Nobel peace prize winner, former vice-president and climate crusader Al Gore gives a short (7 minutes) updated presentation on the state of our climate. Besides highlighting some of the latest climate science Gore also talks about the “clean coal” lie.

The video comes from a TED conference in February 2009. Watch it:

By now I guess everyone has seen Al Gore’s movie and slide show, or at least understands the severity of climate change.

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.
