ARKHANGELSK, June 8. /TASS/. The peak of warming in the Russian Arctic is expected in 2030-35, Director of the Laverov Federal Research Center for Integrated Arctic Studies (the Urals Branch of the Russian Academy of Sciences) Ivan Bolotov told TASS. According to Professor Yury Shvartsman's model, the climate has 80-year cycles, and frosty winters may return to the Arctic regions after 2035.
"Professor Yury Shvartsman, founder of the European North geo-ecology school, worked a lot on climate models. In the early 1990s, he said we were on the ascending branch of a warm climate cycle, and it would be getting warmer and warmer in the north. That was supposed to continue until 2030-2035. He considered the 80-year climate cycle the main term. According to his concept, after 2030-35 will begin a descending branch of the cycle, a progressive cooling will begin, and severe winters will return to both the Arkhangelsk Region and the Russian North," the scientist said.
Shvartsman's models are based on previous cyclical climate, proved by the Arctic research that was actively conducted in the late 19th and in the early and mid-20th centuries. A noticeable warming of the Arctic Region in the 1930s and 1940s gave way to a cooling with a peak in the 1970s. "After the 1970s, again began the warming, and it was growing by leaps and bounds in the 1990s," he noted.
