“The Arctic 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 Tuesday 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.
While the whole planet is warming because of emissions of heat-trapping gases through burning of fossil fuels and other human activity, the Arctic is heating up more than twice as quickly as other regions. That warming has cascading effects elsewhere, raising sea levels, influencing ocean circulation and, scientists increasingly suggest, playing a role in extreme weather.”
