title = "Cenozoic sea-level and cryospheric evolution from deep-sea geochemical and continental margin records",
abstract = "Using Pacific benthic foraminiferal δ18O and Mg/Ca records, we derive a Cenozoic (66 Ma) global mean sea level (GMSL) estimate that records evolution from an ice-free Early Eocene to Quaternary bipolar ice sheets. These GMSL estimates are statistically similar to “backstripped” estimates from continental margins accounting for compaction, loading, and thermal subsidence. Peak warmth, elevated GMSL, high CO2, and ice-free “Hothouse” conditions (56 to 48 Ma) were followed by “Cool Greenhouse” (48 to 34 Ma) ice sheets (10 to 30 m changes). Continental-scale ice sheets (“Icehouse”) began ~34 Ma (>50 m changes), permanent East Antarctic ice sheets at 12.8 Ma, and bipolar glaciation at 2.5 Ma. The largest GMSL fall (27 to 20 ka; ~130 m) was followed by a >40 mm/yr rise (19 to 10 ka), a slowing (10 to 2 ka), and a stillstand until ~1900 CE, when rates began to rise. High long-term CO2 caused warm climates and high sea levels, with sea-level variability dominated by periodic Milankovitch cycles.",

note = "Funding Information: We thank the IODP paleoceanographic community for their efforts on generating the exquisite records (most notably A. Holbourn and T. Westerhold), R. Fairbanks for his original (1984) suggestion to “scale δ18O records to sea level,” numerous colleagues who participated in generation of the “NJ sea-level curve” (especially M. Kominz, P. Sugarman, and S. Pekar), B. Cramer for his Mg/Ca synthesis, and the founders of pre-Quaternary paleoceanography and cryospheric communities (especially J. Kennett, N. Shackleton, S. Savin, C. Denton, and R. K. Matthews) who saw much of the broad picture, although we may now differ on critical details. We thank M. Simmons (Halliburton) for comments and three anonymous reviewers. We thank the Office of Advanced Research Computing (OARC) at Rutgers University for providing access to the Amarel cluster and associated research computing resources.
