Jump to the LGM sensitivity subgroup.
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
The Last Glacial Maximum Sensitivity Subgroup (LGM_sens) was started recently to bring together those who are interested in the experiments which are aimed at analysing the LGM forcings separately. Members may have already have performed runs, be planning to perform runs, or be interested in analysing the runs from different groups.
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. 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.
General Plans: Presently the main aim is to find what runs people have done and and interest in performing. We are also starting to consider ways in which these kinds of experiments may be made more useful or interesting in the future.
