PMIP3 WG - Pre-Pliocene climates

Group description

  • To carry out coordinated model simulations of pre-Pliocene time periods, to address key scientific questions related to key intervals, and to evaluate the models by comparisons with palaeo data.
  • To leverage funding for pre-Pliocene climate modelling through coordinated projects.
  • To contribute to the IPCC if appropriate.

Questions to be addressed

What are the key scientific questions?

  • GF: Efficacy of fast feedbacks in a warm world? What feedbacks that operate in warm climates that done operate in more equitable climes? E.g. are their hidden feedbacks and/or sudden jumps in feedback efficacy that lie in wait as we warm the world toward Eocene conditions? Background climate state dependency of feedbacks etc.

What time periods should we target?

What is needed for experimental design – paleogeographies and CO2 primarily – what datasets can we use?

What are the best datasets for model-data comparisons, and how can these be improved?

What are the best methodologies for model-data comparions (close collaboration with the Past2Future working group)
