re: New York' air quality plummets as Canada wildfires roar

We had this a few years ago in Chicago from wildfires in Canada. The smoke got really dense one day but cleared out a bit the next day and then fully moved out a few days later when the winds changed. For a time everything looked grey and orange and the smoke was miserable if you were outside.

It wasn't quite as bad as those pictures though. Looks horrible there in NYC.
