Last week environmental activist Bill McKibben appeared on the Late Show with David Letterman to discuss everything from the science of climate change and the obstructive power of the oil, coal, and gas lobbies, to China's rapid economic expansion and our political logjams in the United States, to the genesis of 350.org and the upcoming 10/10/10 Global Work Party.
After the clip cuts out, there are another 30 seconds or so of dialogue, continued below.
Letterman: "But is what you're talking about adaptability really rather than correcting any of this?
McKibben: "You can adapt, maybe, to one or two degrees. You can't adapt to four or five degrees, so we've got to do both."
Letterman: "Special hats. Have you thought about special hats?"
McKibben: "There you go. Those'll help."
Letterman: "That's where my money is, ladies and gentlemen, special hats. Well Bill, thank you for just scaring the crap out of me."
