TL;DR: In this article , Radiometric dates of volcanic/sedimentary rocks and paleotemperatures based on clumped isotopes within ancient soil carbonate nodules from the Lunpola Basin, part of an east-west trending band of basins in central Tibet and now at 4.7 km, suggest that the basin rose from <2.0 km at 50 to 38 million years (Ma) to >4.0 cm by 29 Ma.

TL;DR: In this paper, a single boundary condition (bathymetry) was altered to examine if Pliocene high latitude warming was aided by an increase in poleward heat transport due to changes in the subsidence of North Atlantic Ocean ridges.

TL;DR: In this article, two General Circulation Model simulations of mid-Cretaceous climate are presented, one representing a greenhouse and the other representing an ''icehouse'' world, which may be translated into a number of identifiable signatures in the sedimentary record.

TL;DR: The Mesozoic was one of the warmest intervals in the history of the Earth as mentioned in this paper, during which the single continent Pangea disintegrated into continental units similar to those of today, and there were no significant polar ice caps and sea level was generally much higher than at the present time.

TL;DR: In this paper, the authors present results from an ensemble of eight climate models, each of which has carried out simulations of the early Eocene climate optimum (EECO, g1/4 50 million years ago).
