Climate Change Back-and-Forth


I’m glad to see that Megan McArdle is confronting the reality that Waxman-Markey is very unlikely to work, either in the sense of providing benefits greater than costs, or in the sense of achieving anything like its stated goals, even without regard to cost.

I’m also glad to see that Ezra Klein is explicit about his acceptance that climate change is expected to have extremely limited effects on the United States for at least the next hundred years. I figure that ought to be pretty important when debating the proper policies for the government of the United States. On the other hand, we continue to disagree about the financial efficiency of the foreign aid program defined by transforming the energy sector of the American economy in order to very slightly ameliorate a predicted problem that might affect people who might live in low-lying equatorial regions of the world decades from now.
