Regional Climate Change Scenario Based on Paleoclimatic Data

Based on paleoclimatic reconstructions of three past warm climates, Mid-Holocene, Eem ian and Mid-Pliocene, the verification of paleoanalog hypothesis is extended to regional level for both precipitation and temperature and to mean latitudinal precipitation as well. It is found that paleoanalog hypothesis holds also for zonal temperatures in cold epoch. Last Glacial Maximum.A typical structure of regional warming and precipitation change is revealed based on the paleoclimatic data. It is shown that over land in temperate northern latitudes the current warming climate generates the similar structure. The observed increase in annual precipitation over NH extratropics agrees with the paleoscenario for precipitation.
