What Could Disappear

The New York Times recently put out these interactive maps showing what areas of various US cities could disappear from rising sea levels if they are not protected. The page is a bit alarmist because the map defaults to the most extreme scenario - a 25 foot sea level rise. This is the "potential level in coming centuries" not the "probable level in about 100 to 300 years." In the extreme view you can say goodbye to Miami, New Orleans, Norfolk, Atlantic City, and most of Souf Philly, Cambridge, Mass. and Charleston:

The 5 foot rise view gives a more realistic picture of what to expect in the coming century. This also gives a good picture of areas likely to flood in an extreme storm event. Here are some examples:

Miami looks mostly OK but Miami Beach is 94% gone and the western suburbs are also looking wet.
New Orleans is in trouble again. In fact the 5 foot model is not much better than the 25 foot (88% flooded in the city and surrounding areas in the next 100 to 300 years.)

Houston is dry but 68% of Galveston is under water.
Here's an animation I created for Savannah from present to the extreme followed by a side by side comparison between the 5 foot model and the 25 foot model.
