This research identifies and summarizes the latest peer-reviewed research related to the effects of climate change on Southeast Asia and Pacific Islands, drawing on both the literature summarized in the latest Intergovernmental Panel on Climate Change (IPCC) assessment reports and on other peer-reviewed research literature. It includes such impacts as sea-level rise, water supply and demand, agricultural shifts, ecological disruptions and species extinctions, infrastructure at risk from extreme weather events (severity and frequency), and disease patterns. The research addresses the extent to which Southeast Asia and Pacific Islands are vulnerable to climate change impacts. The timeframe of this analysis extends through 2030, although various studies referenced in this report have diverse timeframes and extend through the 21st century. The research also identifies (Annex B) deficiencies in climate change data that would enhance the IC understanding of potential impacts on Southeast Asia and Pacific Islands and other countries/regions of interest.
