WASHINGTON, Sept. 17 (UPI) -- David Letterman, Olivia Munn, Jack Black, Ty Burrell and James Cameron are to appear on Season 2 of the climate change-themed, docu-series Years of Living Dangerously.

Also tapped as correspondents for the program will be Thomas Friedman, Joshua Jackson, Aasif Mandvi, Arnold Schwarzenegger, Ian Somerhalder and Cecily Strong. The celebrities will all give first-person accounts from various locations where the effects of climate change are most prevalent.

National Geographic Channel and The Years Project announced the show's casting Thursday.

The new season of the critically acclaimed series will air exclusively on NGC in 2016 in 171 countries and 45 languages.

"Years of Living Dangerously is bold, audacious and has a proven track record. By combining the access and reputation of National Geographic with Hollywood's brightest minds and journalism's heaviest hitters, we plan to create even greater impact with the new season and awaken all of us to the reality of our global situation," Courteney Monroe, chief executive officer of National Geographic Channels, said in a statement. "National Geographic has an unrivaled 127-year history of inspiring people to care about the planet, and this series will carry on that legacy and be supported by the incredible global reach of the National Geographic brand that is unmatched in television today."

"With the unparalleled global reach and inside access of National Geographic, we are going to raise the bar even higher this season and shed light on the catastrophic changes taking place on our planet through the lenses and investigative reporting of top Hollywood influencers," added Joel Bach from The Years Project. "We're also going to focus much more this season on solutions that individuals, communities, companies and even governments can use to address worldwide climate change."

"Communicating more effectively about the need to create a clean-energy future is my mission and I am honored to be given the opportunity once again to be a part of this very evocative series," stated returning contributor and executive producer Schwarzenegger. "It is absolutely unacceptable that 7 million people die every year from pollution. The time for action is now. This season, I hope to make an even more powerful statement that will inspire people to lead and demand change to make our world a better place for future generations."
