President Trump and other U.S. Republicans are attributing recent wildfire smoke affecting parts of the United States to conditions in Canada, arguing Canada is not adequately maintaining forests and brush. In reporting from The Hill, scientists and experts interviewed in both the U.S. and Canada say the underlying drivers are broader and are consistent with climate change, rather than solely forest management failures. The experts contend that warming temperatures and shifting weather patterns increase the likelihood and intensity of wildfires, which then generate smoke that can move across the border.

While the political debate centers on accountability and whether Canadian land management practices are sufficient, the scientific view presented in the articles emphasizes environmental factors linked to climate change. The reports describe both the immediate issue—smoke that has “choked” portions of the U.S. in recent days—and the longer-term explanation offered by experts, who frame wildfire risk as increasingly shaped by climate conditions rather than a single policy or maintenance issue.
