A new study released this week finds that human-caused climate change increases the likelihood of the weather conditions associated with Canada’s major summer wildfires. Multiple outlets report that the research estimates climate change has doubled the odds of the “tinderbox” conditions that help drive large fire behavior, including hot, dry and otherwise conducive weather.
The findings are presented against a backdrop of political debate. U.S. President Donald Trump is cited as attributing the fires to mismanagement rather than climate change, and several reports note the study’s conclusions have fueled disagreement over the causes of the fires. Canadian outlets and international coverage describe how the wildfires produced widespread smoke that affected communities and attracted international attention.
Overall, the sources agree on the central point: the study links a portion of the increased wildfire risk to climate change by altering the probability of extreme fire-favoring conditions. The reporting does not dispute that other factors, including land and forest management, can play roles, but emphasizes that the study’s specific contribution concerns changes in atmospheric conditions driven by human activity.
