Our results reveals a warm and wet climate from 8000-2000 cal a BP and this was followed by a cooler and drier climate since ~2000 cal a BP. We identified a cooler and drier climate during 7500-7240 cal a BP and this abrupt cooling event have occurred earlier in the southeast relative to the north of China. Solar activity and the influx of meltwater to the North Atlantic were the likely triggers for this abrupt climatic event.
