out of curiosity, what island nations have been submerged ?
Other links were mostly "could","will","may" etc.

That's just off the top of my head
> In addition, because the sea level is rising on the islands, Tuvaluans must continually deal with their homes flooding, as well as soil salination.
> Soil salination is a problem because it is making it difficult to get clean drinking water and is harming crops as they cannot grow with the saltier water. As a result, the country is becoming more and more dependent on foreign imports.
> Tuvalu has adopted a national plan of action as the observable transformations over the last ten to fifteen years show Tuvaluans that there have been changes to the sea levels. These include sea water bubbling up through the porous coral rock to form pools at high tide and the flooding of low-lying areas including the airport during spring tides and king tides.
Re: land increase
2% is within the margin of error and experts have raised issues about the accuracy of data collected prior to 1993.

It is also understood that growing coral reefs combat sea level rises to an extent, but that this biological mechanism is not infallible.
In any case, the rising sea levels are a matter of fact :
> The 2011 report of the Pacific Climate Change Science Program published by the Australian Government,[297] concludes: "The sea-level rise near Tuvalu measured by satellite altimeters since 1993 is about 5 mm (0.2 in) per year."
Lastly, there is no meaningful difference in this context between a completely submerged island and an island that is in the process of becoming submerged by the sea. You are arguing a moot point.
Our peaceful and sustainable coexistence with the rest of the world (natural or otherwise) has always required the curtailment of some liberties.
You cannot sell tubercular beef and poison the population. For the same reason, you cannot submerge island nations and cause droughts that make other regions of the world inhabitable. Deal with it.
