CLIVAR is the World Climate Research Programme project that addresses Climate Variability and Predictability, with a particular focus on the role of ocean-atmosphere interactions in climate. International CLIVAR seeks to identify major emerging climate science questions and to facilitate international coordination, cooperation and capacity building to address these issues. CLIVAR of the future will be more cross-disciplinary and will need to build the application of CLIVAR/ocean science to societal needs.
