#physics #weather **Two types of computer modelling** One, favoured by the influencers uses no physics, and is a pattern extrapolation. To get the last warm cycle, they had to input a 'temperature riser' to match the, then current, rising temps. The other type is 'game physics' or modelling using first principles. I prefer the latter, but there is no funding to get it right. I read a paper that did prime ocean modelling. They said that every hot and cold cycle in the past could be explained by ocean currents, but they didn't run the current cycle because that was obviously carbon I hope they survived.
