By linking Antarctic sea ice, cloud cover, deep ocean temperatures, and global warming, our new study led by @linusvogt.bsky.social finds that ocean heat uptake and thermal sea level rise by 2100 could be 3–14% higher, and global surface warming 3–7% greater than previously thought👇

Linus Vogt@linusvogt.bsky.social · 10mo ago

🚨🌊 New highlight paper out today in Earth System Dynamics! We find an observational constraint implying more future global ocean heat uptake, cloud feedback, and warming than the CMIP6 mean. This contrasts with previous estimates based on past warming trends. 🔗 esd.copernicus.org/articles/16/...

You can still apply! If you know someone who might be interested, tell her or him about this! 🌊

As straddling stocks shift between EEZs and the high seas due to climate change, fisheries will require adaptive management.

Fish stocks are on the move due to #climatechange, impacting the sustainability of important #fisheries. 37% of straddling stocks are projected to have significant shifts between EEZs and the high seas by 2030, more than 50% by 2050. oceans.ubc.ca/2025/07/31/s... @julianop.bsky.social

This is phenomenal. Sea surface temperatures are >5C above average to the west of the UK and around Iceland. It's the strongest area of anomalous warmth on the planet at the moment. It's the warmest in recorded history for northwest Europe.

New study led by @lilianschuster.bsky.social finds that temporarily overshooting +1.5°C leads to irreversible glacier loss and long-term changes in water runoff. Some fast-responding glaciers may regrow, but this could lead to water scarcity centuries later, a phenomenon called ‘trough water’.👇

Lilian Schuster@lilianschuster.bsky.social · last yr.

🏔️🌍🌎🌏 New study warns: Even if we only temporarily exceed 1.5 °C, mountain glaciers face irreversible losses lasting centuries. Such an overshoot reduces glacier runoff, specifically in regions where some glaciers regrow. Further interested? Check out our new publication: doi.org/10.1038/s415...

Sixty-six percent of the entire planet is deep ocean (≥200 m), and a new study shows that less than 0.001%, a total area approximately a tenth of the size of 🇨🇭 has been visualized observed. There is soooo much to be discovered! www.science.org/doi/10.1126/...

In decades of deep-sea exploration, humans have observed only 0.001% of the deep seafloor, leaving 66% of planet Earth unseen.

Really enjoyed the discussion on communicating tipping points at NASA GISS! It’s a tough topic, but I agree with the panel—we can do better than we have so far. Thanks for organizing it @aromanou.bsky.social and colleagues!

Compound events in the (subsurface) ocean and how they change under climate change. 👇

Natacha Le Grix@natlegrix.bsky.social · last yr.

🌊🔥 Marine heatwaves often do not occur in isolation—they frequently coincide with extreme conditions in ocean acidity and oxygen levels. In our new paper, we assess the distribution and projected changes of these compound ocean extremes within the top 2000 meters of the ocean.

Here a new point of view on the response of the global ocean to climate change. In short: we cannot separate temperature from the rest when we look at trends in the dynamics. It is just a starting point. With the great Bruno Buongiorno Nardelli. www.science.org/doi/10.1126/...
