I found a bug. According to the map, if sea levels rise by 1 meter then both Death Valley and the Salton Sea will be completely flooded. But if there's a 0 meter sea level rise, they remain unflooded. I guess relying elevation maps does not give the whole story.

"Note: Some inland depressions, such as the Caspian Sea, show inundation on the map but would not be flooded. This is because the mapping algorithm is based upon elevation and can not distinguish areas that are separated from the oceans by a ridge or other high area. Be sure that you trace a connection with the ocean before assuming the area would be flooded. "

Doesn't look good for the Netherlands...

Well, at least part of the Netherlands (approx. 26%) are already below sea level. And it doesn't look that bad.

Netherlands is protected by dams. The solid geology of the area has allowed for durable dams to be constructed over centuries.

Places like Florida are going to be severely hit by rising sea levels because so much of the land is porous. You can't build a dam to stop the sea if it seeps in from underground.

Are there any predictions for the next X-years of how high the seas might rise?

In its most recent assessment report (2013), the IPCC predicts a sea level rise between 50cm and 1m by the end of the century with the CO2 emissions worst case scenario. In the best case scenario, it would be between 30 and 60 cm.
