Climate change could spur stronger crop-wilting heatwaves that hit several of the world’s major grain producing regions simultaneously, potentially sparking food shortages and unrest, researchers warned Monday.

According to a report at Reuters, crop failures in one part of the world -- from weather disasters or other causes -- have traditionally been offset with increased trade from other areas with normal or above normal harvests, said climatologist Dim Coumou, a co-author of the study published in the journal Nature Climate Change.

Most vulnerable are the western regions of North America, western Europe, and western Russia and Ukraine, which together grow about a quarter of the world’s staple grains such as wheat, maize, soy and rice, are very susceptible to such heatwaves.
