Coming Soon...Waterworld

Last week a commenter pointed out Flood Maps which pairs NASA elevation data with Google Maps and show us the various lands we'd lose if the ocean were to raise a variable amount of meters. Worldchanging hit on this at the end of March:

For some people, global warming is a hard sell. Temperatures going up by a few degrees doesn't sound all that bad, and even results like drought or increased spread of mosquitos and other pests, while certainly unpleasant, are familiar issues. Mega-problems like whiplash/abrupt climate change, where warming leads to an ice age, can sound more surreal than threatening. But this website might change their minds. It shows something that is obviously warming-related, is already starting to happen (not just a "might happen 50 years down the road" possibility), and is a clear danger to the industrialized world's economies and societies: a seven meter rise in sea levels.

Above is a map showing that Harbor Island and huge portions of the waterfront and Duwamish valley would disappear if the sea level raised 6 meters. Expand this post to see way more maps than necessary of Salmon Bay and the locks.
