This is going to be a big deal, but easy to get the wrong end of the stick on it. So I think it's worth breaking down what actually happened, why, and what it actually means, based on the public information reported here, because it's a bit complicated for folks who don't follow this stuff closely 🧵

Out in Climatic Change: I show that major emitters defecting from their Paris obligations lowers citizens' support for ratcheting up climate policy - especially when citizens fear economic Green Transition costs. Likely, Trump's withdrawal matters beyond the US. link.springer.com/article/10.1...

Happy Schuman Day! ✌️🇪🇺🔥

The Council and European Parliament have agreed on the AI Omnibus last night. That negotiations concluded so quickly shows the immense political pressure to act, but it remains questionable whether the AI Omnibus can really fulfil the expectations of fostering growth and innovation pinned on it 1/

UPDATE 🇨🇭🇪🇺: After the Swiss federal govt adopted the Switzerland–EU package in April 2026, parliament is now deciding which majority rules will apply in the likely 2028 referendum. Today, after a 6:6 tie, the committee chair cast the deciding vote in favor of a supermajority requirement #Ständemehr

Delighted to share a short blog post on the dark logic of visual "strongman" propaganda — drawing on survey experiments in Venezuela, Türkiye and the US!

Public support has often been treated as a backdrop to global governance. But in a review article with @the-peio.bsky.social, @jonastallberg.bsky.social and I argue that what the public thinks matters for how (well) international organisations operate: link.springer.com/article/10.1... #poliscisky

Many middle powers are fast diversifying trade ties away from the US • In May-Dec 2025 trade among UK, Canada, EU, Japan, South Korea and Switzerland rose by 12% • EU leads the way, as recent burst of free-trade deals with Mercosur, India and Australia illustrates www.economist.com/finance-and-...

This is quite extraordinary- scientists set a kind of trap for AI chat bots by inventing a fake disease. AI told people it was real and… the deliberately bogus preprints started being cited in peer reviewed literature 🫣 🧪 #MedSky www.nature.com/articles/d41...

Anymore views on this? Thanks to everyone engaging 🙏

Always good to see scientists replicating previous famous findings.

MAGA's war on European civil society is escalating. Visa bans for NGO leaders and former EU officials, plus congressional demands for documents - it's all about undermining the Digital Services Act to protect Big Tech. If Europe doesn't push back hard, "the law is dead." www.ftm.eu/articles/tru...

Carney to Europeans + other middle powers: “When we only negotiate bilaterally with a hegemon, we negotiate from weakness. We accept what’s offered. We compete with each other to be the most accommodating. This is not sovereignty. It’s the performance of sovereignty while accepting subordination.”

This is dangerous for many reasons, not least the information suppression that this causes. Lots of pressure on the EU to continue defending the torch of cooperation and, frankly, collecting data for the world now

Another day, same story in the European Parliament - talks between the centrists parties collapse, and the centre-right to far-right forms the majority, today expectedly on the deforestation regulation. At least on the simplification/deregulation agenda, it now seems to be the de facto EP majority:

"Support for prevention has the hallmarks of “real” attitudes: consistency across wordings and response formats, including open-ended probes; steadfastness in the face of arguments; and willingness to make trade-offs against disaster relief, increased taxes, and reduced spending on other programs."

"Brussels’ focus on market influence has become a dangerous blind spot. For instance, officials may treat digital protections as bargaining chips rather than a crucial bulwark of European democracy or a defence against foreign influence. That would be a terrible mistake." 👌

Keep thinking about the long established right-wing voting coalitions, too. But now ALDE/Renew is replaced by Patriots, so there is a qualitative differences. Another difference is that in years past there where options of centre-left majorities and ALDE was the pivotal group.

Great primer on today's breakdown of the cordon sanitaire in the EP including the prehistory of the vote and its implications.

Residential mobility also matters: Urbanites who grew up in rural areas but later moved to cities are less polarised. Divided loyalties dampen affective divides — helping explain why ruralites are consistently more polarised than urbanites. 5/7
