In his recent posting “The collapse of Climate Policy and the Sustainability of Climate Science” (February 7, 2009), Roger A. Pielke, Jr. argues that the political consensus about climate policy is collapsing, because policy makers are realizing that it is unrealistic to expect that CO2 can be stabilized at 450 ppm. That such expectations are already in the realm of “fiction and fantasy” does not prevent some environmentalists from calling for even more impossible attainments, while confusing the relationship between science and policy-making.
Consider Bill McKibben’s essay in Mother Jones (November 10, 2008), “The Most Important Number on Earth.” McKibben, author of The End of Nature, maintains during the past year climate scientists have demonstrated that we are facing “the oh-my-lord crisis you drop everything else to deal with…” Claiming that we may have already reached the “tipping point” in global warming that may lead to “the collapse of human society as we have known it,” McKibben cites a recent paper by James Hansen et al. which calls for reducing CO2 from its current 385ppm to 350 ppm. For McKibben, this is the most important number on Earth. Above 350ppm, he warns us, “we can’t rule out a sea level rise of 20 feet this century.” (I would add that in the overheated climate change rhetoric, almost nothing can be “ruled out.”)
It goes without saying that for the vast majority of human beings, 350 is far from the most important number; indeed, for most people global warming is not regarded as a serious issue at all, in comparison with what’s facing them here and now. For a mother whose children are dying of malaria in central Africa, or for someone whose child is starving to death, 350 is not important.
McKibben comes up with the analogy of someone who, having been told by his physician that he has entered the cholesterol “danger zone,” knows that he must “clean the cheese out of the refrigerator and go cold turkey.” Presumably, the people he has in mind are those in advanced industrial societies–-and those aspiring to be in such societies–-who use vast amounts of fossil fuels. For McKibben, the energy equivalent to going cold-turkey would include: no more new more new coal plants, a cap on the amount of carbon the USA can produce, and an international agreement that requires China, India, and everyone else to do the same thing. Oh, and a rapid switch to $10 per gallon gasoline.
McKibben freely admits that achieving these extraordinary goals in a very compressed time frame “requires a new kind of politics. It requires forging a consensus that this toughest of all changes must happen. The consensus must be broad, it must come quickly, and it must encompass the whole earth–they don’t call it global warming for nothing.” (My emphasis.) The Internet, we are blithely told, will enable us to arrive at this global consensus. McKibben adds, however, that we have only until the 2009 Copenhagen Climate Meeting to forge a global treaty that will “get it right.” As he notes, “Once the ocean really starts to rise, dike building is pretty much the only project.” In short, we are doomed.
There are good reasons why policy makers have begun to regard with jaundiced eyes such absurd counsels of despair.
Now for the good part: McKibben tells us that the global political consensus necessary to institute his draconian policies will not be reached by political debate, give and take, and messy democratic compromises, but instead because this is “what the physics and chemistry of the situation dictate.” As Pielke would say, here is a prime example of: 1) a using the post-WWII linear model of science to justify and advocate policy decisions, and 2) attempting to turn Abortion Politics into Tornado Politics. Instead of engaging in value-laden discourse regarding the best course of action in challenging circumstances, we are supposed to let nature do the talking and instructing: “Permafrost, notoriously, refuses to bargain,” McKibben intones.
McKibben does not go so far as to describe the violence to which his technocratic regime would have to go in order to win “consensus” and to enforce on the entire human population the new rules of the game. Come to think of it, this new kind of politics doesn’t look so new after all.
