CBC News: the fifth estate – The Denial Machine

The documentary shows how fossil fuel corporations have kept the global warming debate alive long after most scientists believed that global warming was real and had potentially catastrophic consequences. It shows that companies such as Exxon Mobil (exxposeexxon.org are working with top public relations firms and using many of the same tactics and personnel as those employed by Phillip Morris and RJ Reynolds to dispute the cigarette-cancer link in the 1990s. Exxon Mobil sought out those willing to question the science behind climate change, providing funding for some of them, their organizations and their studies.

The Denial Machine also explores how the arguments supported by oil companies were adopted by policy makers in both Canada and the U.S. and helped form government policy.
