Polarization score: 3/5

Most outlets treat this as an environmental or public health story, but Politico's framing introduces a distinctly political angle by centering Trump's threats against Canada, which diverges sharply from the others. This political injection creates moderate polarization, though the majority of outlets remain relatively aligned in treating it as an environmental/health event.

The core difference is whether outlets frame the wildfire smoke as an environmental/health crisis or as a political story. Most outlets focus on air quality severity, geographic impact, and health risks, while Politico uniquely centers the story on Trump's threats toward Canada, transforming an environmental event into a political confrontation narrative.

⚠️ Coverage gap: None of the outlets in their headlines/intros substantively address the climate change context underlying the increasing severity and frequency of Canadian wildfires. Additionally, only Politico covers the political response (Trump's threats), meaning readers of the other outlets may miss the diplomatic dimension, while Politico readers may miss the health and environmental dimensions.
