Our global study on the state of trust in scientists is now out in Nature Human Behaviour! 🥳

With a team of 241 researchers, we surveyed 71,922 people in 68 countries, providing the largest dataset on trust in scientists post-pandemic 👇🧵https://www.nature.com/articles/s41562-024-02090-5

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 🎬

This! 🔥👇 Couldn't agree more, thank you @kristiansn89.bsky.social
🔥 The never-ending narrative…
This week, I’ve once again heard prominent climate researchers dismiss individual action as either irrelevant or a distraction instigated by the fossil fuel industry.

Here’s a 🧵 on why this argument frustrates me to no end and why I think it misses the bigger picture.

How much do people really reject science?

New paper out doi.org/10.1177/0963...

In four studies, we asked Americans—including flat Earthers, climate change deniers and vaccine skeptics—whether they accepted basic scientific facts.

The result? A surprisingly high level of agreement. 👇

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/...

🌪️Experiencing extreme weathers had no direct effect on climate policies support.

EXPECTING more severe weather events in the future did.

In sum:
Expectation (not experience) predicts climate policy support!

1°C of global warming does NOT mean that heatwaves 'just' get hotter by 1°C.

Over large parts of the UK, global warming means that heatwaves are 3-4°C warmer, with worse consequences for people and ecosystems.

Can scientists trace climate losses back to the emissions from individual fossil fuel companies?

Yes, we can.

The inimitable @ccallahan45.bsky.social and I provide an 'end-to-end' attribution framework that can be applied in many climate accountability contexts:

New study finds that scientists' engagement in climate protests does not erode their credibility. This supports our previous findings on scientists' advocacy. Thank you for this important contribution @fdabl.bsky.social, @maiensachis.bsky.social, and Adam Aron 👏
🎉 Effects of climate protests by scientists paper published!

Our findings suggest that scientists can engage in public protest without compromising their credibility, but that such actions alone may have less impact than one would like to believe: royalsocietypublishing.org/doi/10.1098/...

Atmospheric CO2 has passed 430 parts per million.

The last time atmospheric CO2 was at 430 ppm was during the ancient Pliocene Era, three to five million years ago, and humans didn’t exist.

We asked 3,000+ researchers from 101 countries if global green growth (i.e. sustainable economic growth) is possible. 59% said yes. 👇

Green growth endorsement was linked to beliefs that economic growth is key to human well-being. Thanks to @manuelsuter.bsky.social for leading this study! 👏

When Congress lets POTUS attack science, they're giving up their own regulatory authority & hurting their constituents.

I talked with @danvergano.bsky.social about why it's so important that scientists take action right now; despite the potential risks.
