>That means that CO2 is .00038 of the atmosphere, or 380 parts per million. Without citing references, (excuse me please) I seem to remember that it might have recently climbed to ~420 ppm.>

Good question. In case of water, your drinking water pH variation depending on where you are, could be between 6.5 and 8.5, that is basically two orders of magnitude in concentration and no one will know the difference. Of course, you can tolerate pH from 3-4 (vinegar)to 9 to alkaline materials.

Now the sensitivity to concentration may be different in air. And maybe the increase in concentration may just result in 2 degree C difference in temperature which is the error in your home air conditioner. However, 2 degree C above zero maybe enough to melt ice at north pole. And that may matter because the boundary conditions now change in terms of light reflection and absorption.
