Climate Change and Biodiversity Loss in Island Ecosystems

Island ecosystems represent some of the most biodiverse yet vulnerable habitats on Earth. This study examines the cascading effects of climate change on endemic species across 47 Pacific island ecosystems between 2010 and 2024. Using remote sensing data combined with field observations, we document significant shifts in species distribution patterns, with 73% of monitored endemic species showing measurable range contractions. Our findings suggest that rising sea temperatures and increased storm frequency are the primary drivers of biodiversity loss, with coral reef degradation serving as a key indicator of broader ecosystem collapse. These results highlight the urgent need for targeted conservation strategies specifically designed for island biogeography contexts.
