"One out of three U.S. counties is facing a greater risk of water shortages by mid-century due to global warming, finds a new report by Tetra Tech for the Natural Resources Defense Council.
For 412 of these counties the risk of water shortages will be "extremely high," according to the report, a 14-fold increase from previous estimates.
