With "efficiency" people think about the engine thrust per amount of fuel. But airlines have an operational efficiency also depending on load factors, cabin layout (first class booh!) and aircrafts being used. We measure this in gCO2 emitted per revenue passenger kilometer. Some areas

Yay! We got an exclusive feature from The Guardian on our paper, published today in Nature Comm Earth&Environment www.nature.com/articles/s43... Airlines won't like it but we suggest to get rid of business and first class. Why? Because that way more people can fly for the same emissions

How big is too big for a pull request? 😬

I think on an iPhone it’s impossible to stop for exactly 0.37s. 0.36 yes, 0.38 too but not 0.37. Why?

Also will be renamed to ClosedAI to better reflect the company's values.

Farage: epic grifter

Woa? Crazy to see how well they are correlated. Anyone an explanation for that?

Anyone knows how much of that can be attributed to the change to GPUs? 5 years ago some supercomputers had GPUs but not all, now it’s hard to find the CPU-only ones!

How much more efficient have supercomputers become over the last 5 years? Just analysed the top 100 of top500.org : 4x for the most efficient supercomputers in the world, what was top in 2020 is now at the bottom of that Green100 list. Total energy consumption has increased nevertheless

I didn't know the world largest offshore wind farm Dogger Bank is being built off the coast of Yorkshire, 4GW!!! It's huge, so cool

Millions of liters of sewage by Thames Water and co is fine but a bit of COFFEE that's illegal 😂 www.theguardian.com/uk-news/2025...

Just a funny little 1D shallow water model using Julia, Makie, and Pluto!

Big oil has always been lying to us.

Want to look at variables from a climate model simulation interactively? SpeedyWeather got you covered

Big fan of Pluto notebooks @fonsvanderplas.bsky.social for SpeedyWeather github.com/SpeedyWeathe...

GeoMakie & GLMakie usage in SpeedyWeather. Interactive climate modelling yay! Here just visualising the HEALPix grid

Amazon is a pile of shit. Turns out, enshittification has not reached BlueSky yet www.theguardian.com/technology/2...

You think ripples in spectral models are weird? Yes, step functions in spectral models are represented with many "weird" oscillations. Sea level will be negative next to big mountains, etc. But that's just the equivalent of representing something smooth with little discrete steps, which arguably 🧵

Bikes, also effective against ICE.

Sorry Brits, stupid question: What’s baked about baked beans?!

Is it professionally acceptable to not have MS Word/Powerpoint/Excel etc and ask for other formats? Maybe just me but I find this software exceptionally fragile: A powerpoint presentation created with powerpoint cannot be opened with powerpoint with a hint to open it with powerpoint, wut???

Closed my spotify account as other music streaming services like Deezer pay 2x more to artists and don't invest into AI weapons like the Spotify CEO does. Consumer choices are important!

Hahaha. I would not have expected to give better live demos than Mark Zuckerberg 🤣

Name it Kentwich University, what a missed opportunity for a sandwich www.theguardian.com/education/20...

First attempt at writing a sea ice model 🧊🌊 Only uses sea ice concentration not thickness so there is not enough "memory" of thick ice to retain some sea ice cover during summer. Not bad for zero tuning though, I find! Will be in the next release of SpeedyWeather github.com/SpeedyWeathe...

Car drivers criticise cyclists for jumping red lights. If it’s busy or in any way potentially dangerous I 100% agree. But in other situations I also understand cyclists thinking: I don’t kill people, cars do, most road infrastructure (🚦🔄🛑⛔️…) is built to safe people and cars from cars (🤯) so I can go

Everytime I cycle through a traffic jam and feel that some cars might be annoyed by me squeezing through, I think: It’s not my traffic jam, is it?

Anyone thinking these days how the civil war in the film Civil War actually unfolded? What if Californian law enforcement started to restrict federal forces somehow?

Senior professors affiliated with NOAA had to withdraw their presentations at EGU in Vienna because they wanted to talk about climate. And travel on personal means. This is what fascisms looks like.

Good morning Vienna! Everyone at EGU? Interested in the Julia programming language? Join our short course today at 2pm! meetingorganizer.copernicus.org/EGU25/sessio...

I'll be at @egu.eu 2025 next week in Vienna. You can catch me on Monday at 14:05 in Room 2.92 talking about "ClimateBenchPress: A Benchmark for Compression of Climate Data". I'll be at EGU the whole week so let me know if you want to chat about (neural) compression for climate or anything else!

It was always about market manipulation. I bet Trump tells all the billionaires in advance what tariff plus minus he’s going to announce and they just sell and buy accordingly in exchange for not criticising him.

I have a trade deficit with my grocery store … and I think I like to keep it that way. I’m not going to sell our potatoes to the grocery store.

THE WIND … RUINS THE LANDSCAPES

Holy shit. This is my old neighbourhood. Tuft student gets arrested on the street by masked ICE officers like it’s Nazi Germany.

BREAKING: Denmark offers to buy Long Island from the US in exchange for 10 million eggs. www.theguardian.com/us-news/2025...

Closing the Mauna Loa observatory is like stop counting cases and deaths during a pandemic

Dear American friends and fellows. So what is needed to trigger a movement on the scale of Black Lives Matter? Or is everyone already tired after 50 days?

Why do people think that Die Linke is as radical as AfD? One party wants billionaires to share their wealth whereas the other has a propaganda that holocaust and Russia aren’t actually that bad.

I hope this is funded by all other car companies selling electric vehicles

How a multiparty democracy allows for fascist parties to rise but also controls them better because there are alternatives to the alternative. Trump was the only alternative to Biden.

A SpeedyWeather-curious user on GitHub asked: Can you do Kolmogorov Flow? EASY, ~5 lines of code later

What Google should have said! 👇

Shame on you Google.

Haha. It snows a good amount in Boston and the ice cream shop in Davis Sq is “busier than usual” and sells ice cream till 11pm.

Phd from Oxford? I went through this programme in an earlier version and can now supervise students in this new ILESLA PhD programme! Environmental research includes climate research, modelling and machine learning. You got 2 weeks to apply 😱

The damning statistics that reveal the true cost of Brexit, five years on:
