If sea levels do rise there are going to be quite a few overpopulated Indian and Pacific Ocean Islands that will be very hard pressed to keep their necks dry.

Practically that means those islanders will be going somewhere if their homes are drowned. If they come here they go on the doll immediately. Islanders' metabolism is notoriously terrible when it comes to the American diet. So we wind up with a new welfare baby population with all the health problems of obesity.

On the other side Venice and the Netherlands will be hardpressed if sealevels rise. Along the East Coast you will have a lot of beach errosion. Realistically there are quite a few people with expensive property along the intercoastal waterways. They are going to want insurance money, and the insurance companies are going to want a federal bailout.

Tennessee is too high up for ocean beach property. California isn't falling into the ocean.
