Today we presented the European Climate Resilience Framework. Climate change is not a hoax. It is real, and it kills people. Europe has the knowledge, the observation capacities and the data. Resilience starts by turning that information into better decisions and a better response.

Absolutely incredible: Tuesday morning's high tide in #Miami exceeded the major flood threshold... that is the 1st time it has ever happened in the city's history without a hurricane storm surge. It tied (within 0.1 inches) the storm tides produced by Irene on Oct 15, 1999 and Wilma on Oct 24, 2005.

THE ENTIRETY of the rise in inflation in eurozone countries in the first half of this year is due to energy prices Chaining our societies to oil and gas is ruining ordinary people financially – just as it ruins our air, water and safe climate It's time to get Europe off oil and gas

1/3 This summer was the “Summer of Truth”. Wildfires, heatwaves and droughts caused immense human suffering and resulted in high economic costs. That is why today we present the Framework for Climate Resilience. What are we doing concretely? 🧵

This is the kind of study I wanted to see. Several thousand people were offered fixed prices for micromobility trips (no per-minute fees). I would've expected riders to go slower, but apparently not: "No clear effects on trip travel speed were identified." findingspress.org/article/1721...

I watched the box-office flop Digger last night and loved it. I was reminded that unless you’re rich/ powerful, our future will be satire about the new “norm” of climate disasters to laugh at so we don’t cry. And Australia is great source material with all the fossil fuel projects we approve.

It’s funny when they accidentally tell the truth.

I'm going to try to do this cleanly. Today's right wing governments are networked to each other. Those networks are well-documented. You can read about them in books. Following the elections in one node of that network is good practice for understanding the U.S. node.

Recent work suggests scope for more road pricing interventions. In a forthcoming article (2nd screenshot), Jonathan Levine and I argue that before widening highways, DOTs should be required to conduct an evaluation of the costs and benefits of road pricing instead. www.nber.org/papers/w35887

Rivian's CEO predicts that the self-driving future revolves around personally owned cars— not robotaxis. Indeed, surveys show that's what most ppl want. But it would be a disaster for cities/climate b/c personally owned AVs would massively expand car use and sprawl. techcrunch.com/2026/10/19/r...

Fascinating story.

🔄 We need system change. But how can we help change the system?🔥 Global emissions are still not declining, and current climate policies fall far short of the Paris Agreement. We clearly need profound changes to our political, economic, and social systems. 🧵👇

I'm SO excited about this. Our streets should be seen as public spaces, not just territory filled by and controlled by cars. I love the idea of Oxford street being a human-centred space, designed around pedestrians. It'll take a while to develop but 🎉🎉🎉 www.theguardian.com/cities/2026/...

"Among the 16 tipping point systems, the AMOC is probably to be considered the poster child of security risk. It is potentially very close to weakening and shutting down and it would have these cascading impacts across the entire planet." - Johan Rockström www.youtube.com/watch?v=Y0fo...

Good news that constructive EU-China dialogue on climate and biodiversity can take place, despite difficult discussions also are going on regarding trade. 👏 @teresaribera.ec.europa.eu 👏https://www.chinadaily.com.cn/a/202610/23/WS6adab6b7e4b06d4aa0564572.html

Congratulations to my friend Lula on his electoral victory. Democracy and multilateralism have won in Brazil. Europe’s partnership with Brazil is thriving. We will remain by your side for the years to come.

Brazil's electoral court said President Luiz Inacio Lula da Silva won an unprecedented fourth term in the October 25 runoff. reut.rs/4sqU0SS

Lula’s win is the first good news for the planet in a while! I bet it shaves a tenth of a degree off how hot our earth eventually gets, which will save millions of lives Thank you Brazil!

Thank you, ladies.

So good 🎉 I’m so really looking forward to my next trip there (once the new railway line from Budapest opens)

I agree with @rmtransit.bsky.social: Robotaxis strengthen the case for congestion pricing (which was already compelling). His post about Waymo's newly announced launch in Toronto: www.thetransitbrief.net/p/waymo-is-c...

I have a long piece out now in @currentaffairs.bsky.social, where I argue that — even if they call for clean-energy development — insofar they also seek the expansion of fossil fuels, liberals are allied with the petro-authoritarian right. 1/4 www.currentaffairs.org/news/liberal...

“… and we have Greenland” 🤔

Last month observed the largest relative warming signal in the Arctic, which is not surprising for this time of year as the sea ice reforms. The tropical (El Niño) signal is really remarkable though. [Plot shows zonal-mean temperature anomalies, where latitude = y-axis (not scaled by distance).]

"bans cars in bid to revive its fortunes" 👏

🌊 Atlantic current may bounce back In a climate model, the Atlantic overturning current weakened steadily as temperatures rose and recovered quickly when they fell. The Greenland ice sheet kept shrinking regardless. 🔗 doi.org/10.1126/sciadv.aee5373 #AMOC #ClimateScience #Greenland 🧪

I had not really thought of it this way until a friend prompted me earlier this week, but I am basically analysing railways with a Brexit diagram in my head Connecting my previous and current work in a quick blog post 👇 jonworth.eu/analysing-rail…

Two bridges in Denmark. One from 1887, now mainly for cyclists. One from 1998, where cyclists aren’t allowed. Which one moves most people?

According to a Swedish expert in the automotive industry, car dealers no longer wish to keep cars with internal combustion engines in stock for fear of accelerated depreciation

“When feeling tryg, attention widens. The world can be met with a quiet, open curiosity” And with trust. Which is good in itself, but also highly effective in fostering collaboration to the benefit of innovation, business, regulation and democracy And yes, for sure, not all is perfect. But much is
