USA - Millions More Americans Will Face Climate Disasters with Warming
The population exposed to one or more extreme weather events each year could more than double by mid-century
Roughly one-third of the U.S. population—or 118 million Americans—could feel one or more extreme weather events annually by 2050 if population and greenhouse gas emissions continue to rise, new research from the Energy Department’s Oak Ridge National Laboratory shows.
That more than doubles the 47 million Americans who currently experience extreme heat and cold, prolonged droughts, and intensifying floods. And it reflects the greater frequency of climate disasters nationwide, the researchers said.
The findings, published in Earth’s Future, a journal of the American Geophysical Union, are based on supercomputer simulations of county-level data from NOAA’s Climate Extremes Index, or CEI.
