I never said rich nations shouldn't cut their emissions. If I were king, I'd enact a heavy carbon tax, and I'd tell every country I traded with that they could either do the same, or face tariffs and sanctions weighted by emissions that would have basically the same effect on their economy. I'd also insist that the institute the same tariffs and sanctions on economies they trade with.

All of a sudden, you'd have the world's short term self interest aligned with solving the long term problem.
