Climate Change Made This Summer’s Canadian Wildfires Twice as Likely
Wildfires in the Canadian provinces of Ontario and the Northwest Territories have burned more than 3.9 million hectares this summer, prompted widespread evacuation orders, and created poor air quality for not only Canadians, but more than 120 million people across the midwestern and northeastern United States. The fires spread exceptionally quickly, stressing the resources of local response agencies. About 700 fires are still active across Canada.
According to a new analysis, human-induced climate change and its contribution to fire conditions across Canada made these fires twice as likely to occur. The report is from World Weather Attribution, an international climate science partnership.
