But have ph levels dropped because of the 750 giga tonnes of natural CO2 that goes up into the atmosphere every year OR have they dropped because of the 29 giga tonnes man is emitting ever year.
We're not importing CO2 from mars so its part of the Eartly cycle.....
I've already corrected you on this nonsense that you post before but you obviously don't understand the carbon cycle.
I'll try again.

The natural carbon cycle means that naturally

You have not corrected anything because you are mistaken……!
You're argument would hold true if we imported CO2 from an alien planet imo.
If then what you say is true then the current increase in atmospheric CO2 would be synchronised to man’s emissions of atmospheric CO2 and evident in observations.
Since the year 2000 to the year 2010 we have emitted 3 times more atmospheric CO2 from the burning of fossil fuels in one way, shape, form or another i.e. manmade CO2 emissions, from the prior decade the years 1990-2000, manmade emissions have increased threefold.
In a nut shell man’s emissions of atmospheric CO2 in the former decade 2000-2010 have grown exponentially compared to the prior decade 1990-2000.
Yet observations over that time in the annual increase of atmospheric CO2 over all those years for both decades follows a temperature induced increase in the natural atmospheric CO2 cycle with man’s emission playing a minor role.
In other words the Earth has heated up since the little ice age and has vented more CO2 into the atmosphere.
