Arctic warming much faster than expected

Compared to the global average, the Arctic is indeed warming faster than previously thought, according to a study published in the journal Communications Earth & Environment. The Arctic plays an important modulating role in the global climate system. But past reports have said that the polar regions are warming at an average rate two to three times faster than the rest of the world and are experiencing the most dramatic increases in global surface temperatures, a phenomenon known as the Arctic amplification effect. Scientists at the Finnish Meteorological Institute analyzed observations of the Arctic Circle from 1979 to 2021 and estimated that most of the Arctic Ocean warmed at a rate of 0.75°C per decade during this period, at least four times the global average. In the Eurasian part of the Arctic Ocean, adjacent to Svalbard and Novaya Zemlya, the warming rate is as high as 1.25°C per decade, already seven times faster than the rest of the world. The research team believes that the Arctic amplification effect will increase over time due to increased sea ice loss.
