If you haven’t seen Al Gore’s movie about climate change “An Inconvenient Truth” because you’re not sure you could sit through a feature-length lecture/slide show given by a US politician, his TED lecture offers a less intimidating introduction to the man with the message for the world.

Beware, he’s likely to keep you riveted for a full 15 minutes and you won’t be the first person he’s converted to the cause.
