TOMSK, Jan 29 – RIA Tomsk. The average annual temperature in Siberia and the subarctic zone has increased by four degrees over the past half century, which led to the appearance of tornadoes in these territories, the press service of Tomsk State University (TSU) said referring to a study of the SecNet international network scientists, created under the auspices of TSU.
Earlier it was reported that the SecNet was created within the framework of the Trans-Siberian Scientific Way (TSSW) Institute of TSU as a tool for studying Siberia and the Arctic. Its structure includes leading institutes of Russia, Great Britain, Norway, the USA and Canada. The SecNet partners are Iteract II, University of the Arctic, American National Ecological Observatory Network (NEON, and Canadian mountain station network.
"SecNet experts have noted that the most dramatic changes in climate and ecosystems over the past half century have occurred in the Eurasian Arctic and Siberia: the average annual temperature has risen by almost four degrees. The research results are published in the highly rated journal Ambio (Q1), published by the Swedish Academy of Sciences", - is said in the message.
According to the SecNet scientific adviser Terry Callaghan, in Siberia and in the subarctic zone anthropogenic factors of environmental change (migration, industrialization and urbanization), as well as climatic changes in the natural environment (warming of the atmosphere, permafrost melting, shrinking glacier area) lead to an increase in uncharacteristic extreme events.
"Tundra fires, which were previously a rarity, became more frequent, tornadoes began to be recorded in Siberia, and there were more extremely dry and wet periods", - the professor is quoted in the report.

According to the authors of the article, the circumpolar North has become the "hottest" spot. So, the recording of the average annual temperature from the "Dikson Island" station shows that it was here where from 1968 to 2017 the average annual temperature increased by almost four degrees.
According to the SecNet experts, the increase in temperature and frequency of extreme events require scientists from around the world to conduct joint research. The results of this work will be important for developing a mechanism for the adaptation of mankind to global warming and survival under new conditions.

“Otherwise, people are expected to experience to experience socio-economic upheavals, hunger could be one of the first one. In the absence of an adaptation strategy, negative consequences will affect residents of prosperous territories that are not affected by fires, floods and other manifestations of the natural disaster, as large flows of migrants will go to these places", - is said in the message.
It is noted that the authors of the article were 16 scientists from leading research centers of Russia, Norway, the UK, Finland and other countries included in the SecNet network. In their joint work they presented the results collected during research at several dozen stations located in Siberia and the Arctic, including at the most remote bases, such as the "Willem Barents" station.
