Water Shortage Seen Worsening on Climate Change in Potsdam Study

Water scarcity will increase around the world due to climate change, with more than 500 million people affected if mean global warming is limited to 2 degrees Celsius (3.6 degrees Fahrenheit), based on modeling studies by the Potsdam Institute for Climate Impact Research, or PIK.

An additional 8 percent of humankind may face new or worse water scarcity with 2 degrees warming, the target set by international climate negotiators, the German government-funded institute wrote in a news release today.  That could reach 13 percent in the case of a 5-degree-Celsius rise, which is probable if climate change goes on unchecked, PIK said.
