Two studies published recently in the journal Science link the recent fires to climate change, meaning they’re likely to become more common unless rising temperatures can be curbed.
That was driven largely by earlier snow melts, which led to more plant growth in the area. A heatwave in 2020 then dried the vegetation out, making it perfect wildfire fuel.
A second study determined the conditions in the Arctic in 2020 were caused partially by a strong wind known as the Arctic front jet. The jet stream offshoot only occasionally hits the area, but has become three times as common in the last 40 years.
