A Warmer Arctic Does NOT Cause Mid-Latitude Cold Snaps
February 21st 2021
Activist climate scientists of the Potsdam Climate Institute (PIK) and others have been claiming for years that a warming Arctic disturbs the jet stream, weakening the polar vortex which results in cold Arctic air dipping into the middle latitudes. Gullible media outlets have been repeating this false narrative to blame cold snaps on CO2 emissions. A new paper in Nature refutes the narrative. The paper says “But predictions of a more negative Arctic Oscillation, wavier jet stream, colder winters in mid-latitudes or, more specifically, in Eurasia, and more frequent and/or widespread cold extremes have not become reality.” The short term jet stream waviness that fuels the speculation of Arctic influences on mid-latitude cold snaps have not continued. The daily cold temperatures had been warming more than daily high temperatures which is beneficial to people and animals. The authors wrote “We argue that updated observational and reanalysis records [show] that the Arctic influence on mid-latitudes is small compared to other aspects of climate variability”. Pierre Gosselin discusses the story and says “The claim a warm Arctic is behind the brutally cold winter conditions at the mid latitudes is shown by a Nature study to be scientifically baseless. … But don’t expect the media to concede they’ve been duped any time soon.”
