Spring has been cool so far, but hot and sunny weather will come eventually, and with it smoggy air. What are the causes of smog (also known as ground-level ozone) and other kinds of air pollution in Kansas City? What policy changes do we need to make to reduce air pollution and clear the air, and what can individuals do right now? What impact could the Obama administration’s proposed new regulations to reduce sulfur content in gasoline have? Host John Kurmann will talk about all this with Amanda Graor of the Mid-America Regional Council’s Air Quality Program.
