Climate parameters of variability and change (natural andanthropogenic) exert considerable influences on all thehuman and natural systems existing on this earth. Theseaspects raise the scientific quest for an understanding ofpalaeoclimate and possible climate dynamics in the future.In the recent past coralline algae has attracted greater focusfrom the palaeoclimate workers across the globe. Thisunderstanding holds critical importance for supporting theneeds of an ever-broadening spectrum of the policy-makersas well as decision-implementing bodies of our society asconsistent efforts are being made to deal with the climateinfluences both at the local as well as global scales. In orderto document the past behavior of the climate systemeffectively, multi-source data is required [1]. Corallinealgae, particularly from the marine realm have the potentialto be one of those sources and have started developing asan excellent proxy for palaeoalgological studies and long-term climate analysis.India is a country rich in both living coralline algae aswell as their fossil counterparts. Fossil coralline algae havebeen recorded from several petroliferous sedimentarybasins of India e.g., Cauvery, Kachchh, Assam Shelf,Andaman-Nicobar and Narmada valley. However, the sci-entific focus has mainly been limited to taxonomic analysis,facies characterization, reconstruction of sedimentaryenvironments, palaeobathymetric zones and ancient shorelines and bars. Till date palaeoclimate studies in India havelargely given impetus to entities like foraminifera, mollusksand bivalves. Unfortunately coralline algae have trailed inthis regard and deserve greater attention as a proxy tool forclimate analysis of the past eras which are a key to thepresent.Coralline algae have a wide coastal distribution in themarine ecosystems right from the neritic to oceanic (epi-pelagic) zones and also possess a wide range of growth-forms, starting from encrusting to lumpy and foliose to thefree-living ones [2], with individual species dependingprimarily on temperature [3]. Coralline algae have a vitalrole in ecosystem management including a diverse rangeof niches [4, 5]. Encrusting coralline algae deposit annualgrowth increments in a high-Mg calcite skeleton and areamongst the longest-living shallow marine organisms.Individual calcified plants can live for several centuries inthe temperate and subarctic oceans. While a large numberof investigations have been successfully applied to obtaingeochemical information pertaining to coralline algalskeletons for reconstructing sea surface temperatures(SST), less attention has been paid till now to employ thegrowth increments as a proxy tool for temperature.According to a recent study, an averaged record of mul-tiple growth increment-width time series of Clathro-morphum compactum specimens across a network of800 km width reveal strong correlations with annualinstrumental SSTs since 1950. Hence, averaging of mul-tiple sclerochronological records of coralline algae canprovide accurate climate information, much like themethods applied in dendrochronology and coral dating.Positive changes in algal growth anomalies record a well-documented regime shift and warming in the northwesternAtlantic during the phase of 1990s. Large positive changesin algal growth anomalies were also present in the 1920sand 1930s and an effective comparison has been madewith that of the 1990s providing the result that the olderimpact may have well exceeded the later one in terms ofmagnitude of warming [6].
