"One query to ChatGPT uses approximately as much electricity as could light one lightbulb for about 20 minutes."

Thanks to @darakerr.bsky.social for talking with me about the high climate cost of generative AI, Google's reneging on its climate goals, and the real existential crisis facing us on NPR Morning Edition today. www.npr.org/2024/07/10/n...

Artificial intelligence's thirst for electricitywww.npr.org Artificial intelligence is an electricity hog. Google says its total greenhouse gas emissions climbed nearly 50% over five years, mostly due to electricity that powers AI data centers.

Soil quality & management practices have NO clear influence on food nutrition, according to a new comprehensive review by the National Academies. I wish this was stated far more plainly & clearly in the report nap.nationalacademies.org/catalog/2745...

Half of the world’s population depends on synthetic fertilizers for food. We need to phase out fossil fuels but to doubt the importance of Haber-Bosch to humanity is unserious.

No silver bullets: - 4Rs of fertilizers (right source, rate, time, place)/precision ag - Nitrification inhibitors/controlled-release fertilizers - Breeding nitrification inhibition into crops - Cover crops to trap N - RE powering N fertilizer manufacture - Improve soil/water mgt where yields are low

What you probably *didn't* know, is that we still have a really poor understanding of HOW or WHY crop yields decline in the presence of weeds. I know what you're thinking - The weeds use resources needed by the crop, so the crop 'starves'. Simple. BUT THAT'S NOT IT!

End of feed.
