There’s more to the recent dramatic and alarming thawing of the Arctic region than can be explained by man-made global warming alone, a new study found.

Nature is pushing the Arctic to the edge, too.

But that energy transfer, which comes with storms that head north because of ocean currents, is not acting alone either, scientists say.

Another upcoming study concludes that the combination of both that natural energy transfer increase and man-made global warming serve as a one-two punch that is pushing the Arctic over the edge.
