That's my understanding ... sea level rise is due mostly to thermal expansion, and not so much ice melt ... the confusion comes from so much ice is melting, except this is sea ice, and melting here doesn't effect sea level (much) ...
The problems in Florida are due to ground water pumping ... and the ground is subsiding far quicker than sea levels are rising ... same in Louisiana and California's San Joaquin Valley ...
Phaw ... if Florida isn't worth it ... don't bother with sea walls ... maybe only Japan deserves to survive because
they build sea walls ...
"Around 350 kilometers of seawalls have been built since 2011 — with another 80 kilometers under construction — at a budget of ¥1.3 trillion (roughly $12 billion). Designed to protect Tohoku from any future tsunamis, these gray giants are at once visually striking and, to me, horrific eyesores that seem engineered to erase the existence of the sea."
