4 New Papers, One Alarm-Dispelling Conclusion: Future Sea Level Rise May NOT Threaten Islands After All

By Kenneth Richard on 4. November 2019
 
As reported in 4 separately-published papers, scientists have discovered a mechanism whereby islands can build themselves up naturally, thwarting the threat of sea level rise.  Tuck et al. (2019) affirm the “implications of island building are profound, as it will offset existing scenarios of dramatic increases in island flooding.”

Earlier this year, Duvat (2019) identified a global trend in island shoreline net growth despite recent sea level rise.

The welcome news is that none of the islands larger than 10 ha – and just 1.2% of the 334 islands larger than 5 ha – have decreased in size since the 1980s. Nearly 90% of the world’s islands have been stable to expanding in coastal area during recent decades.

Coral will grow to remain in the photic zone, which is why many tropical volcanic islands have substantial reefs offshore. As sea level rises (should it do so), the coral will keep up if at all possible and grow to where it can function optimally. If sea level drops, wave action will erode existing reef structures, often infilling lagoons with debris and sediment, and coral will grow in what was deeper water, expanding the ring of coral around the island.
Life finds a way, and nature adjusts.

Weren't the Maldives supposed to be under water, literally, by now?
