- We have produced oxygen isotopes record from a speleothem MU-1 from the Mawmluh cave, northeastern India to understand the variability of Indian summer monsoon (ISM) over the last 2000 years. Our record suggest abrupt changes in the ISM during ~113 BC to 1990 AD. Moderate to strong ISM conditions existed during ~113 BC to 440 AD and ~560 to 1040 AD. The precipitation has decreased in the second millennium AD (1000-2000AD) compared to the earlier millennium (0-1000 AD). The end phase of the Medieval Climate Anomaly (MCA; 1040 to 1200 AD) observed drier conditions in northeast India compared to other regional records. The ISM precipitation was generally low in the Little Ice Age (LIA; 1350 to 1850 AD) with some high rainfall phases.
