Do you feel that pointing at China is productive, KS? With their economic and infrastructure growth and modernization, they'll be a poster boy for CO2 generation for years to come. I don't see how an "I'll take action, but not until you take action" posture is an effective strategy. If the US could boost our economy at the cost of some additional CO2 emission I am sure that we would allow that to happen.

Power generation is just one sector that contributes CO2, but China is taking steps to reduce CO2 emissions even if air pollution may be the primary driver. Recent news has China cutting back on coal plant construction:

Nuclear power plant construction provides an even greater contrast between China and the US.

I don't see any productive thoughts coming from the current administration, not given the number of AGW deniers (call them skeptics if you want, but that's a pass) in key roles.
