What's the paradox for someone who believes the anthropogenic contribution to global warming is too negligible to warrant action?

As I first pointed out, there's no paradox if one examines the metaphysical and epistemological issues carefully. An individual engaging in sloppy (i.e. typical) epistemology may fall into a paradox (i.e. engage in hypocrisy) if he's not careful, but that doesn't mean a paradox is intrinsic to the issue. It's intrinsic to poor critical reasoning skills.
