Figure 11. Precipitation-minus-evaporation anomalies for 6000 years B.P. (compared to the present-day) simulated by five atmospheric climate models compared to a map of observed 6ka lake status anomalies reconstructed from paleoclimate data (heavy blue pluses denote much wetter than today, lighter blue pluses wetter, heavy red minuses much drier, light red minuses drier, black circles no change from today). Paleoclimate data such as these are being used to evaluate the performance of climate models in the Paleoclimate Modelling Intercomparison Project (PMIP -Table 3) (courtesy of PMIP and S. Harrison).
