Is Chinese stalagmite delta O-18 solely controlled by the Indian summer monsoon?
As a unique continental archive, speleothem has been widely used in reconstructing paleoclimate change. However, the interpretation of Chinese speleothems delta O-18 has remained a subject of debate. Recently, a Community Atmosphere Model version 3 (CAM3) study indicated that the stalagmite delta O-...

The delta O-18 amplitude of our record is larger than or similar to the stalagmite delta O-18 records from India during these events. In addition, differences of stalagmite delta O-18 in eastern China and the ISM region were observed on glacial-interglacial as well as decadal timescales.

When subtracting the Indian stalagmite delta O-18 series from our XL15 record during H1 period, we found a significant negative correlation with sea surface temperature (SST) record of Western Pacific Warm Pool (WPWP). Consequently, our study suggests that the Chinese stalagmite delta O-18 is controlled by both the ISM and EASM on orbital-, millennial-, and decadal timescales.
