Carbon emissions from Canadian forest fires continue to rise Experts warn of ‘dangerous cycle’
According to data from the Copernicus Atmospheric Monitoring Service, the European Union’s climate monitoring agency, as of the end of July, the cumulative carbon emissions from forest fires in Canada this year have reached 290 million tons, and because the current fires are still burning, this number will rise. Experts warn that the greenhouse gases emitted by forest fires will accelerate global warming and may create climate conditions that make forests more likely to burn, forming a vicious circle.
According to the report of the Copernicus Atmospheric Monitoring Service, the area burned by forest fires in Canada this year and the amount of carbon emissions generated have both broken historical records. In the first seven months of this year alone, the cumulative carbon emissions from forest fires in Canada have reached 290 million tons, more than double the record for Canada’s annual forest fire carbon emissions in previous years, accounting for more than 25% of current global emissions this year. According to relevant conversions, 290 million tons of carbon emissions are equivalent to more than 1 billion tons of carbon dioxide equivalent.
Judging from the data of previous years, the forest fire activity in Canada generally reaches its peak in July and August each year, but this year, the record has been set before July, showing that this year has become the worst forest fire in Canada since records began. The resulting carbon emissions will also continue to rise.
Kirsten Zickfield, a professor of climate science at Simon Fraser University in Canada, said that carbon dioxide emitted into the atmosphere will remain for a long time, which will accelerate global warming and have a long-term negative impact on the global climate.

Kirsten Zickerfield, professor of climate science at Simon Fraser University:This graph shows the percentage of carbon dioxide released into the atmosphere that remains over time, such as after 500 years, 30% to 70% of the carbon dioxide is still in the atmosphere; after 10,000 years, 30% of the carbon dioxide is still in the atmosphere remain in the atmosphere, suggesting that carbon retention is nearly permanent.
Zickfield warned that these carbon dioxide and other greenhouse gases could lead to a “dangerous cycle” that will further promote global climate change, leading to a higher probability of abnormal drought and sustained high temperature in the future, and these extreme weather will make the future The probability of large-scale forest fires is higher.
Kirsten Zickerfield, professor of climate science at Simon Fraser University:If we don’t manage to control greenhouse gas emissions, we will see the consequences of forest fires, and other natural disasters will become more frequent and affect more and more people, such as extreme heat, floods, etc.
