As far as open borders, the pedia calls it Annual, so I didn't know what that was supposed to mean lol. It does seem like 10 turns is about right, although it does seem to scale as well later in the game. I should just remember to take notes, but I never do.
I'm slowly working my way through all the concept articles in the pedia, updating them with HR changes and stuff from BTS that should be there but isn't. Haven't got to that one yet, it's definitely confusing.
The Local Warming is a good addition I was unaware of; I'm not sure I've noticed it's effects just yet as I tend to do everything possible to preserve forests in my civ's lol. Is Platyping's module one of those that gradually decreases resources as they are used over time, along with deteriorating the local environment? I think that is a great component of some of the other mods. I think it would be excellent for there to be penalties for covering your city with mines that both reduce the resource and deteriorate climate over time. And not just suddenly in the modern era but starting right from the beginning in an appropriate way.
Resources do not deplete in HR at this time. It's something I'd intend to add eventually, but I need to be careful how it's done. Much potential for frustration and imbalance. There's already a penalty for building Mines, Workshops, Wells, Offshore Platforms, and Village/Towns - each one increases unhealthiness in nearby cities, which in turn increases dissent and the likelihood of localized climate change.
