"David Letterman has lined up his first television gig since retiring from 'Late Show' in May.

The comedian will appear as a correspondent in the second season of the climate change documentary series, 'Years of Living Dangerously,' which will premiere on National Geographic in October 2016, just ahead of the presidential election.

'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,' said Courteney Monroe, chief executive of National Geographic Channels, in a news release.  "
