As sea level rises in response to climate change so does the demand for a robust global sea level observing system. Buzzanga et al.  show that the laser altimeter carried by the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), part of NASA’s Earth Observing System, is capable of measuring sea level and sea level rise. These ICESat-2 measurements fill two critical gaps in the existing satellite radar systems: the coast and the polar oceans. Robust sea level observations in these regions are critical for understanding and predicting climate change and will be required for effective mitigation and adaptation efforts.
