Fresh from the clogged tubes of teh intarwubs…
"If the discussion around AGW (or evolution, or vaccinations) was solely scientific — with the use of relatively objective evidence, open analysis, and a willingness to learn from mistakes — the disbelievers would quickly lose all standing. The scientific evidence for AGW is simply so overwhelming that the only way to perpetuate a "debate" is by playing the belief card. As long as AGW deniers and "skeptics" can keep the framing religious, they can maintain their perceived legitimacy.
As far as I know, Steven Levitt does not adopt an explicitly religious view of the issues discussed in his book, and might even take offense at being lumped in with anti-vaxxers and creationists. But he's the one who has decided to frame his arguments in the language of faith and belief. The lesson is here is simple: pay attention to language. The messages and meanings underlying the terms chosen by interest groups can say more about them than they might intend." Cascio nails that shit to the wall.
