The effects of climate change
Climate change has plunged the Western U.S. into its worst drought in two decades. And a record-breaking heat wave only made things worse. In Arizona and Nevada, it’s been so hot that doctors warned people they could get third-degree burns from the asphalt. Wildfires raged in Montana and Utah. Power grids in Texas strained as officials asked residents to limit appliance use to avoid blackouts. The levels in Lake Mead, which supplies water for millions of people, are at their lowest since the 1930s.
