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...

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

🚨 We are hiring! I am looking for a climate scientist postdoc to join my team at Oxford working on a project on climate change and health until Feb 2028. For more details: www.linkedin.com/feed/update/... 📅 Apply by 14 May here: my.corehr.com/pls/uoxrecru...

[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➡️🔗

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/...

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. See bsky.app/profile/feli...

Der Kollaps einer Meeresströmung könnte Europa extrem kalte Winter wie in Kanada bringen, warnten Forschende zuletzt. Unwahrscheinlich, sagt eine neue Studie. Was stimmt?

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

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

🚨 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]

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/...

In a new interdisciplinary Nature Climate Change Perspective paper, led by me, @lisgilmore and Rachael Shwom, we offer a critical perspective on #climate and social “tipping points.” 🎁: rdcu.be/d2gBC 🧵

The model calibration paper for fair is now published in Geoscientific Model Development! 🎉 TLDR: how do we constrain a highly parameterised model to observational and assessed constrained ranges, with uncertainty? gmd.copernicus.org/articles/17/...

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

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/...

#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?

New article published today at Science Policy Forum, joint with co-authors Lisa Rennels, Frank Errickson, and David Anthoff www.science.org/doi/10.1126/...

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:

On The Climate Brink, I explain the problems with this graphic. In fact, climate models do an excellent job simulating the climate. www.theclimatebrink....

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! :)

Stoked to be at my first AGU next week! Check out my talk on Thursday on economic assessment of AMOC changes, and let me know if you wanna grab a coffee and talk science ☕🤓 #AGU23

This survey from 2009 is really a wild read. Most climate scientists surveyed thought 4-5C by end of century was the most likely, and that 2C was close to impossible to achieve. Imagine the results if you took this exact survey again today.... www.theguardian.com/environment/...

"Once we open the door to consider catastrophic change, a whole new debate is engaged...If we cannot reliably judge how potential geophysical changes will affect civilization, can we use the plain vanilla cost-benefit analysis (or even the Haagen Dazs variety in dynamic optimization models)?"

Today, our paper updating the amount of carbon we can release before breaching the Paris agreement temperature targets has been released into the world! Read it www.nature.com/articles/s41..., about it here: scienceisshiny.wordpress.com/2023/10/30/c...

NEW RESEARCH: Overall mining actually DECREASES substantially even when just accounting for coal. Mass of minerals for energy transition technologies is a fraction of mass of coal produced in current fossil-dominated energy system. www.sciencedirect.com/science/arti...

This year's record-setting Canadian fires burned >3 times as much carbon as all of Canada's annual fossil fuel use. Canadian fossil fuel emissions (2021): 545 MtCO₂ Canadian wildfire emissions (typical year): 290 MtCO₂ Canadian wildfire in 2023 (CAMS estimate): 1,740 MtCO₂

Hurray, @pythonmaps finally published the river basin map for my birth country of Germany. I was born and raised in the red part (even though it’s very black politically).

New on Deep Convection (and my first post on here): the Chief Scientist of NOAA, Dr. Sarah Kapnick! Sarah has had an amazing career so far, and we covered as much of it as we could in under an hour. What an honor for our little podcast! deep-convection.org/2023/10/09/e...

After wondering for years how to disentangle the interpretations of different parts in IAM welfare functions, today I learned how one can cleanly separate time preference and inequality aversion — great work!

What is common knowledge in your field but shocks outsiders? More than half the CO₂ emissions of the Industrial Age have been pumped into the atmosphere since 1990.

One critical question around climate tipping elements is the type of threshold behavior - do global temperatures need to only temporarily pass a critical level, or do they have to stay there for centuries. Thankfully for Greenland it seems to be the latter: www.nature.com/articles/d41...
