LONDON (AP) — A book about a fire that ravaged a Canadian city and has been called a portent of climate chaos won Britain’s leading nonfiction book prize on Thursday. John Vaillant’s “Fire Weather: A True Story from a Hotter World” was awarded the 50,000 pound ($62,000) Baillie Gifford Prize at a ceremony in London. The chair of the judging panel, Frederick Studemann, said the book tells “a terrifying story,” reading “almost like a thriller” with a “deep science backdrop.” He called “Fire Weather,” which was also a U.S. National Book Award finalist, “an extraordinary and elegantly rendered account of a terrifying climate disaster that engulfed a community and industry, underscoring our toxic relationship with fossil fuels.” Vaillant, based in British Columbia, recounts how a huge wildfire engulfed the oil city of Fort McMurray in 2016.
