.1038/s41467-023-44485-4, roughly 28 MPa of pore-pressure depletion produced a maximum event of ML 3.6, and the authors put the maximum possible induced magnitude at around Mw 4.

19. Oklahoma magnitude-3-and-above events rose from a background of one to two a year before 2009 to 888 in 2015; the largest was the Mw 5.8 Pawnee earthquake of September 3, 2016. The cause is wastewater disposal rather than hydraulic fracturing: USGS states that “only 1-2% of the earthquakes can be linked to hydraulic fracturing operations” and that over 90 percent of injected wastewater is a byproduct of oil extraction. Rates have since fallen close to historical levels following mandated plug-backs and volume limits.

(2024), “Stem traits promote wheat climate-resilience,” Frontiers in Plant Science 15: 1388881, DOI 10.3389/fpls.2024.1388881: stem reserves of water-soluble carbohydrate contribute roughly 10 to 40 percent of final grain weight in favourable conditions, rising to 40 to 70 percent under stress, with remobilisation elevated under terminal drought, the plant drawing down savings because current photosynthesis has failed. The elevator discount for shrivelled grain and low test weight is a matter of grain-grading practice rather than of published research; test weight is a grade-determining factor in the U.S. wheat and corn standards administered by USDA’s Federal Grain Inspection Service.

DOI 10.1038/s41467-025-67862-7. Modeling uses a process-based crop model within an Earth system model under SSP2-4.5 across four ESMs. The frequently quoted “3.6 percent” figure is the maximum for soybean alone, not a combined-staple global loss.

24. The mechanism is osmotic before it is toxic: dissolved salts lower the water potential of the soil solution, so a root must generate more suction to draw water than it can produce, and the plant experiences physiological drought in visibly wet soil. Sodium and chloride ion toxicity and induced nutrient deficiency follow. FAO and the Intergovernmental Technical Panel on Soils, Soil Salinization as a Global Major Challenge (Soil Letter No. 3, 2021), https://www.fao.org/global-soil-partnership/resources/highlights/detail/en/c/1412475/

25. Reclaiming a salinised field requires applying water beyond the crop’s needs so that the excess percolates through the root zone carrying dissolved salts with it, the leaching requirement, together with functioning subsurface drainage to remove that water; without drainage, leaching raises the water table and returns the salt by capillary rise. Both are standard irrigation-management practice and both are water-intensive. FAO Irrigation and Drainage Paper 29, Water Quality for Agriculture (Ayers & Westcot), and FAO, Global Status of Salt-Affected Soils (2024).

Note: this assessment supersedes the widely circulated figure of 1.1 billion hectares.

The figure is in 2013 dollars and covers lost crop production only; infrastructure damage, health effects, land abandonment and lost farm employment have never been priced globally. FAO’s Global Status of Salt-Affected Soils (2024) contains no economic figure, and FAO’s Global Soil Partnership still quotes the 2014 estimate. The calorie figure is Russ, J. et al. (2020), Salt of the Earth, World Bank Policy Research Working Paper 9144, a working paper, not peer-reviewed. Note that the widely quoted claim that 2,000 hectares are lost to salt daily is not independent corroboration: it is the press release for the same 2014 study, the same arithmetic of $441 per hectare across 62 million hectares, describing an average over 1990–2013 rather than a current rate.

28. Drechsel, P., Bartram, J., Qadir, M. & Medlicott, K. (2024), npj Clean Water 7: 67, restating Thebo, A.L. et al. (2017), Environmental Research Letters 12(7): 074008, DOI 10.1088/1748-9326/aa75d1. An important qualification: these are modelled proximity-and-dilution estimates that include indirect use, a farmer pumping from a river carrying a city’s discharge, not a census of deliberate sewage irrigation. No global burden-of-disease estimate for wastewater irrigation exists, and the widely repeated figure of “200 million farmers” has no traceable primary source; neither is used here.

29. Qadir, M., Drechsel, P. & Jones, E.R. (2025), Discover Water 5: 74, reporting 2023 data: 267.5 billion cubic metres of municipal wastewater generated globally, 54.7 percent treated and 45.3 percent discharged untreated. By income group the treated shares are 91.5 percent (high income), 48.0 percent (upper-middle), 29.4 percent (lower-middle) and 5.8 percent (low income); sub-Saharan Africa stands at 17.2 percent. Only 37 of 231 countries report agricultural reuse at all.

30. Amoah, I.D. et al. (2016), PLOS Neglected Tropical Diseases 10(12): e0005161. Wet-season Ascaris prevalence among wastewater-irrigating farmers in Kumasi was 15.77 percent against 6.00 percent in matched controls (odds ratio 3.99, 95% CI 1.15–13.86). The corresponding hookworm comparison (12.73 versus 2.00 percent) did not reach significance, and dry-season hookworm showed no excess; this publication cites the Ascaris result only. A frequently quoted pooled odds ratio of 5.49 from a later review conflicts with the primary data, including its own co-author’s, and is not used.

31. Shuval, H. (1993), Water Science and Technology 27(3–4): 167. Some 13,500 hectares of salad crops around Santiago were irrigated with raw sewage; typhoid incidence peaked at 210 cases per 100,000 in 1977 and again in 1982, and Salmonella typhi and Vibrio cholerae were both isolated from irrigation canals. In the April 1991 cholera outbreak, 68 percent of the first 41 cases had eaten raw wastewater-irrigated salad vegetables. Chile prohibited the practice and incidence fell.

32. Soil metal enrichment after roughly 90 to 100 years of untreated wastewater irrigation in the Mezquital Valley: Ziegler Rivera, F.R.A. et al. (2023), reporting chromium 7.7 to 8.6 times and cadmium 3.0 to 4.7 times background. On antimicrobial resistance and pharmaceutical residues in the same soils: Heyde, B.J. et al. (2025), npj Clean Water 8: 6, reporting sul1 resistance-gene abundance roughly two orders of magnitude higher in wastewater-irrigated soil, together with triclosan at 5.7–16.7 mg/kg and carbamazepine at 3.5–7.0 mg/kg.

33. On Israel: World Bank (2017, using 2015 data), 87 percent of treated effluent reused, roughly half of national irrigation water, priced at $0.22–0.34 per cubic metre against $0.66 for fresh water. Higher figures circulate, EPA says “nearly 90 percent,” Qadir et al. (2025) say 99, and this publication uses the World Bank number with its year attached. On the nutrient value and the Mezquital farmers’ objection to the Atotonilco treatment plant: Heyde et al. (2025), as above, valuing the nitrogen at US$179–451 per hectare per year, with nitrogen use efficiency of about 65 percent against under 50 for synthetic fertiliser, and soil carbon roughly 1.5 times higher after forty years.

The characterization of this as the smallest inventory since 1951 is a reading of the NASS historical series by trade analysts; NASS’s own release does not use that framing. The July 1, 2026 report put all cattle and calves at 94.2 million, with beef cows down 1 percent year over year and replacement heifers up 1 percent: early, fragile signs of herd rebuilding that further tighten near-term beef supply.

For 2027–2028 the framework assumes a 1.5 maf Lower Basin shortage, with cuts of 760,000 AF (Arizona), 440,000 AF (California) and 50,000 AF (Nevada).

48. Allocation of Lower Basin reductions (approximately 60 percent Arizona, 35 percent California, 4 percent Nevada), the October 1, 2026 effective date, and state reactions: Deseret News, “Winners and losers of the Interior Department’s Colorado River water proposal,” August 5, 2026, https://www.deseret.com/politics/2026/08/05/winners-and-losers-of-interior-departments-colorado-river-water-proposal-federal-cuts-to-arizona-and-lower-basin-water-use/. Note an unresolved discrepancy this publication has not been able to settle: reporting on the Final EIS gives the framework an October 1, 2026 effective date, coinciding with the expiry of the current guidelines, while legal analyses of the same document describe implementation beginning January 1, 2027. Readers should treat the precise commencement date as unsettled pending the Record of Decision.

49. The Secretary of the Interior’s role as water master of the Lower Colorado River derives from the Boulder Canyon Project Act of 1928 and the Supreme Court’s decree in Arizona v. California, 376 U.S. 340 (1964), under which the Secretary contracts for and delivers all mainstream water below Lee Ferry. The annual shortage-tier mechanism operates under the 2007 Interim Guidelines and the 2019 Drought Contingency Plan: Reclamation’s August 24-Month Study projects Lake Mead’s January 1 elevation, which determines the shortage tier and the resulting delivery reductions for the following calendar year. As of this writing Reclamation had published the Final EIS but had not signed a Record of Decision.

The divergence from USDA is not a denominator effect; USDA’s own adult-level rate is roughly 13 percent, close to its household rate. It is a survey-mode effect: the Urban survey is self-administered on a probability-based panel (Ipsos KnowledgePanel, address-recruited, including households without internet), lacks the Current Population Survey’s income screener, and respondents report food hardship more readily without an interviewer present. Neither Feeding America nor food-bank surveys support a national one-in-four adult figure: Map the Meal Gap 2025 reports 14.3 percent of individuals and is a downscaling model of the federal data, not an independent survey; the Greater Boston Food Bank’s April 2026 report finds 40 percent of Massachusetts households food insecure, a state figure, and a household one.

59. This is a claim about the record, and it is documented. The Internal Displacement Monitoring Centre began recording drought as a displacement trigger only in 2017, and attributes recent year-on-year declines in recorded drought displacement partly to reduced reporting rather than reduced displacement. Sudden-onset disasters generate evacuation orders and camp registrations; drought generates a household that sells its assets and leaves, recorded, if at all, as an economic migrant.

A flash drought in 2012 dried out soil, harming crops in Kansas and several other states. John Moore/Getty ImagesThe Crop Hazard That Skips the Forecast

The last time this publication described a climate driver reshaping the world’s food supply, the story was measured in months. In Scorched Harvest, we wrote about an El Niño building in the tropical Pacific on what we called a twelve-month fuse: a slow, hemisphere-spanning reorganization of where rain falls, its worst harvest failures a year out. Extreme heat is the opposite kind of threat. It gives no fuse, no warning at all.

2024 was the hottest year in the instrumental record, the first full calendar year more than 1.5°C above the pre-industrial baseline, and the capstone of the hottest ten-year stretch ever measured in the history of humankind.¹ 2025 came in second or third (depending on how temperatures around the world are measured), cooler than 2024 only in the sense that one burning furnace runs slightly cooler than another. The rolling three-year average has now crossed 1.5°C for the first time, and the heat waves that swept Europe, Asia, and North America were, by the reckoning of the scientists who study them, the deadliest weather events of the year and, in several cases, roughly ten times more likely than they would have been only a decade ago.² A single European summer put land temperatures past 46°C on the Iberian Peninsula and is estimated to have killed on the order of sixteen thousand people.³

The temptation will be to file this under weather. File it instead under food, and under the speed at which that whole crops can now be lost.

Drought creeps. Floods arrive and recede. An El Niño telegraphs its intentions half a year in advance. Heat is the driver that collapses the warning window to nothing, and just as importantly, it does its damage not at one stage of food production but at every stage at once: in germination, in flowering, in the field as it grows, in the barn, in the soil, in the river, and, on a lag of a single growing season, in prices of the food on your grocer’s shelf.

“A drought you can see coming for months. A heat wave you can see coming only for days. By the time you can feel it, the pollen is already dead, the milk has already stopped, and the forecast of food production for the season has already dropped precipitously.”

The Season That Fails Before It Begins

Every impact to grains that follows, begins with a seed. Heat can reach the crop before the crop even exists. A seed is a living thing running on a slow clock, and the warmth of the new season winds that clock forward toward its birth and growth. The relationship is regular enough that seed scientists have reduced it to a “rule of thumb” nearly a lifetime ago: Within ordinary limits, a seed’s viable life is cut roughly in half for every one per cent rise in its moisture content and then halved for every ten degrees Fahrenheit of storage heat above normal.⁴ The seed held over for next season’s planting does not wait patiently in a warm storeroom. When exposed to high heat before it is planted, the seed ages in fast-forward, its reserves burning down through accelerated respiration and the oxidation of its own oils, until, when it finally goes into the ground, there may be too little of it left for it to wake. It is the same ten-degree arithmetic that will later govern the grain in the storehouse (Figure 5): heat halves the usable life of the seed at the start of the season and then dictates how long grains can be stored at the end of the harvest.

“A seed kept too warm is a seed already spending itself and reducing its viability. By planting time, if too much of it has already been used up a seed may not be able to bring forth a live plant.”

If seeds have been exposed to too much moisture or too high a temperature, the loss shows in the field as thin growth and patchy gaps that a farmer must either replant, at cost and delay, or simply accept as a smaller crop. This loss occurs due to excessive heat even before the first leaf has unrolled. The seed’s ordeal is not confined to the storage bin. Too much heat during the weeks that a seed ripens in the Fall on the mother plant, can leave it weak and short-lived even before it is ever gathered as seed. Drying the seeds after they are harvested at too high a temperature does further, invisible harm. The next risk is that if there is too much heat in the Spring at the time of germination, germination itself can falter in soil that is too hot or too dry, precisely the ground conditions that a heat wave creates.⁵

For a commercial grower, heat impact to seed production through germination is merely a cost and an aggravation, absorbed in part by paying a higher price for a certified seed bought fresh each year. For the many millions of smallholders who save their own seeds and keep them in whatever warmth the season provides, with no cold room and no dehumidifier, the seeds are at risk. The hotter the year, the less of their saved seeds survive to plant the next season. This means that a punishing season leads to a smaller harvest and also reduces the viability of the very seed needed to be used to begin the recovery the next year. Heat, in other words, does not wait for a crop to grow before it begins subtracting from it. It is already at work in the seed bag, and the season can be diminished before the seeds are ever sown.

Figure 1. Warm storage runs the seed’s clock down. Germination remaining after prolonged storage falls sharply as storage temperature rises, so seed held over in a hot storage container loses much of its viability before it is ever planted. The same ~10°F rule that governs the grain in the bin (Figure 5) applies to how many seeds will be viable. The curve is illustrative, anchored to reported rice-storage trials.

Every Agricultural Crop Has a Fertilization Number at Risk in a Heat Dome

Start with the grains, because the grains are the least forgiving part of our food system. Every staple cereal has a temperature above which its reproduction simply fails, and those numbers are lower, and closer to being exceeded, than most people who eat the grain in a bowl of cereal, in bread, in pasta, in a rice bowl or on a cob of corn will ever guess. We truly were in a “Goldilocks” climate before we started burning fossil fuels and emitting CO₂ into the atmosphere.

For the three crops that feed most of humanity, agronomists have measured the critical thresholds for seed set at flowering with unsettling precision: roughly 37.2°C for rice, 37.9°C for maize and just 27.3°C for wheat.⁶ When agronomists talk about “seed set at flowering,” they are specifically looking at the critical pollination window when the crop blooms. During this short phase, if temperature thresholds are exceeded, the extreme heat damages the flower’s delicate reproductive organs rendering pollen sterile or preventing fertilization.

Read the wheat number in that figure again. Wheat, the crop the temperate world treats as its dependable staple, begins to lose fertility at a temperature that a spring afternoon now routinely surpasses in Kansas, Punjab, or the Australian wheat belt. Rice yields begin sliding once the season sits above about 33°C.⁶

What happens to crop production above those set temperatures is not a gentle taper. Flowering is the crop’s single most heat-sensitive hours or days, and heat sabotages fertilization mechanically: it dries and closes the flower, it kills or sterilizes the pollen, it arrests the pollen tube before it can reach the ovule. In maize, the most heat-vulnerable of the three, only a few hot days landing precisely when pollen is going down the silk to the kernels can stall pollen-tube growth and abort kernels wholesale, so that an ear which looked healthy in July fills only halfway by September.⁷ Almost everyone has peeled the husks off an ear of corn only to find many kernels have not filled out. The cruelty of it is the timing: a crop can be perfectly watered, perfectly fertilized, and still be rendered barren by a two-day heat spike that happens to coincide with the wrong week of the life of the wheat, rice or corn plant. The grain is not lost to scarcity of anything. It is solely lost to a thermometer reading above its critical threshold.

Figure 2. Every crop has a number. The air temperature at which seed set fails during flowering (27.3°C for wheat, 37.2°C for rice, 37.9°C for maize) set against the 40°C afternoons a modern heat wave now clears routinely. Solid bars mark viable temperature; hatched zones, sterility. Thresholds from the reproductive-stage heat-tolerance literature.

Interfering with reproduction is not the only way heat causes dramatic crop loss. The heat wave does not need to come during the fertilization period to steal the vitality of the grains. Heat also cuts into crop yield in three slower ways that are just as devastating and just as predictable.

1) The first is haste. Grain fills the corn, rice and wheat kernels during a fixed window between flowering and maturity, and a plant that is exposed to high temperatures that speeds up its growth processes is a plant that matures too fast: high temperatures accelerate development, shorten that grain-fill window, and rush the crop to a premature, lightweight maturity. Exposed to excess heat, the plant checks every growth hallmark on the calendar but still delivers less, because it spent fewer days pouring starch into each kernel. A field that looks like it ripened early did not ripen. It surrendered.

2) The second is thirst, not the crops being thirsty, but the atmosphere and soil’s thirst. Every degree of additional heat widens the vapor-pressure deficit, the gap between how much moisture the air can hold and how much it actually does hold, and that gap is the engine that pulls water out of soil and the plants’ leaves. This is why a heat wave can hollow out a harvest even where the rain gauge reads normal. The rain fell; but the heat simply took back the rain before the roots could use it, evaporating soil moisture and forcing the plant to close its pores and stop growing to keep from desiccating. Rainfall near average is no defense against an atmosphere that is poised to evaporate soil moisture faster than the rain can fall.

3) The third is the water demand that no one can create out of thin air. Extreme heat drives irrigation demand to its annual peak at the exact moment water is already being drawn down from the reservoirs, aquifers, rivers, and snowpack that irrigation depends on. Demand spikes hit as supply falls, and the two curves cross at the worst possible time which causes the farmer with a well or a pump to discover that due to the excess heat, the season now asks for more water than the snowfall, landscape and aquifer have to give.

The preview to the damage extreme heat can cause is already on the record. Europe’s farm sector has been losing an estimated €28 billion a year to extreme weather, only a fraction of it insured, and the summer of 2025 alone extreme heat reportedly damaged a large share of France’s corn crop, took roughly half of some regions’ carrots, and killed poultry by the flock.^{8 9}

The record has a human face. In Punjab, Gurjinder Singh watched the March heat of 2022 rush his wheat to a premature, hollow ripeness; his land, which normally gives 23 to 25 quintals an acre, yielded 14 to 15, what he called “a substantial 40 percent loss.”¹⁰

The Flash Droughts That Destroy a Crop in a Fortnight

There is now a name for the fast version of what the last section described, and it belongs almost entirely to the vocabulary of this century. Scientists call it a “flash drought.” This is something different from the slow, seasonal deficit that creeps across a landscape over years. A flash drought is a drought that ignites and matures in the space of a few weeks, when a run of extreme heat, wind, and cloudless sun drives the atmosphere’s thirst so high that it pulls moisture from the soil faster than normal rain can replace it. The term only was coined in 2002, and for a decade it sat as a specialist’s curiosity; monitoring it now means watching not the rain gauge but the rate at which the air is drying, a jump of half again in evaporative demand over two weeks is enough to declare one.¹¹

The fast droughts appear to be winning and being the prominent kind of drought. The first global study to settle the question, published in Science in 2023, found that over the past sixty-four years droughts have begun to intensify measurably faster across nearly three-quarters of the world’s land regions, with a clear statistical shift from the slow-onset kind of drought toward the flash kind, a transition the authors trace directly to human-caused warming, through the very amplification of evaporation and rainfall deficits that a hotter atmosphere produces. The slowest of the old climate disasters is learning to sprint. The acceleration is sharpest over Europe, northern and eastern Asia, the Sahel, and the western coast of South America, and it is projected to spread across most of the planet’s land if warming continues.¹² The old kind of drought is still happening as well.

“A slow drought is a thing you watch approach for a season. A flash drought is a thing you discover has already happened in a matter of weeks.”

The bill for a drought that moves this fast is steep, precisely because speed removes the time in which anyone might have adapted. The 2012 event that first seized the country’s attention carved more than thirty billion dollars from the American economy in a single summer; a 2017 flash drought across the Dakotas and Montana took an estimated $2.6 billion from agriculture alone, and the frequency of flash droughts is set to climb. On the high-emissions path, the annual risk of flash drought on North American cropland is projected to rise from roughly a third today to about half by the end of the century, and the increases are projected to be higher still in Europe.¹³

These are not projections waiting on the future; the events are already arriving in series. In June 2023 a flash drought spread across the U.S. Midwest until it covered close to two-thirds of the nation’s corn, catching the crop just as it entered pollination; by that October the Mississippi River had fallen to record-low stages, halting barge traffic and drawing saltwater upstream into the drinking water of southern Louisiana. That same autumn a second flash drought seized the Southeast, wilting newly planted wheat, rye, and hay and forcing so many ranchers onto bought feed that the USDA paid its largest livestock-forage disaster relief on record, concentrated in Mississippi, Tennessee, and Alabama. The following summer heat settled over the mid-Atlantic, the rain stopped, and corn from the Carolinas to Pennsylvania shriveled in a matter of weeks.¹⁴

Each of these droughts matured too quickly for the farmers to do anything to prepare, which is the whole of the danger. The speed and regional impacts of these droughts are the reason flash droughts belong at the center of this account rather than its margins. It is heat’s signature written into the water cycle itself: the same argument as every section before it, arriving from a different direction. The hazard that once granted a season’s warning now grants only a fortnight to prepare.

Behind the numbers are the people who watched it happen. Greg Lee, a North Dakota farmer who had worked the same ground for forty years, lived through that 2017 Northern Plains flash drought; asked what it did to his fields, he put it in one flat sentence: “The crops just didn’t come out of the ground.”¹⁵

Figure 3. The drought that moves at heat-speed. A conventional drought lowers soil moisture to drought levels over a season or more; a flash drought, driven by extreme heat and evaporative demand, can do it in two to four weeks, collapsing the window in which a farmer might respond. The curves are a schematic of the two onset regimes; one gives no chance of survival.

Animals Cannot Sweat Off Extreme Heat When It Comes

Then there is what happens in the barn, where heat is a matter of animals in distress.

A dairy cow is a walking furnace: a high-producing animal generates enormous metabolic heat, and unlike a human, a cow sweats at only about a tenth the rate, far too little to shed the heat it makes. Cows begin to suffer heat stress at temperatures that feel merely warm to the people milking them. The cows that produce the greatest amount of milk can begin to experience reduced milk production if temperatures in the barn reach even the mid-60s Fahrenheit (17-19 degrees Celsius). As the combined heat-and-humidity load climbs, cows will eat less, stand more, and give less milk. Mild heat stress alone can cut milk by a couple of pounds per cow per day; a hard summer with weeks of high heat can pull daily yields down by double digits.^{16 17} If the heat-humidity index in the barn is raised past the high 80s Fahrenheit for even several hours, with no cool night for the cows to recover in, vulnerable milking cows do not merely produce less, they die, in the barn, in the feedlot and in the pasture, too.¹⁸

The losses are not hypothetical and not small. Heat stress already costs U.S. livestock producers on the order of $2.9 billion a year in today’s dollars, the majority of the losses borne by the dairy industry.¹⁷ A heat wave, in other words, does not wait for the harvest to translate itself into less food, it takes the milk that afternoon and it takes the beef of the cow later that week if the high temperatures hold. The heat wave that enveloped northern India in 2022 reportedly cut milk output by as much as 15 percent at the same time it reduced wheat yields by anywhere from a tenth to a third across several Indian states. A single excess heat event depletes the food system at both ends at once.⁸The same arithmetic runs in American barns. In Fremont, Wisconsin, Jacob Hoewisch, who milks a fifth-generation herd, loses three to ten pounds of milk from each cow on the hottest days, and watches the heat reach past the milk to the animal itself: a cow whose “body overheated for too long of a period”, he says, can lose the calf she is carrying.¹⁹

Figure 4. The animals cannot sweat it off. Milk yield falls as the temperature - humidity index climbs, well before the barn feels dangerous to the people in it, and above roughly THI 84, with no cool night to recover in, vulnerable cattle begin to die. The curve is illustrative of the measured response; anchor values are drawn from dairy-science field studies.

The barn is not only a dairy barn. Birds have no sweat glands at all; they shed heat only by panting, and a fast-growing broiler runs so hot inside that a single bad afternoon can kill it. Chickens, turkeys, and ducks are all exposed, and turkeys, the largest of the three, are among the most heat-fragile birds on any farm; ducks cope only where they can reach the water, they use to cool themselves. When a heat wave swept France in the summer of 2026, poultry sheds turned into ovens and birds died by the million, with turkeys taking the heaviest toll. It was not the first time. A comparable heat wave in 2003 killed an estimated four to five million French chickens and turkeys, about two percent of the national flock.²⁰ Sheep and goats aren’t much better off, because they cool by panting instead of sweating, and heat and drought wipe out both their grazing pastures and the lamb and kid crop that herding families in the Global South live on. Because chicken is now the most-eaten meat on Earth, a bird engineered to fatten fast and left without any way to sweat sits close to the center of the food supply, not at its edge.

The Harvest Lost After the Harvest

Every section so far has followed heat into the field and the barn and then stopped at the moment of harvest, as though a crop once cut was a crop secured. It is not. Heat keeps working on food after it leaves the ground, and the losses it inflicts in the bin, the barn, and the cold chain are large, accelerating, and almost entirely absent from the public conversation about climate and hunger.

Begin in the grain bin, where a harvest is supposed to be safe. Stored grain is not inert; it breathes, and warm, damp grain breathes hard, generating its own heat and moisture until pockets of it form “hot spots” that bloom with mold, draw insects, and cake into spoiled, unsellable crust. The governing rule is unforgiving: for every roughly ten degrees Fahrenheit that grain temperature rises, the safe storage time is cut about in half.²¹ It is the very rule that governs the viability of the seed at the other end of the season, too (Figure 1). Insects that lie dormant in cool grain breed freely between 70 and 90°F, precisely the range a warming climate now delivers for much of the year. The mold that follows does not merely reduce weight; it strips nutritional value and, worse, can leave behind mycotoxins, and mycotoxins, once formed, are heat-stable, surviving the milling and cooking that kill the fungus that made them.²¹

The most dangerous of those toxins is now migrating with the heat. Aflatoxin, the most acutely toxic and most tightly regulated of the mycotoxins, and a known liver carcinogen, is made by a fungus that flourishes on heat- and drought-stressed crops in the field and on warm, humid grain in storage. For most of history it was a problem of the tropics and the American South. That is changing: a landmark 2016 study projected that just two degrees of warming, a level now expected between roughly 2030 and 2050 rather than in some distant future, would make aflatoxin a genuine food-safety problem in European maize, driving its contamination index up more than ninety per cent and pushing its range northward into countries that had never had to reckon with it.²² The projection is now being met by observation. Aflatoxin-producing fungi, once rare in temperate Europe, are established across the south and center of the European continent; and a 2026 analysis of more than seventeen thousand samples in China found contamination measurably higher than a decade earlier, with temperature alone explaining nearly half of the increase.²²

The barn tells the same story in a different crop. Hay baled even slightly too wet when baled or stored is a constant hazard when heat and humidity compress the drying window, the hay begins within days to mold and ferment, its sugars and proteins are consumed by microbes and locked, through the browning of the Maillard reaction, into forms livestock cannot digest. A bale of hay can shed much of its feed value while still smelling sweet. Push the internal temperature past about 170°F, as dense wet bales can, and the same microbial heat that spoils the forage causes spontaneous combustion and sets the barn on fire.²³ Rice, the staple of half the planet, most of it warehoused in the hottest, most humid corners of the world, deteriorates faster the warmer it is held, turning rancid, yellowing, shedding milling yield and cooking quality, and, above about sixteen per cent moisture, growing the very molds that make aflatoxin.²⁴

Then there is everything that must stay cold. Roughly a third of all the food the world produces is already lost or wasted, and about a seventh of it has gone bad before it ever reaches a retailer and much of that for want of refrigeration that a hotter climate makes necessary.²⁵ Meat, dairy, fish, and fresh produce spoil in hours, not weeks, when a heat wave overwhelms a cold chain, or when the refrigeration or the power that runs it fails for any reason. Without refrigeration, warmth speeds the bacteria that turn spoiled food dangerous and is a driver behind hundreds of thousands of deaths from foodborne illness each year.

The newest evidence closes the loop, identifying the rest of the crop losses caused by climate-driven heat. A 2026 study found that heat stress raises the share of the crop lost at the moment of harvest itself, a direct climate channel into food loss that had simply gone unmeasured.²⁵ It was the first study to show, with data, that high temperatures sharply increase food loss during harvest, finding that heat-induced losses are three to four times greater in manual than in mechanical harvesting. This means smallholder farms across the Global South are at greatest risk of crop spoilage during a hot harvest.

None of this shows up in a yield statistic. A crop can be grown, survive the flowering heat and the flash drought and the exhausted river, be cut and counted as a good harvest and still be halved while it is being transported to market and sold to people who need food, by the same warmth that menaced the crop in the field. It is the last stage heat attacks, and the most invisible, and it arrives at the same counter, in the same currency, as all the rest of the attacks heat mounts on food production around the world.

Figure 5. Every ten degrees halves the storage time. Grain in storage is not inert; it self-heats, and the time it can be held safely falls by roughly half for each ~10°F rise in grain temperature, so a hot summer bin turns a season’s reserve toward spoilage far faster than a cool one; this is the same clock that governs seed viability at planting (Figure 1). The curve is a schematic of that rule of thumb.

Why Heat is Different Than Other Climate Shocks

Put the pieces together and the argument writes itself. Heat is not one hazard on a list of climate hazards. It is the master variable, the climate driver that attacks the field, the soil, the water, and the animals over wide areas simultaneously, and does it faster than any warning system was built to detect and sound the alarm.

Consider what separates heat from every other climate shock this 4Hunger.org tracks. The fertilizer crisis we documented in Fertilizer Famine moves on a one-season lag. The American megadrought in Parched Ground took many years to form. The El Niño in Scorched Harvest announces itself half a year ahead with the worst impacts predicted a year in advance. Every one of those is a slow emergency you can, in principle, prepare for.

Heat is the fastest climate impact. The pollen in wheat, corn and rice can die within hours if heat hits during the days when the flower is open. The production of milk drops in cows the same week the barn overheats. The soil gives up its moisture across a single scorching fortnight. There is no season of grace between the forecast of heat domes and the loss, because for a crop at flowering, or at other stages of growth, the forecast of extreme heat can become an unstoppable loss.

That speed is precisely why heat has become the biggest climate driver of agricultural loss right now. In a food system already stripped of its buffers, with reserves drawn down, fertilizer in short supply, and with the American food production shock absorber running on empty, the hazard that can erase a harvest in an afternoon is the one the world is least equipped to catch. Heat is the climate impact that is arriving most often, on a planet that has now made 40°C afternoons a routine feature of the growing season on four continents.

“Every other threat to the harvest gives you time to act. Heat only gives you a chance if you have already acted. That is the whole of the difference, and it is the difference between a hungry year prevented and a hungry year explained only afterward.”

Figure 6. One shock, every stage at once. Unlike a drought or an El Niño, extreme heat strikes crops, soil, water, and livestock simultaneously and within days and then travels downstream to the harvest that season, to prices in the months after, and, on a lag of roughly a year, to hunger.

What It Means at the Checkout Line

No American eater should mistake a cool morning for immunity from the consequences of a heat wave. The price of food in an American grocery store is set in a global market, and when wheat bakes in Australia, when heat sterilizes rice across Asia, when Europe’s corn and dairy come in short, U.S. commodity prices rise regardless of the weather in Kansas. This is not because American grain is scarce, but because American grain sells into world prices. The damage from a heat dome does not travel at the speed of a headline; it moves at the speed of a growing season, and it moves, reliably and predictably, to the consumer’s receipt everywhere in the world.

The people that the price increases from heat damage moves toward, are the ones least able to pay. Roughly one in four American adults now lives in a food-insecure household, with the lowest-income fifth of households spending a third of their income on food.²⁶ Congress has made cuts to the very safety net that stands between price volatility and hunger for tens of millions of Americans. Every percentage point of heat-driven food inflation that lands in 2027 will land on families who did little to warm the planet and can least afford the rising prices.

Gurjinder Singh, the Punjab wheat farmer, watching his crop shrivel in a March that arrived with temperatures not normally seen until May; Jacob Hoewisch, the Wisconsin dairyman, running fans on electricity he cannot afford over cows that have all but stopped giving milk; the shopper in Ohio staring at the price of ground beef at $6.82 a pound, none of them chose this. But all of them are downstream of the same warming air that is traveling around the world. All of them will pay for the excess heat in the currency the poor always pay in: skipped meals, skipped medicine, sold assets, mounting debt; the quiet emergency that hunger always causes.

This is not a forecast. As of the summer of this writing, excess heat has already carved into the 2026 harvest across the Northern Hemisphere, Western and Central Europe’s maize, the United States’ spring wheat and barley, China’s corn and rice, while a developing El Niño pushes heat and drought into the crops of South and Southeast Asia and Australia (Figure 7).²⁷ The losses are still regional rather than systemic, cushioned by a record 2025 harvest and full reserves; but they are exactly the kind that travel, one growing season later, to the prices on the supermarket shelf.

Figure 7. Where excess heat is hitting crops in 2026. Countries shaded where heat-driven crop stress was reported through early August: confirmed losses (red) across Western and Central Europe, the United States, and China; emerging El Niño heat-and-dry stress (orange) across South and Southeast Asia and Australia. Country-level and indicative, not sub-national.

How Can the Impacts of Extreme Heat Be Mediated?

Heat’s speed is its cruelest trait, but it is also, perversely, its weakness: because heat maps onto the calendar of the crops it threatens, we know in advance which weeks of which growing seasons carry the most risk. What is required is not incremental adjustment. It is deliberate action on four fronts, taken before the season that fails, not after. This means taking action to protect the poor and working classes around the world at a time when all of the major food donors are cutting back both internationally and at home. This will make hundreds of millions of people suffer if it is not reversed.

First, fund heat adaptation and anticipatory relief before the harvest, not after it. Cash, drought- and heat-tolerant seed, and pre-positioned food released on forecast triggers rather than on famine declarations cost a fraction of late-stage emergency response and save lives that late response cannot. Those trigger systems already exist. However, they are being defunded at exactly the moment the heat is intensifying, and that reversal is a choice this budget cycle can still unmake.

Second, protect and expand SNAP and other domestic nutrition programs. The food-price wave from a hot growing season reaches American shelves the following year, stacked on inflation, missing fertilizer and impact of tariffs already in the pipeline. Cutting the primary safety net standing between people dealing with price volatility and hunger, in the same eighteen months that volatility is set to spike, is not fiscal discipline; it is a decision to hand the bill for a warming atmosphere to the households least able to pay it. It is a war on the poor and working classes.

Third, pass a 2026 Farm Bill built for heat volatility. American farmers will plant the crop the world will need facing record input costs and a climate that now delivers a season’s worth of damage in a single week. Crop insurance designed for gradual bad luck, and disaster programs that pay two years late, are not up to responding to a hazard that strikes in an afternoon. Build the farmers safety net for extreme heat explicitly, and build it to reward the diversified, heat-resilient farms most able to survive it - not only the monocrops which are most vulnerable to heat’s disasters.

Fourth, protect the people and the water that grow the food. The same heat that sterilizes the pollen makes the field lethal to the workers standing in it. Enforceable farmworker heat standards are food-security policy, not merely labor policy. The water that irrigation leans on hardest in a heat wave is the water heat is draining fastest, which makes serious investment in water storage, efficiency, and shared drought planning a frontline defense of America’s breadbasket and our harvests, not an afterthought. Rivers, lakes, dams and aquifers that are being used for agriculture have to be protected and their use sustainably divided so that they do not go dry and create humanitarian disasters.

The Emergency That Arrives in an Afternoon

The great climate disasters of the past announced themselves slowly enough that the world could at least pretend to be surprised. Heat has taken away that excuse. We know the thresholds now, crop by crop and degree by degree; we know which weeks of the calendar carry the greatest danger; we can watch the temperature climb toward the number that ends a season in real time, in open data, free to anyone who cares to look.

That knowledge is either a warning or an indictment, and which one it becomes will be decided by whether anyone acts on it. The heating air has delivered its message with a precision no disaster in history has matched. Whether the next hot summer becomes a harvest quietly protected or hunger and famines loudly regretted; belongs, as it always does, to those in power and to the pressure the rest of us are willing to put on them before the thermometer rises again, not after.

So put pressure on your elected officials now, while the window is still open.

Call your elected officials, state and federal, today, tomorrow and the days after that; and demand that the food safety net be restored, the Farm Bill be passed with measures to protect against the impacts of climate change for farmers and for the poor and working classes in America, and the domestic and international food aid budgets be built for the fastest-moving threat that the food system faces before the next heat wave writes another season’s hunger in a single afternoon, in your state, in this country, and across the world.

World Meteorological Organization / Copernicus Climate Change Service, confirmed via the Center for Climate and Energy Solutions (2026): 2024 was the hottest year in the instrumental record, with global average temperatures more than 1.5°C above the 1850–1900 baseline, and 2015–2024 the hottest decade on record.

2. World Meteorological Organization, State of the Global Climate update (Nov. 2025): 2025 set to rank as the second- or third-warmest year on record, with ocean heat content exceeding record 2024 values. World Weather Attribution / reporting in CBS News and PBS NewsHour (Dec. 2025): the 2023–2025 three-year mean crossed 1.5°C for the first time; heat waves were assessed as 2025’s deadliest extreme-weather category, with several studied events roughly ten times more likely than a decade earlier owing to human-caused warming.

3. 2025 European heatwaves, summary record (peak 46.6°C at Mora, Portugal, June 29, 2025); attribution analyses cited therein estimate on the order of 16,500 heat-related deaths across the summer linked to climate change; Spain recorded its hottest summer on record.

4. Seed longevity follows “Harrington’s Rule” (J. F. Harrington, 1963/1972): within roughly 0–50°C and about 5–14% seed moisture, a seed’s storage life is approximately halved for every 1% increase in moisture content or every ~10°F (5.6°C) increase in storage temperature. The related “James’ Rule” holds that the storage temperature in °F plus the ambient relative humidity in per cent should remain below 100. Heat and moisture shorten viability by accelerating respiration, lipid oxidation, and membrane and DNA damage, and by enabling storage fungi. FAO seed-storage guidance and university seed-conditioning references.

5. High soil temperature and moisture stress at sowing reduce germination and seedling establishment; high temperatures during seed maturation on the plant, and excessive-heat mechanical drying after harvest, further reduce viability and vigor. Controlled-storage studies show rice germination falling from roughly 88–95% toward zero over several months at high storage temperature, versus little change under cool storage. Many of the world’s smallholder farmers rely on farmer-saved seed held without temperature or humidity control, heightening their exposure.

Critical high-temperature thresholds for seed set during flowering (rice 37.2°C ±0.2, wheat 27.3°C ±0.5, maize 37.9°C ±0.4), from the review From the floret to the canopy: High temperature tolerance during flowering (Plant Communications / ScienceDirect, 2023), which synthesizes the reproductive-stage heat sensitivity of the three leading cereals. Rice production declines have been documented above roughly 33°C.

8. Regional impacts of extreme heat on agriculture: northern India’s 2022 heat wave was associated with milk-output declines of up to about 15% and state-level wheat-yield losses of roughly 9–34%, after which India restricted wheat exports in May 2022; estimates vary by state.

9. European Commission and insurance-sector estimates (2024–2025): extreme weather costs EU agriculture roughly €28 billion a year, about 6% of crop and livestock output, with only an estimated 20–30% of losses insured. Early tallies from the summer 2025 European heat pointed to substantial damage to French corn, to roughly half of some regions’ carrot production, and to mass poultry mortality.

10. Gurjinder Singh, a wheat farmer in Punjab, India, quoted in FairPlanet, “Saving India’s Wheat Yield from Rising Heatwaves” (August 2022): Singh reported his 2022 wheat output falling from about 23–25 quintals per acre to 14–15, roughly a 40% loss, after the heat wave that began in March. India’s March–April 2022 heat, its hottest March in 122 years, is estimated to have cut wheat yields 10–35% across the northern wheat bowl of Punjab, Haryana, and Uttar Pradesh.

11. The term flash drought was introduced by Svoboda and colleagues at the U.S. National Drought Mitigation Center in 2002 and later formalized by the American Meteorological Society as an unusually rapid-onset drought marked by a multi-week period of accelerated intensification culminating in sectoral impacts. Operational monitoring relies on evaporative-demand indices; one common threshold is a 50% or greater increase in atmospheric evaporative demand over two weeks, sustained thereafter. NOAA / National Integrated Drought Information System (drought.gov).

12. Xing Yuan et al., “A global transition to flash droughts under climate change,” Science 380 (2023): drought intensification has accelerated over subseasonal timescales, with a transition toward more flash droughts across roughly 74% of the IPCC SREX global regions over the past 64 years, attributed to anthropogenic climate change via amplified evapotranspiration and precipitation-deficit anomalies; the shift is fastest over Europe, northern and eastern Asia, the Sahel, and western South America, and is projected to expand across most land areas under higher-emissions scenarios.

13. Jordan I. Christian et al., “Global projections of flash drought show increased risk in a warming climate,” Communications Earth & Environment 4 (2023): annual flash-drought risk over cropland is projected to rise from about 32% (2015) toward 49% in North America and 53% in Europe by 2100 under the highest-emissions scenario. Loss figures: the 2012 U.S. flash drought exceeded $30 billion in economic losses (per reporting on Yuan et al. 2023); the 2017 northern Plains (Dakotas–Montana) flash drought caused an estimated $2.6 billion in U.S. agricultural losses (Dilling et al. 2017; Neelam et al., Geophysical Research Letters, 2024).

14. Event accounts from NOAA / NIDIS drought status updates and retrospectives (drought.gov): the June 2023 Midwest flash drought (dryness covering roughly 64% of U.S. corn production at the onset of pollination; record-low Mississippi River stages on 13–18 October 2023, with barge-load restrictions and saltwater intrusion in southern Louisiana); the 2023 Southeast fall flash drought (record Livestock Forage Disaster Program payouts, concentrated in Mississippi, Tennessee, and Alabama); and the June–July 2024 mid-Atlantic flash drought affecting corn from the Carolinas to Pennsylvania.

15. Greg Lee, a dryland farmer and rancher in Divide County, North Dakota, quoted in Meera Subramanian, “The Flash Drought Brought Misery, but Did It Change Minds on Climate Change?” Inside Climate News, July 17, 2018. The 2017 flash drought across the U.S. Northern Plains caused an estimated $2.6 billion in agricultural losses.

16. University of Minnesota Extension, Heat stress in dairy cattle: mild heat stress reduces milk output by roughly 2.5 lb per head per day, with larger losses as stress intensifies; high-producing cows can begin to experience heat stress at air temperatures as low as the mid-60s °F. Australian grazing-dairy study (Univ. of Melbourne robotic dairy, 2020) recorded a ~14% drop in daily milk production from low to high temperature-humidity index.

17. Washington State University Veterinary Medicine Extension (2025) and Frontiers in Veterinary Science (2023): U.S. livestock heat-stress losses estimated at up to ~$2.3 billion/year (2003), equivalent to roughly $2.9 billion in 2024 dollars, with dairy cattle accounting for roughly 63% of U.S. livestock heat-stress losses.

18. Journal of Dairy Science (2003) and heat-stress mortality literature: several hours of temperature-humidity index above ~84 with little or no nighttime recovery (THI falling below ~74) can cause death in vulnerable feedlot and dairy cattle; on-farm mortality rises measurably during multi-day heat waves (≥3 days at or above ~32°C).

19. Jacob Hoewisch, owner and operations manager of the fifth-generation Hoewisch Dairy Farm in Fremont, Wisconsin, in reporting by WLUK-Fox 11 (July 2026). Above roughly 70°F, cows can give 3–10 pounds less milk per day, a 5–15% drop, which for a 240-cow farm can mean losses of up to about $13,000 in a month; prolonged overheating can also cause a cow to lose a pregnancy.

20. Poultry and small ruminants: birds have no sweat glands and cool only by panting, which leaves them acutely vulnerable to heat (University of Minnesota and University of Tennessee Extension); turkeys are among the most heat-sensitive poultry because of their size. Reporting on the June and July 2026 European heat wave described French poultry deaths in the millions, with turkeys hardest hit, and France’s 2003 heat wave killed an estimated 4 to 5 million chickens and turkeys, about 2% of the national flock. St-Pierre et al. (2003) put U.S. poultry heat-stress losses at roughly $128 to $165 million a year. Chicken is now the world’s most-consumed meat by volume. On small ruminants, heat and drought reduce pasture and cut lambing and kidding in the pastoral systems on which many of the world’s poorest households depend.

21. On stored-grain deterioration: warm, moist grain respires and self-heats, forming hot spots that promote mold growth, insect infestation, dry-matter loss, reduced nutritional value, and loss of seed germination; as a rule of thumb, allowable storage time falls by roughly half for each ~10°F (5.5°C) rise in grain temperature, and storage insects are most active between about 70 and 90°F. Mycotoxins produced by storage fungi are chemically stable and are not reliably removed by milling or cooking. North Dakota State University Extension; Bayer Crop Science; reviews of stored-grain fungi and mycotoxins.

22. Aflatoxin (produced by Aspergillus flavus) is the most acutely toxic and most tightly regulated mycotoxin and a recognized liver carcinogen, favored by heat- and drought-stressed crops in the field and by warm, humid storage. Paola Battilani et al., “Aflatoxin B1 contamination in maize in Europe increases due to climate change,” Scientific Reports 6:24328 (2016): under a +2°C scenario (the most probable near-term case), the mean aflatoxin index for European maize rose about 92% and the high-risk zone shifted northward. Van der Fels-Klerx et al. (2016) and subsequent work document A. flavus becoming established in southern and central Europe; Yu et al. (2022) describe a comparable northward shift in the United States. A 2026 analysis of 17,263 peanut samples in China (2009–2022) found aflatoxin B1 contamination significantly higher than a decade earlier, with temperature explaining roughly 49% of the increase (npj Science of Food).

23. Hay baled above roughly 20% moisture supports rapid microbial growth that consumes sugars and proteins, degrades feed value (partly through the Maillard/browning reaction, which binds protein into indigestible forms), and generates internal heat; above about 170°F spontaneous combustion becomes a risk, with most fires occurring within roughly six weeks of baling. Mississippi State, South Dakota State, and Missouri Extension services.

24. High-temperature storage accelerates rice deterioration: rising fatty-acid value (rancidity) and lipid peroxidation, loss of palatability and head-rice yield, discoloration, and loss of germination and nutritional quality, with damage increasing at higher storage temperature and moisture content; above ~16% moisture, warm storage promotes Aspergillus and Fusarium growth and aflatoxin accumulation. Storage-temperature studies in the Journal of Stored Products Research, Journal of Food Processing and Preservation, and Cereal Chemistry.

25. Post-harvest and cold-chain losses: the FAO estimates that roughly one-third of food produced is lost or wasted, with about 14% lost between harvest and retail and on the order of 12% (≈526 million tonnes) attributable to insufficient refrigeration; inadequate cold chains contribute to foodborne illness, which the World Health Organization links to roughly 420,000–600,000 deaths a year. Rising temperatures and extreme heat increase cold-chain energy demand and failure risk and accelerate spoilage. Yin et al., “Heat stress increases food loss during harvest: empirical evidence from China,” Journal of Stored Products Research (2026), identifies heat strain at harvest as a direct, previously overlooked climate channel into food loss; FAO Food Loss and Waste data indicate an average cereal loss of about 5.2% at harvest.

26. Estimates of U.S. food insecurity differ substantially by survey instrument, and the divergence is itself part of the story. The Urban Institute’s Well-Being and Basic Needs Survey, a nationally representative internet panel, found 24.2% of adults 18 and older reporting household food insecurity in the previous twelve months as of December 2025, and 27.7% of adults 18 to 64 (Karpman, Waxman, Gupta, Gonzalez and Kennedy, “Food Insecurity Remained High in 2025, As Safety Net Cuts Loom,” Urban Institute, March 2026). The USDA’s Current Population Survey Food Security Supplement, the long-standing federal measure, put household food insecurity at 13.7% in 2024, some 47.9 million people (Rabbitt et al., ERR-358, December 2025); Feeding America’s Map the Meal Gap 2026, which models local rates from that same federal data, reports 14.4% of individuals. The Urban Institute attributes its higher figures to the absence of the CPS income screener, a six-item rather than eighteen-item scale, and survey mode, since respondents report food hardship more readily in self-administered internet surveys than to an interviewer. State-level survey work runs higher still: the Greater Boston Food Bank and Mass General Brigham found 40% of Massachusetts households food-insecure in 2025, up from 19% in 2019. USDA discontinued the federal series in September 2025, making 2024 the last official national baseline. Food spending share: USDA Economic Research Service, Food Prices and Spending, drawing on Bureau of Labor Statistics Consumer Expenditure Survey data. In 2024, households in the lowest income quintile spent an average of $5,498 on food, 33.0% of before-tax income, against 12.2% for the middle quintile and roughly 8% for the highest. The share is volatile for poorer households, ranging between 28.8% and 42.6% over the past two and a half decades, because their incomes are less stable and grocery prices move.

Gaza’s Children Can’t Afford to Wait: All children of the Gaza Strip under 5, more than 320,000 children, are at risk of becoming acutely malnourished.

It’s worth understanding because it explains both why acute malnutrition kills so fast and why it’s so treatable when food aid and medical treatment arrive in time.

Comforting Global Hunger Number Arrived from the U.N. at the Worst Possible Moment

On July 21, five UN agencies released the 2026 edition of The State of Food Security and Nutrition in the World, and the sentence that traveled among the major media was a soothing one: global hunger had declined for a third straight year, to about 645 million undernourished people in 2025, some 14 million fewer than the year before.¹ The head of the FAO gave the wires their quote: “We can bend the hunger curve” and within hours the headline was set, in near-identical stories, across dozens of outlets: global hunger is easing.²

Here is what the good news headline sat next to, in the same month, from the same agencies:

1) two famines were confirmed in a single year for the first time in modern times, in Gaza and Sudan;

2) four countries are at risk of famine right now: South Sudan, Mali, Haiti, Yemen;

3) A record 266 million people are in acute, life-threatening hunger;

4) And the sharpest humanitarian funding collapse in a generation helped create this new acute hunger and push global hunger numbers to their records.³

The comforting number did not just miss that suffering; it is being used to deny it.

“An accurate number, stripped of its date and its caveats, is not information. It is politically useful cover for the people and governments defending recent aid reductions.”

This is not a complaint about a statistic. The statistic is sound. It is a warning about what is being done with it because a headline that says hunger is falling is the most useful thing in the world to anyone who wants the aid cuts made when USAID was dismantled and other European donor countries joined in cutting foreign aid to look painless. These reductions in foreign aid are not painless. This piece is about the people the number leaves out, and about why leaving them out is a choice with consequences. Hunger is a policy choice, and donor governments have enacted policies that leave tens of millions with less humanitarian assistance and extreme hunger and other humanitarian disasters.

The People the Headline Cannot See

The falling number is a measure of chronic hunger, that is the slow, structural kind of hunger, estimated from food-supply balance sheets and surveys that arrive a year or more late. It is the wrong instrument for the emergency now underway. That does not make the measure wrong—it makes it unsuitable as a description of today’s emergency; it is pointed at the wrong year, 2025. The emergency is acute hunger, the kind that kills within a season, and it is not falling - it is at a record high and climbing.³

Behind that record are people with names and coordinates. In El Fasher and Kadugli, the two Sudanese towns where the Famine Review Committee confirmed famine, people starved under siege while the world’s attention followed this cheerier statistic and ignored the hunger crisis.⁴ Across Sudan, nearly 4.2 million cases of acute malnutrition are expected in 2026, including more than 800,000 severe cases of acute malnutrition among children where it is the deadliest.⁵ In South Sudan, one of four countries at risk of famine, aid is being rationed so tightly that agencies can only reach those already in catastrophe, leaving millions in crisis to slide toward famine untouched.⁶ None of these people are in the 645-million headline, because the instrument that counts them is a different one, and the press quoted the headline that looks away from today’s global hunger crisis.

The Cuts Are the Cause, and We Can Prove It

The good-news framing treats hunger as a problem quietly solving itself. The truth is that the fastest-moving force in global hunger right now is a policy decision: the abrupt dismantling of humanitarian and food aid and its fingerprints are on the record in a way that is hard to ignore or wave away.

Start with the funding. After the January 2025 executive order suspending U.S. foreign aid and the dismantling of USAID that followed, the World Food Programme expects to run on roughly 40 percent less funding or about $6.4 billion, down from $10 billion in 2024 to deal with increasing humanitarian crises.⁷ The June 2026 hunger warning came against a 59 percent drop in food-aid funding.⁸ That is not a rounding error. It represents the removal of one of the principal safeguards standing between for tens of millions of people and severe hunger and famine.

Now the effect. In Nigeria, funding shortfalls forced WFP to scale down so far that it could reach only 72,000 people in February 2026, down from 1.3 million during the 2025 lean season, while malnutrition in several northern states deteriorated from “serious” to “critical.”⁹ Across Uganda, Kenya, and Bangladesh, rations were halved or suspended for millions of refugees which occurred alongside documented deaths in Kenyan refugee camps, according to Refugees International.¹⁰

Perhaps the strongest field evidence comes from Mali. In Mali, WFP ran what amounts to a natural experiment: where in some parts of the country families kept receiving full rations, (the number of calories and nutrients recommended by public health research) acute hunger fell 34 percent. In other parts of the country where not all of the aid was received and as a result, rations were cut, acute hunger surged 64 percent. While not a randomized trial, the comparison offers unusually strong real-world evidence under humanitarian conditions. These rates of hunger were in same country, same season, opposite outcomes, split primarily by whether adequate levels of survival rations of food arrived.¹¹ This is as close to a causal relationship available of causation as field data ever gets, and it points in one direction: the foreign aid cuts made by the United States and European countries have substantially increased hunger in many affected regions around the world.

“Same country. Same season. Where the food arrived, hunger fell by a third. Where it was cut, hunger surged by two-thirds. That is not a correlation. That is evidence strongly consistent with causation.”

The human toll of the cuts has been estimated through modeling, and the numbers are staggering even at the low end. The Center for Global Development puts humanitarian and food-aid cuts at the potential for roughly 490,000 lives lost per year, part of a wider toll it places near 1.6 million annually; a Lancet study projects more than 14 million additional deaths by 2030, 4.5 million of them children, if the U.S. and European aid defunding is not reversed.¹²These are models, with real uncertainty. But they are consistent with the same reality the Mali experiment measures directly, and they do not describe a world where hunger is quietly easing.

Figure 1. The two hunger lines the coverage collapsed into one. In blue, the headline: chronic undernourishment, easing to about 645 million in 2025 (left axis) a lagging average. In red, the climate-driven slice of acute hunger, up nearly fivefold since 2020 to 87.5 million (right axis) the current emergency. Much of the media coverage emphasized the blue line while giving comparatively less attention to the red one. Sources: SOFI 2026 (FAO/IFAD/UNICEF/WFP/WHO); GRFC 2020–2026 (GNAFC). Chronic values for 2022-24 approximate.

The Data Is Vanishing Along with the Aid

There is a second cruelty folded into the first. The same budget cuts that are deepening hunger are also defunding the systems that count how many people are hungry, which means the reassuring number is not only late, but also built on the thinnest evidence in a decade according to the 2026 Global Report on Food Crises and will miss more hungry people as time passes.

The Global Report on Food Crises said so plainly: funding cuts and blocked access produced the lowest availability of food-security data in ten years.¹³ In 2025, 18 countries and territories lacked comparable data, including Burkina Faso, the Republic of Congo, and Ethiopia, which together had more than 27 million acutely food-insecure people in 2024 who are simply missing from the totals.¹⁴ A number can fall because fewer people are hungry; it can also fall because fewer people are counted. When the counting is being dismantled in the same act that the aid to feed hungry people is being dismantled a headline that reported the decline has mistaken a blind spot for good news may be cited by the people and governments defending aid reductions as evidence that current policies have not significantly worsened hunger and potentially to keep cutting aid even as tens of millions of people are in desperate hunger.

How an Accurate Number Tells a Lie

It is worth naming exactly how the distortion works, because it will happen again with next year’s report unless it is called out now. Nobody fabricated anything. The issue is not fabrication. It is framing. The lie is assembled from true sentences, in four moves.

● The date is dropped. “Hunger fell in 2025” becomes “hunger is falling,” and a year-old average is passed off as a live trend.

● The instruments are swapped. The chronic-hunger number stands in for the acute-crisis number, so the falling line covers the rising one where millions are in the worst stages of hunger.

● The caveats are cut. The report’s own warnings including the data gaps, the regional reversals, data limitations, the lack of fertilizer, the excluded El Niño and other qualifying context rarely survive the trip to the headline.¹⁵

● A hope is printed as a fact. “We can bend the curve” is a plea for action; it gets reported as a description of progress.

The result is a story true in every particular and false in its total effect. This is the hardest kind of misinformation to correct, because every sentence passes a fact-check while the whole misinforms. In this year, the false impression is doing political work: it is being used by the people and countries defending recent aid reductions to suggest the humanitarian consequences have been limited, at the exact moment the famines say otherwise. By definition, famine represents the most extreme stage of food insecurity, a famine is “an extreme and widespread shortage of food that causes severe malnutrition, starvation, and death.” [1, 2]

What Is Actually True

None of this means burying the SOFI number. It means telling the whole truth which it is only a part of all of which is available from the very same reports:

Chronic hunger, on a lagging estimate, edged down for a third year, a real, slow, statistic carried by a few countries with revised data. Although the simultaneous decline in comparable data warrants caution when interpreting long-term trends, at the same time, acute hunger is at a record: 266 million people, two confirmed famines, four more countries at risk of famine. The improving line od chronic hunger describes the past; the worsening one describes the present acute hunger and with El Niño coming the near future. Both rest on the sparsest data in a decade. One major factor driving the worsening acute crisis is a choice Western Donor Countries made to cut the aid, which the Mali evidence suggests can be substantially mitigated where adequate food assistance is restored tomorrow, because where the food still arrives, hunger still falls.

That is not despair. It is the report, read to the end, with the people left out the frame. Much of the major media coverage emphasized the opening finding while giving comparatively little attention to the report’s discussion of acute hunger, data gaps, and humanitarian funding. They ran the just ran the first sentence and stopped.

What You Can Do About It

This is the rare humanitarian catastrophe that is being measured in advance, in public, in detail. Many of the deaths that may follow are foreseeable and mostly preventable through different policy choices. The window to change the decision is open now, and it does not require heroics. It requires refusing the comfortable version of the story and acting on the true one where aid cuts are making people hungry all over the world. The reduction in crops from the fertilizer that never arrives is being modeled and mapped in advance. The OECD–FAO Outlook projects reduced fertilizer use cutting cereal harvests in low-income countries, and satellite systems like the FAO’s GIEWS and the EU’s ASAP track where those losses are concentrated. The hunger this will cause is being forecast even now; the only thing missing is the will to act on the forecast. An El Niño is forecast six to twelve months ahead, the single most predictable pattern in the climate system, tracked instrumentally for about 150 years. And where its droughts will harden into hunger is charted in advance, region by region, by the early-warning systems built for exactly that purpose. Famine is on the calendar before it happens. Now it is a question of whether the world humanitarian organizations will have the funding to prepare for what we know is coming.

Restore the funding, this budget cycle. The single most direct lever is restoring the humanitarian and food-aid that collapsed in 2025. The Mali comparison illustrates the central argument: where the rations arrive, hunger falls. Tell your representatives, both state and federal, that reversing the cuts is not charity, it could substantially influence whether famine conditions worsen or are contained, and whether anticipatory funding is in place for southern Africa’s planting season and the four famine-risk countries which cannot wait for a distant or even the next fiscal year.

Challenge misleading headlines. When you see a major media outlet report that “global hunger is falling,” challenge them which hunger and which year. Share the acute hunger numbers alongside the chronic ones. Tell people that aid reductions are worsening humanitarian food crises and increasing famine risk in multiple countries meaning people will starve to death from lack of food. A public that knows the difference between a lagging average and a live famine is much easier to encourage into action.

Fund the counting, not just the feeding. The vanishing data is its own emergency. The monitoring systems called the IPC, FEWS NET, the crisis reports are what make famine foreseeable and therefore preventable. Modern famine early-warning systems expanded after the devastating famines of the 1980s, reflecting a growing recognition that timely data saves lives. Defending them is cheap and critical for understanding what is happening with global hunger.

“The famines were forecast. The cuts were chosen. The headline was optional. Every one of those is still ours to change but only if we stop mistaking a year-old average for the end of the emergency that has just started and is only going to get worse as more aid is withheld.”

Check It Yourself

Every figure here is public and free, released by the same agencies whose headline this piece disputes. Hold both the report and its coverage to account:

● The chronic number, in full: the SOFI 2026 report and the agencies’ launch release. Please read past the headline into the caveats.

● The acute crisis: the Global Report on Food Crises 2026 for the 266-million figure, the climate driver, and the data-gap warning.

● The famines, live: the IPC country analyses for the formal classifications and the FAO–WFP Hunger Hotspotsoutlook.

● The cuts and their toll: Refugees International’s tracking of the aid-cut impact and the Lancet defunding study.

● Hunger in near-real time: WFP’s HungerMap Live and FEWS NET, this system could correct any number a year out of date if they were operational.

The Sentence That Should Have Traveled

There was a true headline available, and it fit: “Chronic hunger inched down on a year-old estimate, even as acute hunger hits a record high, two famines were confirmed, and the aid cut driven humanitarian crises are still deepening.” It is less comforting than “hunger is falling,” but it has the advantage of being true and not leaving out the people dying of starvation or the tens of millions of people who have been made hungry due to the aid cuts.

The child in El Fasher, the family in northern Nigeria whose ration was cut from a program that once reached 1.3 million and now reaches 72,000, the refugee in Kenya who died after the food basket was halved, neither of them are in the 645-million headline, and all of them are in the world it claims to describe. They are not a rounding error in an improving trend. They are the trend; in the places where the trend is measured honestly and the humanitarian alarm bells are ringing. A press that reports the average and skips the emergency has not lied. It has done something quieter and, this year, much more deadly: it has handed the people and countries who cut the aid a headline that says nobody got hurt and let the rest of us believe it.

An estimated 645 million people (7.8 percent of the global population) faced hunger in 2025, down from 8.1 percent in 2024 and 8.6 percent in 2022 — about 14 million fewer than 2024 and 43 million fewer than the 2022 peak. The metric (prevalence of undernourishment) is a modeled estimate built from food-supply, population, and household-survey inputs that arrive with substantial lag.

2. FAO Director-General QU Dongyu, remarks at the SOFI 2026 launch, 21 July 2026: “We can bend the hunger curve.” The launch release ran, in near-identical wording, across FAO, WFP, WHO, UNICEF and downstream outlets as “Global hunger levels ease for third consecutive year.”

3. FSIN and Global Network Against Food Crises. 2026. Global Report on Food Crises 2026 (GRFC): 266 million people (22.9 percent of the analysed population) faced high levels of acute food insecurity (IPC/CH Phase 3 or above) across 47 countries in 2025; acute food insecurity has nearly doubled over the past decade; and two famines (parts of the Gaza Strip and the Sudan) were confirmed in the same year for the first time in the report’s history.

4. IPC Famine Review Committee (2025): Famine (IPC Phase 5) confirmed in El Fasher (North Darfur) and Kadugli (South Kordofan), Sudan, as of September 2025, with a risk of Famine in some 20 additional areas.

5. IPC / UN OCHA (2026): nearly 4.2 million cases of acute malnutrition projected in Sudan in 2026, including more than 800,000 severe cases; SMART surveys found GAM levels exceeding the Famine threshold in parts of North Darfur in December 2025.

6. IPC South Sudan Projection Update, April–July 2026: 7.8 million people (55 percent of the population) in IPC Phase 3 or above, with a risk of Famine in Luakpiny/Nasir and Ulang (Upper Nile) and Nyirol and Akobo (Jonglei); limited resources have forced programming to concentrate on populations already in Catastrophe.

8. FAO–WFP Hunger Hotspots (June 2026) and associated reporting cited a 59 percent drop in food-aid funding against the June–November 2026 outlook.

9. UN News / WFP (January 2026): in Nigeria, WFP could reach only 72,000 people in February, down from 1.3 million assisted during the 2025 lean season, as malnutrition in several northern states deteriorated from “serious” to “critical.”

10. Refugees International, A Generational Collapse: Tracking the Toll of the Humanitarian Aid Cuts (February 2026): ration suspensions and cuts across Uganda, Kenya, and Bangladesh; in Kenya, the minimum food basket was cut ~40 percent for nearly 800,000 refugees, with documented deaths.

11. WFP, “Humanitarian aid cuts push millions deeper into hunger … West and Central Africa” (January 2026): in Mali, areas where families received reduced rations saw a ~64 percent surge in acute hunger (IPC 3+) since 2023, while communities that received full rations saw a 34 percent decrease.

12.

These are modeled projections with substantial uncertainty.

13. GRFC 2026: funding cuts and limited access to conflict areas produced the lowest availability of food-security data in a decade.

14. GRFC 2026: in 2025, 18 countries and territories lacked comparable data, including Burkina Faso, the Republic of Congo, and Ethiopia, together accounting for more than 27 million acutely food-insecure people not captured in comparable totals.

15. SOFI 2026: the report’s five-year projections do not account for the effects of weather extremes such as the 2026–27 El Niño, which it notes could further compound the numbers; on current trends roughly 510–512 million people are projected to remain chronically undernourished by 2030, most in Africa, missing Sustainable Development Goal 2. Hunger also continued to rise across most of Africa and western Asia even as the global average fell.

A note on sourcing. Every figure above is drawn from the 2026 SOFI report, the 2026 Global Report on Food Crises, the IPC country analyses, the June 2026 Hunger Hotspots outlook, WFP operational reporting, Refugees International, or the peer-reviewed mortality literature — all public.

The Year the Averages Lied

Halfway through 2026, the food system tells two stories, and only one is reassuring. The reassuring one is in the aggregates: the FAO Food Price Index sat at 130.3 in June, barely above a year earlier and nearly a fifth below its 2022 peak, with the world’s cereal harvest tracking toward its second-largest ever on full reserves.¹ The other is written crop by crop: vegetable oils prices were 23 percent higher than a year ago and meat set an all-time record; a flood erased a fifth of a Bangladeshi rice season; drought sat over half the world’s cocoa belt; Spain gathered its smallest orange crop in sixteen years; two thirds of U.S. winter wheat was not healthy enough to harvest.² The averages held. The specifics did not.

Figure 1. The calm on the surface. The aggregate readings behind the reassuring story of mid-2026 — a food-price index below its 2022 peak, a near-record cereal harvest, rebuilt stocks. All axes begin at zero, so the bars sit almost level; the damage is not visible at this altitude. Source: FAO, 2026.

An annual average is a place to hide. It is the crop, the region, and the week that tell you where the climate actually landed and in 2026 it landed unevenly, and hard.

What follows takes stock of what the first six months have already done to real crops in real fields, and a glance at the landscape on which the coming El Niño will land.

The Crops That Failed First

The clearest losses fell on the specialty and tree crops that smallholders grow and no national average can rescue. A pre-monsoon flood took the Bangladeshi boro rice at harvest peak; drought hit the West African cocoa belt during pod formation even as the price fell on a demand glut, the falling price is not the result of a healthy crop; and the vegetable-oil index, showing prices up 23 percent to its highest since 2022, is where the year’s bad weather actually shows up on the shelf due to limited supply.³

The People at the Growing End

Every figure has a household behind it, and for specialty crops it is usually a smallholder with no cushion. In Bangladesh the April floods hit more than 236,000 farming families and destroyed some 214,000 tonnes of rice with no chance to replant; in West Africa, when futures collapsed, Ivory Coast cut its farmgate price by more than half, to about $2.13 a kilogram, so growers caught the downside of a boom they never shared; and Vietnam’s coffee farmers will face a confirmed El Niño before they have recovered from the last drought.⁴

A staple crop failing is a statistic in a report. A specialty crop failing is a family with one income, one harvest, and no cushion.

Meat: A Record and Its Mirror

One line in the world ledger never stopped climbing: the FAO Meat Price Index reached a record 131.0 in June, about a third above its 2014–2016 base. But an index is not a butcher’s ticket, and June’s record was written mostly in poultry — higher Brazilian export prices and firm lamb quotations — while global beef and pork prices actually eased.

The American cattle story is the mirror, and it runs the other way. The U.S. herd has shrunk to 86.2 million head, the smallest since 1951, after eight years of contraction and drought-driven liquidation that no single season can reverse. It shows up not in the global index but on the domestic shelf, where retail ground beef has climbed past $6.80 a pound; and because rebuilding a herd takes three to four years, relief is unlikely before 2028.⁵

The heat reached every animal. Sheep and goats lose lambing on burnt pasture, even the drought-proof camels of the Horn of Africa have begun dying, and a late-June European heatwave killed an estimated 2.5 to 3 million French broiler chickens.⁶

Grain: The Averages Lied Again

If one crop proves the thesis, it is European maize. A third heatwave since late May burned France’s crop to about 9.4 million tonnes, a third below last year and its smallest in over three decades, and COCERAL cut EU-and-UK grain by 23.4 million tonnes.⁸ A fourth heatwave is hitting France right now. Kenya’s maize fell on a June dry spell and Brazil–Thailand sugar is seen down a tenth. Gathered in a table the failures are dramatic; gathered in the world total they nearly vanish. That gap is the whole argument of the impacts of climate change on hunger.⁹

The Southern Hemisphere’s Dry Turn

The El Niño’s dry phase has reached the south before the harvest even began. Australia’s dry autumn cut canola area by nearly a third and trimmed the wheat crop toward 26.7 million tonnes for 2026–27, 25% below last year, with ranchers selling cattle in record numbers; across the Pacific, Argentina’s early-2026 drought scare eased and Brazil banked a record soybean crop even as its safrinha corn went into the dry season on thin soil moisture.¹⁰

What the Ledger Says, and What Comes Next

Add the six months together: the shocks were real but regional, sharp but not systemic, concentrated in the crops least able to average out and cushioned by a record 2025 harvest and full reserves.¹¹

So far, 2026 has bruised the food system without breaking it. The open question is what happens when the next blow as a super El Niño lands before the bruises heal.

Every shock so far landed in the first half of a year whose defining event does its worst work in the second. On June 11 the U.S. Climate Prediction Center confirmed an El Niño observed, not forecast, with a better-than-96-percent chance of persisting and a peak near +3.6°C that would be the strongest El Niño ever to impact the world since records have been kept. It will be landing on the growing seasons of the Southern Hemisphere and the tropics. ¹² The sharpest forward risks include Philippine rice, a quarter to a third at risk; a weak Indian monsoon and a held sugar-export ban; and palm oil, where Indonesia and Malaysia hold 88 percent of supply on thin stocks. The pivotal case is southern Africa, but two La Niña years left near-record stocks, so even a real drought should bite more softly than 2016.¹³

The distribution has shifted toward the harder outcomes. The crops at risk are already named, and the reserves are being drawn down before the peak arrives. The forecast is conditional. The window to act on it is not.¹⁴

The Humanitarian Map of the Second Half

The crop ledger reads one commodity at a time; the humanitarian sector reads one region at a time, and the two converge.UMCOR’s June outlook resolves the confirmed El Niño into a redistribution of drought, flood, and heat across ten regions, with a window of greatest concern from July 2026 through March 2027, exactly the stretch the crop calendar leaves exposed, and a three-phase timeline that is paid out in crop failure, displacement, and disease by early 2027. ¹⁵

The El Nino is coming as aid agencies struggle to provide food for the tens of millions of people in need in Iran, Suda, Gaza, Haiti, Myanmar, Syria and elsewhere.

Figure 3. The same second half, drawn as a humanitarian map. UMCOR’s June 2026 outlook resolves the El Niño into a redistribution of drought (reds), flood (blues), and heat across ten regions, with a concern window of Q3 2026 – Q1 2027. Source: UMCOR, drawing on WMO, NOAA CPC, FAO GIEWS, and WFP.

The call for early action arrives in the worst funding environment in a generation. The OECD reported 2025 aid down 23 percent, humanitarian aid down more than a third, and core UN funding down 27 percent after an 87-percent U.S. cut, with the 2026 appeal now reaching barely a third of those in need. The warning is not the problem; money has always moved after the photographs arrive, and the institutions built to change that are the ones being defunded.¹⁶

The scale of that retreat is now measurable, and it is still deepening. The OECD’s preliminary 2025 figures show official development aid falling for a third consecutive year, to its lowest level since 2014, with a further decline of roughly 7 percent projected for 2026 that has barely begun to land. The contraction is strikingly concentrated with the five largest donors accounting for 96 percent of the reduction in aid, led by a 57 percent cut from the United States. The cuts in aid fall hardest where the cushion is thinnest: bilateral aid to the least-developed countries and to sub-Saharan Africa each dropped more than a quarter in 2025 and is forecast to fall by double digits again this year, while global health financing is on course to run as much as 63 percent below its 2022 peak. What remains is being redrawn by geopolitics rather than need, with more aid flowing to Ukraine in 2025 than to all the least-developed countries combined. The humanitarian system downstream is, in its coordinator’s words, “overstretched, underfunded and under attack.” Roughly a fifth (only 20%) of its appeals have been funded this year, and more than 320 aid workers have been killed in a single year. ¹⁷

The humanitarian map of the coming year, shows a redistribution of drought, flood, and heat across five continents and a calendar that says the reckoning arrives after the existing food reserves have already been spent.

The current state of international aid: the OECD’s preliminary 2025 data (April 2026) show DAC official development assistance fell 23.1% to $174.3 billion , the steepest drop on record and a third consecutive annual decline, its lowest level since 2014, with a further ~6.9% projected for 2026; the five largest donors account for 96% of the fall, led by the United States (−57%). Bilateral aid to least-developed countries and sub-Saharan Africa fell 25.8% and 26.3% in 2025 and is projected to drop a further ~10.9% and ~11.6% in 2026, while health financing is projected as much as 63% below its 2022 peak. DAC members’ 2025 aid to Ukraine exceeded their combined aid to all least-developed countries. The UN’s 2026 Global Humanitarian Overview seeks $33 billion for 135 million people after 2025 funding hit a decade low (~$12–15 billion) and reached 25 million fewer people; UN relief chief Tom Fletcher called the system “overstretched, underfunded and under attack,” with only about 20% of appeals funded and more than 320 aid workers killed in 2025.

The July forecast runs are in, and they describe something no working forecaster has ever seen. According to 667 ensemble members from 14 seasonal prediction systems, the multi-model median now puts this winter’s El Niño at a peak of 3.6°C in the Niño 3.4 region of the tropical Pacific. This is roughly 0.8°C beyond the strongest El Niño event in a century and a half of observation. ¹ Ninety-one percent of the ensemble members predicted that this El Niño will exceed the all-time record. The ocean itself is not waiting for the models: daily sea surface temperatures in the region are already running around 2°C above their era-adjusted average in mid-July, warmer at this date than in 1997 or 2015, the two most explosive El Niño onsets ever measured, and by a margin that is not close. ²

The onset race: daily sea surface temperature anomalies in the Niño 3.4 region for 2026, against 1997 and 2015, the two most explosive El Niño onsets previously measured. The dashed line is the multi-model forecast median; the shading spans the middle 80 percent of the 667-member ensemble.

The temptation will be to file this under meteorology. File it instead under food, and under hunger.

An El Niño is not a storm. It does not arrive with wind and fury and then recede. It is a reorganization of where rain falls on Earth, a slow, hemisphere-spanning transfer of moisture away from the croplands of Southeast Asia, southern Africa, Central America, and northeastern Brazil, and toward places that cannot use the rain to produce food such as the open Pacific, the deserts of coastal Peru, the flood plains of the Horn of Africa. The warm water is only the mechanism; the failed harvests are what people will actually live through. Since the global food system runs on a handful of staple crops grown in a handful of climate-exposed regions, a sufficiently large El Niño is not a weather anomaly at all. It is going to be a global food shock on a twelve-month fuse. ³

“An El Niño does not destroy one harvest in one place. It reorganizes the rain over half the planet, on a schedule the world’s croplands were never meant to adapt to.”

4Hunger.org has spent the past several months documenting the two crises already squeezing the food system: the fertilizer supply shock that followed the closure of the Strait of Hormuz in February (see Fertilizer Famine), and the two-year drought that has driven the American cattle herd to its smallest size since 1951 and the U.S. wheat crop to its smallest since 1972 (see Parched Ground). The forecast now on the table is the third shock, and it is aimed squarely at the harvests of the next eighteen months all around the world.

A Map of What Comes Next

Strong El Niños do not damage the world’s agriculture randomly. They damage it in a pattern that has been documented across 150 years of El Niño events, and the pattern is brutally consistent. ⁴ To understand the geography of what is now forecast, start with where previous events did their damage, because they do it in the same places again and again.

Indonesia, the Philippines, and mainland Southeast Asia sit first in the line of fire, and the impacts are already arriving there. Strong El Niños suppress the rains across the Maritime Continent. Rice planting is delayed, reservoir levels fall, and the drained peatlands of Sumatra and Kalimantan become tinder: the 1997–98 El Niño event burned millions of hectares of Indonesian forest and peat and forced the largest rice imports in the country’s history. ⁵ Indonesia and the Philippines are, respectively, the world’s first- and second-largest rice importers in a bad year. Their bad year has already started.

India’s southwest monsoon which is the single most important weather system for human food security on Earth, watering the kharif rice, pulse, and oilseed crops on which 1.4 billion people depend is statistically reduced in strong El Niño years. The relationship is probabilistic, not mechanical; monsoons have defied El Niños before. But the monsoon now underway is running against the strongest Pacific heat forcing ever forecast, and the last time an El Niño of merely ordinary strength developed, in 2023, India’s response to a modest monsoon shortfall was to ban the export of non-basmati rice within weeks which sent shockwaves through the global rice supply. ⁶ India alone accounts for roughly 40 percent of the world’s traded supply.

Australia’s wheat belt faces its canonical El Niño outcome: a hot, dry austral spring landing precisely on the grain-fill and harvest window of the 2026–27 crop, in a year when the world has no American surplus to fall back on.⁷

Southern Africa is where the arithmetic turns cruelest. The region’s single maize season grows from December through March, the exact months of the forecast peak of the El Niño event. In 2015–16, a far weaker event than the one now projected, the drought that followed was southern Africa’s worst in 35 years: 40 million people became food-insecure, national disaster declarations were issued across the region, and maize harvests in Zimbabwe and Malawi fell by nearly half.⁸ The 2023–24 event repeated the pattern and again Zambia, Zimbabwe, and Malawi all declared national drought disasters.⁹ The season that begins this December will be planted by farmers who, thanks to the Hormuz fertilizer shock, are applying less nitrogen than at any time in a decade, into soil that the models say the rain will not reach.

Central America’s Dry Corridor including Guatemala, Honduras, El Salvador, Nicaragua loses its primera and postrera maize and bean seasons to El Niño droughts with grim regularity; the 2015 event left 3.5 million people there needing food assistance and helped drive a wave of northward migration.¹⁰ Northeast Brazil’s smallholder belt faces the same equation on a different calendar.

In contrast, El Niños cause other places to drown rather than to burn. The Horn of Africa’s October–December short rains typically come in torrents in El Niño years that cause flooding that destroys standing crops, drowns livestock, displaces communities, spreads cholera, and creates the wet breeding grounds from which desert locust outbreaks have historically erupted. Coastal Peru and Ecuador face the floods that gave El Niño its name, it also causes the collapse of the Peruvian anchoveta fishery, the largest single-species fishery on Earth and the anchor of the global fishmeal supply that feeds farmed fish, poultry, and hogs. When the anchoveta disappear, as they did in 1997–98, feed costs rise everywhere.¹

¹Figure 1. The harvest calendar in the crosshairs: canonical strong-El Niño impact windows for the world’s most exposed food-producing regions, July 2026 through December 2027, against the forecast November–January peak. Teleconnections are probabilistic, not certainties — but this is the pattern every major event since 1877 has broadly followed.

The Rice That Won’t Be Planted

Every staple has its own exposure to the effects of El Niño, but rice is where El Niño’s geography and humanity’s geography overlap most completely. Rice is the primary calorie source for more than 3.5 billion people. It is grown, overwhelmingly, in precisely the monsoon Asia that El Niño dries out. Unlike other crops only about a tenth of production is traded across borders as most rice is consumed is consumed in the country where it is grown. This means small production shortfalls produce large price increases, and large increases in price can produce panic. ¹²

The panic has a playbook, and the world has already experience rice market panic twice this century. In 2007–08, export restrictions cascading from one rice producer to the next tripled world prices in six months without any global production shortfall at all. In 2023–24, a moderate El Niño was enough to trigger India’s export ban and push rice prices to fifteen-year highs. The event now forecast is not moderate. If the El Niño causes the monsoon to be less than average or fail, and Southeast Asia’s rice paddies get late or insufficient monsoons, the question is how fast and what happens to Indonesia, the Philippines, Bangladesh, and the import-dependent nations of West Africa when they do.

In a global food system where a handful of export prices set the reference for everyone, having countries issue export bans will impact prices all over the world.

Three Shocks, One Table

What makes 2026 different from 1997 or 2015 is not only the size of the forecast. It is what the forecast is landing on.

The first shock came through a 21-mile strait. The closure of Hormuz in February severed a fifth of the world’s traded nitrogen fertilizer from its markets, sent urea prices up more than 60 percent, and guaranteed that farmers from Iowa to Uttar Pradesh would apply less nitrogen this year which will cause yield losses that arrive, on roughly a one-season lag, exactly as El Niño’s droughts do.¹³ A smallholder who cannot afford fertilizer loses 40 to 60 percent of her yield in a normal rainfall year.¹⁴ The models say this will not be a normal rainfall year.

The second shock is already in the ground. Sixty-one percent of the contiguous United States is in drought. The U.S. winter wheat harvest is only 1.561 billion bushels, the smallest since 1972. The American cattle herd is the smallest it has been since 1951 mean that the country that has served as the world’s agricultural shock absorber for eight decades is entering this event with no slack of its own.¹⁵ World grain reserves are the buffer between a bad harvest and a hungry year, and they are being drawn down even before the El Niño harvest failures begin.

The third shock is the ocean. Each of these crises would be manageable alone. The fertilizer shortage could be absorbed by a good growing year. The American drought could be offset by strong harvests abroad. An El Niño could be cushioned by full granaries and cheap inputs. Instead, each has arrived to find the others already there.

“A food system already starved of fertilizer and parched of rain is about to be struck by the strongest ever El Niño forecast. Any one of these is a crisis. All three at once is something the modern food system has never had to survive.”

Figure 2. The transmission chain from sea surface temperature to food insecurity. Global temperature lags the Pacific by three to five months; harvests lag by a season; prices lag harvests; hunger lags prices. The worst of what is now forecast lands on the world’s tables in 2027 and the lean seasons of early 2028.

What It Means in America

Honesty requires a complication here, and this publication has never shied from one: for parts of the drought-stricken American Southwest and Southern Plains, El Niño is not the villain of this story. A strong event typically shifts the winter storm track south, delivering above-normal cool-season precipitation across the southern tier from California to Texas. After six years of drought stress in the Southern Plains, a wet winter would be an unambiguous mercy that will recharge soil moisture ahead of the 2027 winter wheat crop and offering rangeland its first real drink since 2024. Credit where credit is due: if the pattern holds, some American farmers will owe this El Niño a debt.¹⁶

But no American eater should mistake regional rainfall for national immunity, for three reasons.

First, the price of food in an American grocery store is set in a global market. When Australian wheat fails and India restricts rice and southern Africa’s maize collapses, U.S. commodity prices rise regardless of the weather in Kansas, not because American grain is scarce, but because American grain traders sell into world prices. That transmission chain does not move at the speed of a headline. It moves at the speed of a growing season. But it moves, reliably and historically, to the consumer’s receipt.¹⁷

Second, the inputs. The anchoveta collapse and a global feed-grain squeeze land on a livestock sector already at a 75-year inventory low, with ground beef already migrating from staple to luxury. Beef prices were projected to rise 6.3 percent in 2026 before this forecast existed. And El Niño winters, for all their southern rain, raise flood risk across California’s Central Valley, the source of a third of America’s vegetables, where the line between drought relief and levee failure has always been thin.

Third, and most important: the Americans with the least room to absorb any of this. The United States entered 2026 with 47.4 million people, that is one in eight Americans already food-insecure, with the lowest-income fifth of households already spending nearly 30 percent of their budgets on food, and with Congress still weighing more SNAP cuts that would strip benefits from up to 8 million people.¹⁸ Every percentage point of El Niño-driven food inflation that arrives in 2027 will land on families who did not cause a war in the Gulf, did not cause a megadrought, and did not warm the Pacific.

What the Last Great El Niños Did

If the forecast holds, 2026–27 will join a short and terrible list, and it is worth remembering what the previous entries on that list actually did.

The 1877-78 El Niño was until this year, arguably the strongest ever observed caused the collapse of the monsoons of India and the rains of northern China and northeastern Brazil simultaneously. The famines that followed, amplified catastrophically by the colonial and market policies of the era, killed tens of millions of people. Historians call them the Late Victorian Holocausts. ¹⁹ The 1982-83 El Niño brought Australia’s worst drought of the century and Peru’s worst floods. The 1997-98 El Niño killed an estimated 23,000 people, caused some $40 billion in losses, set Indonesia’s forests alight, and broke the anchoveta fishery. ²⁰ The 2015-16 El Niño left 60 million people in need of humanitarian assistance across four continents which was the largest El Niño response operation ever mounted, and one the UN itself judged to have started too late.²¹

Figure 3. Peak intensity of the great El Niño events since 1877 (era-adjusted Niño 3.4 anomaly) and their human consequences, against the 2026–27 multi-model forecast median of 3.6°C. The whisker spans the middle 80 percent of the 667-member forecast ensemble — the bottom of which grazes the all-time record.

Two things must be said about the above chart, and the first is a caveat this publication insists on: the models have never been verified with an El Niño of this magnitude. No seasonal forecast system has ever predicted, and then been graded against, a 3.5°C El Niño, because one has never happened. Fourteen models agreeing is reassuring; it is not proof. ²²

The second thing is that the caveat cuts both ways, and offers less comfort than it appears to. The deaths in that history did not scale gently with the temperature of the water. They scaled with the poverty, the debt, the conflict, and the policy failures the water found when it arrived. By that standard, a world with 333 million people already in acute food insecurity before this year began, humanitarian funding in generational collapse, fertilizer severed and food reserves very low, this El Niño is arriving to more dry tinder and much less of a cushion than El Niños found in 1997 or 2015.²³

The Window That Is Still Open

There is one merciful fact buried in this forecast: El Niño is the most predictable large-scale climate shock on Earth. A hurricane gives you days. A flash drought gives you weeks. This event has given the world six months of warning before its peak and nine to twelve months before its worst food-security impacts arrive. Based on 150 years of history we have a likely schedule of where the rain will fail and when and where the harvests will miss. Famine after El Niño is the most foreseeable disaster in the humanitarian catalogue. Which means that every escalation from hunger to famine in 2027 will be, quite literally, a policy choice made in 2026.

“The cruelest thing about the hunger now forecast is that it is forecast. Every famine that follows an El Niño is a disaster the world watched coming for a year and chose not to proactively respond to.”

What is required is not incremental adjustment. It is dramatic, coordinated action on four fronts, taken while the window for action is open before the widespread hunger and famines occur.

First, fund the response before the failure, not after it. Anticipatory action including cash, seeds, drought-tolerant inputs, and pre-positioned food released on forecast triggers rather than on famine declarations, cost a fraction of late-stage emergency response and saves lives an emergency response cannot. The 2015–16 event proved the cost of lateness; the World Food Programme and FEWS NET have spent the decade since building the trigger systems to do better. Those systems now sit inside a U.S. humanitarian budget that has collapsed from roughly $14 billion to $3.7 billion in a single year. ²⁴ That collapse must be reversed, this budget cycle, with El Niño anticipatory financing explicitly funded for southern Africa’s planting season which begins in December, not in some comfortably distant fiscal year.

Second, protect and expand SNAP and domestic nutrition programs. The food-price wave from this El Niño arrives in American grocery stores in 2027, stacked on the fertilizer, fuel and drought inflation already in the pipeline. Cutting the primary safety net between price volatility and hunger for the 42 million Americans now in need and the millions more who will be in need during the same eighteen months is not fiscal discipline; it is a decision to transfer the cost of a Pacific Ocean climate event which we now is coming onto the households least able to pay it.

Third, pass a 2026 Farm Bill built for volatility. American farmers will plant the 2027 crop, the one the world will desperately need, facing record input costs, exhausted balance sheets, and an El Niño winter that may deliver drought relief and flood damage in the same season. Disaster programs that pay two years late, and insurance built for Big Agriculture’s monocrops rather than the diversified farms most able to adapt, are not equal to the coming crisis. The Farm Bill must deliver for both farmer and the poor and working classes in America.

Fourth, keep the grain moving. The lesson of 2007–08 is that export bans are contagious and that hoarding, not harvest failure, turns shortage into famine. The G20’s Agricultural Market Information System was created after that crisis precisely so that governments could see real stocks and resist panic. ²⁵ Using it and pressing the major exporters, publicly and early, to commit against blanket bans will do more to contain a surge in crop prices and protect America’s and the world’s poor in 2027 than any single tonne of aid.

How to Watch It Come

This event will unfold in public, in real time, in open data. The same forecasts and monitors cited throughout this article are free to anyone. If you want to watch the ocean, the models, and the food system respond and use this information to hold our elected officials to account, these are the places to look:

• The ocean, daily: NOAA’s Climate Prediction Center ENSO page publishes the official weekly Niño-region SSTs and the ENSO Alert System status, and Climate Reanalyzer maps daily sea surface temperature anomalies as they happen.

• The forecasts, monthly: the IRI ENSO forecast page at Columbia University compiles the multi-model plume; the NOAA ENSO Blog translates each month’s diagnostics into plain English; and Australia’s Bureau of Meteorology issues its fortnightly Climate Driver Update.

• The seasonal rainfall outlook: the Copernicus C3S seasonal forecast charts show where the world’s models expect the rains to fail, three to six months ahead.

• The crops: USDA’s Crop Explorer tracks global crop conditions from satellite; the GEOGLAM Crop Monitor issues monthly consensus maps of crop stress; and the Agricultural Market Information System reports world grain stocks and export policies.

• The hunger: FEWS NET, the U.S.-created Famine Early Warning Systems Network, publishes country-by-country food-insecurity projections; FAO’s GIEWS tracks food prices and harvest alerts worldwide; and WFP’s HungerMap Live estimates acute hunger in near-real time.

• At home: the U.S. Drought Monitor updates every Thursday, and USDA’s monthly WASDE report is where global harvest failures first become official American numbers.

A 3.6-Degree Warning

The Strait of Hormuz is 21 miles wide, and its closure taught this country how much hunger can flow through a gap that small. The Pacific Ocean is 12,000 miles wide, and it is about to teach a larger version of the same lesson: that the abundance on which the wealthy world congratulates itself rests on rain falling where it has always fallen, on inputs arriving when they have always arrived, and on reserves that exist only until three shocks to global food supplies arrive in the same eighteen months.

The smallholder in Malawi planting unfertilized maize into a season the models have already condemned did not warm the Pacific. Neither the rice farmer in Luzon watching the paddies crack, the rancher in Oklahoma finally getting rain after he has already sent his herd to slaughter, the mother in Houston watching the price of ground beef chose this. But all of them are downstream of the same warm water, and all of them will pay for it in the currency the poor always pay in: skipped meals, sold assets, mounting debt, the quiet emergency that hunger always is.

What separates this crisis from every previous large El Niño event is that it is being forecast in public, in detail, by fourteen independent modeling systems, half a year before its peak begins. The 1877 famines arrived without warning. The 2015 response started late, and the UN has now said so. This El Niño is different. The heating water in the Pacific has delivered its warning and it has been evaluated with a precision no disaster in history has matched. Whether tens of millions of people go hungry and many people die in 2027 or whether the most well predicted catastrophe on Earth becomes the first one the world actually responds to on time, belongs as it always does to those in power. Whether they can be made to act while the ocean warms and before hunger unfold around the world is the question. You and we must act. Call your elected officials both state and federal today and tomorrow and demand action before the impacts of this El Niño cause hunger in your state, America and around the world.

A drought-cured wheat field stands under wildfire smoke — the season’s defining image on both sides of the Atlantic. (Illustration)

A fire does not have to reach the field to take the harvest.

—

The United States crossed into its 2026 wildfire season already on fire. By the second week of July, the National Interagency Fire Center reported that more than 38,500 wildfires had burned over 3.4 million acres nationwide which is a pace running roughly a third above the ten-year average, with the West’s peak months still ahead.¹ The Mediterranean was burning too, with fires active simultaneously from Portugal to Greece, a span of well over a thousand miles: across the European Union, satellites had already mapped more than 155,000 hectares of scorched land by early summer, well above the twenty-year norm, in a year following the worst fire season Europe has ever recorded.^{5 6}

The headlines, as always, follow the flames with headlines alarming the evacuations, the lost homes, the walls of orange advancing on a ridgeline. But the deeper story of a bad fire year is written more quietly, in the places that grow and raise our food. Fire does not need to reach a field to damage what grows there. It scorches rangeland that livestock depend on, smothers vineyards in smoke that ruins a vintage without singeing a single vine, drives the farmworkers who bring in the harvest indoors, and burns through the olive groves and animal pens that anchor rural economies. In 2026, on two continents at once, wildfire has become an agricultural event as much as a forest one and this article traces how this happens.

PART I · THE AMERICAN WEST

Rangeland, Smoke, and the Grapes That Absorb It

The American fire season opened not in the forests but on the grasslands. Much of the acreage burned early in 2026 was in the southeastern United States and the Plains of Nebraska, Kansas, Oklahoma where fast-moving grass fires raced across landscapes primed by a winter of drought and thin mountain snowpack.³ The 2025 drought had peaked at 36.65% of the country in D1 (moderate) drought or worse in late November, and the West entered 2026 in severe snow drought. On December 7, 2025, snow cover across the West was the lowest for that date in the 24-year satellite record leaving little of the snowmelt that normally keeps forests from igniting through the summer.⁴ Wildfire experts warned the nation was entering the season as a tinderbox.³

For agriculture, grass fires are livestock fires. They burn the rangeland and pasture that cattle and sheep graze, along with the fences, corrals, barns, and hay stores that ranching depends on. When fire tore through the Texas panhandle earlier in the season, the USDA moved quickly to open its disaster toolbox including the Livestock Indemnity Program for animals lost beyond normal mortality, emergency grazing authorizations on conservation land, and cost-share programs to replace fencing and haul feed and water to surviving herds.⁷ Those programs exist precisely because a rangeland fire’s damage outlasts the flames: a rancher who loses grazing ground and infrastructure faces a difficult year of bought feed and rebuilt fence line long after containment.

History sets the scale. In California’s recent mega-fire years, blazes ripped through national forests used for grazing and across the rangeland that ranchers manage, killing cattle and forcing producers to euthanize animals too badly burned to survive; a state legislative analysis documents destroyed fencing, structures, and livestock across those seasons.⁸ The individual losses are devastating even when, as economists note, a single state’s cattle inventory is too small a share of the national herd to move grocery prices.

The vineyard problem: damage without a flame

No crop illustrates wildfire’s indirect reach better than wine grapes. Grapevines themselves rarely burn since they are irrigated and green. In fact, vineyards often act as firebreaks, and even a smoke-affected vine recovers with no carryover to the next season.¹³ The threat is smoke taint: volatile phenols released when wood burns are absorbed straight through the grape’s permeable skin, then bind to sugars inside the berry. Months later, in the acidic medium of finished wine, those bonds can hydrolyze and release compounds that experts describe as tasting “like licking an ashtray.”^{9 10 11} A vineyard can stand untouched by fire and still lose its entire harvest to a plume that drifted overhead for a day.

“Without question, the threat of wildfire in many different ways is the greatest challenge of the day for the industry.”

— John Aguirre, President, California Association of Winegrape Growers(11)

The North Coast fires of 2017, 2019, and 2020 caused substantial grape losses in Sonoma, Lake, and Napa counties and made up the bulk of California’s agricultural fire losses in those years.¹² In Napa, lost vineyard acreage can average around $100,000 an acre, and smoke-affected red grapes that might have fetched close to $10,000 a ton often were not worth harvesting at all, according to a California legislative analysis.⁸ The USDA’s Agricultural Research Service now funds a sustained program of smoke-exposure research in wine grapes. This work that has, for example, identified grape-microbiome bacteria able to break down the taint compound guaiacol.⁹ At the same time, crop-insurance standards still lean on older laboratory markers, leaving a gap between what science can now detect and what growers can be compensated for.¹²

The people who bring in the harvest

There is a human dimension that rarely makes the fire maps. Peer-reviewed research finds that farmworkers face disproportionate wildfire-smoke exposure while performing heavy outdoor labor when the PM2.5 air-quality index turns “unhealthy,” often with underlying health risks and limited health-care access. To respond to this, California made permanent a Cal/OSHA rule requiring employers to supply NIOSH-approved respirators once the AQI passes 150.¹⁴ In 2024, CDC’s NIOSH issued the first federal hazard review devoted to wildland-fire smoke among farmworkers and outdoor workers, and the American Lung Association notes agricultural workers are far more likely than other workers to die of heat-related illness, a risk that compounds with smoke.^{15 16} Lost workdays ripple into lost harvest, and one of wildfire’s larger effects on agriculture may simply be the difficulty of assembling the workforce a food system needs.

For direct field damage, the picture is more nuanced than headlines suggest. A peer-reviewed review of smoke-aerosol impacts finds that thin smoke can slightly increase corn photosynthesis by scattering light into the canopy, while heavier or sustained smoke and the ozone that wildfires generate reduces yields. Ozone from wildfires alone is estimated to cut U.S. corn, wheat, and soybean output by several percent.¹⁷ Recent work points both ways: a Kansas State analysis linked smoke to reduced soybean yields on the northern Plains, while Purdue researchers found a small corn benefit under certain conditions.¹⁷ The lesson is that not every smoky summer is a catastrophe for the Corn Belt, and precision matters as much as alarm.

PART II · THE MEDITERRANEAN

Olive Groves, Herds, and Bees Turned to Ash

Europe enters 2026 in the shadow of a record. The 2025 season was the EU’s most destructive fire season ever recorded: more than one million hectares burned within the bloc, nearly double the long-run average, with Germany, Spain, Cyprus, and Slovakia all setting all-time records, and roughly 39% of the burned area falling inside the Natura 2000 network of protected sites.⁶ 2026 has picked up where that left off. By early July, hundreds of firefighters were battling blazes in Portugal, Greece, Spain, and France simultaneously; more than 10,000 people were evacuated as a single wildfire tore through southern France, and Spain alone had recorded 14 “major” fires of over 500 hectares according to EFFIS and Spain’s environment ministry.^{18 19}

In the Mediterranean, farmland and fire are woven together. Much of what burns is the mosaic of olive groves, orchards, pasture, and small livestock farms that defines the rural south. The Hellenic Fire Service estimates that about 85% of Greece’s wildfires are caused by human negligence, including sparks thrown by agricultural machinery, discarded cigarettes, and outdoor fires.¹⁸ Fire is not only a threat to farming here; farming is one of the ways fire starts.

A single fire, an entire farm

The toll from fires in Europe is best measured up close. When a wind-driven wildfire swept through Akraifnio in the Boeotia region of central Greece in late June 2026, it destroyed a major livestock farm in minutes: an entire cattle pen was consumed, the farm’s machinery lost, and a herd of roughly 60 calves and a flock of sheep killed. The same blaze burned through extensive olive groves and pistachio orchards, deepening the economic wound to local farmers already living at the margins.²⁰ “The fire moved incredibly fast,” a resident told a local agency. “Many olive trees and pistachio trees burned.”²⁰

THE COMPOUNDING LOSS
Farm fires cascade beyond the visible damage. After earlier Mediterranean fires, one Greek regional authority calculated an urgent need to feed 44,000 surviving animals whose pasture had burned, and to sustain 21,000 beehives whose entire foraging landscape was gone. A beekeepers’ association warned that if bees couldn’t forage to prepare for winter, “we will have no bees in the spring.” This will be a pollination gap that reaches into next year’s harvests across the region.²¹

Older Mediterranean fire years show how far the losses run. Reporting on recent seasons documents a single Limassol-district blaze in Cyprus in 2025 that killed roughly 100 livestock across 14 farms and destroyed thousands of hectares of agricultural land, and fires in Turkey’s productive olive-growing provinces that reduced well over a hundred thousand hectares of forest and farmland to ash.²⁴ The pattern is structural, not anecdotal: peer-reviewed fire-risk modelling of Mediterranean landscapes finds that as unmaintained and abandoned farmland expands, the modelled burn probability of both settlements and permanent crops such as olive orchards rises with it.²³ And olive groves are not annual crops that regrow in a season, a mature grove destroyed is a generation of income and heritage gone at once.

PART III · THE MECHANISMS

Why a Fire You Never See Still Reaches Your Plate

Strip away the flames and four distinct pathways connect a distant wildfire to the food supply. Understanding them explains why “the fire didn’t reach the farm” is rarely the end of the story.

Direct destruction. Wind-driven fire burns crops, orchards, pens, barns, fences, irrigation lines, and the animals themselves. Even irrigated crops offer no guarantee according to a legislative analysis of California’s fires documents blazes burning through orchards and vineyards and destroying rangeland fencing and structures, with tree- and vine-crop losses valued per acre far above annual row crops.⁸ For tree and vine crops, a burned grove or vineyard is a capital loss measured in decades, not one lost harvest.

Smoke and taint. Wine grapes are the clearest case, absorbing volatile phenols through their skins to produce ashy, unsellable wine from vineyards fire never touched.^{9 10} The science of detecting and treating smoke damage is now advancing faster than the insurance rules meant to cover it.¹²

Rangeland and forage collapse. Grass fires destroy the grazing land and stored feed that livestock depend on, forcing ranchers to buy feed, relocate herds, or cull animals, this is the reason USDA disaster programs center on forage, fencing, and livestock indemnity.^{7 8} In the Mediterranean, the same dynamic strands surviving herds and bees without pasture or forage the moment a landscape burns.²¹

Labor and logistics. Smoke drives farmworkers to reduce or halt outdoor work. California’s mandatory respirator rule and CDC/NIOSH’s federal hazard review are a start at dealing with this health hazard, but do not deal with the lack of workers needed during a fire. A harvest that can’t be picked, moved, or processed on time is a loss even if every plant survives. In addition, burned rural roads and destroyed processing and storage cut farms off from markets.^{14 15}

A NOTE ON PROPORTION
Not every smoky summer is a catastrophe for food. Peer-reviewed work finds thin Corn Belt smoke can even modestly aid corn by diffusing light, with the clearer yield penalties coming from heavier smoke, ozone, and soybeans rather than a uniform collapse.¹⁷ The serious, documented damage clusters in specific places such as rangeland in a fire’s path, vineyards downwind of heavy smoke, olive groves and livestock farms in the Mediterranean fire zone, rather than spreading evenly across all of agriculture. Precision matters more than alarm.

PART IV · WHAT COMES NEXT

Living Fire Season by Fire Season

The forecasts offer only guarded relief. NIFC’s outlook keeps above-normal fire potential across much of the West through the summer, with lightning ignitions expected to give way to human-caused starts as the season wears on.² In Europe, EFFIS warns of very extreme fire-danger conditions across a broad band of the west and center of the continent, precisely where the season’s worst damage tends to concentrate.⁵ Peer-reviewed research increasingly frames the Mediterranean crisis less as a failure of firefighting than as a slow-building failure of land management including rural abandonment and the decline of grazing leaving fuel to accumulate on hillsides that farmers and herders once kept in check.²²

What is clear is that 2026 has not delivered a single wildfire so much as a season defined by fire, and that its reach extends well past the burn scar, into rangeland that can’t feed a herd, vineyards downwind of a plume, olive groves generations in the making, and the workers who bring in what survives. The damage is uneven and often indirect, which is exactly why it is so easily missed: a fire can leave a farm standing and still take its harvest, its herd, or its year.

As wildfire settles into a permanent feature of summer on both continents, the tools above are how growers, workers, and eaters alike can watch it coming and how the rest of us can understand that when the West and the Mediterranean burn, some of what is lost is the food they grow leading to crop loss and adding to global hunger.

A Nation Cooking on Both Land and Sea

The United States rang in its 250th birthday under a heat dome that would not move. By the Fourth of July weekend, more than 160 million Americans were living under heat alerts, with the National Weather Service placing over 165 million people across the Midwest and East at risk of “major” or “extreme” heat-related illness.¹

The records fell fast. Central Park hit 100°F for the first time in nearly 14 years.² Washington, DC reached 102°F, breaking a high-temperature record that had stood since 1872.³ By the time the heat dome finally began to loosen its grip, the 2026 North American heat wave had been blamed for at least 23 deaths, strained power grids to a record demand level, and forced the cancellation of Independence Day parades in Washington, Philadelphia, and beyond.⁴

That single, headline-grabbing heat dome was only the visible peak of a much longer season. Since March, a string of overlapping heat waves and drought events has been quietly rewriting the numbers for American agriculture. And a thousand miles offshore, a marine heatwave has spent nearly a year warming the waters of the West Coast, threatening to repeat a disaster that has already reshaped a major American fishery once this decade. Together, the two events show how thoroughly heat, on land and at sea, has come to define what growers and fishing communities are up against in 2026.

Increase in the percentage of the global population exposed to heat stress from the 1970s to the last 10 years (2015–2024).

The Geography of Loss: Wheat, Drought, and a Season Without Relief

Unlike a single dramatic heat dome, the damage to American farming this year has accumulated in layers, one weather system at a time.

It started early. Between March 15 and 21, an unseasonable heat wave shattered hundreds of daily temperature records across the western and central states, with readings nearing 110°F in the desert Southwest. The early heat accelerated evapotranspiration, deepening soil moisture deficits and driving up irrigation demand in regions already dependent on shrinking snowpack.⁵ By late March, temperatures were running more than 10°F above normal across much of the West and Plains, the USDA reported, and the Sierra Nevada snowpack, a critical source of irrigation water for California, had dropped below 20% of normal, creating a serious threat to the state that grows more than a third of the nation’s vegetables.⁶

By mid-May, the toll on the country’s wheat crop was becoming clear. USDA data showed that 32% of US winter wheat acreage would go unharvested in 2026, the second-highest abandonment rate since the Dust Bowl era, as extended heat and drought stress pushed fields past the point of recovery.⁷ Extreme to Exceptional Drought covered half of Nebraska by June, with Colorado, Oklahoma, Wyoming, New Mexico, and South Dakota all reporting severe moisture stress.⁸ Even with the U.S. crop shrinking, several major competitors still posted historically large harvests: Russia had its fourth-largest crop ever, while Australia, Canada, and Kazakhstan all had smaller crops that remained historically large. Record global carry-in stocks also gave the market a buffer against the U.S. shortfall which kept prices low, so the U.S. wheat producers that could harvest crops got a lower price than normal. The 2025/26 season-average U.S. farm price was projected at just $5 per bushel, with December 2025 futures hitting $4.88 in October 2025 which was a multiyear low.

The heat kept coming through the growing season. A USDA report from early June described extreme heat across the Plains compounding with severe thunderstorms and worsening dryness in the South, even as Corn Belt states pushed on with planting; more than 90% of intended corn acreage was in the ground in nearly every Midwestern state by early June.⁹ Then came the July heat dome itself, which drove up irrigation and energy costs for the specialty crops, fruits, and vegetables that depend on it most, adding new pressure to farm margins already squeezed by input costs.¹

Livestock producers have faced a parallel squeeze. Heat stress hits animals at lower temperature thresholds than it hits crops, and pigs and poultry, which cannot cool themselves as efficiently as cattle, are especially vulnerable, according to a joint 2026 report from the UN Food and Agriculture Organization and the World Meteorological Organization. The consequence: reduced growth, lower dairy yields, and in severe cases, organ failure.¹⁰

“Extreme heat is increasingly defining the conditions under which agrifood systems operate.” — WMO Secretary-General Celeste Saulo

The Ocean Also Boils: A Marine Heatwave Off the West Coast

While the heat dome was making headlines on land, a separate and less visible heat event has been building at sea. A marine heatwave has dominated the waters off the US West Coast since the summer of 2025, and NOAA scientists say it is only the third time on record that such a large stretch of coastal ocean has stayed unusually warm for so long, through an entire winter, without being linked to an El Niño event.¹¹

At its peak in September 2025, the heatwave rivaled the size and surface temperatures of the infamous 2013–2016 event known as “the Blob,” and the northeast Pacific briefly reached its highest average temperature ever recorded, about half a degree warmer than any prior measurement.¹² The current event has raised West Coast waters roughly 3 to 4°F above normal.¹¹

The immediate worry for fisheries is not the warm water itself, but what it can trigger: harmful algal blooms. These blooms can sicken marine mammals and force the closure of shellfish fisheries, particularly recreational ones, hitting coastal economies directly. A bloom in 2025 arrived unusually early and killed hundreds of California sea lions, dolphins, and seabirds, and NOAA scientists are watching closely for a repeat.¹¹ So far, this heatwave has not penetrated as deep into the water column or lingered as close to shore as the original Blob, limiting its ecological damage, and NOAA’s forecasts suggest the warm water may dissipate in the coming months as it mixes with cooler water below.¹¹

History gives that watchfulness some weight. The 2013 Gulf of Alaska marine heatwave restricted Pacific cod spawning habitat so severely that the cod population fell by roughly 100 million fish; when the population still hadn’t recovered by 2020, the federal government closed the commercial fishery for the first time in its history.¹³ More recently, a 2023 West Coast marine heat wave caused such a sharp drop in albacore catch rates that authorities declared a fisheries disaster and the industry sought federal relief for that season’s losses.¹⁴

The Mechanisms Beneath the Numbers

The headline statistics: abandoned wheat acreage, a warming Pacific, only hint at what is actually happening inside plants, animals, and the ocean itself. A growing body of research from federal agencies, international bodies, and peer-reviewed journals lays out the underlying physiology, and it helps explain why heat this persistent does more damage than a single hot afternoon ever could.

Crop Biology: The Nighttime Temperature Penalty

Daytime heat is not the whole story for crops. A large and growing body of research points to nighttime warming as an especially destructive force, because it prevents plants from resting. Warm nights accelerate a plant’s “dark respiration,” the metabolic process that burns through the sugars and starches a plant has built up during the day, leaving less available for grain and seed development. A recent peer-reviewed synthesis of wheat trials found that grain yield has been measured to fall by roughly 1.9% for every 1°C rise in nighttime minimum temperature, with some studies reporting penalties as high as 10% per degree in spring wheat and 12.9% per degree in winter wheat.¹⁷ Field trials in Australia went further: raising nighttime temperatures from 15°C to 20°C during the reproductive stage of wheat produced up to a 40% yield loss, driven by higher floret sterility and lower grain weight.¹⁸

The mechanism is well documented at the cellular level: elevated night temperatures increase respiratory carbon loss, depleting the non-structural carbohydrate reserves that crops depend on to fill grain, a dynamic described in a peer-reviewed synthesis on respiratory control of crop yield under heat stress.¹⁹ Layered on top of that is the drought dynamic the USDA has already flagged this season: when soil moisture runs short, plants lose their main defense against heat, transpirational cooling, which can push leaf and canopy temperatures still higher and compound the damage.⁸

Livestock: When Nights Don’t Cool Down

Livestock face a related but distinct problem: unlike people, pigs cannot sweat, and both pigs and poultry rely heavily on panting to shed body heat, a far less efficient cooling mechanism. The USDA’s Agricultural Research Service estimates that heat stress already costs the US swine industry roughly $481 million a year in lost revenue, even before accounting for the kind of extended, multi-week heat this season has brought.²⁰ For poultry, research compiled by the European Food Safety Authority and cited in recent agricultural engineering studies puts the ideal temperature range at 20–25°C, with production losses beginning above roughly 30°C.²¹

USDA-ARS researchers who study livestock heat stress have long emphasized that the ability of animals to recover overnight is what determines whether a heat event becomes dangerous, and threshold temperature limits for swine, cattle, and sheep are central to how ARS models predict risk.²² When overnight lows stay elevated, as they have through much of this season’s heat domes, that recovery window narrows or disappears. The production consequences are measurable: an Australian study of dairy cattle found that as heat stress intensity rose, daily milk production dropped by as much as 14%, alongside rising respiration rates and body temperatures.²³

The Ocean’s Version of Heat Stress: Oxygen and Range Shifts

Marine heatwaves inflict a version of the same nighttime-recovery problem, but through ocean chemistry rather than animal physiology. Warmer water simply holds less dissolved oxygen, and NOAA Fisheries scientists on the West Coast track a hypoxia threshold of roughly 1.4 milliliters of oxygen per liter, below which bottom waters become lethal to many fish and invertebrates; hypoxia of this kind is already a recurring summer feature of the shelf off Oregon and Washington.²⁴ In 2021, NOAA-supported researchers measured near-bottom hypoxic water spanning nearly half the continental shelf inshore of the 200-meter line, the most extensive event on record, and found a long-term trend toward lower oxygen levels dating back to 1950.²⁵

For fish, the physiological bind is direct: warmer water raises their metabolic oxygen demand at the same time that less oxygen is available, a mismatch that peer-reviewed research on marine heatwaves describes as a key driver of die-offs and reduced thermal tolerance in affected species.²⁶ The longer-term response for mobile species is to leave. A NOAA Fisheries-funded study published in PLOS ONE projected that hundreds of US fish and invertebrate species, including economically significant ones such as lobsters, will continue shifting northward as the ocean warms, a process NOAA scientists say is already underway at different rates in different regions.²⁷ For fishing fleets, that migration collides with a management system built around fixed geographic quotas, forcing longer transits, higher fuel costs, and, in cases like Atlantic mackerel, international disputes over who gets to catch a stock that has moved into someone else’s waters.²⁸

A Strained Nexus: Water, Energy, and Food Compete for the Same Resource

Heat does not stress agriculture, energy, and water systems separately, it stresses all three at once, through what researchers call the food-energy-water nexus. Thermoelectric power plants require large volumes of water for cooling, the same reservoirs and rivers that irrigation-dependent farms are drawing down harder this season, and the US Department of Energy has long identified this competition as a growing vulnerability under climate stress.²⁹ The strain runs in both directions: research on the water-electricity nexus in the Midwest has found that a 1°C rise in cooling water temperature can reduce a power plant’s generating capacity by roughly 0.15% to 0.5%, precisely when demand for air conditioning is peaking.³⁰

It is this compounding, cross-sector pressure, on crops that cannot cool at night, on livestock that cannot sweat, on fish running out of oxygen, and on a power grid competing with farmers for the same water, that is pushing discussions in Washington toward a Farm Bill with stronger climate resilience provisions and modernized crop insurance frameworks, even as the current bill remains unfinished.⁷

Who Pays When the Weather Turns

The costs of a hot season like this one land unevenly. Irrigation-dependent specialty crop growers face rising energy and water bills on top of already elevated input costs. Ranchers face the prospect of higher feed costs if pasture quality keeps declining. Wheat farmers who abandoned nearly a third of the nation’s winter wheat acreage face tightening supply and a growing reliance on crop insurance and federal disaster support just to stay solvent through the season.⁷

On the coast, the exposure is different but no less real: recreational and commercial shellfish operators face the possibility of sudden closures if a harmful algal bloom takes hold, and communities built around fisheries like Pacific cod and albacore have already seen, within the last several years, how quickly a warm ocean can turn into a declared disaster.¹³¹⁴

The human toll of the July heat dome itself was also concrete and immediate: at least 23 deaths, emergency rooms reporting “extremely high” rates of heat-related visits, and hundreds of thousands of homes without power at points during the event, as the grid strained under record demand for air conditioning.¹⁵⁴

What Comes Next

The USDA’s outlook, as of its most recent Agricultural Weather Highlights, calls for above-normal temperatures to persist across much of the West and Deep South, with cooler-than-normal conditions offering some relief to the northern Plains, Midwest, and Northeast.⁵ At sea, NOAA’s forecasts suggest the marine heatwave may weaken in the coming months as surface waters mix with cooler water from below, though scientists caution that whether enough warm water and nutrients persist to fuel another harmful algal bloom remains an open question.¹¹

None of this guarantees smooth sailing. As one farm economist put it during an earlier heat-driven scare, growers are still “living off surface moisture, rain by rain, week by week,” and the same could now be said of a fishing industry watching the Pacific for the next bloom.¹⁶

What is clear is that 2026 has not delivered a single heat wave so much as a season defined by heat: on the plains, where wheat cracked and went unharvested; in the reservoirs and snowpack that irrigation depends on; and in an ocean that has now spent the better part of a year running warmer than it should. The story of American food this year is being written twice over, once in the fields and once beneath the waves, by the same rising temperatures.

Climate change is hitting America’s food production and it is time that we pay real attention because lower crop yields and fisheries captures result in higher prices and push more Americans into food insecurity just as the government dismantles America’s safety net.

Nearly a year after President Trump signed the “One Big Beautiful Bill” into law on July 4, 2025, its consequences are no longer theoretical for Massachusetts families.¹ They show up as a busy signal. They show up as an expired document nobody can resubmit in time. They show up as a mother standing in a food bank line who, months ago, had a working SNAP card.

Nationally, more than 4 million people have dropped off SNAP since the law’s enactment, that’s nearly 10% of the entire caseload gone in under a year.² Massachusetts is not merely keeping pace with that national unraveling. It is outpacing it.

In the twelve months ending this past March, roughly 155,000 people fell off Massachusetts’ SNAP rolls, including an estimated 54,000 children.³ A separate accounting, drawn from state data obtained by the Massachusetts Law Reform Institute, found the decline moving at nearly double the national rate - an 80,000-household collapse that includes close to 50,000 children, among them families who never should have lost their benefits at all.⁴

The system meant to catch them is instead the thing failing them. Massachusetts’ SNAP hotline now fields an average of 20,000 calls a day, answered by just 645 caseworkers.⁵ More than three out of every four of those calls are disconnected before anyone can pick up.⁶

“Because of policies passed by President Trump and Congress, thousands of Massachusetts residents are being kicked off SNAP.”
— Spokesperson, Massachusetts Department of Transitional Assistance⁷

The Machinery Behind the Collapse

This is not a single glitch. It is several federal changes, arriving at once, each one tightening the same door.

Work requirements have expanded to groups never covered before. Adults 55 to 64. Parents of teenagers 14 and older. People who, a year ago, were exempt and are now required to document 20 hours of work a week or lose benefits after three months.⁸

Immigrants are being removed outright. Massachusetts has already begun cutting off SNAP for up to roughly 10,000 legally present immigrants who have lawful status but now are now locked out of a program that once served them.⁹

The state is being handed the bill. Beginning in fiscal year 2027, Massachusetts must absorb a dramatically larger share of SNAP’s administrative costs, rising from 50% to 75% and, for the first time in the program’s history, states will owe a share of benefit costs tied to their payment “error rate.”¹⁰ That error rate overwhelmingly reflects paperwork mistakes, not fraud. Every dollar the state fears owing is a dollar of pressure pushing eligibility workers to find reasons to say no.

Recertification now happens twice as often. Many households must renew their eligibility every six months instead of once a year. this is doubling the number of interviews, documents, and chances for the system to drop them.

Trump administration officials, including Agriculture Secretary Brooke Rollins, have credited the falling caseloads to a stronger economy and reduced fraud.¹¹ Harvard public health policy professor Sara Bleich rejects that framing outright: the economy has not measurably improved since the law passed, she notes, and the real drivers are the law’s new eligibility hurdles and the administrative wall states can’t staff fast enough to meet.¹²

The Human Cost of a Busy Signal

Merideth Lively did everything right. A routine recertification. A scheduling mix-up. A caseworker’s error in the paperwork. What followed was two months of unanswered calls, a malfunctioning app, and repeated hours-long visits to a DTA office before benefits were finally restored.¹³ “It was like a process that should have been totally normal and simple,” Lively said. “I never should have been cut off.”¹⁴

This is happening against a backdrop already stretched thin. An estimated 40% of Massachusetts households experienced food insecurity in 2025 before the deepest cuts had even taken hold.¹⁵ Roughly 7,200 adults newly subject to strict work rules are at risk of losing SNAP this spring alone if they cannot reach DTA in time to prove they qualify.¹⁶ Advocates at the Massachusetts Law Reform Institute estimate that as many as 100,000 residents statewide could ultimately be at risk under the eligibility changes now working their way through the system.¹⁷

“We can’t have people who are struggling to put food on the table and eligible for this program losing access to it simply because they can’t get through.”
— Massachusetts anti-hunger advocate¹⁸

MassHealth: The Larger Blow Still Coming

If SNAP is the crisis unfolding now, MassHealth is the crisis on the calendar. And Massachusetts, of all fifty states, is positioned to be hit hardest.

A joint analysis by the Robert Wood Johnson Foundation and the Urban Institute found that once new Medicaid work requirements and more frequent eligibility checks take full effect, between 99,000 and 202,000 Massachusetts residents could lose MassHealth coverage.¹⁹ No other state is projected to lose a larger share of its Medicaid rolls. Even the most conservative estimate in the report projects a 33% drop in expansion enrollment.²⁰ MassHealth’s own internal projection, delivered by chief operating officer Elizabeth LaMontagne, lands even higher than outside estimates: roughly 175,000 residents are expected to eventually lose coverage.²¹

The mechanism mirrors what has already gutted SNAP. Starting January 1, 2027, MassHealth members age 19 to 64 in the Medicaid expansion group must work, volunteer, or attend a work program for at least 80 hours a month — or show at least $580 in monthly earnings — unless they qualify for an exemption such as caring for a young child or living with a disability.²² Eligibility will be rechecked every six months instead of annually. Retroactive coverage, the safety net that once covered care received before a member’s paperwork was finalized, will shrink to as little as one month for many adults.²³ Separately, up to 2,500 MassHealth members — refugees, asylees, and other lawfully present immigrants — are expected to lose comprehensive coverage this October because of their immigration status alone.²⁴

Massachusetts’ own demographics make the state especially exposed. Researcher Katherine Hempstead points out that the state’s Medicaid expansion population skews toward adults without children, who are less likely to qualify for exemptions, and that the state’s comparatively high minimum wage already pushes many workers just over the income line that would let them keep coverage under the new rules.²⁵ MassHealth is racing to link its systems to wage, veterans’, and student-enrollment databases to automate compliance checks, and the state has proposed roughly $30 million to build that infrastructure and hire additional staff.²⁶ Even so, officials concede plainly: not everyone will be automatically confirmed. Some members will have no choice but to track down and submit their own documentation, on their own initiative, or lose coverage.²⁷

Hospitals are watching nervously. If patients lose coverage and remain uninsured, the emergency care they still need doesn’t disappear — it just shifts onto hospital balance sheets, particularly at facilities serving low-income patients. UMass Memorial Health has already scaled back some services in anticipation of what’s coming.²⁸

“We are really committed to implementing these changes in the most thoughtful way that minimizes impact to the members and coverage, while, of course, maintaining that federal compliance.”
— Elizabeth LaMontagne, MassHealth Chief Operating Officer²⁹

A State That Shows the Nation What’s Coming

Massachusetts built one of the country’s more generous social safety nets that includes broad MassHealth eligibility, a robust ConnectorCare program, a SNAP system designed to reach more of the people who qualify for it.³⁰ That generosity is precisely why the “Big Beautiful Bill” is hitting the state so hard: the more people a state successfully enrolled before the law passed, the more people it now stands to lose.

What is happening in Massachusetts today faster-than-average SNAP losses, a disconnected hotline, a Medicaid program bracing for the steepest proportional drop of any state is not an aberration. It is a preview. As more of the law’s provisions phase in through 2027 and 2028, every state faces the same bind Massachusetts is living through right now: absorb the new administrative and benefit costs itself or let eligible families fall through the cracks of a system it cannot staff fast enough to run.

The question is whether the state, and the federal government that wrote these rules, can respond at the scale the moment demands with enough caseworkers, enough funding, and enough urgency to keep children fed and families insured while Washington shifts the bill onto the states least equipped to absorb it. The busy signal Adamary Olivas and Merideth Lively heard is still ringing in kitchens and DTA offices across Massachusetts tonight. Whether anyone in power picks up remains, as it always does, a choice.

Project Bread and the Make Hunger History Coalition are working with Governor Healy’s Hunger Task Force to respond to these federal cuts. They could use your help and your support.

A famine in the Americas should stop us cold. That it barely registers tells you how numb we have become to the acts of the Trump Administration and how quietly this crisis has been engineered.

Because it has been engineered. The hunger now deepening from Port-au-Prince to Khartoum to Cox’s Bazar is not a story of failed rains alone, or of war alone. It is the product of two forces colliding: the largest collapse of foreign aid ever recorded, and the most punishing climate shocks in a generation. Neither would be as lethal on its own. Together they are killing people who would otherwise still be alive.

Start with the collapse. In April, the OECD reported that official development assistance from the world’s wealthy donors starting with Donald Trump’s cancellation of UAID fell 23.1 percent in 2025. This is the steepest single year drop on record, dragging global aid back to where it stood a decade ago. The United States drove roughly three-quarters of that decline, cutting its own assistance by 57 percent as it dismantled USAID. Humanitarian aid specifically fell by more than a third.

This is not an accounting abstraction. Aid is load-bearing infrastructure. It is the clinic that treats a malnourished child, the seeds a farmer plants before a drought, the early-warning system that sees famine coming in time to move food. Pull it out, and you don’t just remove charity, you remove the shock absorber standing between a fragile community, the next disaster and unnecessary deaths.

The death toll is no longer hypothetical. A study in The Lancet projected that the unwinding of USAID could cause more than 14 million additional deaths by 2030, a third of them young children. The dying has already begun by early 2026, one year into the cuts, independent trackers attributed more than 760,000 deaths to cuts in aid, over half of them children. That number has continued to climb higher.

Now layer on the climate. In Sudan, where war and aid withdrawal have converged into the world’s largest hunger crisis, famine was confirmed in 2025 and has since spread; by February 2026, two more areas of Darfur crossed the threshold into starvation, making Sudan the country with more territory in active famine than anywhere on Earth. Famine is the most extreme level of food insecurity, defined by a severe and widespread shortage of food that causes widespread acute malnutrition, starvation, and death. It represents a catastrophic collapse in a population’s ability to access sufficient, nutritious food.

In the Horn of Africa, a failed rainy season has pushed nearly 26 million people across Kenya, Somalia, and Ethiopia into extreme hunger. Extreme hunger caused by a lack of food is formally defined as severe food deprivation or starvation. It is the physical and psychological distress caused by consuming fewer than 1,800 calories per day, leading to malnutrition, tissue breakdown, and an inability for the body to sustain normal functions.

In Somalia, aid agencies project that close to half of all children under five will need treatment for acute malnutrition this year. In Afghanistan, child malnutrition is hitting record highs as the WFP, its budget collapsing, can reach only a fraction of the 17 million people who need food. Even the Rohingya refugees in Bangladesh, who are stateless due to the genocide in Myanmar, who are barred from working, confined onto one of the most cyclone-battered coastlines on the planet, have watched their food vouchers from the World Food Programme be cut from $12.50 a month toward as little as $6, as the relief operation that sustains them fell to under a fifth of its funding.

The pattern is always the same. Climate change supplies the shock. The aid cuts remove the defense. And the people who did the least to warm the planet and have the fewest resources to survive it are caught in between and pay with their lives.

There is a final, quieter cruelty in all this: the cuts have taken our eyes. The same freeze that gutted food programs also crippled the surveillance networks that watch for famine. When the world’s authoritative hunger report appeared this spring, its authors warned that the apparent leveling-off of global hunger was partly an illusion because the analysis rested on the fewest adequately measured countries in a decade, with whole nations, including Ethiopia and its tens of millions in dire states, going uncounted. We are not only starving the response. We are making it so no one knows what is going on.

None of this had to happen, and none of it is irreversible. The single most important step is also the simplest: reverse the humanitarian cuts, and fast. The WFP says it needs roughly $13 billion this year just to reach the hungriest 110 million people. That is reaching only a third of those people in need. The WFP currently expects the wealthy countries to fund barely half that. In a global economy measured in the trillions, the sum required to keep millions alive is a rounding error. What’s missing is not money. It’s will. It is the courage to stand up to the evil foreign policy of Donald Trump and other wealthy nations.

The rest follows. Rebuild the early-warning systems and shield them from political whim, so we can at least see the next famine coming. Shift climate finance toward grants rather than loans, so that nations already drowning in debt aren’t asked to borrow their way through disasters they did not cause. Treat food aid and climate adaptation not as generosity but as what they are: the cheapest insurance a stable world has ever been offered and the best way to stop chaos.

Hunger does not stay where we leave it. It drives displacement; displacement drives instability; instability reaches, eventually, the comfortable capitals that imagined themselves insulated. The famine spreading across the global South is a test of whether wealthy nations will recognize a catastrophe of their own making while it can still be stopped.

It is being made by subtraction, one cut, one failed harvest, one shuttered clinic at a time. It can be unmade the same way. But only if we choose to look and act.

They were not exaggerating. As they wrote, famine was spreading across Sudan, which by February had more land in active starvation than anywhere on Earth. A different failed rainy season was driving nearly 26 million people toward catastrophe across Kenya, Somalia, and Ethiopia. Afghanistan’s child-malnutrition caseload was climbing to a record high. And in the Western Hemisphere, Haiti had entered hurricane season, for the first time in its history, with no emergency food stocks at all, its safety net gone at the very moment the climate charged storms returned.

These look like separate disasters. They are not. They are symptoms of a single, deliberate convergence: the largest termination of foreign aid ever recorded, colliding with the most punishing climate shocks in a generation. Neither force would be as lethal alone; together they are manufacturing famine, not as an accident but as the predictable result of choices made by Donald Trump and in wealthy capitals. This is how this famine machine was built, and how it can still be dismantled before millions of people die..

The Annihilation

On 30 January 2025, a website went dark.¹ The Famine Early Warning Systems Network, also known as FEWS NET had been created by Ronald Regan and for forty years it did one thing: it told the world where the next famine would arrive before it did. It was built by USAID in 1985, in the long shadow of the Ethiopian famine that killed roughly a million people, after a U.S. president demanded to know why no one had warned him.¹

For four decades it read rainfall, soil moisture, crop yields, livestock prices and conflict across some thirty of the world’s most fragile countries and turned that data into eight-month forecasts accurate enough that aid could be put in place before children starved.When it predicted drought in Ethiopia in 2016, food was moved into place in advance and, in a country that had once buried a generation, almost no one died.¹ Then, in the opening days of 2025, the system that watches for hunger was switched off by Donald Trump.

The chokepoint is a budget line. In a single year, five of the world’s wealthiest Western governments carried out the steepest withdrawal of foreign assistance in the history of the modern aid system, and they did it at the exact moment the climate they had spent two centuries destabilizing with CO2 emissions from fossil fuels was producing its most punishing droughts, floods, and crop failures in a generation. The two shocks did not just happen together. The aid collapse of 2025 reveals something quiet and cruel: how the deliberate removal of a safety net, layered onto the climate emergency which the poorest did nothing to cause, converts chronic poverty into acute famine.

The numbers are not subtle. Official development assistance from the world’s established donors fell 23.1 percent in 2025, to $174.3 billion, that is the largest annual drop ever recorded, dragging global aid back a decade to where it stood in 2015.³ The United States and Donald Trump alone drove three-quarters of the drop, slashing its own assistance by 56.9 percent as it dismantled USAID, terminated roughly 83 percent of its programs, and withdrew from the World Health Organization.³,⁴ For the first time on record, the five largest donors: the United States, Germany, the United Kingdom, Japan, and France, all cut their aid in the same year.³Humanitarian assistance specifically fell 35.8 percent.³ A peer-reviewed forecast in The Lancet estimated that the USAID cuts alone could produce more than 14 million additional deaths by 2030, including 4.5 million children under the age of five.⁴ A later modelling study, accounting for the cascade of European cuts that followed, increased the figure to 9.4 million additional deaths by 2030 and sizeable loss of life thereafter.⁵ And the toll is no longer only a forecast. By early 2026, one year into the dismantling of USAID, independent trackers modelling the cuts attributed more than 760,000 deaths to them already, over half of them children, a number that has gone on climbing through the first half of 2026.

“The rich world did not simply stop helping. It removed the buffer between the climate crisis and the people least able to survive it and then looked away as the two collided.”

The Aid Pipeline and What Happens When It Breaks

Foreign assistance is not charity in the sentimental sense. In dozens of fragile economies, foreign aid is the load-bearing infrastructure, the difference between a bad season and a mass grave. It funds the departments of health, the clinics that treat a malnourished child, the rations that bridge a failed harvest, the water well boreholes that hold off a drought, the surveillance networks that catch a disease outbreak, and the early-warning systems that tell everyone else where to look. Pull that pipeline and you do not merely subtract a service. You remove the shock absorber that stood between these countries and the next climate hazard barreling toward them.

This is where the second crisis enters. Climate change does not act alone in these countries; it acts as a risk multiplier, amplifying every existing weakness in food, water, health, and public finance.⁶ And the multiplier is arriving at an increasing rate with increasing ferocity just as the donor countries make the buffer disappear.

The UNEP Adaptation Gap Report for 2025, aptly titled Running on Empty,^[i] found that developing countries will need between $310 and $365 billion a year to adapt to a warming world by 2035, against the roughly $26 billion in international public adaptation finance actually delivered in 2023: a gap of at least twelvefold, now widening as donor budgets shrink.⁶ The cruelty deepens in conflict zones. The International Rescue Committee found that seventeen of the world’s most conflict-affected, climate-exposed countries saw their development assistance fall by more than 40 percent between 2013 and 2023, even as climate shocks intensified, while capturing only 12 percent of the adaptation finance flowing to the developing world.⁷ Afghanistan and Yemen alone face losses of more than 10 percent of national income from the anticipated aid cuts.⁷

Beneath all of this runs a deeper, slower mechanism: the climate debt trap. When a drought, flood, or storm strikes a poor country, it has to borrow to rebuild, and public debt that averaged 68 percent of GDP in the disaster year climbs to roughly 75 percent within three years.⁸ The interest on that borrowing then crowds out the very services that protect against the next shock. By 2023, forty-eight countries were spending more on external debt service than on the health of their own citizens, up from thirty-five a decade earlier.⁹ Into this doom loop climate damage is feeding debt, debt is starving public services, hollowed-out services invite the next disaster. The wealthy world has now evilly added the further shock of aid withdrawal. Climate hazards depress local credit and erode sovereign fiscal buffers across the Global South;¹⁰ when international assistance is pulled at the same moment, countries are left with empty treasuries and dismantled public services exactly when the physical costs of a warming planet demand unprecedented investment.

The path to hunger is direct, and it runs like this. Aid funds the food rations needed by climate refugees and the projects needed to adapt to climate change. Cut the aid and the rations shrink while the boreholes go unbuilt. A climate shock such as a failed rainy season, a flash flood, a heat-blasted harvest then lands on a community with no buffer left. Crops and livestock die. Food prices spike in local markets. Families cut meals, then cut them again. Children stop growing, then start stunting and then dying. None of this moves at the speed of a headline. It moves at the speed of a growing season. But it moves, reliably, from the cruel spreadsheet in a donor capital to the empty bowl of a child in a displacement camp.

Afghanistan: Total Safety-Net Dissolution

In the most fragile states, the interaction between environmental collapse and aid dependence is at its most deadly and nowhere more than Afghanistan, where the United States had supplied more than 40 percent of humanitarian support before the cuts.¹¹ The country was already caught in chronic, climate-driven water scarcity: severe drought, failed and irregular rains, and flash floods that had been steadily crippling food production and emptying the countryside.¹¹ Onto that, in late 2025, fell two devastating earthquakes and the forced return of millions of Afghans expelled from Iran and Pakistan.¹¹ And then the foreign aid buffer vanished.

When Washington terminated its Afghanistan programs which amounted to more than $560 million slated for 2025, the health system buckled almost overnight.¹¹ The number of closed health facilities surged from 188 in February to over 420 by the end of the year, cutting roughly three million people off from basic health care.¹¹ Nearly 300 nutrition centers shut their doors. The World Food Programme, stripped of U.S. funding, had to collapse its programs from feeding 5.6 million people in the winter of 2024 to barely one million a month in 2025. WFP was forced, in the words of its own officials, to turn away three of every four acutely malnourished children for lack of money.¹¹ For the first time in four years, the number of hungry Afghans rose, to 17.4 million, with seven provinces nearing famine.¹¹ By the first half of 2026 the picture had darkened further: child malnutrition was projected to reach a record 4.9 million, and with its Afghanistan budget collapsing from about $600 million in 2024 toward a projected $200 million, the WFP could reach only around two million of the 17.4 million in acute hunger, still turning away three of every four malnourished children. When the next drought or flood strikes these un-buffered districts, there are no clinics, no early-warning teams, no food stocks, and no nutritional safety net left to turn to. The collapse will be total.

The Horn of Africa and Kenya: Drought Meets the Vanishing Ration

In East Africa, climate change has warped the rhythm of the seasons into something violent and unpredictable, swinging between multi-year droughts and catastrophic, disease-breeding floods. The region is now gripped by yet another failure of the rains. By the close of 2025, FEWS NET, back online but operating at a fraction of its former capacity, estimated that 20 to 25 million people across Somalia, Ethiopia, and Kenya needed humanitarian food assistance, with drought the primary driver for more than half of them.¹² In the pastoral north of Kenya, milk production fell by roughly a third, livestock that survived the 2020–2023 drought began dying again, and staple maize prices in counties such as Kitui ran nearly 20% above their five-year average. By early 2026 the crisis had deepened sharply: after the October–December short rains failed across the region, among the driest such seasons on record, the number in extreme hunger across Kenya, Somalia, and Ethiopia climbed toward 26 million; in Somalia alone the figure facing crisis hunger nearly doubled to 6.5 million, and the IPC projected that close to half of all Somali children under five would need treatment for acute malnutrition by the middle of 2026, even as Somalia’s response plan went barely a tenth funded and Washington withheld support entirely.¹² More than 800,000 Kenyan children were projected to need treatment for acute malnutrition in 2026.¹²

800,000 children needing treatment for acute malnutrition will, even if they survive, carry the consequences of this event for the rest of their lives. These 800,000 children will experience lasting harm: stunted growth and shorter adult height that early nutrition can never fully restore; impaired brain development during the critical first years, translating into lifelong deficits in memory, attention, language, and learning; a heightened lifetime risk of diabetes, high blood pressure, and heart disease as bodies adapted to scarcity later struggle with normal diets; weakened immunity and a months-long window of elevated mortality even after they leave treatment; and lasting damage to their guts and other organs. At the population level, these losses compound into diminished education, lower lifetime earnings, and a cycle that passes from malnourished girls to the low-birthweight children they will one day bear, a quiet, permanent toll that outlasts the famine that caused it. If they experience multiple periods without food, the impacts compound.

These 800,000 children needed emergency treatment for acute malnutrition just at the moment the rations evaporated. As OECD aid contracted at its fastest rate in history, the World Food Programme which had already cut rations for three-quarters of East Africa’s refugees in earlier funding crises was forced into deeper retreat.¹² Kenya hosts hundreds of thousands of refugees in camps such as Kakuma and Dadaab, where populations have been swollen by climate displacement from across the region.¹² When climate shocks spoiled local crops and the simultaneous rollback of food aid forced host families to absorb new survival costs, the result was not only hunger but fracture: as documented in longitudinal studies of refugee-hosting communities, the erosion of support wears down the willingness of host populations to take in the displaced, driving local backlash and regional instability in exactly the zones where there is the greatest need to help.¹³

“Where drought leads, hunger is never far behind. What is new is that the world has now intentionally dismantled the very system built to see the drought coming and provide aid before the famine comes.”

Uganda: The Refugee-Hosting and Drought Nexus

Uganda carries a burden few countries match: it hosts nearly two million refugees, the largest such population in Africa, even as shortening growing seasons and intensifying drought tighten the screws on its own farmers.¹³ The country has long relied on external frameworks to manage that pressure, the agricultural adaptation programs, the sanitation systems, the managed water distribution that allowed displaced populations to survive seasonal shocks rather than be destroyed by them.

Then the funding collapsed. USAID programs in Uganda absorbed a loss on the order of $307 million, a roughly 66 percent programmatic reduction.¹⁴ Academic assessments of frontline settlements such as Nakivale documented what followed: the elimination of USAID-funded agricultural adaptation, sanitation, and water infrastructure left displaced populations entirely exposed to the next climate shock.¹⁴ Without managed water distribution, a localized drought no longer slowed at the edge of the camp, it turned directly into food shortage while public-health infrastructure collapsed.¹⁴ The buffer that converted a hazard into something survivable was simply gone, and the climate hazard arrived anyway and people died.

South Africa: Dismantling the Scientific Frontline

· Not every casualty of the foreign aid withdrawal starves. Some of the damage is to the machinery that keeps hunger and disease from spreading in the first place. As temperatures climb across Southern Africa, the geographic range and transmission windows of vector-borne and infectious disease that impact people, livestock and crops such as tuberculosis, malaria, waterborne outbreaks, Foot-and-Mouth Disease, Tick-Borne Diseases, Lumpy Skin Disease, Maize Lethal Necrosis (MLN) and Vector Transmitted Viruses, Transboundary Plant Pests, are shifting to new countries and to new latitudes, placing new strain on public-health governance exactly as the systems to track them are being dismantled.¹⁵

On 26 February 2025, the United States terminated roughly 90 percent of the USAID-administered PEPFAR projects in South Africa, stripping more than $400 million from a country at the epicenter of the global HIV pandemic.¹⁶ Some 8,000 health workers were fired; clinics across 27 priority districts shed staff or shut entirely.¹⁶ A parallel mandate barred the National Institutes of Health from issuing foreign sub-awards, threatening dozens of research sites and the clinical trials, surveillance networks, and field data collection that the world relies on to understand how a warming climate redraws the maps of diseases.¹⁶,¹⁷ South African institutions stood to lose a substantial share of research income, triggering job cuts that ripple outward through sanitation, food security, and governance programs the same grants once cross-subsidized.¹⁷ The point is not that South Africa will starve.

Nor did the damage stop at human medicine. The same freeze tore through the region’s “One Health” surveillance, the joined-up tracking of human, livestock, and zoonotic disease that is built to catch an outbreak before it can jump the species barrier. Integrated animal-human monitoring programs run with bodies such as the South African Veterinary Association were dismantled, leaving officials blind to pathogens mutating between wildlife and livestock. The defunding of the UN Food and Agriculture Organization, whose emergency veterinary network had drawn roughly 90 percent of its funding from Washington, collapsed the transboundary animal-disease system that had spanned more than fifty countries and shut down the checkpoints that screened livestock in transit, allowing diseases such as foot-and-mouth to cross borders undetected. Broader freezes on agricultural and food-security grants halted field research as well, leaving farmers without the diagnostic pipelines to track the invasive, climate-driven blights now spreading through their crops.¹⁷ The point, again, is not that South Africa will starve. It is that the tools humanity built to watch climate-driven hunger and illness coming, the surveys, the trials, the data needed to track these disasters were switched off at the same time as the early-warning system itself.

Sudan: Famine in the Dark

Sudan is where the two crises meet their most catastrophic expression, and where the result of the blackout is no longer theoretical. Famine has been confirmed in Sudan: first in the Zamzam displacement camp in Darfur, then in Al Fasher and Kadugli, with the risk of famine declared across more than twenty additional areas. In October 2025 the Rapid Support Forces overran Al Fasher after an eighteen-month siege, killing civilians as they fled and driving more than a million people from the city; by February 2026 famine had spread to two further areas of North Darfur, Um Baru and Kernoi, where more than half of small children were acutely malnourished, making Sudan the country with more territory in active famine than anywhere else on earth.¹⁸ Twenty-five million people, half the country’s population, face acute hunger; the World Food Programme reaches an average of 4.2 million a month, including 1.8 million in famine or famine-risk zones, while warning of imminent food and other aid pipelines break.¹⁸

And in Sudan, the early-warning system has gone almost entirely dark. FEWS NET data disappeared in the freeze; the government had already suspended its cooperation with the U.N. classification system; and the NGOs that feed the global hunger-monitoring framework with field surveys have been forced to scale back as their own U.S. funding evaporated.¹,¹⁸ In Sudan, a country sliding into the worst famine of the decade, the world is being asked to respond to a catastrophe it can no longer fully see. As one senior early-warning analyst put it as the system collapsed due to the indifference of the U.S. and other western donors, the global aid and the parallel detection services were pulled at the very moment the risk of multiple simultaneous famines had never been higher.¹

Bangladesh: A Halved Ration in the Cyclone Belt

If Afghanistan shows what total dissolution looks like, Bangladesh shows the same machinery turned on the largest stateless population on earth. Nearly 1.2 million Rohingya, driven out of Myanmar by a campaign the United States itself called a genocide and pushed across the border again by renewed fighting in 2025, are confined to the camps of Cox’s Bazar, barred from working and almost wholly dependent on aid to eat. They are also penned onto one of the most cyclone- and flood-battered coastlines on the planet, where the storms come every year and the camps, stripped of trees and packed onto bare hillsides, dissolve into mud and landslides when they do.

The United States had been the largest single donor to the Rohingya response, supplying more than half of it, roughly $300 million, in 2024. As that money vanished, the World Food Programme cut the monthly food voucher from $12.50 to as little as $6, less than nine cents a meal, and the wider relief effort, only about half funded in 2025, fell to barely 19 percent funded in 2026 which will result in even more drastic cuts to food supplements and more hunger.¹⁹

The pattern is by now familiar: in an earlier round, families lost their shelters to a cyclone only weeks before a funding shortfall forced their rations down. Malnutrition in the camps has climbed to its worst level since the exodus of 2017, with the number of children needing treatment for acute malnutrition rising by more than a 25% in a single year.¹⁹ And as the ration shrinks, the desperate take to the sea, where hundreds of Rohingya drown or vanish each year on smugglers’ boats bound for Malaysia. The buffer between a stateless people and the next storm has been folded up and put away by Donald Trump and other Western donors.

Haiti: No Stocks Left for the Storm

In the Western hemisphere, the same story has a single, stark address. Haiti is the only country in the Americas, and one of just five on earth, where people are enduring catastrophic, famine-like hunger; 5.8 million Haitians, more than half the population, can no longer reliably eat.²⁰ A decade of gang violence, political collapse and economic ruin had already hollowed the country out when, in late 2025, Hurricane Melissa tore into the island.

Here the removal of the buffer is almost literal. For the first time in its operations there, the World Food Programme entered hurricane season with no prepositioned food stocks at all, the funding shortfall having stripped away the contingency reserves it had always kept to feed survivors in a storm’s first days.²⁰ The cupboard was bare at the moment it was most needed. The same shortfalls forced the agency to suspend hot meals for displaced families and to halve the rations of those already at emergency hunger, while Haiti’s 2025 humanitarian plan stood barely 8 percent funded at midyear and a spike in fuel prices, driven by conflict in the Middle East, pushed food still further out of reach.²⁰ The lesson runs north as well: across the Central American Dry Corridor, the drought-cracked belt through Guatemala, Honduras, El Salvador and Nicaragua, failed harvests had by early 2026 left one in six Guatemalans short of food and were driving families toward the United States border, even as the very programs built to keep them fed and rooted were switched off.²⁰

Famine by Subtraction: A War on the Poor

Step back from the individual countries and a single structural reality comes into focus. The hunger now spreading across the Global South is not, in the main, being caused by a sudden absence of food in the world. It is being manufactured by subtraction, the deliberate removal of global aid, in a single budget cycle. Likewise, the deliberate removal of the systems that stood between a warming climate and the people least equipped to endure it. This is famine by subtraction, and it has a chillingly clear arithmetic.

Begin with the rations. The World Food Programme expects that it received 40 percent less funding in 2025 than in 2024, about $6.5 billion against $9.8 billion. This aid reduction held even as global acute food insecurity stayed near its record at 318 million people, 41 million of them at emergency levels.²¹ The agency calculates that its cuts alone could push 13.7 million people from crisis into emergency hunger, a one-third increase, and notes that the number of people in famine or catastrophic hunger has doubled in two years to 1.4 million.²¹ The world Food Programme expects to expects to receive ~$6.4 billion in 2026 compared to the ~$13 billion it needs to reach the 110 million people in desperate need. Across its operations the math is brutally concrete: in South Sudan, every recipient is now on a half-to-two-thirds ration with key foods running out; in the Democratic Republic of the Congo, planned support was slashed from 2.3 million people to 600,000; in Haiti, hot meals stopped and rations were halved.¹⁹ This means millions of people will die and millions of children will suffer from stunting and have life long medical problems because they don’t get enough to eat.

Look more directly at these children. Malnutrition already underlies 45 percent of all deaths globally among children under five, and the main tool against it, the ready-to-use therapeutic food, the peanut paste that pulls a wasting child back from the edge used to run through the exact supply chains that the USAID and other foreign aid cuts broke.²² UNICEF warned that stocks of that therapeutic food were running short in seventeen countries, leaving up to 2.4 million severely malnourished children at risk of going without.²³ In one of the era’s defining images, enough food to feed 3.5 million people for a month, some $98 million worth, including thousands of tonnes of therapeutic paste capable of saving hundreds of thousands of children was left by the Trump Administration to rot in four U.S. government warehouses, some of it destined for incineration or conversion to animal feed, while children starved in Sudan, South Sudan, and beyond.²³

Finally, the aid cuts have subtracted our eyes. The gutting of FEWS NET, which was brought back after its shutdown, but only in a diminished form, and shifted to State Department control, together with the simultaneous strain on the data networks that feed the international hunger-classification system, mean that the cuts have blinded the response as well as bankrupting it.¹ When the Global Report on Food Crises appeared in 2026, its authors warned that the apparent leveling-off of world hunger was partly an artifact of the data: the report rested on the fewest adequately measured countries in a decade, with eighteen left unclassified, among them Ethiopia, where some twenty-seven million people went uncounted meaning hunger most likely had not leveled off. A response that is both poorer and blinder is the structural recipe for the thing the world spent forty years learning to prevent: famine that is seen too late, because it was happening in places where, without aid, and without anyone still watching.

“The food rotted in the warehouse. The clinic closed its doors. The satellite kept watching the drought, but no one was left to read the warning. This is not scarcity. It is an evil decision not to provide international aid - creating hunger and starvation like this around the world is a political choice, it is a war on the poor.”

What Must Change: Policy Changes Proportionate to the Crisis

Donor governments must reverse the humanitarian cuts first, and fast. Humanitarian assistance is the thinnest, most time-sensitive layer of the safety net, these are the ration that prevents a hungry season from becoming a fatal one. Unfortunately, humanitarian aid has absorbed the deepest proportional cut of all.³ Restoring it is not a long-term development question; it is a question of who eats this year and who will starve? The scale is now plain: the World Food Programme says it needs roughly $13 billion in 2026 just to reach 110 million of the hungriest, a third of those in need. Every month humanitarian aid cuts are maintained converts a reversible funding gap into an irreversible death toll that the peer-reviewed literature has already counted in the millions.⁴,⁵

Climate adaptation finance must be protected as the buffer it is and delivered as grants rather than debt. Pouring loans into climate-vulnerable countries only tightens the debt trap that is already crowding health and food spending out of national budgets.⁸,⁹The evidence on prevention is overwhelming: every dollar spent on early risk reduction saves up to fifteen in post-disaster recovery.⁷A world that cannot find $40 billion a year for adaptation will spend many multiples of that on the famines, displacement, and instability that the absence of adaptation funding guarantees.

The early-warning architecture must be rebuilt and shielded from political whim. A famine-monitoring system that can be switched off in a single executive order at the exact moment of maximum risk and maximum need is not a system; it is a liability. FEWS NET and the data pipelines that feed the international classification framework are global public goods, and they should be funded and governed as such because a hunger crisis that no one can see is one that no one can stop.

And the wealthy world must recognize that providing humanitarian aid funding is strategy for global stability, not idle generosity. Food insecurity drives displacement, displacement drives instability, and instability drives the conflicts that close shipping lanes, collapse governments, and ultimately reach the donor nations that imagined themselves insulated. Protecting food aid and adaptation finance is not charity. It is the cheapest insurance policy a stable world has ever been offered, and it is being canceled in real time.

A Warning Without a Warning System

The wealthy nations of the world have told themselves a comforting story about foreign aid: that it was wasteful, that it was optional, that its absence would be absorbed somewhere far away by someone else. That story is being rewritten, season by failing season, by a climate that does not respect national budgets and by the arithmetic of millions of empty food bowls in refugee camps and millions of unnecessary deaths. The aid withdrawal of 2025, which has been mostly maintained since then, adding to the deliberate removal of the global safety net at the precise hour the climate emergency is demanding the increased responses.

The seventeen million Afghans now facing hunger did not dismantle their own health system.¹¹ The families in the drought-cracked Horn of Africa did not vote to halve their rations.¹² The children in Sudan starving in the dark did not switch off the system built to warn the world they were starving.¹⁸ But they are paying for all of it, in skipped meals and stunted growth and the quiet, countable emergency that famine always is. Four decades ago, a famine the world failed to see coming killed a million people and shamed a superpower and President Ronald Regan into building a system so that the world would never be blind to an impending starvation again. In 2025, that system was switched off on purpose. Now the consequences are being written on the faces and bodies of the people and children who are least responsible for climate change or the state of their countries. What is missing this time, is that there is no one in power who cares. We need to care and the world needs to restore humanitarian aid and adaptation resources before more of the world descends into chaos.

“In 1985, the world built a machine to make sure that a massive famine would never happen with no one seeing it coming. In 2025, the wealthiest nation in the history of the Earth lead by Donald Trump, and its allies turned the machine off and then defunded the food and other aid response that the machine existed to trigger in case of a famine disaster. People will die in huge numbers, and these wealthy countries will all bear the shame.”

WFP cut the monthly food voucher from USD 12.50 toward as low as USD 6 (Al Jazeera, 6 Mar 2025; Amnesty International, 17 Mar 2025). Cyclones (e.g. Mocha) and floods repeatedly compound the ration cuts; child acute-malnutrition needs rose ~27% year-on-year, the worst since 2017 (UNICEF; WFP, 7 Mar 2025).

Haiti / Central America: Haiti is the only country in the Americas (one of five globally) with people in catastrophic (IPC 5) hunger; ~5.8 million, over half the population, are acutely food insecure (WFP/IPC, 2025–26). Hurricane Melissa struck southern Haiti in late 2025; for the first time, funding shortfalls left WFP with no prepositioned hurricane-season stocks and forced the suspension of hot meals and the halving of rations; Haiti’s 2025 response plan was ~8% funded at midyear (WFP, 3 Jun 2025 and 15 Oct 2025). A U.S. Food for Peace contribution in April 2026 reached ~390,000 people. On the Central American Dry Corridor (Guatemala, Honduras, El Salvador, Nicaragua), see IPC/UNOCHA (2026): ~3 million Guatemalans (one in six) projected at IPC 3+ in February–April 2026, amid climate-driven crop failure and migration toward the U.S. border.

The drought that has consumed the United States since 2024 is not a weather event waiting to be resolved. It is a regime change that is reshaping the economics of food production, the structure of the cattle industry, and the fiscal viability of hundreds of thousands of family farms. And, as the evidence from Massachusetts to Texas now makes clear, no region of the country is sitting safely outside its perimeter.

Researchers increasingly speak of a “polycrisis” in American agriculture: not one systemic shock but several, arriving simultaneously and amplifying each other until the damage is not additive but multiplicative. The same drought that destroys a wheat field drives up the cost of livestock feed, which forces ranchers to liquidate their breeding herds, which constrains beef supply for years to come, which pushes food prices beyond the reach of families who were already spending nearly a third of their income on groceries. Each crisis knocks out the defenses a farm or a food system would have used against the others.

By mid-June 2026, the pathway from cracked soil to empty grocery shelf has become frighteningly short.

A National Footprint, not a Regional Anomaly

The U.S. Drought Monitor’s June 2026 assessment reveals a national footprint spanning four categories of severity, with exceptional drought, the worst classification entrenched across the Southern Plains and High Plains, including the cow-calf heartland of Nebraska and Texas, now in its sixth consecutive year of sustained dryness. Extreme drought conditions have taken hold across the Western Corn Belt and the Southwest. And moderate to severe drought has spread into the Southeast, parts of the West, and into the Northeast.

U.S. Drought Status - June 2026

Federal U.S. Drought Monitor and state-declared conditions

National Overview (Federal USDM, June 9, 2026)

As of June 9, 2026, the federal U.S. Drought Monitor reported 46.93% of the United States and Puerto Rico, and 56.16% of the Lower 48 states are in drought (Moderate, D1, or worse), affecting roughly 150 million people. Forty-five states were experiencing Moderate Drought or worse. Severe Drought (D2) expanded across the Northeast, Mid-Atlantic, and Minnesota amid widespread heat, while hit-or-miss rainfall improved parts of the Plains and South.

Drought category Approx. share of U.S. area

Abnormally Dry (D0) ~15%

Moderate Drought (D1) 16.4%

Severe Drought (D2) 18.2%

Extreme Drought (D3) 8.8%

Exceptional Drought (D4) 0.9%

Active drought (D1–D4) covered roughly 44% of U.S. area.

National Update (federal USDM, June 18, 2026 — latest weekly release)

The June 18 U.S. Drought Monitor is the most recent weekly map, with data valid through June 16 shows the national picture finally bending, though unevenly. Heavy rain across the Midwest and the central and southern Plains drove widespread improvement, with Tropical Storm Arthur approaching the southeastern Texas coast and promising further relief across the Deep South. Ohio, Indiana, and nearly all of Michigan are now free of drought and abnormal dryness, and even a slice of the exceptional-drought Texas Panhandle was downgraded after two to four inches of rain. As of this update, however, the National Drought Mitigation Center had not yet posted revised June 18 national category percentages, so the June 9 totals above remain the most recent official national breakdown.

The improvement is not universal, and in places the drought is deepening. In northern Minnesota, severe drought pushed north toward the Canadian border, dragging down the headwaters of the Mississippi; north-central Iowa picked up a new patch of moderate drought; and across the High Plains the core of the crisis held firm, with the most severe and exceptional conditions still stretching from eastern Wyoming into western and northern Nebraska and far southern South Dakota, and worsening in eastern Colorado and northwestern Kansas. New England stayed hot and dry, keeping the Northeast under pressure even as the national footprint shrank. The human signal is unmistakable on the ground: on June 15, the town of Liberty in south-central Kentucky declared a state of emergency as the lake that serves as its water supply fell to critical lows, while Florida and southern Georgia continued to report serious water-supply concerns, with Lake Okeechobee still losing more water than it takes in.

The forecast offers cautious relief. NOAA has issued an El Niño Advisory, with the pattern expected to strengthen into the fall, and near-term outlooks favor above-normal rain across much of the Midwest and the Ohio Valley. But the Southwest’s summer monsoon, however wet, is not expected to refill the Colorado or Rio Grande systems, and forecasters warn the south-central Plains could reintensify later in the summer. The national trend line, in other words, is improvement at the margins layered over a drought whose hardest cores which are in the High Plains, the West, and now the Upper Midwest have not yet released their grip.

Dominant drought category by state, U.S. Drought Monitor, May 19, 2026 (most recent complete state-by-state set). “Dominant” = the category covering most of a state’s area; this differs from the June 9 national totals above.

Critically: the damage compounds.

Recent ecological research confirms that drought duration and intensity interact to magnify losses in primary productivity in a non-linear way. Four consecutive years of extreme conditions can cause productivity losses to skyrocket by approximately 2.5-fold compared to the first year. The extended duration into 2026 means agricultural systems are no longer merely stressed. Their baseline resilience is fracturing.

“The drought that began as a weather event has solidified, by June 2026, into a long-duration environmental shock: one that the nation’s crisis-response architecture was not built to handle.”

The Wheat That Wasn’t

There is a number at the center of the 2026 grain crisis that deserves to be repeated until it lands with the weight it carries: 1.525 billion bushels. That is the U.S. total wheat production forecast for 2026. It is the smallest domestic harvest in 54 years. The average production for the last 50 years was 2.1 billion bushels a year, 575 million bushels more than produced in 2026!

In the Southern Plains, Hard Red Winter production has been slashed to 515 million bushels, this is a 36% collapse from 2025 in a single season. In Texas and Oklahoma, nearly 32% of planted acres will not be harvested at all. Crop scouts in northern Kansas reported average yields of 38.3 bushels per acre, against a prior-year average of 50.5. Those missing 12 bushels per acre are the entire profit margin for a family operation, and the baseline global supply that prices wheat from Cairo to Kampala.

The season-average farm price for wheat is now projected at $6.00 per bushel, a forecast USDA actually lowered by 50 cents in June, because bumper harvests in Russia, Turkey, and Ukraine swelled global supply even as the American crop shrank. It is a hard lesson in how a globally traded commodity behaves: a devastated U.S. harvest does not guarantee a price windfall. Higher prices benefit farmers who have a crop to sell, but for the third of producers who will harvest nothing from their winter wheat fields this year, the price is irrelevant either way.

The Cattle That Were Sold

The livestock story is the most structurally consequential chapter of this crisis. When drought destroys rangeland forage, ranchers face an immediate ultimatum: purchase expensive supplemental feed or liquidate their herds. Across the Southern Plains and Southeast, producers have overwhelmingly chosen the latter. The total U.S. cattle inventory has fallen to 86.2 million head — the smallest since 1951. The beef cow herd stands at 27.6 million head, its lowest point since 1961.

The Female Slaughter Ratio tells the story in a single metric. When the proportion of female cattle sent to slaughter rises above 48%, the national herd is in liquidation. In the first quarter of 2026, that ratio climbed to 49.9%. Even at record cattle prices, ranchers in the Southern Plains are unwilling to bet on a heifer whose survival depends on rain that may not come. Tyson Foods has closed its facility in Lexington, Nebraska. Walmart is building independent processing infrastructure. And in June 2026 a new biological threat entered the picture: USDA confirmed New World screwworm — a flesh-eating livestock parasite — in Texas, prompting animal-movement restrictions and quarantines that further squeeze an industry already in retreat. Ground beef is no longer a staple. It is becoming a luxury.

“The drought did not create the fragility. It revealed it. That distinction matters because the same dynamic is now visible from the Plains to the Northeast.”

The Cost That Doesn’t Stop

Urea and nitrogen fertilizer prices surged by 47% in a single month in early 2026. Per-acre production costs have climbed to $890 for corn, $1,336 for rice, and $965 for cotton. Matched against drought-depressed yields, a significant share of American row-crop agriculture is now operating at a net loss.

The American Farm Bureau Federation estimates total net losses across the sector will exceed $50 billionover the three years ending in 2026. The latest agricultural census documented the loss of 140,000 farms between 2017 and 2022, and this is a trend every analyst expects to accelerate.

Lower-income American households were already spending nearly 30% of their total disposable income on food before the worst of 2026’s inflation arrived. Beef prices are projected to rise 6.3% this year. Fresh vegetables, 4.8%. Sugar and processed sweets, 8.1%. The drought that began silently in the topsoil of Oklahoma ends as a direct threat to household food security across every American city.

The El Niño Wildcard

Hanging over every projection in this report is a single shift in the Pacific Ocean. On June 11, NOAA’s Climate Prediction Center issued an El Niño Advisory: the warm phase of the El Niño - Southern Oscillation has formed and is expected to strengthen into the winter of 2026–27, with forecasters putting the odds of a “very strong” event between November and January at roughly 63 percent, strong enough to rank among the most powerful El Nino ever recorded since records began in 1950. After five of the past six winters ran in the opposite, drought-deepening La Niña phase, the arrival of El Niño is the first large-scale climate signal in years that could work in American agriculture’s favor. But “could” is the operative word.

The textbook El Niño nudges the Pacific jet stream south, steering wetter, cooler weather across the southern tier of the country from late fall into spring, precisely the Southern Plains and Southwest where this drought has been entrenched for the longest time. Past El Niño winters, among them 1957–58, 1982–83, 1997–98, and 2015–16, acted as outright drought-busters there. Yet NOAA is explicit that the pattern guarantees nothing: the 2023-24 event fizzled across the South, and the agency’s new Relative Oceanic Niño Index, adopted in February 2026 to account for warming oceans, has tended to dampen the apparent strength of these events. Even a textbook outcome carries a sting in the tail, because the same southward storm track typically leaves the Ohio and Tennessee valleys, the Northern Rockies, and the Pacific Northwest drier than normal, and the winter rain that greens up western rangeland can simply become wildfire fuel once summer heat returns. For Massachusetts and the wider Northeast, the El Niño signal is weak and mixed, offering little assurance of relief.

For food production the calculus is genuinely double-edged. A wetter second half of the growing season would favor the corn and soybean belt, consistent with the historical pattern in which U.S. soybean yields improve by roughly 2 to 5 percent in El Niño years, and a wet Southern Plains winter could finally let drought-stricken winter wheat re-establish for the 2027 harvest. But none of that reaches this year’s devastated crop, and the relief, if it comes, arrives on a lag: the production impact of an ENSO event typically peaks six to twelve months after the ocean signal does, pushing the real consequences, for better and for worse, into 2027 and 2028.

The larger risk is global, and it runs straight back to the American grocery shelf. A strong El Niño tends to parch exactly the regions the United States leans on to backfill a short domestic harvest: it weakens the Indian and Southeast Asian monsoons that govern rice, dries the West African and Indonesian belts that dominate cocoa and palm oil, and historically cuts Australian wheat exports. The Food and Agriculture Organization has already issued a joint anticipatory-action appeal with the World Food Programme covering the 2026–27 El Niño window, and analysts warn the event is landing atop a fertilizer market still disrupted by conflict in the Middle East. Because El Niño’s effect on global temperature is usually strongest in its second year, the heaviest pressure on world food prices, and on the imported staples that buffer American supply, is likely to build through 2027. The same pattern that may rescue the wheat fields of Oklahoma could, in the very same stroke, raise the price of the rice, sugar, and cooking oil sitting beside the flour on the shelf.

“El Niño is the first climate signal in years that could ease America’s drought. But a pattern that waters the Southern Plains while drying the rice paddies of Asia does not so much end the food crisis as redistribute it.”

The Warning in the Soil

The Southern Plains have been in drought stress for six consecutive years. The High Plains Aquifer is not recovering on any human timescale. The cattle herd will not rebuild before 2028 at the earliest.

The path from cracked soil to empty shelf is shorter than it has ever been. The encouraging news is that the same connections that make it dangerous also make it solvable, but only if policymakers are willing to treat this not as a series of isolated seasonal disasters but as the deeply connected, compounding crisis the science now tells us it has become.

For Massachusetts and for the nation, the warning is already in the soil. The question is whether we are listening and whether we are pushing our politicians to act.

Notes & Caveats

• “Dominant” category is the level covering most of a state’s area; a state can hold more-severe pockets (e.g., D3/D4) not reflected by its dominant class. No state was dominantly D4.

• The federal USDM (D0–D4) is updated weekly and mapped at sub-county detail; state systems use their own indices and update monthly or on demand, so levels and dates can differ.

• Dates are mixed by design: state-by-state dominant categories reflect May 19, 2026 (the most recent complete state-by-state set); the official national category totals reflect the June 9, 2026 U.S. Drought Monitor, which remained the most recent national breakdown posted by the National Drought Mitigation Center as of this update; the qualitative national update reflects the June 18, 2026 U.S. Drought Monitor (data valid June 16), the latest weekly release; Massachusetts reflects the state’s June 9, 2026 declaration; and crop and livestock figures reflect USDA’s June 11, 2026 WASDE and the January 30, 2026 Cattle report. This update is current as of June 21, 2026.

• Massachusetts’ drought regions are defined by groups of towns; county shading maps those regions onto counties as a close approximation (Norfolk spans the Northeast and Southeast regions).

The 2026 winter wheat crop that failed around the world.

The Hungriest Year This Century

In 2025, for the first time in the twenty-first century, famine was confirmed in two countries at the same time: the Gaza Strip and parts of Sudan.¹ Famine is the most extreme classification on the international scale of hunger, reached only when starvation, destitution, and death have already begun. That two of them arrived in the same year was described by the United Nations Secretary-General as an unprecedented development.² It was also a symptom of something larger.

By the start of 2026, an estimated 318 million people faced acute hunger, roughly double the level recorded before the COVID-19 pandemic, with some 41 million of them at emergency levels of food insecurity or worse.³ In the most recent global accounting, more than 266 million people across 47 countries were in crisis or beyond, nearly a quarter of every population that analysts were able to measure.⁴ The number of people at the very edge, at emergency-levels of hunger, has nearly tripled since 2016.⁵ More than 85 million people have been driven from their homes inside these food-crisis countries, and the displaced are consistently hungrier than the communities that host them.⁶

Ask the humanitarian officials who track this catastrophe what is causing it, and the answer compresses, almost universally, into three words: conflict, climate change, and economic shocks.⁷ Call them the three C’s: conflict, climate, and cost. They are not three separate emergencies that happen to be occurring at once. They are three strands of the same rope, each pulling the others tighter. A drought raises the price of bread; the price of bread brings people into the streets; the unrest becomes a war; the war burns the next harvest. Hunger is rarely the product of one cause. It is the product of the three C’s braiding together.

Hunger on this scale is not a natural disaster. It is a man-made one, assembled from three forces we understand, can measure, and could choose to confront.

But we are not.

The Many Faces of Hunger

Before tracing the forces behind this emergency, it helps to be precise about what the word hunger means, because it covers several very different things. The 318 million people in acute crisis³ are the part of the problem that reaches the headlines, but they sit at the sharp end of a much larger structure. Hunger is best understood as a set of nested measures — each broader category containing the narrower, more severe one — all within the wider umbrella of malnutrition. The figures for 2024, drawn from the UN’s annual State of Food Security and Nutrition in the World, describe that structure.⁸

Nutrition in the World, describe that structure.⁸

Cannot afford a healthy diet - 2.6 billion people nearly 1 in 3 people on Earth don’t have enough to eat

Moderate or severe food insecurity - 2.3 billion people don’t know where their next meal is coming from and ran out of food, skipped meals, or cut the quality and quantity of food for lack of money or access.

Chronic hunger (undernourishment) 673 million people (8.2%)

Habitually insufficient dietary energy, sustained over roughly a year; modeled at the population level.

Acute hunger (food crisis, IPC/CH Phase 3+) 318 million people.

Shock-driven food emergencies severe enough to threaten lives and livelihoods now — the focus of this article.

Famine / starvation (IPC Phase 5) ~1.4 million people.

Catastrophe: starvation, destitution, and death already under way. A separate, acute scale.

Hidden hunger cross-cutting. Micronutrient deficiency (iron, iodine, vitamin A, zinc); can coexist with adequate calories and even with overweight.

All major grains are storing fewer important nutrients due to climate change. The measures deepen with severity and are roughly nested within malnutrition in all forms; hidden hunger cuts across every tier, and into the well-fed. The nesting is only approximate, because each measure uses a different method, calorie modeling, experience surveys, and diet-cost calculations, so a person can fall into one category without another. in the World, describe that structure.⁸

These broader categories describe hunger as a standing condition: chronic, structural, and shaped over years by poverty, farm productivity, and the price of food. The crisis at the center of this article is something narrower and sharper. Acute hunger, and its catastrophic extreme, famine, are measured on a separate, shock-driven scale, and they are largely what the three C’s produce. Climate, conflict, and cost are the forces that tip people out of the broad structural categories and into emergency, turning chronic vulnerability into acute crisis and, at the extreme, into the starvation the famine classification records.⁹ Seen this way, the 2.6 billion who cannot afford a healthy diet are the reservoir; the 318 million in acute crisis are those the three C’s have pushed over the edge; and the roughly 1.4 million at famine’s core are those for whom the fall has already turned fatal.

Famine is not a different disease from everyday hunger. It is the same condition at its end stage, it is what happens when the three C’s finish what poverty began.

The First C: Climate

Climate may be the fastest-growing driver of all. Since 2018, the number of people whose hunger is driven primarily by weather extremes has tripled, from about 29 million to roughly 96 million.¹⁰ Drought is now the leading single cause of agricultural production loss on the planet, and the warming that is making droughts longer and deeper is making floods, cyclones, and erratic rainfall more frequent at the same time.¹¹ The seasons that farmers have read for generations are becoming unreliable, and a missed planting window cannot be reopened.

The effect is already visible. In Afghanistan, repeated drought and flooding have destroyed crops and pushed farming families off their land and onto aid.¹² In Syria, crop production has fallen by more than half.¹³ A single hurricane tore through Jamaica, Haiti, and Cuba and erased harvests in a matter of hours.¹³ And the trajectory points down: climate models project that, compared with a world without warming, climate change could push somewhere between 1 million and 183 million additional people into the ranks of those at risk of hunger, in part by driving cereal prices upward across the coming decades.¹⁴

The transmission works the way every climate-to-hunger transmission works. A flood or a drought cuts the harvest. A smaller harvest means tighter supply. Tighter supply means higher prices. Higher prices price the poorest out of the market, and the poorest are concentrated precisely in the regions where the climate is turning most hostile.¹⁵ The global rate of undernourishment has inched downward in recent years, but the gains are wildly uneven, and much of sub-Saharan Africa has been left behind by them entirely.¹⁶

The atmosphere does not check a passport. But the hunger that a changing climate produces falls almost entirely on

the people who did the least to change it.

The Second C: Conflict

If climate is the fastest-growing driver, conflict is the largest, and it is not close. It is the primary cause of food insecurity in 14 of the 16 hunger hotspots that the Food and Agriculture Organization and the World Food Programme are watching most closely, and it sits behind roughly two-thirds of all acute hunger.¹⁷ The six places of highest concern including the Sudan, the Gaza Strip, South Sudan, Yemen, Mali, and Haiti, are, with one exception, defined by violence.¹⁸ Since 2018, the number of people whose hunger is driven primarily by conflict has nearly doubled, from about 74 million to roughly 140 million.¹⁹

The mechanism is brutally direct. War empties fields and kills the people who would have planted them. It severs roads and markets. It displaces farmers into camps where they consume food rather than grow it. And, increasingly, it is waged deliberately against the food system itself when combatants block convoys, besiege cities, and starve populations as a method of war. Nigeria, the Democratic Republic of the Congo, and Sudan alone accounted for tens of millions of acutely food-insecure people in 2025, the wreckage of overlapping insurgencies and civil wars.²⁰ Gaza has been in famine since the summer of 2025; Sudan’s famine was first confirmed in August 2024 and has only spread.²¹

And What Causes the Conflict

Here the arrow turns around. Conflict produces hunger, but hunger also produces conflict, and the two trap each other in a loop. Researchers reviewing more than a hundred studies for the World Food Programme concluded that food insecurity is a “threat multiplier” for violent conflict: when people cannot eat, especially when a sudden spike in food prices is to blame, the risk of riots, civil conflict, and the breakdown of governments rises sharply.²² A separate review of sixty peer-reviewed studies traced a dozen distinct drivers of food insecurity to eight different forms of instability, from protests and riots to outright civil war.²³

What converts hunger into violence is rarely hunger alone. It is hunger layered on top of grievance: economic desperation, an inflamed pre-existing wound, inequality between different tribes or races of people, a collapse of trust in a government that cannot or will not feed its people.²³ Young people excluded from work and from a political voice are the most combustible fuel of all.²⁴ The pattern is old. The bread riots that helped ignite the French Revolution in 1789 ran on the price of flour; the global food-price spikes of 2007–2008 set off unrest across dozens of countries; in the Syrian war, the price of staples in some places multiplied many times over as production collapsed and transport costs soared.²⁵ Food insecurity does not light every fire. But it dries the kindling, and a sudden jump in the price of a loaf of bread can be the spark.

Hunger and war are not two problems. They are one problem wearing two faces, and each face feeds the other.

When the Drought Comes First

There is a second arrow, and it runs straight from the first C into this one. Climate does not only starve people; it sets them against each other. Security analysts have a name for it, climate is a “threat multiplier,” and the mechanism is depressingly simple. When drought shrinks the water, the grazing land, and the arable soil, groups that once shared those resources begin to compete for them, and competition among the desperate has a way of curdling into violence.²⁶Syria is the case most often cited. From 2006 to 2010 the country endured the worst drought in its instrumental record, one that climate scientists estimate human warming made two to three times more likely, which collapsed harvests and drove perhaps a million and a half rural Syrians into the cities, where the newcomers met unemployment, overstretched services, and a government indifferent to their plight. Researchers are careful not to call the drought the cause of the war that erupted in 2011, but many regard it as a contributing accelerant that helped load the conditions for revolt.²⁷

It is not an isolated case. Darfur is often called the world’s first climate-change conflict: as the Sahara crept south by roughly a mile a year and rainfall fell by 15 to 30 percent, Arab herders and African farmers were forced into the same shrinking commons, and a quarrel over water and pasture hardened, and it happened under a government willing to weaponize it into genocide.²⁸ Around Lake Chad, which has lost the great majority of its surface area, vanishing water has pushed herders, farmers, and fishers into open conflict and handed extremist groups such as Boko Haram a steady supply of dispossessed recruits.²⁹ Similar fault lines run through the wider Sahel, the Horn of Africa, and South Sudan. The honest reading of this evidence is not that a warming climate reliably produces war, but governance, ethnicity, and inequality always do the deciding. It is that climate change loads the gun those other forces fire, and a hungry, displaced, resource-starved population is exactly the tinder that turns a local dispute into a civil war, and a civil war back into famine.

Climate change rarely fires the first shot. It loads the chamber and turns drought into scarcity, scarcity into grievance, and grievance into war.

The Third C: Cost

The third C is the quietest and, in proportional terms, the most explosive. Since 2018, the number of people whose hunger is driven primarily by economic shocks has risen sixfold, from about 10 million to roughly 59 million.³⁰ This is the hunger of people who live where the bombs are not falling and the rain is still coming, but who simply cannot afford to eat. It is a crisis of price and of debt, not of supply.

The numbers are staggering at the household level. Food-price inflation in Haiti reached 34 percent in a single month of 2025; in Sudan it ran above 60 percent; Nigeria has endured ten consecutive years of double-digit inflation.³¹ Behind those figures sits a weak global economy growing at around 3 percent, developing nations buckling under unsustainable debt, currencies losing value, and governments imposing austerity that strips away the very purchasing power households need to buy food.³¹ In Haiti where more than five million people are now acutely food-insecure, the principal driver is not a battlefield or a drought. It is economic collapse and the price of a meal.³²

This is the C that most directly reaches the grocery aisle in wealthy countries too, because food is traded on global markets and prices set in one place ripple to another. But its sharpest edge is in the poorest economies, where families already spend the largest share of their income on food and have the least room to absorb a single bad month. For them, every percentage point of food inflation is not an inconvenience. It is a meal removed from the table.

In the poorest households on earth, hunger is not always a question of whether the food exists. It is a question of whether the family can afford it.

When the Three C’s Converge

The reason the three C’s are so dangerous is that they almost never arrive alone. They compound. The chain runs like this. A changing climate cuts the harvest. The smaller harvest drives prices up. Higher prices deepen the economic squeeze on families who were already stretched. Economic desperation hardens into grievance, especially where people have lost faith in their government. Grievance, in the wrong conditions, becomes conflict. And conflict destroys the next harvest, blocks the roads, and turns away the aid — which makes the hunger worse, which feeds the next round of grievance. Each C is an accelerant for the others, and the loop, once it is turning, is very hard to stop.

This is why the worst-hit places are almost always suffering from all three at once. Sudan is a war, but it is also an economy in freefall, with inflation above 60 percent. Afghanistan is a climate catastrophe of drought and flood, but it is also an economy hollowed out by isolation and the forced return of more than a million and a half people with nothing.¹²Haiti is an economic implosion, but it is also gang violence and displacement. The three C’s do not take turns. They stack.

The Fourth Failure: A Safety Net Pulled Away

There is a force that can interrupt this loop, and the world has spent decades building it: humanitarian food assistance. At the precise moment the three C’s are intensifying, that buffer is being dismantled. The Trump Administration gutted USAID in a single day which by some estimates will cause up to 25 million deaths. By late 2025, barely a quarter of the global appeal for humanitarian funding was financed, Approximately, $11.5 billion dollars of the needed $45 billion was given by the wealthy countries of the world. This is the largest shortfall ever recorded.³³ Humanitarian funding has fallen back to levels last seen a decade ago, and agencies have been forced to cut food from the hungry to keep the starving alive.³⁴

The largest single cause of the collapse is the retreat of the United States, traditionally the world’s biggest food-aid donor. After the dismantling USAID and congressionally approved cuts, U.S. contributions to the World Food Programme fell from roughly 4.5 billion dollars to about 1.5 billion in a single year.³⁵ The consequences are immediate and arithmetic. In Kenya, rations for hundreds of thousands of refugees fell to barely a quarter of a standard portion; in Uganda, monthly support per refugee was cut from 16 dollars to 5; in northeastern Nigeria, an operation that reached 1.3 million people during the 2025 lean season was projected to reach just 72,000.³⁶ These are not market forces. They are decisions, made in capitals far from the camps to let the poor die.

A harvest can fail because of the weather. A food ration fails only because someone decided to stop paying for it.

What Must Change: Treating the Three C’s as One System

The first imperative is to stop the bleeding. Humanitarian food funding must be restored and protected, because the alternative is widespread irreversible childhood stunting and preventable death. The economics here are not even close: anticipatory action meaning getting assistance to people before a crisis fully lands is far cheaper than emergency response after the fact, and resilience investments such as land restoration in the Sahel have been shown to return as much as 30 dollars for every dollar spent.³⁷ Cutting food aid during a compounding crisis is not fiscal discipline. It is the transfer of a manufactured risk onto the people least able to bear it.

The deeper imperative is to stop treating the three C’s as three separate problems. Climate adaptation, conflict prevention, and social protection are routinely funded, staffed, and argued over in different rooms, yet on the ground they are a single, interlocking system. Social protection is the clearest example: a reliable safety net does not only feed people through a sudden shock; it rebuilds the trust in government that makes a person less likely to choose conflict over peace when the food runs short.²⁴ Investing in resilience is, simultaneously, climate policy, anti-hunger policy, and conflict-prevention policy. The silos are an administrative convenience. The crises do not respect them.

And the framing must change. Food security has been shown, repeatedly, to underwrite political stability, and instability is what closes borders, severs supply chains, and pulls great powers into regional wars.³⁸ Protecting the world’s ability to feed its poorest is not charity. It is a strategic necessity. It is the cheapest insurance policy against the conflicts the wealthy world will otherwise pay for many times over.

The Arithmetic of a Warning

Three hundred and eighteen million people. Two simultaneous famines. A hunger crisis that has doubled in the space of a few years. These are not the statistics of an unlucky season. They are the readout of three forces, climate, conflict, and cost that we can name, that we can measure, and that, unlike a meteor or a plague, are very largely of human making.

The families in Sudan and Gaza living through confirmed famine did not warm the planet. The smallholder in Afghanistan watching a third failed harvest did not start the war next door. The mother in Haiti who cannot afford a sack of rice did not design the debt that hollowed out her currency. They did not cause the three C’s. They are simply the ones paying for it in skipped meals, in stunted children with life-long health problems, in the quiet, grinding emergency that hunger always is.

That the crisis is man-made is the bleak part. It is also the hopeful part, because what was assembled by choices can be disassembled by them. The climate can be adapted to and slowed. The conflicts can be prevented, mediated, and starved of the grievances that feed them. The economic shocks can be cushioned by the safety net we have already built and are now, inexplicably, taking apart. The three C’s have delivered their warning, in the plainest arithmetic there is. Whether to heed it belongs, as it always does, to those with wealthy nations and people who have the resources to act. It also depends on whether they understand that profound hunger, left to compound, has a way of arriving eventually at every door. Even the 1% are not safe from the crises they are creating.

The three C’s are man-made. That is the tragedy. It is also the only reason for hope.

The 2006–2010 drought was the worst in the instrumental record; the authors estimate anthropogenic warming made a drought of that severity 2–3 times more likely, and link crop failure and the rural-to-urban migration of roughly 1.5 million people to conditions preceding the 2011 uprising. The thesis is contested — see Selby, J. et al.

Extreme heat is now the deadliest form of weather in the United States. It kills more Americans every year than floods, tornadoes, and hurricanes combined. Climate induced extreme heat is destroying crops, straining the bodies of outdoor workers, triggering psychiatric emergencies, and driving food insecurity deeper into communities that had no cushion left to absorb another blow. And the people bearing the greatest weight of this crisis are low-income families, Black and Latino households, agricultural workers, the elderly, the disabled and veterans are the people who contributed the least to creating climate change, but who are suffering the most.

This is not a future problem. It is the present emergency hiding in plain sight and being totally ignored by the federal government!

🌡️ Not Just Hotter — Fundamentally Different

The first thing to understand about the new heat is that it has changed in character, not just in degree.

Heatwaves are no longer releasing their grip at night.

High-pressure heat domes now trap hot air for days or weeks at a stretch, eliminating the overnight cooling that allows the human body and the existing infrastructure keeping us alive to recover. When temperatures stay above 90°F at 2 a.m., the cumulative physiological toll is categorically different from a hot afternoon followed by a cool night. with these new heatwaves, the body never catches up.

They are arriving earlier.

Record-shattering temperatures hit Western North America in March 2026, catching populations, agricultural cycles, and public health systems unprepared before anyone had a chance to acclimatize. The heat season is no longer summer, it is most of the year.

Heatwaves are compounding the other symptoms of climate change.

Extreme heat arrives alongside stagnant air and drought, degrading air quality and drying out water reserves simultaneously. It does not arrive in isolation. It arrives on top of the flood that preceded it, the wildfire smoke still in the air, and the farm already stressed by years of moisture deficit.

The numbers tell the story of an acceleration that should alarm everyone. In cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to ten per year between 2010 and 2020. Record highs now occur twice as often as record lows across the continental US. The last 11 years have been the hottest 11 years ever recorded! Think about that for a second. Scientists have documented that there is a clear acceleration in warming beyond anything the previous 50-year trend would predict. The summer of 2025 was likely the coolest summer many Americans alive today will ever experience again.

“American families are being asked to absorb a climate shock they did not create, on bodies that were never designed for this heat, without the infrastructure or the safety nets that a crisis of this scale demands.”

🏥 What Extreme Heat Does to the Human Body

Extreme heat is the leading cause of weather-related death in the United States and the gap between heat fatalities and deaths caused by the next-closest weather category is not small, it is enormous.

The direct toll is staggering.

More than 21,000 deaths in the United States from 1999 to 2023 were heat-related, with mortality rates beginning to rise most sharply from 2016 onward. Between 2000 and 2025, heat deaths increased by more than 50% above historic baselines. In 2023 alone, high temperatures caused 28,000 additional injuries. By the 2090s, projections put cumulative additional deaths from extreme heat in major US urban areas at roughly 28,000 per year that means a 9/11 catastrophe every four months, every year, caused by the weather. The terrorists behind these deaths are the fossil fuel companies, their banks and the politicians who they have bought off and convinced not to take action on climate change.

Physiology is unforgiving.

Heat stress occurs when the body cannot cool itself effectively through sweating. When humidity is high, sweat evaporates more slowly, or not at all, pushing the body toward heat exhaustion and heat stroke. When extreme heat persists through the night, the cumulative stress builds without relief. For people without air conditioning, without the ability to leave work, without the means to pay a utility bill that has doubled, that cumulative stress actually kills.

Heat induced illnesses are not just a summer heart attack.

Research published in 2026 has increasingly identified chronic recurrent heat exposure as a driver of kidney disease, even in previously healthy outdoor workers. High heat and heatwaves exacerbate cardiovascular disease, respiratory conditions, and diabetes. For people already living with high blood pressure, COPD, or chronic illness, who are mostly people concentrated in lower-income communities, heatwaves don’t create new medical emergencies so much as accelerate existing ones catastrophically into hospitalizations and deaths.

Heat waves degrade the air.

Extreme heat traps pollutants, raising concentrations of ozone and fine particulate matter across urban areas. The same weather event that overheats the body also poisons the air being breathed by the children, the elderly, and the people with asthma or heart conditions who can least afford another physiological insult.

The mental health toll is real and undercounted.

Sustained extreme heat is linked to increases in anxiety and psychiatric emergencies. These psychiatric conditions are exacerbated by the stress of financial pressure from soaring utility bills, the displacement and disruption of extreme weather events, and the breakdown of social networks during prolonged crises. A 2026 study of Boston specifically found that citywide heat interventions measurably changed rates of psychiatric emergency services use. The connection between rising temperatures and mental health distress is not speculative. It is documented, and it is getting worse with every successive year of hotter conditions.

🎯 The Inequality Hidden Inside Every Heatwave

The heat does not fall equally. It never has.

Nearly 210 million Americans live in counties vulnerable to health threats from unexpectedly high summer temperatures. But within that vast exposure, vulnerability is not distributed by chance. It is distributed by race, income, housing, and the presence or absence of tree canopy. The urban heat island effect that makes a block in Chelsea, Massachusetts, feel like a desert while a leafy suburb three miles away stays ten degrees cooler is real and it is a result of the growing inequality in America.

Black, Latino, and Indigenous households experience heat-related illness and death at rates that reflect generations of disinvestment in the neighborhoods they were redlined into. The 1995 Chicago Heatwave, which killed over 700 people, acts as a case study that should have long ago transformed policy. In the fifteen community areas with the highest death rates, ten had populations that were 94–99% African American. Social isolation, poverty, and the absence of air conditioning were as much a cause of death as temperature. Thirty years later, the same structural vulnerabilities remain. Only the temperatures are higher and the length of heatwaves and their severity have also grown worse.

Projections now show that the largest increases in heat-related death over the coming decades will fall on older, Black, and Hispanic populations. These are not projections about people in far-off places. They are projections about Americans in American cities these deaths will happen in Phoenix, in Houston, in Miami, in the communities of the Mississippi Delta and the Southern Plains. Are we going to do anything to prevent them?

“The heat does not care whether you caused it. It finds the people who can least afford to survive it and it stays there longest.”

Outdoor workers, including the agricultural laborers, construction workers, and delivery drivers who keep the country fed and functioning face the threat at its most direct. Triple-digit temperatures are arriving earlier and more frequently, and for workers who cannot choose to go inside, that is not an inconvenience. It is an occupational death risk. In 2023 alone, high temperatures caused 28,000 additional workplace injuries across the United States.

🌾 From the Body to the Table: Heat, Crops, and the Coming Food Price Wave

The connection between extreme heat and hunger runs through two channels at once. One is the direct physiological channel: bodies stressed by heat need more nutrition to recover, while the mental health burden of heat reduces the capacity to manage household food security. The other is the agricultural and economic channel: heat destroys crops, disrupts supply chains, and drives food prices higher in ways that fall hardest on households with the least ability to afford these price increases.

Heat is devastating American agriculture.

Most major staple crops, from corn, to wheat, and soybeans, experience significant yield declines when temperatures exceed 86°F. Extreme heat disrupts pollination, weakens plant structures, and can cause total crop failure during critical growth stages. A major heatwave across North America in 2021 led to significant fruit crop losses. Heat and drought in the Southwest have become near-permanent features of the agricultural calendar. The Southern Plains, now in its sixth consecutive year of drought, where more than 95% of the region was experiencing some level of drought or abnormal dryness at the start of the 2026 planting season, with Texas, Oklahoma, and Colorado reaching nearly 100%, is both the breadbasket of America and the front line in the fight to maintain America’s status as one of the breadbaskets of the world.

Livestock are not spared.

Pigs and poultry suffer heat stress that reduces growth, lowers productivity, and in severe cases causes mass die-offs. Marine heatwaves reduce oxygen levels in coastal waters, putting intense pressure on fisheries and aquaculture that millions of Americans depend on for affordable protein. The avian influenza crisis that killed more than 120 million laying hens between 2022 and early 2025 was worsened by the heat conditions that stress commercial flocks and compromise biosecurity.

The cold chain breaks in the heat.

A significant portion of food loss occurs after harvest, when inadequate refrigeration infrastructure meets a spike in demand during extreme heat events, which occurs precisely when the power grid is already strained. Spoilage rises. Food waste rises. Effective food production falls. And the price of what remains on the shelf goes up and more people become food insecure.

The price transmission is reliable and cruel.

Higher production costs, tighter supply, and logistics failures translate into higher retail food prices. They do so with a lag of one to two growing seasons. The delayed impact is slow enough that the connection goes unnoticed in political debate, fast enough that it hits the grocery bill within a year. American consumers were already paying 6.8% annual grocery inflation for the twelve months to June 2025. The compounding effects of climate-driven heat are a primary driver of that number and the continuing increase in food prices does not look like it’s going to stop.

For families in the bottom income 20% of the economic spectrum who already spend nearly a third of their entire budget on food, every percentage point of food price inflation driven by a climate crisis they played no part in creating is a meal skipped, a bill unpaid, a child going to school hungry.

🍽️ The Hunger That Hides in the Heatwave

The United States entered 2026 with 47.4 million people, 13.5% of the population, already living in food-insecure households, a sharp increase from the decade-low of 10.2% recorded in 2021. Feeding America’s nationwide network was already reporting record demand at food pantries in Houston, Phoenix, Atlanta, and Chicago through 2025. More than one in eight people in the wealthiest nation in human history does not know where their next meal is coming from. Climate-driven heat is arriving into a food security landscape already at crisis levels.

Here in Massachusetts, the numbers are stark. A record 40% of Massachusetts households, approximately 1.1 million people, experienced food insecurity in 2025, according to The Greater Boston Food Bank and Mass General Brigham. That rate has more than doubled since 2019. In Hampden County, it exceeded 50%. Hispanic households reached 63%. These numbers reflect the compounding effects of rising costs, inadequate wages, and a fraying of the public safety net; but they also reflect what heat does to household economics: higher utility bills, more sick days, lost wages for outdoor workers, and the rising cost of the food itself.

The health cost of that hunger loops back, viciously. In 2025, food insecurity was associated with $1.6 billion in emergency room visits and hospitalizations among adult MassHealth members in Massachusetts alone with estimated excess hospitalization costs of up to $13,257 per food-insecure adult. Hunger makes people sicker. Sickness drives people deeper into poverty. Poverty makes the heat more dangerous. The spiral is self-reinforcing and accelerating.

The buffer between a heat-driven food crisis and Massachusetts hunger is SNAP and it is being cut at exactly the wrong moment.

Under the One Big Beautiful Bill Act of 2025, future benefit increases linked to the Thrifty Food Plan are now capped, limiting how much support can keep pace with rising food prices. Nearly 4.3 million Americans were removed from the program between January 2025 and January 2026. In Massachusetts alone, more than 150,000 residents are seeing reduced or cancelled benefits. At the same time, food supplied to the Greater Boston Food Bank through the USDA has been reduced by nearly 36% since October 2025. One food pantry that served 6,510 individuals in 2020 served 32,780 in 2025. That is five times the demand in five years!

“The food bank queue is growing. The farm income is deteriorating. The temperature records keep falling. All of these are consequences of the same failure: a society that built its food system, its housing stock, and its public health infrastructure for a climate that no longer exists.”

🔧 What a Proportionate Response Looks Like

Protect and expand nutrition assistance now.

Cutting SNAP during a period of climate-driven food price inflation is not fiscal discipline. It is a transfer of the costs of this crisis onto the families with the least capacity to survive it. The federal government must reverse course. States like Massachusetts are trying to fill the gap. Governor Healey has proposed $55 million for the state’s Emergency Food Assistance Program for fiscal year 2027, but state budgets cannot substitute for federal commitment at the scale this crisis demands.

Build heat resilience into every neighborhood, not just wealthy ones.

Massachusetts’ ResilientMass Plan, Boston’s Project Shade, and the city’s exploration of a harbor-based thermal energy network are genuine steps in the right direction. Cooling centers, expanded tree canopy, and heat-resilient housing design are not amenities. They are public health infrastructure. The fact that Chelsea residents swelter in an urban heat island while nearby suburbs stay cool is a policy failure, not a natural condition.

Invest in climate-resilient agriculture.

Research demonstrates that integrated soil-crop management systems can reduce synthetic nitrogen fertilizer requirements by 30–50% while maintaining yields. Heat-tolerant crop varieties, diversified rotations, and conservation practices are national security investments as much as they are agricultural ones. Every season of delayed investment is another season of compounding exposure.

Restore food aid funding internationally.

The United States contributed approximately roughly 40% of the World Food Programme’s budget for fiscal year 2024. By 2025, US humanitarian aid had collapsed from roughly $14 billion to $3.7 billion. Research consistently shows that food insecurity drives political instability, and political instability creates the conditions for the regional conflicts and supply chain disruptions that make domestic food security worse. Climate change makes all of these conditions worse creating a global tinderbox. Protecting food aid is not charity. It is a strategic investment in world peace.

⚠️ A Warning in the Temperature Record

The United States has long told itself a story about its resilience, about an abundance so vast and a technology so advanced that the worst effects of climate change would arrive somewhere else first or could be innovated around before the impacts of climate change became an emergency.

That story is over. It is over in the 40% of Massachusetts households that cannot reliably feed themselves. It is over in the 28,000 heat-related injuries recorded last year. It is over in the farm income projections that keep darkening and the crop production that is dropping year by year. It is over in the psychiatric emergency rooms of Boston. It is over on the faces of the farmworkers in the Central Valley and the Southern Plains who have no option to go inside.

The 47.4 million Americans already food-insecure before the heat season of 2025 did not cause the climate crisis. The outdoor workers dying of heat stroke in Texas and Arizona did not cause it. The families skipping meals because grocery bills have outrun their budgets did not cause it. But they are paying for it in skipped meals, in hospital bills, in the quiet emergency that food insecurity always is, and that extreme heat has a particular capacity to deepen and accelerate.

The question is whether those with the power recognize that climate change and particularly the increasing heat and heatwaves are causing the devastating impacts across the country and whether they respond to these problems at the scale the crisis demands. They need to protect the nutrition assistance that stands between food price volatility and mass hunger, build the heat crisis infrastructure that will make survival equitable, and invest in the agricultural resilience and international food security that prevent the spiral from going further.

The temperature records keep breaking. The warning has been issued, again and again, in thousands of scientists are studying climate change around the world and so we have the data, we know what will come next if we do not act and we know how to halt and reverse the climate crisis. What remains is whether the leaders in power will take the actions necessary to transition to clean energy and take actions at scale. We must act!

The shoreline is not where you think it is. To a geologist, a tide gauge analyst, or a corn farmer staring at a field going white with salt crust, the shoreline has been moving inland for decades, measured in millimeters of sea-level rise per year, at a pace easy to dismiss until suddenly it is not. Across the coastal plains of Maryland, Virginia, Delaware, North Carolina, and Louisiana, relative sea level rise (RSLR) is converting the most productive agricultural land in the region into salt marsh, at a rate that no crop rotation schedule and no drainage ditch installation can fully outpace.

Over the three decades between 1993 and 2023, global mean sea level rose a cumulative of 101.4 mm, approximately four inches at a mean rate of approximately 3.6 mm rise per year.¹ That is already double the twentieth-century long-term average of 1.4 mm rise per year.² By 2024, tide gauge records across the contiguous United States recorded that the rate of sea-level rise had increased to a localized rate of approximately 4.3 mm per year, accumulating nearly 16 inches of relative sea level rise since 1900.³ Those numbers sound modest in the abstract. They are not modest on a farm.

This is not a crisis arriving someday, it is a crisis that has arrived today. A landmark multi-decadal study using 38 years of satellite imagery across the Mid-Atlantic found that sea marsh encroachment is nearly twice as fast, and 1.4 to 6.8 times more frequent on agricultural lands than on adjacent forestlands.⁴ Between 1984 and 2022, the seaward boundary of agricultural land across the Chesapeake and Delaware Bay watersheds moved upslope from an elevation of 0.74 meters to an elevation of 0.87 meters.⁵ That is not a natural shift in plant communities. That is the ocean claiming farmland, acre by acre, year by year, in the most productive coastal agricultural region in the eastern United States.

Fine-scale mapping of the coastal counties of Delaware, Maryland, and Virginia that was published in Nature Sustainability reveals that the land area covered by visible salt patches almost doubled between 2011 and 2017 alone, converting over 19,000 acres of working farmland into salt marsh.⁶ The direct economic losses to farmers from those visible salt patches exceeded $427,000. The indirect losses from reduced crop yields within 200 meters of salt patches are estimated at $39 million to $70 million annually.⁷ In Somerset County, Maryland, 3.5 square kilometers of agricultural land transitioned entirely to tidal wetland between 2009 and 2017.⁸ Across the broader region, cumulative farmland losses between 1984 and 2022 reached 557.4 square kilometers, 14.8 percent of total agricultural area, outpacing even the loss of forestland, despite the fact that farmland sits, on average, at higher elevations than the forests it is losing ground to.⁹

“The shoreline is not where you think it is. It has been advancing inland for decades, measured in millimeters per year, at a pace easy to dismiss — until the salt patches appear, the corn dies, and the marsh moves in.”

The sea does not only advance at the surface. It advances underground. Saltwater intrusion moves through both tidal channels and subsurface aquifers, reaching fields miles from any visible coastline. The dense networks of drainage canals and ditches that coastal farmers have built over generations to keep their fields workable by alleviating waterlogging and getting crops in the ground on schedule are, at the regional scale, the very infrastructure that accelerates the problem of salt water intrusion due to sea-level rise. Those low-resistance hydrological pathways are highways for high tides and storm surges, carrying saline water miles inland, into fields that should be freshwater systems.¹⁰

What Salt Does to a Farming Soil

When saltwater reaches an agricultural field, it does not merely wet the soil and drain away. It begins a sequence of biogeochemical processes that can permanently degrade the land’s productive capacity. The introduction of salt water, which is made of sodium (Na⁺) and chloride (Cl⁻) ions, into the soil solution of farmlands increases its osmotic potential, making it difficult for non-salt-tolerant crops to extract water even from soils that are technically saturated with water.¹¹Specific ion toxicities caused particularly from chloride stunt crop growth, disrupt photosynthesis, and cause necrotic leaf burn, defoliation, and complete germination failure. For a corn farmer, that is the end of a season potentially leading to bankruptcy1111.

Beyond those immediate crop effects, the sodium ions attack the soil structure itself. In sodic conditions, where Na⁺ saturates the cation exchange capacity of clay minerals, soil aggregates disperse. The macropore network that makes soil a functional medium for plant roots and drainage collapses. Hydraulic conductivity falls. The ground seals. The water sits. And when the water sits long enough, a sequence of microbial transformations begins from which the field may not recover.¹²

In a healthy coastal agricultural soil, significant stores of organic carbon are stabilized by binding to iron oxides in a process called mineral-associated organic matter (MAOM) formation. When saltwater intrusion creates anoxic, waterlogged conditions, anaerobic microbes use those iron compounds as substitute electron acceptors in their respiration, dissolving them in the process. That dissolution releases the associated organic carbon, which is rapidly mineralized into carbon dioxide and methane.¹³ A historical carbon sink becomes an active greenhouse gas source. Making climate change and sea-level rise worse. The soil’s nutrient-cycling capacity collapses along with its structure. Elevated chloride concentrations directly inhibit the nitrifying bacteria that convert ammonium to the nitrate forms that crops can use, making fertilizer applications increasingly ineffective.¹⁴

The Corn Economy and Its Salt Threshold

The economic stakes of this biogeochemical cascade are particularly severe for the Delmarva region and the broader coastal Mid-Atlantic because of its deep dependence on corn production. Corn is, by the measure of salt tolerance science, the most vulnerable of the major commodity crops. The Maas-Hoffman model, the foundational salt tolerance framework used by agricultural extension services and resource managers across the United States, defines the relationship between soil salinity and relative crop yield. For corn (Zea mays), the damage to crops from salt water begins at an electrical conductivity of the saturated soil extract of just 1.7 decisiemens per meter, a measurement that is the lowest threshold of any major commodity crop in production on the coastal plain.¹⁵

All other major crops can with stand much greater salt water damage: 1) barley (threshold: 8.0 dS/m), 2) wheat (6.0 dS/m), or even 3) sorghum (6.8 dS/m).¹⁶ In states like North Carolina, where saltwater intrusion is advancing through the low-lying agricultural landscapes of the Outer Coastal Plain, farmers are being forced off corn and onto lower-value sorghum. The farmers are making this change, not because they want to, but because the salt in their fields leaves them no choice. The margin compression in those communities, already economically vulnerable, is severe. Global annual economic losses from salt-degraded agricultural land are estimated at between $12 billion and $27.3 billion from reduced crop yields alone.¹⁷ The value of the lost farm land is multiples of that loss.

This slow-onset disaster extends far beyond the Mid-Atlantic. Ocean water is encroaching on freshwater aquifers in 43 states, destroying irrigation sources and introducing structural vulnerabilities to regional agricultural supply chains.¹⁸ The stakes reach their highest in California’s Sacramento-San Joaquin Delta, which serves as the freshwater hub for 20 million residents and irrigates the Central Valley, a region that produces more than half of the nation’s fruits, nuts, and vegetables. The question of whether that system remains a freshwater system is a question about whether California’s agricultural economy survives in its current form.¹⁹

“American farmers are being asked to absorb a geological and hydrological crisis they did not create, on top of a climate crisis driving the same saltwater intrusion, in communities that were already watching their margins thin and their neighbors sell.”

The Fisheries Crisis That Starts in a Marsh

The ecological and economic destruction of relative sea level rise does not stop at the farm field’s edge. It extends into the estuaries and nearshore ecosystems that serve as the biological engines of the American commercial fishing and shellfish industries. At least 50 percent of all commercially harvested fish and shellfish species in the United States, including shrimp, blue crabs, eastern oysters, menhaden, weakfish, and a range of demersal finfish, rely on estuaries and intertidal salt marshes as nursery habitats.²⁰ The wave-buffering capacity of those wetlands prevents an estimated $3 billion in storm damage annually.²¹ Both of those functions are in accelerating decline.

According to the U.S. Fish and Wildlife Service’s decadal Wetlands Status and Trends report to Congress, measuring change between 2009 and 2019, the contiguous United States lost 670,000 acres of vegetated wetlands, an area roughly the size of Rhode Island.²² Salt marshes experienced the largest net percentage reduction of any saltwater wetland category, declining by 2 percent or 70,000 acres.²³ That loss rate represents a 50 percent increase from the 2004–2009 study period. The trajectory is accelerating, not stabilizing.

Under natural conditions, salt marshes maintain their relative elevation by trapping sediment and accumulating organic peat. When sea level rise outpaces that vertical accretion, marshes migrate landward, colonizing low-lying uplands. But along the developed Atlantic and Gulf coastlines, that landward migration is blocked by seawalls, bulkheads, roads, and development in a phenomenon ecologists call coastal squeeze. Within the United States, approximately 14 percent of all shorelines have been hardened with artificial structures.²⁴ Those structures do not merely protect the land behind them. They sentence the marsh in front of them to drowning. Systematic reviews published in BioScience document that seawalls support 23 percent lower biodiversity and 45 percent lower organism abundance than natural shorelines.²⁵ The juvenile fish and shellfish that depend on that margin habitat have nowhere to go.

The Scallop Fleet, the Oyster Reef, and the Chemistry of Collapse

For marine species that have shells including oysters, scallops, clams, crabs, the physical threat of coastal squeeze is compounded by ocean acidification (OA). The ocean has absorbed roughly 30 percent of the anthropogenic carbon dioxide emitted since industrialization began in about 1850.²⁶ That carbon dioxide has seriously impacted the marine carbonate system, reducing the concentration of carbonate ions and lowering the saturation state of calcium carbonate, including aragonite and calcite, the minerals shellfish use to build and maintain their shells. The result, for larval oysters and juvenile scallops, is thinner shells, higher predation mortality, and mass die-offs in commercial hatcheries during acidification events.²⁷

The Atlantic sea scallop fishery, worth over $500 million annually, is the largest wild scallop fishery in the world and represents 77 percent of the commercial landings value of New Bedford, Massachusetts, America’s highest-value fishing port.²⁸ A landmark bioeconomic model published in PLOS ONE by Rheuban et al. (2018) projects that under a high CO₂ emissions scenario, wild sea scallop biomass may decline by more than 50 percent by the end of this century, with landings contracting by 10 to 30 percent as early as 2050.²⁹ The offshore fleet operating out of New Bedford, Gloucester, and Point Judith is not a distant abstraction of biodiversity loss. It is real people, real boats, and real communities whose economic futures are written in the chemistry of water they cannot change.

On the Pacific coast, ocean acidification has already cost the aquaculture sector an estimated $110 million and 3,200 jobs.³⁰ The Whiskey Creek hatchery in Oregon historically has supplied 75 percent of West Coast oyster larvae. It has experienced catastrophic larval mortality events tied directly to acidification before installing monitoring and buffering systems that partially restored production. In Alaska’s Bristol Bay, the NOAA Ocean Acidification Program documents OA as a primary driver of long-term red king crab decline, contributing directly to the complete commercial fishery closures during the 2021–2022 and 2022–2023 seasons.³¹ Those closures did not merely hurt fishers. They erased the economic foundation of remote coastal communities that have no alternative industry to fall back on.

The Eastern oyster industry, generating approximately $250 million annually along the Gulf and Atlantic coasts, is suffering from the convergence of salinization, reef erosion, and acidification, disrupting the physiological cues that govern spawning and juvenile settlement.³² Projections indicate that an intermediate sea level rise of 1.2 meters by 2100 will eliminate 83 percent of existing coastal marshes and 26 percent of seagrass beds across the Mid-Atlantic shelf, leading to steep declines in commercial catches of blue crabs and shrimp.³³ The marine food production ecosystem of the American eastern seaboard is being dismantled, one lost inch of marsh, one acidified larval cohort, one closed fishery at a time.

The Pathogen Nobody Talks About Until People Die

Relative sea level rise is not only dissolving wetlands and collapsing fisheries. It is also expanding the geographic range of one of the most lethal bacterial pathogens in the American food supply. Vibrio vulnificus is a halophilic, gram-negative bacterium that occurs naturally in warm, brackish estuarine waters. It is the leading cause of seafood-related deaths in the United States, responsible for 95 percent of all domestic seafood-associated fatalities, primarily through the consumption of raw oysters.³⁴ Its clinical mortality rate from primary septicemia ranges from 15 to 50 percent.³⁵ It is not a marginal risk. It is a serious and growing public health crisis whose geography is being actively redrawn by sea level rise.

The proliferation of V. vulnificus is tightly constrained by two environmental parameters: water temperature (16°C to 33°C) and salinity (5 to 20 parts per thousand). Historically, the optimal brackish salinity corridor was confined to the middle reaches of tidal estuaries. The fresh reaches upstream were too fresh; the coastal ocean boundaries too saline. As rising seas push the salt wedge upriver, that optimal corridor migrates into formerly freshwater reaches of coastal rivers, dramatically expanding the volume of water capable of hosting high pathogen concentrations.³⁶

Empirical modeling demonstrates that sea level-driven shifts in salinity gradients have a significantly greater impact on future V. vulnificus exposure risk than atmospheric temperature increases alone.³⁷ In estuaries such as Winyah Bay, South Carolina, predictive models indicate that SLR-driven salinity shifts will increase exposure risk by up to four times, with the most severe increases occurring at upriver sites that currently face zero baseline risk.³⁸ This range expansion is already manifesting clinically. Cases and fatalities are emerging in Long Island, Connecticut, and Rhode Island - regions historically considered too cold and too fresh to support dense Vibrio populations. Following the coastal flooding of Hurricane Ian in 2022 and Hurricane Helene in 2024, Florida reported unprecedented spikes in vibriosis, with over 74 cases and 17 deaths in counties flagged as high-risk by predictive models.³⁹

“The fish are moving north. The salt is moving inland. The bacteria are following the salt. And the fishing communities cannot move at all — constrained by their boats, their docks, their debt, and the only place they have ever called home.”

The Regulatory Cost of a Warming Bay

Because of the lethality of V. vulnificus, federal and state regulators impose strict sanitary controls on the commercial shellfishery under the National Shellfish Sanitation Program (NSSP) and the FDA. These mandates enforce operational and post-harvest protocols that are non-negotiable and increasingly expensive. Oysters harvested for raw consumption must be placed under mechanical refrigeration within 10 hours of harvest to keep internal temperatures below the pathogen growth threshold.⁴⁰ In an unrefrigerated transport vehicle, Vibrio levels can double in fewer than 15 minutes on a warm summer day. States are legally required to implement a Vibrio Control Plan if two or more confirmed V. vulnificusinfections occur within the preceding 10 years. When case thresholds are exceeded, implicated harvest areas are closed for 7 to 21 days, and oysters must test below 10 pathogenic bacteria per gram of meat before reopening.⁴¹

Post-harvest processing techniques like high-pressure processing, irradiation, low-temperature pasteurization, flash-freezing all reduce Vibrio densities and cut oyster-associated illnesses by 40 to 60 percent, but they require significant capital investment that is out of reach for many small-scale coastal producers.⁴² The regulatory burden is not unreasonable, given what the pathogen does. But it lands hardest on the waterman operating out of a small lease on a tidal creek, not on the industrial processor with a capitalized processing facility. As sea level rise expands the Vibrio risk zone upriver and northward, more harvest areas, more operations, and more communities face those compliance costs and closure exposures.

The Fish Are Moving, But the Boats Cannot Follow

Climate-driven restructuring of marine ecosystems is not merely a future projection. NOAA bottom trawl survey data from the Northeast Shelf, compiled over nearly 50 years, documents an average species distribution shift of almost 8 miles northward and 8 feet deeper per decade.⁴³ The fish are moving to stay within their physiological thermal envelopes, following the isotherms as warming pushes them poleward and into deeper, colder waters. The boats, the processing plants, the fish houses, and the docks cannot follow. They are fixed to geography and capital in ways that fish are not.

This spatial mismatch between migrating stocks and stationary infrastructure is documented in studies of Florida fishing communities including Cedar Key, Conch Key, and Fort Myers Beach.⁴⁴

These communities, the fishers that work there report with consistent and sometimes painful specificity the regular tidal flooding of main coastal roads, a significant northward migration of warm-water species like snook, the complete disappearance of historically productive shallow oyster reefs, and a one-month delay in the arrival of the annual winter cold front that once structured the clamming and oystering calendar.⁴⁶ The reefs are gone. The road floods. The cold front is late. The economic loss accumulates.

Who Bears the Weight: The Communities on the Receiving End

The communities experiencing these losses include the coastal agricultural counties of the Delmarva Peninsula and the North Carolina Outer Coastal Plain, the fishing communities of the Gulf Coast and the Chesapeake Bay, the small-scale shellfish growers of the Pacific Northwest and Maine. These are not communities with the greatest capacity to absorb systemic economic shocks. They are rural. They are often economically marginalized. Their tax bases and public services are thin. When a principal industry is degraded by a slow-onset climate change driven geophysical process that receives no emergency declaration and mobilizes no disaster fund, there is no cavalry coming.

The national food security consequences of the losses already documented are significant. Saltwater intrusion is encroaching on freshwater aquifers in 43 states, threatening irrigation systems across a far broader geography than the Atlantic coastal plain.⁴⁷ The degradation of the Chesapeake Bay watershed’s productive agricultural and aquatic ecosystems is a degradation of a regional food system that feeds millions. The collapse of the Mid-Atlantic marsh edge is a collapse of the nursery habitat that sustains commercial fishing from Maine to Florida. These are not local losses. They are national vulnerabilities being slowly accumulated, one acre and one season at a time.

“The coast is not a boundary between land and water. It is the most productive interface in American food production and it is being disassembled, one marsh acre, one salt patch, one closed fishery at a time, by a crisis whose pace makes it easy to ignore until it is too late.”

What Must Change: Policy Proportionate to the Threat

The political response to the accelerating damage to the American coastal agriculture and fisheries has been pathetic compared to the threat nor well-matched to its geography. There is no shortage of knowledge about what is happening or what works to fix it. The failure is taking that knowledge and creating well funded, scaled, and sustained policy action.

I. Protect and Expand the Agricultural Conservation Easement Program

The USDA Natural Resources Conservation Service administers the Agricultural Conservation Easement Program (ACEP), including its Wetland Reserve Easements (WRE) component, which compensates farmers to voluntarily retire salt-degraded agricultural land from production and restore it to functioning wetland. The program works.⁴⁸ It is competitive and chronically underfunded, leaving many of the most vulnerable coastal farmers without options when their field become damaged by sea-level rise. State departments of agriculture along the Atlantic and Gulf coasts should establish matching grant programs to supplement federal ACEP enrollment, ensuring that farmers facing the most acute salinization pressures have a viable path to retirement that does not require walking away from land their families have worked for generations without compensation.

Under permanent easements, the NRCS compensates landowners at 100 percent of easement value and covers 75 to 100 percent of restoration costs.⁴⁹ The 30-year and term easement options offer compensation at 50 to 75 percent of the permanent rate for landowners who are not ready to make a permanent commitment.⁵⁰ These programs align short-term farm income with long-term ecological retreat, providing a dignified off-ramp from a crisis that, without this program or something similar, will leave farmers with degraded land, no income, and no compensation.

II. Publish Standardized Assisted Marsh Migration Protocols

When salt-degraded farmland transitions to tidal wetland, the process can be managed or it can be chaotic. Assisted marsh migration, the deliberate facilitation of inland wetland expansion through landform modification, invasive species removal, and native planting produces ecologically functional wetland habitat faster and with greater species diversity than unassisted transition.⁵¹ Federal and state agencies should publish standardized technical guidelines establishing clear criteria: restricting assisted migration to sites with slopes below 1 percent; requiring the excavation of hydrological runnels to prevent upland ponding that drowns colonizing vegetation; mandating exclusion of contaminated brownfield sites from migration corridors. The USDA NRCS Cape May Plant Materials Center has documented the native species best suited for these buffer zones, including groundsel (Baccharis halimifolia), bayberry (Morella pensylvanica), salt meadow cordgrass (Spartina patens), and switchgrass (Panicum virgatum).⁵² That knowledge exists. The standardized protocols to disseminate it broadly do not.

III. Rebuild Living Shorelines and Stop Incentivizing Hardening

State and federal coastal management agencies should replace policies that incentivize shoreline hardening such as building seawalls with programs that give structural preference to living shoreline alternatives: oyster reef restoration, marsh sill construction, and hybrid beach-marsh complexes. Seawalls and bulkheads support 23 percent lower biodiversity and 45 percent lower organism abundance than natural shorelines.⁵³ They do not merely fail to provide nursery habitat. They actively degrade it through wave reflection, scour, and the physical severing of the marsh-upland transition zone. Hard armoring permits should be approved only after living shoreline alternatives have been evaluated and documented as infeasible.

Along the Gulf Coast, where Louisiana loses approximately 80,000 acres of coastal wetlands annually due to levee-induced sediment starvation,⁵⁴ restoration of natural sediment delivery pathways through controlled river diversions - a strategy evaluated in the Louisiana Coastal Master Plan - should be treated as a highest-priority resilience investment, not a perpetually deferred engineering study. The Coastal Wetlands Planning, Protection, and Restoration Act should be reauthorized and expanded with funding levels that reflect the scale of documented loss. The current Administration is going in exactly the opposite direction to the detriment of coastal famers and fishers.

IV. Scale the Early Warning and Buffering Infrastructure for Shellfish

Hatcheries across the Pacific coast have demonstrated that real-time water chemistry monitoring using Burke-o-Lator systems, combined with soda ash buffering and three-day oceanographic forecasting through the LiveOcean model, can recover up to 75 percent of larval losses attributable to ocean acidification events.⁵⁵ Federal funding under the Bipartisan Infrastructure Law should be prioritized to subsidize Burke-o-Lator installations in hatcheries from Alaska to Maine and to extend the LiveOcean forecasting portal to the Atlantic seaboard. Co-location of eastern oyster and hard clam leases adjacent to restored eelgrass (Zostera marina) beds which draw down dissolved CO₂ through photosynthesis, biologically raising local pH provide a low-cost, ecologically synergistic buffer against acidification that the Chesapeake Bay and Gulf estuaries can deploy now.⁵⁶ There just needs to be some political will and spending on people instead of wars.

V. Build a National Vibrio Early Warning System

The FDA, in partnership with NOAA and the CDC, should scale the University of Florida’s satellite-derived Vibriopredictive model into a national public health early warning system. The system should integrate real-time sea surface temperature and salinity data to map the shifting brackish salinity corridor up to one month in advance, giving shellfish growers the information to plan harvest locations safely. It should replace static, rolling five-year average risk calculations with dynamic predictive advisories, and combine satellite forecasting with rapid pathogen detection at commercial landings to identify contaminated product before it enters the raw supply chain.⁵⁷ As the optimal Vibrio salinity corridor migrates upriver and northward, the geographic coverage of any effective early warning system must expand with it. We have the technology and with AI modelling the early warnings can be highly accurate.

VI. Fund Coastal Community Transition Plans

NOAA’s Sea Grant program, in partnership with state marine fisheries agencies, should develop and fund Community Climate Transition Plans for coastal fishing communities facing compounding stressors. Plans developed through participatory action research with fishing communities, integrating economic diversification pathways, targeted retraining programs, and working waterfront preservation, can bridge that gap in ways that top-down adaptation mandates cannot.

The Slow Emergency

The United States has long told itself a story about its agricultural and maritime abundance that makes it difficult to reckon with the evidence of what is being lost. The story is not false. The productivity of American coastal agriculture and fisheries is extraordinary. But it rests on a physical and ecological foundation where we have freshwater aquifers, intact salt marshes, functioning estuaries, carbonate-saturated coastal waters, and stable salinity gradients. Now, sea level rise is systematically degrading, season by season, millimeter by millimeter our coastal farms and fisheries.

The farmers watching their corn fields go white with salt are not the authors of that crisis. The watermen whose oyster reefs have eroded into tidal flat are not either. The communities in North Carolina where sorghum has replaced corn because the salt threshold arithmetic has simply made growing corn impossible, are not the problem. The Bristol Bay crab fleet that lost two seasons of commercial harvest to an acidification-driven population collapse did not cause the CO₂ that acidified the water.

But they all are paying for it. They are paying in lost income, in degraded land, in marginal profitability calculations that no longer compute, in communities that are slowly losing the economic basis for their continued existence. The question, as it always is, belongs to the people in a position to respond at scale. The science is not uncertain. The losses are documented and accelerating. The policy tools involve easements, living shorelines, early warning systems, hatchery technology, assisted marsh migration, community transition plans that already exist and have demonstrated results and could be made better with appropriate funding and new technologies.

“The sea does not care about the political calendar. It does not wait for funding cycles or legislative compromise. It moves at the pace of physics. The only question is whether policy can change and be made to move at the pace of documented losses.”

The slow emergency of sea level rise is not slow because it is not serious. It is slow because its pace allows the Politicians and top 1% to look away, to defer, to argue about whether the millimeter measurements of one decade should govern the policy decisions of the next. The 19,000 acres of Delmarva farmland already converted to salt marsh cannot be retrieved.⁵⁹ The Bristol Bay crab seasons already closed cannot be fished back.⁶⁰ The larvae that died in Pacific hatcheries before monitoring and buffering systems were installed cannot be recovered. The question is only how much more of the same is acceptable and what it will take for the people responsible for creating a response to save our coastal farms and fisheries to create and fund one that is proportionate to the scale of the loss.

Hunger is rising. After decades of slow but steady progress, the number of people facing food insecurity has surged. According to the Food and Agriculture Organization of the United Nations (FAO), 2.3 billion people faced moderate or severe food insecurity in 2024. More and more people are facing a hunger crisis particularly since 1/3 of the world’s fertilizer is being held up due to the war in Iran and crops are being planted now which need that fertilizer.^[1] The drivers are multiple, but one has become impossible to ignore: climate change is systematically undermining the world’s ability to grow, distribute, and afford food.

The Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (2022) identifies food security as one of the most critical and immediate risks of a warming planet. It finds that climate change has already reduced global agricultural productivity growth by roughly 21% since 1961, with the losses concentrated in low- and middle-income tropical countries — precisely where food insecurity is already highest.^[2] For staple crops, the trajectory is alarming: maize yields are projected to fall by up to 24% under high-emissions scenarios; wheat and rice face comparable losses. For every 1°C rise in global average temperatures, food production declines by the caloric equivalent of forcing one person in every household on earth to skip a meal every week.^[3]

These are not distant projections. They are unfolding now. The prolonged drought that gripped the Horn of Africa from 2021 to 2023 — described by meteorologists as the worst in 40 years and made significantly more likely by human-caused climate change^[4] — pushed 22 million people across Ethiopia, Kenya, and Somalia into acute food insecurity.^[5] In the Central American Dry Corridor, multi-year droughts have destroyed consecutive harvests, driving malnutrition, stunting, and mass displacement. In 2024, extreme heat and El Niño conditions devastated West African cocoa harvests and Vietnam’s coffee crop, sending global commodity prices surging — with none of the gains flowing to the farmers who grew them.

“For every 1°C rise in temperature, a poor smallholder farmer loses more than half their income. For a billionaire investor, the same degree of warming represents a new profit opportunity.”

The Crop Collapse: Science on the Front Line

The relationship between warming temperatures and crop failure is now one of the most robustly documented findings in climate science. A landmark 2025 study published in Nature modelling global production across all major crops confirmed that current trajectories will produce significant and widespread yield declines across cropping regions by mid-century, with the greatest impacts concentrated in sub-Saharan Africa, South Asia, and Central America.^[6]

Pastoralism — the livelihood of more than 75% of the global population in the world’s dryland regions — is equally exposed. The IPCC Special Report on Climate Change and Land (2019) documents falling pasture productivity, damage to animal reproductive function, and accelerating biodiversity loss as rainfall patterns shift and temperatures rise.^[7] For the estimated 200 million pastoralists worldwide, these are not abstract risks — they are the destruction of livelihoods that have no equivalent substitute.

The majority of cropping regions have now experienced both rapid warming and atmospheric drying, affecting an area home to one fifth of the global population.^[8] Yield progress for barley, wheat, and maize — the crops on which global food security most depends — has slowed significantly as a direct result of climate stress. The world is running a food security deficit even before accounting for the full consequences of future warming.

Smallholder Farmers: The People Who Feed the World Are Going Hungry

Smallholder farmers produce over a third of the world’s food, and approximately 2.5 billion people — including the vast majority of the world’s most food-insecure populations — depend on small-scale farming, herding, and fishing for their survival.^[9] These are the people most exposed to climate change and least equipped to adapt to it.

The economic consequences are stark. A study from Kansas found that for every 1°C of warming, net farm income fell by 66%.^[10] Research from India documents a 17–21% decrease in farm revenue per degree of warming.^[11] A broader analysis finds that a 1°C increase in average temperatures is associated with a 53% decrease in the farm incomes of poor rural households globally. These losses are not recovered in good years — they accumulate, compounding across seasons, pushing households into debt, into hunger, and ultimately into migration.

Women farmers, who make up 43% of the global agricultural labour force, bear a disproportionate share of this burden.^[12] A study in France found women are overrepresented in the crops most vulnerable to climate variability, yet more likely than men to adopt sustainable practices — managing a third of organic farms while comprising less than a third of permanent agricultural workers.^[13] In Bangladesh, climate disasters directly destroy the small livestock, homestead gardens, and informal trading that women rely on for income and nutrition, with limited access to land, credit, or social protection making recovery extremely difficult.^[14]

Climateflation: How a Warming World Is Making Food Unaffordable

Even where food remains available, it is becoming unaffordable. A phenomenon researchers have begun calling ‘climateflation’ — food price inflation driven by climate-related supply disruptions — is now a documented and measurable economic force. A 2024 study published in Nature Climate Change found that global temperature increases projected for 2035 will add between 0.92 and 3.23 percentage points to annual food price inflation.^[15] Food prices in Europe are forecast to rise by up to 50% due to global warming over coming decades.^[16]

These headline figures translate differently across the income spectrum. In Nigeria, a person allocates nearly 60% of their household budget to food; in the United States, the figure is less than 7%. When food prices rise, the poorest households have nowhere to absorb the shock — they eat less, they eat worse, they pull children from school, they take on debt.^[17] In the United States itself, the lowest income group already spends a third of its budget on food; climate-driven price rises will hit them hardest even in the world’s wealthiest economy.

A team of experts convened by the European Climate Research Institute (ERL) in 2025 investigated climate-linked food price spikes across 18 countries between 2022 and 2024, documenting how heat, drought, and extreme precipitation events each generated measurable and sustained price increases for staple commodities.^[18] In every case studied, the price increases persisted long after the climate event had passed: between September and October 2023, the FAO’s global food price index fell by 11.5%, yet domestic food prices across low- and lower-middle-income countries continued to rise, with the poorest country group recording price increases of 30%.^[19]

Who Profits When Food Systems Fail

The costs of climate-driven food crises are not distributed evenly across the supply chain. While smallholder farmers lose incomes and low-income consumers skip meals, the corporations that dominate the global food system have used climate-related supply disruptions as cover for extraordinary profit-taking.

The four corporations — Archer-Daniels-Midland, Bunge, Cargill, and Louis Dreyfus — that together control an estimated 70–90% of global grain trade saw their profits surge following Russia’s invasion of Ukraine and the associated global food price spike. Cargill’s profits rose by 23% in 2022 compared to 2021; ADM recorded its highest profits in its history.^[20] Ten hedge funds made an estimated $1.9 billion in profits ahead of the food price spike, through speculative positions on food commodities.^[21]

Climate shocks have become a mechanism for further concentration of profit at the top of food supply chains. In 2024, extreme weather and El Niño conditions destroyed West African cocoa harvests, sending prices up 231% year on year — with none of that increase reaching the cocoa farmers who had lost their crops.^[22]Drought in Brazil and Vietnam drove coffee prices up 55% by August 2024, while the trading companies that serve as middlemen in the supply chain captured the margin.^[23] The avian influenza outbreak — a climate-sensitive zoonotic risk — killed over 120 million hens, tripling retail egg prices in the US, while major producer Cal-Maine reported $509 million in a single quarter: more than triple its previous year’s results.^[24]

Cargill — one of the world’s largest food traders — now counts 12 family members as billionaires, up from eight before the pandemic.^[25] The food industry’s billionaires are enriching themselves from the same climate crisis that is starving the farmers who grow their commodities and pricing out the consumers who buy their products.

“Climate change is not just destroying harvests — it is restructuring who controls the food system and who goes hungry as a result.”

The Politics of Hunger: Inequality, Power, and the Failure to Act

The link between climate change and hunger is not a natural disaster — it is a political one. The countries that are most food-insecure today contributed least to the emissions that are destroying their agricultural systems. The people going hungry in the Dry Corridor of Central America, in the dryland communities of the Sahel, and on the flood-prone deltas of Bangladesh did not cause the climate crisis. The people who did — the billionaire investors in fossil fuel companies, the executives who lobbied against climate regulation, the owners of the private jets — are insulated from its food consequences by their wealth.

Between 1850 and 2015, the countries of the Global North, representing just 14% of the world’s population, were responsible for 92% of carbon dioxide emissions in excess of the safe planetary boundary.^[26] Analysis combining the Stockholm Environment Institute’s emissions inequality data with climate attribution science finds that the richest 1% of humanity contributed 26 times more to extreme weather events than the average person — including the droughts, floods, and heat extremes that are now driving food system collapse.^[27]

The Corporate Capture of Agricultural Systems

The food crisis is not simply a story of weather — it is also a story of market power. A small number of agro-industrial corporations have come to control critical nodes of the global food system. Four firms — Syngenta Group, Bayer, BASF, and Corteva — now control half the world’s commercial seed supply and more than half the global pesticides market.^[28] These same corporations are marketing climate-related crop failures as an opportunity to sell ‘climate-smart’ technologies — new seeds, new inputs, new contracts — that deepen farmer dependency on corporate supply chains rather than building genuine resilience.

Large-scale agribusinesses in the US and EU receive billions in public subsidies that allow them to sell imported staple crops — wheat, rice, corn, soy — at prices below what local farmers can compete with.^[29] This structural unfairness is compounded by climate vulnerability: smallholder farmers in the Global South face the double burden of competing with subsidised industrial agriculture and absorbing the climate shocks that industrial agriculture’s emissions have caused.

Roughly 21–37% of global greenhouse gas emissions originate from the food system itself, from farming and land use to storage, transport, processing, retail, and consumption.^[30] The industrial model that dominates global food production is both a major driver of the climate crisis and the primary beneficiary of the instability that crisis creates. This is not a market failure — it is the market functioning exactly as designed, concentrating gain at the top while socialising cost and risk onto those at the bottom.

What Must Change: From Crisis to Justice

The evidence demands a response proportionate to the scale of the crisis. Techno-managerial fixes — new seed varieties, precision agriculture, carbon markets — are not sufficient, and in many cases actively entrench the corporate power structures that are making the crisis worse. The path from climate-driven hunger to food security runs through structural change: in land rights, in trade rules, in corporate accountability, and in who controls the food system.

Governments must move away from industrial monoculture agriculture and invest in climate-resilient smallholder food systems. This means protecting farmers’ access to arable land, community seed banks, and agricultural inputs; funding agroecological research and practice; and reforming trade rules that allow rich-country subsidy regimes to undercut farmers in climate-vulnerable nations.^[31]

Women’s role in transforming food systems must be recognised and resourced. Policy biases and structural barriers that restrict women’s access to land, credit, agricultural inputs, and markets must be dismantled.^[32]The rights of Indigenous Peoples, pastoralists, and smallholder farming communities to manage their lands and integrate into national adaptation plans must be protected and funded through accessible climate finance — not through the loan-based instruments that have already placed low-income nations under crippling debt burdens.

And the corporations and billionaires who have profited from the food system’s failures — and whose emissions have helped create the conditions for those failures — must be made to pay. Windfall profit taxes on food corporations that price-gouge during climate-driven supply shocks; wealth taxes on the billionaires whose investment emissions contribute disproportionately to the warming that is destroying harvests; and mandatory corporate accountability for emissions across agricultural supply chains are all tools available to governments willing to use them.
