MIT finds climate change could impact water supplies dramatically

It’s no simple matter to figure out how regional changes in precipitation, expected to result from global climate change, may affect water supplies. Now, a new analysis led by MIT researchers has found that the changes in groundwater may actually be much greater than the precipitation changes themselves. Conversely, the analysis showed in some cases just a 20 percent decrease in rainfall could lead to a 70 percent decrease in the recharging of local aquifers — a potentially devastating blow in semi-arid and arid regions. The research was conducted by Gene-Hua Crystal Ng, a postdoctoral researcher in MIT’s Department of Civil and Environmental Engineering (CEE), along with King Bhumipol Professor Dennis McLaughlin and Bacardi Stockholm Water Foundations Professor Dara Entekhabi, both of CEE, and Bridget Scanlon, a senior researcher at the University of Texas. The results were presented Wednesday, Dec. 17, at the American Geophysical Union’s fall meeting in San Francisco. Read more.
