Abstract: "...The effects of climate change on Oceania, particularly rising seas, may significantly impact coastal populations and increase migration in the future, as the Asian Development Bank (ADB) and the Intergovernmental Panel on Climate Change (IPCC) have reported. Rising temperatures and declining rainfall may also contribute to lower yields from fisheries and agriculture, and a significant decrease in coral reef cover. Extreme weather events, including higher temperatures, wind, and rainfall, have already increased in number and intensity across the region. In the majority of Pacific island nations, of those who migrate, more people leave than come, according to the African, Caribbean, and Pacific Observatory on Migration. The majority of migration in the region is economically driven. In the future, climate change may further impact these migration patterns across the region, according to the IPCC. Climate change has already exacerbated challenges that aid-dependent nations in the region face, restricting livelihoods and resources and contributing to pressures to migrate. The costs of climate change, including a decline in crop yields, a rise in energy demands, and a loss of coastal land, are predicted to be significant. The ADB estimates these costs will reach 12.7 percent of the Pacific regions’ GDP by 2100. Increased migration may also impact political stability and play a role in geopolitical rivalries within the region, according to the IPCC. The effects of climate change, especially rising sea levels, may result in forced migration from the Republic of the Marshall Islands (the Marshall Islands) and have additional impacts on the U.S. defense infrastructure on the islands..."
