Multiproxy records of vegetation and monsoon variability from the lacustrine sediments of eastern Ganga Plain since 1350Â A.D.

Pollen analysis coupled with sediment grain parameters indicate intense ISM from 1400 to 1600 A.D. and 1850 A.D. onwards and weak monsoon around 1600-1750 A.D. The signals of weak monsoon around 1650, 1770 and 1850 A.D. are synchronous with the Little Ice Age.
