GEORGE WILL, SYNDICATED COLUMNIST: No. And neither does science. But I'm one of those who are called deniers. And the implication is that I deny climate change. It's impossible to state with clearer precision the opposite of my view, which is that, of course the climate is changing. It's always changing. That's what gave us the medieval warm period. That's what gave us subsequent to that for centuries the brutal Ice Age. Of course it's changing. But when a politician on a subject implicating science, hard science, economic science, social science says the debate is over, you may be sure of two things. The debate is raging and he's losing it. So I think frankly as a policy question, Chris, Holman Jenkins, Kim's colleague at the "Wall Street Journal" put it perfectly, the only questions is, how much money are we going to spend? How much wealth are we going to forego creating in order to have zero or discernible effect on the environment?
