I shouldn't be surprised at SuperFreakonomics. Freakonomics reminded me somewhat of early John Stossel, while not the established wisdom they were glib "common sense" economic arguments. Like Stossel, later works veer more right and less factual. This latest seems to exhibit the bias toward particular approaches they decry in others. From The New Yorker review:
Given their emphasis on cold, hard numbers, it’s noteworthy that Levitt and Dubner ignore what are, by now, whole libraries’ worth of data on global warming. Indeed, just about everything they have to say on the topic is, factually speaking, wrong. Among the many matters they misrepresent are: the significance of carbon emissions as a climate-forcing agent, the mechanics of climate modelling, the temperature record of the past decade, and the climate history of the past several hundred thousand years.“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.”
Pierrehumbert carefully dissects one of the arguments that Levitt and Dubner seem to subscribe to—that solar cells, because they are dark, actually contribute to global warming—and shows it to be fallacious. “Really simple arithmetic, which you could not be bothered to do, would have been enough to tell you,” he writes, that this claim “is complete and utter nonsense.”
But what’s most troubling about “SuperFreakonomics” isn’t the authors’ many blunders; it’s the whole spirit of the enterprise. Though climate change is a grave problem, Levitt and Dubner treat it mainly as an opportunity to show how clever they are.
Leaving aside the question of whether geoengineering, as it is known in scientific circles, is even possible—have you ever tried sending an eighteen-mile-long hose into the stratosphere?—their analysis is terrifyingly cavalier. A world whose atmosphere is loaded with carbon dioxide, on the one hand, and sulfur dioxide, on the other, would be a fundamentally different place from the earth as we know it. Among the many likely consequences of shooting SO2 above the clouds would be new regional weather patterns (after major volcanic eruptions, Asia and Africa have a nasty tendency to experience drought), ozone depletion, and increased acid rain. Meanwhile, as long as the concentration of atmospheric CO2 continued to rise, more and more sulfur dioxide would have to be pumped into the air to counteract it. The amount of direct sunlight reaching the earth would fall, even as the oceans became increasingly acidic. There are eminent scientists—among them the Nobel Prize-winning chemist Paul Crutzen—who argue that geoengineering should be seriously studied, but only with the understanding that it represents a risky, last-ditch attempt to avert catastrophe.
“By far the preferred way” to confront climate change, Crutzen has written, “is to lower the emissions of greenhouse gases.”
Here is another notable review on two Vegetarian books.
