Details:
Relatively recently (bug #17105), global catastrophes started causing terrain
conversion between land and sea -- for instance, global warming can cause land
tiles to turn into ocean.
However, this process takes no account of the surrounding terrain, so you can
end up with a single tile of ocean in the middle of a continent.
The attached autogame screenshots show the result. In this game, two AIs
ended up in a dumb stalemate until 3227 CE (perhaps due to bug #17661), with
many cycles of global warming; the world ended up as a series of perforated
archipelagos.
Perhaps these terrain conversions should be subject to the same rules as
human-initiated conversions, where a certain number of surrounding water tiles
are needed for a tile to become a water tile (and vice versa --
ocean_reclaim_requirement etc)?
That would have the direct effect of flooding coastlines, and the indirect
effect that land reclaimed from the ocean would tend to be more liable to
flooding.
If no-one objects, I'll probably look at this at some point.
