Ancient Climates on Earth


Speaker: Georg Feulner


Within this project, we are exploring interesting paleoclimate problems in earlier epochs of Earth’s history. In particular we are study warm greenhouse-climate states in the past and investigate what we can learn from Earth’s history about our future in a warming world. An ambitious long-term goal of ACE will be a comprehensive synthesis of the co-evolution of climate and the biosphere on very long timescales, combining detailed modelling of time slices at crucial moments in Earth’s history with conceptual models of long-term trends.


Periods currently being investigated

  • 3.8 – 2.5 billion years ago: The climate on early Earth and an exploration of solutions to the faint young Sun paradox
  • 720 – 635 million years ago: Neoproterozoic snowball Earth glaciations
  • 56 – 45 million years ago: early-Eocene warm period
  • 3.3 – 3.0 million years ago: mid-Pliocene warm period
