Since early June, the Copernicus Atmosphere Monitoring Service (CAMS), which provides data on atmospheric composition and emissions, has tracked more than 100 intense forest fires on the Arctic Circle.
Pierre Markuse, an expert in satellite photography, said the region has seen fires in the past, but never so many.
Arctic temperatures are rising faster than the global average, providing the right conditions for the spread of forest fires, according to Mark Parrington, a senior scientist at CAMS.
"The number and intensity of wildfires at the Arctic Circle is unusual and unprecedented," Parrington told CNN.
"They are worrying as they occur in a very remote part of the world and in an environment that many people consider immaculate," he said.
The average June temperature in Siberia, where the fires rage, was almost 10 degrees above the long-term average between 1981 and 2010, Dr. Claudia Volosciuk, scientist at the World Meteorological Organization (WMO) to CNN.
Parrington said there are more forest fires due to local heat waves in Siberia, Canada and Alaska.
The fires themselves contribute to the climate crisis by releasing carbon dioxide into the atmosphere.
They emitted an estimated 100 megatons of carbon dioxide (CO2) into the atmosphere between June 1 and July 21, which is almost equal to the equivalent of Belgian carbon emissions in 2017, according to CAMS.
According to Volosciuk, forest fires also exacerbate global warming by releasing pollutants into the atmosphere.
"When smoke particles land on snow and ice, [they] the ice absorbs the sunlight that would otherwise reflect it, thereby speeding up warming in the Arctic," she said.
