Despite much progress made over the last decades, the nature and reasons of climate variability on Earth are still insufficiently understood. This is particularly true for the Arctic, which is currently experiencing a much more pronounced warming than the rest of the globe. Lacustrine sediments represent ideal archives to reconstruct the environmental conditions that prevailed during lake evolution, and can provide significant information for the local and regional responses to global climate change on the continents on short (up to annual) and long (millennial to orbital) time scales. In this session, we invite presentations that aim at investigating the regional responses of the Quaternary climate and environment on external forcing and feedback mechanisms in Northern Eurasia, through analysis of sediment sequences within lakes. We thus invite submissions that aim to present Quaternary environmental and climatic reconstructions based upon analysis of sediment records, geophysical data and climate models to outcome a better understanding of the temporal and spatial variability and development of the Arctic during the Quaternary.
