Climate change: French researchers complete new simulations for the next IPCC report
The French climatology community, which includes CNRS, Météo-France, the CEA, UPMC and UVSQ, has just completed a major exercise in the simulation of past and future climate conditions on a global scale. This new body of data confirms the conclusions of the most recent report by the IPCC(2007) on future changes in temperature and rainfall. By 2100, average global temperatures are expected to rise by 3.5 to 5°C according to the most unfavorable scenario, or 2°C according to the most optimistic projections. This study has been made available to the international community, and will be used by the IPCC in its next report, to be released in 2013. It provides information on likely climate conditions and trends at the end of the century and, for the first time, over the next 30 years as well.
