From Sullivan:

It seems to me that the Bush administration has long held the sensible skeptical position (which does not preclude taking human impact on global warming seriously). The difference between them and Al Gore is that they don't take this as a certainty or buy the notion you have to throw the economy into reverse to prevent it.

So, it's ok to acknowledge that global warming exist and that it's very likely anthropogenic... as long as you don't (gasp) do anything about it.

Here's a fiddle, Andrew: Rome is calling, and it's piping hot.
