Interested in climate change and all the science around it - PhD candidate in climate economics at ETH Zürich. Mainly working with IAMs. also @felixschaumann@mas.to, @felixschaumann@twitter

🌊 Finally, there will be an #EGU26 session about the AMOC! Specifically, about the impacts of AMOC weakening, very broadly defined - from paleo to the future, form observations to modelling, from physics to economics, ... Please do submit - Looking forward to a great session 😊 More details 👇

Planning to attend #EGU26? Interested in the impacts of AMOC weakening? New session alert! 🚨🌊🧪 ITS2.5/CL0.5: "AMOC impacts: physical, biogeochemical, and societal" Check out our interdisciplinary session description & submit your abstract here: meetingorganizer.copernicus.org/EGU26/sessio...

Economic 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

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👇

🚨 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]

No cheers for warming slowdown from potential weakening of AMOC given carbon drawdown impact. New study.

Die Abschwächung der #AMOC bietet neben den bereits oft prognostizierten Abkühlungseffekten für Nordeuropa weitere spannende Skills: Sie wird wohl auch die CO2-Aufnahmekapazität des Nordatlantiks verringern. #Klimakrise #Nordatlantik #Ozean #Ozeanographie

Excited to announce a new @pnas.org publication on the Social Cost of Carbon. We integrate evidence from the literature and expert survey to provide an SCC distribution inclusive of both parametric and structural uncertainties. Our mean 2020 value is $283 per ton CO2 www.pnas.org/doi/10.1073/...

Synthesis of evidence yields high social cost of carbon due to structural model variation and uncertainties | PNAS

Estimating the cost to society from a ton of CO2—termed the social cost of carbon (SCC)—requires connecting a model of the climate system with a re...

Softening the definition of Net Zero won’t stop global warming. As authors of the 2009 “Net Zero Papers” we call on countries and companies to recognise the need for Geological Net Zero, balancing flows of carbon into and out of the Earth’s crust. www.theguardian.com/environment/...

Countries could use nature to ‘cheat’ on net zero targets, scientists warn

By relying on natural carbon sinks such as forests and peatlands to offset emissions, governments can appear closer to goals than they actually are

#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?

Ben Sanderson@benmsanderson.bsky.social · 2y ago

I feel like this is another good argument for a better approach to referencing in articles. If the DOI was used throughout, rather than journals still insisting on increasingly irrelevant volume/issue references - we could potentially sidestep this issue of GPTs bullshitting nonexistent papers.

Starting 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:

Interested in economic effects of AMOC weakening? Join us tomorrow afternoon in #EGU24 session CL3.2.3 to hear about how the AMOC affects the carbon cycle and through that the social cost of carbon! Also if you just want to hang out and talk climate economics, anytime! :)
