Climate change is making it harder to meet clean air goals, says the 25th annual State of the Air report from the American Lung Association.
Wildfire smoke from Canada caused dangerously unhealthy air quality in New York City and across much of the U.S. in 2023. While air quality has improved greatly in the U.S. in recent decades, wildfire smoke and other climate-influenced problems are endangering that progress.Wildfire smoke from Canada caused dangerously unhealthy air quality in New York City and across much of the U.S. in 2023. While air quality has improved greatly in the U.S.
But in the West, 2023 had the most days ever recorded with dangerous or very dangerous air quality, measured by the Air Quality Index. And for the first time in the report's 25-year history, the 25 cities with the worst short-term particle pollution in the country were all in the Western U.S.The report highlights an increasingly clear challenge, says Susan Anenberg, an air quality expert at George Washington University and a consultant for the EPA.
Bakersfield, California, has stayed at the top of the report's list for the U.S. city with the worst short-term particle pollution in the country for five years. This time, it also got top billing for year-round particle pollution, too. The region is a major site of oil and gas production as well as agriculture, both of which produce significant local pollution.
Communities of color and low-income Americans have historically breathed in dirtier air than wealthier or whiter communities . The agency lowered the allowable pollution from 12 micrograms per meter cubed of air averaged over a year to 9—a major tightening, says Anenberg.
