Record-Breaking Heat Wave In Alaska

A massive dome of high pressure, a so-called “heat dome,” sat over Alaska this past week, bringing all-time record temperatures just a few weeks after parts of the state had a record cold start to spring, reports Andrew Freedman at Climate Central. In some cases, towns in Alaska were warmer than most locations in the lower 48 states that same day.  In fact, it was warmer in Talkeetna, which is about 110 miles north of Anchorage, than it was in Miami, said the National Weather Service. Extreme heat was also felt across the interior of Alaska, where hot temperatures are expected to continue 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, raises the risk of wildfires across parts of Alaska. Alaska is one of the fastest-warming states in the US, 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 contend with large wildfires, melting permafrost, and reduced sea ice, among other climate-related challenges.


Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
