The Arctic Circle spans Alaska. Local residents wear wool jackets and knitted hats in summer. This year, they have to wear sunscreen and umbrellas.
Some meteorologists believe that Alaska is unusually hot this summer. On the one hand, it is affected by the high-pressure ridge and on the other hand, it is related to climate change.
[record high temperature]
The Associated Press reported on the 5th that the temperature in Anchorage and other cities in central and southern Alaska was higher than that in the same period in previous years for five consecutive weeks. The temperature in Anchorage broke a 50 year record on the 4th.
The National Weather Service released a news on social media 'twitter' on the evening of the 4th. At 5 p.m. that day, the temperature at Anchorage International Airport was 32 degrees Celsius, a record high.

[increase in extreme weather]
Bill middot, meteorologist at the National Weather Service; Ludwig told the Anchorage Daily News that the "huge ridge of high pressure over Alaska" led to abnormal high temperatures.
Rick middot, a climate expert at the Alaskan Center for climate assessment and policy at the University of Alaska; According to Thoman, this round of high temperature not only has weather factors, but also takes climate change and global warming as the background. The rising sea temperature has an impact on the hot weather in Alaska. " This extreme weather event is more and more likely to occur in the future. "
He said that the rate of climate warming in Alaska is twice the average rate of global warming. " From 1901 to 2016, the average temperature in the United States increased by 1 ° C & hellip& hellip; Alaska rises 2.6 degrees Celsius. "
[inconvenient life]
The abnormal high temperature makes Alaska residents feel a lot of inconvenience. The hot weather experienced by Alaska in recent years has driven the melting of sea ice, which in turn has affected the community economy and wildlife survival.
The permafrost covering 85% of Alaska began to melt, affecting the foundation of buildings and wildlife habitat; In the past, vehicles could pass on some frozen rivers in winter, but in recent years, the ice was not hard enough due to high temperature, so it was impossible to drive safely; Crab fishing is affected because the sea ice that can be used as a civilian operation platform for fishing is not thick enough or does not exist at all; Due to the melting of some solid ice in the original competition venue, the well-known "aditarod dog sled race" in Alaska has to be held in another place this year; Due to the reduction of solid ice area, seal breeding may be affected this summer & hellip& hellip; (Rhododendron) (special feature of Xinhua News Agency)
