This report warns that unprecedented ocean warming, sea level rise, and extreme weather are endangering lives, ecosystems, and economies across the region – especially in coastal and island communities. 2024 saw record sea-surface temperatures and near-record ocean heat content, with marine heatwaves affecting over 10% of the global ocean. On land, extreme heat, intense rainfall, and a historic cyclone season caused devastating impacts, while Indonesia’s last tropical glacier nears extinction.

The report highlights the importance of strengthened early warning systems, featuring success stories from the Philippines and Fiji that demonstrate how anticipatory action and community-led responses can protect lives and preserve cultural heritage. It calls for urgent investment in adaptation, early warnings, and climate-resilient development.
