 Yeah, certainly sea level rise is already nibbling away at a number of islands. There's an island off the coast of Louisiana that is going to have to move, and they're in the process of trying to find the money to do it. A couple islands off the coast of Alaska, Kivalina, looks like they're going to have to move because of erosion problems due to rising seas. And that's going to continue to increase in coming decades. There's going to be a lot of trouble moving.
