Much of Siberia this year has witnessed unseasonably high temperatures—nearly twenty degrees Fahrenheit higher than normal the past couple of months.
The head of Russia’s weather service is blaming man-made climate change for these abnormal high temperatures.
“We had extremely anomalous weather” in June, Roman Vilfand told AFP, adding that “previous records were broken easily.”
“That is a fantastical degree,” Vilfand said.
The temperature reading is still being verified by the World Meteorological Organization, but if it holds, it will be the hottest temperature ever registered in the Arctic Circle.
The initial temperature reading was conducted by Pogoda i Klimat, a website that compiles Russian meteorological data.
Vilfand said the troubling trend of sunnier skies and hotter temperatures is being driven by changes in atmospheric circulation.
He pinpointed the more-frequent phenomenon of polar anticyclones, which increase the number of days with sunny skies. Without clouds to help block the sun’s rays, the ground is much warmer during the summer months in the Arctic.
Previously “meteorologists didn’t note fire hazardous situations in the polar regions often,” Vilfand said.
“It’s an astonishing situation. Anticyclones happen more and more often and you can never predict where they are going to occur. This is the most important problem of climate change and a result of climate change.”
Past studies have shown that the Arctic is warming twice as fast as the rest of the planet through a process known as Arctic amplification.
The average increase in temperature on the entire planet over the past forty years is 1.44 degrees Fahrenheit. In comparison, the Arctic has warmed by more than 3.5 degrees Fahrenheit during the same period.
Amid increasing ice melt in the region, this leads to seasonal snow cover that isn’t as white and naturally absorbs more sunlight—driving forward more warming, according to the National Oceanic and Atmospheric Administration.
The Arctic sea ice has lost 70% of its summer volume since the 1970s.
