The Pacific Islands Regional Mission serves Cook Islands, Fiji, Kiribati, Marshall Islands, Micronesia, Nauru, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu.

All 12 countries spread across the Southern Pacific Ocean face significant challenges from a changing climate. The region is vulnerable to events such as tropical storms, drought, and extreme rainfall, as well as longer term hardships related to sea level rise. Climate change also poses threats to the region’s tourism industry through impacts on coastal infrastructure, coral reefs, and coastal ecosystems.
