A handful of U.S. states are facing significant strains on their water supplies that will only intensify with global heating, according to new rankings. New Mexico tops the list and is the only state with “extremely high” pressures on its water availability. California ranks second, followed by Arizona, Colorado and Nebraska. Experts with the World Resources Institute said the data shows a global water crisis. The U.S. overall is not among the world’s most at-risk countries. (The Guardian)
