Well, you assume that those who would attempt to discredit the "consensus" are doing it only out of free market ideologies and not out of legitimate scientific dissent
Considering that the dissent is coming not from scientists, but from evidently biased businessman and politicians, I'd say my assumption is correct.
Incidentally, scientists who hold conservative political views are still firmly behind AGW. There's really no debate about it, as much as certain non-scientific types have tried to muddy the waters.
(Other similar cases where a political group may attach themselves to a view which goes against scientific consensus: consevatives are more likely to disbelieve evoltion, while liberals are more likely to believe vaccines cause autism. This isn't an isolated case.)
It's not just scientists, incidentally. I will turn around and point out the good of the free market here: there is a business for whom knowledge about this fact isn't just a matter of ideology, but essential to their business: insurance companies. Even if you can't trust scientists out of some paranoia about their politics (I don't think scientists tend to be a highly political group regardless, but you may disagree), you should be able to at least trust these guys.
This isn't to say that what we do about this fact can't be subject to politics, mind.
