U.S. Heatwave ‘Virtually Impossible’ Without Climate Change, Scientists Say
An international group of 27 climate scientists have concluded that the recent heat wave in the Pacific Northwest was “virtually impossible without human-caused climate change.”
National Weather Service reports show that in late June Seattle, Wash., reached all-time high temperature of 108 degrees F, while Portland, Ore. hit 116 F, also an all-time high.
The heat landed far outside the range of historically recorded temperatures, according to the scientists in a report released by World Weather Attribution. The scientists also note that the heatwave occurred a full month before the climatologically warmest part of the year, “making them particularly exceptional.”
