From Bret Stephens at The Wall Street Journal:
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?
Part of the genius of Marxism, and a reason for its enduring appeal, is that it fed man’s neurotic fear of social catastrophe while providing an avenue for moral transcendence. It’s just the same with global warming, which is what makes the clear-eyed analysis in “SuperFreakonomics” so timely and important. (Now my sincere apologies to the authors for an endorsement that will surely give their critics another cartridge of ammunition.)
