Chris Hayes & David RobertsChris Hayes and David Roberts — together at last.Grist’s own David Roberts will play the role of talking head on MSNBC’s Up w/ Chris Hayes this Saturday morning. He’ll be joining Hayes and a few smart commentators to discuss climate change and other hot (ahem) topics in the news.

To catch it live, tune in 7:00-9:00 a.m. ET — or 4:00-6:00 a.m. PT. (Yes, that’s 4:00 in the morning.)

For you non-insomniacs out there, we’ll be posting the video after the show airs so you can enjoy David’s wit and wisdom at your leisure. As they say, stay tuned.
