From Climate Central:
Extreme heat was also felt across the interior of Alaska, where hot temperatures are expected to continue this week until the large high pressure area, or ridge in the jet stream, weakens and moves away. The heat, combined with low relative humidity and the chance for thunderstorms, is raising the risk of wildfires across parts of Alaska.
Alaska is one of the fastest-warming states in the U.S., largely because the nearby Arctic region is warming rapidly in response to manmade global warming and natural variability. In recent years, Alaska has had to content with large wildfires, melting permafrost, and reduced sea ice, among other climate-related challenges.
