This Article discusses two inter-related issues: the legal implications of climate-induced migration and the phenomenon of _disappearing states through the lens of four case studies, Kivalina, Inuit, the Maldives, and Tuvalu. As early as 1990, the Intergovernmental Panel on Climate Change (IPCC) recognized that the greatest single impact of climate change may be on human migration. With sea level rise, Small Island States face the prospect of losing their territory. The Article discusses the challenges that these two issues pose for international law.
