Now that Al Gore's new movie, An Inconvenient Truth, is in the news and on the blogs and the real-life flood waters have receded, I thought this might be a good time to point out a couple of map tools that show what happens should the sea level rise. There's a fairly detailed tool from the University of Arizona Department of Geosciences that allows you to raise the sea level up to 6 meters with the danger areas highlighted in red. There's also a Google Maps mash-up that lets you drill down even further.
Just for fun, here is the future map of Watertown if the seas rise 14 meters (a mere 45 feet).
