Elizabeth Kolbert adds more perspective to the gap between policy and reality, with a look at the recent US-China emission agreement:
President Obama deserves a great deal of credit for the agreement, as does Secretary of State John Kerry, who conducted the behind-the-scenes negotiations. But, as many commentators have also noted, the deal doesn’t get the U.S. or China remotely near where they need to be if the world is to avoid disaster—which both countries, along with pretty much every other state in the world, have defined as warming of more than two degrees Celsius. Chris Hope, a policy researcher at Cambridge University, ran the terms of the agreement through what’s known as an “integrated assessment model.” He also included in his analysis a recent commitment by the European Union to cut its emissions by forty per cent before 2030. He found that even if all of the pledges made so far are fulfilled, there will be “less than a 1% chance of keeping the rise in global mean temperatures” below two degrees Celsius: “Most likely the rise will be about 3.8° C.”
On top of this rather nasty problem, there’s the issue of actually fulfilling the pledges. The Administration claims that reducing emissions by twenty-eight per cent over the next eleven years is “achievable under existing law.” This is a little like someone who’s trying to lose weight saying that his goal is “achievable” on a diet of doughnuts: it may be true in theory, but it’s extremely unlikely.
Well, Americans do love fad diets, though it is true that not many of them work, and some of them are dangerous. The real solution is to put a stiff tax on donuts, I mean carbon. The politics of doing that are of beyond comprehension at the moment. Still, understanding that pricing carbon is the single most important and indispensable policy step required to fight climate change would be a good first step.
