I’ve let my Monthly subscription lapse (will resubscribe as soon as I get a moment), so I can’t read the latest piece by Robert Manne, only the summary by John van Tiggelen, but the basic argument is simple, and widely shared. Climate change policy in the US has gone nowhere thanks to the intransigent opposition of the Republicans. I have a couple of comments
First, the policy situation isn’t nearly as bad as might be supposed, given the failure of the Waxman-Markey cap-and-trade bill, and the absence of any real push from the Administration. The fact is, that, in the current US situation, achieving coherent outcomes from legislation is just about impossible. Increasingly, the Obama Administration relies on executive and regulatory actions. In the case of climate change, the important ones are fuel economy standards for cars (CAFE), and EPA regulation of CO2 emissions and other pollution from power stations. Obama has pushed through rules requiring a near doubling of fuel efficiency by 2025. The EPA regulations effectively make new coal-fired power stations uneconomic and require the shutdown of many old stations previously exempted from the Clean Air Act. Reliance on executive action has all sorts of problems, and regulation is an inefficient way of reducing emissions. Still, if Obama is re-elected, the US can expect to see continued reductions in emissions over the rest of the decade. It’s important to observe that, even with the current limited policies, US emissions have already peaked and begun to decline. If Obama wins, the EPA and CAFE regulations will be locked in, and there’s the potential to go further, particularly in the context of an agreement with China.
Second, while its unfortunate that climate change has been entangled in the general craziness of the modern Republican party, this process hasn’t been costless for the Repubs. Given the state of the economy, they ought to be looking forward to a whitewash in November. Instead, Romney is expected to lose, and any Repub Congressional majority will be narrow and fragile. That’s not specifically because of climate change, but a result of the entire political approach taken by the Repubs for the last 20 years, of which delusional claims about climate science are just one example. Whereas until the 1990s, there was a steady drift of disillusioned leftists/liberals (both intellectuals and ordinary voters) to the right, the process is now going in reverse.
