This new documentary on Showtime is pretty good (despite the appearance of Thomas Friedman), and this is the premiere episode.
One of the most interesting aspects of the show is that it emphasizes economic issues. The standard tactic of the climate change denialists is to argue that it’s happening, we can’t do anything about it, and it would hurt our economy to take measures to reduce emissions; but this show focuses strongly on the fact that climate change is doing us economic harm right now.
The denialists are, of course, squinking furiously against it already, but they lie. They lie hard.
By the way, Harrison Ford, one of the sponsors/narrator of the show, has also done an IAmA on Reddit lately — he seems to be a cool and admirable dude.
