By the way: if you think the ozone hole was other than an imminent catastrophe, you utterly failed to understand it. It took herculean effort by thousands of people around the world, from diplomats to chemists, to avert that catastrophe. They mostly succeeded.

You seem to be in the position of the guy who insists Y2K was a big nothing because nothing happened. But it turned out that way precisely because $billions were spent to bring that about.

Your house stays warm in winter not because the cold is no problem, but because you have an active system ensuring, at substantial cost, that the temperature stays up.

Consider yourself schooled, and let the realization percolate.

It turns out now that their remedy, HFCs, also have ~2500x GHG heat forcing potential over CO2. Fluorine compounds already released account for 10% of heat forcing beyond natural level. The implication is that even if we were to remove all the added CO2, we still could not get back to the preindustrial condition.

There is a very large effort going on as I write this to phase out HFCs and substitute a new refrigerant less harmful if released. Big industrial refrigeration systems have returned to using ammonia refrigerant as a way to avoid involvement in another big rollout.
