Temperatures in the Barents Sea region are ‘off the scale’ and may affect extreme weather in the US and Europe
It was already known that the climate crisis was driving heating across the Arctic three times faster than the global average, but the new research shows the situation is even more extreme in places.Sea ice is good at reflecting sunlight but is melting away. This allows the darker ocean below to absorb more energy. Losing sea ice also means it no longer restricts the ability of warmer sea waters to heat up the Arctic air. The more ice is lost, the more heat accumulates, forming a feedback loop.
“The broader message is that the feedback of melting sea ice is even higher than previously shown,” he said. “This is an early warning for what’s happening in the rest of the Arctic if this melting continues, and what is most likely to happen in the next decades.” The world’s scientists said in April thatand other greenhouse gases are needed to tackle the climate emergency.
The result was a high-quality set of surface air temperature measurements from 1981 to 2020. The researchers concluded: “The regional warming rate for the Northern Barents Sea region is exceptional and corresponds to 2 to 2.5 times the Arctic warming averages and 5 to 7 times the global warming averages.”
