Palaeoclimate science for a better understanding of Earth system dynamics

Expected Outcome: Project results are expected to contribute to some of the following outcomes: Better process understanding of past climate changes at different time scales, their variability and interactions with ecosystems, leading to improved Earth system models; Future climate change scenarios produced in light of past changes in the Earth system, in particular warm climates/high sea-level situations, and abrupt transitions; Identification of thresholds in Earth system components and better characterisation of driving mechanisms and feedbacks that may be responsible for non-linear behaviours, including indicators of abrupt changes, and early warning signals within palaeoclimate records; Synthesis of climate variations that can serve as fundamental basis for IPCC assessments and benchmarks for model inter-comparisons. Scope: Palaeoclimatic (including geological, biological and ice-core) records provide information on the long-term evolution of the climate, as well as the conditions and processes that can drive physical and ecological systems during warm and cold periods, deglaciations and abrupt climatic events. The challenge of the research under this topic is to provide robust information on palaeoclimate states and events outside the range of variability recorded over the past centuries that can serve as guide for the development of Earth system models. This challenge will be tackled through some of the following activities: Producing and aggregating in databases high-…bron
