If the worst climate change predictions come true, hundreds of coastal US towns and cities - from Atlantic City, New Jersey, to Galveston, Texas - could disappear under water by 2100.

The National Oceanic and Atmosphere Agency released a report in January that hinted at the possibility of an "extreme" sea-level rise scenario that could cause chronic flooding to affect as many as 670 coastal communities. That scenario is considered unlikely, but possible.

Research group Climate Central took the projections laid out in NOAA's report and created a plug-in for Google Earth that shows how catastrophic the damage would be if the flooding happened today. You can install it (directions here) and see anywhere in the US.
