TL;DR: In this article, an ensemble of simulations with the Community Earth System Model (CESM) for the period 850-2005 (the CESM Last Millennium Ensemble, or CESM-LME) is now available to the community.

TL;DR: The CCSM4 LM simulation as discussed by the authors reproduces many large-scale climate patterns suggested by historical and proxy-data records, with Northern Hemisphere (NH) and Southern Hemisphere (SH) surface temperatures cooling to the early 1800s Common Era by ~0.5°C and ~ 0.3°C, respectively, followed by warming to the present.

TL;DR: In this article, the authors use five Coupled Model Intercomparison Project 5 class Earth system model large ensembles to show how the Arctic is transitioning from a dominantly frozen state and to quantify the nature and timing of an emerging new Arctic climate in sea ice, air temperatures and precipitation phase (rain versus snow).

TL;DR: In this paper, the authors assess the sea ice response to Southern Annular Mode (SAM) anomalies for pre-industrial control simulations from the Coupled Model Intercomparison Project (CMIP5).

TL;DR: The Community Climate System Model, version 4 (CCSM4) as discussed by the authors provides a powerful tool to understand and predict the earth's climate system, including surface climatology and interannual variability, simulation of key climate water masses (Antarctic Bottom Water, Subantarctic Mode Water, and Antarctic Intermediate Water), transport and structure of the Antarctic Circumpolar Current, and interbasin exchange via the Agulhas and Tasman leakages and at the Brazil-Malvinas Confluence.
