Cataclysms of the outgoing year

2020 claims to be one of the three hottest years on record. The World Meteorological Organization has already published the corresponding assessment. Ocean temperatures are at an all-time high. Extreme heat waves, wildfires and floods, as well as a record Atlantic hurricane season, have affected millions of people.

“The most noticeable warming was observed in North Asia, especially in the Siberian Arctic. The temperature was higher than the average by more than 5 degrees. This is an average annual temperature, which means a lot. And the culmination of the Siberian heat came at the end of June,” said Vladimir Kattsov , Director of the Main Geophysical Observatory. A.I. Voeikova.

At one of the Russian poles of cold, in Verkhoyansk, on June 20, the temperature reached 38 degrees. This figure became the highest ever recorded in the history of the Arctic Circle. The extreme heat triggered the most active bushfire season in 18 years. The Arctic region generally reacts most sharply to global climate change. The area of ​​ice in the Arctic in July 2020 was the smallest on record. The Laptev Sea did not freeze until October.

“On average in the Arctic, the temperature for the period of instrumental observations since the beginning of the 20th century has increased by about three degrees. This is almost three times more than the average global temperature,” said Vladimir Semenov, Deputy Director of the A.M. Obukhov Institute of Atmospheric Physics RAS, Head of the Laboratory of Climatology, Institute of Geography, RAS.

Overheating of the Arctic leads to disturbances in the circulation of the atmosphere, as a result of which the so-called blocking anticyclones arise over different regions of the planet. One of these foci caused an abnormally warm autumn in the central regions of European Russia. In Moscow, the Indian summer dragged on almost until December. Even in November, the buds on the trees swelled and flowers bloomed.

However, prolonged heat waves and lack of precipitation can be regarded as a pleasant bonus of global warming far from everywhere. Thus, in Crimea, a lack of rainfall and an abnormally high temperature led to the worst drought in 150 years. Several rivers dry up on the peninsula, including those feeding the reservoirs. It was necessary to introduce restrictions on the supply of water to the residential sector. Against the background of a record drought, a large-scale campaign was launched in the republic to develop new sources of water supply.

All these incidents in Russia and the world once again indicate rapid climatic changes.
