Wildfire season is starting. How Canadian leaders plan to respond - National

Canada’s wildfire season is getting started but it's not emerging as a hot topic in the federal election campaign so far. Here's what the parties have pledged.

Canadian Wildfire Smoke Cooled New York by 3 Degrees and Trapped Air Toxicants

Rutgers Health researchers from the Nanoscience and Advanced Materials Center (NAMC) at the Environmental Occupational Health Sciences Institute (EOHSI) found that wildfire particles created a microclimate effect that worsened pollution exposure.

When smoke from Canadian wildfires turned New York City skies apocalyptically orange in June 2023, it delivered catastrophic air quality and an unexpected side effect: cooling the New York City region by about 3 degrees Celsius.

Canadian wildfire smoke cooled New York by 3 degrees and trapped air toxicants

Like a smoky umbrella, wildfire smoke particles blocked incoming solar radiation, cooling the areas below. However, the cooling smoke layer also trapped harmful airborne contaminants.

The smoke from the massive Canadian forest fires stained the New York sky of a polluting orange in June 2023, which also cooled temperatures at about 3 degrees Celsius.

When the smoke of Canadian forest fires became the apocalyptically orange New York sky in June 2023, it offered catastrophic air quality and an unexpected side effect: cooling the New York area by about 3 degrees Celsius. This temperature drop, called "global gradient", which is the opposite of "heating [...]
