Los Angeles, Sep 18 (IANS): Veteran comedian David Letterman will reportedly visit India in 2016 to examine how the country is trying to bring solar power to its entire population within the next decade.

Letterman will join Arnold Schwarzenegger, Jack Black, Ty Burrell, James Cameron, Thomas Friedman among others in the second season of National Geographic's Emmy Award-winning documentary series "Years of Living Dangerously", which explores the issue of climate change, reports variety.com.

The project is the first Letterman has announced since leaving "The Late Show" on CBS last May.

A spokesman for Letterman said the comedian declined to comment.

Letterman’s new endeavour may have some serious intent behind it. David Gelber and Joel Bach, the series' producers, said they thought they noticed Letterman become more animated on "The Late Show" when discussion of climate change came to the fore, and decided to reach out to him.

"You could just tell. Whenever they would have a climate discussion, he would really kind of perk up," noted Bach in an interview.

"And it turns out he does, he cares about it a lot. He's definitely invested in this issue," he added.

Letterman, the producers said, has never visited the country.
