Numerous observations indicate that speleothems can record signatures of the past climate variability. Systematics of stable isotopes and trace elements in speleothems and current methods of dating are discussed. δ 18O in Indian speleothems is presently being used as a monsoon proxy. Several records from Indian karst locations are available, many of these cover recent several millennia and some extend back to ~280 ka. Salient features of monsoon variability reconstructed so far from Indian speleothems is briefly discussed. Some of the δ 18O records show presence of non-persistent periodic changes suggesting controls of subtle variations in solar output and internal changes in the climate system.
