The Arctic is heating up more than twice as quickly as other regions.

It continued its unwavering shift toward a new climate in 2020, as the effects of near-record warming surged across the region, shrinking ice and snow cover, and fueling extreme wildfires, scientists said in an annual assessment of the region.

Rick Thoman, a climate specialist at the University of Alaska and one of the editors of the assessment, said it “describes an Arctic region that continues along a path that is warmer, less frozen and biologically changed in ways that were scarcely imaginable even a generation ago.”

“Nearly everything in the Arctic, from ice and snow to human activity, is changing so quickly that there is no reason to think that in 30 years much of anything will be as it is today,” he said.

That warming has cascading effects elsewhere, raising sea levels, influencing ocean circulation and, scientists increasingly suggest, playing a role in extreme weather. This year the minimum extent of sea ice in the Arctic Ocean, reached at the end of the melt season in September, was the second-lowest in the satellite record, the scientists reported. On land, the huge Greenland ice sheet and glaciers in Alaska and elsewhere lost mass at above-average rates, although the rate in Greenland slowed from last year.
