Don't forget that CO2 is heavier than O2, [1]. So if we don't keep that wind going, all the CO2 will sink to the bottom of the atmosphere, pushing the O2 up. I'm not sure if that is a linear process (x percent less wind meaning x percent less oxygen).

You mean CO2 would concentrate at tree level to be more easily absorbed and converted back into oxygen, rather than in the upper atmosphere where it heats the earth? I'm not sure I see the downside.

Even in "still" air, the individual molecules have random velocities due to temperature - on the order of 100 m/s. Combined with the fact that there are more mixed configurations than unmixed configurations (entropy of mixing), this randomness effectively stirs the atmosphere without the need for the bulk motion of the wind.

Don't worry about pushing up O2 all them airliners will suck it up.
