Hi everyone. I have a number of questions of a scientific nature that I don't consider myself learned enough to answer. These are not for homework, but purely my own interest. As I am so far unable find the answers in the great Googleverse, I've come here. Unlike most of you I'm neither educated, nor posess any depth of knowledge, in any of the subjects here; they merely interest me is all. I hope you'll be kind enough to bear with me in all my layperson-ness lol.
My question is, as in the subject, what if Earth never experienced any glacial age?
1. How would this have happened? (Would something prevent the glacial age from happening? Would there be factors lacking so that it didn't happen? Or would the cause be something else entirely, such as Sun cycles?)
2. What would be the effect to life on Earth today? How would the absence of such glacial ages affect evolution of life on Earth?
I appreciate this is a very complex question and I may be approaching it from enitrely the wrong angle (perhaps I should first be asking what caused the glacial ages?), but if it's possible to answer - or at least hypothesize - it from this angle I thought I'd give it a go.
Thanks in advance to anyone who can help!
