Sir Golum:
You know, I heard an intriuging theory, a while back, that said that the suns changes in temperature could be the cause of ice ages, heat ages (thats what I call global warming). Its only a couple of degree's kelvin, but apparantly that makes an impact on our planet. I think this is the best theory.
You also realize that the Earth's axis of rotation shifts over time too, right? It goes from / to \ and then back to / and so forth. Most scientists think this is a large factor.
