But for Lew Ziska, an associate professor of environmental health sciences at Columbia University who has studied the effects of climate change on crops, warmer conditions mean more transpiration. Asked whether more corn sweat is an effect of climate change, he said simply, “Yes.”He also noted increasing demand for corn to go into ethanol. Over 40% of corn grown in the U.S. is turned into biofuels that are eventually guzzled by cars and sometimes even planes.
