In the Canadian province of Alberta, a massive wildfire exploded to 10 times its previous size on Thursday. The fire has forced all 88,000 residents to flee Fort McMurray, in the heart of Canada’s oil sands. About 16 percent of Canada’s crude oil production is offline as companies have cut operations. Over the course of one day, the fire spread from about 18,000 acres to more 210,000 acres—that’s an area about 10 times the size of Manhattan. Scientists have linked increased wildfires to climate change.
