TL;DR: In this paper, a set of coupled ocean-atmosphere simulations using state-of-the-art climate models is presented for the Last Glacial Maximum and the Mid-Holocene through the second phase of the Paleoclimate Modeling Intercomparison Project (PMIP2).

TL;DR: A record of global surface temperature from 80 proxy records is constructed and it is shown that temperature is correlated with and generally lags CO2 during the last deglaciation, supporting the conclusion that an antiphased hemispheric temperature response to ocean circulation changes superimposed on globally in-phase warming driven by increasing CO2 concentrations is an explanation for much of the temperature change at the end of the most recent ice age.

TL;DR: The Community Earth System Model Version 2 (CESM2) as discussed by the authors is the most recent version of the Coupled Model Intercomparison Project (CMEI) coupled model.

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: The Palaeoclimate Modelling Intercomparison Project (POMIP) as discussed by the authors evaluated model performance against the geologic record of environmental responses to climate changes and provided a unique opportunity to test model performance outside this limited climate range.
