I've heard that the Newshour with Jim Lehrer (forever known to me as the McNeil/Lehrer Newshour) is likely(*) going to have a discussion tonight about climate change. This is probably motivated by the present heatwave. I've also heard that they're trying to get someone from the NAS Hockey Stick Panel to appear. I'll be tuning in.
[Addendum: They did not end up having any scientist on. Also, you can find a transcript and realaudio of the segment here.]
