A periodic reminder that the £51.1 billion that the Truss and Sunak governments spent on subsidising natural gas consumers in 2022-3 was the biggest subsidy that the UK has spent on anything ever, and a large cause of our present national debt. obr.uk/box/the-cost...

Three of the 5 splits in the Burnham cabinet identified by the FT political correspondents are to do with climate policy Rosebank, the electric vehicle mandate, Heathrow airport expansion all pitch traditional industry models against the reality of climate breakdown www.ft.com/content/b04b...

Pretty stark move from European Commission to prepare for 3C of warming. What is left unsaid is can you really prepare for 3C of warming if that means climatic tipping points? www.businessgreen.com/news/4537952...

Some green stuff to look out for in the Budget... Gas standing charges are to be axed. This is good news that will save most people some money and will strengthen the financial case for switching to heat pumps. www.businessgreen.com/news/4537978...

Whenever I read Justin Webb I remember the BBC stopped someone from hosting a podcast that was basically “I like heat pumps - they’re just neat!” because it was too political for a presenter
The problem with Justin Webb’s position at the BBC is not just his flagrant bias, or his writing for the Mail, or his audible prejudices, it’s that all those things make him embarrassingly bad at analysing politics. “Left = firebrand = too woke = trouble for Dems” is about his level

The thing with 1.5C was that it was always "overshoot". It has just taken 10 years for people to admit that nearly all 1.5C scenarios in SR15 were "overshoot" (not that anyone has really admitted that). 2C, you didn't need overshoot then and you don't need it now.

The IPCC assumes that we will see *massive* increases in carbon removal. This is reckless, unwarranted, and irresponsible. drawdown.org/insights/her...

The scenarios with crazy amounts of carbon removal (high-low, medium-low, and low-negative) are all designed to explore what overshoot scenarios would look like (as well as to model the physical climate effects of overshoot). You need far less if you don't try and reduce temperatures after net-zero

I feel like society is actually crying out for more people to be against bad things, instead of even more people just being indifferently In Support of More Large Objects, which just isn't really inspiring Feels like most of the truly inspiring recent moments are People Being Against Bad Things

But have you considered if we just decided to pollute more on a technicality? Surely the atmosphere wouldn’t mind then? www.theguardian.com/environment/...

Hadn't appreciated how much greater the depreciation/operation cost already is for Distribution (£180 per billpayer) than for Transmission (£15) These costs still smaller but not insignificant compared to the wholesale cost of the gas (£420) that passes through them
Keith Alexander reposted
Replying to @wiilp.bsky.social
Must come a point where it is cheaper for gas distribution to be switched off to an area (with help to electrify), than to dig in new gas pipes that have to be repaid over very few years. But commercial incentives aren't aligned for gas and electric DNOs to work together and share those savings?

"...we cannot be confident that temperature decline after #overshoot is achievable within the timescales expected today. Only rapid near-term emission reductions are effective in reducing climate risks."

I spent all day writing the thread in my head about how Bolsonaro's win was the culmination of a 20-year project to end Brazilian democracy, with the participation of both domestic elites and foreign actors like the US state department and Meta. This is all true, of course, except he didn't win.

I don't know that there is a template or a "secret sauce" or a clear-cut lesson to take from this. But if there is one it's the idea of treating social media as the hostile territory that it is, of actually acting like you are a participant in propaganda warfare and not like a consumer.
A great relief Lola won, but I hope that there is also someone who can beat the Bolsonaros at the next election too… www.theguardian.com/world/2026/o...

The gap between the climate we hope for and the climate we're on track for is widened on the one hand by new fossil fuel developments, and on the other by a better understanding of just how much danger we were already in.
1/5 The green & blue pathways very likely have overly optimistic assumptions about: - climate sensitivity - carbon-cycle feedbacks - scaling carbon dioxide removal - methane cuts The four papers in this thread 🧵 explain why we’ve been underestimating how little room is left.

BBC report sanitises the overt racism: It notes that organisers warned marchers not to talk to journalists, then gives the "anti-immigration group"'s own sanitised description of itself. It does not report they chanted "England for the white man" in the streets. www.bbc.co.uk/news/article...
Developing new gas fields is pragmatic. Atmospheric physics however, is an uncompromising idealist. www.theguardian.com/commentisfre...

Just 2 days after telling us they're committed to making the crisis worse by greenlighting more fossil fuel extraction, the government is now telling us it's our responsibility to prepare for the impacts of the climate breakdown that's already upon us A shameful abdication of responsibility

The amazing thing is that he isn't getting Copilot to do it from scratch - it is very much the direct plagiarism thing I have been talking about!!! bsky.app/profile/keta...
This is a good illustration of how so much of AI theft isn't indirect (ie, data sucked into a model to train the chatbot) - it's actually **direct** copying, but *enabled* by GenAI. Of course it is: chatbots absolutely suck at creating good, new stuff.

The first genuinely honest ad for generative AI I've ever seen, from Microsoft / CoPilot A mediocre white guy sees his non-white colleague getting praised for good work, he asks AI to *literally copy it*, and then he gets all the praise instead: www.ispot.tv/ad/SoDi/micr...
I am stunned 😧. Rosebank, which Ed Miliband previously referred to as “climate vandalism”, contains “only” 480 million barrels of oil. The licence has been granted to an Israeli oil company.
Meanwhile... "the foreign secretary has approved new drilling in the Sea Lion field, which is estimated to hold 1.7 billion barrels of oil and expected to start producing from 2028."

Climate comrades who are closer to these upcoming questions tell me they are feeling more upbeat, so that’s somewhat encouraging anyway. Fingers crossed everyone 🤞🤞🤞
Turns out we are on the bad timeline, and the dispiriting interpretation of Ed Miliband being bounced out of the department for energy security and net zero was the correct one. How much worse could it get now? Decisions coming up on: 🛢️ Rosebank drilling (Jackdaw is gas) 🪫 weakening ZEV mandate

The juxtaposition between Jackdaw approval and today's UN report warning the world is on track to far exceed 2C of warming even if all current net zero plans are delivered is beyond stark. www.businessgreen.com/news/4537621... www.businessgreen.com/news-analysi...

The bad arguments that the gov have made to defend Jackdaw (and potentially Rosebank) are the same bad arguments for continuing with new fossil projects. If Jackdaw is good ("homegrown gas"), why is the next new gas field bad? The gov's position is now worryingly unclear.
Earlier this summer, leading climate experts called on the government to use the decisions on Jackdaw and Rosebank to develop a roadmap to ‘defossilise’ the economy. If these projects are approved, make it clear they’re the last. Where’s that plan? www.businessgreen.com/news/4534641...

Ambitious but very welcome attempt to quantify the avoided harmful pollution thanks to climate policies here: between 0.6 - 1.8 gigatonnes of CO2-e We don't make anywhere NEAR enough noise about how much suffering we've stopped by preventing fossil fuel use as a precursor to preventing more of it

"Electric vehicle sales are increasing rapidly, but so too are road transport emissions" The *very* bad habit of only presenting market share as the core metric here means few have any idea how badly transport emissions are rising. There is a real and deep disinterest in the climate aspects
