Yes for colder planets warming harder
Yes for futuristic resolutions
Global warming is implemented very poorly in terms of realism in Civ4 (sure, there should be a negative effect after blowing a nuke, but in real life what ensues is global cooling, due to the amount of dust created blocking out the sunlight!)
In terms of actual global warming (due to gases), the consequences should be incremental, with a warming indicator somewhere, showing the change in °C or °F. My proposal is that:
-When global warming starts, there should be a warning;
-At ~2°C change, some coastal terrains would get flooded; spreading of the deserts (desertification) would start, that would firstly arise near the equator, then it would spread out
-At ~4°C change, all plots produce 1 less food point, cities near the coast might get flooded and are evacuated-people die but the city and buildings stay (so when the temperature and water drops, one could repopulate them);
-At ~8°C change, snow at high latitudes might thaw enough to start changing into tundra and grassland
The warming should start only when there is too much people living with electrical power from coal or oil, and depend on the amount of forests, i. e. one forest tile compensating for 5 million people, a jungle tile-maybe 10 or 15 million (finally the jungle would be useful for something other then making your citizens unhealthy!). Another thing is to be able to plant forests/jungles by workers late in the game.
