Key outcomes of the CLIVAR Conference and Assessment:
Reconfirmed 4 major Foci
• ENSO• Monsoons• Decadal climate variability-THC• Anthropogenic climate change
• On an annual basis CLIVAR progress will be assessed against four major global themes. Each year a topical workshop will be held for one of the four “total programme” themes.

Key outcomes of the CLIVAR Conference and Assessment:
Future priorities
• CLIVAR visibility and networking• Overall CLIVAR data and information
management
• Applications of CLIVAR science

US CLIVAR Reorganization
• Balanced climate research agenda – understanding, prediction, linkages to users of climate info
• Engage more of scientific community
![Page 21: International CLIVAR Structure, Activities and Future Directions Valery Detemmerman Joint Planning Staff World Climate Research Programme Geneva, Switzerland](https://reader035.vdocuments.mx/reader035/viewer/2022062620/551b8913550346a6148b5ba7/html5/thumbnails/21.jpg)
US and international CLIVAR
• US CLIVAR activities occur within the framework of international CLIVAR
• The US is a key player in international CLIVAR
• One measure is US membership of the CLIVAR SSG, Panels and Working Groups

“….it is recognized that strong linkages to the international CLIVAR ..panels must
continue in order to leverage and coordinate significant international
investments in climate science.”
