The Tuning Strategy of IPSL‐CM6A‐LR
Résumé
Climate change is a serious issue for humanity with important ramifications for policy and decision making. Robust and cost-efficient policies on mitigation and adaptation require assessments of current and future risks for natural and human systems under a range of socioeconomic scenarios. Those assessments rely on numerical simulations performed with state-of-the-art climate models. Simulations are coordinated at an international level within the Coupled Model Intercomparison Project (CMIP) which provides the bedrock for a substantial part of the publications synthesized in the Intergovernmental Panel on Climate Change (IPCC) reports. Such projects are fundamental in order to document the robust features as well as the relatively large uncertainties in the future climate projections. Among others, these uncertainties come from the various assumptions made by the ∼30 teams that develop CMIP-class models. In particular, because of
