Besides the fact that PH is a measurement of hydrogen ions. How many hydrogen ions in co2?
BTW I live surrounded by automotive factories. My rainwater is 7.0. A side effect of clean air. I grow blueberries and have to add acid even to my rainwater.
I use rainwater to test soil PH as it is neutral.

Yes, pH is a measure of hydronium ions. CO2 becomes carbonic acid in water. CO2 is higher in the atmosphere such that the ocean is 30-40% more acidic than it was 100 years ago. Rainwater is not neutral, it's almost always acidic due to the lack of buffering capacity as stated above.
None of this is political, it's fact. Scientific fact.
