The rule would require coal and natural gas plants to store 90 percent of their carbon dioxide emissions underground in about a decade.

Jonathan Raff, an IU professor who studies the chemistry of air pollution, said local weather conditions interact with wildfire smoke to worsen health outcomes for Hoosiers.

IDEM says we can reduce ozone by driving less, not refueling vehicles or using gasoline-powered lawn equipment until after 7 p.m., and setting thermostats to 75 degrees or higher.

With temperature forecasts in the 90s until Saturday, it’s likely poor air quality will continue for most of the week.

IDEM said hot weather and pollution from things like cars and factories create more ground-level ozone. That can make it more difficult to breathe and cause coughing.
