good news - The Maldives are not drowning"
Dec 23^rd, 2020 at 2:02pm

Despite sea level rise, a 2019 global analysis (Duvat, 2019) found 89% of 709 island coasts have been either stable or growing in size in recent decades. A new Maldives-only study (Duvat, 2020) finds rapid (>3 to >50%) coastal growth in 110 of 186 Maldives islands from 2005 to 2016. Just 5 islands – 2.7% – actually contracted in size during this period.

Last year Dr. Virginie Duvat published a global assessment of how the Earth’s islands and atolls are faring against the ongoing challenge of sea level rise since satellite monitoring began in the 1980s.

Fortunately she found “no widespread sign of physical destabilization in the face of sea-level rise.” In fact, a) none of the 30 atolls analyzed lost land area, b) 88.6% of the 709 islands studied were either stable or increased in area, c) no island larger than 10 hectare (ha) decreased in size, and d) only 4 of 334 islands (1.2%) larger than 5 ha had decreased in size."

And this -

"The impact of global environmental change on coral reef islands is uncertain with few studies having resolved the critical controls on island formation and change. Based on detailed, topographic surveys, sediment analysis and radiometric dating, we present a multi-phase model of the formation of a large inhabited reef island in the central Indian Ocean in response to Holocene sea level dynamics and transformations in reef development and reef ecology. The initial phase of island building occurred later than elsewhere reported in the Maldives, 2500–2100 years ago during the mid-Holocene sea level highstand. The island was able to support habitation shortly thereafter. Subsequent island expansion occurred as a consequence of relative sea-level fall and emergence of the reef platform that forced a transition in reef flat ecology and dominant sediment producers that contributed to island accumulation to the southwest. Small-scale sea level oscillations (± 0.8 m) over the past two millennia have driven periods of island accumulation, that intermittently reactivate geomorphic processes around the island shoreline. Significantly, the multiple phases of island development have occurred while the island has been continuously inhabited, demonstrating the adaptive capacity of the island community to multiple phases of change. Results highlight the complexity of reef island development and indicate that future physical trajectories will vary depending on not only relative sea level change, but how such changes modify water depth and wave regimes across reef surfaces, and changes in dominant sediment producers able to contribute to island building. This interrelationship differs between sites within and between reef regions and may account for currently expanding islands on reef surfaces."
