Paleoclimate modellers have for many years argued the importance of paleoclimate simulations as a means of increasing understanding of the climate system. However, it is only in the latest iteration of the climate model inter-comparison project (CMIP5) that paleoclimate runs have been officially included. This means that, for the first time, there exists a coherent ensemble of climate models run for past climates, recent historical, control and future scenarios.
This working group seeks to help climate scientists make the best use of this unique situation, so that they may better use past climate information from models and data to learn about future climates.
The working group was initiated at the PMIP3 2012 Crewe meeting
Aims and Scope v2.1, July 2014. Compared to v2.0, the strategy has been slightly revised to include consideration of processes and explicitly include comparison with data. See below in Previous Aims and Scopes section for v2.0, June 2014, which resulted from the PMIP3 meeting, 25-30 May 2014, Namur, Belgium.
To use paleoclimate information to improve predictions of climate change
* Code for methodologies should be fully published to enable participation of others
* More targets? This is open to development later.
* Considerable interaction with the rest of PMIP will be required.
* Dan Lunt has funds to host a workshop in the UK on Past to Future, sometime in the next couple of years.
Aims and Scope (v1.0) of the P2F working group.
Aims and Scope (v2.0) of the P2F working group, June 2014.
The basic Last Glacial Maximum (LGM) protocol in PMIP/CMIP aims to realistically simulate the LGM. This involves changes compared to the present day in the imposed greenhouse gases, ice sheets, and orbital solar forcing. Considerable mismatch between models and data remains, and this subgroup aims to consider the forcings separately in order to diagnose the effect of the different feedbacks, and to consider nonlinearities in the response to forcing that are relevant to expected future changes in the climate.
