From Climate Central:
Mild weather has been the norm for the region month after month for awhile now. But while these stories have become an almost monthly fixture, make no mistake. It is extremely abnormal for the Arctic — or any other part of the world for that matter — to be repeatedly blitzed by temperatures this far above normal and the impacts are reshaping the region.
Incredibly mild air is surging into the Arctic again, cranking up the heat as melt season gets underway.
