TL;DR: The first synchronously coupled atmosphere-ocean general circulation model simulation from the Last Glacial Maximum to the Bølling-Allerød (BA) warming reproduces several major features of the deglacial climate evolution, suggesting a good agreement in climate sensitivity between the model and observations.

TL;DR: In this paper, the climate sensitivity of the Community Climate System Model version 3 (CCSM3) is studied for two past climate forcings, the Last Glacial Maximum (LGM) and the mid-Holocene.

TL;DR: In this paper, the authors investigate the atmospheric response to projected Arctic sea ice loss at the end of the twenty-first century using an atmospheric general circulation model (GCM) coupled to a land surface model.

TL;DR: A coupled climate system model was used to determine whether proxy-based irradiance series are capable of inducing climatic variations that resemble variations found in climate reconstructions, and if part of the previously estimated large range of past solar irradiance changes could be excluded.

TL;DR: In this article, the atmospheric changes that may have occurred in response to Arctic sea ice loss were analyzed using the atmospheric general circulation model (AGCM) experiments in which the only time-varying forcings prescribed were observed variations in Arctic Sea ice and accompanying changes in Arctic sea surface temperatures from 1979 to 2009.
