I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely

I really like the term ā€œcontext engineeringā€ over prompt engineering. It describes the core skill better: the art of providing all the context for the task to be plausibly solvable by the LLM.
