Abstract:
Warm periods of the past offer the chance to test climate models, not just through comparisons with proxy data, but also through model intercomparisons. The idea of an analogue to future global climate change, albeit with caveats, has additionally created much interest in these past periods. Two intercomparison projects have been established to utilise up-to-date paleodata to reconstruct formal boundary conditions for climate simulations. The Pliocene Model Intercomparison Project (PlioMIP), now in its second phase, focuses on the late Pliocene, approximately 3 Ma, while the Deep-Time Model Intercomparison Project (DeepMIP) looks back further to the period between the latest Paleocene and the early Eocene, approximately 55-50 Ma. Here, we present some results using the mid-resolution MIROC4m coupled atmosphere-ocean general circulation model. These results will focus on the most basic experiments specified in the projects, adhering to the protocols and using the boundary conditions provided.
