Researchers are warning that the thick clouds of smoke from wildfires in eastern Canada, which blanketed the U.S. East Coast in a dangerous orange haze, are a sign of the times. The current fires were sparked by lightning in the Canadian province of Quebec; like much of Canada, parts of Quebec were abnormally dry this spring.
Their smoky haze has dominated headlines, prompting warnings of dangerous air pollution levels. People were urged to stay indoors as much as possible, or wear masks, to avoid inhaling the fine particulate matter. The smoke, a toxic brew of irritant gases and tiny particles, can cause asthma, respiratory and cardiovascular problems, and can exacerbate existing conditions such as diabetes and chronic lung conditions (SN: 6/17/22; SN: 9/18/20).
Wildfire-driven air pollution is all too familiar to residents of the Pacific Northwest and the U.S. West, where most of the continent’s large wildfires occur, but it’s less common in the eastern part of North America. So June’s headline-grabbing haze might be a wake-up call to East Coast policy makers about the hazards of climate change, some researchers hope.
