Netflix schauen, Tropenfrüchte essen, Billigmode tragen – die meisten Treibhausgas-Emissionen entstehen durch importierte Güter und Dienstleistungen. Eine Tagung an der Universität Bern rückt diese «grauen Emissionen» ins Zentrum. Donnerstag, 30. Oktober. www.uniaktuell.unibe.ch/2025/klimasc...

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👇

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

The massive extreme marine heatwave continues to stretch across the entire northern Pacific Ocean. In fact, the magnitude of the sea surface temperature anomalies even grew in August 2025 compared to earlier in the summer. Yikes... 🫠 Data from OISSTv2.1 (psl.noaa.gov/data/gridded...). 🌊

Here‘s a rare and excellent career opportunity for outstanding physical oceanographers at the Potsdam Institute (PIK) and the University of Potsdam, in beautiful surroundings just outside Berlin. Tell qualified friends or colleagues! 🌊 www.nature.com/naturecareer...

🌊 Nacht der Forschung 2025 | University of Bern 🌊 What a fantastic evening! Thank you to the entire ocean modeling team and friends for their incredible effort. For one night, the Kuppelraum transformed into a "true" ocean, full of energy, visited by many, and filled with inspiring conversations.

New work by Lester Kwiatkowski and colleagues suggests that the reduction in coral reef calcification due to climate change may end up enhancing the ocean carbon sink by up to 1.25 Gt CO2 yr-1 by mid century (by even more by 2300) 🌊 www.pnas.org/doi/full/10....

My co-chair François Houllier and I are delighted with this resounding success, after 2 years of preparation and many hurdles to overcome. The recommendations will be presented to Heads of State and Governments tomorrow, the day before #UNOC starts. #OOSC #ScienceForTheOcean

The One Ocean Science Congress has started! Exciting four days ahead #OOSC25

Our new paper authored by the Scientific Committee of the #OOSC on "US federal cuts threaten international ocean science and diplomacy" has been published. www.nature.com/articles/s41...

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.

#standupforscience2025. The sidewalk open house and NASA GISS swag giveaway is on at 2880 Broadway NY NY til 4 pm ET. Photos from a NASA scientist. 🌎🧪 matters.

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’.👇

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/...

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. 👇

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/...

Am 29. April sprechen Alexander Proelss und Thomas Frölicher über „Meeres-Wissenschaften und Internationales Recht im Klimawandel“. 🗓️ 29. April | 🕓 16:15–17:45 📍 Hörsaal 001, Kollegienhaus, Universität Basel

🌊🌡️ In this study published @natcomms.nature.com, we analysed the simultaneous occurrence of marine heatwaves with extreme events of high acidity and net primary productivity in the equatorial and South Atlantic. Why is this important? A short 🧵... www.nature.com/articles/s41...

Compound event frequency strongly increased over the past two decades in the South Atlantic. New study led by @rrrocean.bsky.social 👇

🌊 The N.Atlantic has been experiencing extreme T°C in 2023. This situation raises a number of questions: Have we missed something? Do climate models allow us to understand such an event, or have we entered a new climate regime? We attempted to answer these questions in this study: rdcu.be/eh0e8 1/14

Tonight the Eiffel Tower turned blue to mark an SOS for the Ocean! ahead of #UNOC3 and the #OneOceanScience Congress in Nice, June 2025. 🌊 sos-ocean.com

Does the ocean warm when the AMOC weakens? 🌊 Our new ice-core noble-gas data say it does, at least during the last four deglaciations. A warmer ocean stores a lot of energy but also expands and has lower solubility, which has implications for CO2, sea level, and climate. doi.org/10.1029/2024...

Enjoyed the stimulating discussions in Paris at the 3rd International Scientific Committee meeting for the One Ocean Science Congress. Excited for the Congress in Nice this June & hopefully strong, science-based outcomes from #UNOC3! Thanks @jpgattuso.bsky.social & François Houllier for organizing!

A new estimate of the composite model-based estimate of the annually averaged ocean carbon sink. 🌊 This composite model-based estimate of the ocean carbon sink from 1959 to 2022 is similar in magnitude to the best estimate of the Global Carbon Budget but 70 % less uncertain.

Was bedeuten die Kürzungen bei der Wetter- und Ozeanbehörde @noaa.gov für die Wissenschaft und insbesondere für die Ozeanographie? Meine Einschätzungen im neusten #Wissenschaftsmagazin des Schweizer Radio. Vielen Dank für das Interview Katrin Zöfel. www.srf.ch/audio/wissen... @unibern.bsky.social

The large increase in sea surface temperatures in 2023-24 was anomalous, but not completely unexpected when applying climate models, according to research in Nature. https://go.nature.com/3R5Hmqk 🧪 🌊

Key takeaways from our study on the record-breaking global sea surface temperature jump in 2023-24: • A rare 1-in-512-year event • Only possible due to human-caused global warming • Climate models capture it—no signs of unexpected climate change More details below 👇

📢 Postdoc Opportunity: Ocean Tipping Points & Impacts! We're hiring a postdoc in my group at the University of Bern, Switzerland, to study ocean tipping points and their impacts. The position is part of HEurope project TipESM (@tipesm.bsky.social). Feel free to reach out with any questions. 🌊

Had a great time teaching superconductivity to physics undergrads today! Always a pleasure having experiments accompanying theory - huge thanks to our lab experts for their great experiment preparation! #Physics #Superconductivity @unibern.bsky.social

This is really sad news. NOAA GFDL is one of the world's leading climate modeling centers, home to exceptional scientists. If anyone directly affected needs support, I’m happy to help. www.science.org/content/arti...

Impacts from marine heatwaves call for proactive early warning and response strategies www.nature.com/articles/s41...

Dear US colleague scientists exposed to multiple unprecedented pressures on academic freedom, up to brutal and unfair firing, I do not know how to best help you in these horrible circumstances. You are not alone.

There’s growing concern that we may (temporarily) overshoot the #ParisAgreement’s 1.5°C target. But what does this mean for marine life in the long run? Until now, we’ve had limited understanding of how stabilization & overshoot scenarios impact marine species🧵👇🌊 bg.copernicus.org/articles/22/...
