Late game suggestions:
I don't know if Global Warming revamp is a priority or not but I have some thoughts. Understanding that the effects of climate change are drastic and unpredictable I still think it is a bit jarring when a random square amongst grassland turns directly into desert. Would it make more sense to have grassland become less productive before turning into desert? Grassland could turn into plains, which could turn into semi-desert, and finally desert. The rate of change and number of affected tiles could be accelerated so that the effects are still drastic without having weird spots of desert. Similarly tundra, moorland and taiga could potentially become slightly more arable, but maybe at a slower rate. Flooding would be cool but barring adding marsh along coasts and rivers I guess changing coastlines is tricky at best.
I have a couple of further ideas on this which are perhaps more ambitious. Desertification could cause adjacent tiles to become more vulnerable to degradation as well. Labourers could be given the job of mitigating climate change effects in the late game. For example, with the discovery of X technology, planting trees or building dikes could become an option which could be used to prevent degradation, desertification and flooding in tiles adjacent to those affected by global warming. The gamble would be that you might have to destroy a valuable improvement to safeguard the tile, but if you don't safeguard the tile there is a chance it becomes totally unusable.
Also, loosely related, my vassal started randomly nuking Natives, I feel like there should be a mechanic for taking the nuclear toys away from your vassals. I pulled their uranium source but they already had a number of Nuclear bombers on hand.
I had other thoughts, but I've forgotten them thankfully.
