Climate change cuts crop yields, even with adaptation efforts: Study
- A 2025 study led by a University of Illinois researcher projects that, despite adaptation measures, global yields of the six primary staple crops could decline by around 25% by the end of the century due to climate change.
- The study analyzed data from over 12,000 regions in 55 countries and found wealthier breadbasket regions face larger losses due to warming of about 3°C by 2100, roughly our current trajectory.
- Corn and wheat, especially in the U.S., Canada, China, and Russia, are projected to decline by 30 to 40%, while rice is more adaptable and may avoid large losses under warming.
- Hultgren noted that the regions facing the greatest risks tend to suffer the most significant losses, estimating that each 1°C rise in temperature would reduce food availability by about 120 calories per person each day.
- The study warns that such yield declines could lead to higher food prices globally and raise concerns over food security and political stability, especially in poorer countries with limited adaptation resources.

Climate change will reduce the planet's ability to feed: even if agricultural practices are adapted, global calorie yields of six major crops, including wheat or rice, will be 11-24% lower by 2100, according to a study published on Wednesday in Nature. ...
'We’ve never confronted anything like this': Expert warns of 'major problem' facing global food supply
The 1973 dystopian sci-fi movie "Soylent Green "— which starred Charlton Heston and Edward G. Robinson and took place in 2022 — depicted a hellish world in which widespread pollution and global warming had led to severe food and water shortages as well as widespread hunger and desperation. Now, in 2025, a newly released study finds that severe weather is threatening crops in a major way — and that the production of some key crops in the United S…
Study finds tree trunk breathing adaptation cools climate predictions
An international research team led by Chinese scientists has for the first time proposed a theoretical model to explain and predict the thermal adaptation of tree trunk respiration.The team established a global database of plant trunk respiration, and
A research team from the University of Illinois and other institutions published the results of an analysis in the British scientific journal Nature on the 18th, stating that of the six types of crops eaten as staple foods around the world, only rice may be able to avoid a significant drop in yield even if global warming progresses. However, they point out that the overall yield of staple crops is expected to decrease significantly, increasing t…
Water rights shape crop yield and revenue volatility tradeoffs for adaptation in snow dependent systems
Irrigated agriculture in snow-dependent regions contributes significantly to global food production. This study quantifies the impacts of climate change on irrigated agriculture in the snow-dependent Yakima River Basin (YRB) in the Pacific Northwest United States. Here we show that increasingly severe droughts and temperature driven reductions in growing season significantly reduces expected annual agricultural productivity. The overall reductio…
