During the Paleocene-Eocene Thermal Maximum (PETM), ∼56 Mya, thousands of petagrams of carbon were released into the ocean-atmosphere system with attendant changes in the carbon cycle, climate, ocean…

A 4.6‰ decline in the δ13C of atmospheric CO2 is estimated at the onset of the Paleocene-Eocene Thermal Maximum, an abrupt global warming event ∼55.8 Ma, leading to better constraints on past greenhouse-gas perturbations.

Evidence now supports the idea that humans contributed to extinction on some continents, but human hunting was not solely responsible for the pattern of extinction everywhere, and suggests that the intersection of human impacts with pronounced climatic change drove the precise timing and geography of extinction in the Northern Hemisphere.

Floral response to warming and/or increased atmospheric CO2 during the PETM was comparable in rate and magnitude to that seen in postglacial floras and to the predicted effects of anthropogenic carbon release and climate change on future vegetation.
Fossils and fossil climate: the case for equable continental interiors in the Eocene

There are many methods for inferring terrestrial palaeoclimates from palaeontological data, including the size and species diversity of ectothermic vertebrates, the locomotor and dental adaptations…
Eocene continental climates and latitudinal temperature gradients

Global climate during the Mesozoic and early Cenozoic is thought to have been warmer than at present, but there is debate about winter temperatures. Paleontological data indicate mild temperatures…
Sensitivity of leaf size and shape to climate: global patterns and paleoclimatic applications.
It is demonstrated that the inclusion of additional leaf traits that are functionally linked to climate improves paleoclimate reconstructions and illustrates the need for better understanding of the impact of phylogeny and leaf habit on leaf-climate relationships.
Paleobotanical evidence for near present-day levels of atmospheric Co2 during part of the tertiary.
This reconstruction indicates that CO(2) remained between 300 and 450 parts per million by volume for these intervals with the exception of a single high estimate near the Paleocene/Eocene boundary, and suggests that factors in addition to CO( 2) are required to explain these past intervals of global warmth.
Oxygen isotope and paleobotanical estimates of temperature and δ18O–latitude gradients over North America during the early Eocene
Empirical estimates of climate parameters such as mean annual tempera- ture (MAT) are essential to describe both ancient climate and to ground truth climate model simulations of past climates. In…
