In the cities of Kelowna and Kamloops, the air quality index (AQI) was above 350, a "hazardous" level, real-time air quality information platform IQAir showed. Wildfire smoke is a seasonal occurrence for much of heavily-forested British Columbia, but the number of wildfires and amount of land burned is trending higher as a result of climate change, increasing concerns about the impact on human health. "This type of extreme smoke event covering all of our province does not happen every year," said Jalena Bennett, smoke information specialist with BlueSky Canada, adding 2018 was the last time wildfire smoke was so widespread.
