From extreme melt events to an influx of beaver colonies in Alaska, and rain falling at the summit of Greenland for the first time on record, the Arctic region showed clear symptoms of an ailing planet over the past year.
A report published on Tuesday, which serves as an annual physical for the Arctic, found this vast and significant biome is changing profoundly. It continues to warm twice as fast as the rest of the Earth and is rapidly losing ice cover, transforming from a reliably-frozen landscape to a greener and browner one than it was just around a decade ago.
As temperatures at the summit rose above freezing for the third time in less than a decade, the warm air fueled an extreme rain event that dumped 7 billion tons of water on the ice sheet. A report published after that event found this was likely to happen more often. The Arctic is expected to experience more rain than snow some time between 2060 and 2070, marking a major transition in its precipitation patterns as the climate crisis jacks up temperatures in the region.
