While we're all watching one too many AI ads, I just finished grading 60 student essays. Hard to tell for sure, of course, but somewhere between ½ and ¾ must have been fully AI generated. The AI check (shown to students at time of submission), and another Claude check agree.

Why climate change isn't about averages, it's about deviation from centuries-long past trends -- Winter Olympics edition

Q: What time is kickoff? A: The Bad Bunny concert kicks off around 8:00 or 8:30 p.m., but there will be pre-concert entertainment starting at 6:30 p.m. from one group called the “New England Patriots” and another called the “Seattle Seahawks.”

Things are about to get interesting at work

One of the more ambitious projections for Voluntary Carbon Credits I've seen of late: ~$50b by 2035, up from ~$1.5b today. Quick sanity check: Today's size of Europe's (compliance) market alone? ~$200b.¹ California's? ~$10b.² ¹ icapcarbonaction.com/en/ets/eu-em... ² ww2.arb.ca.gov/our-work/pro...

Hey @zohrankmamdani.bsky.social, minor request but one of these 'nudges' with outsized influence: @nyc311.bsky.social alerts have a near daily parking reminder. 90% of New Yorkers don't need that. Ask drivers to sign up for some special alerts only they need. Send flower emojis to the rest of us.

Sometimes I do miss that site. Oh, and yeah natural gas can clearly do no harm. It has natural right there in the name.

The word don't is censored. Don't, or Don T. If you're looking for just some fun proof they're doing control+f censoring

The thing, of course, is that some of these people will get through the nomination process, where they'll do damage for decades to come.

"warmer homes in the winter, cooler homes in the summer, lower emissions, and real climate action that improves people’s lives — starting with the communities too often left behind." Heat pumps FTW

"America's deeper question is whether or can restore a culture of shame"

More of this, much more. Yes, induction, and heat pumps, and properly insulated windows should be standard fare for any high-end home design www.nytimes.com/2026/02/03/r... And yes, there's a $60 induction plate at IKEA...

To commemorate Transit Equity Day and Black History Month, a seat has been reserved today to honor the legacy of Rosa Parks. Each and every day, we’re committed to providing accessible and equitable transit for all.

“And then we also have the best of the best of humanity for the way people are showing up for each other in community,” she continued, “and Americans coming out to support each other and protect each other and fight against injustice.”

I just passed a USPS truck with Bad Bunny blasting at full power, and now I'm wondering why there are delivery trucks that aren't blasting music.

“Having neither and bringing the adage into the 21st century, she pounds X (f/k/a Twitter).”

Another solar spill, necessitating overnight emergency drilling in subzero temperatures 🤷‍♂️ (Yes, rather happy our building is off gas completely.)

Let’s be clear- the cost here is dead kids.

Detroit is toast

File under: "What could possibly go wrong?" Even for scientists producing peer-reviewed papers, it's basically all about, "How long can I use AI to BS my way to more publications, until someone finds out I'm not actually contributing anything novel?" Sigh.

One thing snow in Manhattan makes painfully clear: How much public space is occupied by cars dumped there for free long-term storage. #TheHighCostOfFreeParking

34,000 signing up for this work AFTER seeing their fellow citizens gunned down by federal thugs in cold blood? I'm chugging whatever the opposite of doomerism is

Smartest man in the game and he's telling you the press are cowards. Telling you someday everyone is gonna find out

I talk about this a bit in the piece. Large chunks of US institutions were ready to go along with this, including the Supreme Court and a de facto state media that came from the private sector.

I suppose the one big question here is how to account for the decades-long process of building up an alternate reality — talk radio, cable news, "think" tanks, etc.

Despite everything, energy transition investment grew in 2025. I spoke with @gwagner.com and @femkenijsse.bsky.social about the findings, which come from a BloombergNEF annual report: insideclimatenews.org/news/2901202... #energysky

I s'pose that's one way to cut nuclear costs: "Trump administration secretly loosens nuclear safety rules" www.npr.org/2026/01/28/n...

On NPR on Friday, there was a story of a 4-year-old--an American citizen--who hasn't left her house since early December, not even to play in the yard. And her 8-year-old brother recently stopped going to school, too. Their father is undocumented, and the family doesn't want to risk him being taken.

Genuine fascination with the effort that is NYC snow preparedness, check. A call for everyone to chip in for the public good, ✅ Fun along the way, ✅ 💚

While one of the bigger storms blankets the U.S., leading to power outages for millions... Republicans move to dismantle one of the most important climate & weather prediction agencies.

"Videos Contradict Federal Accounts of Fatal Shooting" @nytimes.com just dropped the "appear to" in front of the "contradict[s]." Anyone who knows anything about NYT headline writing knows how big a deal that is.

You have to read this. Firsthand affidavit from one of the women who was there and recording the video. She talks about how Alex Pretti was directing traffic when she arrived. She watched him be killed in front of her. She's afraid to go home, worried she'll be arrested.

Alex Pretti "used to tell people off when they made sexist comments to female physicians. He bought me coffee when I had a really bad day as an intern...I laughed alongside him daily. He made a point to teach medical residents without judgement, but with a smile on his face and a joke."

January 2026: "Trump Razes Old Order, Letting China Fill Void" + a picture of empty US shelves for good measure

Tout n'est pas lié au réchauffement du climat, mais ce lien de cause à effet est très clair. Changement climatique → Températures océaniques plus élevées → Air plus humide → Tempêtes (hivernales) plus intenses

Not everything's always climate change. Not everything's always climate change. Not everything's always climate change. But then... Climate change → Higher ocean temperatures → More moist air → More intense (winter) storms Yes, there's a link csi.climatecentral.org/ocean?lat=26...

2½ days later... Hello world (again)!

But actually, as @gwagner.com reminds us in this article, economists have quantified the mortality cost of emissions. Roughly one death between now and 2100 for every 4,500t of CO2-equivalent put into the atmosphere today. Every tonne matters. 2/- www.project-syndicate.org/commentary/m...

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

"Academy of Fine Arts Vienna extends offer of admissions to Trump: Don't want to be blamed again." Masterful from the German @theonion.com

I just filed an essay on geothermal for @milkeninstitute.org Review, fourth in a mini-series. (The third: gwagner.com/cementing-carbon) Needed a couple references, and I'm told AI is helpful with this sort of thing, so I broke down and tried it. Hm, 2 of 3 are @wikipedia.org...
