【Abstract】

For 30 years, international concern has been expressed about the effects of global warming and the need to strengthen countermeasures has been confirmed. However, as of 2019, the World Meteorological Organization (WMO) reports that temperature increases due to greenhouse gases have not been halted and that sea level rise due to climate change is also accelerating. The Intergovernmental Panel on Climate Change (IPCC) accepted the 1.5°C Special Report in October 2018 and further adopted the report's Summary for Policymakers. There is now a focus on how these scientific findings will be reflected in national policies, as well as in the context of maritime policy, and the decisions of national policy makers on climate change.
Since both New Zealand and Australia are maritime nations with deep ties to Pacific island nations and are facing the problem of environmental refugees due to sea level rise and extreme weather events, we would like to introduce their climate change policies in the light of relevant international trends and present a certain assessment focusing on migration issues.
