Climate change contributed to big Canada fires, study says as Trump blames mismanagement

A recent study suggests that climate change played a significant role in the extreme and massive wildfires in Canada during the summer. The research, conducted by World Weather Attribution, found that the frequency of the tinderbox weather conditions in the Northwest Territories and northwestern Ontario was twice as likely due to global warming.

This doubling of frequency occurred when the researchers compared current conditions to a world without the 2.5 degrees of warming that has occurred since the industrial age. The study, while not yet peer-reviewed, looked at the weather conditions connected to large wildfires and the Canadian index for those conditions.

Fire and climate scientists, reacting to the study, criticized President Donald Trump for blaming Canada for poor fire management. They emphasized that the United States has historically contributed significantly more to heat-trapping gas emissions than Canada, through the burning of coal, oil, and gas. The researchers noted that while people start about half of Canada's wildfires, lightning-caused fires are responsible for over 90% of the land area burned in the country.

According to the study, the fire weather conditions in Canada that led to the intense and rapidly spreading wildfires are now occurring every six years or so, as opposed to once in a lifetime in a pre-industrial climate. The findings, which have been reviewed by Science X, point to the importance of addressing climate change as a crucial step in mitigating the frequency and intensity of such wildfires.
