Letterman at the 2:40 mark: "The thing that I believe now is there's nothing that can be done about this--that's why they're not talking about it. I don't think there's a damn thing that can be done to recreate a climate in which glaciers will reproduce or come back...[John Holdren]...and his other buddies who work with Al Gore told me...if everybody started riding bicycles tomorrow, carbon [sic] emissions zero beginning tomorrow, this planet would continue to heat precipitously for 60 years...I think now, reasonably, it's all about adaptability".
