Indeed cities of mediterranean and baltic seas are luck to be able to escape raising sea levels by building on dam. But the sea level doesn't rise fast enough to motivate enough people to build a dam, so people will end up slowly leaving places that get inundated. But there is another way to prevent raising sea levels, which is moving that water into aquifers and lakes in places that are currently deserts. Huge deserts in Sahara Iran and Middle Asia can easily take the large chunk of water that is currently stored in polar caps. We just need to invest more in building large scale climate modifying structures, like solar towers, solar power plants, dams and canals.
