Percentages show contribution from each source for each 5-year period, calculated based on the total positive contribution to sea level rise during that period. Land ice contributions are taken from Bamber et al. (2018). Steric contributions use the Total Steric Level Anomaly (TSSLA) 0-2000m given by NOAA’s World Ocean Atlas 2009 (WOA09).
