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.
