"The recent devastation on the East Coast is a tragic reminder of the direct link between our daily lives and climate change," Showtime Networks' president of entertainment David Nevins said. "This series presents a unique opportunity to combine the large-scale filmmaking styles of James Cameron, Jerry Weintraub and Arnold Schwarzenegger — arguably some of Hollywood's biggest movie makers — with the hard-hitting, intimate journalism of '60 Minutes' veterans Joel Bach and David Gelber.  I believe this combination will make for a thought-provoking television event."

“We’ll make it exciting,” added Cameron. “We’ll make it investigative. We’ll bring people the truth. And people are always hungry for the truth.”

In addition to the narrators, "Years of Living Dangerously" will use reporting from the field, with New York Times journalists Thomas Friedman and Nicholas Kristof, columnist Mark Bittman and MSNBC host Chris Hayes.

"Years of Living Dangerously" will air over six to eight one-hour episodes, Showtime said.
