In order to prepare for future climate change, it is necessary to understand the natural dynamics of the climate and the major terrestrial and marine biomes, as well as the forcing factors that have governed them in the past. This session therefore aims to present work relating to Quaternary climate variability, marked by the rhythm of terrestrial glaciations and rapid infra-orbital changes of varying amplitudes (millennial and multidecadal oscillations), as well as the cryosphere-atmosphere-hydrosphere-biosphere interactions that drive these changes. This session invites multiproxy contributions based on paleoclimatic and paleoceanographic reconstructions presenting long time series from various archives (e.g. lacustrine and marine sediments, speleothems and corals, ice cores). Presentations on the following topics are particularly encouraged:

• Development and application of multi-proxy approaches to distinguish local, regional and global signals,
• Cross-interpretation of chemical, biological and sedimentological signals,
• Integration of proxy data with climate models,
• Chronological synchronisation and inter-archive correlations,
• Study of climate transitions and abrupt events during the Quaternary period

Keywords: paleoclimates, paleoceanography, paleoecology, multiproxy approaches, data models, chronostratigraphy, glacial-interglacial cycles, abrupt events
