Call for papers 📢 We are co-editing a special edition of Climatic Change on how #NLP & AI are being used to drive real #ClimateAction. Edited by researchers working at this intersection inc CPR's Anne Sietsma @franticpedantic.bsky.social. Submit by 30 June: link.springer.com/collections/igbiebchhh
Square image with plain white background. "CALL FOR PAPERS" at the top centre in a navy blue, and in bigger, bold black text beneath this "NLP and AI as climate solutions". The Climatic Change Journal cover image takes up most of the space across the bottom - a wavy line formed of three different shades of blue, a little like a winding river or reminiscent of the sea. The Climate Policy Radar logo is in the bottom left hand corner, which includes a small icon of "radar" signals in blue, almost like a crop of a finger print. The Springer logo is on the bottom right hand corner, which includes a horse head like a chess piece with an orange line beneath that.

This is super interesting to read because I was very concerned about the water and AI thing so I went to my one scientist friend who literally worked on water reg/quality/usage and asked her about AI, data centers, water etc. She was far more concerned with agriculture abuses than AI.

You can place pancakes, crepes, and scrambled eggs on a simplex where the variables are the ratios between milk, eggs, and flour, (with another small axis for baking soda.) We have explored too little of this manifold. More breakfasts can exist than we have known.

OpenAI leadership are promoting a paper in Physics Letters B where GPT-5 proposed the main idea — possibly the first peer-reviewed paper where an LLM generated the core contribution. One small problem: GPT-5's idea tests the wrong thing. My technical comment: scirate.com/arxiv/2512.0... 1/
As part of a broader effort to demonstrate AI’s po-
tential in scientific research [1], OpenAI executives have
pointed to a recently published paper by Hsu [2] as evi-
dence that AI can contribute original ideas to physics [3,
4]. Hsu credits GPT-5 with proposing the core idea of the
paper de novo, possibly the first published physics article
where the main idea came from an LLM, and discusses
the methodology in a companion piece [5]. We examine
whether GPT-5’s criterion is correct.

for all talks of local-first AI, given controversies over datacenters, I don't think people are willing to hear that local LLM inference is *probably* less environmentally friendly than cloud inference the majority of the time.
