"...and assuming that the Earth wasn't closer to the Sun 65 million years ago. ;')"
But would it have been more hot on this planet if it was closer to the Sun? What if the atmosphere was 'different'?
I think I see what you mean though...Earth did 'sink beneath its wonted place' by 'two hand's breadth' and that must have been quite a distance. (And that wasn't 65 million years ago!)
