Will the US see large engineering works this century to prevent flooding? Large stretches of Florida have quite alot of property right on the sea barely above sea level, would these property owners demand protection?
There's probably not much chance of saving florida.
Is the wellwater seepage the biggest problem? Guessing the other things in the list could be fixed with lots of money and infrastructure.
So far, I've heard they have 100 years to sort it out. The "engineers" will find a "solution". They'll build dikes like the dutch (never mind the dutch took 300 years). My favourite is "we'll build houses on stilts".
