For continuous records over millions of years, deep-sea carbonate microfossil–based δ<sup>18</sup>O (δ<sub>c</sub>) records are indispensable because they reflect changes in both deep-sea temperature and seawater δ<sup>18</sup>O (δ<sub>w</sub>); the latter are related to ice volume and, thus, to sea level changes. Deep-sea temperature is usually resolved using elemental ratios in the same benthic microfossil shells used for δ<sub>c</sub>, with linear scaling of residual δ<sub>w</sub> to sea level changes. Uncertainties are large and the linear-scaling assumption remains untested. Here, we present a new process-based approach to assess relationships between changes in sea level, mean ice sheet δ<sup>18</sup>O, and both deep-sea δ<sub>w</sub> and temperature and find distinct nonlinearity between sea level and δ<sub>w</sub> changes. Application to δ<sub>c</sub> records over the past 40 million years suggests that Earth’s climate system has complex dynamical behavior, with threshold-like adjustments (critical transitions) that separate quasi-stable deep-sea temperature and ice-volume states.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sea level and deep-sea temperature reconstructions suggest quasi-stable states and critical transitions over the past 40 million years","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-05","DateCreate":"2021-07-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000669960200006","VABBcode":null,"OpenAcc":1,"DOI":"10.1126/sciadv.abf5326"},"refs":null,"anarec":{"AnaID":339584,"PubliDate":2021,"Pagination":"eabf5326","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"26","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":248966,"SerRR":"Science Advances.
