Combine this with the current climate change model
that estimate 14.5 million¹ will die as a consequence
we can expect significant population reduction.
Sadly our western capitalist societies and probably the rest as well will collapse.
Our present arrangement is based on growth. As the population declines so does growth potential. (though that requires the market to be already saturated. If you are a new company creating a new widget that people want you will naturally see growth. If you are Apple much less so).

I believe most of the misery could be still avoided with massive amount of investment into green technology, AI and robotics to take care of the old and so on. But if Americans continue to elect people who hate science and have ideological love for fossil fuels, then we're probably doomed indeed.
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.
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.
