Well, everything goes in cycles. We have known that there will be another ice age for quite a while. There WILL be another ice age, and another after that and another after that. There will be an infinite amount of ice ages as long as everything is constant. However a meitor hitting the earth would effect our weather by the dust in the air, the sun exploding would obviously have an effect, and that will happen, however I think its supposed to be a few billion years. I don't think what this movie is about is the traditional ice age, because an ice age takes thousands of years. This movie probably takes place within a few years, and 10 years is definatley not enough time for an ice age to suddenly occur. Its more of "climatic chaos" than and ice age according to Pop Sci. Anyway, I haven't seen the movie so i don't really know whats going on.
