Modelling paleoclimates and the transitions between different climatic states still represents a challenge for models of all complexities. At the same time, the past offers a unique possibility to test models that are used to predict future climate.
We invite papers on paleoclimate model simulations, including time-slices (as in the Paleoclimate Modelling Intercomparison Project) and transient simulations of climate variations on timescales ranging from millennial to glacial cycles and beyond. This session has its focus on (but is not restricted to) the Cenozoic and Cretaceaous.
Comparison of different models (complex GCMs, EMICs and/or conceptual models) and between models and data are particularly encouraged.

Paleoclimate modelling involvement in CMIP5 and CMIP6 has meant that the same state of the art climate models are run for past, present and future climates. This has opened up the opportunity for paleoclimate modelling and data together to inform on future climate changes. We encourage submissions that tackle this, combining models run for the past, present and future with data syntheses to constrain the spread of future predictions. We also encourage submissions which combine models and data in the past to make strong conclusions or testable hypotheses about the future, as well as work highlighting future experiments and data required to strengthen the link to the future.
