“Until a few years ago, we were discussing whether it would happen at all, as a kind of low-probability, high-impact risk,” Rahmstorf told CNN. “And now it looks a lot more likely than just a few years ago that this will happen. Now people are starting to close in on when it will happen.”
No matter the political direction, much of Florida will be regularly flooded by sturm surges due to intensifying hurricane seasons. And while it might not happen during our lifetimes, the loss of most of Florida’s landmass due to rising sea-levels is pretty much locked in already, and the early effects of that on flooding and salt-intrusion into the groundwater will be noticable much earlier for sure.
In addition heatwaves will turn into deadly heat-domes in most of the south-east of the US within a relatively short time-frame, making survival dependant on the stability of the electricity grid to run ACs.
Housing prices will also collapse as a result of that and difficulties to find insurance, so more and more people will be stuck with property they can’t sell. Basically the longer you wait the harder it will get to leave in a way that doesn’t make you a climate refugee.
