"The central methodological implication is that, in climate finance, stability should be treated as an outcome to be investigated rather than an assumption imposed at the outset" These are "ruled out or strongly constrained in conventional equilibrium IAMs" academic.oup.com/imaman/advan...
Here we go again: the misuse of models and the looming climate crisis
Abstract. Climate-related financial risks are characterized by path dependence, non-linear feedbacks, regime shifts and the possibility of endogenous insta

Sun breaking like a jewelled egg over the chill, windy hills this morning.
Did the buried village and the waterfall and now off to the hot springs for another walk! Been a gorgeous day for sightseeing!

Decode every shot twice: fast in real time, then with a slower, more accurate decoder afterward. Where they disagree, a logical error is likely. Discarding those shots still leaves a bias. Our new preprint keeps them, with negative weights, which cancels the bias on average.
DINOv2 has never seen a caption, and Qwen3 has never seen an image. We still aligned their embedding spaces without a single image-caption pair. It even works when the images and the captions come from different datasets. Project page: dominik-schnaus.github.io/unpaired-rosetta ⬇️
This is a result I’ve dreamt about for many years: *unpaired translation between images and text* I thought it might be only slightly possible, the kind of thing you have to really squint at. But Dominik proved this wrong. You don’t have to squint. Worth looking for yourself:

These results surprised me. There's more to do to fully understand which structures align! Here are some great readings on other perspectives: * local relational: arxiv.org/abs/2602.14486 * coarse-grained: arxiv.org/abs/2604.18572 * global relational: arxiv.org/abs/2609.27252 n/n
In PRH, we argued that rep geometry is converging, but it's still an open question exactly in what sense. I want to share some new evidence that might clarify the picture. The evidence comes from our work here, led by @schnaus.bsky.social: dominik-schnaus.github.io/unpaired-ros... 1/n
Hello, @animalphotorefs.bsky.social lost their job midway through the trip that's supposed to pay for the trip and is now stranded so far away. If you could benefit from animal photos for art references, please consider supporting.
Animal Photo Reference Repository@animalphotorefs.bsky.social · 3d agoI just found out I’m losing my main source of income because AI search has nerfed the revenue of my main client. I am, also, 2000+ miles from home doing photography I expected to pay for with that income. If you can help, I’m hoping to raise $1000 to help cover trip costs & the drive back west.

Yellow-throated Warbler (Setophaga dominica) for the alt #BirdoftheDay theme #Perched. I saw my first one of the season in the backyard today.
Good night. wasn't going to post but couldn't let this water theme pass. ⚓ #BirdOfTheDay #BlueWater Alt #Perched #birds #photography #ColorADay #RedWed
Love blue flowers and even more when mixed with grey. These little guys are happy in the cooler weather!

ah damn, RIP Margaret Hamilton. she took safety-critical software engineering seriously, and got people to the moon and back. news.mit.edu/2026/margare...
