I had a global warming in 2008. As I got several saves (for 2007, 2008, 2006...), I could move back some tim - is there anything I can do to avoid this warming? I know all this Mass Transport/Recycling center/Solar Plant etc. But I got all of this stuff, and for 115 cities I got 21 Solar Plants now (5 more under construction). There was a nuclear war anyhow some time ago and there are still 5 cities surrounded by pollution. I am cleaning it with 5 engineers (1 more each turn), but maybe that's too slow? And still I got like 10 cities to conquer - whenever I capture a city, there is an enormous amount of pollution. I need to buy mass transport immediately ($640), but it gets built only after it pollutes everything for 1 turn.... I tried to start again in 2006, bought 3 solar plants close to those polluted cities but in 2008 there was again a global warming... Anything to do, or this battle is just lost...?
