The loan scheme is designed to sit on top of the Boiler Upgrade Scheme grant of up to £9,000. This combination is what makes a heat pump affordable for a typical homeowner, so any cut to the BUS grant tomorrow would undermine the loan scheme [2]

UN Commission of Inquiry: “Israel has committed war crimes and the crimes against humanity of extermination, persecution, torture, rape and other forms of sexual violence in the Occupied Palestinian Territory, intentionally targeting Palestinian civilians as it continues to commit genocide in Gaza”

robin celikates@robin-c.bsky.social

in case you missed this: “the report found that Israeli authorities and forces continue to commit genocidal acts even after the so-called ceasefire agreement, with the intent to destroy the Palestinian people, in whole or in part” www.ohchr.org/en/press-rel...

Notably, “the report outlines the key drivers of Israeli violence and concludes that Israel has striven to expand territorially and displace Palestinians through violence since the 1947-48 war…

Military operations since January 2025 have led to the largest displacement of Palestinians in the West Bank since 1967, with 34,176 Palestinians remaining displaced as of August 2026.”

The relevant implication for mobilizers and activists is: don’t expect crises to drive a theory of change in climate politics on autopilot.

17 October 1961: “up to thirty thousand men, women, and children had been marching peacefully through Paris to protest against a curfew imposed on ‘French Muslims from Algeria’ [...] more than two hundred were killed: shot, beaten, lynched or pushed into the Seine to drown.” 23 October 2026:

‘There are currently almost 25,000 specialist riot police in France, including 11,000 full-time Compagnies Républicaines de Sécurité officers. It has often been argued, with good reason, that their mere presence incites trouble.’ Nabila Ramdani on the blog. www.lrb.co.uk/blog/2026/oc...

Important info here re likely % of fossil assets that must remain “stranded” >> 70% of fossil fuels << *need to stay in the ground* *written off* *value destroyed* restructuring of all capitalised claims on future revenue. bsky.app/profile/thie...

Dr. Aaron Thierry@thierryaaron.bsky.social

How much of the world’s proven coal, oil and gas (i.e. already found, pays to extract at today’s prices) can still be burned for a 66% chance of holding 2 °C? About 30%. The other 70%, 2,040 billion tonnes of CO₂, are stranded assets. Burn it all and CO₂ alone means roughly 2.7 °C Purple = added

those fossil assets comprise an arsenal of climate weaponry & ammunition waiting in store. We require disarmament, w legal instruments to ensure this. Put that 70% arsenal of fossil fuels completely and verifiably "beyond use"

re Finland: curious to know more…

Orla Dwyer@orladwyer.carbonbrief.org

Finland talks a lot about identifying and reforming nature-harming subsidies. Finland and Colombia are co-leading an initiative called the "friends of target 18", which looks to boost efforts on tackling these subsidies.

Horseshoe theory of scammer aesthetics: Defunded gov meets cowboy outsourcing meets entrepreneurial scammery meets AI

Steve Cicala@stevecicala.bsky.social

As scams work to look more and more like official government communications, I for one think the government should go out of its way to look less like a scam. I would sooner chew off my arm than click this link or download this app.

TY @sioldridge.bsky.social, I didn’t know this >> UK’s carbon budgets are too large/loose, based on outdated ideas about 2C warming being ok. should have been tightened in line with updated science. Didn’t happen. Why? Concerns about public acceptance. The CCC said this privately in 2022.

Simon Oldridge@sioldridge.bsky.social

The UK gov was able to approve #Jackdaw because UK targets are woefully outdated. The current ‘Carbon Budget’ was set 15 years ago back when 2°C of warming was considered ‘safe’. It wasn’t tightened as the threat picture worsened due to concerns about public acceptance.

Baked-in high per capita energy consumption will do that to a country. esp when based on *burning stuff* an economy saturated (more than most) in motor vehicle dependency Baked-into the built environment. Comparatively difficult to undo (concrete, asphalt, low density) a cautionary tale.

New from me: The US has faced a higher cost than any other country from the global Hormuz oil shock, with the crisis adding $160 billion to its fuel bill — or $471 per person on average — despite being the world’s largest oil producer.

Sharing some (simplified!) illustrations re home heating: N home thermal energy *need* U actual thermal energy *use* C resulting energy *consumption* N = a function of climate & building fabric ("fabric efficiency") U → C function of technological efficiency (here, a gas boiler)

Here thinking about the different possible relationships between Need (N) & Use (U). N = U Sufficiency N > U Insufficiency N < U Over-sufficiency (profligacy?) N = U Sufficiency As above, N = function of climate & building fabric ("fabric efficiency"). Retrofit / insulate to reduce N.

Re-reading Polanyi for class and even if he's the lesser Karl he's got some anti fascist bangers: "Yet the victory of fascism was made practically unavoidable by the liberals' obstruction of any reform involving planning, regulation, or control."

Funny how “public acceptance” so closely tracks the interests of fossil incumbents & other capital interests whose rates of return would diminish. 🤔

‘Somehow groups as diverse as young Burmese guerrillas, Indonesian delivery riders, and French high school students have all come to think of themselves as part of a political subject called “Gen Z,” as if this were the most natural thing in the world. […] Socialists are taking note.’

The bored of deputies is not actually anti-racist

Joseph Finlay@josephfinlay.bsky.social

Today the Board of Deputies passed a resolution (118-1!) declaring the Greens a racist party. The resolution claimed that the BoD had a good record of campaigning against ‘racist parties’ . As a historian of this rather niche issue, the truth is rather different.

"...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."

nature.comOverconfidence in climate overshoot - NatureAiming for declining global temperatures can limit long-term climate risks compared with a mere stabilization of global warming, including sea-level rise and cryosphere changes.

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.

We have a pretty good understanding of the differences between GHG emission estimates, but when it comes to some sectors (e.g., land), estimates seem all over the place! Why is this? @wflamb.bsky.social has you covered... essd.copernicus.org/articles/18/... 1/

The Berlin youth organisation of the CDU has called for the deployment of military forces to *prevent* planned protests by pupils against ... militarisation. Not only an *unconstitutional* use of the army in the name of "protecting democracy" but another case of normalising fascist tactics.
