"In this presentation, I will explain basic controls on climate and ocean chemistry on different timescales and will examine past climate aberrations and ocean acidification events focusing on the Paleocene-Eocene Thermal Maximum (~56 million years ago). The results allow evaluation of the current anthropogenic perturbation in the context of Earth’s history. It appears that during the Paleocene–Eocene Thermal Maximum processes and/or feedbacks other than direct CO2 forcing alone caused a substantial portion of the warming. These processes are hitherto unknown but need to be identified in order to evaluate their potential effect on future climate change."
