Then they had to back down and correct the original, when they found the drought PDSI (Palmer Drought Severity Index) numbers were overestimated by double the amount:

Update – July 3, 2012

This news release has been revised to reflect a miscalculation in the original study that inadvertently resulted when simulations of historical drought were combined with simulations of future drought. The revised maps, below, indicate that drought levels on the Palmer Drought Severity Index may reach -10 in certain regions, whereas the levels reached -20 on the original maps. Similarly, upper-latitude areas become less moist than previously projected. Large portions of the globe are still expected to…
