Siberia has recorded its warmest June, says Copernicus’ atmospheric surveillance service

Siberia is one of the coldest areas on Earth, but is currently battling strong fires and record high temperatures.

Surface carbon dioxide emissions for June were the highest in 18 years of CAMS data, erasing the record of 53 megatons set in June 2019.

“Higher temperatures and drier surface conditions provide ideal conditions for these fires to burn and last so long in such a large area,” said CAMS senior scientist Mark Parrington.

“We have seen very similar patterns in fire activities and soil moisture anomalies across the region in our fire monitoring activities in recent years.”

Siberia also experienced its warmest June amid unprecedented heat, according to the Copernicus Climate Change Service (C3S), a program affiliated with the European Commission.

Temperatures in the region were up to 10 degrees Celsius (18 degrees Fahrenheit) in June above average.

In Siberia, large temperature changes occur from month to month and from year to year. But temperatures in the region have remained well above the 2019 average, which is unusual.

June temperatures across Siberia were more than five degrees Celsius (nine degrees Fahrenheit) higher than average and more than one degree Celsius (1.8 degrees Fahrenheit) higher than the same month in 2018 and 2019, the two previous warmest June.

CS3 estimated that eastern Siberia hit a maximum hourly Arctic temperature of 37 degrees Celsius (100.4 degrees Fahrenheit) on June 20. That’s a new high for the Arctic, as one to two degrees Celsius is warmer than previous records set in Alaska in 1969 and eastern Siberia in 1973.
The Siberian heat wave has also contributed to falling sea ice levels, especially in the Arctic Ocean, he said. National Snow and Ice Data Center of the United States.

But not all parts of the region are affected. Western Siberia recorded mostly below-average temperatures last month.

The entire planet recorded record temperatures last month, linking to 2019 for the warmest June at a record level, of 0.53 degrees Celsius (0.95 degrees Celsius) above the 1981-2010 average.

In 2020, Copernicus found that four of the first six months of the year were the warmest globally or related to previous record temperatures. The exceptions were February and March 2020, which were the second warmest recorded in the world.

“Discovering what caused these record temperatures is not straightforward as many contributing factors interact. Siberia and the Arctic Circle generally have large fluctuations from year to year and have experienced other relatively warm June before,” said C3S director Carlo Buontempo. “What’s worrying is that the Arctic is warming faster than the rest of the world.”

“The experience of western Siberia warmer than average temperatures so long during winter and spring are unusual, and the extremely high temperatures in Arctic Siberia that occurred in June 2020 are equally a cause for concern, ”Buontempo said.

The Arctic is warming twice as fast as the rest of the planet through a process known as Arctic reinforcement.

Arctic ice melting has accelerated, leading to seasonal snow cover that is not as white and absorbs more sunlight, leading to more warming, according to the National Oceanic and Atmospheric Administration (NOAA).

Melting may already have dramatic consequences. A catastrophic oil spill in the settlement last month Siberian city of Norlisk, resulting in the spillage of 20,000 tons of fuel into the river, to reinforce permafrost in the Arctic city.

CS3 researchers believe large-scale wind patterns in Siberia, low snow cover and surface soil moisture may have led to milder temperatures this spring.
