David Thornalley, a professor of ocean and climate science at University College London, previously told Newsweek that the most vulnerable ice sheets are those in the Antarctic that are marine-based.

According to projections by the National Oceanic and Atmospheric Administration, assuming the IPCC’s worst-case scenario comes true, the Carolinas, Florida and Louisiana would likely be the worst affected states.

In Florida, Much of the Keys would disappear, all of Monroe County would be gone, and the coastlines around Cape Coral, St. Petersburg and Tampa would retreat significantly.

Much of Louisiana’s low-lying coastline would recede, and New Orleans would be connected to the mainland only via a thin strip of land running along the Mississippi River.

Overall, the Atlantic coast is predicted to fare far worse than the Pacific because of the more mountainous terrain in the West, although all coastal areas would recede.

A 2013 analysis by National Geographic suggested that if all the world’s ice sheets melted, the entirety of Florida would disappear underwater, as well as most of Louisiana and large portions of the Carolinas and Virginia.
