Pan-CLIVAR Meeting and Symposium 2025 was held in Bali

The Pan-CLIVAR Meeting 2025 was held in Bali, Indonesia, from 22nd to 26th of September 2025, attended by over 150 in-person participants from more than 35 countries. This was only the second Pan-CLIVAR Meeting after the 2014 meeting held in The Hague which was instrumental for the development of the current decadal CLIVAR science plan (2018-2028). The 2025 Pan-CLIVAR Meeting, marking CLIVAR’s 30th anniversary, was aimed at initiating the formulation of the next CLIVAR science plan.
Pan-CLIVAR 2025 brought together CLIVAR members from all panels, Research Foci (RF), and scientific steering group (SSG), guests, several representatives from partner projects and institutions, as well as ocean-climate researchers, professionals, and students who participated in the CLIVAR international symposium in the middle of the week. Pan-CLIVAR 2025 comprised of plenary sessions, meetings of the SSG, panels and RF, a session on early career researchers, two side events, and a symposium consisting of 12 sessions and 3 CLIVAR capability breakout sessions.
The event was held online and in person at Bintang Bali Resort located near the international airport for a self-contained and accessible venue. It began with an engaging SSG-only meeting on the afternoon of Monday 22nd of September. The Pan-CLIVAR Meeting was officially opened the next day by the Director of the International CLIVAR Project Office (ICPO) Dr. Agus Santoso, CLIVAR SSG Co-Chair Dr. Gokhan Danabasoglu, co-chair of the World Climate Research Programme (WCRP) joint scientific committee Professor Cristiana Stan, and representatives of Ocean University of China (OUC) and Laoshan Laboratory (China) that co-host the ICPO: the vice president of OUC Prof. Houjie Wang, and the Executive Director of the Leading Group for Foreign Affairs of Laoshan Laboratory Dr. Yanheng Xiao. Their remarks conveyed the motivation and aspiration for Pan-CLIVAR 2025 with acknowledgements of the contributions made by the organisers, volunteers and sponsors in making the event possible.

The opening session concluded with a plenary presentation titled ‘Connecting the WCRP Academy and the CLIVAR Community’ by Dr. Chris Lennard and Prof. Melissa Hart, co-chairs of the WCRP Academy SSG. A group of participants then stayed on for SSG session on partners engagement, and the rest joined parallel meetings of several CLIVAR panels and Research Foci. The SSG session served as a forum for engagement among the various programs and organisations to identify gaps, synergy and cross-cutting issues to sustain and foster collaborations. The panel meetings were attended by several CLIVAR members and invited guests from different countries including Indonesia.

The symposium proceeded with Prof. Mat Collins, symposium committee lead, introducing the CLIVAR Symposium and a research topic in Frontiers in Climate journal which was created specifically for the event with fee waivers available. Two keynote presentations concluded the morning session, delivered by Dr. Supari, head of Climate Variability Analysis Division at BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) of Indonesia on El Niño 2023/24 impact prediction, and Dr. Angelique Melet, head of Ocean Climate Team at Mercator Ocean International in France on coordinated regional ocean climate projections.
The symposium continued with three parallel sessions on the Atmospheric Processes and Climate Dynamics, Ocean-Climate Observations and Modelling, Biogeochemical Processes and Climate Interactions, Artificial Intelligence: Role in Climate-Ocean Research and Prediction, Cascading and Compound Event - Climate Variability and Change, Ocean Processes and Extremes, and a session on Societal Impact. Poster viewing session held in the afternoon further enriched collegial exchanges among the participants. The symposium had 84 oral presentations and 35 poster presentations, led by 36 conveners from various countries. The day concluded with a cultural Balinese dinner reception.

The symposium continued in the morning of Thursday for the second part of sessions Climate Variability and Change, Ocean Processes and Extremes, and Societal Impact, followed by three breakout sessions on CLIVAR capabilities: 1) Climate, atmospheric processes, societal impacts, 2) Ocean processes, modelling, observations, biogeochemistry, and 3) Indo-Pacific Ocean, Climate, and Linkage (a PRP-IORP-TBI RF joint-session). These focus breakout sessions were aimed at assessing CLIVAR capabilities and identifying gaps to drive future initiatives. Participants then gathered in the ballroom for a closing plenary where representatives of the breakout sessions summarised their sessions. The symposium which was attended by several world’s leading scientists and early career researchers identified advances and research gaps that the community need to tackle to move the science forward and to translate the advances to societal applications.
The rest of the afternoon was occupied by parallel sessions: Marine Heatwaves (MHW) Open Session, Tropical Basin Interaction (TBI) Open Session, Early Career Research (ECR) Session, and a Side Event: Enhancing International Ocean-Climate Research Collaboration in a Changing Climate. The MHW and TBI Open Sessions were dedicated to the CLIVAR research focus (RF) groups on the respective topics to provide a forum for interactions between the groups and the wider community. The ECR Session had presentations from CLIVAR and WCRP leadership members who shared their experiences.

To celebrate the successful week which was also dedicated for the 30th Anniversary of CLIVAR, participants gathered for dinner reception by Kuta Beach behind the meeting venue which further promoted social interactions among members and guests.
The Pan-CLIVAR 2025 conclusion on Friday 26 September remained filled with engaging scientific activities starting with a plenary session that was aimed to help initiate the next CLIVAR science plan and implementation strategy. The session began with two plenary talks by Prof. Nicole Lovenduski (Univ. Colorado Boulder) and Dr. Joanna Staneva (Hereon) speaking on Southern Ocean storms’ impact on energy and carbon cycling, and Digital Twins of the Ocean, respectively. The plenary session proceeded with CLIVAR panels and research foci representatives to report on key points that came up at their meetings during the week, and concluded with the announcement of the new CLIVAR logo, new ECR Award scheme, and acknowledgments.
Despite the plenary session formally closing the Pan-CLIVAR 2025, the event was programmed to continue into late afternoon with a side event, a closed SSG meeting, and an SSG Open Session. The interactive side event titled ‘Inclusive Innovation for Ocean and Climate Observations’, was moderated by Prof. Juliet Hermes (CLIVAR SSG member) and co-sponsored by Rip Curl Asia. It was opened by Dr. Nelly Florida Riama, BMKG leadership and Data Buoy Cooperation Panel (DBCP) Chair, followed by a series of presentations on accessible ocean observing technologies before participants headed out to the beach to demonstrate the technological application through surfing.
