I’m for some things and against others

Nice! Would be cool to see the margin difference on the vertical axis in the second fig.

In the Energy Institute blog this week, Meredith Fowlie has an excellent explainer about what the IRA is really likely to cost per ton of GHG reduction based on a new paper from EPRI.

My working paper with @bistline.bsky.social is the subject of today's @ucenergyinstitute.bsky.social blog post by Meredith Fowlie. Honored!

BTC is a computation treadmill.

Jensen's paradox (⬆️efficiency=>⬆️demand) is weak for many things (cars, lights) bc demand is inelastic. Not so for crypto mining!

Makes sense. Miners mine until marginal cost=marginal benefit. ⬆️eff=>⬇️mc=>⬆️mining=>⬇️mb. An EPRI brief: www.epri.com/research/pro...

A PhD implies someone is capable of advancing knowledge, of learning and sharing things about the world that humans have not previously known. A generative AI model, by definition, cannot do this.

It's important to cover all the bases

As expected, the Trump team is already deleting climate info from government websites. In anticipation, our team at Urban Ocean Lab created a permanent archive of 100+ key resources and published a permanent archive: www.urbanoceanlab.org/resource-hub 👩🏽‍💻

We show, among other things, that climate attribution among R House candidates depends on district-level climate vulnerability and fossil fuel employment reliance

Waste of paint! Guernica has stopped exactly ZERO wars.

And who shifted their opinion? Was the shift highest for folks with baseline opinion in the middle or the extremes. I would have scored high in climate concern and the film did not change my mind, but it's not folks like me who matter.

Changes in a 100 point scale doesn't mean anything to me. It definitely doesn't mean a 4.5 percentage point change in voting behavior (which would be gigantic). How should I think about this magnitude?

I like art. It makes me think and feel things. I don't expect single works to have measurable effects on opinions. But! In the case of don't look up it did (in a non-peer-reviewed RCT). Which is cool and leaves more questions..

The difficulty with interpreting these numbers is that this 100 point scale doesn't mean anything to me. I'd rather know who shifted. Specifically if the folks with a lower baseline shifted more than the higher baseline folks.

I'm pleasantly surprised that there is an effect! My guess would be that there is no effect on ppl who already think CC is a problem. I didn't change my views. If so, that 4.5 point change is being diluted by the already converted.

I may be too literal

And Ds should have been freaked out after the close win in 2020 and the apparent loss of the coalition.

I didn’t realise BlueSky has no algorithm (so you see what’s actually there) - and that you can choose your own filters for feeds.

This one’s lovely: people you follow but post infrequently, so it boosts quieter, interesting types. I’ve added it to my feeds and it’s great.

Last dude tried to tell me that EVs have special insurance that my insurance wouldn't cover. "So you just want to pay for it if something happens while you're charging?"

Why is this simple thing so terrible? Help @pjvogt.bsky.social

Are low-cost car rental companies just a scam to get folx to buy overpriced insurance?

The hours of waiting in line, agents who disappear for 20 min in the middle of checking u out feel designed to wear u down when they threaten financial ruin. And u don't need it if u have almost any credit card.

This has got to be it with so many states having minimum injury liability around $25k. It would be interesting to compare MI ($50K) to its neighbors (all $25k).

I'm confused if this is a problem with how inflation is measured. (Obvi an issue with higher costs and risks). Higher insurance costs get passed on to renters and BLS uses "owners' equivalent rent of primary residence" for home owner costs--what they would pay if renting.
