Short summary
In this study, we use climate modeling to investigate the relative impact of CO2 and orbit on Early Eocene (~ 55 million years ago) climate and compare our modeled results to fossil records to determine the context for the Paleocene–Eocene Thermal Maximum, the most extreme hyperthermal in the Cenozoic. Our conclusions consider limitations and illustrate the importance of climate models when interpreting paleoclimate records in times of extreme warmth.

Short summary
The mid-Pliocene (MP; ∼3.0 Ma) had CO2 levels similar to today and average temperatures ∼3°C warmer. At terrestrial high latitudes, MP temperatures from climate models are much lower than those reconstructed from data. This mismatch occurs in the winter but not the summer. The winter model–data mismatch likely has multiple causes. One novel cause is that the MP climate may be outside the modern sample, and errors could occur when using information from the modern era to reconstruct climate.

Short summary
Temperature seasonality is an important climate parameter for biodiversity. Fossil plants describe its middle Eocene to early Oligocene increase in the Northern Hemisphere, but underlying mechanisms have not been studied in detail yet. Using climate simulations, we map global seasonality changes and show that major contemporary forcing – atmospheric CO2 lowering, Antarctic ice-sheet expansion and particularly related sea level drop – participated in this phenomenon and its spatial distribution.

We use an isotope-equipped GCM and develop original theoretical expression for the precipitation composition to assess δ18O of paleo-precipitation changes with the Tibetan Plateau uplift. We show that δ18O of precipitation is very sensitive to climate changes related to the growth of mountains, notably changes in relative humidity and precipitation amount. Topography is shown to be not an exclusive controlling factor δ18O in precipitation that have crucial consequences for paleoelevation studies

Short summary
We critically assess, for the first time since its inception in 1997, the theory behind the Coexistence Approach. This method has reconstructed purportedly accurate, often highly precise, palaeoclimates for a wide range of Cenozoic Eurasian localities. We argue that its basic assumptions clash with modern biological and statistical theory and that its modus operandi is fundamentally flawed. We provide guidelines on how to establish robust taxon-based palaeoclimate reconstruction methods.

Short summary
In this paper, we assess how well model-simulated precipitation rates compare to those indicated by geological data for the early Eocene, a warm interval 56–49 million years ago. Our results show that a number of models struggle to produce sufficient precipitation at high latitudes, which likely relates to cool simulated temperatures in these regions. However, calculating precipitation rates from plant fossils is highly uncertain, and further data are now required.

Short summary
An abrupt increase in seasonal precipitation during the PETM in the Pyrenean Gulf has been proposed, based on the occurrence of extensive fine-grained siliciclastic deposits. This paper provides evidence that coarse-grained siliciclastics were also delivered, indicative of episodes of intense rainy intervals in an otherwise semiarid PETM climate. Further, evidence is presented that PETM kaolinites were most likely resedimented from Cretaceous lateritic profiles developed in the basement.
