The US government must fund "managed" retreat from housing that is doomed to be flooded or burnt.

The people who live in those homes can't afford to move or build elsewhere — the government must help them. But subsidizing rebuilding in place is an enormously inefficient way to do that.

I disagree with the statement that "managed retreat is not defeat." Of course it is! Global heating disaster will be one defeat after another. However, there are different kinds of defeats. When you can't win the battle, an orderly retreat is much less bad than a disorderly rout, and that's what will happen if we don't plan this.
