Lakes constitute powerful sedimentary archives of environment over different time-scales. Both the biotic and abiotic sedimentary components may be used to track for environmental changes within the lake column or in its watershed. Information on climate, landscape and ecosystem changes can be provided throughout the Quaternary. Moreover, transfer function and calibration of datasets can provide quantitative information on these past variations. However assessment of climate events in lacustrine sediments requests to decipher between a climate, tectonic or anthropic-derived changes. For this session we invite oral and poster contributions that evidence climatic variations from lacustrine sediments. We invite presentation dealing with new approaches to retrieve quantitative reconstructions from biotic and abiotic sedimentary components. Studies trying to disentangle the natural and human induced changes are particularly welcomed.
