🌊 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 👇

🌡️ 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
A photo of the lead researcher Eduardo Alastrué de Asenjo and a quote: “The bad news: Even if we were to stop emitting greenhouse gases immediately, extreme heat in Europe would continue to occur. The good news: The sooner we achieve net-zero emissions, the sooner we can prevent extremes from getting even hotter for centuries to come. Every year counts.”

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/...
Overview of the modeling approach. (A) The Max Planck Institute Earth System Model is used to simulate climate states with an artificially weakened Atlantic Meridional Overturning Circulation (AMOC). (B) The resulting changes in annual ocean carbon storage are then analyzed as a function of the simulated AMOC. (C) The strength of the AMOC carbon feedback is estimated until 2100. (D) The economic impact of these projected changes is then analyzed.
