Canadian wildfires driven by climate change are pushing dangerous smoke across the U.S. Northeast and Midwest — that part is verified by major outlets. The author's broader point — that global climate inaction caused this and the U.S. bears responsibility — is scientifically grounded, though attributing the fires entirely to 'American-led inaction' oversimplifies a genuinely global problem. What's missing: the author doesn't acknowledge that Canada itself has increased carbon emissions and faces its own climate adaptation challenges, or that wildfire severity is affected by local forest management practices alongside global warming.
