Pacific climate and food security warning: At the Pacific Islands Forum in Palau, leaders heard that overshooting 1.5°C could cut tuna access fees by up to US$90m a year and reduce coastal catches by as much as 65%, threatening nutrition and government revenue. El Niño and health risks: A new outlook warns El Niño is likely to continue through late 2026, bringing mixed drought and heavy rain patterns that could strain drinking water, food supplies, and children’s health—especially where fuel shortages are already worsening conditions. Dengue surveillance signal in the region: Hawaiʻi’s health department reported dengue virus detected in Hilo wastewater, with no active cases tracked; the finding is treated as an early warning, and dengue is noted as a year-round risk across parts of the Pacific including the Marshall Islands. Regional health cooperation at PIF: The Philippines used the forum to push deeper Pacific ties, including practical cooperation in health, disaster preparedness, and capacity building—areas relevant to island health systems. US support with health-adjacent priorities: The US announced over US$150m for Pacific initiatives, including hospital upgrades and drinking-water testing/cleaning support for Palau, plus broader energy and security funding that can affect health outcomes. Taiwan–Marshall Islands health-linked projects: Taiwan and its Pacific allies, including the Marshall Islands, signed a joint statement and highlighted Taiwan-funded work such as an AI system at Belau National Hospital and energy initiatives.
