“Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea-level rise. 88.6% of islands were either stable or increased in area, while only 11.4% contracted. It is noteworthy that no island larger than 10 ha decreased in size. These results show that atoll and island areal stability is a global trend, whatever the rate of sea-level rise.”- Duvat, 2019

Satellite observations indicate there has been 13,565 km2 of net growth in land area across the globe’s coasts between 1985-2015.
