The Warming Stripes have been an iconic way to communicate temperature data. On the latest episode of the podcast, we got to speak to their creator, @edhawkins.org. As a fellow data viz nerd, this was a fun one. The latest episode of our podcast: podcasts.apple.com/gb/podcast/p...

What happened on energy and climate in China this year? A summary of the data, mostly drawing on the latest report from Centre for Research on Energy and Clean Air (by @laurimyllyvirta.bsky.social & team). My latest Substack: www.sustainabilitybynumbers.com/p/chinese-em...

As of today, there are more electric cars than diesel cars in Norway.

When people see me working with headphones on, they probably assume I'm listening to calming classical or focus music. In reality, I'm blaring rap and grime.

Just discovered that Spotify does a "Wrapped for Authors" on their audiobook demographics for the year. Fun! In my experience, climate/energy stuff is usually quite male-skewed, but I was pleasantly surprised to see that my book listeners weren't skewed *that* much!

This is a legitimate scientific revolution in meteorology. Also, to be clear, these models are not the AI LLMs that most people are familiar with. They are machine learning algorithms trained on observations (actually reanalysis).

The Nepalese EV transition. In simple terms, brown on this graph is India's share and blue is China's share. The trigger? India effectively halted all imports of petroleum into Nepal in 2015, an "undeclared blockade", which was "masked as constitutional concern". robbieandrew.github.io/carsales/

In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

Good thread from Dave about the new IEA "Current Policies Scenario" making a lot of the headlines. Here is a very quick mock-up I made of what this scenario assumes for solar PV additions through to 2035, with historical context. I'll let you decide whether this seems likely.

RIP Quentin Wilson. A great communicator and advocate for electrified transport. His calm way of calling out misinformation and trying to cross the divide will be sorely missed. A nice tribute video from: @bobbyllew.bsky.social youtu.be/NlTalT3faSM?...

China's new climate targets made it clear that policymakers are still leaving the door open to a rebound in emissions in the next few years, despite a recent falling trend and clean energy growth rates that will keep emissions falling if sustained.

In a new Gallup poll in the US, 12.4% of adults said that they'd taken GLP-1 drugs for weight loss. 15% in women, and 9% in men. I'd have guessed half as much, but I guess I'm a year behind the times. news.gallup.com/poll/696599/...

The ensemble mean of Google DeepMind's experimental machine learning weather model had Hurricane Melissa hitting Jamaica 7 days out. That's very impressive.

One area where AI has a lot of potential is in weather forecasting and climate modelling. Fairly accurate weather forecasting, in particular, is something that many of us now take for granted. From my latest Substack: www.sustainabilitybynumbers.com/p/artificial...

My favourite event of the year 🧵👇

Big China electricity&industial data update🧵for September: ➡️Power generation from coal and gas dropped 5%, for a 1.2% fall in the first nine months of the year. ➡️Crude steel production fell by 5% and cement output by 9% in Sep, accelerating from 3% and 5% drops year-to-date.

On November 4th I'll be in London at the How To Academy, discussing and answering question about solutions to climate change, and how they stack up. If you're interested in coming along, you can find details here: howtoacademy.com/events/how-t...

This article is just bollocks, isn't it? There are lots of good reasons not to eat many Doritos, but the carbon footprint of the corn going into them isn't one of them, because eating almost anything else would be worse. www.theguardian.com/environment/...

Does the news reflect what we die from?

NEW: GLOBAL RENEWABLES OVERTAKES COAL How the heck did that happen so quickly?!...🧵

Not nearly enough is made of the incredibly impressive feat Indian Railways has made to electrify almost 100% of its 135,000km of track, while also growing renewable sourcing. Huge: timesofindia.indiatimes.com/business/ind...

Some good news. London is meeting legal limits for toxic NO2 pollution for the first time – almost 200 years earlier than predicted – following the Mayor’s "world leading air pollution policies," City Hall announces. The Ultra Low Emissions Zone - and similar policies - really do work.

Many people feel overwhelmed with the number of potential climate solutions, and are not quite sure what to focus on. @projectdrawdown.bsky.social has always been at helping people navigate the minefield. Their new explorer is really cool, and helps to make things clearer: drawdown.org/explorer

What impact do contrails from aviation have on global warming? Is there a cheap and easy way to get rid of them? There might be. In the latest episode of Solving for Climate we speak with Ian McKay, founder of Orca Sciences about this and much more. Listen here: open.spotify.com/episode/4aMv...

My new book is published today, and my cats highly recommend it. www.penguin.co.uk/books/462676...

I really enjoy the wide-ranging (and often provocative) conversations Mark Lynas has on his @weplanetint.bsky.social podcast. So I was very happy to join him again to talk more about climate change and what we do to fix it. www.weplanet.org/podcast/epis...

Imagine all cars were electric, and then one Volkswagen engineer comes up with another idea … #EMobility

This week, @MLiebreich talks to @hannahritchie.bsky.social about her new book 'Clearing the Air', busting 50 climate myths and digging into what really works (and what doesn’t). Out now 🔗 www.youtube.com/watch?v=voLb...

A decade of change. In 2014, less than 4% of the world's electricity came from solar and wind. In 2024, this was 15%. Here's how the distribution across countries has changed (+ shifted upwards) over those 10 years. Data from @ember-energy.org

"A refreshingly pragmatic and undoomy book." The Guardian just published a great review of @hannahritchie.bsky.social's new book 'Clearing the Air'. The book will be out in 2 days. If you are unsure whether you want to read it, the review gives a good overview: www.theguardian.com/books/2025/s...

Cement is responsible for around 7-8% of carbon emissions. How do we decarbonise it? This week on Solving for Climate we talk to Leah Ellis, CEO of Sublime Systems, about how we might solve for low-carbon cement. Listen here: open.spotify.com/episode/3PXb...

A key challenge for data centres/AI is that they are very geographically concentrated. See this chart from the IEA. Even if data centres are "just" 1-2% of global electricity, if you're adding a reasonable amount quickly, the local grids serving this demand are going to struggle.

Electric car batteries degrade over time, but typically less than a lot of people think. Many are still over 80% capacity after 200,000 miles. Most manufacturers are now giving 8+ years warranty. My Substack from this week: hannahritchie.substack.com/p/electric-c...

Yesterday, Google released a new report estimating the environmental footprint per Gemini query. That's very welcome, as lack of any transparency from big tech companies has been a big problem. I hope others follow suit. I wrote about on this on Substack: hannahritchie.substack.com/p/ai-footpri...

Electrification is a huge lever for decarbonisation, but for consumers, innovations can seem overwhelming + confusing. @everythingelectric.bsky.social do a great job of making things accessible. Sept 5-7 they'll be in Vancouver, if you want to geek out for a day or two: ca.everythingelectric.show

The US is building a record amount of electricity generation capacity in 2025 to meet rapidly growing demand. And its overwhelmingly clean energy, with a bit of gas. Meanwhile the Trump administration wants to stop permitting of new solar and wind projects.
