Stone Age settlement found under the sea in Denmark

> As today’s world faces rising sea levels driven by climate change, the researchers hope to shed light on how Stone Age societies adapted to shifting coastlines more than eight millennia ago.

Unfortunately I don't expect there is any particularly reusable solution to be uncovered. Ancient peoples facing rising tides almost certainly just walked a bit inland and built new huts there. They probably thought nothing of it. They were a far more physically mobile culture, without great dependence on immense, immovable infrastructure - nor on rigid land ownership rules.

Our culture's migration will be entirely different.

I think the rigidity of land ownership will be put to the test because of climate change.

How much of other people's tax dollars do you expect to spend to safeguard the bad purchases of land (soon to be water) owners?

Rising sea levels aren't new, it's ancient. Buying coastal properties always carries risk.

Society at large should not have to keep bailing out people who make poor decisions like this.
