TL;DR: This paper reviewed events exhibiting evidence for elevated atmospheric CO2, global warming, and ocean acidification over the past ~300 million years of Earth's history, some with contemporaneous extinction or evolutionary turnover among marine calcifiers.
Journal ArticleDOI
A study of cleaning procedures used for foraminiferal Mg/Ca paleothermometry
TL;DR: In this paper, various cleaning steps required for preparation of foraminiferal samples for Mg/Ca (and Sr/Ca) analysis are evaluated for their relative importance and effects on measured elemental ratios.
Journal ArticleDOI
Interhemispheric Atlantic seesaw response during the last deglaciation.
Stephen Barker,Paula Diz,Maryline J Vautravers,Jennifer Pike,Gregor Knorr,Ian Hall,Wallace S. Broecker +6 more
TL;DR: New records from the South Atlantic are presented that show rapid changes during the last deglaciation that were instantaneous (within dating uncertainty) and of opposite sign to those observed in the North Atlantic.
Journal ArticleDOI

TL;DR: This article presented an updated synthesis of sea surface temperatures during the Last Glacial Maximum, rigorously defined as the period between 23 and 19 thousand years before present, from the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) project.
Journal ArticleDOI
Ventilation of the Deep Southern Ocean and Deglacial CO2 Rise
TL;DR: Radiocarbon data from the Southern Ocean indicate that the deep water circulating around Antarctica was about twice as old relative to the atmosphere as it is today, a condition considered indicative of carbon dioxide accumulation and storage.
