Reconstructions of past climate conditions have clearly demonstrated that the spatio-temporal variability of Earth´s climate is paced by orbital forcing and tectonic processes. However, the mechanisms that translate these forcing signals into climate changes and subsequently geoarchives continue to be debated. We invite submissions that explore the climate system response to various forcing mechanisms, and that test the stability of these relationships under different climate regimes or across evolving climate states during the Phanerozoic. A special focus is given to the Pliocene epoch between ~5.3 to 2.7 Ma, which has been proposed as an analogue for future climates, since it is characterised by CO2 concentrations which align with those recorded today and projected for the end of this century under moderate emissions scenarios.
Submissions exploring proxy data and/or modelling work are welcomed, as this session aims to bring together proxy-based, theoretical and/or modelling studies focused on global and regional climate and ecosystem responses to orbital, tectonic and ocean gateway forcing at different time scales. We also encourage contributions linked to the PAGES-PlioVAR and PlioMIP2 programmes.
