Almost three-quarters of drought-prone regions around the world will be at risk of extreme water shortages known as "day zero droughts" by 2100 if emissions aren't reduced, and a third of these regions could be hit before 2030, according to a new study. Areas under threat include cities in the U.S., the Mediterranean and southern Africa.
