In a new study, over 13,000 islands were assessed for coastal change over the last three decades (1990-2020).
Only 12% of these islands experienced significant shoreline change during this period.
Only 12% of these islands experienced significant shoreline change during this period.
Thus, approximately 88% of the islands had stable coasts − neither substantial erosion nor accretion...
This is “contrary to initial assumptions.”
“Moreover, the data results suggest that sea-level rise has not been a widespread cause of erosion for island shorelines in the studied region.''...
“Contrary to initial assumptions, our empirical data does not conclusively link the widespread erosion of island shorelines primarily to historical sea-level rise, suggesting that human activities might mask the effects of sea-level rise.”...
