RECONSTRUCTIONSof early Eocene climate depict a world in which the polar environments support mammals and reptiles, deciduous forests, warm oceans and rare frost conditions 1–5. At the same time, tropical sea surface temperatures are interpreted to have been the same as or slightly cooler than present values6. The question of how to warm polar regions of Earth without noticeably warming the tropics remains unresolved; increased amounts of greenhouse gases would be expected to warm all latitudes…

TLDR
This study explores the sensitivity of the simulated pre-PETM and PETM periods to change in cloud condensation nuclei (CCN) and microphysical properties of liquid water clouds and indicates that past differences in cloud properties may be an important factor in accurately simulating past warm climates.
Increased terrestrial methane cycling at the Palaeocene-Eocene thermal maximum.
TLDR
The data suggest that the release of methane from the terrestrial biosphere increased and possibly acted as a positive feedback mechanism to global warming.
Climate sensitivity to Arctic seaway restriction during the early Paleogene
Past extreme warming events linked to massive carbon release from thawing permafrost
Between about 55.5 and 52 million years ago, Earth experienced a series of sudden and extreme global warming events (hyperthermals) superimposed on a long-term warming trend. The first and largest of
The ocean circulation in the southern hemisphere and its climatic impacts in the Eocene
Enhanced chemistry-climate feedbacks in past greenhouse worlds
TLDR
Results from a series of three-dimensional Earth system modeling simulations indicate that the greenhouse worlds of the early Eocene and late Cretaceous maintained high concentrations of methane, tropospheric ozone, and nitrous oxide, and point to chemistry-climate feedbacks as possible amplifiers of climate sensitivity in the Anthropocene.
Geobiological constraints on Earth system sensitivity to CO₂ during the Cretaceous and Cenozoic.
Earth system climate sensitivity (ESS) is the long‐term (>103 year) response of global surface temperature to doubled CO2 that integrates fast and slow climate feedbacks. ESS has energy policy
Impact of a Tethyan circumglobal passage on ocean heat transport and “equable” climates
[1] The presence of low-latitude circumglobal passage from the late Jurassic (∼160 Ma) through the Miocene (∼14 Ma) provides a possible mechanism for increased poleward ocean heat transport during
Geologic constraints on earth system sensitivity to CO 2 during the Cretaceous and early Paleogene
Abstract. Earth system sensitivity (ESS) is the long-term (>103 yr) equilibrium temperature response to doubled CO2. ESS has climate policy implications because global temperatures are not expected
