And while the noxious smoke was finally easing over the northeast on Friday, the fires still posed a major threat.
More than 420 fires are raging across Canada from British Columbia in the west to Nova Scotia in the east. At least half of these fires are burning out of control, and tens of thousands of people have been evacuated from their homes.
While air quality improved in large cities like New York, Washington DC and Philadelphia on Friday, pollution increased across central and southern states including the cities of Chicago, Cincinnati, Pittsburgh and Cleveland.
Global temperature rise, caused by emissions from burning fossil fuels, is leading to more large, erratic wildfires around the world. And it’s a vicious circle: the emissions pumped into the atmosphere by fires add to global heating, further drying out the land and vegetation, making it more susceptible to catching fire.

Canada’s wildfire season starts early with a ferocious wave of blazes
Canada’s wildfire season started early this year and accelerated very quickly, exhausting firefighting resources across the country, Canadian Interagency Forest Fire Centre spokesperson Jennifer Kamau said.
Smoke from the blazes in various parts of the country has been lapping into the U.S. since last month but intensified with a recent spate of fires in Quebec, where more than 100 fires were burning and considered out of control Tuesday.
The largest town in Northern Quebec — Chibougamau, population about about 7,500 — was evacuated Tuesday, after another Quebec community was left to burn Monday, drawing the ire of local residents.
Quebec Premier François Legault said Monday that authorities had no choice because the fire around the hamlet of Clova was too intense to send in water bombers. That remained true Tuesday, he said, but he noted that no homes had burned.
Kamau said more than 950 firefighters and other personnel have already arrived from the U.S., Australia, New Zealand and South Africa, and crews from Costa Rica will be arriving soon.
Across the border, the effects of the blazes blotted out skylines and irritated throats.
“It’s sunny, but there’s no sun,” Michele Kluk said as she emerged from a Target store in Mechanicsburg, Pennsylvania, with “a bunch” of allergy medication in response to the air quality.
