Eh. I think some section of China might endure. The mega-metropolitan areas of the south are megascrewed, but the mountains and more harsh climates of the north and west provides some interesting opportunities.
I guess I was being harsh and overgeneralizing, I was focusing more on the urban areas. That is true, it can get very, very cold in northern China, or so I hear. And in remote places like those, I agree, I think they'd have a fighting chance. I do think, though, that unless you happen to already be there, you're not going to have too much of a chance. I dunno, I just can't see too many people in any major cities making it out in time.
What I think is the most interesting is the bomb shelters of America. There are people who actually keep and maintain shelters just in case everything goes up in flames, they probably have enough food to last through a nuclear winter and weapons to boot. Granted some of them would have probably been destroyed either through internal strife or infected people or animals sneaking in. But it is a possibility there are small communities in the U.S. that are still making by.
You know, I hadn't really thought of bomb shelters. I'm sure there are plenty left over from the Cold War, and I'm even more sure that there are no shortage of survivalists that maintain their own. A lot of people own large, remote plots of land for hunting and stuff, too. Provided they were able to get set up properly, one could live relatively comfortably. It honestly does get pretty cold up here, too, especially in places like Vermont. Going by a quick look at Wikipedia, it gets a little colder on average in Burlington, Vermont than it does in Mora, Sweden (totally feel free to check me on that, I might just be missing something).
