- Is "overshoot" replacing "tipping points" in the climate discourse? I wrote a short blog post exploring this idea. Bottom line: it's all about urgency and irreversibility, but overshoot can circumvent some problems that the tipping points framing has. Read the full post here: s.gwdg.de/wRWft8

- Reposted by Felix Schaumann[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➡️🔗
- Reposted by Felix SchaumannClimate 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/...
- Reposted by Felix SchaumannEconomic impact studies tend to find a weaker AMOC globally beneficial, as lower temperatures in the Northern Hemisphere would offset some global warming & associated economic damages - but new paper shows this ignores reduced C uptake by oceans & Social Cost of Carbon.

- 💰 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
- Reposted by Felix SchaumannDer Kollaps einer Meeresströmung könnte Europa extrem kalte Winter wie in Kanada bringen, warnten Forschende zuletzt. Unwahrscheinlich, sagt eine neue Studie. Was stimmt?
- Reposted by Felix SchaumannCheck 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👇
- 🚨 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]

- [2/11] Why is this relevant? Existing economic impact estimates deem AMOC weakening globally beneficial. Why? Because a weaker AMOC would reduce temperatures in the Northern Hemisphere and thereby locally offset parts of global warming and the associated economic damages.
- [3/11] But what about all the other climate impacts that AMOC weakening would have, beyond just surface temperatures? They have yet to be integrated into economic impact assessments, and we start by looking at the carbon cycle.

- Reposted by Felix Schaumann#AcademicSky Maybe dealing with GPTs hallucinating papers should give us a reason to update our 20th century approaches to article referencing. Can't we just use the DOI when writing papers and stop pretending that anybody is going to go to a physical library to find a specific journal volume?

- Reposted by Felix SchaumannStarting 250 years ago, we began putting lots of carbon that was buried underground for millions of years into the atmosphere. All in all we’ve emitted nearly 2 trillion tons of CO2 from fossil fuels, which is more than the total mass of the biosphere or all human structures:
