7.Stalagmite record revealed that Indian summer monsoon moved forward rapidly,and climate undulation on a century scale resulted in the change of the solar radiation.
8.In addition, there are 11 climate wet events as reflected by negative values of stalagmites δ18O that resemble SST variability in Atlantic region (40N). A amplitude of the stalagmite δ18O values averages 1.5%, which is similar to that of the Dansgaard-Oeschger events during the last glaciation.
9.During the early Holocene,stalagmite δ~(18)O record of an average 37-year resolution correlates well with the Greenland temperature record. Firstly,the two records show a similar detailed internal oscillation in YD event and abrupt changes out of YD event.
