1. We—@eduede.bsky.social, @mjcrockett.bsky.social, Kevin Gross, and I—have a new preprint on the arXiv today, based on ideas that emerged during an @sfiscience.bsky.social workshop in November 2024: The unintended consequences of large language models as a labor-augmenting technology in science.

The unintended consequences of large language models as a labor-augmenting technology in science

As a labor-augmenting technology, large language models (LLMs) have the potential to accelerate scientific activity across the research pipeline. But even if LLMs perform on par with human experts at ...

It was inevitable, wasn't it🙄 Of course the Telegraph would run with something like this👇 So let's remove some of the rose-tinted spectacles and also look at some of that data comparing 1976 with modern heat waves Because the 1976 nostalgia porn is wearing a bit thin at this stage 🧵1/23

🚨 New research by us! 📣 Most British drivers don't know how dangerous SUVs are to other road users, but adding information to SUV marketing materials seems to do almost nothing to change people's plans to buy SUVs Here's a 🧵 on why harder action is going to be needed 1/10

"We didn't become biodiversity scientists to preside over decay." — Becky Chaplin-Kramer Eight times more papers document biodiversity loss than recovery. We're better at describing what's broken than understanding how to fix it. That needs to change. More here 👇

We're great at documenting decline and surprisingly bad at understanding recovery

It remains very weird to me that in a world of actually useful technology -- photovoltaic power generation, mRNA vaccines, maglev trains, smart phones, etc -- the tech sector has gone so all-in on bullshit generators and plagiarism machines.

🚨NEW: The impact of climate change on our economic stability is being hugely underestimated. Our latest analysis shows climate damage could drive the EU’s debt-to-GDP ratio 58 percentage points higher than official projections by 2050.

Text: If Europe stays on its current trajectory climate damages will drive debt-to-gdp ratios over 100% high than official projections in the worst hit eu countries. With a heat map showing the increase in debt-to-gdp ratios in different EU countries.

Lastly, the anti-science movement has an extremely easy time because of the cowardice of institutions. They leave their scientists out to dry. You cannot ask individuals to defend science and reality while denying them collective backing when the predictable harassment arrives at their feet. 13/

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right. Moving from chronological feed to the algorithmic feed also increases engagement. This is one of the most concerning papers I’ve read in awhile.

The political effects of X's feed algorithm https://doi.org/10.1038/s41586-026-10098-2 Received: 16 December 2024 Accepted: 4 January 2026 Published online: 18 February 2026 Open access • Check for updates Germain Gauthier,5, Roland Hodler?5, Philine Widmer35 & Ekaterina Zhuravskaya3,4,5 m Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

Excellent thread on the side effects of efficiency. So often is efficiency touted as a solution to solve resource issues, without explicitly mentioning the main intent, which more often than not is more growth.

Dr. Aaron Thierry@thierryaaron.bsky.social · 6mo ago

Efficiency, optimization, productivity: celebrated as universal goods. These ideas are especially influential in economics, engineering, and computer science. But what if they reshape our systems and lives in ways we rarely notice? 🧵

You may’ve seen coverage of a new report on the threat to national security from environmental collapse. A common response that’s got my goat is: “Look, it’s not just tree-hugging enviros saying this, it’s hard-nosed spooks!” A short thread on why this framing is bad history & bad politics🧵😡😉

10/ Politicians igored them because warnings alone do not compel action in the face of organised vested interests. Fossil capital. Extractive industries. Short-term political incentives. Institutional inertia. These were always the real obstacles, not a lack of credibility.

The heat energy we added to the ocean LAST YEAR is the equivalent of: - Detonating ten hydrogen bombs every minute - operating over a hundred large power plants continuously for all of written human history - Five times all the electricity human beings have ever used

Zeke Hausfather@zekehausfather.com · 7mo ago

Ocean heat content increased by 23 billion trillion joules, which was around 39 times greater than global primary energy use this year. This is the largest rise in OHC since 2017; overall OHC has increased by over 500 zettajoules since the 1940s.

"Efter mer än ett decennium i den här branschen är det uppenbart att bara min blotta existens i samtal alltid har väckt starka känslor. Manliga motdebattörer är inte så här oförskämda mot vita män." @somar.bsky.social om den famösa debatten i söndagens "Godmorgon världen".

Högermännen blev rasande när jag pratade om rasism i radio

Jag sa att regeringen inte finns till för hela Sverige. Cwejman och Wikström blev så vansinnigt arga att de började avbryta i det gemytliga programmet.
