The warming speed is as high as 1.25 ° C every ten years, and the local warming speed of the Arctic reaches 7 times other places in the world

A climate change paper published by the British "Communication · Earth and the Environment" magazine on the 11th states that the North Pole Warming speed is indeed faster than before compared with the global average. Polar acceleration warming indicates that the region's sensitivity to global warming is higher than the current assessment.

The Arctic plays an important modulation role in the global climate system. However, the past reports stated that the average heating rate of polarity is 2-3 times that of other places around the world, and it is the area where the temperature of the global surface increases is the most severe. This phenomenon is called the Arctic amplifier effect. At present, countries around the world and meteorological organizations have paid great attention to the changes in the Arctic temperature.

Finnish Institute of Meteorological Research Institute, Mika Landanin and his colleagues, analyzed the observation data from the Arctic Circle from 1979 to 2021. It is estimated that most of the Arctic Ocean during this period warmed at a rate of 0.75 ° C every ten years, at least It is 4 times the global average. In the Eurasian part of the Arctic Ocean, near Swarba and Xindi Island, the warming speed is as high as 1.25 ° C every ten years, and it has been 7 times other parts of the world. The research team believes that due to the increase in sea ice loss, the Arctic amplification effect will intensify with time.

Researchers said that climate model forecasts may generally underestimate the Arctic amplifier effects between 1979 and 2021. They call for more detail to study the mechanism of the Arctic amplification effect and their performance in the climate model.
