Nice paper led by @leonchafik.bsky.social on the North Atlantic-Nordic Seas overturning circulation.
Warm & salty North Atlantic water transport to the Nordic Sea (NS) across the Greenland-Scotland Ridge (GSR) didn't show a slowdown since 1972. Instead, it exhibited multidecadal variability. The NS overflow & AMOC across the GSR also display a similar signal. 🌊🧪👍 doi.org/10.1038/s43247-025-02557-x

The worldview of sea surface temperatures really does put into perspective how extreme the anomalous warmth is off the coast of Ireland.
It's the biggest & most intense marine heatwave on the planet, some >5°C above normal. Enhanced rainfall & hotter heatwaves a possible impact.
