Atlantic City and other parts of the New Jersey coast are being inundated by sea level rise due to global heating.

Slightly higher costal areas, owned by rich people and businesses are getting seawalls to protect them for some more decades. The lower-lying poor people's houses are being left unprotected.

While in one sense that is unfair, it may necessary; sea walls could not protect the low-lying homes for many more decades. It might be better to buy them out.
