BBC : A new analysis of climate models by Ben Cook of NASA’s Goddard Institute for Space Studies and his colleagues suggests that the US is likely to experience droughts on a scale unseen in nearly 1000 years. Cook’s team combined reconstructions of past climate conditions and compared the data with 17 future climate models. According to their analysis, after 2050 the central and southwestern parts of the US will probably shift to conditions that will make them susceptible to decade-long droughts. The researchers also found that if current climate change rates are unchanged, there’s an 85% chance that a 35-year-long drought will occur in those regions.
