Temperatures in Siberia have been well above average since the beginning of the year. A new temperature record for the Arctic of 38 ° C was recorded in the Russian city of Verkhoyansk on June 20, while global temperatures in Siberia were more than 5 ° C above the January average in June.
A new scientific study, published Wednesday, July 15, shows that the recent prolongation of heat in Siberia from January to June 2020 would have been nearly impossible without the influence of climate change. This study was conducted on the initiative of the World Weather Attribution (WWA) and brought together the European Meteorological Services and the Shirshov Institute of Oceanology.
Their analysis showed that prolonged heat such as that experienced in Siberia from January to June of this year would only occur once every 80,000 years without human-induced climate change. Climate change has increased the risk of prolonged heat by at least 600 times. This is one of the most compelling results of any attribution study conducted to date and is unambiguous evidence of the influence of man-made climate change on the planet.
Scientists noted that even in the current climate, prolonged heat was still unlikely. But without a rapid reduction in greenhouse gas emissions, they are likely to become frequent by the end of the century.
In previous studies, global weather attribution had linked climate change to extreme events, including wildfires in Australia in 2019 and 2020, heatwaves in Europe in 2018, and hit Texas in 2019.
