Heizung und Motor sind jetzt wieder Privatsache - aber für billigen Kraftstoff soll natürlich der Staat sorgen…

Klimapolitik der Bundesregierung: So begräbt die Regierung ihre Klimaziele In nur neun Monaten hat die Koalition den Klimaschutz enorm geschwächt und vieles abgeräumt, was mühsam erkämpft worden ist. Sie folgt einer alten Merkel-Regel.

Die Bundesregierung verabschiedet sich mit Schwung den Klimazielen, ohne das Offensichtliche zuzugeben. Es fehlen einem die Worte. @pinzler.bsky.social hat trotzdem Worte gefunden. Harte Worte www.zeit.de/politik/deut...

Jesus this news day.

Anthropic wanted to make sure its tech wasn’t used for mass surveillance. Here’s what Hegseth did in response.

Breaking: Washington Post gutting its climate team Clean energy dies in darkness. Courtesy of Jeff Bezos.

I don't say this often but: I'm so proud to be a climate and environment reporter. We cover an issue that is vitally important to humanity and the natural world. 14 of my climate colleagues at the Post were laid off today and I'm devastated.

We could produce a lot of electricity on the land used for biofuels About enough to meet current global electricity demand.

"Cities, towns, and roads are seen as the big “human land use problem,” even though they only cover around 1% to 2% of habitable land. Agriculture makes up around 50%. But because it’s plants growing, it seems like a more natural part of the landscape."

The Climate Question That Economists Cannot Answer Models can predict catastrophic or modest damages from climate change, but not which of these futures is coming.

"Weitzman himself emphasized the possibility of catastrophic climate outcomes, even if unlikely and unquantifiable, as a motivation for stronger action, in part by underscoring the fragility of climate-damage estimates that appeared to justify weaker responses."

Robles abre la puerta a la participación de España en una misión de vigilancia en Groenlandia La ministra de Defensa avanza que la decisión de enviar tropas se tomará entre este jueves y el viernes: “Vamos a ver cómo avanza todo y en función de eso tomaremos decisiones”

Lo que es incomprensible es que haya un presidente de una potencia amenazando la integridad territorial de la UE y todavía quede algún país por mandar hasta el último efectivo que sea necesario.

Tienes 6 años, tu madre, que te acaba de dejar en el cole, es asesinada de un tiro en la cara, horas después el gobierno de tu país la llama terrorista y el canal de TV más visto ridiculiza su pasado.

ICE officer fatally shoots driver in Minneapolis
ICE officer fatally shoots driver in Minneapolis Video taken by bystander Caitlin Callenson shows an ICE officer fatally shooting a driver in Minneapolis on Jan. 7, 2026.

This is a video of federal immigration officers murdering a woman who was not attacking them. In Minneapolis, today.

The United States Constitution protects all people in the United States, Conservative and Liberal. Its suspension will eventually harm all people, Conservative and Liberal.

Congestion pricing after one year: How life has changed. How life has changed in the New York area, according to data on traffic, transit and the responses of 600 readers.

Congestion pricing is an unqualified success in NYC. It would be great to see it expanded to every city with decent public transit options. www.nytimes.com/interactive/...

"Eliminating fares would leave the MTA without a key source of money and raise the likelihood that bus frequency and coverage get slashed during a future crisis. A transit system without fares is a brittle one."

Super interesting work!

I agree with the need for better data. This would also allow research to back up parts of the post that suggest a causal link without any evidence (e.g. "If the 90-day rule were meaningfully shaping behaviour, density would be lowest where enforcement is tightest.").

Die USA bombardieren Venezuela, entführen den Präsidenten und kündigen an, das Land "so lange wie nötig zu regieren". Und wie rahmen einige deutsche Leitmedien das? Als kühnen Coup. Als Actionfilm. Nicht als Völkerrechtsbruch. Ein kurzer Blick in die Medien… 🧵

I understand the last year has been confusing and difficult for Atlantists, very much as the Fall of the Wall was for communists, but they have now run out of excuses to keep treating the US as part of the international order.

Agree. Do a Bluesky search on Ezra Klein. The outcome is ridiculous.

It’s fine not to like him, but the reaction is disproportionate.

To me it seems to point to unhealthy boundary policing.

Ich würde mir den persönlichen Vorwurf gg Robin nicht zueigen machen. Nicht zuletzt hat er die "Welt" verlassen, weil sie immer mehr in den Rechtspopulismus abgleitet.

Richtig ist aber die kritische Analyse der populistischen Argumentationsstruktur, die sich auf den Willen "der Menschen" beruft: /2

Ni mérito, ni solidaridad, ni futuro: os dieron un master y se quedaron con los pisos Os prometieron que esfuerzo y solidaridad tendrían recompensa. No la hay. Y las ideologías dominantes gestionan la escasez, no desbloquean oportunidades.

Hay dos generaciones enteras a las que se les exige mérito (desde la derecha) o solidaridad (desde la izquierda) a cambio de... ¿nada?

El pacto YA está roto.

El conflicto YA está aquí.

Y no lo vamos a resolver desde las ideologías de la escasez.

This is insane.

These laws apply in the EU, not in the US.

What‘s next? Do we need to copy every law passed by the US Congress to avoid sanctions?

This US government does not want allies. It wants vassal states.
