This Emmy Award-winning 9-part documentary series explores the global human impact of climate change, from the damage wrought by Superstorm Sandy to the upheaval caused by drought in the Middle East. Executive Produced by James Cameron and Arnold Schwarzenegger, the programs feature celebrity investigators alongside well-known journalists with a background in environmental reportage.

The celebrities include Harrison Ford, Matt Damon, Ian Somerhalder, Jessica Alba, Don Cheadle, America Ferrera, Michael C. Hall, Olivia Munn and Schwarzenegger. The journalists include Lesley Stahl, Thomas Friedman, Chris Hayes and Mark Bittman. The final episode includes Friedman's interview of President Barack Obama.
