Professor Raymond T. Pierrehumbert, Louis Block Professor 
in the Geophysical Sciences at the University of Chicago Geosciences, has published An Open Letter to Steven Levitt, the nation’s Super Freakiest Economist. To put it simply, Pierrehumbert owns Levitt.
By now there have been many detailed dissections of everything that is wrong with the treatment of climate in Superfreakonomics , but what has been lost amidst all that extensive discussion is how really simple it would have been to get this stuff right. The problem wasn’t necessarily that you talked to the wrong experts or talked to too few of them. The problem was that you failed to do the most elementary thinking needed to see if what they were saying (or what you thought they were saying) in fact made any sense. If you were stupid, it wouldn’t be so bad to have messed up such elementary reasoning, but I don’t by any means think you are stupid. That makes the failure to do the thinking all the more disappointing.
Pierrehumbert then takes one specific point from the chapter to highlight this “failure to do the thinking”. Pierrehumbert’s examination of the issue of whether solar cells’ low albedo (high absorption of solar energy & thus heat) makes it senseless to pursue solar power provides a tour de force examination of the basics of research (using the web) and how Levitt seems to have totally flubbed.
The point here is that really simple arithmetic, which you could not be bothered to do, would have been enough to tell you that the claim that the blackness of solar cells makes solar energy pointless is complete and utter nonsense. I don’t think you would have accepted such laziness and sloppiness in a term paper from one of your students, so why do you accept it from yourself? What does the failure to do such basic thinking with numbers say about the extent to which anything you write can be trusted? How do you think it reflects on the profession of economics when a member of that profession – somebody who that profession seems to esteem highly – publicly and noisily shows that he cannot be bothered to do simple arithmetic and elementary background reading. Not even for a subject of such paramount importance as global warming.
Rather than seeking to summarize or crib his work, let me simply emphasize that Pierrehumbert’s discussion is highly recommended reading — for the substance and style.
