Started from a post about the Mars Ice Caps and went from there. Spent a lot of time diving into things, and learned quite a bit. Backed off a 'remark' I planned to make on the original article. It would have been wrong, very wrong.
The second half of this was about 'climate modelling' (on Earth), and a couple of 20 year old conclusions/observations that I had never been able to verify. Got that answered, in spades. Satisfying.
It's a long digression, a lot of back and forth - NOT a light read at all. Spent about 2-3 hours on it, soooo thought I would share it, just in case some of ya'll might have an interest.
