TL;DR: This work focuses primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records.

TL;DR: In this paper, the authors show that the current CO2 level can be reduced to at most 350 ppm by phasing out coal use except where CO2 is captured and adopting agricultural and forestry practices that sequester carbon.

TL;DR: 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.

TL;DR: In this article, the authors report proxy records of sea surface temperatures from multiple ocean localities and show that the high-latitude temperature decrease was substantial and heterogeneous, and that Northern Hemisphere glaciation was not required to accommodate the magnitude of continental ice growth during this time.
