I noticed this a couple of days ago when I drove over a bridge that usually gives me a great view of downtown:

You can thank Canadian wildfire smoke for haze/smoky sky across Philadelphia & most of Northeast. Smoke particles will mix down over next few days, so unhealthy breathing air for sensitive groups. At least we still get big break from heat/humidity. @NBCPhiladelphia @KYWNewsradio pic.twitter.com/m2Bm2Z0vy8

Why was the sun red in New York City and elsewhere on the East Coast today? Blazes burning in the Western U.S. and Canada sent smoke across the continent, contributing to a morning haze in the region. https://t.co/KFAcYUzCGG

Wildfires out west, mostly from Western Canada, have sent smoke all the way to the city. That smoke is creating the haze you're seeing this morning and giving the sun a red tint. 📸: Bronx - Soundview Neighborhood pic.twitter.com/Zx4AwZCOrY

See that haze on a clear day? That's smoke from Oregon in #RhodeIsland. pic.twitter.com/TALYaClLzK

Updated video: This is the NYC Wildfire Haze.

A skyline enshrouded - complete with a sickening acrid smell - from fires induced by our abuse of the planet. The AQI is 165. But the fires are 2500 miles away, in the Northwest.
