How much did wildfires increase Arctic carbon dioxide emissions?

Question

Accepted Answer

Wildfires Significantly Increased Arctic Carbon Dioxide Emissions Last Year

Last year, unprecedented wildfires in the Arctic released approximately 35 per cent more carbon dioxide compared to 2019. This surge in emissions is particularly concerning as 2019 itself recorded the highest emissions from Russian fires since 2003, indicating a worsening trend in Arctic wildfire activity and its impact on global greenhouse gas levels.
Arctic Wildfire Emissions Exceeded Previous Records

The scale of carbon dioxide released by Arctic wildfires last year marked a substantial increase. These fires contributed about 35 per cent more CO2 than was emitted in 2019. This figure highlights an escalating problem, as 2019 had already seen the highest emissions from Russian fires recorded since 2003.
Thawing Permafrost Adds to Greenhouse Gas Release

Beyond wildfires, the warming Arctic tundra and thawing permafrost are releasing trapped greenhouse gases, primarily carbon dioxide and methane. As the permafrost thaws more deeply, the volume of these gases released into the atmosphere increases. This process, combined with the impact of wildfires, poses a significant challenge to efforts aimed at curbing climate change.
Emissions from Permafrost Thaw May Be Underestimated

Current global emissions agreements may not fully account for the greenhouse gases released from the Arctic. Estimates for emissions from the gradual thaw of permafrost, which covers a quarter of the Northern Hemisphere, do not incorporate the impact of recent wildfires and abrupt thawing events. This omission suggests that the overall emissions figures used in global predictions might be too low.
Potential for Increased Emissions by Century's End

Researchers estimate that the combined effect of fires and abrupt thawing events in permafrost regions could lead to an increase in carbon emissions by up to 40 per cent by the end of this century. Such an increase would significantly exceed the global emissions budget, jeopardising the goal of limiting average global temperature rise to 1.5 degrees Celsius above pre-industrial levels, as outlined by the 2015 Paris Agreement.
