Canada's Record-Setting 2023 Fires Produced As Much CO2 As 10 "Normal" Fire Seasons

Canada’s “record-shattering” wildfires last year produced nearly as much greenhouse gas emissions in one season as would be expected over a decade of fires in normal circumstances, data has shown.

The fires, in Canada’s “wildest season ever”, were made at least three times more likely by the climate crisis, and produced about 2bn tonnes of CO2, about a quarter of the total global emissions from wildfires last year, according to data in the State of Wildfires report, published on Wednesday. The health impacts from last year’s fires will also continue to be felt for decades.

Carbon dioxide from wildfires is a growing source of greenhouse gas emissions globally, reaching about 8.6bn tonnes last year, considerably more than the 4.8bn annual emissions of the US from all sources. However, the net impact of fires is likely to be reduced by the regrowth of vegetation taking up carbon from the atmosphere.

Matthew Jones, a research fellow at the Tyndall Centre for Climate Change Research at the University of East Anglia, and lead author of the report, warned that damage from intensifying wildfires would continue to increase unless the world succeeded in bringing down greenhouse gas emissions. Wildfires not only kill people, wildlife and livestock, and devastate trees and other landscapes, but can cause widespread and dangerous air pollution. They are also an increasingly important contributor to the climate crisis, through their greenhouse gas emissions and destruction of carbon stored in vegetation and soil.
