Is Tony Snow an Idiot or a Liar?

It's a serious question:

Tony Snow: "there is a carbon cap system in place in Europe; we are doing a better job of reducing emissions here."

First of all, neither the U.S. nor Europe are reducing their carbon emissions. In fact, none of the countries which signed the Kyoto Treaty have done so. But Europe is trying to reduce the rate of growth of emissions, with some (very modest) success, while the U.S. is literally doing nothing at all.

Think what you will about the science of climate change and the politics which surrounds it, but this statement by Snow is patently false, and he has to know it. He should not be speaking for the leader of the government of the United States.
