Common Era (last 2000 years) relative sea-level (RSL) records have revealed important insights on the drivers of RSL change; links between climate and sea-level changes; and the timing of the modern acceleration in the rates of sea-level rise. However, the distribution of Common Era RSL records is spatially biased to the North Atlantic. Here, we update the global database of Common Era RSL records with 36 new sea-level index points from coral microatolls and mangrove sediments in Southeast Asia, and 12 RSL data points from a continuous-core mangrove record in Belize. A spatio-temporal hierarchical model is applied to analyse the influence of these new records on the global mean sea-level rate and to attribute regional RSL trends to possible local and regional drivers of RSL change.
