What better way to end 2025 than getting our paper published in Global Environmental Change 🥳💚 We studied perceptions of the feasibility of climate-relevant behavior change and how these perceptions connect to income differences and climate policy support. Let me tell you all about it🧵👇

On the 10th Anniversary of the Paris Agreement, you’re going to hear a lot about the progress we’ve made — people saying we “are” heading to 2.5 degrees heating instead of four. I deeply regret to tell you that this is complacent misinformation. 🧵

🚨 Mapping climate change coverage In a new preprint, Simon Wimmer, @jmbh.bsky.social, and I analyzed over 50,000 articles about climate change from major German newspapers across the political spectrum (2010-2024) using large language models 🧵 🔗 Link: osf.io/preprints/so...

My latest: with @fdabl.bsky.social and JW Bolderdijk we argue that environmental psychology needs formal theory to make progress and increase real-world impact doi.org/10.1016/j.co... Part of special issue Behavioral Science for Climate Change by @madalina.bsky.social & @neurograce.bsky.social

Scientists are becoming more visible in public climate debates, but the effects of this engagement are far from straightforward. We often hear strong claims about credibility and trust, yet what does the evidence say? Our new preprint explores this osf.io/preprints/ps... Thread 1/n

⚠️ When “technology will save us” becomes a climate risk! A new paper from great colleagues takes a careful look at techno-optimism — the belief that technology will largely solve climate change — and what it means for real-world climate action. (1/4)👇 osf.io/preprints/ps...

I am beyond excited to announce that the applications are now open for the third Amsterdam Complexity School on Climate Change! Come visit a beautiful city, hear from world-renowned experts, and work with passionate individuals on challenges related to climate change. More info: acscc.nl

🚨Techno-optimistic scientists take fewer climate actions In a new preprint, @colognaviktoria.bsky.social, @maiensachis.bsky.social, @jmbh.bsky.social & I examine techno-optimism among 9,199 scientists and how it relates to their civic engagement and lifestyle choices🧵 🔗 Link: tinyurl.com/hh94huzv

Understanding and Accelerating Collective Climate Action Important new report from @fdabl.bsky.social, @jksteinberger.bsky.social, @swaziadam.bsky.social, @berglundoscar.bsky.social and other leading thinkers in the climate movement A must read for all climate activists zenodo.org/records/1758...

🔥We've crossed 7 out of 9 planetary boundaries, & global heating is accelerating. What is to be done? 24 scholars, activists & practitioners met at a 5-day workshop to explore how to accelerate collective climate action.

I've finally got around to curating a selection of films about the #climate crisis 🎥 There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️ They make excellent resources for classrooms, lecture halls, or community cinema's 🎬 Thread:🧵Plz RT

Wanting to be part of change but feeling overworked and disempowered: Researchers’ perceptions of climate action in UK universities Big study published last year which I realised I hadn't shared properly here (was before joining Bluesky). Article ➡️ doi.org/10.1371/jour... Some key findings... /1

Elon Musk's involvement in politics really hurt Tesla sales. "Without the Musk partisan effect, Tesla sales between October 2022 and April 2025 would have been 67-83% higher, equivalent to 1-1.26 million more vehicles."

⭐ After quite some time in the making, I’m excited to share our new paper!🌿⭐ We examined people's climate-relevant behaviors (driving, air travel, public transport use, and meat consumption) and their perceptions of how feasible it would be to change them (+ expected wellbeing impacts). 🧵(1/4)

I was recently invited to present my thoughts on the role of universities in the #climate crisis Several audience members asked that I share my slides, so I've decided to post them here too as an open resource I'd love any feedback, & for you to share examples of projects & best practice. Long 🧵😊

Yes the CO2 rise 2023-2024 was faster than we predicted at Mauna Loa and was a record rise there - now the WMO confirm the global mean rise was also a record Also the rate of CO2 rise is now above the IPCC scenarios that limit global warming to 1.5C www.carbonbrief.org/met-office-a...

Hi all! I’m looking for research jobs in social psychology, environmental action, & climate policy. I study pro-environmental action, moral and identity processes, scientist advocacy, and universities’ climate responses. I use qualitative and quantitative methods for research with real-world impact.

10/ The plenary discussion was wide ranging, a theme that came up repeatedly was the barriers that academics can face when partaking in advocacy & civil society organizations & how these can be overcome. A topic that is explored in detail by @fdabl.bsky.social et al www.nature.com/articles/s41...

It's the 'Scientists Responsibility Summit' today. Here's a live thread with some take aways from each talk... 🧵

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...

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!
