Good grief
When science tells us that public policy should change, that is politics...good politics. Your idea that politics happens independent of the real world is absolutely ridiculous. If politicians fail to factor science into public policy we all lose. They need to be held to account for those failures.
Keep in mind I didn't say "it is all Bush’s fault." I said its high time he do something about public policy so that it follows from the best advice the best available science has to tell us. Its time to get serious about green house gasses. Its time Mr. Bush get serious about them.
