Cutting carbon dioxide emissions from power plants would also reduce other types of air pollution, both here in Missouri and nationally.

That's according to a recent analysis by researchers at Harvard and Syracuse Universities.

Along with carbon dioxide, coal-fired power plants emit other pollutants, like sulfur dioxide and nitrogen oxides. Those in turn can contribute to forming particle pollution, ozone, and smog.

has high levels of ozone pollution, the main ingredient in smog.

The annual State of the Air report ranked St. Louis 13th out of 217 metro areas in the country for ozone pollution. That’s worse than St. Louis performed in last year’s report, although the trend over recent decades has been gradual improvement.

It’s a stretch to think about summer now. 

But close your eyes and imagine.

The sun is shining; bees are buzzing; your arms move through warm air; you even have to mop a thin veil of perspiration from your brow. And on the news in the morning, Geri Mitchell intones the familiar admonition: “It’s a red air quality day. Sensitive groups should avoid exercising outdoors.”

A new report released today by the Natural Resources Defense Council warns that smoke from wildfires poses health risks to people living far from the actual blaze.

The study used data from 2011, an especially bad year for wildfires in the US, to rank states with the greatest number of residents affected by wildfire smoke for longer than a week.

Illinois and Missouri were ranked second and fourth respectively, despite having no wildfires of their own.

If you happen to be near the Saint Louis Science Center planetarium at around 2 o’clock in the afternoon, look up. You might see a weather balloon.

Students at Saint Louis University are launching them as part of a study sponsored by the U.S. space agency NASA.

The mission aims to improve our understanding of air pollution and global climate.
