The fires came as record heat returned to part of the western United States over the weekend, fueled by the climate crisis. Las Vegas tied an all-time record high of 117 degrees Fahrenheit; Palm Springs, California, hit a record 120 degrees; and the overnight low in Phoenix on Friday was 93 degrees. Maricopa County officials have logged over 100 suspected heat-related deaths so far this year. Death Valley hit 130 degrees on Sunday for just the fifth time ever — tied for the highest temperature ever reliably recorded on Earth. And in the Arctic Circle, the town of Banak in northern Norway reached 94 degrees Fahrenheit last week — hotter than the highest temperature recorded in Miami, Florida, this year.
