Read the credits for the new Showtime series "The Years of Living Dangerously," and you'd be forgiven for thinking it's an edge-of-your-seat Blockbuster of epic proportions.
Produced by James Cameron and Arnold Schwarzenegger, the show features stars from Matt Damon and Don Cheadle, to Jessica Alba and even Indiana Jones himself, Harrison Ford. But despite the list of exotic shooting locales, this is not some fictional swashbuckler.
It's a documentary series about global climate change and how it's affecting real people. We're joined by Heidi Cullen, chief science advisor for the series.
