NASA Time Machine

The NASA site has some really nifty features, and one of them is a Climate Time Machine interactive feature. You can see the effects of different sea levels on the Southeastern United States, you can track ice melt in the Arctic, look at what nations have reduced CO2 emissions (hint, the US isn't one of them) and get a look at global temperatures over time. The latter one is a little bit scary. There is kind of a little peak at the poles on the 1940's, but then things calm down a bit. This is what things looked like in 1965.

Things start getting bad around 2000, and this is 2007. Yikes.
