The George C. Marshall Institute has a long history of global warming denial, including publication of junk science reports funded by the American Petroleum Institute and authored by Sallie Baliunas, a scientist affiliated with several organizations receiving money from oil corporations.
The Marshall Institute also produced a "Cocktail Conversation Guide" with suggestions for denying the dangers of global warming in any social setting.
