Welcome to the US Climate Variability and Predictability Program

US CLIVAR Call for Workshops and Working Groups

Requests are now being accepted for US CLIVAR-sponsered workshops and new Working Groups. The call for submissions is open to the US climate science community. Sponsored annually, open community workshops are used to coordinate, develop, plan, and implement new or focused activities for the benefit of the scientific community and relevant to the goals of US CLIVAR. The initiation of two new Working Groups will be sponsored annually with an objective to undertake actionable and measurable tasks over a 2-3 year period.

For more details, review the individual calls:


Working Group

Requests are due by October 17, 2014. 

Joint US CLIVAR and OCB Workshop

Ocean mixing

Ocean's Carbon and Heat Uptake: Uncertainties and Metrics is a joint workshop by the Ocean Carbon Uptake and Southern Ocean Working Groups of US CLIVAR and OCB, which aims to catalyze progress toward understanding the ocean’s role in carbon and heat uptake by strengthening communication and collaboration across traditional disciplinary boundaries to facilitate the exchange of results from recent studies and discuss the most promising directions for future research. The workshop will be December 12-14 in San Francisco, CA. Participation will be limited to 75 scientists, and advance registaration and a brief application are required. 

Variations 2014 Summer Edition

Variations newsletter

The 2014 summer edition of Variations examines the predictability of Arctic climate variability and the impacts of a warming climate. Contributing authors provide insights from sea ice predictions to weather patterns to linkages with lower latitudes, which sheds light on the relationship between a changing Arctic with the rest of the globe.   

US Repeat Hydrography CO2/Tracer Program Accomplishments Report

The US Repeat Hydrography CO2/Tracer Program, having recently completed a decade of full-depth surveys of the world’s ocean basins, has compiled a report summarizing programmatic and scientific achievements. As a contributor to the international Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP), the US program has advanced understanding of the role of the ocean in climate change, carbon cycling, and biogeochemical responses. The report highlights key scientific discoveries and presents future science and monitoring objectives.

Now available online is the sixth annual report for the US AMOC Science Team. This report features progress made in the past year on the main objectives of the program, identifies any programmatic gaps, and makes recommendations on near-term research priorities for the program. Findings and recommendations from an external review process conducted in 2012-2013 and highlights from the US AMOC/UK Rapid international meeting are also featured.

New US CLIVAR Science Plan
