> Other than displacing a large number of people who live on coastlines, what's the big deal?

"Other than that, how did you enjoy the play, Mrs. Lincoln?"

The displacement of large numbers of people will cause immense strife. Just look at the nasty reaction to the relatively small migration away from the Syrian civil war.

The problem is basically that all the land near populated coastlines is already owned, and those owners are not going to be inclined to let millions of their neighbors move in without some compensation.

But if those neighbors' coastal property just got swallowed by the sea, they probably don't have many assets left to pay.

Though the Syrian civil war can be used to illustrate this, a better example is the india - bangladesh fenced wall. Bangladesh is one of the first country and most severely impacted by climate change and this wall has been put in place to stop people bangladesh migrating away from climate change consequences into India.
