Interannual, decadal and century scale climatic changes revealed by stalagmite records

The stalagmite chronological table is established based on the definition of annual character of microlayers of a stalagmite by comparing the laminated rhythm to natural cyclic processes. Climatic anomalies lasting over ten years and rapid climatic changes such as abrupt changes of mean value, of variability, of trend and of cycles are discovered from the stalagmite chronological table. Stalagmites which record interannual to century scale climatic changes are excellent This work is a part of PANASH/PEP-II Project, and supported by the National Natural Science Foundation of China (Grant Nos.49672134, 49894170), Chinese Academy of Sciences (Grant No.KZ951-A1-402-06-02), and State Science & Technology Commission of China.
