What's At Stake Anyway ??

Global warming , political and scientific debate's Big buisness being the biggest contributers and... the detractor's of truth.... But...i have another question........ is it possible , at one time , the earth and the sun were at it's greatest distance apart hence , the Ice Age........ Do you think it's now possible , the earth and sun are now coming closer to eachother ?? when we consider " time " as we know it , universal time isn't exactly the same..... Who within' our lifetime or... generation's past , have had the knowledge or even the patience to track all this anyway ?? Sure hope we did'nt burn information at the STAKE !!
