On Friday, June 20, the Siberian town of Verkhoyansk recorded an afternoon high temperature of 100.4 degrees. If the temperature holds up to scrutiny, it will go down as the hottest temperature recorded at any point north of the Arctic Circle. The region comprising Alaska, northwestern Canada, and much of eastern and northern Siberia have , in recent decades, been experiencing an accelerated climate warming relative to the rest of the world.
The past five summers have been particularly hot. Summer wildfires are off to a roaring start already this season following record heat during May. The European Union's Copernicus Climate Change Service has reported that the average temperature across eastern Siberia this May was 18 degrees higher than the May average from 1979 to 2019.
