The Washington Post reports: Vastly more Americans will be exposed to dangerous heat waves in future decades because of a combination of rising temperatures and rapid population growth in the South and West, scientists warned in a study published Monday.
The risk of exposure to extreme heat could be as much as six times higher for the average U.S. citizens by the year 2070, compared with levels experienced in the last century, researchers at the National Center for Atmospheric Research and the City University of New York found. The projected change carries significant implications for Americans’ health, as extreme heat kills more people than any other weather-related event, the study’s authors report in the journal Nature Climate Change.
“Both population change and climate change matter,” said co-author Brian O’Neill, an NCAR scientist and expert on modeling impacts of climate change. “If you want to know how heat waves will affect health in the future, you have to consider both.” [Continue reading…]
