The U.S. Southwest Could Soon Experience Decades-Long "Megadroughts"

During the 1930s, America's High Plains were ravaged by an 8-year long drought, resulting in the dreaded Dust Bowl. Scientists now warn that, owing to global warming, this could happen again — and that by next century many parts of the world could experience "megadroughts" lasting for several decades. » 8/28/14 8:00am Thursday 8:00am
