As storms become more frequent and intense, sea levels rise, and coral reefs are destroyed, Pacific Islanders must adapt to a changing climate or move their lives elsewhere. Pacific Islands Countries (PICs) are at the forefront of climate change impacts and in the vanguard at international climate change negotiations. Yet, they still require improved access to financing to adapt to the threats of climate change. A central problem is that the climate finance architecture is in its infancy. And, it is changing; the Green Climate Fund started its work this year, and it is unclear whether it will replace or complement existing funds. It is therefore important for PICs and international actors to learn best practices from states like Samoa, who are succeeding in accessing funding from each global climate finance mechanism.
