As to the 35km question: If you travel high enough in our atmosphere you will reach a similar pressure.
Air temperature and surface temperatures are effected by radiant heat transfer. There is a good representation of this by a Scientist by the name of Trenberth (I think it was) who quantified the Earth's energy balance. I will see if I can find a link later.

Radiant heat is probably whats going on, I would guess, the equator being in direct sunlight rather than being tangentially exposed like the poles. Perhaps
