  Information - CL019 Modelling the Climates of the Late Quaternary

Event Information
Climates of the Late Quaternary range from full glacial states to interglacial periods similar to or warmer than today. Modelling these climates and the transitions between them still represents a challenge for models of all complexities. At the same time, the late Quaternary offers a unique possibility to test models that are used to predict future climate. Data syntheses already exist for key climatic parameters at periods like the Last Glacial Maximum and the mid-Holocene Optimum, but also time-dependent reconstructions are becoming available for, for example, the last deglaciation. Such reconstructions are used as boundary conditions, but also in model-data intercomparison studies to validate climate models and to identify key forcings and feedbacks within the climatic system for each time period. This session is dedicated to research dealing with the understanding of late Quaternary climate variations on all timescales ranging from Milankovitch to millennial.

We invite papers on model simulations of late Quaternary climate, including both time-slices (as in the Paleo Modelling Intercomparison Project) and transient simulations. This includes complex GCMs, EMICs as well as conceptual models of the Earth System. Comparison of different models, models to data, paleo-data assimilation and the inclusion of proxy-type output to ease model-data comparisons, are particularly encouraged.
