President Trump threatens new tariffs on Canada as massive wildfires create a thick blanket of smoke across North America.
The administration announced that President Trump is threatening to impose new tariffs on Canada to offset the "incalculable" costs of smoke damage caused by hundreds of wildfires. The smoke, generated by intense blazes across Canada and the northern United States, has created some of the worst air quality globally, affecting major cities including New York, Chicago, and Detroit. The fires are fueled by a combination of sustained hot weather, a "heat dome" trapping warm air, and below-average rainfall. While the smoke has caused significant health warnings and property damage, it has also reignited diplomatic tensions. President Trump criticized Canada for "willful negligence" in forest management, while Canadian officials defended their efforts and noted that weather patterns affect both nations equally. Experts attribute the severity of this season to climate change, which has led to drier vegetation and more frequent heatwaves. The smoke is expected to continue moving south, impacting the eastern U.S. through the fall.
