Arctic climate change may not be making winter jet stream weird after all?New research is pouring cold water on once-hot theory???Jet stream visualization. (NASA)?By Bob Henson?July 31 at 09:00 ET?An influential, highly publicized theory — that a warming Arctic is causing more intense winter outbreaks of cold and snow in midlatitudes — is hitting resistance from an ongoing sequence of studies, including the most comprehensive polar modeling to date.?The idea, first put forth in a 2012 paper by Jennifer Francis, now at the Woodwell Climate Research Center, and Stephen Vavrus, at the University of Wisconsin at Madison, is that two well-established trends — Arctic amplification (intensified global warming at higher latitudes) and depleted sea ice — can force the polar jet stream to dip farther south, thus causing more intense bouts of winter weather than might have otherwise occurred.

With mountains of research pointing to so many dire consequences of human-caused climate change — some of them already taking shape, such as the ominous growth of “hot droughts” in the U.S. Southwest — it’s easy to see how winter storms and cold blasts could be accepted as just another negative outcome, albeit a freakish one.?“The generalization that climate change makes extreme weather worse causes people to assume it makes all extreme weather worse,” said Texas state climatologist John Nielsen-Gammon. He’s now analyzing the extreme cold and snow that paralyzed his state in February. No studies have yet tried to directly attribute any or all of the Texas event to climate change.
