Roy Spencer, meteorologist. While 2020 will be at or near record-warmth globally, this is not something we should be particularly alarmed about. The recent claim of the first 100 deg. F temperature reading above the Arctic Circle in Siberia is incorrect; it was 100 deg. F in Ft. Yukon, Alaska way back in 1915. The town in Siberia measuring 100 deg. F (Verkhoyansk) is notable for its exceedingly cold winters and hot summers, holding the Guinness World Record for the largest observed seasonal temperature swing: an astonishing 189 deg. F.
