If you haven't seen it, get yourself to a video store tomorrow. Then read the debate about whether the National Science Teachers Association should accept 50,000 free DVD's [What's up NSTA?].
I don't agree with PZ on this one. The science is good but Al Gore is exploring the possibility of a run for the Democratic nomination in 2008. I saw him in action for three days at Chautauqua last summer. If it were Carl Sagan I'd say NSTA should show the DVDs in every classroom but it's silly to pretend that Al Gore isn't a politician.
