Data showed that the wildfires that occurred last year shattered all records in Canada, producing an amount of greenhouse gas emissions equivalent to 10 years of emissions from wildfires under normal conditions.

The fires have become the most brutal ever.

According to the British newspaper "The Guardian", the fires have become the most brutal ever in Canada, producing around 2 billion tons of carbon dioxide, which is about a quarter of the total global emissions from wildfires last year, according to data from the wildfire status report published on Wednesday.

The health impacts from last year's fires will be felt for decades, as the carbon dioxide produced by wildfires represents a growing source of greenhouse gas emissions worldwide, reaching about 8.6 billion tons last year, which is significantly more than the annual emissions of 4.8 billion tons from all sources in the United States.

The net impact of the fires is likely to diminish through the regrowth of plants that absorb carbon from the atmosphere.

Warnings of damage caused by forest fires.

Matthew Jones, a researcher at the Tyndall Centre for Climate Change Research at the University of East Anglia, warned that the damage caused by increasing wildfires will continue to escalate unless the world succeeds in reducing greenhouse gas emissions. He noted that wildfires not only kill people and wildlife and livestock but also destroy trees and other landscapes, and may lead to widespread and dangerous air pollution, increasingly contributing to the climate crisis through greenhouse gas emissions and the destruction of stored carbon in plants and soil.

The area of wildfires in Canada, which has burned six times the annual average area, was the worst of last year's fires.
