First of all Jon, the diameter of the earth is very significant for us mere mortals. A change of just 10 degrees can make a big difference to us. And if you think about it, from equator to pole (which is just 12,000 or so miles) there is 100 degree tempreture difference at any given time.
As to your question, the earth does not sit on a vertical axis, it is at a 30 degree lean angle (roughly) meaning that either the top half or bottom half of the sphere is closer to the sun. Only my a few thousand miles, but as highlighted above, This makes a significant difference. Obviously is does not oppererate like a swithch either, which is why we get the other seasons, as out location slowly moves closer or farther away from our heat source.
There is a lot of stuff about this sort of thing on YouTube.

Not quite sure what to do with my early mid-life crisis. Ideas on a post card to P.O.BOX 150...
