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.

yeah, weve got even better technology, itll be even less of a hassle

I’m not sure the people who own property next to ‘at risk’ coastlines will agree. As a whole, society may continue but there’s a lot of people at risk of losing their property as a result of rising sea levels. Probably decades from now.
