Wildfires Increase Smog Levels Across the U.S., Reversing Air Quality Gains
A recent study has revealed that smoke from wildfires is reversing years of progress in improving air quality across the United States. According to the National Interagency Fire Center, the average annual land burned by wildfires in the U.S. has increased by 9% compared to the period from 2003 to 2014. The situation has been exacerbated by severe wildfires in Canada, particularly in 2023, which saw record-breaking levels of land burned—double the previous record. Smoke from these fires caused significant particle pollution, leading to an estimated 82,100 global deaths, including 33,000 in the U.S. Scientists attribute much of this trend to climate change, which has intensified hot and dry conditions conducive to wildfires. However, other factors such as land management and meteorological variability also play a role.
