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

⚠️ 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°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.
