Watching Building extreme Alaska on PBS America and there is a peice on climbers scaling the highest peak, Denali.
The narrator stated that one of the problems is the reduced oxygen level at altitude (yes, no problems with that) but then went on to state that the oxygen levels are lower due to the proximity to the North Pole, but a peak of similar height near the equator would not be as bad.
If this is true, I didn't know this. Thinking about it, the atmosphere is squashed slightly with a bulge at the equator, but would this be noticeable for oxygen levels further North?
Yup, it's true. Water does it too - this is what the earth would look like if it stopped spinning:
