"Scientists must distinguish between empirical judgements about evidence and political judgements that are rooted in values." Yes. Also politicians should equally clearly distinguish between their judgements about the science and values trade-offs. This is hard. www.nature.com/articles/d41...

Scientists should recognize their own political biases to build public trust

Public trust in science can’t be sustained by the support of narrow constituencies at one end of an ideological spectrum.

NEW: Is there a 'crisis' of public trust in science? It can feel that way — with attacks on research in the US and growing rejection of vaccines. I investigated for @nature.com - and found some surprises. My feature article is out today and a short🧵here www.nature.com/articles/d41...

Have people stopped trusting science? The data tell a surprising story

Some say there’s a global crisis of trust — but research reveals where the real problems lie.

"Interventions should therefore aim to support productive conflict and civil disagreement in a pluralistic space — one that can yield greater mutual understanding, improved democratic deliberation, and more equitable collective decisions." Amen.

New Nature paper with the brilliant @yarakyrychenko.bsky.social! Digital technologies are shaping the public sphere but were not designed as democratic infrastructure. We propose aligning social technologies with democratic principles of inclusivity, fairness, & representativeness. rdcu.be/fqnyw

If not scientific evidence, what other information weighs heavily with policymakers? Was Keynes right that "Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist."? #1

To what extent is the failure to address the climate crisis a driver in a loss of trust in democracy and democratic institutions? Are other major unsolved societal challenges driving disillusion and distrust more?

Important argument for science & democracy in recent encyclical. “The search for truth is an essential element of democracy … When questions about what is true lose their appeal, and a pragmatism takes hold that is content with what appears useful or effective, then democratic life is weakened …”

tl,dr; Scientists no longer allowed to use federal funding to publish, attend meetings, or talk to the public. They cannot collaborate internationally. Grants can be cancelled for any reason, at any time, political appointees have a final say over what gets funded, and who gets funded.

The White House today announced it plans to make major changes in how the U.S. government manages research funding. https://scim.ag/43HgW4s

32.3ºC at Kew Gardens is the hottest May temperature on record at the station since records began in 1881, beating its previous May maximum by 2ºC (30.3ºC, 25th May 1922). It beat its maximum temperature date record for the 24th of May by OVER 2ºC (30.2ºC, 1922), exceptional.

Spaghetti chart showing Kew and Kew Gardens May daily maximum temperatures from 1881 to 2026. 144 years of May temperatures are shown as thin grey lines, forming a band broadly between 10°C and 30°C throughout the month. The 2026 line is highlighted in bold red and rises sharply to 32.3°C on 24 May. Two dashed reference lines mark the previous May record of 30.3°C set on 25 May 1922, and the previous 24 May date record of 30.2°C also set in 1922. The 2026 value exceeds both by more than 2°C.
