Canadian Wildfire Smoke Brings Severe Air Quality to Major US Cities
Canadian Wildfire Smoke Impacts US Air Quality
Smoke from approximately 120 active wildfires burning in Canada has drifted south across the border, bringing severely degraded air quality to major American cities. The affected metropolitan areas span from Chicago in the Midwest to Washington, DC on the East Coast.
The smoke has resulted in hazardous air quality conditions across multiple regions, with some areas experiencing pollution levels ranking among the worst on the planet. Residents in affected cities have been advised to limit outdoor activities and take precautions to protect respiratory health.
This event highlights the transboundary nature of wildfire impacts, with climate-related factors contributing to increasingly severe fire seasons in North America.
