Global Responsibility to the Sovereignty of Sinking Island States Due to Climate Change: A Study in a Cosmopolitan Law

Sinking Island States represent a tangible manifestation of the impacts caused by climate change. According to Article 1 of the Montevideo Convention of 1933, these states face the threat of losing their sovereignty due to not meeting the territorial requirements outlined in the convention due to sea level rise. Given that this phenomenon arises from the collective actions of countries worldwide concerning climate change, this issue must be elevated to a global issue and addressed collectively. By adopting a cosmopolitan law approach, this research seeks to analyze how the international community can collaboratively overcome this challenge through sustainable recognition and efforts such as the creation of new international legal instruments, the initiation of artificial islands, land acquisition, and the establishment of ex-situ states in accordance with the cosmopolitan law approach. The research method employed is normative juridical and comparative studies among Sinking Island States. Utilizing data collection through a literature review, this study aims to identify cosmopolitan laws that can guide the formation of a global legal framework to protect the sovereignty of Sinking Island States.
