Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene
The relation between the partial pressure of atmospheric carbon dioxide (pCO2) and Paleogene climate is poorly resolved. We used stable carbon isotopic values of di-unsaturated alkenones extractedExpand

Miocene evolution of atmospheric carbon dioxide
Changes in pCO2 or ocean circulation are generally invoked to explain warm early Miocene climates and a rapid East Antarctic ice sheet (EAIS) expansion in the middle Miocene. This study reconstructsExpand

Thresholds for Cenozoic bipolar glaciation
The long-standing view of Earth’s Cenozoic glacial history calls for the first continental-scale glaciation of Antarctica in the earliest Oligocene epoch (∼33.6 million years ago), followed by theExpand

Subtropical Arctic Ocean temperatures during the Palaeocene/Eocene thermal maximum
The Palaeocene/Eocene thermal maximum, ∼55 million years ago, was a brief period of widespread, extreme climatic warming, that was associated with massive atmospheric greenhouse gas input. AlthoughExpand

The Role of Carbon Dioxide During the Onset of Antarctic Glaciation
Antarctica glaciation began soon after a large decrease in the concentration of atmospheric carbon dioxide around 35 million years ago. Earth’s modern climate, characterized by polar ice sheets andExpand

Antarctic and Southern Ocean influences on Late Pliocene global cooling
The influence of Antarctica and the Southern Ocean on Late Pliocene global climate reconstructions has remained ambiguous due to a lack of well-dated Antarctic-proximal, paleoenvironmental records.Expand

An Ancient Carbon Mystery
Sudden global warming 55 million years ago provides evidence for high climate sensitivity to atmospheric CO, but the source of the carbon remains enigmatic.
