Comparison of paleoclimate data with GCM`s results and modern climate changes
- State Hydrological Inst., St. Petersburg (Russian Federation)
Three types of data: paleoclimate reconstructions, GCM results, and observations on modern climate change are compared. The paleoanolag hypothesis (PH), which implies that regional patterns of climate change depends mostly on the mean global temperature change, is the basis for this study. Paleoclimate reconstructions for the Mid-Holocene, Eemeian, Mid-Pliocene are used to test the PH. Besides, the results of the GCM models, data on modern climate changes are scaled on the basis of PH. It was shown that the disagreement between paleo- and GCM data is in the difference in describing the equator-pole temperature changes. Precipitation anomalies in GCM data are not in agreement with paleoclimates. Temperature anomalies of the modern warming (1980-s) agree to some extent with paleodata.
