I think this argument does not hold water. In short form, the reason is because this ignores the point that the reason the U.S., Europe and similar geographies have historically emitted carbon dioxide is that these societies invented the modern economy. Along with all that carbon dioxide the West put in the air, it also invented polio vaccine, the limited liability corporation, the high-efficiency power turbine and so on. While the West made a ton of money selling these things to what we now call developing countries, there were and are huge externalities because inevitably a lot of this knowledge leaks. The West invented the basic tools for increasing wealth that the successful parts of the developing world are now using to escape poverty, and incidentally emit more carbon dioxide. It is less than obvious why we would select only one of these items, and determine that we have a moral duty to make reparations for it, without considering that the net global effect of the overall system that created these emissions has been extremely positive. Ask yourself this question: Would you rather be born at the median income level in Bangladesh today, or at the median income level in Bangladesh in the alternative world where the entire Northern Hemisphere had never escaped life at the subsistence level.This strikes me as a strange reply. For one thing, the deal we're offering developing nations here doesn't seem to me to be all that great. We offer Bangladesh the polio vaccine and then make their country unlivable, and they're supposed to be grateful? Perhaps if we were prepared to welcome them en masse into our highly developed economy, but of course this is out of the question.
But the big error in thinking here is that it assumes that economic growth -- in the past and, crucially, in the future, cannot take place without this level of carbon emissions. You can have the polio vaccine and warming or neither, in other words, and those are your only choices. But of course, this is absurd. One might have said that we could have our modern economy and an ozone hole, or acid raid, but not both, but they'd have been completely wrong. Had the federal gas tax been indexed to inflation over the past two decades, it is quite likely that our national emissions would now be significantly lower with basically no observable decline in economic growth relative to today. And we probably would have continued to invent new medicines along the way.
Meanwhile, Will Wilkinson thinks he's stumbled onto a serious gotcha moment for "statist-liberals."
The idea is that coordinated international action toward carbon reduction is a global public good, and that the probability of effective coordination increases significantly if the U.S. acts unilaterally. HOW DOES THIS WORK? Standard statist-liberal reasoning about public goods is that they will not be provided unless there is a coercive mechanism in place (e.g., a state) to solve the assurance problem. But there is no state with global jurisdiction. So am I to understand that folks making the argument about the crucial role for Waxman-Markey in solving the international collective action problem don't really believe the standard story about the need for coercion in assuring compliance?This seems almost deliberately dense. In particular, it makes no distinction between the world of billions of daily, anonymous transactions and the world in which a handful of great powers attempt to hammer out a diplomatic agreement. Unsurprisingly, it's very difficult to get millions of urban denizens to voluntarily come together to build and fund a road network or transit system in the absence of a coercive mechanism. The benefits are too broadly shared, and the incentive to free ride too great. But the smaller the number of players, the more concentrated the benefits, and the easier it is to find a mutually beneficial agreement.
Now, it will be difficult to get every last microstate to sign on to a climate agreement, but it's obviously not necessary to get every last microstate to sign on to a climate agreement. The Vatican's impact on global emissions isn't worth discussing or pitching a fit over. In fact, there are fewer than ten relevant players, and only two really relevant players not already committed to reductions -- the US and China. Given that climate negotiations are part of a repeated game between the two great powers (that is, they're more or less constantly talking about one economic or political issue or another), it seems very likely indeed that an American pre-commitment to emission reductions would facilitate a similar Chinese commitment.
One doesn't really have to break one's brain to see how this might work. If America cuts emissions and China doesn't, a lot of warming still takes place. Once assured that it won't suffer an undue loss in competitive advantage, a country with large emissions that's interested in avoiding catastrophic warming (and this seems to describe China) will play ball.
Let me reiterate -- Waxman-Markey is a highly imperfect bill that will be totally inadequate in isolation and without further improvements. It would be better to pass a better bill. Here's the thing -- there is not a sufficient majority in Congress for a better bill. That seems clear. And at least part of the problem is that the GOP, which still has near-veto power over legislation, is largely home to individuals who think that warming isn't real, or isn't the result of human activity, or is most appropriately addressed by drilling for oil.
Will Wilkinson works for Cato, and Jim Manzi writes for National Review, two great outposts of climate change denialism and do-nothingism. It occurs to me that if more of their compatriots were willing to discuss the issue responsibly, then upwards of 90% of the GOP might not be committed to a policy based on utter stupidity, and a better bill might be feasible. Instead, they're busily arguing against Waxman-Markey. That's their right, but it certainly says quite a bit about their priorities.
