The Atlantic’s “conveyor belt” is slowing.
New observations from 16.5°–42.5°N show a two-decade, basin-wide decline in deep western overturning, the first robust observational evidence that the AMOC is weakening, confirming long-standing model predictions.

Putting aside Sam Altman just continuing to emit huge lies constantly, this is an amazing example of what I mean when I talk about how GenAI is replacing *extremely low energy* digital tasks with *WAY WAY HIGHER ENERGY* replacements that *do not even work*
Why TF is anyone using ChatGPT as a timer!
I don't remember seeing an image of Earth before that captures the (thin, fragile, tiny layer of) atmosphere so clearly. I mean, look at that.

A close up image of the head of a Ring-necked Parakeet showing its bright green plumage and red bill. Wording alongside reads: Origin of the UK’s Ring-necked Parakeets finally revealed!
1/ Forget tales of escapees from the film set of The African Queen. Ignore rumours of Jimi Hendrix’s supposed liberation of a pair on Carnaby Street. Newly declassified documents from the Ministry Of Defence reveal how Ring-necked Parakeets colonised the UK through Operation Norwegian Blue! 😮 🪶

In Greenland's Scoresby Sund, a beautiful iceberg floats in front of distant mountains painted in warm light. A glorious morning, as we sailed on calm waters surrounded by crackling ice & towering mountains!

I just did the dumbest thing of my entire career to prove a much more serious point.
I tricked ChatGPT and Google, and made them tell other users I’m a competitive hot-dog-eating world champion
People are using this trick on a massive scale to make AI tell you lies. I’ll explain how I did it

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes!
"Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."
Aurora Borealis, from the middle of Amsterdam. Visible with the naked eye. Truly exceptional from this light polluted part of the Netherlands. Go outside if you can! #auroraborealis #noorderlicht
I research dictatorships for a living and have spend a non-negligible amount of time reading the words of madmen like Gaddafi, Hitler, and the Kims of North Korea. Even to me this is fucking bunkers.
The ICC is under U.S. siege, the majority of Dutch journalists don’t seem te care. The new MAGA world order is here.
That was, unfortunately, no different here. Over time, fireworks had, more than anything, become a topic of identity politics. Recently, bc of extremely visible negatives (warzone scenes and attacks on first aid responders), we've reached a point where a full ban is in place from next year. Hope!
We do! And have been doing it for more than half a century already. ;-)
Thanks for sharing! Somehow I had never come across that Taylor Texas video. Shocking. That one is going into my future talks on the topic.
On the other Dutch radar it is very clear birds are fleeing away from fireworks towards quiet places like the Wadden Sea and IJsselmeer (a huge inland lake). See the patterns of reflectivity moving towards the East/ESE.

Happy New Year! 🎆
As expected, sadly, the radars once again lit up with MILLIONS of birds fleeing from #fireworks.
