In Siberia, June was record hot and in some places the average temperature was up to 10 degrees Celsius higher than usual, the BBC reported. According to the researchers, the heat contributed to wildfires in the area, causing up to 59 million tons of carbon dioxide to be released into the atmosphere.

The hot summer is not an unusual phenomenon in Arctic Siberia, but the last few months have been exceptionally warm.

Carlo Buontempo, director of the EU's climate change service Copernicus, considered the trend "worrying". According to Copernicus researchers, average temperatures in the area were 5 degrees higher than usual. This is more than a degree higher than in the previous record months of June 2018 and 2019.

Copernicus researcher Mark Parrington said in an interview with CNN that warm weather contributes to wildfires.

- Higher temperatures and drier soils provide ideal conditions for these fires to burn and continue for so long over such a large area.

In late June, in Siberia, north of the Arctic Circle, +38 degrees was measured, a new heat record. It was also 18 degrees higher than the average peak temperature in the region in June.

The record reading was measured in the city of Verkhoyansk.
