This study uses big-data bibliometric techniques to analyze nearly 15,000 articles on sea-level rise (SLR) published between 1990 and 2021. Four main research clusters emerged: (I) geological dimensions and sea-level indicators, (II) impacts, risks, and physical components of sea-level change, (III) coastal ecosystems and habitats, and (IV) coastal systems and planning. The analysis reveals a shift in research focus from pure sea-level science towards solution-focused topics like high-end rises, ecosystem service decline, and flood hazards. Developed nations dominate SLR research, highlighting geographical imbalances. The study provides insights into the evolution of research agendas and the challenges for future assessments.
