Many populated areas are about to become uninhabitable, and transport and supply chain infrastructure in and around them will be permanently broken.
Rising sea levels are much less of a problem than a constant series of rain bombs, storms, droughts, and fires.
When you get a Milton and/or a Helene every few years - or every year, or more than once a year - there's no practical way to rebuild, and insurance will be a distant memory.
The only reason most people don't know this is because extreme weather events around the world aren't making the news unless they're local-ish.
Hardly anyone in the US has heard about Acapulco after Otis, or the recent rain bomb storms in France, Spain, and Italy, or the flooding in Iran, or the fact that large areas of arable land in the UK are waterlogged and farmers are promising significantly smaller crop yields.
What I'm most worried about is how farming will adapt. Either food production needs to shift to geograhically new areas, or we'll need massive storm-proof greenhouses where hostile weather conditions don't matter. Large scale desalination of seawater will be likely needed too.
Given enough money, anything is possible of course. In my country we grow things like cucumber and tomatoes during winter in heated greenhouses with artificial light, even though it's dark and freezing outside. They just cost 2-3x more than same stuff produced further south.
In the long run it'd be a "good thing" for the survivors, but in the short term people won't just sit there while their environment grow hostile to their presence, and they'll try to move to a more livable environment, but those will be guarded by people already living there, with bullets and fences...
