Unfortunately, unless we install some kind of back-stop to facilitate people moving without ruining themselves (since the median American has a little under half their net worth tied up in their home), this will be a messy transition. You can't sell those houses to afford to move elsewhere since the whole problem is they can't safely be houses anymore (as the sage said, "Sell them to who, Ben? F**ing Aquaman?").

We will all pay the tab to restructure society to avoid this climate change effect, or we won't and we can expect the people who get screwed to not be particularly invested in being part of this society.
