Heading South
Tomorrow, I’m heading south, though more correctly, I’m first heading north to head south. Fieldwork in Antarctica starts next week..

The first step in the ~14,500 km journey (as the crow flies) to Wasa was a taxi to the airport. The second is a flight to Oslo*.

Time to stop writing articles about the "security" or "economic" reasons to capture Greenland, they are irrelevant
Not everyone believed me when I wrote that Trump wants Greenland becuase it would make him feel important, but that's what he told the NYT:
When asked why he needed to possess the territory, he said: “Because that’s what I feel is psychologically needed for success"

The EU needs to send a very strong message to the US that niceties are over. Disconnecting X would be a good start.
Threatening to disconnect Elon Musk's X in Europe would be unprecedented, but it might be time to play that card
Musk Won’t Fix Grok’s Fake AI Nudes. A Ban Would
When Julie Yukari posted a New Year’s Eve photo in a red dress with her cat, she didn’t expect X users to tag Grok asking it to undress her. Within hours, nude AI-generated images of her had spread across the social-media website — without her consent and without consequences.

There’s a lot of talk about whether Denmark would/cpuld “defend” Greenland against a hypothetical US invasion.
FFS
That’s not the real question. The real issue is whether Denmark would ask the EU for Russia‑level sanctions — and whether the EU would do it.
Both yes.

“If you are a 75-year-old professor reading this, now would be a good time to take emeritus status. It’s something that a lot of people could do that would contribute enormously. The job market for young people would be in much better shape if most people over 75 retired.”
