ABSTRACT
The signals of fire activity induced from climate and ancient human activities could be recorded in sedimentary strata. We examined a 6000-year blackcarbon (BC) record-including char and soot-of a sediment core from the South Yellow Sea. The climate change had a threshold effect on the fire regime, and dominated the char emissions. The soot/BC signals depicted that the anthropogenic emissions related to the evolution of the Chinese civilization since the Early Bronze Age (~4 ka) have overwhelmed natural soot emissions. The soot variation in the record closely matched periods when there was large-scale use of coal or charcoal after the Han Dynasty and when indigenous coking technology was promoted after the Tang Dynasty; low soot-abundance in the record coincided with periods of social unrest. This work illustrates how soot signals can be a robust tracer of civilization evolution.
