I am SO late to this but this @emdashsanders.bsky.social piece (edited by @emorwee.bsky.social) is great: a deep dive into Exxon's use of dodgy CCS promises to justify fossil gas fuelled power stations to run data centres A set of keywords that makes me click so hard my mouse shatters into pieces 💥

Great thread to bring in 2026.

The CO2 Newsletter, (1979-1982)- by the late William N. Barbat, a geologist who "got it," is a revelation . Enraging (b/c scientists - & some politicians - knew, but couldn't get the action that was needed to happen.) Terrifying too, obvs. All 18 issues will go up this year. First one, Mon Jan 5.

"Many K-12 teachers in the US feel ill-prepared to teach about #climate change & sustainability... perceived barriers of teachers to CC professional development... teachers ranked lack of time to attend – not controversy or lack of knowledge – as the primary barrier for participating in the CCPD"

How to turn a mirrored glass office building (left) into stone clad apartments (right) Adaptive reuse of 15,700m2 of offices into apartments with new stone, timber and wood-fibre insulation loggias on the outside. By Nicolas Dorval-Bory, Jean Christophe Quinton and Guillaume Ramillien

2025 was indeed a rough year for climate science in particular, and science in decision-making more generally, so it’s good to look back an appreciate the progress made despite the major geopolitical headwinds. Thanks @thierryaaron.bsky.social for putting this thread together. 👇👇👇

This year has been brutal for the #climate movement. Rollbacks, repression, & outright denial, especially in the US, have made progress feel fragile & uneven. Which is exactly why it matters to pause & look back at what did move forward in 2025. Here are 12 real wins 🏆, one for each month 🧵⬇️

Through 2026 I will be posting all 18 issues of the astoundingly prescient "CO2 Newsletter", published from 1979 to 1982 by the late William Barbat. Here's a clipping from Vol 1, No 2 (Dec-1979) Can't say we weren't warned, eh?

"The hot drought conditions that drive elevated tree mortality are projected to frequently emerge during a typical dry season 20 to 40 years from now" #ClimateEmergency

9️⃣ Energy transition expert @tessakhan.bsky.social explains how UK dependence on foreign dictators for gas and oil has pushed over 12 million households into energy poverty—and why upgrading to homegrown renewables will make us so much better off. More info: www.nebriefing.org/take-action #NEB2025

8️⃣ Green policy expert @angelaisfranc.bsky.social on why the Government urgently needs to rewrite the rules, which currently favour polluters, and deliver the enormous benefits that a transition to a post-fossil-fuel economy will bring. How you can help: www.nebriefing.org/take-action #NEB2025

7️⃣ Lt General Richard Nugee CB CVO CBE with a stark warning all MPs must hear: "We are facing the potential of 𝗮𝗻 𝘂𝗻𝗴𝗼𝘃𝗲𝗿𝗻𝗮𝗯𝗹𝗲 𝘀𝘁𝗮𝘁𝗲 unless Government takes this seriously" Gen Nugee also explains how acting now will make our nation so much more resilient. More info: www.nebriefing.org/take-action

6️⃣ Leading intensive care doctor Professor @hughmontgomery.bsky.social OBE: "The climate emergency IS a health emergency" Prof Montgomery also outlines the enormous benefits if we take bold action. What you can do: www.nebriefing.org/take-action Full talks: www.youtube.com/@nebriefing #NEB2025

5️⃣ @profpaulbehrens.bsky.social of @ox.ac.uk with a vital message for MPs & the public. "If we don't lead this change on the front foot, we'll be forced into it anyway as food shocks intensify." What you can do: www.nebriefing.org/take-action Full talks: www.youtube.com/@nebriefing #NEB2025

4️⃣ Professor Tim Lenton OBE of @exeter.ac.uk warns that if we cause the #AMOC ocean current to collapse, which could happen at 2°C, we could see winter temperatures of -20°C in London and -30°C in Aberdeen. More info: www.nebriefing.org/take-action Full talks: www.youtube.com/@nebriefing #NEB2025

3️⃣ Professor @hayleyjfowler.bsky.social of @newcastleuni.bsky.social warning that the mega floods seen in Europe could happen here, and that we're not prepared. We need emergency action more than ever. What you can do: www.nebriefing.org/take-action Full talks: www.youtube.com/@nebriefing #NEB2025

2️⃣ Professor @kevinclimate.bsky.social: we're using up the carbon budget for staying under 2°C at 0.7% every single month, with a small but very real risk we could reach a catastrophic 4°C by 2100. There are huge benefits for the majority if we address climate change. www.nebriefing.org/take-action

1️⃣ Professor Nathalie Seddon of @ox.ac.uk explains why nature is critical infrastructure. "This is national security issue. Without a living, healthy biosphere, there is no stable economy, no food..." Yet taking action will make us better off. More info: www.nebriefing.org/take-action #NEB2025

Battery pack storage costs for WindWaterSolar are dropping so low that they eliminate the argument for using fossil fuels or nuclear moving forward. Battery pack prices for stationary storage now down to $70/kWh in 2025, a 45% decrease in just one year. www.ess-news.com/2025/12/09/b...

With estimated battery system costs of $60/kWh by 2035, electrification of all energy plus use of WWS+storage reduces 2050 annual all-sector energy costs to the world by ~60% web.stanford.edu/group/efmh/j...

Dr. Mark Peifer (@peiferlabunc.bsky.social)argues that understanding the history of eugenics is critical for up-and-coming geneticists and should be included in college curriculums. www.cell.com/news-do/pr-e... @cp-trendsgenetics.bsky.social

Powerful Guardian editorial on urgent need for #climate adaptation & for “real plans, real finance, real justice”. And good to see shout out to work of @climatemajority.bsky.social & GlacierTrust showing adaptation as both essential in itself & as a spur to greater decarbonisation👇

I’m very thankful to Stephanie Maltarich at @cires.colorado.edu for this writeup about efforts to reform how scientific fieldwork operates. To make it less hostile & exclusionary, and *actually* safer. From our research talks @ AGU about this subject. The work is ongoing. #disability 🧪

"Targeting a #climate resilient, sustainable world involves fundamental changes to how society functions, including changes to underlying values, worldviews, ideologies, social structures, political and economic systems, and power relationships" - @ipcc.bsky.social www.ipcc.ch/report/ar6/w...

this is a very interesting topic, but the reason it's maybe my favourite episode of the year is all the other things it touches on regarding grid modernization, vpps and market structure.

Extinction rarely departs with drama, it slips out the back door while we’re still debating the guest list. These records are made official on the Red List. "Conservation failures are often recognised only once they can no longer be reversed." via @mongabay.com: news.mongabay.com/short-articl...

"We show that most ESMs inaccurately simulate terrestrial biological nitrogen fixation, differing from a new global synthesis of terrestrial BNF measurements across natural and agricultural biomes... As a result, ESMs could exaggerate plant carbon uptake as atmospheric CO2 concentration rises"

The democratic paucity of the Westminster system means MPs have almost no say over trade policy, leaving it to be shaped almost entirely by big business - including the world’s oil giants. open.substack.com/pub/abolishw...

One thing 2025 made clear: Durable progress on climate in the US will require structural reform to our corrupted political systems. Otherwise, steps forward will always be vulnerable to the bloody clawbacks we saw this year. A political strategy that doesn't center system reform is not "pragmatic."

'Climate pragmatism' is logically broken for many reasons but among the worst imo is: (a) arguing against limiting fossil supply, bc cheap solar + free market will sort it out but (b) supporting data centre growth so new clean energy DOESN'T cut down on fossil demand, and just meets growth instead

During its worst drought in a century, Iraq signs a water security for oil deal with Turkey. The once rich Tigris & Euphrates rivers are drying up from climate change & mismanagement, leading to crop losses & a water crisis. edition.cnn.com/2025/12/21/c...

"Just as we once banned tobacco ads to protect people from a deadly product, we must now do the same with fossil fuels, which are driving a global health crisis through air pollution, #climate change, & environmental degradation" - @drelainemulcahy.bsky.social, @ukhealthclimate.bsky.social

The thickness of #Arctic sea ice dropped to a new all-time record low this year around the North Pole (data from PIOMAS). More in my latest 'climate viz of the month' blog: zacklabe.com/climate-viz-... #OpenScience #SciComm #DataViz #OpenData

[FOUNDER'S BRIEF - @rhettayersbutler.bsky.social] In France’s Dauphiné Alps, Fabien Quétier leads a Rewilding Europe project as wolves, beavers, and other wildlife return. Rewilding, once utopian, now feels urgent as droughts and heat rise. For Quétier, the real gamble is doing nothing.

AMOC "was the really big story of the year"—shocking even scientists working on it. @djspratt.bsky.social & I review '25's climate reality: from COP failures to the UK National Emergency Briefing filling Westminster Hall. Essential👇 https://youtu.be/nJxh0UL3rGc #ClimateScience #AMOC #ClimateCrisis

Funny thing though: Musk and the other tech lords are still saying such things, and the media credulity has not lessened one whit. And they are richer than ever.

Today's column is on the relentless march of blithering idiocy, which includes denying climate science while your house is - literally in this case - burning down. www.theguardian.com/commentisfre...

A new study finds moist tropical forests in Australia have flipped from carbon sink to source—the first documented case of its kind. Nearly 50 years of data show tree deaths doubled around 2000, outpacing new growth as climate change and cyclones push rainforest species beyond their limits.

Where the world’s electricity comes from. Looking forward to the update including 2025.

Today on Volts: you've probably heard that Australia has cheap rooftop solar power. You've probably also heard some rumors & myths about it. (Is it destabilizing the grid?) I called my favorite Australian energy expert to clear it all up. This is a fun one! www.volts.wtf/p/whats-the-...

“You want to have some bright people work through scenarios of how [AMOC collapse] could interact & cascade across society... we’re only just starting to, with minimal trust foundation kind of financial support, no public money... which is a bit odd.” - Prof. Tim Lenton @gsiexeter.bsky.social

" The guidelines recommend that museums should “Transition away from sponsorship from organisations involved with environmental harm (including fossil fuels), human rights abuses, & other sponsorship that does not align with the values of the museum.” "

Yes, this is important in systematic change. And it’s late, late, but better late than never. Honoring work of the late great #PollyHiggins and my colleagues #cormaccullinan #michaelaclayton #janglazewski #terrywinstanley #michellemaloney #carterdillard theconversation.com/environmenta...

Today, @gijn.org publishes our final installment of our new Giude to Investigating Fossil Fuels, on looking into the industry's plans for the future — and the unlikely scenarios that it willingly renders itself obsolete or fully transitions to renewable energy sources.

From @gijn.org's guide on investigating fossil fuel greenwashing: "Companies have increasingly invested in PR & research that helps tilt the conversation about climate solutions in favor of the industry’s preferred solutions: over-hyped technologies & policies that don’t actually reduce emissions."
