Climate Change Law and Marine Ecosystems: Legal Frameworks for Ocean Protection in a Changing Climate

Climate change has emerged as one of the most significant environmental threats affecting marine ecosystems in the contemporary era. Increasing ocean temperatures, rising sea levels, ocean acidification, and the growing frequency of extreme climatic events are profoundly altering marine biodiversity and coastal environments worldwide. Legal frameworks operating at both international and domestic levels play a fundamental role in addressing these challenges by regulating environmental protection, greenhouse gas mitigation, and sustainable ocean governance. This study examines the relationship between climate change law and the protection of marine ecosystems. It evaluates existing legal instruments, policy strategies, and governance mechanisms designed to mitigate climate-related impacts and safeguard ocean biodiversity. The research argues that stronger climate legislation, integrated ocean governance, and enhanced international cooperation are essential for preserving marine ecosystems and ensuring long-term environmental sustainability.
