RIP Professor Loureiro - known for his research on how plasma works, particularly the physics underpinning astronomical phenomena. He was studying how to harness fusion power to combat climate change. He leaves behind a wife and three children.

More than half of the “city killer” asteroids that might threaten Earth remain undiscovered. With an infrared eye, NASA’s NEO Surveyor aims to find them. Learn more: https://scim.ag/44snoxl

Die Domain DesideriusErasmusStiftung.de wurde mir vor Jahren geschenkt. Seitdem frage ich mich, was man damit machen kann. Vermutlich ist es das Beste, dort @correctiv.org Content hochzuladen und über diese AfD-nahe Stiftung aufzuklären. 😀 Also: Hier unser kleines Weihnachtsgeschenk für euch alle 🤝

Oben Bleiben! #Stuttgart21

Das Paris-Abkommen & das damit einhergehende Klimaziel war ein großer diplomatischer Durchbruch. Es war schon damals klar, dass freiwillige Verpflichtungen nicht ausreichen würden, um die Temperatur-& Emissionskurve nach unten zu biegen, so PIK-Direktor Edenhofer 👇 www.radiodrei.de/programm/sch...

Frau Reiche #BMWE hat offensichtlich Angst, daß Akkus den profitablen Netzausbau und die Nutzung der Gaskraftwerke kanibalisieren. Akkus über 100 MW sollen aus der Anschlussverordnung (KraftNAV) fallen. Es gibt kein alternatives Genehmigungsverfahren: 51 GW Speicher vor dem Aus

Irgendwer* verhindert die Energiewende, damit noch länger Gas verkauft werden kann. *Gas-Kathi Reiche vielleicht?

The White House's new National Security Strategy justifies isolationism, lacks attentions on nuclear risk, mentions climate change once, and addresses disruptive technologies mostly in terms of competition. Alexandra Bell @atomicbell.bsky.social provides analysis: buff.ly/57fhXJj

Another extraordinary warm spell in EUROPE With MINIMUM temperatures 6/10C in Scandinavia and Baltic countries with hundreds of records of winter warmest night. Thousands of records have fallen everywhere in Europe these weeks,with the exception of Italy.

More from the coalition of planet destroyers: “After the objections of the U.S. official, as well as some from Saudi Arabia, Iran, Russia and other oil and gas producing nations, the summary for policymakers language was dropped entirely rather than renegotiated.”

Indonesian authorities report that nearly 1,000 people have died and nearly one million people have been displaced by extreme rainfall that flooded coastal and highland areas, triggering landslides. From @afp.com

Zukunft als Industriemuseum... Und alles mit Ansage. Meinen Studierenden sage ich, dass Verbrennen ein Relikt aus der Steinzeit ist, das längst nicht mehr in das elektrische Zeitalter passt. Das wäre doch ein Gegen-Narrativ: Verbrennen = Steinzeit.

Climate denial is a crime against science, the truth, and knowledge .. and a crime against humanity, society, our families, and future generations. What a deplorable group ... one of deviant behaviour ... people are dying, and more in the future! ClimateBrawl

This is what climate change looks like. Like recent floods in Washington, Texas, & North Carolina - a warmer atmosphere can hold/dump more moisture/rain. It is worsening as planet continues to warm. www.washingtonpost.com/weather/inte...

This is incredible (good news too): “After a 40% fall in 2024 in battery equipment costs, it’s clear we’re on track for another major fall in 2025…The economics for batteries are unrecognizable, & the industry is only just getting to grips with this new paradigm” www.pv-magazine.com/2025/12/12/b...

As an avid observer of algorithms I think I’ve figured out part of what happened here. FB now explicitly looks for and directs posts you’re opposed to into your feed, to rage-bait engagement. So now my posts are being actively boosted into people’s feeds of who reject climate. Ha! 😄😵‍💫

As we move into the final days of the year, 2025 has just overtaken 2022 as warmest year-to-date for Central England. Given the forecast, it looks likely that 2025 will end up being the warmest calendar year for this region since records began in 1659. The top 3 warmest will be 2022, 2023 & 2025.

RECORD HEAT IN BANGLADESH Exceptional high temperatures for mid December In particular 32.0 Bandarban 31.5 Khepupara were just 0.1C from their monthly records,but which was recorded in the beginning of the month. More than a dozen stations >30C. Never happened so late.

Actual climate scientist here. 2.5C is on the optimistic end of the literature on current policy outcomes, which spans the range from 2.3C to 3C. I wrote a review of the literature on the subject earlier this year: journals.sagepub.com/doi/10.1177/...

There is some nuance here, as fossil CO2 emissions have continued to rise while total CO2 emissions have been relatively flat: www.carbonbrief.org/analysis-fos...

“China’s government has made fusion a national priority, marshaling resources at daunting speed. Fusion could change the calculus for both nations and the globe. Whoever conquers it could build plants around the world and forge new alliances with energy-hungry countries.” 🧵 1/3 #FusionEnergy #China
