Fossil fuel subsidies are never, ever the right answer. Quite the opposite.

What does the future hold for the thawing Arctic? Two experts unpack how trends in climate and geopolitics might unfold to shape the far north.

The lovely folks @nature.com asked me to review @cryopolitics.com & @klausdodds.bsky.social's book *Unfrozen* 📘 A great introduction for newcomers to the Arctic regions, Bennett & Dodds manage to "make the complex accessible and the mundane memorable" 🧑‍🚀 ❄️

I’m old enough to remember when talking heads scolded us for supposedly being in an echo chamber over our repeatedly stated global warming concerns. Almost as if we weren’t the ones in the chamber.

What the historically low snowpack in the American West means for water and wildfire this summer Snow is a resource that will likely be in shorter and shorter supply in the years to come in the West, where researchers expect climate change to shrink snow-supplied water by about a quarter by…

"The amount of water stored in the snowpack historically peaks around April 1. But this year, the snowpack in many places was absent, or nearly so, by then—the lowest level in the 45 years since automated measurements began," writes

Decades of increased emissions from forest-fuelled BECCS - Nature Sustainability Governments are considering subsidies for bioenergy with carbon capture and storage fuelled by wood from existing forests. However, a transparent model estimates that this will probably increase emiss...

Bioenergy with carbon capture and storage (BECCS) doesn't work: "... most emissions occur before the power plant and therefore cannot be captured, and that wood has twice the carbon intensity of natural gas and generates electricity less efficiently"

Bei den Startups gibt es solche und solche, z.B. beschäftigt mit ca. 1.500 Mitarbeitenden @cfs.energy mehr Experten als das PPPL oder @plasmaphysik.bsky.social , viele kommen auch von diesen Einrichtungen, bei anderen bezweifle ich auch oft, ob die wirklich genau wissen, was sie tun

Direct Fusion Drive - Wikipedia

I am physicist, but no plasma expert, but what Pulsar Fusion is doing is just the Princeton proposal of a direct fusion drive, look here: en.wikipedia.org/wiki/Direct_... it's considered as feasible and the numbers Pulsar gives are not exaggerated for a first generation fusion propulsion system

Sánchez ist seit knapp 8 Jahren Ministerpräsident, der Mindestlohn stieg in seiner Regierungszeit um 66%. Er kontrollierte den Strompreis zu Beginn des Ukrainekrieges, und in der aktuellen Erdölkrise schnürt seine Linkskoalition ein Paket, das auch den einfachen Haushalten hilft.

WHEN the AMOC collapses, temps in Europe will drop precipitously. Scientific consensus places the date when that tipping point is reached ever closer, so, as @lassessostehen.bsky.social put it: hey Europe, this would be your actual #collapse.

Care to have a conversation about it? No? Thought so.

.. außer eine Mehrheit versteht, was da passiert, lernt mit unlösbaren Problemen und Verlusten angemessen umzugehen, v.a. auch angesichts faschistischer Erfahrungen anderer Länder. Faschismus in multiplen Krisen ist zwar die Default-Einstellung aber kein Naturgesetz.

Politik im #Kollaps handelt nicht von der Lösung der Probleme (die in vielen Fällen unlösbar geworden sind), sondern davon, Sündenböcke für all das zu finden, was nicht mehr lösbar ist.

Deswegen wird Politik im Kollaps immer dümmer und faschistischer.

Richtig, alle Sterne und technischen Fusionssysteme sind auf den Tunneleffekt angewiesen, um nennenswerte Reaktionsraten bei der Fusion zu erzielen, da zu wenige Ionen im Maxwell Schwanz der Geschwindigkeit schnell genug sind, die Coulomb-Abstossung direkt zu überwinden
