It seems quite likely to me (approaching undeniable) that like the O2 portion of our atmosphere, the ozone layer is also a product of the biosphere. This suggests to me that there may have been species of phytoplankton more adapted to UV exposure. At the very least, there may have been species of phytoplankton more adapted to warmer climates. Perhaps the recent (or current) ice age is why phytoplankton seem to prefer colder climates at this time.

Apparently 175 million years ago the CO2 levels began to decline from 2500 ppm down to the 225 ppm average that we have had over the last million years or so (now 400 pmm at the moment). Most of that time the average global temperature was much much higher. If phytoplankton was reason for this change in CO2 levels then it seems likely it was adapted to a higher temperature. In this case, it would be just a matter of time for these previous versions of phytoplankton to reassert themselves, though the evolutionary time scale is not so helpful to human civilization. But then there is Braininvat's suggestion that we might help this along ourselves.

I acknowledge that this is not the only possible explanation. Just because phytoplankton is responsible for the majority of our CO2 to O2 conversion right now does not mean that it always has been. Also the buildup of our current O2 versus CO2 levels may been a rather slow process from other plants or a less effective phytoplankon and we cannot assume it was more effective at higher temperatures in the past.

Whittling away at our carbon footprint. The question is, do these little victories aid the whittling to where it can eventually make a dent?

Nah! Too late. And anyway, the current US administration will do more harm in a year than the rest of world can undo in a decade.

More admirable whittling.

Had we begun these measures in 1968
1967 - Manabe and Wetherald make a convincing calculation that doubling CO2 would raise world temperatures a couple of degrees. =>Radiation math
1968
Studies suggest a possibility of collapse of Antarctic ice sheets, which would raise sea levels catastrophically. =>Sea rise & ice

the whole thing might have been prevented - with the bonus of far better health, both of humans and other species, world-wide. Imagine the shape we'd be in if we'd listened back in the 1890's.

The timeline in the link may be of interest.

I don't know where you are, and it doesn't seem to matter. This paper was brought to my attention recently. I mentioned it elsewhere, but if you're still interested, here it is again
