Getting increasingly interested in the application of complexity economics to climate risk. I wrote an open-source agent-based model that embeds a heterogeneous set of agents in different climate scenarios, showcasing the need for ABMs in climate risk assessments.

Current scenario analysis and stress testing frameworks often ignore systematic risks of physical climate risk in the context of the wider economy. I make a case in this point about why we are underestimating physical climate risk. Let me know what you think! open.substack.com/pub/yaramo/p...
We are underestimating physical climate risk
Current scenario analysis frameworks often ignore important systematic risks.

Econometric climate models show a wide range of results, from single digits to 30-40% GDP loss for the same climate scenario!
In my latest post, I make a case for moving beyond simple empirical functions to a complex-systems approach for a more robust framework.

Why we need to rethink climate econometrics: from empirical functions to complex systems
The more I study the frontiers of climate econometrics, the more shocked I get at how limited existing models are for something with such enormous consequences.

Spent the week with Far Away Projects on Horseshoe Reef (Florida Keys). Water temperature was in the 30s C / 90s F. Saw coral bleaching in action and fish dying from heat stress.
I can’t describe how beautiful the reef ecosystem was. We must really do more to protect them!

If you view the Vision Pro as a toy, then sure the price tag is too high. But if you see it as an alternative for everyone to have their own designated home theater, home office, gaming room, etc. for a fraction of the price then $3500 is still much cheaper than the alternative!

Improving Mathematical Reasoning with Process Supervision
We've trained a model to achieve a new state-of-the-art in mathematical problem solving by rewarding each correct step of reasoning (“process supervision”) instead of simply rewarding the correct final answer (“outcome supervision”). In addition to boosting performance relative to outcome supervision, process supervision also has an important alignment benefit: it directly trains the model to produce a chain-of-thought that is endorsed by humans.
