I'm not sure if this is a geology question - but perhaps someone can answer it anyway. Is there any way of explaining why the earth is flattened at each pole? And what effects does this have on climate, or any other aspect of earthly conditions?
TheBox is absolutely correct.I will add: If we ignore the little bit of roughness that is geography (mountains, valleys etc.) the earth is essentially "flat" everywhere. This is a reasonable assumption--if the earth were the size of a marble, it would be smoother than the smoothest marble in existence. A marble will sit still on any flat surface that you place it on, no matter which point is on the bottom, because it is "flat" at every point. The same applies to the Earth.Now, as TheBox pointed out, the Earth is spinning and therefore is every-so-slightly distorted such that it is wider across the equator than it is from pole to pole.This distortion of shape of the Earth doesn't really have much effect on the climate that I know of. But the spinning that causes the distortion is also responsible for the Coriolis effect, which has some effects on the weather (not on the climate though, as far as I know) (https://en.wikipedia.org/wiki/Coriolis_force#Meteorology)

the Earth not seemingly having two points of external force/pressure applied, the work done apparently internally.
