I was very happy to attend the Cello conference in Hamburg this week! 🌊

One day full of scientific discourse and networking: We used our time at the CLICCS Retreat last week to share the latest research and gather our forces for the next funding phase. Also, we honored our new Köppen Award Winner Youssef Ibrahim - congratulations!

In our new paper we discuss how communication of post-net zero climate changes needs to improve and go much further than global average temperature @chrisd-jones.bsky.social @sarahinscience.bsky.social @21stcenturyweather.bsky.social www.nature.com/articles/s43...

New paper alert! 🚨🧪🌊 Do you wonder how Southern Ocean sea ice changes decades after the AMOC substantially weakens? 🧊 Check out our new @jgroceans.bsky.social paper, amazingly led by Rachel Diamond from the @bas.ac.uk doi.org/10.1029/2024... Here is a quick summary 🧵 (1/n)

📝 Check out this Kudos summary of our recent ERL study on European heat extremes in long-term net-zero emissions futures! 🧪 link.growkudos.com/1pm179ta9kw

🌡️ Europe’s #heat extremes won’t stop, even at net-zero. Each year of delay locks in hotter and more frequent extremes for centuries. Mediterranean heatwaves could even be 30x more likely if the Paris Agreement is reached ten years late. 🧪 iopscience.iop.org/article/10.1... @edualastrue.bsky.social‬

Fantastic colloquium today by @eleanorfrajka.bsky.social on the state of knowledge of AMOC observations 🌊 It’s incredible & fascinating how far the field got in the last 20 years 💡 But also, how much there is left to understand & the need for more collaborative AMOC community 🤝

🚨 New paper alert! 🧪 🔥 How would heat extremes in Europe evolve under long-term net-zero emissions? Find out in our ERL article, co-written with @andrewkingclimate.bsky.social and Tilo Tiehn iopscience.iop.org/article/10.1... Here’s a quick summary (1/n) 🧵

🌍✨ Yippee! CLICCS will receive funding for another seven years as a Cluster of Excellence @uni-hamburg.de‬ ! Over 200 international researchers are exploring which climate futures are plausible—and how we can work towards achieving the desired ones. www.cliccs.uni-hamburg.de/about-cliccs...

Are you at #EGU25 and are interested in European heat extremes in Europe? 🌡️Perhaps in net-zero futures? 🏭 Or in climate stabilisation? 📉 Come to my talk tomorrow during the first morning session, at 9:45 in room 0.31/32! meetingorganizer.copernicus.org/EGU25/EGU25-...

What better way to prepare for #EGU25 than to calculate the mean temperature in Vienna during the conference for each year since the @egu.eu was established 🤓📈 Considering the current weather forecast for next week, this edition we might have a record year 🌡️

Despite staying below 2024-levels for most of April, daily global temperatures reach a new record for this time of the year 📈🌡️

It was a huge honour to attend today’s symposium for the 50th anniversary of the Max Planck Institute for Meteorology! 🎂 It’s so fascinating to see how important the institute has been for climate research, and also very exciting to look at what’s still ahead! 👏🏻

Although global mean temperature has cooled down slightly with respect to March 20th, it's now three days in a row (March 20th- 22nd) with unprecedented record temperatures for those days of the year 🌡️🌍🌊 Credit: C3S/ECMWF @copernicusecmwf.bsky.social

Sea surface temperatures for March 20th are below 2024 values but are still the second hottest ever for this day (20.94°C, 0.40°C anomaly wrt 1991-2023)🔥🌊 SATs spatial signal has large temperature anomalies over Central-East Asia, Eastern N. America, North-West Africa, & Eastern Weddell Sea coast 🌍

In this open review paper with @climatenerilie.bsky.social , @edualastrue.bsky.social and Tilo Ziehn we argue that the slow nature of some changes in the climate necessitate longer model projections at net zero emissions. egusphere.copernicus.org/preprints/20...

[Video] AMOC-Schwächung könnte Billionen kosten. Die #AMOC-Abschwächung verringert die #CO₂-Aufnahme, verstärkt die Erderwärmung & erhöht die Kosten - so die neue Studie von @felixschaumann.bsky.social & @edualastrue.bsky.social (MPI für Meteorologie). Carolin Riethmüller fasst für Euch zusammen➡️🔗

Last week, our @pnas.org paper titled “Weakening AMOC reduces ocean carbon uptake and increases the social cost of carbon” was published! 🎉🌊 It was so much fun and such a privilege to work with the amazing @felixschaumann.bsky.social 🥳

Climate change could weaken the Atlantic Meridional Overturning Circulation (AMOC), which would cool the Northern Hemisphere. A weaker AMOC could also diminish ocean carbon uptake, thus increasing the social cost of carbon. In PNAS: www.pnas.org/doi/10.1073/...

Check out this great paper by @felixschaumann.bsky.social with @edualastrue.bsky.social out now in @pnas.org that integrates climate science with climate economics to study the social cost of carbon implications of reduced AMOC weakening. Super impressive work for a first PhD chapter👇

💰 Weaker ocean circulation may cost trillions A new study by @felixschaumann.bsky.social and @edualastrue.bsky.social in @pnas.org reveals that a weakening Atlantic Meridional Overturning Circulation (AMOC) could lead to costs of several trillion euros. #CLICCS #climate #ocean @uni-hamburg.de

🚨 First PhD paper in @pnas.org 🥳 🌊 @edualastrue.bsky.social and I looked at how much less CO2 will be taken up by the ocean if the #AMOC weakens - and how this reduced ocean carbon uptake affects the social cost of CO2 emissions. 📝 Read the paper here: doi.org/10.1073/pnas... 🧵 A thread [1/11]

We just got the chance, at the MPI-M/@cenunihh.bsky.social joint seminar, to listen to Jochem Marotzke, director of the MPI for Meteorology, discussing the 1.5°C goal. These were his main points 🧵👇 1/n

Given the terrifying dismantling of diversity programs in the US, I think it is a good time to recap some climate science diversity initiatives in Hamburg, as last summer's visit of expert science writer and communicator @lisampmunoz.bsky.social. www.cliccs.uni-hamburg.de/about-cliccs... 🧵 1/7

Yesterday, I had the pleasure of attending, along with a few hundred other climate scientists in Hamburg, the colloquium from @geomarkiel.bsky.social's Prof Mojib Latif on the question of an AMOC slowdown 🌊 What were his main takes on the topic? 👇 1/5

Let’s start the new year in #Bluesky by reposting this starter pack of #AMOC scientists 🌊 Hopefully we can get some new faces included in it!

Lately, even sunsets seem to remind me of @edhawkins.org’s warming stripes 🌅 #ShowYourStripes

There are so many cool starter packs around here 💙 But I have not seen yet any specifically on the AMOC, so I decided to create one now 🌊 Let me know if you want to be included too! #AMOC #Atlantic #OceanCirculation go.bsky.app/JxFDh6b

The Max Planck Institute for Meteorology asked me a few questions about my current research stay with @andrewkingclimate.bsky.social at the University of Melbourne 🌏🇦🇺 You can read a bit about it on LinkedIn!👇💻 🌐
