- W2390697666 abstract "Global change is a modern frontier project of earth science In order to predict future climate change and well understand the dynamic process of earth evolution, the high resolution climate change history of the last two glaciations must be studied and reconstructed On the basis of sedimentation investigation of several large stalagmites, the high resolution record of climate change since 160000a B P in Guangxi and Guizhou provinces have been studied using carbon and oxygen stable isotope, αU series, and TIMS U series The records of the climate change from stalagmites since 160000a B P can be correlated with the 1 to 6 stages of that from the ocean The time of the beginning and ending points of the last glaciation were estimated as(130 1 ±1 0) ka B P and (11 2±0 1) ka B P The accuracy from the stalagmite record is much higher than that from other record The results indicates the epochs of Heinrich climate oscillation from stalagmite are H1 14~15kaB P , H2 21~23kaB P , H3 25~27 ka B P and H4 41~42kaB P Furthermore, there was a large cold event at 35~37kaB P Therefore, the record of last glaciation from stalagmite may well correlate with the record from Greenland ice core Regarding the existance epochs lagging or surpassing for long term climate cycle to short term abrupt climate event, perhaps, these were errors from different test methods and test objects (including test error) If there would be more evidences, the epochs of some climate abrupt events in the global change could be confirmed to be in the same time The dynamic mechanism of the short term abrupt event might attribute to the astronomical factors as long term climate cycle However, the astronomical factors, which influenced the short term abrupt climate event, cannot be recognized at present" @default.
