Ecology: scalding heatwave covering Siberia is “almost impossible” without man-made activities

According to the new study, scalding heatwave, with temperatures soaring as high as 38 degrees Celsius, covering Siberia this summer has become a result of burning fuel, wildfires, thawing permafrost and other human activities. Many scientists also consider it to be the evidence of increasing extreme temperatures. A group of scientists on Wednesday stated that this would have been “almost impossible” without human-caused climate change, as reported by

A new study, which has not been peer reviewed yet, was carried out by an international team of scientists from the many countries: UK, Russia, France, the Netherlands, Germany and Switzerland. They leaped to a conclusion that the greenhouse effect multiplied Siberia’s possibility of heat by at least 600 times. 

The study has examined temperature data in the region within the period from January to June, and a day when the temperature reached a record 38 degrees Celsius in the town of Verkhoyansk, located on the Yana River in the Arctic Circle.

Lead author of the research and Senior Detection and Attribution scientist at the Met Office Andrew Ciavarella specified that this would have been ”almost impossible without human influence.”

“This research is further evidence of the extreme temperatures we can expect to see more frequently around the world in a warming global climate. Importantly, an increasing frequency of these extreme heat events can be moderated by reducing greenhouse gas emissions,” he pointed out.

In its work the team used 70 climate models, running thousands of complex simulations comparing current conditions to a world without man-made warming from the burning of coal, oil and gas.

They state that this summer extra heatwave trapping gases from burning fuel, along with widespread wildfires and the thawing of permafrost, which caused some major “oil-related disasters”, contributed to this year’s heatwave. All of these “oil disasters” are related to Norilsk Nickel (Nornickel), a Russian nickel and palladium mining and smelting company, being among the Russia’s most polluting companies. If based on the 2018 figures it releases approximately 1.67m tonnes of harmful sulphur dioxide every year into the air.
