What is the first country predicted to become completely submerged due to rising sea levels? What are the odd of Tasmania becoming submerged? Why?

Under the most extreme climate change scenarios sea levels could rise by as much as 4-6 m by 2100. When sea level rises by, let say 5 m, that means anything less than 5 m above sea level at the moment will be underwater. The first place to become completely submerged will be the country with the lowest maximum elevation above sea level. That happens to be the Maldives, which has maximum elevation of only 1.8 m! That could be submerged by even low to intermediate climate scenarios.

Luckily for Tasmania, it has lots of mountains, meaning most of the state well above sea level. The high point in Tasmania (mt. Ossa) is 1,617 m above sea level. Even the most extreme sea level rise projection don’t come close to reaching that, so there is a near 0% chance Tasmania becomes completely submerged. Although towns, homes, and ecosystems on the coast, near the beach, could definitely run into trouble!
