I’d love to see the explanation for what happened with temperature and humidity variations here

I'll dig through the data more when all runs are done, but it's mostly down to slower rotation causing weaker coriolis forces and thus allowing for a wider Hadley cell, thus more efficiently transporting heat from tropics to poles in the upper atmosphere and transporting moisture towards the tropics in the lower atmosphere. I suspect that this is also causing more cloud cover over the tropics, increasing the albedo and so both cooling the tropics locally and the planet as a whole.

Speaking of long rotation times...what about long orbit times? Have you given thought on how to adapt your climate script for worlds with long years? I think worlds around high-mass stars (with corresponding long orbits) don't get enough love, so they are a focus of my simulations. How might the climate classification schema be adapted to a world with a 2-4 (or more) year orbit? If the planet has significant obliquity or eccentricity there would be "seasons" that lasted for years. I'm familiar with python so I'd be happy to try creating a long-orbit climate version of the script should you have any ideas.

Year length is a single parameter in the input scripts, but of course it's not independent of other values like star temperature and stellar flux. After the experiments with day length (and maybe eccentricity if the exoplasim updates come soon) I've already queued up a set of models with Earth shifted to different points of the sun's habitable zone (though exoplasim isn't great for the outer hab zone with high CO2 levels) and a set with appropriate values for planets in a roughly equivalent spot in the inner habitable zone of m- to a-type stars.
