This post covers who should watch the (deeper than usual) video "Climate Change: What We Know and How We Know It" by (Republican) geochemist Barry Bickmore, and what the talk addresses.
Climate videos aimed at the general public tend not to be satisfying to people who want to understand how the physics applies; but for these physics seekers, this video might fit the bill. Starting with some discussion of a "radiant energy bathtub" metaphor, Bickmore spends the first half hour going over climate physics, then goes on to cover estimating "the holy grail", climate sensitivity, & addressing possible natural & human causes of climate change.
Though informal, it is a lecture & not entertainment; but he covers a lot of ground in an hour & a half, and for those who want physics in their big picture, this video's likely to be ideal.
(In a comment there, I've noted which topic gets covered when, so if you just want to hear about, say, climate sensitivity, you can just navigate to that particular segment.)
If you like this one and want more, Richard Alley's 2009 AGU lecture "The Biggest Control Knob: Carbon Dioxide in Earth’s Climate History" is excellent; and David Archer's University of Chicago climate class lectures (recommended by others; I haven't watched) are available online too.

New policy re climate contrarianism comments as of 11/11/2009:
Comments questioning the climate science community's understanding of climate change (97% of active climatologists now believe that the earth is currently warming and that it's human-caused - link) will be deleted unless the commenter:
a) is local
b) uses his real name
c) provides link(s) to substantiate his claim(s)/inference(s)
d) is willing to collaborate on constructing an argument tree, to get us past the usual sterile point-counterpoint-countercounterpoint.
(For people who can't read the above, a summary:
1) Be civil;
2) Don't post w/o giving at least a pseudonym;
3) Don't espouse climate-denial crankery unless you're local and willing to stand behind it.)
Caveats:
1. Comments could be delayed: they are being moderated, and I'm sometimes away from the computer for a day or more.
2. : Perfectly legitimate comments are sometimes miscategorized (by the blogging platform) as spam, & not published. If this happens to yours, please notify me, else I might not notice for a day or two.
