Climate change may be contributing to thousands more wildfire smoke-related deaths every year than in previous decades, a new study suggests. …The international study published Monday is one of the most rigorous yet in determining just how much climate change can be linked to wildfire smoke deaths around the world, said Sian Kou-Giesbrecht, an assistant professor at Dalhousie University. “What stands out to me is that this proportion is increasing just so much,” she said. The study estimates, using mathematical modeling, that about 12,566 annual wildfire smoke-related deaths in the 2010s were linked to climate change, up from about 669 in the 1960s. …The same research group is behind another study published in the same journal Monday that suggests climate change increased the global area burned by wildfire by about 16% from 2003 to 2019. …Kou-Giesbrecht said Monday’s study did not find that climate change had a major influence on the number of smoke-related deaths from Canada’s boreal wildfires.
