re: #101 LudwigVanQuixote
We’re already seeing this with, for example, India and the fence they are building around Bangladesh.
The stronger country is trying to insulate themselves from the smaller country whose population has a significant fraction (something like 20%) that leave at or near current sea level.
While the fence construction was started not as an adaptation measure to AGW, it will nevertheless come in very handy throughout the 21st century as Bangladesh deals with sea level rises.
