The primary aim of this special issue as part of the PALeo constraints on SEA level rise 2 (PALSEA2) Past Global Changes (PAGES) working group and international focus group of the Coastal and Marine Processes commission in International Union for Quaternary Research (INQUA) is to use the information contained in the geological record to improve the accuracy of sea-level projections for the coming centuries to millennia. The focus is on documenting and synthesizing data on rates, sources, and budgets of sea-level variability during Quaternary/Pliocene warm periods, including the transition into and out of such periods, and assess the ability of models to simulate these observations.
