A source at the Arctic and Antarctic Research Institute announced that researchers have found “poles of global warming”, as they found in some regions that average annual warming is much higher than global indicators.
The source indicated in an interview with the Russian RIA Novosti news agency, that scientists from the Arctic and Antarctic Research Institute, the University of Petersburg and the Polar Geophysics Institute, in cooperation with the scientists of the Norwegian Meteorological Institute, conducted a comprehensive analysis of satellite data for the years 1981-2020 in the regions of Svalbard and the Francois Joseph Archipelago, They focused on near-surface air temperature, sea surface temperature and salinity, the speed of ice melt, and other indicators.
As a result, the researchers found the “global warming poles” – places where the temperature rises, as it became clear to them that the annual average temperature rise on the island of Karl XII, northeast of Svalbard, is equal to 2.7 degrees Celsius during 10 years (in autumn 4 degrees Celsius). The Russian island of Hesse, belonging to the Francois Joseph archipelago, came second with 2.2 degrees Celsius (in winter 3.8 degrees Celsius).
In general, it turned out that the areas of the north and east of the Barnes Sea are warming faster, as it was found that the rate of warming there was twice what was previously thought during 40 years, and intensified in the past twenty years (from 2001 to 2020). And that the average temperature rises in the winter, while it remains stable or rises slightly in the summer (from zero to 0.7 degrees Celsius within 10 years).
Scientists link the warming of the Arctic to a rise in sea surface temperature and a decrease in the volume of sea ice. In different parts of the Barents Sea, the size of the decrease ranges between 7 and 25 percent within 10 years. And compared to the eighties of the last century, the area of the ice cover decreased by 40 percent and is now equivalent to 330,000 square kilometers.
