Graph from ice cores showing abrupt climate change 8200 years ago
This figure which is courtesy of IGBP/PAGES shows snow accumulation and isotopically inferred temperature records in the Greenland GISP2 ice core and a temperature record derived from oxygen isotope measurements of fossil shells in the sediments of Lake Ammersee, southern Germany. These records all show a major climatic instability event which occurred around 8200 years ago, during the Holocene. The event was large both in magnitude, as reflected by a temperature signal in Greenland of order 5 °C, and in its geographical extent, as indicated by the close correlation of the signal in these two locations. The dramatic event is also seen in the methane record from Greenland indicating possible major shifts in hydrology and land cover in lower latitudes. source: VonGrafenstein et al (1998) Climate Dynamics, 14, 73-81.
