ABSOLUTE DATING OF THE CLIMATIC EVENT IN THE 6'TH CENTURY

Various sources, historical, archaeological, geological and geophysical indicate a climatic catastrophe in the 6'th century. In the Greenland ice cores we have a candidate for creating such a catastrophic event. We have a spike in the record of sulfuric acid, followed by a temperature decrease. Investigations of the chemical data indicate a very large unknown volcanic eruption in the order of magnitude of the Tambora AD 1815 eruption. That it was a global event is verified from the Antarctic ice cores. Using the latest data, from the North GRIP ice core correlated to the other ice cores drilled in Greenland and applying a new technique in counting annual layers, we were able to make an absolute dating of the climatic event in the 6'th century.
