Over 2 million people across Italy have rallied in more than 100 cities for a one-day general strike.

The oceanic physical injection pimp of organic carbon. New paper, done with some good old friends. Note the proposition of a horizon surtace for the carbon export that combines mixing with light penetration.

Amazing animation of tankers burning oil to move oil

Bottom trawling is horribly destructive to coastal ocean ecosystems, and deep-sea mining will do the same to the open ocean. #OceanFilm 🌊

I helped draft this open letter about last Friday’s gold standard science executive order. Take a look and consider signing if you agree.

This is phenomenal. Sea surface temperatures are >5C above average to the west of the UK and around Iceland. It's the strongest area of anomalous warmth on the planet at the moment. It's the warmest in recorded history for northwest Europe.

NYU has been up there with Columbia for complicity. Just appalling stuff.

@altagliabue.bsky.social making a presentation at @ucl.ac.uk telling us that ocean iron fertilization won’t do jack for climate and will further harm fisheries. Yet, it’s the marine CO₂ removal (mCDR) method that has sold the most credits so far. 🤷🏻‍♂️

"Behavioral Interventions Motivate Action to Address Climate Change" | Honored to be co-author on article in @pnas.org led by @penncssm.bsky.social post-doctoral scholar @asinclair.bsky.social sky.social w/ Emily Falk & others @upenn.edu @appc.upenn.edu @asc.upenn.edu www.pnas.org/doi/10.1073/...

Here a new point of view on the response of the global ocean to climate change. In short: we cannot separate temperature from the rest when we look at trends in the dynamics. It is just a starting point. With the great Bruno Buongiorno Nardelli. www.science.org/doi/10.1126/...

Why we need to embed environmental justice now more than ever in our teaching of geosciences, with some useful approach and case study examples

The densest water in the world ocean forms around Antarctica, and then spreads out to flood the global abyss. We’ve seen the production of this water dwindle over the past few decades, a change that is now impacting the North Atlantic. 🌊🧪❄️ www.nature.com/articles/s41...

This. 1000x this.

This work from @carbonplan.org is an incredible resource of open science. carbonplan.org/research/cmi...

This is a highly recommendable reading. I am very much enjoying @mitpress.bsky.social Terrence Sejnowski's book, written by one of the founding fathers of computational neuroscience and AI.

For those of us who are not professional biologists, it can be daunting to hear about transcription factors, signaling pathways and non-coding RNA. But this poignant piece from @philipcball.bsky.social opened my eyes to how deep and essential these ideas truly are. nautil.us/how-life-rea...

Happy Holidays from the SOCCOM (soccom.princeton.edu) and GO-BGC (go-bgc.org) projects. The present under the tree? 115 BGC-Argo profiling floats deployed this year and more at sea. All data freely available. Thanks to all the folks who made this happen and the US NSF for their support.

How does science work? Hypothesis-testing is only half the process and science also owes its progress to serendipity driven by data exploration. In the new Night Science Podcast episode we ask bold scientists about explorations. Check out some quotes below ⬇️ open.spotify.com/episode/0JvE...

Please join me in congratulating one of my favorite people @bopplaurent.bsky.social on his election to the French Academy of Sciences. 🌊 www.academie-sciences.fr/communique-d...

Indeed, congratulations!!!!

Not a new paper, but a new one to me. Thanks @chelseyabaker.bsky.social for drawing it to my attention (and to Sophia Johannessen and James Christian for writing it!). My eyebrows have been raised many times by #BlueCarbon claims so it's good to read a corrective ... 🌊 www.nature.com/articles/s43...

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/...

The ocean was unusually hot in 2023 👇 We found that this caused an unexpected decline of the ocean carbon sink, primarily driven by anomalous outgassing of CO₂ in the northern hemisphere extratropics. ▶️ doi.org/10.21203/rs.... Feedback on our preprint is more than welcome! 🌊

Some decisions are best made quickly and locally. Governance can work better as a higher-order network, not a pyramid around a central state. How should we design these networks? We looked at this with law and complexity scholars and found "effective governance" networks. arxiv.org/abs/2412.03421

In today's lecture in my nonlinear dynamics and chaos course, I tried to give intuition for where chaos comes from. It's caused by repeated stretching and folding of phase space.

Friends, colleagues, from #physics #ComplexSystems #Neuroscience #biology #evolution (biological, cultural,...), serious question looking for technical and well motivated answers if possible (ground for a future #ComplexityThoughts) : Is evolution an engineer, a tinkerer or an artist?

I think it’s time journals paid reviewers. Seriously.

My guess is that this post is a joke to 50% of scientists and serious to the other 50%.
