Visualizing Rising Sea Levels

Yesterday I read a story in which is was reported that sea levels were expected [to rise at least 5 feet within the next 100 years](http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2009/03/11/MNTK16DEBF.DTL&type=green&tsp=1). A scary thought, but it is still really hard to conceptualize what that actually means, until of course, I stumbled upon a Google Maps mash-up which allows users to [visualize what would happen if sea levels rose](http://flood.firetree.net/?ll=43.3251,-101.6015&z=13&m=7) anywhere between one and fifteen meters.
I live in Oakland, so naturally the first thing I did was check out my city to see what it would look like. Luckily sea levels would have to rise considerably for my house to become beach-front property. But the [rest of Oakland is not so lucky](http://flood.firetree.net/?ll=37.8194,-122.2956&z=2&m=2&t=1).

The Bay Area would be pretty devastated. In fact it makes\ me wonder we would have to begin building levees as New Orleans has had to do – being a city that would live below sea level and all.
Here is what a couple of other cities in the United States might look like if sea levels rose just 5 feet (2 meters):
* [New Orleans](http://flood.firetree.net/?ll=29.9645,-90.0783&z=5&m=2)
* [Manhattan](http://flood.firetree.net/?ll=40.7655,-73.9840&z=4&m=2)
*Update: MSNBC has a post covering [the costs California will face](http://www.msnbc.msn.com/id/29656274/) if sea levels rise 5 feet.*
