A dynamic change to winter, due to global warming, would occur if the warming of the planet overall alters patterns of atmospheric circulation in some way. And this is precisely what some researchers have proposed as the reason why we’re getting these crazy winters… Jennifer Francis, a climate scientist at Rutgers University who focuses on changes to the Arctic, is the best known researcher to make this argument. She believes that the decline of Arctic sea ice is weakening the northern hemisphere jet stream, which brings us our weather. A weaker jet stream, she continues, is more likely to get "stuck" in persistent weather patterns, leading to weather extremes of varying types (whether snow, rain, or lack of rain)… Last week, Francis said that when it comes to this winter and also the last one for the East Coast, "Mother Nature certainly has been giving us lots to talk about." She noted that while her views are certainly not accepted by all researchers, "there’s been so much new work that’s come out, just in the last six months even, that, it’s getting harder for people to say, ‘oh there’s nothing to this hypothesis.’"
