Wildfires that have raged in the Arctic Circle since early spring led to a record spike in pollution from the infernos last month. Arctic fires emitted 16.3 million metric tons of carbon — or about 60 million metric tons of carbon dioxide — in June. That’s the highest since at least 2003 and almost nine times more than the same month in 2018, according to data from Europe’s Copernicus Atmosphere Monitoring Service. The previous June record was registered last year, when fires were the worst on record.

“The June 2020 map shows that the fire activity has been further to the east in the Siberian Arctic than in 2019, with more widespread fires in the non-Arctic parts of eastern Siberia,” CAMS senior scientist Mark Parrington said by email. “It is very surprising how similar the daily trend in the fire activity has been compared to 2019, especially as it is so unusual to all the other years of data that we have.”

This year some parts of the Arctic registered temperatures as much as 16 degrees Celsius (29 Fahrenheit) higher than usual in May and the town of Verkhoyansk in Siberia hit 38 degrees Celsius (100.4 Fahrenheit) last month. The fire season, which usually starts in early May and picks up at the beginning of June started earlier, with satellites registering wildfires as soon as March.
