Why Levitt and Dubner like geo-engineering and why they are wrong

Many commentators have already pointed out dozens of misquotes, misrepresentations and mistakes in the ‘Global Cooling’ chapter of the new book SuperFreakonomics by Ste[ph|v]ens Levitt and Dubner (see Joe Romm (parts I, II, III, IV, Stoat, Deltoid, UCS and Paul Krugman for details. Michael Tobis has a good piece on the difference between adaptation and geo-engineering). Unfortunately, Amazon has now turned off the ‘search inside’ function for this book, but you can read the relevant chapter for yourself here (via Brad DeLong). However, instead of simply listing errors already found by others, I’ll focus on why this chapter was possibly written in the first place. (For some background on geo-engineering, read our previous pieces: Climate Change methadone? and Geo-engineering in vogue, Also the Atlantic Monthly “Re-Engineering the Earth” article had a lot of quotes from our own Raypierre).

Paul Krugman probably has the main issue right:

…it looks like is that Levitt and Dubner have fallen into the trap of counterintuitiveness. For a long time, there’s been an accepted way for commentators on politics and to some extent economics to distinguish themselves: by shocking the bourgeoisie, in ways that of course aren’t really dangerous.


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.

Levitt was on NPR at the weekend discussing this chapter (though not defending himself against any of the criticisms leveled above). He made the following two points which I think go to the heart of his thinking on this issue: “Why would anyone be against a cheap fix?” and “No problem has ever been solved by changing human behaviour” (possibly not exact quotes, but close enough). He also alluded to the switch over from horse-driven transport to internal combustion engines a hundred years ago as an example of a ‘cheap technological fix’ to the horse manure problem. I deal with each of these points in turn.

Is geo-engineering cheap?
