I Never know quite what to believe about sea level rise.
I think the sort of Official number now is 1 foot in the next 30 years or so.

But I keep seeing these scary articles about Antarctic ICE shelves collapsing etc.. acceleration of this and that.

IMO just plan on 5 tp 10 foot rise over the next 20 years then don’t buy anything unless it 20-30 foot above that (just kidding sort of).
