Two volcanoes trigger crises of the late antiquity
Contemporary chronicles, archaeological studies and physical evidence all point to severe climatic changes and ensuing social crises in the middle of the 6th century. New data from ice cores suggest that these events were caused by two major volcanic eruptions. An international team of scientists has reconstructed the effects using state-of-the-art climate models. As they present now the volcanic double event was likely the strongest volcanic driver of Northern Hemisphere climate over the past one and a half millennia.
