Kampfansage von Reiche jetzt auch an die Erneuerbaren: “Völlig überzogen” nennt sie jetzt den erfolgreichen Ausbau der Erneuerbaren Energien beim BDI und kündigt an: Solar, Wind & Co. müssen unattraktiver werden!

Damit widerspricht sie klar dem Koalitionsvertrag.

My latest column just appeared in Science, entitled "Free speech, fact-checking, and the right to accurate information”. (www.science.org/doi/10.1126/...) I use one of President Trump’s first executive orders to unpack the terrain between misinformation and claims to free speech 1/n
Free speech, fact checking, and the right to accurate information
True to his campaign promises, on 20 January 2025, US President Donald Trump signed a broad range of Executive Orders, the scope of which ranged from renaming the Gulf of Mexico to “Gulf of America” t...

As the Trump inauguration approaches, Mark Zuckerberg announced that Meta is changing its content moderation policies. They are doing away with fact-checkers and will instead implement community notes similar to X/Twitter’s. I think this is a bad idea.

"...A broken and paranoid America—splintered by the incapacity to agree on observable facts, or trust the institutions we depend on to solve major problems—tumbling into the worst version of a climate catastrophe: That’s a future almost too grim to contemplate..." tinyurl.com/5n8mupt8
Trump won't confront the climate crisis. He'll feast off it.
Floods, fires, financial collapse—the MAGA crowd can't wait.

The Atlantic reports about two worring cultural trends that seem to pull human societies back into a pre-modern state of self-imposed immaturity: Anti-scientific (far right) mysticism and anti-secular religious extremism.

Anti-science mysticism is enabling autocracy around the globe.

Pretty unsettling but also sort of reassuringly material set of threats that are barrelling down the road for the US, in the Drilled newsletter -->

The carbon capture and storage (CCS) boom is neither a greenwashing campaign nor a genuine attempt to tackle carbon emissions, it has been driven almost entirely by the industry's increasing reliance on EOR to deal with oil fields in decline. Compressed carbon turns out to be the best way to get dwindling oil reserves out of the ground, but it's also one of the more expensive methods. Solution? Re-brand the process as a climate solution and get taxpayers to fund it. That is what the 45Q tax credit, passed as part of the Inflation Reduction Act, is all about. (For more on that, we did a deep dive here.) 45Q has also been a lifeline to the corn ethanol industry, a terrible idea that just won't die (but, as Emily Grubert has pointed out, is a great illustration of the fact that policy can do things). Worth pointing out here that a one-acre solar farm produces as much energy as 100 acres of corn-based ethanol. There are currently tens of millions of acres of corn going toward ethanol production in the U.S., which has an impact on soil, water, and chemical usage as well as emissions. It is easier and cheaper to do CCS on a corn ethanol plant than lots of other plants, which makes 45Q a huge boon for ethanol producers. Connecting CCS to corn ethanol also helps the fuel qualify as a "sustainable aviation fuel," opening up more markets and government subsidies for the stuff.
