It seems that nature is trying to bring things into balance
by absorbing the acidic gases CO2, SO3 and NO2 in raindrops
thus bringing them to the earth where they are absorbed by cations in the soil
and sea water.
In Atmospheric Raindrops:
CO2 + H2O ----> H2CO3
SO3 + H2O -----> H2SO3
2 NO2 + H2O ----> HNO3 + HNO2
In Ground Water:
CaCO3 + H2CO3 -----> Ca(HCO3)2
CaCO3 + H2SO3 -----> CaSO3 + H2CO3aq
H2CO3aq + CaCO3 -----> Ca(HCO3)2
CaCO3 + HNO3 + HNO2 -----> Ca(NO3-NO2) + H2CO3
H2CO3aq + CaCO3 ----> Ca(HCO3)2
Also, "Depletion" of the Ozone Layer allows lower level
oxidation of Methane to CO2 + H2O where it can be scrubbed by the same
process.
