KOROR, September 3 — Pacific island leaders gathered in Palau this week for a summit overshadowed by a grim United Nations assessment. A new report by the United Nations Environment Programme, released ahead of the meeting, warns that global temperatures could rise by up to 1.8 degrees Celsius above pre-industrial levels. That figure exceeds the Paris Agreement’s 1.5-degree target, and scientists at the summit said the overshoot will directly strike the economies, food security, and livelihoods of Pacific island nations.
Andrew Jones, Deputy Director-General of The Pacific Community, offered specific projections. Rising sea temperatures will push tuna eastward, he said.
Since about one-third of the world’s tuna is produced in the Pacific, this migration could cut fishing license revenue by approximately 90 million US dollars — about 13 percent of the total government revenue in the region. The damage would not remain abstract. Coastal fishing communities could see catches drop by about 65 percent.
That would eliminate a healthy protein source for roughly two meals per week per family, directly threatening food security across the region.
Existential Risks to Low-Lying Islands
Scientists also warned that climate change increases the risk of devastating floods. Saltwater intrusion into freshwater sources, they said, will make human settlement difficult on low-lying islands. Maina Talia, Climate Change Minister of Tuvalu, framed the crisis in present-tense terms.
The climate crisis is not a future problem but a reality that has already occurred, according to his account. Pacific island nations used the summit to press for concrete commitments.
They demanded more financial assistance for adaptation and specific steps from developed countries to reduce fossil fuel use. Tina Stege, Climate Envoy of the Marshall Islands, called for more immediate efforts to save the 1.5-degree target. Ralph Regenvanu, Climate Change Minister of Vanuatu, directed sharper criticism at Australia.
He accused the major Pacific member and large coal and gas exporter of not taking sufficient steps, and demanded it stop expanding fossil fuel exports. Australian Prime Minister Anthony Albanese defended his government’s position.
Transforming the country’s energy system to renewable energy will take time, he said. Gas will play a role in the transition. He added: “We all need to do more.” The summit’s outcome remains to be seen.
What is certain is that Pacific leaders have tied their demands to specific, quantifiable damages — and that the gap between their urgency and the measured pace of major emitter responses will define the region’s diplomatic agenda through the coming year.
