(What's So Funny 'Bout) Peace, Love and Global Warming?

As you walk through this wicked world searching for light in the darkness of insanity, do you ever ask yourself, 'Is all hope lost?' If so, then man oh man, are you ever in need a good laugh.

You're in luck: This Sunday, on TBS, a slew of comedians including such yukmeisters as Jack Black, Steve Martin, and Bill Maher will mine the rich comic vein that is global warming. The 2-hour show, called Earth to America!, airs at 8/7 Central.

In preparation for the event (airing live from Caesars Palace in Las Vegas -- pretty much the poster child for unsustainable America, wouldn't you say?), Grist chats with Larry David of Seinfeld/Curb Your Enthusiasm fame. In what sounds rather like a sitcom plot, it seems Larry's been dragged into the eco-trenches by his firebrand wife, Laurie David. For an MTV campaign called Curb Global Warming, Laurie gives away Larry's Prius. Hilarity ensues.
