Canada had its most destructive series of wildfires ever, and one expert says the country is currently on track this year to repeat that record-setting wildfire season in 2023.

More than 200 wildfires are raging across Canada, sending a thick blanket of choking smoke through the U.S. Midwest. Experts says climate change means U.S. residents better get used to it.

Many fires burning across Canada, forcing evacuations and threatening air quality in the United States, cannot simply be put out, authorities and experts say.

A Chicago Air Quality Alert has been extended through Friday as smoke from Canada wildfires has pushed the AQI into unhealthy levels across the region.

Canada’s wildfire season is off to an intense start. A NASA satellite has recorded thousands of hot spots across the country — four times the usual number for this time of year.

Smoke from wildfires raging in Canada has drifted into the United States, affecting air quality as far south as Florida.

Wildfire smoke was helping raise ozone to hazardous levels. No alerts have been issued, but the air quality may approach “code orange” levels again late Thursday afternoon in parts of the region, as it appears that the ozone factory will still be operating while the Canadian wildfire smoke persists in the skies over Philly.

Wildfires burning in Canada's oil-producing province of Alberta have reduced the country's daily crude production by about 7%. Here is a tally of affected oil production sites so far:

The rising impact of blazes in Canada and Siberia’s boreal regions over the next 35 years will slow warming by 12 per cent globally and 38 per cent in the Arctic, according to recent climate modelling research at the University of Washington (UW).
