As ozone is most likely to soar to harmful levels in already polluted, heat island-shrouded urban environments, these findings do not bode well for America's major cities. Although the threat affects the country broadly, the scientists see certain regions that already struggle with foul air at risk of long stretches of unhealthy ozone. They say:

Unless emissions of specific pollutants that are associated with the formation of ozone are sharply cut, almost all of the continental United States will experience at least a few days with unhealthy air during the summers, the research shows. Heavily polluted locations in parts of the East, Midwest, and West Coast in which ozone already frequently exceeds recommended levels could face unhealthy air during most of the summer.

"It doesn’t matter where you are in the United States – climate change has the potential to make your air worse," said NCAR scientist Gabriele Pfister, the lead author of the new study. "A warming planet doesn't just mean rising temperatures, it also means risking more summertime pollution and the health impacts that come with it."
Those health impacts range from chest pain to congestion to coughing to shortness of breath. Ozone can worsen serious conditions like emphysema and bronchitis, and is especially harmful for children who have asthma. Breathing in ozone on a regular basis "may permanently scar lung tissue," says the EPA. The damage even stretches over to the world of trees, as certain species exposed to the stuff manifest stunted growth and messed-up leaves, like these guys:
