Princeton physics professor William Happer says the notion that carbon dioxide is some sort of pollutant that’s causing harm in the world is based on a myth. It’s that myth that serves as the basis for much of the alarmist argument surrounding global warming.

Happer rebutted the myth during a presentation to the John Locke Foundation’s Shaftesbury Society. (Download a PDF of his presentation slides here.)  In the video clip below, Happer summarizes his key arguments and discusses reaction to the truth about carbon dioxide and the changing climate.
