TL;DR: This article reviewed the available evidence for the state of ice sheets during the Pliocene as well as previous attempts to model them and presented new models and sensitivity studies of the mid-Pliocene East Antarctic Ice Sheet (EAIS).

TL;DR: It is found that the potential range of PETM atmospheric pCO2 increase, combined with proxy estimates of the PETM temperature anomaly, does not necessarily imply climate sensitivities beyond the range of state-of-the-art climate models.

TL;DR: General circulation models (GCMs) as discussed by the authors use the laws of physics and an understanding of past geography to simulate climatic responses, and have been used in the prediction of oceanic upwelling sites.

TL;DR: In this article, the climate during the last glacial maximum (LGM) has been simulated using the UK Universities Global Atmospheric Modelling Programme (UGAMP) general circulation model (GCM) with both prescribed sea surface temperatures (SSTs) based on the CLIMAP reconstruction and computed SSTs with a simple thermodynamic slab ocean.

TL;DR: In this paper, a set of high-resolution stable isotope records from multiple archives (lake, bog, marine and ice cores) in the North Atlantic region for the period 9200-7400 yr BP (present = AD 1950).
