A deadly climate change effect is even worse than feared, study finds Sea level along the world’s coastlines is often much higher than previously assumed, a new study finds.

Best time to fight this was yesterday. Second best time is today.

Don’t wait until tomorrow. Don’t wait for someone else to fight. It will be too late.

It’s one thing for the government to reject @AnthropicAI’s terms—- and entirely another to banish them permanently (and, absurdly and punitively declare them a supply chain risk) in favor of someone else who took pretty similar terms and happened to have given more campaign contributions.

Marilyn (Molly) Marcus, 1942-2026 Some things I learned — and still hope to learn — from my mother

I don't normally share the news of people's loved ones passing. I have yet to become comfortable with how social media handles this. But this essay by @garymarcus.bsky.social in honor of his mother is too wonderful not to share widely.

America, and probably the world, stands on a precipice. Call you Congresspeople, right now.

The most urgent plea I have ever written. Please read and share.

If I could, I would like your attention for a moment. This post from @garymarcus.bsky.social is exceedingly important-please read it, share it, and take action.

America, and probably the world, stands on a precipice. Call you Congresspeople, right now.

The urgent plea of @garymarcus.bsky.social demands rapid action: the US Military, in the hands of fascists, seeks to bend Anthropic to the knee in the aims of incorporating AI into military weaponry. Gary asks us to call our political representatives right now. I just did. Now it's your turn.

Embedding unreliable AI deep into the source code of the military without human oversight is the single stupidest thing we could do as a species.

And that is *exactly* what the United States is about to do.

I will never not be angry at the way tech bros have told us that the danger is apocalyptic superintelligence when it was always obvious that the reason to worry is that we would put dumb AI in really stupid places.

Netflix Backs Out of Bid for Warner Bros., Paving Way for an Ellison Takeover

The richest man owns X.

The second and third richest men control Google.

The fourth richest man owns Facebook, Instagram, and WhatsApp.

The fifth richest man owns The Washington Post.

And now the sixth richest could soon take over both Paramount and Warner Bros.

See the problem here?

#WEFDavos So the crème de la crème of global leaders is listening live in the room. What will they say to him?

Klima: CDU will den Begriff „klimaneutral“ neu definieren Wirtschaftsflügel und Arbeitnehmervertreter der CDU wollen die Klimapolitik neu justieren. Der Bundesparteitag soll den Kurswechsel absegnen. Trotz allem: Die Partei ist gespalten wie nie.

Quelle: www.handelsblatt.com/politik/deut...

Europa muss sich der Realität stellen: Wir haben kaum Öl und Gas, aber dafür eine moderne und innovative Industrie. Zukunft erfordert hohe Investitionen – und damit politische Verlässlichkeit.

Großangriff aufs Klima.

In seltener Einigkeit wollen Wirtschafts- und Arbeitnehmerflügel der CDU das zentrale Klimaziel der EU schleifen.

Das Versprechen bis 2050 der erste klimaneutrale Kontinent zu werden, soll auf den Müllhaufen der Geschichte.

Dazu darf es nicht kommen.

Angesichts des russischen Angriffs auf die Ukraine war die rasche Abkehr von russischem Gas richtig. Doch nun gilt es den Europäischen Green Deal umzusetzen und fossile Energien durch Erneuerbare zu ersetzen. Es ist fatal, dass die Merz-Klingbeil-Regierung die Energiewende in Brüssel ausbremst!

Die Grafik zeigt die Entwicklung der Flüssiggasimporte (LNG) aus verschiedenen Ländern in die EU. Der Anteil der USA ist von rund 25% in 2021 auf 60% in 2025 gestiegen.

Trumps Zoll-Drohungen zeigen: Die von der Leyen-Zusage für 750 Mrd. Dollar zusätzlich fossile Energie in den USA zu kaufen, war ein irrer Fehler. Eine weitere Erpressbarkeit ist entstanden. Wir müssen uns von fossilem Gas & Öl befreien. Wärmepumpe und grünen Wasserstoff verbreiten statt ausbremsen!

What's happening in your country is frightening, and it is frightening us here in Europe as well. But I am deeply impressed by the wit and clarity of your political analysts and by the determination of people doing the right thing

Cyclones, floods and wildfires among 2025’s costliest climate-related disasters Christian Aid annual report’s top 10 disasters amounted to more than $120bn in insured losses

"The bill for extreme weather damages will continue to rise until the world slashes greenhouse gas emissions and phases out fossil fuels."
What some don't understand: it will rise disproportionately as resilience limits of infrastructure are increasingly exceeded.

Not sure I understand why the Trump administration cares about Christians in Nigeria and not Christians in Ukraine

Experts warn ongoing concern with Atlantic Ocean will be direct threat to dozens of nations: 'Consequences for at least 1,000 years to come' "A huge responsibility for the decision makers of today."

A recent study by Dutch colleagues shows that a shutdown of the Atlantic overturning circulation #AMOC could bring extreme drought to Europe for centuries.
That is a thus far underappreciated risk of climate change.

An earlier version of the NSS specifically said that the US should try to pry Italy, Austria, Poland and Hungary away from the EU

Thank you for discussing how people who agree with each other should talk about this. But where can I find wisdom on what to do about it all? Hello from Amsterdam by the way

Trump's national security strategy is out and some of the Europe sections are shocking. "...the growing influence of patriotic European parties indeed
gives cause for great optimism."
www.whitehouse.gov/wp-content/u...

The new National Security Strategy is a propaganda document, designed to be widely read. It is also a performative suicide. Hard to think of another great power ever abdicating its influence so quickly and so publicly. It will be worth following the reactions around the world, not just in Europe.

thanks so much!🙏🙂

Germany’s Top Research Institute Confirms What Critics Said All Along About Gaza For two years officials in Germany dismissed Gaza’s death toll as propaganda. Now the Max Planck Institute released estimates that make such denial impossible – and echo the patterns of past genocides

For two years officials and media in Germany dismissed Gaza’s death toll as propaganda. Now the Max Planck Institute released estimates that point to the same patterns seen in past genocides. Latest on my Substack
