Dating climatic episodes of the holocene

Top panels are pollen-based reconstructions from Bartlein et al.(2011) with anomalies defined as compared to recent.The dates of environmental and cultural discontinuities are rather similar, particularly during the recent half of the Holocene.The fact that the cultural discontinuities mostly follow rather closely those of the paleobotanical record suggests that there has been a distinct climatic impact on the cultural history of man.

These orbital changes can be easily calculated and predict that the Northern Hemisphere should have been warmer than today during the mid-Holocene in the summer and colder in the winter.Bottom panels are corresponding surface temperature anomalies simulated by the Paleoclimate Modelling Intercomparison Project Phase 2 and 3 (PMIP2 and PMIP3).Graphic from the Intergovernmental Panel on Climate Change Fifth Assessment Report.In summary, the mid-Holocene, roughly 6,000 years ago, was generally warmer than today during summer in the Northern Hemisphere.In some locations, this could be true for winter as well.
