evidence: Did climate change cause Canada's wildfires? Isabella Kaminski digs into the science on the role climate change and other factors play in wildfires. A spate of serious wildfires across Canada have become a global story in recent weeks, accompanied by photos of murky orange-hued landscapes. [...] Researchers have also long drawn attention to the way that Canadian forestry policies moved away from traditional and Indigenous practices of planned burning which safeguard valuable timber resources and people. Regular, controlled burning clears the forest understory and reduces the risk of larger fires spinning out of control, but this had been stopped in much of the country.
