A piece in the familiar public radio style. It uses a recent Hollywood release to jumpstart a discussion of global warming. Some of the information is worrisome, scary and should make you sit up and listen -- the ocean's level increasing quickly, polar icecaps and glaciers melting. I think the piece could have felt a little more urgent, but since that would require more slant, I applaud the relative objectivity of the producer. Timely for Earth Day, if the reference to "The Day After Tomorrow" is removed, and during discussions of global warming or green house effect or the Kyoto Treaty.
