> We're going to rack up unbelievable debt trying to either migrate people out of flood zones or try to delay their immersion. I've said before that once Miami starts flooding enough that people can no longer stick their heads in the sand and pretend nothing is wrong, Florida real estate owners will probably demand some ultra-expensive engineering megaproject to try and save the city on the taxpayers' dime.

I agree, but how many years away is that scenario? 100 years? `Wikipedia has a few predictions in https://en.wikipedia.org/wiki/Sea_level_rise#21st_century but most of them predict something between 1ft and 4ft. (Unless there is a catastrophic event.)

I guess it's not enough to drown Miami, but it may change the coastline. Anyway most people investment is not thinking about 100 years in the future, and I never understood why people invest in an area that is heavy in hurricanes (even in normal climate).
