Smoke from an unusually high number of more than 400 wildfires in Canada is drifting across the U.S. border, turning skies hazy over the Midwest and Eastern states and forcing Americans to take precautions against breathing in harmful pollutants.
Air quality has declined in states from Minnesota to the Carolinas. Public schools in New York City and Washington, D.C., have canceled outdoor activities.
New York and Detroit ranked among cities with the worst air quality in the world as of Wednesday morning, according to IQAir, a Swiss air-monitoring source. New Yorkers were urged to wear pandemic-era masks to protect against the smoke.
