Numerous cities across the United States are seeing record-breaking temperatures as a heatwave moves across the country, with another round of 100-plus-degree days expected later this week.
Cities in at least eight states hit record highs in the past week, and the National Weather Service (NWS) is predicting more extreme heat for the Pacific Northwest this weekend.
The Environmental Protection Agency has pointed to the intensity of heatwaves as a sign of climate change. And, as the heat blisters on, wildfires are igniting across Arizona, California, Colorado, Montana, Utah and Wyoming.
Cities in these eight states all experienced record highs in the past week.
Arizona
