The Global Climate Coalition, a group of representatives of the oil, auto and coal industries, spent years telling the public that the link between human activity and climate change was too uncertain to justify U.S. participation in the Kyoto Protocol, a 1997 treaty aimed at curbing greenhouse gas emissions. They have been accused of doctoring information prepared by their scientific experts before releasing it to the public.

Al Gore former US VP accused the coalition of committing fraud  and telling lies to people who trusted them, in order for the industry to make money.  This he highlighted before the House Energy and Commerce Committee where he equated the cause of global warming legislation with the civil right legislation of the 1960s and the Marshall Plan of the 1940s.

John Kerry pointed out on the need to be wary of some of the industry studies and analyses that will come out in the months as Congress debates whether to impose a mandatory limit on greenhouse gas emissions.
