Early summer 2021 brought record highs to the normally temperate northwestern US and southwestern Canada. Portland, Oregon reported a high of 116 degrees Fahrenheit. A region in Washington’s Pacific Coast reported a temperature of 110 degrees, four degrees higher than the all-time high in Las Vegas. Climate scientists report global temperatures are now higher than they were in the late 1800s.
