earth.nullschool.net
on mobile browsers works fine, but the app is nicer. Full screen display, persistence across sessions, text size that matches device settings. Even landscape works well. And, like the website: no ads! Links below âŹď¸

Don't want to roast this too hard because the intent is good but note how it gets framed - "AI hallucinations", "a lying AI chatbot" No: this is fraud being committed by a bunch of lawless, amoral crypto scammers. There is no "ethical dilemma": report it as a non-response from the company. Simple.

How an encounter with an AI hallucination raised an ethical dilemma
When a journalist emails a company with questions looking for answers, the least they expect is a real person to feed them the spin, half-truths or outright lies. Not a machine.

Bloomberg's X account has more than 800k followers. Their most recent post was shared five times It would basically come at close to zero cost for outlets like Bloomberg to delete their X accounts, and "We don't want to use a non-consensual deepfake abuse app as a comms platform" is a fine excuse

one takeaway from the grok noncon porn thing is that much of the media just isn't interested in an issue they can't pretend has two sides or that doesn't give them an opportunity to shit on the left. Also it would be uncomfortable to justify remaining on twitter after acknowledging it

2025 goes down as the ~3rd-warmest year on record (based on ERA5). Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

Just incredibly spineless. If this is the standard of response to a blatantly illegal invasion of a sovereign country, you can bet it won't stop there. I hope the EU has plans to defend Greenland beyond stern words.

It is hard to overstate how critical

is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.
