Ten years ago, Tracey Holloway, an atmospheric scientist at the University of Wisconsin–Madison, would have said that air pollution in the United States was a huge success story. “Our air had been getting cleaner and cleaner almost everywhere, for almost every pollutant,” she said. But in June 2023, as wildfire smoke from Canada spread, the air quality dropped to historically low levels in her home state of Wisconsin.
Just last month, the region’s air quality dipped once more to unhealthy levels. Again, wildfires were to blame.
While the US has made significant strides in curbing car and industrial pollution through setting emission limits on industrial facilities and automakers, the increasing frequency and intensity of fires are “erasing the gains that we have obtained through this pollutant control effort,” said Nga Lee “Sally” Ng, an aerosol researcher at Georgia Institute of Technology.

After thermal imaging appeared to show that xAI lied about suspected pollution at its Colossus supercomputer data center located near predominantly Black communities in Memphis, Tennessee, the NAACP has threatened a lawsuit accusing xAI of violating the Clean Air Act.
In a letter sent to xAI on Tuesday, lawyers from the Southern Environmental Law Center (SELC) notified xAI of the NAACP's intent to sue in 60 days if xAI refuses to meet to discuss the groups' concerns that xAI is not using the requisite best available pollution controls. To ensure there's time for what the NAACP considers urgently needed negotiations ahead of filing the lawsuit, lawyers asked xAI to come to the table within the next 20 days.
xAI did not respond to Ars' request to comment on the legal threat or accusations that it has become a major source of pollutants in Memphis.
