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 yearDr. Virginie Duvatpublished aglobal assessmentof 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…
