Among paleoclimate archives, continental archives (lakes, peatbogs, tree rings, speleothems) are highly sensitive to environmental changes. The evolution of terrestrial ecological systems in response to environmental changes can be assessed from remains of land plants, aquatic plants and animals. Likely the mineralogical and geochemical content of sedimentary records also record changes in the weathering conditions in the terrestrial systems. Both biotic and abiotic sedimentary components may therefore be used to track those environmental changes. A multiproxy approach may usefully shed light on the mechanisms and feedbacks of global and regional climate change. However environmental changes is not only induced by regional or global climate variations but also by, usually more local, tectonic events or human perturbations. In most cases, a spatial comparison of environmental records often allows to decipher between local and regional or global change. For this session, we invite contributions that evidence environmental changes in continental archives during the Quaternary. Our focus will be the identification of the origin of the environmental changes in order to decipher regional or global climate variation during the Quaternary.
