Does air thin out at northern latitudes?

An AP story titled 4 presumed dead after avalanche on Mount McKinley includes the text:

Mount McKinley, also known as Denali, is North America's tallest peak. While not a particularly tall peak by global standards, its latitude makes for far thinner air than is found in mountains closer to the equator. That, combined with the weather and temperatures, makes it a particularly dangerous climb.
