In heat waves in Siberia blamed global climate change

Computer simulations showed that the wave of heat that swept Eastern Siberia in the first half of 2020, is a consequence of global climate change. According to the report of the International initiative group for the study of weather phenomena (World Weather Attribution), without anthropogenic climate impacts like heat waves in this region could not occur more than once in 80 thousand years. According to estimates of the authors of the study, global climate change has increased the chances of lasting heat at least 600 times.

Global climate change is characterized by more frequent occurrence of abnormally high temperatures and droughts in many continental regions of the globe. In June in the city of Verkhoyansk, which is located beyond the Arctic circle in the far North of Yakutia, has been registered the air temperature +38 degrees Celsius. The world meteorological organization saidthat this case may be a new temperature record for the Arctic, and the beginning of the test, which will allow you to install the appropriate new category in its Global archive of extreme weather and climate events.

The effects of heat waves in Siberia can be not only damages local ecosystems and urban areas, but also major changes in Earth’s climate: increasing temperatures will lead to melting of permafrost and reduction of power snow. At the end of June in Siberia already burned 1.15 million hectare of forest that was the cause of the emission of 56 million tons of carbon dioxide — more than the total annual emissions of Norway.

The international initiative group for the study of weather phenomena (World Weather Attribution) published a report with preliminary results of the analysis of heat waves 2020 in Siberia, in the drafting of which was attended by the staff of the meteorological services and scientists from then Federation, France, Germany, the Netherlands, Switzerland and the UK.
