What He Said: David Letterman on Global Warming

"I'm a little disturbed about something and I think it's the heat. In fact, I know it's the heat. You know when you hear the phrase 'global warming' -- I wonder if that's happening now. You know, cause it's just hotter than it oughta be. Or is it fine? Are we confortable with 110 degrees? Is that all right?" -- David Letterman (via Treehugger)
