The Denial Machine

In the past few years, a hurricane has engulfed the debate about global warming. This scientific issue has become a rhetorical firestorm with science pitted against spin and inflammatory words on both sides.

The Denial Machine investigates the roots of the campaign to negate the science and the threat of global warming.
