The question of global warming is answered: It is happening and by 2100 lots of shit will be flooded like a mofo.

My advice
If you are under 40 look for a place 500 feet above sea level you should be fine at that level.
Lots of the world is 200 feet or more above sea level.Which would likely be fine.
You're too pessimistic.
https://earthobservatory.nasa.gov/images/148494/anticipating-future-sea-levelsThat growing knowledge base is why scientific organizations like the Intergovernmental Panel on Climate Change (IPCC) are publishing sea level rise projections with increasing levels of confidence.
In its 2019 report, the IPCC projected (chart above) 0.6 to 1.1 meters (1 to 3 feet) of global sea level rise by 2100 (or about 15 millimeters per year) if greenhouse gas emissions remain at high rates (RCP8.5).
I don't see rich people abandoning the Hamptons and Martha's Vineyard...
2019 data is old.
newer data is more like 10 feet by 2100.
For me it is fairly abstract as I have no descendants to worry or care about and I will be 99 in 2100.
If I were 30 with a few kids I would not live 10 miles from the Jersey shore at 66 feet above sea level.
I would move to upstate New York near lake George.

As for Hamptons it will be fucked by 2100
not so sure about Martha's vineyard as I do not know how it is sturctured. ie a sand bar like Hamptons is costly to dike vs a circle shaped island.
the Hamptons would need 3 sea walls to save.
much like the jersey shore. which is a series of sand bars.
they need 2 dikes 100 miles long and 30-50 feet high.
to save a 2 mile wide island .
and a third dike on the actual continent part of NJ.
If you study NJ you realize they have planned to use the NJ parkway for the dike so anything on the east side of it is fucked.
I have designed a few hundred speculative how to save the USA from flooding maps
If you look below and see my NJ plan and trace out the elevation maps or the heights of the GSP you will see this shit is planned for on many places in the world.
I live in NJ and plan to stay here at the moment I am on the good side of the GSP and will stay there.
I have heard that shit since the early 80s, and absolutely nothing have come true. The university of Lund measures the sea level every year, and it still rises within the same 1-3mm that it has done since forever.
