CBS News: Zack Labe, a postdoc in the Department of Atmospheric Science at Colorado State University and an expert on Arctic climate, told CBS News that while he is concerned by the recent heat, he is more unnerved by its staying power. “I am still much more alarmed by the persistence of the record warmth — since December 2019, western Siberia temperatures have averaged nearly 9°F above average (1981-2010), which is quite astounding.”
