Who We Are
US CLIVAR is a national research program with a mission to foster understanding and prediction of climate variability and change on intraseasonal-to-centennial timescales, through observations and modeling with emphasis on the role of the ocean and its interaction with other elements of the Earth system, and to serve the climate community and society through the coordination and facilitation of research on outstanding climate questions.
Our Research
The ocean plays a key role in providing a major long-term "memory" for the climate system, generating or enhancing variability on a range of climatic timescales. Understanding the ocean's role in climate variability is therefore crucial for quantifying and harnessing the predictability inherent to the Earth system. US CLIVAR-led research has played a substantial role in advancing understanding of, and skill in predicting climate variability and change.

Upcoming Webinars
Usable Climate Risk Science Webinar Series
Vasu Misra (Florida State University)
Naomi Goldenson (WCRP Regional Information for Society International Project Office)
During the seventh webinar in the Usable Climate Risk Science series, we will be joined by Vasu Misra (Florida State University) and Naomi Goldenson (WCRP Regional Information for Society International Project Office).
Vasu will discuss climate science to water management applications in Florida, and Naomi will detail making climate research more context-aware to inform regional challenges.
