David Letterman will return to TV next year in a documentary series called "Years of Living Dangerously," which draws attention to the effects of climate change. The National Geographic series, which was renewed for a second season on Thursday, signed Letterman for his first television gig since he signed off as host of CBS' "Late Show," earlier this year.
Letterman will appear in one of the season's eight episodes, in which he will travel to India to explore how the country's government is trying to bring solar power to its entire population within the next decade, according to Variety.
"It's thrilling to have him do this - we're beyond excited," one of the show's producers Joel Bach said, according to The Hollywood Reporter. "The reason why Letterman's part of this is that we just noticed that he seemed to perk up when this issue came across his lap. We reached out to him to see if he'd want to be part of this, and he said, 'Absolutely.' He said [that climate change is] something he does think about a lot."
The show, which won Outstanding Documentary for Nonfiction Series at the 2014 Emmys, will also feature the likes of Ty Burrell, James Cameron, Don Cheadle, Arnold Schwarzenegger, Olivia Munn, Ian Somerhalder and Cecily Strong, according to The Huffington Post.
