By bridging climate science, policy, and communities through regional platforms such as the Indo-Pacific My Climate Risk Hub at the Indian Institute of Tropical Meteorology (IITM) Pune, India, this paper in Frontiers in Climate outlines pathways for collaborative climate action. This work proposes actionable strategies for regional resilience.This study synthesizes existing climate knowledge for the Indo-Pacific region, emphasizing the need for localized, community-driven adaptation approaches.

Virtual Workshop Series on Stratospheric Aerosol Injection (SAI)

6 – 9 October 2025 via Zoom

The World Climate Research Program (WCRP) Lighthouse Activity “Research on Climate Intervention” and the Core Activity “Atmospheric Processes and their Role in Climate” are hosting a series of Virtual Workshops, in which the community can discuss the topic of Stratospheric Aerosol Injection (SAI), a proposed climate intervention that would aim to reduce the impacts of global warming through the injection of reflective particles in the stratosphere. As this topic becomes more widely discussed, it is important that robust scientific discussions are had to better identify potential risks and impacts of SAI across different scenarios, to understand and reduce uncertainties in future projections using Earth System Models, and to understand potential observational strategies to detect and monitor potential deployments. Furthermore, it is important to foster an inclusive, international dialogue where diverse perspectives are heard.

We welcome brief presentations from groups interested in showcasing and discussing their research on the topic, as well as participants that are interested in learning more and discussing potential future research activities.

Themes:

• Observational strategies: detection, monitoring and attribution
• SAI modeling: processes, capabilities and uncertainties
• Simulation strategies and scenario exploration (emulators)
• Impacts on atmospheric composition, from the stratosphere to air quality
• Global and regional surface climatic impacts, including societal and ecological
• Ethical aspects of studying and testing SAI

The SAI virtual workshops will be held between 6 to 9 Octobre 2025 via Zoom. It will be spread over four sessions to accommodate different time zones, with the following preliminary schedule:

• Session 1: 6 October 2025, 18:00 - 21:00 UTC
• Session 2: 7 October 2025, 15:00 - 18:00 UTC
• Session 3: 8 October 2025, 09:00 - 12:00 UTC
• Session 4: 9 October 2025, 06:00 - 09:00 UTC

Note that the number and length of sessions may be adjusted depending on indicated preferences and abstract submissions.
We plan to record talks and discussions for all sessions, with the recordings open to be viewed by registered participants.

Organizing Committee

The joint CLIVAR-OMDP and RIfS-CORDEX Task Force on Regional Ocean Climate Projections  is assembling a record inventory of regional ocean model projection simulations as both a resource for the regional ocean modeling community, to inform recommendations regarding community needs and priorities. The Task Force is collecting information for this inventory by way of voluntary survey with the intent of making synthesized information publicly available via the Task Force web page.

You’re invited to take the survey using the QR code below or using directly this link https://forms.office.com/e/18yxHGqWPZ  by 1 July 2025.

An international study, published in Science, has found that only 24% of present-day glacier mass will remain if the world were to warm to 2.7°C, the trajectory set by current climate policies. In contrast, limiting warming to 1.5°C — the target of the Paris Agreement — would preserve 54% of glacier mass.

To know more, read the study "Glacier preservation doubled by limiting warming to 1.5°C versus 2.7° - Harry Zekollari et al., Science, 2025, Vol 388, Issue 6750 pp. 979-983, DOI: 10.1126/science.adu4675.

The first Risk-KAN Symposium, convened at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg at April 28th 2025, brought together researchers, practitioners, and stakeholders to chart the future direction of the Knowledge-Action Network on Emergent Risks and Extreme Events (Risk-KAN). Next to serving as the official kick-off of the new working group and leadership structure, the gathering focused on discussing how to advance transdisciplinary risk research and fostering actionable insights to support societal preparedness, resilience, and adaptation to compound and systemic risks in a changing climate.

The 3^rd International Conference on Subseasonal to Seasonal to Decadal Prediction (S2S2D) will take place on 7-11 September 2026 in Reading, UK. This event will provide a forum for the current state of Earth system prediction science to be shared and discussed. It will consist of two parallel sub-conferences, respectively focusing on the subseasonal-to-seasonal and seasonal-to-decadal prediction horizons, together with plenary sessions addressing cross-cutting themes. 

Important Dates

• 1 Dec 2025: abstract submission open
• 1 March 2026: abstract submission closed

To know more about the conference, please visit the S2S2D conference website.

Last week, we had an excellent meeting of authors of the WCRP High-impact climate events, tipping points, and irreversible regional impacts assessment  at the NASA Goddard Institute for Space Studies (GISS) in New York (5-8 May 2025). A lot of progress was made on the Assessment, including nailing down the scope and structure of the publication. We will now be working to produce a first draft of the different sections by the end of June. Huge thanks to AIMES for sponsoring the meeting, to Hannah Liddy and Anastasia Romanou for hosting us at GISS, and to Gabi Hegerl for her leadership.

The WCRP Regional Information for Society (RIfS) Core Project is calling for members of the newly established Robust Information Working Group (RIWG), and associated task teams which will contribute to its work. The aim of the group is to establish what it means for a scientific product to be “robust”, i.e.,  context specific regional climate information that is fit for informing decision-making; and what processes could look like to generate and apply robust information to produce “robust” decisions.

The group aims to identify attributes of robustness of information, identify processes to generate and apply such information, and produce recommendations about what we need to change in our communities of practice, institutions and structures to allow for the achievement of robust climate change information geared towards context-specific decisions.

For more information and to nominate someone (including self-nomination), deadline 15 May 2025 - 17:00 UTC, please visit the open call webpage and the application form.
