Major cities including New York, Philadelphia and Washington woke up to unhealthy levels of air pollution on Thursday, a day after the air quality in New York reached historically bad levels, climbing into the most severe tier of the Environmental Protection Agency’s six-tier index. Gov. Kathy Hochul of New York called the worsening air quality “an emergency crisis.” Although conditions in the Northeast on Thursday were expected to be better than the day before, the noxious air was spreading across a growing part of the country, with air quality alerts extending west to Indiana and as far south as the Carolinas.
