There's absolute consensus among all scientists that AGW is happening (consensus science is a foundational precept of all scientific endeavors i.e. world is flat, the sun revolves around the Earth yada yada yada), will get worse and the seas will inevitably rise and there's nothing we can do about it unless 2/3's of the population is culled and the rest return to gathering pre-historic existence.
With that said, this is what the models (all confirmed BTW, 100% accurate) show for how Barry "murderer of brown people" Obama's house will look by 2100 . . . so grand kids, you'll have to move to the mountains.
