Wildfires have caused nearly a quarter of all permafrost thaw—2,000 square kilometres—in Western Canada’s boreal peatlands over the past 30 years, according to a new University of Alberta study.
“Wildfire is a very important force on the landscape, and what we see here is that it continues to have impacts long after the burning is done,” said Carolyn Gibson, who conducted the research as part of her master’s degree studies in the Faculty of Agricultural, Life & Environmental Sciences.
