Think winters are getting colder? Blame Arctic warming and, yes, the polar vortex

1 DAY AGO There is growing scientific support for one of the most provocative and counterintuitive ideas in climate change research, which holds that rapid Arctic warming may be causing colder winters across large swaths of the Northern Hemisphere.
A new study, to be published in the journal Bulletin of the American Meteorological Society, found that a weakening polar vortex, potentially set in motion by the rapidly warming and melting Arctic, has become more common during the past four decades. This results in colder winters across large regions of Europe and Russia, but also occasionally in the U.S. as well. The study is the first to show that changes in winds in the stratosphere substantially contributed to a mysterious winter cooling trend in northern Europe and Asia, including a region already known for being frigid: Siberia.
