Understanding Sea Level Rise: Projections, Impacts, and What We Must Do Sea level rise is one of the most pressing environmental challenges of the 21st century, with far-reaching consequences for coastal communities, ecosystems, and global economies. As climate change accelerates due to rising greenhouse gas emissions, understanding the current and projected sea level rise amounts becomes essential for policymakers, scientists, and citizens alike. ### What Is Sea Level Rise? Sea level rise refers to the gradual increase in the global average height of the world’s oceans. This phenomenon is driven primarily by two climate-related factors: thermal expansion (ocean water expands as it warms) and the melting of land-based ice from glaciers and ice sheets in Greenland and Antarctica.
