This water photolysis must have happened to the primordial Earth, with loss of Hydrogen to space but it was stopped, as it is today, by the presence of ozone (O3) which requires high oxygen tension to form and it quickly reoxidises hydrogen via OH hydroxyls back to water.

Because ozone rapidly decreases with height (very little ozone above 35 km), ozone loss is estimated to have caused only half of the cooling at the higher levels of the stratosphere.

The electron belt is on top of the proton belt, the so called van Allen belts, then there is the upper ionosphere which tends negative and the lower ionosphere that tends positive, and this coupling impact, and space particles attracted to opposing sings and a dance of high energy particles that come with O2 splitting and ozone level increases, namely toward the tropics, while the closing isobars bring particles to the poles... all mean that flaring has a HUGE electrical meaning.

We've changed the atmosphere in other ways, mainly by adding ozone and aerosols at the ground, and destroying ozone high in the atmosphere with CFCs.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

It is also because the ozone hole often extends beyond the Antarctic Circle, which together with its high altitude ensures sunlight reaches regions of depleted ozone long after the pole falls into shadow at the surface.
