Patterns of island change and persistence offer alternate adaptation pathways for atoll nations.

摘要: Sea-level rise and climatic change threaten the existence of atoll nations. Inundation erosion are expected to render islands uninhabitable over next century, forcing human migration. Here we present analysis shoreline in all 101 Pacific nation Tuvalu. Using remotely sensed data, is analysed past four decades, a period when local sea level has risen at twice global average (~3.90 ± 0.4 mm.yr−1). Results highlight net increase land area Tuvalu 73.5 ha (2.9%), despite sea-level rise, eight nine atolls. Island lacked uniformity with 74% increasing 27% decreasing size. challenge perceptions island loss, showing dynamic features that will persist as sites for habitation presenting alternate opportunities adaptation embrace heterogeneity types their dynamics.
