A new study warns that the chances of western states in the U.S. experiencing a multi-decade 'megadrought'—not seen in historical climate records in over 2,000 years—has a much higher chance of occurring in the decades ahead than previously realized. In fact, scientists are warning, the drought now being experienced in California and elsewhere could be just the beginning of an unprecedented water crisis across the west and southwest regions of the country.
