Flap:
The problem is that all of those happen on geologic time scales, and we can't readily observe alot of these changes.
Axis/orbit length/orbit ecentricity are all part of the Milankovich cycle; which have periods of 23K yrs, 41K yrs, 100/400k yrs...
ice ages (glacial/interglacial) is generally on the order of 100k... i.e the last glacial max was ~20K BP, before that there was a long warm period ~75K yrs...
All of these are longer time scales than greenhouse gases, increased heat absorbtion (all that black-top) etc....
But you're right... there is change going on constantly.... most people dont appreciate it or grasp it....
