Book excerpt: Several low-lying atoll island states are at risk of losing their entire territory due to climate change-induced sea level rise. In Disappearing Island States in International Law, Jenny Grote Stoutenburg examines the most relevant and pressing international legal questions facing threatened island states: at which point would a sovereign state disappear? Who could make that determination? Which legal status would its citizens have? What would happen to the state’s maritime entitlements and its international rights and obligations? Does international law protect the international legal personality of states that lose their effective statehood for reasons beyond their control? In answering these questions, the book goes to the root of a fundamental problem of international law: the nature of statehood.
