Climate Change & Crops
Extreme heat and drought are colliding across large swaths of the United States, damaging crops in the process.
A new study shows that drought exacerbates crop damages from heat, and that drier heat waves from our warming climate may cut global corn and soybean yields by 5% globally.
Corn production is expected to fall across much of the U. S., with especially strong declines in Missouri, Kansas, and the Carolinas. Because the harvest is larger in portions of Nebraska, Iowa, and Illinois, the economic impacts are potentially higher in these locations.
Soy production is also expected to drop, with the largest declines in Oklahoma and Kansas. Compared to recent and historical harvests, the economic impacts are likely to be largest along the Missouri and Mississippi River Valleys.
Record heat, intense drought, and a global pandemic are compounding to put complex pressures on food security worldwide.
