A new animation shows how global sea levels have risen more than 80 mm (3.15 inches) over the past three decades. The animation compares global sea levels measured by NASA satellites and those reconstructed using NASA's latest global ocean reanalysis from the Estimating the Circulation and Climate of the Ocean (ECCO) project. Besides showing total sea level rise, the ECCO reanalysis also shows its two main components: seawater expansion from ocean warming (stereodynamic) and increased ocean volume from melting glaciers and ice sheets (barystatic). The datasets are accessible on the PO.DAAC Web Portal: (DOI:10.5067/ECG5D-SSH44), and (DOI:10.5067/ALTCY-TJA50).
