Several researchers have previously identified a severe climatic upheaval in tropical North Africa that began just over 4000 years ago and lasted for about three centuries. The upheaval is known to have occurred shortly after a volcanic eruption, and companion work proposes that this eruption was colossal. Here, we suggest how the eruption acted as a trigger for the upheaval: by forcing changes in ocean circulation; although the initial (atmospheric) forcing lasted only a few years, the ocean… 

A volcanism-based chronology for ancient China

We investigate a proposal of K.D. Pang and co-workers, who identified ancient Chinese texts that appear to record two major volcanic eruptions. The evidence presented by Pang, and substantial
