A column by Robert Samuelson in the Washington Post has conservatives all a-twitter -- appropriate, I guess, since it gathers all the state-of-the-art conservative talking points on global warming in one place.
Browse around at reactions and the impression you will get above all is that conservatives just don't take the subject very seriously. They're looking for some clever arguments so they can move onto other stuff that gets their viscera churning (terrorism, evil liberals, etc.). This headline is typical: "WaPo: Global Warming a Bunch of Bull."
Of course, that's not what the column says at all. What the column says is that we can't really do anything about global warming, and any politician who says otherwise is a hypocrite. It advocates despair and surrender.
There are two primary points in the column, and one conclusion that follows from the two points. Let's take them in order.
