Freaked Out Over SuperFreakonomics
...Also smart are University of Chicago economist Steven Levitt and writer Stephen Dubner, whose delightful "SuperFreakonomics"—the sequel to their runaway 2005 bestseller "Freakonomics"—gives Myhrvold and Co. pride of place in their lengthy chapter on global warming. Not surprisingly, global warming fanatics are experiencing a Pinatubo-like eruption of their own.

Mr. Gore, for instance, tells Messrs. Levitt and Dubner that the stratospheric sulfur solution is "nuts." Former Clinton administration official Joe Romm, who edits the Climate Progress blog, accuses the authors of "[pushing] global cooling myths" and "sheer illogic." The Union of Concerned Scientists faults the book for its "faulty statistics." Never to be outdone, New York Times columnist Paul Krugman scores "SuperFreakonomics" for "grossly [misrepresenting] other peoples' research, in both climate science and economics."...

...But when it comes to the religion of global warming—the First Commandment of which is Thou Shalt Not Call It A Religion—Messrs. Levitt and Dubner are grievous sinners. They point out that belching, flatulent cows are adding more greenhouse gases to the atmosphere than all SUVs combined. They note that sea levels will probably not rise much more than 18 inches by 2100, "less than the twice-daily tidal variation in most coastal locations." They observe that "not only is carbon plainly not poisonous, but changes in carbon-dioxide levels don't necessarily mirror human activity." They quote Mr. Myhrvold as saying that Mr. Gore's doomsday scenarios "don't have any basis in physical reality in any reasonable time frame."

More subversively, they suggest that climatologists, like everyone else, respond to incentives in a way that shapes their conclusions. "The economic reality of research funding, rather than a disinterested and uncoordinated scientific consensus, leads the [climate] models to approximately match one another." In other words, the herd-of-independent-minds phenomenon happens to scientists too and isn't the sole province of painters, politicians and news anchors.

But perhaps their biggest sin, which is also the central point of the chapter, is pointing out that seemingly insurmountable problems often have cheap and simple solutions. Hence world hunger was largely conquered not by a massive effort at population control, but by the development of new and sturdier strains of wheat and rice. Hence infection and mortality rates in hospitals declined dramatically as doctors began to appreciate the need to wash their hands.

Hence, too, it may well be that global warming is best tackled with a variety of cheap fixes, if not by pumping SO2 into the stratosphere then perhaps by seeding more clouds over the ocean. Alternatively, as "SuperFreakonomics" suggests, we might be better off doing nothing until the state of technology can catch up to the scope of the problem.

All these suggestions are, of course, horrifying to global warmists, who'd much prefer to spend in excess of a trillion dollars annually for the sake of reconceiving civilization as we know it, including not just what we drive or eat but how many children we have. And little wonder: As Newsweek's Stefan Theil points out, "climate change is the greatest new public-spending project in decades." Who, being a professional climatologist or EPA regulator, wouldn't want a piece of that action?...
