A source from the Arctic and Antarctic Research Institute announced that climate changes are taking place in the Arctic, where average annual warming in some parts is higher than global indicators.
In an interview with Russian RIA Novosti news agency, the source said that scientists from the Arctic and Antarctic Research Institute, Petersburg University and Polar Geophysics Institute conducted a comprehensive analysis in collaboration with scientists from the Norwegian Meteorological Institute. Satellite data for the years 1981-2020 in the Svalbard and Francois Joseph Archipelago regions are focused on near-surface air temperature, sea surface temperature and salinity, ice melting speed, and other indicators .
As a result, the researchers found the “global warming poles”, areas where temperatures rise while the average annual temperature rise on the island of Karl XII, northeast of Svalbard, turns out to be equal to 2.7 degrees Celsius. For 10 years (4 degrees Celsius in the fall), the Russian island of Hesse, belonging to the Francois Joseph archipelago, came in second with 2.2 degrees Celsius (3.8 degrees Celsius in the winter).
In general, the northern and eastern parts of the Barnes Sea have become faster, as the rate of warming there has been found to be twice than thought in 40 years and has intensified over the past two decades (from 2001 to 2020). And while the average temperature rises in winter, it remains constant or slightly rising in summer (from zero to 0.7 degrees Celsius in 10 years).
Scientists attribute Arctic warming to rising sea surface temperatures and decreasing the amount of sea ice. In different regions of the Barents Sea, the size of the decline over 10 years varies between 7 and 25 percent. And compared to the 1980s of the last century, the area of the ice cover has dropped by 40 percent and is now equivalent to 330,000 square kilometers.
