Wildfires spark a new peak in pollution

New study warns of emerging problem

A study by the National Center for Atmospheric Research (NCAR) published this week examined 16 years of data and found that wildfire emissions have increased so substantially that they’re changing the annual pattern of air quality across North America. Scientists found a new peak of air pollution in August, which didn’t use to exist. The summer months have historically been a time when carbon monoxide levels have remained low. The research team tracked wildfire emissions from 2002 to 2018 alongside computer modeling to analyze the potential impacts of the smoke, focusing on three regions: the Pacific Northwest, the central U.S., and the Northeast. They found that the trend became more pronounced from 2012 to 2018 when the Pacific Northwest fire season became more active, drawing a direct coalition between the smoke’s impact and the higher levels of harmful emissions. The findings were particularly striking since carbon monoxide levels have otherwise been decreasing -- globally and across North America -- due to improvements in pollution-control technologies.

This new data add to an already alarming trend. In 2016, researchers at Climate Central noted that the annual average wildfire season in the western U.S. was 105 days longer than it was in the 1970s, burned six times as many acres, and had three times as many large fires (burning over 1,000 acres). According to AccuWeather Meteorologist Brandon Buckingham, this year’s wildfire season is expected to be another active one, with the number of fires and acreage burned already running well above the 10-year average to date. AccuWeather’s forecasters expect an above-normal wildfire season in 2022, with early predictions of 67,000-70,000 fires.
