Abstract
Marine ecosystems are highly sensitive to climate change, with rising temperatures, ocean acidification, and changing currents affecting biodiversity. This article critically reviews the impact of climate change on marine species and habitats, highlighting the most vulnerable ecosystems, such as coral reefs and polar regions. It also explores the potential for species adaptation and the role of human intervention in mitigating these effects. The paper emphasizes the importance of international cooperation and policy changes to protect marine biodiversity, outlining strategies for conservation and sustainable resource management in the face of a changing climate.
