"In March, the U.N. considered a resolution to establish an International Day of Hope and an International Day of Peaceful Coexistence. On both propositions, the United States voted 'no'".

Power is the rock on which truth founders. The mainstream media, with a few exceptions, is a single-issue lobby group, whose purpose is to assert the rights of capital. Here's what I've learnt about the industry in 40 years in journalism. www.theguardian.com/commentisfre...

Last week I was at the BPS Social Psych Conference @bps-social-psych.bsky.social in Oxford @ox.ac.uk The theme was Beyond Tribalism—bringing different traditions together organised by @shelleymckeown.bsky.social @swedishprotests.bsky.social @nascherme.bsky.social Some reflections in a thread 👇

🔥Growing the climate movement by centering transformative adaptation In a new preprint, Kevin Young, @swaziadam.bsky.social, & I advocate for transformative adaptation as a framework to better connect people's material interests with climate change and increase mobilization. osf.io/preprints/so...

Ever stared at a table of regression coefficients & wondered what you're doing with your life? Very excited to share this gentle introduction to another way of making sense of statistical models (w @vincentab.bsky.social) Preprint: doi.org/10.31234/osf...

Social movements play an essential role pushing for action on climate and nature, and it’s now widely recognised that support from scientists can make them more effective But not everyone can take to the streets or risk arrest That’s ok – there’s lots we can do in other ways 🧵1/

Motherfucking wind farms…

Everything we've made will break, buildings and streets will crumble, and cities will be abandoned. But the CO₂ we emit into the atmosphere will persist for centuries, and the climatic impacts will last longer than human civilization has existed. This is our legacy for the future.

Are climate activists portrayed as polarising & violent in the news media? Are risks & solutions to climate change mentioned? We used ChatGPT to answer these questions based on > 4,200 articles from seven major German newspapers: link.springer.com/article/10.1... w @jmbh.bsky.social & Simon Wimmer

In our now published letter in @pnas.org, we raise two wider issues for behavioral science: 1) Intentions are poor predictors of behavior 2) Effects on intentions need not generalize to effects on behavior We join calls for researchers to measure actual behavior: www.pnas.org/doi/10.1073/...

I greatly enjoyed our workshop on climate action, which brought together experienced organizers & engaged scholars for a week of reflection & discussion. Outputs coming fall. We need more of these spaces! Organized w @swaziadam.bsky.social Dipti @berglundoscar.bsky.social @jksteinberger.bsky.social

This 83-year-old priest has just been arrested for holding a sign which read: “I oppose genocide. I support Palestine Action.” According to Starmer’s new law, this puts her in the same category as an ISIS or Al-Qaeda terrorist, with a prison sentence of up to 14 years.

🚨 How do exposure to extreme weather events and the subjective attribution of these events to climate change relate to climate policy support across the world? 🔥🌎 Find out more in our OA article published in Nature Climate Change 👇 1/7 🧵 www.nature.com/articles/s41...

🔥 Climate impacts & perception I significantly updated my preprint, which using representative survey data from 142 countries (N=128,093) shows that climate hazard experience is related to higher climate risk perception. Now includes an exploration of country heterogeneity: osf.io/preprints/ps...

Haha, PsyArXiv confusingly has a "create a new version" button, which is not what you want — it creates a new version (with a new URL) rather than updating the old preprint. To update the old one, one needs to use the "edit preprint" button. So now I have two versions. Thanks Obama!

“Donald Trump has guaranteed that Iran will be a nuclear weapons state in 5 to 10 years from now.” Iranian writer @tparsi.bsky.social tells @mehdirhasan.bsky.social that US bombing of Iran would push Tehran toward developing nuclear weapons. Watch the full conversation: zeteo.com/p/breaking-t...

The Masters Expo claims to unite "the top of the Netherlands" in a "community of greatness." But what kind of greatness is built on inequality, oligarchy, & pollution? In @parool.nl, @maiensachis.bsky.social & I argue: to build thriving societies, we must limit extreme wealth. tinyurl.com/4s3b8sby

Systemic protections and guardrails are essential to a functioning society. Nature understands this even if oligarchs don't.

I really enjoyed speaking with a group of highly engaged students last week about the climate crisis, the failures of current climate policy, and how collective action can help secure a livable future. 📑 Slides: tinyurl.com/s6bkjrbv 🎥 Recording of a similar talk from 2023: tinyurl.com/yay564ks

🚨 Expressing intentions is not climate action 🚨 In behavioral science & environmental psychology, we often measure intentions — people saying they intend to drive less, eat plant-based, or join a protest — rather than actual behavior. There are two big problems with this: osf.io/preprints/ps... 🧵

I sent the following letter to The Guardian in response to this piece by Mahmoud Khalil: www.theguardian.com/commentisfre.... They didn't end up publishing it, but I thought I would share it here anyway.

What a show on the last day of ACSCC 2025 where our brilliant participants presented the culmination of their week-long collaborations. Buckle up for today’s highlights👇

The BBC is institutionally biased towards the right and the far right, and here's the proof: the results of an almost perfect before-and-after experiment. My column today. www.theguardian.com/commentisfre...

Time flies and we are already halfway through ACSCC! Today was kicked-off by @doynefarmer.bsky.social, who gave us a deep dive into forecasting technological progress. Doyne also shared his vision of complexity economics for a better world, and showcased his impressive modelling work at Macrocosm.

The second day of ACSCC was again full of inspiring lectures and discussions! Day two was kicked-off by the keynote of Tim Lenton, who gave an introduction to tipping points and an update on the latest research, followed by a discussion about effective leverage points using positive tipping points.

The second edition of ACSCC is officially underway! We had a fantastic first day, welcoming over 40 participants from a wide range of disciplines — including economists, lawyers, social scientists, metallurgists, and more. Once again, we are blessed with wonderful sunny weather here in Amsterdam! ☀️

A massive study of 50,000 households over 1,000 archaeological sites provides ample evidence that inequality is not a "natural" outgrowth of sophistication. Instead, it is a political choice. Which means, kids, that we don't have to choose it. archaeologymag.com/2025/04/stud...

I'm very excited about the speaker lineup for @acscc.bsky.social, which kicks off next week! The following talks can also be followed online: Tim Lenton: tinyurl.com/5d9ubts9 Joyeeta Gupta: tinyurl.com/kbk92rap Doyne Farmer: tinyurl.com/vdrhjvwe Vítor Vasconcelos: tinyurl.com/4v8jawt8

This is a vital intervention by @arstechnica.com. We must fight. Fight not just to protect universities as places of learning for all. Fight not just to save our own jobs. But fight for the guiding role of knowledge and reason itself. Let us not go gently into that dark night. tinyurl.com/33v3bvc5
