Extended Data Fig. 1 | Schematic overview of the computation of
reconstructed sea level and the contributors. Steps with a shaded
background involve steps where each ensemble member is perturbed: for
steps shown in bold, the estimate is drawn from a probability density function;
for steps in italic, the estimate is randomly chosen from a pool of estimates.
All the steps are repeated for each of the 5,000 ensemble members, until the
final step, where all ensemble members are combined to estimate the mean and
confidence interval of the global-mean and basin-mean sea-level budget and its
components. Steps and arrows in orange refer to estimates of steric sea level,
red refers to estimates of ocean mass, dark blue refers to GIA, light blue refers
to tide-gauge observations, yellow refers to VLM, turquoise refers to satellite
altimetry, and purple refers to the budget analysis. The global-mean steric
reconstruction for 1900–2018 is from ref.^15.
