This site from the National Climatic Data Center features a tool that displays map images for paleoclimate simulations from various agencies, including COHMAP (CCMO and CCM1), the NASA Goddard Institute for Space Studies (GISS Model II and II') and NCAR. There is also a link to a page containing visualization tools for models from the Paleoclimate Modelling Intercomparison Project(PMIP) database. Each model is extensively documented, and a database is also included.
