China News Service, Beijing, August 13 (Reporter Sun Zifa) A climate change research paper recently published online by Springer Nature's professional academic journal "Communications - Earth and Environment" said, Compared to the global average, the Arctic is warming faster than previously thought. In the last 40 years, the rate of warming has been 0.75°C per decade, which is at least four times the global average.
Accelerating polar warming suggests the Arctic is more sensitive to global warming than current assessments suggest, the paper said. Past studies have reported that the polar regions are warming at an average rate two to three times that of the rest of the world, a phenomenon known as Arctic amplification.
Corresponding author of the paper , Mika Rantanen (Mika Rantanen) of the Finnish Meteorological Institute and colleagues analyzed Arctic Circle observation data from 1979 to 2021 and estimated that during this period most of the Arctic Ocean moved at a rate of every 10 The annual warming rate is 0.75°C, which is at least four times the global average. In the Eurasian part of the Arctic Ocean, adjacent to Svalbard and Novaya Zemlya, warming rates are as high as 1.25°C per decade, seven times faster than elsewhere in the world. They argue that Arctic amplification will increase over time due to increased sea ice loss.
The authors of the paper pointed out that climate model predictions may generally underestimate the Arctic amplification effect between 1979 and 2021, and they called for a more detailed study of the mechanisms of Arctic amplification effects and their performance in climate models. (End)
