In this Article, owing to a misunderstanding of discussions at the PALSEA2 workshop in Rome, we erroneously reported previous sea-level estimates for the period 3.3–2.9 Myr as originating from the ‘Pliocene Maximum Sea Level’ (PLIOMAX) project. However, these estimates are not from PLIOMAX, relating to ref. 3 instead. We thank M. E. Raymo and A. Rovere for drawing the error to our attention. The online versions of the paper have been corrected.
