This reminds me of a few years ago, when I was doing some piece about the ozone layer and the history of the science.
So when we do things that emit GHGs, we also likely emit local pollution that kills, & becomes regional acid rain (destroying lakes, crops & forests), & acidifies the ocean, depletes the ozone layer (some pollutants), and maybe a hundre other harms, in addition to contributing to GW, and to runaway GW.
I remembered when I was young, we were taught that glass building panels would «kill the earth», it was then, when there were fewer building of glass window surrounds the building, but now, everywhere — most buildings are geering up for the tallest in the region and of course thinning up the ozone layer.

When life on Earth ends, however, no one will know what caused it — the cause could have been ANY of the MANY environmental threats we were told were going to end life on Earth as we knew it, starting in the 1960s with DDT... then other pesticides, acid rain, hole in the ozone layer, global warming, global cooling, climate change, etc..
When scientists discovered a huge and growing hole in the earth's ozone layer, Canadian researchers and bureaucrats were so central to the response that the ensuing global ban in the manufacture of ozone - depleting chemicals would be named the Montreal Protocol.
Since the 1980s the most severe ozone layer depletion has been regularly observed over Antarctica during spring, when ozone levels drop by over 95 % and UV radiation reaching Earth's surface increases substantially.
As many of you will know, and perhaps recall from living memory, alarm bells started ringing when pioneering research by a group of brilliant chemists (Frank Sherwood Rowland, Mario Molina and Paul Crutzen, who were jointly awarded the Nobel Prize for Chemistry in 1995) showed that chlorofluorocarbons (CFCs), a family of chemicals used in many everyday applications such as refrigeration, air conditioning and aerosols, were destroying the ozone molecules which make up the protective layer shielding Earth from the sun's harmful rays.
Here is how the more active sun would deplete ozone in the higher layers so as to cool them and thereby accelerate the upward energy flux from the stratosphere below which then cools instead of warming when the sun is more active:
Three British scientists shocked the world when they revealed on May 16th, 1985 — 25 years ago — that aerosol chemicals, among other factors, had torn a hole in the ozone layer over the South Pole.
Anyway, because the models assume the atmosphere is only in local energy equilibrium, they conclude that when the ozone absorbs the ultraviolet light, it heats up the air in the ozone layer.
