2092 is the year where (I think) had sea levels raising, and Kiribati, Solomon Islands, Vanuatu, Tuvalu, and the Maldives being the only countries that were (maybe) sunken underwater completely. Florida (a US state) had lost most of it's land due to raising sea level. And the UFTM ceased to exist, as it's former members went on.
Anyways, pick a country of your chose (and I'll play too). Also, though you can pick one country, just like the Unstable World Map Game from Duckmapper (and I'll give credit to Duckmapper), you can mention a country (but not the countries that are underwater).
