So some respected researchers, publishing in scientific literature, do think that climate change is giving us these insane winters — but others remain skeptical. Like Elizabeth Barnes, an atmospheric scientist at Colorado State University. “Natural variability is very large, and the Arctic is not acting in isolation in terms of its influence on mid latitude weather,” Barnes told me. “To date, I can’t think of a study that shows that the Arctic is more important on influencing mid latitude weather than these other factors, like tropical warming.”
