“The science is settled” is a slogan attributed by opponents of the Kyoto Protocol and global warming theory to supporters notably in the Clinton administration. There are no known examples of its use outside the skeptic press, though some of the statements that were made have similar implications. The slogan itself has therefore become a detail in the political debate [wp].
The use of this slogan by deniers is pretty much the very definition of a straw man argument: a misrepresentation of an opponent’s position in order to refute the misrepresentation, rather than the actual position. Despite the ubiquity of this statement in denialist discourse, one would be hard pressed to find a verifiable example of its use by proponents of the science of anthropogenic global warming.
But there does exist an example of its use by a ‘skeptic’. Here is S. Fred Singer, denier for hire, speaking at the 2008 International Conference on Climate Change in New York:
“For me, the science is settled. The cause is clearly, mostly natural. The human component, while it must be there, is negligible. We don’t see it.”
So who thinks – and has said – that “the science is settled”? S. Fred Singer, for one.
