The rapid warming of the Arctic, a definitive sign of climate change, is occurring even faster than previously described, researchers in Finland said Thursday.
Over the past four decades the region has been heating up four times faster than the global average, not the two to three times that has commonly been reported. And some parts of the region, notably the Barents Sea north of Norway and Russia, are warming up to seven times faster, they said.
One result of rapid Arctic warming is faster melting of the Greenland ice sheet, which adds to sea-level rise. But the impacts extend far beyond the Arctic, reaching down to influence weather like extreme rainfall and heat waves in North America and elsewhere. By altering the temperature difference between the North Pole and the Equator, the warming Arctic appears to have affected storm tracks and wind speed in North America.
