Al Gore is back with global warming slide show 2.0

The folks at TED have posted a new video of Al Gore debuting his latest climate-change slide show, updated from the one he toured with in 2006's "An Inconvenient Truth." (He said he presented the old slide show about 2,000 times.)

"In order to solve the climate crisis, we have to solve the democracy crisis," he says, before restating his point from "Truth" that all the technology and know-how necessary to solve the climate crisis is already available. 

Gore's slide show, as before, features sobering images and analysis. How about the fact that the part of Antarctica that's melting is the size of California? Or that in 2005, we blew 6.2 tons of carbon dioxide into the atmosphere -- as an animation in the video illustrates, that's the weight of 1.2 billion elephants.
