Abstract
In support of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) that should appear in early 2007, modelling groups world-wide have performed a huge coordinated exercise of climate change runs for the 20th and 21st century. In this paper we present the results of the two french climate models, from CNRM and IPSL. In particular we emphasise the progress made since the previous IPCC report and we identify which results are comparable among models and which strongly differ.
