Abstract: Analysis of the sediment form an inland closed lake, Daihai Lack, located in the semiarid and semi-humid zone in north China has revealed the decadal to centennial-scale Holocene climate fluctuations provided by chemical weathering records. High-resolution geochemical, physical and biological proxies form the lake sediments indicate that there is a strong cold climate event in the Early to Middle Holocene transition (EMHT) characterized by weak weathering (sediments with higher Rb/Sr ratios) in single watershed, lake productivity decrease and lower lake level. Although its cold magnitude is weaker than that of Younger Dryas, the coinstantaneous cooling records from lakes (North pole, Africa, North America, West Europe, Tibet, Greenland and north China), oceans (North Atlantic, Mediterranean, Caribbean Sea), mollusk sequences form Europe-American continent, and pole ice cores including Greenland GRIP and GISP2 all indicate a global climate signal which is typically centered between 8.0 and 8.5ka B.P.
