Is the rapid melting of the Arctic paying us back for our greenhouse gas emissions by messing with the jet stream- which carries weather through the northern hemisphere? And could that, in turn, explain recent breakouts of extremes all around the northern half of the world- including recent snowfall in the east coast?… That’s what Rutgers University’s Jennifer Francis has argued in a series of papers going back to 2012- but there has been quite a lot of criticism. Several distinguished climate researchers even wrote to Science magazine in early 2014 contesting the notion, saying that "we we do not view the theoretical arguments underlying it as compelling."… And yet stubbornly, more published research keeps appearing and seeming to add support to the idea that the warming Arctic is changing the jet stream. That statement comes with an exclamation point on Thursday in particular, with a new paper out in Science that confirms many of Francis’s ideas and applies them not just to extreme winter weather but, in some ways even more troubling, to extremes of summer heat.
