The general purpose of this issue of Climate Dynamics is:
- To present the IPSL and CNRM Earth System Models.
- To discuss few results obtained in the framework of the CMIP5 relative to the CMIP3, in terms of simulations and forcings.


Model description and basic evaluation :

Climate variability and dynamical studies :

Analysis of the climate response to external forcings (anthropogenic, paleo, volcanic..)

Regional studies :

Earth-System interactions (chemistry, bio-geochemistry):
