Pacific Climate Change Science Program is an intergovernmental research initiative providing coordinated climate change science for the Pacific Islands Forum region, linking scientific institutions across the Pacific Ocean, Australia, and partner countries. It delivers assessments, projections, and capacity-building focused on sea level rise, ocean warming, and extreme events to inform adaptation planning in the Republic of Fiji, Kingdom of Tonga, Independent State of Samoa, and other Pacific Island nations. The program integrates modeling, observations, and stakeholder engagement to support decision-making by regional entities such as the Secretariat of the Pacific Regional Environment Programme and the Pacific Community.
The initiative coordinates contributions from national agencies including the Commonwealth Scientific and Industrial Research Organisation, the Bureau of Meteorology (Australia), and research universities such as the University of the South Pacific, Australian National University, and The University of Auckland. It synthesizes outputs from global institutions like the Intergovernmental Panel on Climate Change and regional partners including the World Meteorological Organization and the United Nations Development Programme. By aligning capability across laboratories, observatories, and meteorological services, the program seeks to produce regionally relevant projections that account for influences from the El Niño–Southern Oscillation, the Pacific Decadal Oscillation, and remote forcings associated with the Indian Ocean Dipole.
Primary objectives include producing high-resolution sea level and climate projections, improving tide and ocean current monitoring, and translating scientific findings into actionable information for national adaptation planning. The scope covers low-lying atolls such as Funafuti and Tarawa, volcanic high islands like Viti Levu and Upolu, and the Exclusive Economic Zones of members including Papua New Guinea and the Cook Islands. The program emphasizes cross-cutting goals: enhancing observational networks (linking Pacific Tsunami Warning Center assets), advancing downscaled climate models used by groups such as SCRIPPS Institution of Oceanography, and strengthening regional modelling capacity at centers like the National Institute of Water and Atmospheric Research.
Governance typically involves steering committees composed of representatives from national meteorological services (e.g., Fiji Meteorological Service), regional bodies such as the Pacific Islands Forum Secretariat, and funding agencies like the Australian Department of Foreign Affairs and Trade and the European Union. Funding streams combine bilateral assistance from governments including New Zealand Ministry of Foreign Affairs and Trade and multilateral support from institutions such as the Green Climate Fund and the World Bank. Independent research institutions—CSIRO Ecosystem Sciences and the Commonwealth Scientific and Industrial Research Organisation divisions—receive contracts and grants to execute technical work, while oversight is coordinated with policy partners like the Secretariat of the Pacific Regional Environment Programme.
Core research themes include sea level change, coastal vulnerability, coral reef resilience, ocean acidification, and extreme weather attribution. Activities span installation of tide gauges and satellite altimetry validation with partners such as the European Space Agency and National Aeronautics and Space Administration, development of regional ocean models drawing on work at the Met Office Hadley Centre, and paleoclimate reconstructions using archives curated by the Australian National University and the Geological Survey of New Zealand. The program supports studies of climate drivers including interactions among the El Niño–Southern Oscillation, Southern Annular Mode, and local bathymetry effects around archipelagos like the Marshall Islands and Federated States of Micronesia. Capacity-building involves secondments to institutes such as the University of Hawaii and training with the Asia-Pacific Network for Global Change Research.
Stakeholders include national governments (e.g., Kiribati), non-governmental organizations like the Nature Conservancy and Conservation International, and regional technical agencies such as the Pacific Meteorological Council. Partnerships extend to research universities (including University of the South Pacific and University of Canterbury) and international research centers like the International Union for Conservation of Nature and the United Nations Framework Convention on Climate Change processes. Community-level engagement involves municipal councils on islands such as Alofi and Nukuʻalofa, traditional leadership structures and civil society groups that collaborate with donors including the Asian Development Bank on adaptation projects.
Major syntheses produced under the program provide region-specific projections of sea level rise, identifying higher-than-global-average local trends due to ocean dynamics near the Western Pacific Warm Pool. Reports highlight risks to freshwater lenses on atolls such as Tuvalu and project increased frequency of compound flooding during high tides coinciding with storm surges, as observed in studies referencing events like the Cyclone Pam impact on Vanuatu and flooding in Honiara. Findings emphasize coral bleaching linked to marine heatwaves similar to those documented by NOAA Coral Reef Watch and outline implications for fisheries important to Palau and Solomon Islands.
Outputs inform National Adaptation Plans submitted under the United Nations Framework Convention on Climate Change and guide infrastructure investments funded by the World Bank and Asian Development Bank. Science-to-policy translation supports land-use guidance, coastal setback standards in jurisdictions such as Cook Islands and Samoa, and disaster risk reduction strategies aligned with the Sendai Framework for Disaster Risk Reduction. The program’s work has catalyzed integration of sea level projection data into national planning by ministries such as the Fiji Ministry of Economy and influenced regional dialogues at forums including the Pacific Islands Forum Leaders Meeting.
