The 2018 winter edition of Exchanges and Variations, joint between International and US CLIVAR, is themed "Sea Level Rise," with guest editor John Church, University of New South Wales. The issue discusses the latest research, evaluation of predictability, analysis of extreme events and surface waves, and examples of the impacts.

US CLIVAR welcomes new members to the leadership team and panels, who will help shape the science planning and implementation of program goals. 

In recognition of 20 years of advancing climate research, US CLIVAR is seeking testimonials from the community and agency sponsors who have helped shape the program. Read what the community has to say and please consider sharing your testimonial. 

Poster abstracts and early career travel support requests are due March 5 for the workshop on Bridging Sustained Observations & Data Assimilation for TPOS 2020 to be held in Boulder, Colorado, May 1-3, 2018. This workshop will bring together the observational, modeling, and data assimilation communities to rethink the next-generation sustained observing system in the tropical Pacific. Registration will close April 18. 

For the past 20 years, the US CLIVAR program has addressed some of the most pressing research questions to understand the climate system, particularly the great uncertainties related to the role of the ocean. To recognize the community and build on achievements, the program will host several events throughout the year. 

At the 2018 Ocean Sciences Meeting, International and US CLIVAR will host a town hall on Thursday, February 15 at 12:45 pm on “CLIVAR’s Course: Accomplishments and Future Science Priorities.” Additional sessions relevant for the community have also been compiled. 

Advancements in research into how the climate interacts with the Earth system are showcased in this collection of published highlights from 2017, featuring science conducted by members of the US CLIVAR community. 

Dan Vimont, University of Wisconsin-Madison, will serve as the new chair of the US CLIVAR Scientific Steering Committee (SSC) through 2018. The SSC chair directs US CLIVAR activities by advancing the Science Plan, identifying new opportunities for engagement, and serving as an ambassador for the program. 

The US CLIVAR Scientific Steering Committee seeks qualified individuals to serve on its three subsidiary panels beginning in 2018. Panel members formulate science goals and implementation strategies, catalyze and coordinate activities, and work with agencies and international partners to advance the progress of the climate research community. Nominations or self-nominations are due January 3, 2018. 

Western boundary current regions are often studied for their intensity of air-sea interaction and mesoscale variability, yet research addressing the implications of these characteristics for biogeochemical cycling has lagged behind. This latest edition of Variations, joint with US OCB, features articles discussing some of the most pressing research questions.
