Monsoons and north China cultural development

Rainfall reconstructions based on lake surface area records from Lake Dali, a closed-basin lake at the modern northwest limit of the East Asian monsoon (EAM), finds that the geographical extent and intensity of the EAM fluctuated in synchrony over the past 125,000 years, and the authors suggest that a substantial decrease in rainfall approximately 5,500 years ago may have driven a large cultural collapse of the Early Neolithic culture in north China. - Read at PNAS.org
