DeepMIP-Phan: a new challenge for Climate models and Paleogeography
Climate model intercomparisons are essential to develop the predictive power of numerical simulations. Deep time models are increasingly needed to explore the Earth System behaviors beyond tipping points. Geologic periods 10s to 100s of millions of years back into the Phanerozoic eon are now in focus but these come with age-increasing paleogeographic uncertainty. Plate tectonic configurations, topographic reconstructions and biogeochemical behaviors become less and less constrained in deeper time. The same applies to proxy datasets required to validate models. Despite these challenges, Phanerozoic simulations open a vast field of fascinating questions on long term evolution and major short-term extreme events.
Target audience:
We will gather climate modelers, paleogeographers and Earth system scientists to present and discuss ways forward to develop the new DeepMIP-Phan project (which numerical models to apply, paleogeographic reconstructions to use, ages to explore, proxies, etc). Please join if you are interested in the topic and willing to contribute your expertise in this exciting endeavour.
Expected outcomes:
The main goal is to gather climate modelers and paleogeographers and Earth system scientists around a new endeavour following the DeepMIP* initiative. "DeepMip-Phan" probing further into deep time throughout the Phanerozoic requires not only to compare types of numerical models but also various paleogeographic reconstruction methods that can deliver widely different constraints. This involves defining new methodological protocols and experimental design for model-paleogeography-data validations and standard formats of end products. We aim to bring together multidisciplinary communities to inform us about key Phanerozoic intervals and significant global to regional paleobiogeographic events and their implications for biogeochemical cycles in the past and the future.
This meeting aims to discuss these issues in order to define the project tasks and participants.
