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 and large equator-to-pole temperature gradients, is rooted in environmental changes that promoted Antarctic glaciation ~33.7 million years ago. Onset of Antarctic glaciation reflects a critical tipping point for Earth’s climate and provides a framework for investigating the role of atmospheric carbon… 
Deciphering the role of southern gateways and carbon dioxide on the onset of the Antarctic Circumpolar Current
[1] Growth of Antarctic ice sheet during the Cenozoic 34 million years ago appears as a potential tipping point in the long term cooling trend that began 50 Ma ago. For decades, the onset of the

TLDR
A climate model is used to show that the growth of the ice sheet — forced by changes in CO2 — drove the changes in ocean circulation, in contrast to the opening of the gateways, which had relatively little impact on ocean circulation.
Equatorial heat accumulation as a long-term trigger of permanent Antarctic ice sheets during the Cenozoic
TLDR
It is shown that the Antarctic glaciation at the Eocene−Oligocene boundary was preceded by a period of heat accumulation in the low latitudes, likely focused in a progressively contracting South Atlantic gyre, which contributed to cooling high-latitude austral regions.
Changing atmospheric CO2 concentration was the primary driver of early Cenozoic climate
TLDR
A new high-fidelity record of CO2 concentrations is generated using the boron isotope (δ11B) composition of well preserved planktonic foraminifera from the Tanzania Drilling Project, revising previous estimates and indicating that a large fraction of the warmth of the early Eocene greenhouse was driven by increasedCO2 concentrations, and that climate sensitivity was relatively constant throughout this period.
Antarctic glaciation caused ocean circulation changes at the Eocene–Oligocene transition
TLDR
It is found that growth of the Antarctic ice sheet caused enhanced northward transport of Antarctic intermediate water and invigorated the formation of Antarctic bottom water, fundamentally reorganizing ocean circulation, whereas gateway openings had much less impact on ocean thermal stratification and circulation.
Atmospheric and oceanic impacts of Antarctic glaciation across the Eocene–Oligocene transition
TLDR
It is shown that the global atmosphere and ocean response to growth of the Antarctic ice sheet is sensitive to subtle variations in palaeogeography, using two reconstructions representing Eocene and Oligocene geological stages using the HadCM3L model.
Uncertainties in the Modelled CO2 Threshold for Antarctic Glaciation
Abstract. A frequently cited atmospheric CO2 threshold for the onset of Antarctic glaciation of ~780 ppmv is based on the study of DeConto and Pollard (2003) using an ice sheet model and the GENESIS
Late Oligocene to Pliocene Antarctic climate and oceanographic reconstructions using molecular and isotopic biomarker proxies
Atmospheric CO2 reconstructions ranged between 500 and 300ppm across intervals of significant climate and environmental change from the late Oligocene to the Pliocene, indicating that major climate
Antarctic Climate History and Global Climate Changes
Antarctic climate changes have been reconstructed from ice and sediment cores and numerical models (which also predict future changes). Major ice sheets first appeared 34 million years ago (Ma) and

Rapid Cenozoic glaciation of Antarctica induced by declining atmospheric CO2
TLDR
In this simulation, declining Cenozoic CO2 first leads to the formation of small, highly dynamic ice caps on high Antarctic plateaux, and at a later time, a CO2 threshold is crossed, initiating ice-sheet height/mass-balance feedbacks that cause the ice caps to expand rapidly with large orbital variations, eventually coalescing into a continental-scale East Antarctic Ice Sheet.
Atmospheric carbon dioxide through the Eocene–Oligocene climate transition
TLDR
The results confirm the central role of declining in the development of the Antarctic ice sheet (in broad agreement with carbon cycle modelling) and help to constrain mechanisms and feedbacks associated with the Earth’s biggest climate switch of the past 65 Myr.
Increased seasonality through the Eocene to Oligocene transition in northern high latitudes
TLDR
Northern high-latitude terrestrial climate estimates for the Eocene to Oligocene interval, based on bioclimatic analysis of terrestrially derived spore and pollen assemblages preserved in marine sediments from the Norwegian–Greenland Sea indicate a cooling of ∼5 °C in cold-month (winter) mean temperatures to 0–2‬C, and a concomitant increased seasonality before the Oi-1 glaciation event.
Thresholds for Cenozoic bipolar glaciation
TLDR
It is found that Oi-1 is best explained by Antarctic glaciation alone, combined with deep-sea cooling of up to 4 °C and Antarctic ice that is less isotopically depleted than previously suggested, which implies that episodic northern-hemispheric ice sheets have been possible some 20 million years earlier than currently assumed and could explain some of the variability in Miocene sea-level records.
Global Cooling During the Eocene-Oligocene Climate Transition
About 34 million years ago, Earth's climate shifted from a relatively ice-free world to one with glacial conditions on Antarctica characterized by substantial ice sheets. How Earth's temperature
Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene
TLDR
Stable carbon isotopic values of di-unsaturated alkenones extracted from deep sea cores are used to reconstruct pCO2 from the middle Eocene to the late Oligocene and demonstrate that it ranged between 1000 to 1500 parts per million by volume in the middle to late Eocene, then decreased in several steps during theOligocene, and reached modern levels by the latest Oligaen.
Rapid stepwise onset of Antarctic glaciation and deeper calcite compensation in the Pacific Ocean
TLDR
The changes in oxygen-isotope composition across the Eocene/Oligocene boundary are too large to be explained by Antarctic ice-sheet growth alone and must therefore also indicate contemporaneous global cooling and/or Northern Hemisphere glaciation.

Transient Middle Eocene Atmospheric CO2 and Temperature Variations
TLDR
It appears that vast amounts of CO2 were injected into the atmosphere, and a sea surface temperature increase of as much a 6°C accompanied the atmospheric CO2 rise, suggesting that elevated pCO2 played a major role in global warming during the MECO.
