A geologist and a systems engineer walk in to a bar... ...and start arguing about whether we can actually pump enough CO2 underground to hit net zero. That's more or less how this paper got started with @hdaigle.bsky.social. Read on to find more: iopscience.iop.org/article/10.1...

Dancing very very VERY close to saying “OpenAI stole our almost-complete proof of Navier-Stokes from internal access to our ChatGPT sessions because they were desperate to scoop Anthropic” which is absolutely 100% a believable thing OpenAI would do right now cims.nyu.edu/~tristanb/st...

the necessary step 1 of rebuilding trust with our allies is prosecuting almost everyone in the trump administration for the countless crimes they have committed against the country and the world

This is really top-notch work. Accessible, timely, and sobering.

Wow, these sequestration rates (even in medium scenario) are not just unrealistic, they are fantastical. Our work on geological limits to carbon sequestration shows that even achieving 1 Gt/y will be challenging without significant tech breakthrough. Relying on CCS today is not a realistic plan!

Discovery & exploitation of US shale gas is one of the biggest stories of energy sufficiency in the world with significant economic benefits. However, creating jobs is not one of them. US shale is increasingly automated & efficient. Same with datacenters - permanent job creation will be minimal.

"Only 2% of the ships that transited through the strait over the last month were hit" The "only" is hilarious. I'm sure maritime insurers love the thought of every 50th ship exploding into a fireball

23% drop in student visas to US in 2025 57% drop from India alone catastrophic for research and learning, here and abroad www.insidehighered.com/news/global/...

You wouldn’t believe the AI compliance training I had to do today! OK, you probably would. “Everyone is adopting AI, how can we protect ourselves?” Garrett’s piece is a good counterpoint- this isn’t inevitable, and the tide is actually starting to ebb…

Not in the paper, but I'll add this anecdote. A friend who used to work for an operator that did a lot of carbon storage told me that their biggest expense was remediating old wells that could be leaky. So I'm skeptical that we can use existing boreholes or even entire assets for this.

This chart shows # of wells needed at various CO2 injection rates to achieve CCS targets (diagonal lines). At typical rates (0.2-0.4 Mt/y), we need 1000s of wells/yr to reach 1-3 Gt/yr rates. (For comparison: # active drilling rigs in June 2026: 581). iopscience.iop.org/article/10.1...

This is a key chart for the future of oil demand. Detroit may force policy makers to keep US isolated as the world rapidly moves on to better and cheaper technology. US taxpayers are the ones left holding the bag, paying more for inefficient vehicles. t.co/Ly9V20Vi1p

Jon Ossoff tells Lawrence O’Donnell: “It’s been amazing to watch this White House melt down over this all week. And about Natalie Harp, these White House staffers are adults — public officials, paid by the taxpayer, with immense power in positions of public trust… No one cares about their feelings.”

Advocates often point to EOR to say that we have been sequestering CO2 successfully for decades. However, they fail to note that average injection rate for EOR projects is only 0.0045 Mt/y and done intermittently, far lower than rates required for point source CO2 sequestration.

Not only did they absolutely beg for this, they made it so that “merit” was synonymous with being white so now you’re stuck with precisely the kind of moron who believes that. www.politico.com/news/magazin...

The complete elimination of Meta would yield unambiguous, far reaching benefits for global society.

A new court filing suggests that Border Patrol lied about the basis of a traffic stop that led to the shooting of a US citizen, a German tourist, and a Border Patrol agent. Only when cases go to court do we find out about DHS lies and its unlawful tactics come to light.

funny how the cutting edge of the far right is just regurgitated slaveholder agitprop from 1850.

Administration officials must be criminally prosecuted for violating US law. Even basic human decency would make you think twice about doing this, but that's too much to ask for this goon squad.

The media (I mean NYT, NPR, and WaPo, not Fox) have most of the blame. The people who report on this stuff do an absolutely horrible job.

This @juddlegum.bsky.social / @atrupar.com piece on how CNN & CNBC commentators regularly cite Kalshi odds, as if they're truly predictive of markets, is very much worth your time. And seeing people like Enten and Sorkin playing along is really disturbing. popular.info/p/how-kalshi... 1/

Abolishing ICE should be the moderate position for any 2028 candidate. Every ICE employee and officer should be investigated for criminal conduct. Their actions are lawless anti-American and must not be allowed to continue.

If there’s an issue Democrats could run on and win in a landslide, it’s anti-corruption. But first the Dem establishment needs to deal with its own corruption problem. It’s not enough to be right about Trump’s corruption—they also have to be credible.

The end goal of the conservative project in the US - aided by Republican lawmakers and the far right ecosystem - is to enact something like this here. They literally want to make America more like China, and we need to oppose at the ballot box and everywhere else.

Can everyone just step back and realize how insane it is that the US Supreme Court had to rule on the constitutionality of the US CONSTITUTION and the vote to uphold the Constitution wasn't unanimous!!!

It is a fool’s quest to try and appease anti-immigration advocates. Their goal is to destroy everything that’s good about a multi-racial and multi-cultural society and make the US a Christian nationalist state. Any concession - like repealing TPS - is simply a step towards ethnic cleaning.

They want to convince their followers that we are un-American, in the wrong country. But it’s them. THEY are in the wrong country. Their goals, plans, ideology are no less than an insurrection against the Second Founding - the constitutional framework for our country created after the Civil War.

Also a Big Yikes for reactionary centrist pundits (yes, that one in particular, but also others) with the bad habit of treating poll numbers as some sort of immutable assessment of values rather than messy metrics of temporary and easily moved attitudes of a generally mid-to-low info electorate.

if you have feelings about SCOTUS after today, and after the last week, and after the last months and years, remember that at least you can vote for state supreme courts in many places this year, and those matter a ton too my state-by-state guide to every state supreme court contest:

The real headline from the birthright‑citizenship case isn’t the outcome. It’s that four Supreme Court justices signaled they believe a president can effectively rewrite the Constitution through executive order.

court packing is the moderate position. constitutional redesign is the only way, and we need to get serious about it.

5–4 on a constitutional question that is older, more settled, and just as clear on the text and purpose as "can women vote?" They're coming for that one too, it's currently in the "right-wing extremists on social media" stage, same place where "there's no birthright citizenship" arose.

"US One Supreme Court Vote Away From Stripping Basic Constitutional Rights" should be the headline for every news outlet in the country.

With this ruling, the birthright issue is not going away. The right hasn't really begun *organizing* around getting rid of the citizenship clause. Like Roe, this will be their fight for a generation. And if the Democrats just say "we won" and ignore it, like Roe, the Republicans will eventually win.

Oh my god, I thought the aversion to AC in France is some inside joke about technology or bureaucracy but they actually hate AC? How is France's national psyche one of austerity? We need more electricity, we need more low-carbon electricity, and we need everyone to have AC and heat.

Is it just me or are these good comments? The email starts by clearly stating that these are suggestions. More often than not, this is the kind of feedback we want from readers, collaborators, and funders. Too often, we don't because folks are busy. But this type of critical feedback is *useful*.

I am more bullish about CCS than many of my peers but this is a stunning chart about our inability to predict how technologies can evolve. At this point, I think it's up to the proponents of CCS to prove that the technology can scale up. projects.propublica.org/why-carbon-c...

"I have enough money to do research," says Shu, laughing. Meanwhile HHS shut off the NIH grant that funded related work on gene therapy for deafness at Harvard Medical School, because “woke” or something like that Shu trained in the very same lab that HHS defunded

Two researchers — one in Massachusetts and one in Shanghai — hoped for the same breakthrough: a gene therapy for deaf children. New Chinese investment in science propelled the one who got there first. n.pr/4weVi49
