Animations were regularly drawn by scientists on a whiteboard (The Board of Lies) we used to track ops at sea. Webcam grabs automatically archived… and a flip-book was born. I think that was more about boredom than necessity, but maybe there is also a lesson in there about “use the tools you have?”
This is one of the last days I get to post these absolutely curséd animations I made for eel facts season. I think I'll post them in a thread here for posterity.

COP30 TEXT ANALYSIS: One way to read dense COP text is to focus on the verbs. These are helpfully italicised – and for good reason.
MOSTLY INACTIVE: Carbon Brief analysis of the “global mutirão” text finds 69 inactive verbs, requiring no action, against 32 active verbs.

AMOC weakening declared a national security threat
Iceland has declared the AMOC a national security threat and an existential risk in the coming decades, enabling its Government to prepare for worst-case scenarios. Should we be worried?
