When an issue becomes a vital part of a political agenda, as is the case with climate, then the politically desired position becomes a goal rather than a consequence of scientific research.

...there is no substantive basis for predictions of sizeable global warming due to observed increases in minor greenhouse gases such as carbon dioxide, methane and chlorofluorocarbons.

In the long run, the replacement of the precise and disciplined language of science by the misleading language of litigation and advocacy may be one of the more important sources of damage to society incurred in the current debate over global warming.

I think it's [concern about global warming] mainly just like little kids locking themselves in dark closets to see how much they can scare each other and themselves.

The public discourse on global warming has little in common with the standards of scientific discourse. Rather, it is part of political discourse where comments are made to secure the political base and frighten the opposition rather than to illuminate issues. In political discourse, information is to be 'spun' to reinforce pre-existing beliefs, and to discourage opposition.

What historians will definitely wonder about in future centuries is how deeply flawed logic, obscured by shrewd and unrelenting propaganda, actually enabled a coalition of powerful special interests to convince nearly everyone in the world that CO2 from human industry was a dangerous, planet-destroying toxin. It will be remembered as the greatest mass delusion in the history of the world - that CO2, the life of plants, was considered for a time to be a deadly poison.

Climate science has been targeted by a major political movement, environmentalism, as the focus of their efforts, wherein the natural disasters of the earth system, have come to be identified with man's activities - engendering fear as well as an agenda for societal reform and control... This greatly facilitates any conscious effort to politicize science via influence in such bodies where a handful of individuals (often not even scientists) speak on behalf of organizations that include thousands of scientists, and even enforce specific scientific positions and agendas.
