A Scientific Reports study using regression on observational data finds extreme dry heat sharply reduced US corn and soybean yields. Humid heat had little effect and in some areas boosted yields.
The authors argue that conflating the two types of heat underestimates yield sensitivity to dry heat.
The findings refine how heat-stress yield losses are modeled, which can affect crop forecasts. The direct price impact is limited because it is a research result, not a new supply event.
