Story Spark: Wildfire Smoke

The document outlines the health risks of wildfire smoke, specifically PM2.5 particulates, and provides guidance for reporters on highlighting vulnerable populations and using tools like the Air Quality Index (AQI). It notes that wildfire smoke can be up to 10 times more harmful in the short term than industrial pollutants and cites a study estimating 70,000 annual deaths in the US by 2050.

• Wildfire smoke is significantly more hazardous than pollutants from cars and factories, with short-term harm potentially being up to 10 times greater. It contains fine particulates known as PM2.5 that penetrate deep into the lungs and can cause heart attacks, strokes, asthma attacks, and pre-term deliveries.
• Climate warming is expected to increase the frequency of smoke events, with one study projecting that wildfire smoke will cause 70,000 deaths per year in the United States by 2050.
• Certain populations face disproportionate risks from wildfire smoke, including children, the unhoused, people with cardiovascular or respiratory diseases, and Indigenous communities. In Canada, Indigenous and First Nations people represented 42% of all forest-fire-related evacuations between 1980 and 2021, despite being only 5% of the population.
• Exposure to wildfire smoke has immediate and severe health consequences; for example, smoke covering the northeastern US and Great Lakes between July 15 and 23 is linked to approximately 4,000 premature deaths.
• Research from Berkeley Earth indicates a direct correlation between smoke exposure and cigarette smoking, where 24 hours of exposure to 22 micrograms of wildfire smoke per cubic meter of air is equivalent to smoking one cigarette per day.
