Due to the direct relationship between climate and economy (through agriculture), predictive models for climatic changes are very much needed. Climatic prediction is a delicate task and depends upon how well know the past climate. Since the direct observational data for climate (temperature and rainfall) is available for only the last 100-150 years, paleoclimatic reconstruction has to be based on indirect evidences (proxy data) of climatic changes. Attempts are made to use fossilised floral evidence to reconstruct the past climate of the Indian region. However, credibility of paleoclimatic reconstructions based on floral evidences alone can always be increasEd. by comparing them with parallel records generated through other evidences available in the form of tree rings, coral bands, lake sediments, marine sediments, etc. Main objectives are: 1. How marine sediments can be used to reconstruct paleoclirnate? 2. In which way such records can be used to supplement information derived through floral evidences?
