South Pacific Communities Threatened by Ocean Heat and Sea Level Rise
Updated June 5,2025
Island nations in the South-West Pacific face an existential threat from unprecedented ocean warming and rising sea levels,according to a new report from the World Meteorological Institution (WMO). The State of the Climate in the South-West Pacific 2024 Report,released Thursday,reveals record-high sea-surface temperatures and near-record ocean heat content across nearly 15.4 million square miles.
The report details how extreme heat and rainfall events in 2024 caused widespread devastation. The Philippines endured a record number of tropical cyclones, while Indonesia’s last tropical glacier in New Guinea edges closer to extinction. The climate change impacts are especially acute in island communities, where half the population lives near the coast.

WMO Secretary-General Celeste Saulo emphasized the urgency of the situation. “2024 was the warmest year on record in the South-West Pacific region.Ocean heat and acidification combined to inflict long-lasting damage to marine ecosystems and economies. Sea-level rise is an existential threat to entire island nations. it is increasingly evident that we are fast running out of time to turn the tide,” Saulo said.
Despite the grim outlook, the report highlights the value of strengthened early warning systems. In the Philippines, these systems helped communities prepare for typhoons in 2024, protecting lives and livelihoods. The WMO says this exemplifies the value of the Early Warnings for All initiative, even as 50,000 Pacific Islanders face potential displacement due to climate change.
The report also includes a case study of Fiji’s Serua Island, highlighting the cultural and spiritual challenges of relocating displaced communities with deep ancestral ties to the land.
“Villagers are running out of adaptation options, with the building of seawalls, plantation of mangroves, and improvement of drainage systems no longer being viable,” the report said.
What’s next
The report was released in conjunction with the Global Platform on Disaster Risk Reduction 2025 in Geneva and ahead of the 2025 UN Ocean Conference, underscoring the need for global action to address the escalating crisis in the south-West Pacific.
