Sea level changes are not that much of a challenge. We have centuries of experience building infrastructure to manage that and decades more to leverage that. Much of the country is already below sea level and already well prepared for extreme water levels. Some of the infrastructure will need some upgrading of course. The reality of sea level changes is that they will be most devastating in places where they won't be able to pull together the economic resources to put infrastructure in place or where they are making the historic mistake of assuming it won't happen.

This is a myth. Despite the global warming, Dutch sea level rising has not accelerated. See e.g. https://www.clo.nl/en/indicators/en0229-sea-level-dutch-coas...

I was worried about that too, only it turns out that due to the exact location the risks due to the sea level are much lower than in other countries. Having the British Isles as a buffer from the Atlantic really helps.

Changes to the weather pattern (particularly the rain) are a bigger cause of concern.
