Key quote for me: “an entire profession might gradually lose its capacity to question and redefine its goals, because AI systems embed assumptions about what those goals are.”

Smart take on the (hidden) costs of AI, and what to do about them. The intro alone: 🧐 www.nature.com/articles/d41... @nature.com

An analysis that meets the moment

There are genuinely few things better to cap a day at the office than a bike ride home through Central Park. It helps that office = classroom with 90 engaged @columbiabusiness.bsky.social & @climate.columbia.edu students talking Climate Risk. Today's topic: insurance.

Something to be said to put the full quote on the cover. US v UK edition.

*fossil energy crisis And yes, that means pushing EVs (and cycling, for that matter) to get off oil (even) faster, and pushing renewables and batteries and heat pumps and home retrofits and industrial electrification and … to get off gas.

On top of the hour, we'll have Chuck from Tallahassee join us to sort through the evidence and help us make sense of this vital debate. Stick around.

French President Macron: “Europe is an extremely attractive continent. For months I’ve been saying this. And thanks to our American friends, I now have an unprecedented selling point: We are predictable.”

That's tens of thousands of authors whose submissions can be desk-rejected from here on out, leaving some more room for the rest of us. www.nature.com/articles/d41...

Yes. Yes, it will. www.ft.com/content/bc95...

Perennial reminder: IKEA sells induction plates for $50. Cap the gas line, put the induction plate on top of the gas stove, and avoid spewing carcinogens into your home. Yes, you can also spend $5k on that beautiful high-end stove, while vying for that Michelin star. www.ft.com/content/14f6...

🎓 6 lessons I learned on spring break. Actually, it's 20 pictures of one of the more amazing, educational weeks: www.linkedin.com/posts/gwagne... Let's just say spring break doesn't typically involve tours through steel plants, nor meeting @thyssenkruppsteel.bsky.social & Etex CEO before the tours

Green Pledge: "By 2030, Global Tetrahedron will hire a vegetarian cleaning lady." Ouch.

Trump subtracts $50 billion from Big 3 in Detroit, adds $70 billion to Big 3 in China.

"Experts prefer heat pumps, but homeowners have doubts" I wonder who sows those doubts, contrary to any evidence.

Fun with AI gwagner.com/AI

Wealth = a society that invests in public(!) infrastructure for the benefit of all. Yes, that building in the back is the former Shell HQ. Yes, the Netherlands chose to leave >€400 billion of gas underground in Groningen, and yes, that meant handing €150b to Putin. Yes, that was a mistake.

Swedish gov't report had to be withdrawn due to non-existent references: "We don't know what happened." Meanwhile, literally everybody knows what happened. #AIslop

Hm, not particularly. I realize saying "it's complicated" is the erudite thing to say, but yeah, the more solar PV on your roof, the lower your exposure to geopolitical price volatility and #fossilflation. Of course, only going fully off grid will shield you from all oil & gas price volatility.

Idly wondering if this time, the media will clearly identify "fossilflation" as the reason for higher prices for everything as we discussed with @gwagner.com back in Ep. 221 in 2024 xenetwork.org/ets/episodes... or if the talking heads on CNBC will blithely carry on as if it's all about Fed policy.

What a paragraph. www.bloomberg.com/news/article...

Turns out both can be true at the same time

The Loneliness of Sonja and Soccer.

I'm no longer quite sure how to do this without just saying "Duh!" Yes, getting people to pay the "green premium" is sometimes tough. Guess what, the "security premium" is a lot higher. The answer for both climate and security — and for economic competitiveness, too — is to get off fossil fuels.

India has a once-in-a-century opportunity to become a global energy superpower. Not because of oil or gas. Because of solar, wind, storage, and hydrogen. A $1T India New Energy Transition Fund could turn energy imports into energy exports. 🧵

Ok, BSky, help me beat my 15-year-old in this.

Keeping this for next time someone says "but the green premium." Or "sure, climate, but 'value' creation." Or "intermittency!"

"Decadal time scale" is literally what anyone proposes here: "Reaching net zero by 2050..."

The prescription to #fossilflation? Get off fossil fuels. "Reaching Net Zero by 2050 'cheaper for UK than one fossil fuel crisis'"

Had to do a triple-take on this one. Some are reacting to volatile oil prices by getting an EV. Some others: "Monday, Wednesday, Friday: illegal to fill up gas tank" Outdated tech, meet outdated economics. Not from the Austrian @theonion.com

If you read one thing about Iran & geopolitics & economic fallout & climate, make it this @martinsandbu.ft.com column

Oh, academia. "All Reviewers Assigned", 3½ months after first submission. And that's for one of the 'better', more professionally run journals.

Having mastered epidemiology, Russian history, toilet paper supply chain logistics, bridge design, balloon aeronautics, and large language models, I'd like to offer my thoughts on how the closing of the Strait of Hormuz will impact Brent crude....(1/67)

Turns out the 15-year-old created a python program that solves the @nytimes.com Spelling Bee every day in a matter of minutes. 🥹 "Could do it in seconds, but I slowed it down so they don't think I'm a bot." 😎

This is what ecocide looks like.

Enshittification, recycling bin edition. Yep, it all goes into one trash bag. The worst part, of course, is the general cynicism this breeds.
