Spread across the Pacific Ocean's vast expanse is a diverse array of countries with widely varying topographies, cultures, and economies, but who all share the same critical challenges and vulnerabilities. They face dire and immediate consequences from the impacts of climate change-from sea level rise and stronger storms to the changing distribution of disease vectors-that are markedly disproportionate to their mini scule contributions to global greenhouse gas emissions. Their geographic isolation, small and scattered populations, fragile environments and limited resources several restrict their capability to adapt to climate change's impacts.
