Record high ocean temperatures continued across the North Pacific in October 2025, with recent warming really amplifying since the early 2000s.

It would be nice to see a bit more incredulity about AI generally.
Scientists just called out Ursula von der Leyen for claiming that AI will match human reasoning by 2026. Her "evidence" consisted, it turns out, of CEO statements from OpenAI, Anthropic and Nvidia. Not research. Marketing materials. 🧵
