AbstractSea-level histories during the two most recent deglacial–interglacial intervals show substantial differences1,2,3 despite both periods undergoing similar changes in global mean temperature4,5 and forcing from greenhouse gases6. Although the last interglaciation (LIG) experienced stronger boreal summer insolation forcing than the present interglaciation7, understanding why LIG global mean sea level may…
