# Heat, not drought, will drive lower crop yields, researchers say | Cornell Chronicle

> Cornell researchers, publishing in Environmental Research Letters on May 24, predict climate-driven heat stress will reduce yields of several major US crops more than drought stress later this century. The study uses decades of observed data to resolve a debate between crop models and statistical models.
