[QUOTE="AlexB23, post: 77657372, member: 450900"] Ooh, another interesting tidbit of information about the article you gave me. The scientists who determined that the Earth would stay hot for centuries, even if our emissions went to 0 tons of CO2 today, used advanced computer modeling using a software known as Sky2050 (from the same [URL='https://climate.mit.edu/ask-mit/how-long-will-it-take-temperatures-stop-rising-or-return-normal-if-we-stop-emitting']article[/URL] you posted). :) That would be a fun job to have, cos data analysis and AI is fascinating. For myself, I run a free, private and local AI on my laptop, the Mistral 7B large-language model. I use the local AI to explain Bible verses, win arguments with climate deniers (by summarizing a verse on stewardship), ask it heavy ethics questions, and summarize information when need be. But, running the AI drains my laptop battery in < 4 hours. It is energy intensive. Another thing that is energy intensive is the supercomputing industry. There is something slightly ironic about modeling our warming climate on a mainframe. A supercomputer uses a lot of electricity, so simulating the climate on a supercomputer releases a lot of CO2 also, assuming the supercomputer is connected to a predominantly fossil fuel powered grid. Luckily, the Finnish made a supercomputer that runs on 100% hydroelectricity. Hey, of course, green computing had to be from the Europeans.
