I think the point was more that even if you're on a coast a lot of other problems are more likely to impact you first: higher energy and more frequent hurricanes, insurance, costs, etc.

It's not as a-vs-b as this. Rising sea levels will increase the damage of those more frequent hurricanes long before one's house falls into the sea. And that increases insurance costs, and so on. The whole thing is a single system with a giant feedback loop.

It could be an a vs b thing if a effectively finishes the conversation before b gets going.

A lot of areas won’t make sense to insure due to storm risk well before they’re at risk from literal sea level risk.

I suspect most islanders and coastal property dwellers will be wrecked by volatile weather first

There's a sweet spot where i will eventually have coastal property.

Temporarily...

I wonder if the dutch have a plan to evacuate the whole country in say, a year time, in case walling the seas no longer feasible?

Not in an emergency scenario but more like "it doesn't make sense to stay here anymore".

Why would it no longer be feasible?

I mean, I can tell you why. It's not feasible if it costs too much. If it makes sense (i.e. the land is worth X and cost of a wall is some fraction of X that people can afford) people will do it.

Or say, a country bordering Bangladesh. Sea rise of 1 meter would inundate 10% of Bangladesh, a country of 170M in 150,000 sq miles. I suspect a refugee crisis in Bangladesh would end in genocide…
