That is a wrong conclusion to reach. Another conclusion is that at some time those limestone deposits were much lower and plate tectonics has forced the plate upwards. There isn’t enough water on Earth to raise the sea levels another 100 feet.
” that at some time those limestone deposits were much lower and plate tectonics has forced the plate upwards.”
That is the wrong assertion to make.
There is no plate tectonic activity in FL since N.American plate separated from African place millions of years ago.
Ice melting raises sea level not ‘water on Earth’.
“if all of them were to melt, global sea level would rise approximately 70 meters (approximately 230 feet), flooding every coastal city on the planet.”
Plenty of ice left to raise sea levels.
