Paul Krugman links to an excellent take-down by Elizabeth Kolbert of the notorious climate change chapter in Superfreakonomics.
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.
Kolbert’s closing words are, however, a little unfair.
To be skeptical of climate models and credulous about things like carbon-eating trees and cloudmaking machinery and hoses that shoot sulfur into the sky is to replace a faith in science with a belief in science fiction. This is the turn that “SuperFreakonomics” takes, even as its authors repeatedly extoll their hard-headedness. All of which goes to show that, while some forms of horseshit are no longer a problem, others will always be with us.
Not unfair to Levitt and Dubner, mind you, but to science fiction. After all, two science fiction authors, Frederik Pohl and Cyril Kornbluth, had their number down way back in 1953 with The Space Merchants (Pohl, amazingly, is still alive and active).
The Conservationists were fair game, those wild eyed zealots who pretended modern civilization was in some way “plundering” our planet. Preposterous stuff. Science is always a step ahead of the failure of natural resources. After all, when real meat got scarce, we had soyaburgers ready. When oil ran low, technology developed the pedicab.
