A record-breaking 59,000 square miles have burned across Canada this year, forcing nearly 1 out of every 200 Canadians to evacuate their homes and smothering vast parts of North America in choking smoke.
New research shows some of those fires were likely made worse by climate change. During the early summer, the hot, dry, windy weather that whipped Quebec's fires into infernos was at least twice as likely, and 20% more intense, because of human-caused climate change, according to an analysis by the World Weather Attribution group, a research organization centered at Imperial College, London.
