I think most climate change/global warming deniers are motivated by politics. On the denier side, it's pure political calculus, on the consensus side, it's scientific consensus + some political calculus.

This is not to say that some or many or even most on the denier side have any economic stake in the debate, in fact often they would be better off financially siding with the scientific consensus. Somebody's got to do the physical job of building environmentally efficient infrastructure, mostly the denier movement benefits the current batch of capitalist rulers.

But as long as a certain minimal standard of living is available to the masses quite a bit of our political leanings are determined by pure pride in whatever party they have selected and abstract ideological concerns, rather than personal interest.
