Long-term sea-level change is primarily driven by factors that significantly alter the total volume of water in the oceans or the size of the ocean basins over geological timescales. Melting of large ice sheets (like Greenland and Antarctic ice sheets) adds substantial mass of water to the ocean, directly contributing to long-term sea-level rise. Thermal expansion of seawater due to warming is another significant long-term factor.
