Denver was under pollution alert Monday after suffering the worst air quality among the world’s major cities over the weekend -- and another round of smoke is in the forecast for Tuesday.
The Colorado capital was ranked No. 1 on the IQAir pollution index Saturday afternoon and slipped to No. 2 on Sunday as smoke from California wildfires blanketed the city at the base of the Rocky Mountains.
