Charles Krauthammer and Global Warming

This paragraph from his recent article fairly sums up my view on global warming.

I'm not a global warming believer. I'm not a global warming denier. I'm a global warming agnostic who believes instinctively that it can't be very good to pump lots of CO2 into the atmosphere, but is equally convinced that those who presume
to know exactly where that leads are talking through their hats.

"Hats" isn't exactly the word I would use, but then I suppose that depends on where a person's head is located.
