Recent advances in paleoclimate modeling: toward better simulations of warm paleoclimates
Numerical climate models have been applied to problems of paleoclimatology for several decades. During that time, climate models have progressed in complexity from relatively simplistic Energy Balance Models (EBMs) to sophisticated three-dimensional General Circulation Models (GCMs) of the atmosphere and oceans. Recent advances in climate modeling, mainly the incorporation of climate system processes once generalized or ignored and the interactive ‘coupling’ of climate system components, are leading toward more realistic paleoclimate simulations and a new understanding of warm paleoclimate dynamics. The future promises even more comprehensive models running at higher resolutions, allowing paleoclimate modeling studies to focus on subcontinental to regional-scale problems. However, as the models gain sophistication, paleoclimate modeling strategies become more complex. The set-up and initialization of GCMs using Atmospheric General Circulation Models (AGCMs) coupled to full-depth, dynamical Ocean General Circulation Models (OGCMs) will provide one of the primary challenges for the paleoclimate modeling community in coming years.
