First, there was the book Superfreakonomics by Levitt and Dubner that offered in part what looked like some interesting ideas about reducing global warming. The Wall Street Journal then wrote this piece in support, which concluded that
Part of the genius of Marxism, and a reason for its enduring appeal, is that it fed man’s neurotic fear of social catastrophe while providing an avenue for moral transcendence. It’s just the same with global warming, which is what makes the clear-eyed analysis in “SuperFreakonomics” so timely and important.
Columnist Paul Krugman raises a good point about the book in his short review, that a Clever snark like this can get you a long way in career terms — but the trick is knowing when to stop. It’s one thing to do this on relatively inconsequential media or cultural issues. But if you’re going to get into issues that are both important and the subject of serious study, like the fate of the planet, you’d better be very careful not to stray over the line between being counter-intuitive and being just plain, unforgivably wrong.
So who is right, or more importantly, unforgivably wrong?
To help you sort out the information, Real Climate offers what seems to me to be a thorough review here, ending with:
To conclude, the reasons why Levitt and Dubner like geo-engineering so much are based on a misreading of the science, a misrepresentation of proposed solutions, and truly bizarre interpretations of how environmental problems have been dealt with in the past. These are, in the end, much worse errors than their careless misquotes and over-eagerness to shock highlighted by the other critiques. Geo-engineering is neither cheap, nor a fix, and the reasons why it is very likely to be a bad idea are ethical and legal, much more than its still-uncertain scientific merits.
