This paper points out that the exposure to climate hazards varies between states based both on geographical factors (such as the propensity to experience cyclones and droughts, island types and topography) and on such factors as population and infrastructure distribution, all of which provide a framework for considering regional vulnerability to climate change.
This report focuses on marine/coastal inundation and sea level and how they are affected by climate change.
The region of interest is the Pacific Islands, with a focus on Commonwealth countries (Fiji, Kiribati, Nauru, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu).
Pacific Island Commonwealth Member States (Pacific CMSs) are highly vulnerable to climate change (high confidence; robust evidence, high agreement). Impacts of climate change on extreme events relevant to Pacific CMSs vary, dependent on the magnitude, frequency, and temporal and spatial extent of the event, as well as on the biophysical nature of the island and its social, economic, and political setting (high confidence).
