New study finds that emphasizing collective efficacy (people's ability to catalyze large-scale change) is very effective in catalyzing behavioural change. As you can see from my pinned post, I'm a big fan of simple messages that can mobilize public support for climate action!

What motivates people to engage in climate advocacy? In a new PNAS Nexus megastudy [https://doi.org/10.1093/pnasnexus/pgaf400] led by @dgoldwert.bsky.social we tested 17 theoretical interventions on a large US sample (N=31,324) to increase public, political, and financial climate advocacy. 1/5

Climate Terminology Does Not Matter Across tens of thousands of participants in two large-scale experiments, we found that labeling climate change in different ways had no effect on their stated willingness to act. jayvanbavellab.substack.com/p/climate-te... via @dgoldwert.bsky.social

Now officially out in @pnas.org with @greggsparkman.bsky.social! Almost 90% of Christian religious leaders believe in anthropogenic climate change. American congregants underestimate this consensus. Communicating this has important consequences for norms and beliefs! doi.org/10.1073/pnas...

Another fantastic #SPSP2025 (my 6th year!). Honored to co-chair the Sustainability pre-con with @sgonzalezcoffin.bsky.social and a symposium, "Psychology at the Forefront of Looming Societal Challenges," with @anasabherwal.bsky.social, ft. @steverathje.bsky.social & @JonRoozenbeek as co-presenters

Should we use "Climate Change", "Climate Crisis", "Global Warming" or another term for this environmental disaster? It doesn't seem to matter! @researchdigest.bsky.social just covered one of our papers led by @dgoldwert.bsky.social with @jayvanbavel.bsky.social & @madalina.bsky.social Check it out👇

🚨 New preprint! 🚨 We analysed over one million actions reported in the AWorld app, the UN's official platform for individual action on climate change: osf.io/preprints/ps... This was an exciting collaboration with @kristiansn89.bsky.social, Jan Bauer, Laura Basconi, & @cameronbrick.bsky.social 🧵👇

1️⃣ post here! Despite decades of research, why is positive pro-environmental behavioral spillover so hard to achieve? @greggsparkman.bsky.social and my review highlights that social and institutional drivers are needed to spur rapid positive spillover authors.elsevier.com/a/1kK0t8MqMi...

Very honored to have won the APA Science Poster Competition Grand Prize! Thanks to all who voted, and to the amazing team behind this project @mikeberkwein.bsky.social @kimdoell.bsky.social @jayvanbavel.bsky.social @madalina.bsky.social

From 1.5C to 2C of global warming is an increase by 33.3 percent. Many people assume that the negative impacts of this would also increase by only 33.3 percent. Unfortunately, that is not the case. The increase is non-linear. This is one of the biggest missing pieces in public climate literacy.

New open access article assessing the common ground between liberals and conservatives on why nature is worth preserving. Turns out they share a lot in common! I did this work with Adam Baimel (@abaimel.bsky.social ), Taciano Milfont, and Ara Norenzayan. 1/n journals.sagepub.com/doi/10.1177/...

Just wrapped up an inspiring few days at the Human Behavior and Climate Change Conference in Palo Alto! Huge thanks to @madalina.bsky.social @smconstantino.bsky.social @helenamiton.bsky.social and @nicoleardoin for putting together such a fantastic group of speakers and attendees 🌎

I often have people telling me that if we just change the name that will get people on board. Newsflash: it won't. Better news: here's what will-helping people connect what they know (their heads) to why they care (their hearts) to what they can do (their hands)! ewn.erdc.dren.mil/podcasts/epi...

What's better: climate "change” 🆚 “crisis” 🆚 “emergency”? New work shows that subtle tweaks in language don't make a difference to green action ⬇️ 🔗 bit.ly/4gnhuko Insight with a climate policy steer: focus on something else 🔎 @jayvanbavel.bsky.social @dgoldwert.bsky.social @madalina.bsky.social

In a new interdisciplinary Nature Climate Change Perspective paper, led by me, @lisgilmore and Rachael Shwom, we offer a critical perspective on #climate and social “tipping points.” 🎁: rdcu.be/d2gBC 🧵

Net Zero needs behavior change. For decarbonization, we need to understand how to enable and encourage green choices (fairly). That’s means shifting: how we heat our homes, how we travel, and what we eat and consume. Don’t ask me, check the latest IPCC report ⬇️ 🔗 www.ipcc.ch/report/ar6/w...

I was asked to contribute to The WIRED World 2025, and this is what I said.👇 Thanks to the editors for reaching out! The climate conversation needs a hard reset. www.wired.com/story/fossil...

🌍 Thrilled to share our new preprint and the first part of my thesis! Using machine learning, we analyzed data from 55 countries to uncover key individual and nation-level predictors of climate change beliefs & behaviors. Let's dive in! 🧵 1/12

New paper! Across two large experiments (6,000+ participants globally), we found no evidence that subtle differences in climate change terminology influence willingness to take climate action. www.sciencedirect.com/science/arti...

One week left to apply for the 2024 SPSP Virtual Sustainability Preconference! We will focus on both individual and structural approaches to addressing climate change. Abstracts are due October 18, 2023. Submit here: spsp.wufoo.com/forms/2024-p...

To limit global warming to '1.5°C with no or limited overshoot', the decline in global CO2 emissions relative to 2019 are: * 48% by 2030 * 80% by 2040 * 99% by 2050 It is 2023 & global CO2 emissions are still rising! ipcc.ch/report/sixth...
