Remember the hole in the ozone layer which was to see the end of the world? surprise surprise, it mended itself and now it is not a problem.
The Ozone "hole" has not "mended itself" at all. It has improved to the point where it is at its smallest, but it is still there.
https://www.nasa.gov/feature/goddard/20 ... -discovery
The annual ozone hole reached its peak extent of 6.3 million square miles (16. 4 million square kilometers) on Sept. 8, and then shrank to less than 3.9 million square miles (10 million square kilometers) for the remainder of September and October, according to NASA and NOAA satellite measurements. During years with normal weather conditions, the ozone hole typically grows to a maximum area of about 8 million square miles in late September or early October.
Note that the "hole", even at its smallest, is larger in area than the entire USA (c. 3.8 million square miles).
It will be there for some time to come because even though humans have massively reduced the release of the CFCs that were the cause of the hole, the effects are long lasting because the chemicals involved are long lasting.
It's interesting to note that the CFC issue was relatively easy to solve because there were readily available alternatives to the worst CFCs. Switching to non-CO2 producing energy systems will not be nearly so easy, of course, and so effects will take longer to mitigate.
Perhaps you should stick to preferentially modding the Ferrari forums and avoid the technical discussions.
