The reality is that the reef islands that are formed on living coral arcs or atolls are not a suitable long-term habitat for anything other than a very light human footprint: in the not-so-distant past, limitation was placed on population growth by the size of the freshwater lens that forms by the accumulation of rainwater in the compacted sand behind the beach, and above sea level. If this becomes exhausted by the withdrawal of too much water for drinking or for growing vegetables, the human population dies out, or must migrate.

IOW - overpopulation of these atolls is the primary cause of any distress they may incur in the future. Rising seas are a secondary concern.
