SCOR Working Group 168 Webinar #5

 Title: Secret shifts in the ocean’s biological carbon pump

 Presenter:

Louise Delaigue

Laboratoire d’Océanographie de Villefranche

Recent advances have improved estimates of marine carbon uptake, but the processes driving spatial and vertical variability in biologically mediated carbon fluxes under climate change remain insufficiently understood. Analysis of the past two decades indicates that the global mean of biologically respired carbon has remained stable, yet its vertical and regional distribution is shifting in response to climate-driven changes in circulation, stratification, and ecosystem structure. These reorganizations have not altered the global inventory, but they are reshaping the depth and location of sequestration in ways that reduce the structural stability of the biological carbon pump. This emerging instability in the return flux may pose a greater long-term risk, as it points to a weakening resilience of the ocean carbon sink under continued climate change.

Please save the date for FAIRSEAS, a one-day EuroMarine Foresight Workshop that will bring together three international programs — OASIS, SOLAS, and CLIVAR — to chart the next decade of coordinated air-sea interaction research.

The workshop will feature presentations and discussions spanning observational, modeling, and remote-sensing approaches to better understand the physical, chemical, and biological processes at the air-sea interface. We look forward to connecting the OASIS, SOLAS, and CLIVAR communities to advance this vital global science effort.

As COP30 approaches, members of BEPSII, ASPeCt, CATCH, and PACES have once again come together to issue a unified statement from the scientific community on the state of the cryosphere.

Building on last year’s “S.O.S. from the Poles,” this renewed call highlights the accelerating loss of the world’s ice sheets, glaciers, sea ice, and permafrost, and the cascading risks for global climate, sea level, and human security. It also reminds world leaders that geopolitical tensions and short-term national interests must not distract from the defining global challenge of our time: the climate crisis.

We invite organisations and institutes concerned about the cryosphere and global climate stability to endorse the letter and join this collective call for action. If your organisation endorsed the S.O.S. from the Poles last year, we warmly thank you for your support and invite you to renew your endorsement for this updated statement ahead of COP30.

The letter will circulate for endorsements throughout October 2025 and will be released publicly in early November 2025, ahead of COP30 in Belém, Brazil, and presented again at the COP30 Cryosphere Pavilion.

How to endorse:

1. On behalf of your institute or organisation: Read and endorse the open letter here https://forms.gle/Z6UkhSCijF6tvsSaA if you have the right to do it.
2. As an individual: Forward the message to the decision-maker(s) of your institute/organisation who can undersign the Open Letter; Share the message through your networks, media contacts, and at upcoming events; Amplify the call to action at national, regional, and global scales.

The cryosphere is our planet’s early warning system. Acting decisively now is essential for the future of both the planet and humanity.

On behalf of BEPSII, ASPeCt, CATCH, and PACES,
Letizia, co-chair of BEPSII

Join us 14–16 Oct 2025 for the Virtual Workshop: Ocean Connectivity & Exchange Across the Antarctic Peninsula

Sponsored by the SOOS WAPSA RWG

The Antarctic Peninsula is a critical region of ocean exchange along the Antarctic coast, where the cold Weddell Sea and the warm Bellingshausen Sea meet. In this 3-day virtual workshop on “Ocean Connectivity and Exchange Across the Antarctic Peninsula: Processes and Impacts”, we will discuss the physical drivers modulating the ocean circulation and along-shore exchange in the region and their potential impact on biogeochemical processes.

The workshop will be held on October 14-16, 2025. We will hold three 2.5-hour sessions timed to span as many time zones as possible. Invited talks will be followed by short lighting presentations and discussions.
