Two new warnings from Manila this week put the Pacific's vulnerability in sharp focus, and both matter if you're planning a trip to the region.
First, the World Health Organization says Pacific health systems are being squeezed from all sides. At the WHO Western Pacific regional meeting, regional director Dr Saia Ma'u Piukala revealed that seven Pacific island countries are among ten in the region yet to factor health into their national climate plans — despite being among the most exposed to climate risks. Warming temperatures are changing how diseases spread and displacing communities, while health services already battle noncommunicable diseases, which account for nearly 90 percent of deaths across the Western Pacific. Hypertension control rates sit below 10 percent in some Pacific areas.
Help is arriving in patches. Fiji and Kiribati are getting climate-resilience support through a partnership with Korea's KOICA, while Solomon Islands, Tuvalu and Vanuatu benefit from a WHO-UNDP project funded by the Global Environment Facility. WHO's accreditation by the Green Climate Fund should also open a direct financing channel for resilient hospitals and early-warning systems. There was one bright spot: the region could become the first to eliminate measles if countries hit 90 percent child vaccination coverage by 2029 — a big ask given 1.7 million children in the Western Pacific received no vaccines in 2025.
Second, the Asian Development Bank's Asia-Pacific Climate Report 2026 puts hard numbers on coastal risk. Annual flood damage across Asia and the Pacific, currently around US$27 billion, could hit US$172-199 billion by 2050, and as much as US$739 billion by 2100 without adaptation. Sea levels are projected to rise 20-35 centimetres by 2050, with some locations approaching a metre by 2100 under high emissions. More than 30 million people could face coastal flooding each year by mid-century.
For island nations the stakes are existential: reefs and fisheries that feed communities and shield coastlines are on the front line, and 124,000 Pacific women could be pushed into food insecurity by 2030. The ADB's counterpoint is that money spent now pays back hugely — US$9-19 billion a year in coastal protection could avoid US$178-360 billion in annual damage, a benefit up to 20 times the cost.
There's also diplomatic movement in the region. Israel has joined the Pacific Islands Forum as a development partner, a decision taken at the leaders' meeting in Palau that has drawn criticism in New Zealand, where the Labour opposition says Prime Minister Christopher Luxon has questions to answer — especially given his earlier statement that Israel's leader would face arrest under the ICC warrant if he entered the country.
Why should travellers care? Because the Pacific's appeal — healthy reefs, working clinics, resilient coastal towns — depends on the adaptation funding and planning these reports describe. If you're heading to Fiji, Kiribati, Vanuatu or Tuvalu, you're visiting places actively wrestling with how to stay liveable, and your tourism dollars feed directly into that equation. The ADB's own framing is blunt: coastal resilience isn't about stopping development, it's about making smart choices now so these communities can adapt and thrive.
