Now Al Gore has updated his slide show and "presents evidence that the pace of climate change may be even worse than scientists were recently predicting, and challenges us to act with a sense of "generational mission" -- the kind of feeling that brought forth the civil rights movement -- to set it right."
You can see his presentation of the new slide show over at TED (or after the jump). The video is 27 minutes long but worth every second of your time.
