This week, the 2025 Arctic-Subarctic Ocean Fluxes (ASOF) workshop was hosted by ICM in Barcelona and thanks to @iasc-arctic.bsky.social cross-cutting workshop funding we could support the travel of 7 Early Career and Indigenous participants.

[1/4] 📢 New Preprint Alert! 📢 Is the AMOC's fate already sealed until 2050? We've just dropped a preprint where we partition sources of #AMOC variability from 1850 to 2100 in #CMIP6 ensembles using ANOVA. In this thread, a quick summary of the key points and method! 👇 #Climate
Past, Present, and Future Variability of Atlantic Meridional Overturning Circulation in CMIP6 Ensembles
Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the climate system, exhibiting strong variability across daily to millennial timescales and significantly influen...

New paper published today by @elodieduyck.bsky.social, myself, and @eleanorfrajka.bsky.social on the freshwater pathways along the Newfoundland and Labrador Shelf. Freshwater anomalies from Hudson/Baffin Bays likely bypass Labrador Sea convection region: os.copernicus.org/articles/21/...
Circulation of Baffin Bay and Hudson Bay waters on the Labrador shelf and into the subpolar North Atlantic
Abstract. In the coming decades increasing amounts of freshwater are predicted to enter the subpolar North Atlantic from Greenland and the Arctic. If this additional freshwater reaches the regions whe...

Does an increase in AMOC variability signal an imminent tipping point? In a recent article in GRL (@agu.org), authors explore the possibility of false positives (increased variance but no bistability) depending on gyre circulation intensity.

Slowed Response of Atlantic Meridional Overturning Circulation Not a Robust Signal of Collapse
Critical Slowing Down (CSD) indicators can raise a false alarm of a nonexistent collapse when applied to an idealized Atlantic meridional overturning circulation (AMOC) model Applying CSD to the ...
