NASA Study Finds Carbon Emissions Could Dramatically Increase Risk of U.S. Megadroughts
Droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years, according to a new NASA study. The study, published Thursday in the journal Science Advances, is based on projections from several climate models, including one sponsored by NASA. The research found continued increases in human-produced greenhouse gas emissions drives up the risk of severe droughts in these regions. Read more
'Megadrought' likely for western U.S. by end of century
The consequences of climate change paint a bleak picture for the Southwest and much of America's breadbasket, the Great Plains. A "megadrought" likely will occur late in this century, and it could last for three decades, according to a new report by Cornell and NASA researchers in the journal Science Advances (Feb. 12), an online publication of the American Association for the Advancement of Science.
