Interview with James Hoggan, the author of Climate Cover - Up: The Crusade to Deny Global Warming, an expose of how the false debate on climate change was manufactured by oil and gas companies and their PR firms. Hoggan, who works in the public relations industry himself, holds this manufactured debate up as bad PR practices by traditional energy companies trying to convince the public of untruths about their environmental impacts, rather than doing the right thing and greening their operations. In this Green Interview, Hogan discusses the climate change deniers, the use industry-sponsored propaganda and how ethical business should be conducted.
