🌊 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.

Have you ever wondered why a landlocked country like Switzerland should care about the health of the ocean? Check out our new 2-pager👇

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

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!

Angriff auf Wissenschaft – US-Gelder in Forschungs­projekten – Uni Bern nervös www.bernerzeitung.ch/universitaet...

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!

Exciting hours ahead: Introducing the Tesla coil today to the students @unibe.ch .

📢 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

Species adaptation could mitigate some of these long-term effects, but it all depends on their ability to keep up with rapidly changing conditions.

Even in overshoot scenarios, the worst impacts can occur more than a century after peak warming.

Our findings show that only half of the total habitat loss is realized when a temperature stabilization target is first reached.

Mein Buchtipp für alle, die das Meer lieben (#Pragmaticus)👇

Looking very much forward to the upcoming symposium on past knowledge and future directions in climate and environmental physics, and celebrating the huge scientific contributions of Fortunat Joos, Markus Leuenberger anf Thomas Stocker

The simulations also indicate that meting the 1.5°C warming level requires a 40% reduction in CO2-fe emissions from 2025 to 2030, a 98% reduction from 2025 to 2050, and a stabilization at +1.0 (!) Pg C yr-1 from 2100 onward after the 1.5°C global warming level is reached.

The study also shows that the remaining carbon budgets evolve substantially over time, potentially doubling compared to the initial estimates.

We show that the remaining carbon budgets for the 1.5°C and 2.0°C global warming levels are about 60% larger than the median estimate from the IPCC AR6. The study also highlights that some of the differences are attributable to the choice of non-CO2 mitigation scenario.

We show that by applying the adaptive emissions reduction approach (Terhaar et al. 2022, NCC), it is possible that all models converge to the preset temperature level

Marine heatwaves (MHWs) don’t just harm ecosystems—they also alter the ocean’s carbon cycle! Our new analysis of 30 global datasets shows ocean CO₂ uptake drops by 8% during MHWs, with regional anomalies reaching up to 30%. 🌊
