Mapping the 2012 Extreme U.S. Drought - The U.S. is currently in the grips of its worst drought since 1956, with little hope for near-term, widespread drought relief in sight. The drought is having major impacts on agriculture, particularly this year's corn harvest, which is expected to come in significantly lower than initial expectations. In fact, it's likely that the total economic damages of the drought are already greater than one billion dollars . . . and rising.
