It should also be noted that there is "pretty much no relationship" between November snowfall and December to February snowfall, Brettschneider tweeted. The Arctic is not as cold as it used to be — the region is warming faster than any other — and studies suggest that this warming is weakening the jet stream, which ordinarily acts like a giant lasso, corralling cold air around the pole. And as with any single weather event, it’s difficult to directly attribute the influence of climate change to a particular cold spell. According to research by Dr. Brian Brettschneider, climatologist at the University of Alaska Fairbanks, the answer is yes. Earth at the beginning of each season.
