Polar Ice Melting Faster than Thought, at frightening rate, from Paul Beckwith

I've written more than enough to introduce climatologist Paul Beckwith, and anyone can learn far more than that from his website, paulbeckwith.net.

But to conform to the guidelines here, I'll at least say that this is about the major ice melts and rising oceans, caused by unexpected ice melts recently observed via NASA. This one is particularly focused on the Antarctic, but covers the North Pole too.

It is a two part presentation, at Paul's standard 15 minutes, and the second part automatically follows (at least on my computer, you may have to search for yourself if this doesn't happen, or just visit Paul's website).
