New research suggests wheat crops may be threatened by unprecedented heat and drought

The world is getting hotter, causing shifts in seasonal patterns and increasing the amount of extreme weather such as severe droughts and heat waves, which can affect crop yields and food supplies. A recent study led by a researcher at the Friedman School of Nutrition Science and Policy at Tufts University has found that the likelihood of extreme temperatures that could affect crop yields has increased significantly in wheat-producing regions of the U.S. and China.
