Climate models since the 1970s nailed it—most predicted global warming almost exactly as it happened.

There’s a famous chart from the Conservation Research Institute, which demonstrates this. GAZE UPON THESE ROOTS, YE MIGHTY AND DESPAIR.

Heading to the AOM Meeting in Copenhagen? Interested in Climate Risks, Risk Perception, and Risk Management in the Supply Chain? Stop by my poster presentation on “Value Chain Dependencies and Climate Risks in the Value Chain”. @ifmbonn.bsky.social #AOM2025 #ClimateRisk #RiskPerception #EconSky

#EU manufacturing broadly outperforms the rest of the world in #productivity terms, but the industries in which it specialises are not always those in which it is relatively more productive. Policy should target weak #trade sectors. F Di Mauro, M Matani, G Ottaviano cepr.org/voxeu/column... #EconSky

The Nievas-Piketty unequal exchange paper is certainly better than Hickel's, but their counterfactual assertion of convergence between countries in 1800-2025 is based on these entirely political-economy-free assumptions

I have cleaned a bit my lecture notes on Optimal Transport for Machine Learners arxiv.org/abs/2505.06589

I couldn't agree more! The excessive focus on linearized solutions to HA models is a bit like the old joke about the drunk who is looking for a key under a lamppost because that's where the light is. More discussion of why we need non-linear models and ways forward here benjaminmoll.com/challenge/

As @shengwuli.bsky.social always says, when you notice the network theorists getting really excited, you're probably in for a bad time.

The code from my #JMP is now available here: github.com/NoFishLikeIan/carbon-tipping-point #EconSky: if you are interested in stochastic optimal control problems, #JuliaLang or the climate, read further!  🧵

A while ago Alex London and I noticed that many of the objections to utilitarianism depend on a utilitarian being in a world of non-utilitarians. There would be no forced organ harvesting in a world of utilitarians. People would line up to volunteer. ...

This inequality says that if y=φ(x) is a continuous, strictly increasing function of x, for x≥0, with φ(0)=0 then (note φ^{-1}(y) is the function inverse) 2/

Discretisation memes! 😊

Since a few more people decided to follow me in the last week (👋 and 🙏), let me re-up my #EconJMP, maybe using the right hashtag this time! #EconSky If you are interested in climate economics and tipping points, check it out: bsky.app/profile/nofi...

Advertising for a PhD position at Oxford working with me and Tad Komacek. Project is on climate modelling using automatic differentiation with Enzyme in SpeedyWeather.jl applied to Earth and exoplanets. Plenty of space for ML/GPU/HPC/data visualisation projects within that PhD position too!

Got my first paper rejection after a few months of review. But two great reports came with it. Time to dive back in... 🤿 After the job market... 😢 #EconSky

Economics hasn’t fully internalized how difficult climate tipping points are to both predict and reverse. My JMP 🚨 estimates the costs of this unpredictability and irreversibility. A thread! 🧵 (1/14) #econjobmarket #econjmp #econtwitter #climate

Copilot taking the piss.
