The Heartland Institute's new poster campaign. I'm sort of still wondering if it's going to turn out to be a joke, but... from their press release (via Leo Hickman):

The people who still believe in man-made global warming are mostly on the radical fringe of society. This is why the most prominent advocates of global warming aren’t scientists. They are murderers, tyrants, and madmen.

I think Heartland just became the new Monckton: if they didn't exist, we'd need to invent them.
