Also, I have no faith in this new information altering public policy. Mostly politicians want to stave off change as long as possible. They have that power. They won't change unless forced to. As climate change is already upon us and we are long past the point where doing anything about it would mitigate the changes to bearable levels, continuing to fuck around will likely result in a "beyond all recognition" scenario.
Worth mentioning: impact of sea level rise depends primarily on two factors: total height above sea level and degree of slope. Nations with a low maximum height (the Maldives is just a few meters at most) and/or a very gradual slope will be largely or wholly inundated. Those whose coast consists of tall steep cliffs needn't worry on that point.
