I know the hole in the ozone later specifically was solved by a unified concerted effort to address the problem that caused it. I didn’t know the details, but I assume leaded gasoline was the same.
I am not presently seeing that kind of deliberate unity on climate change.

The hole is 8.5 million miles^2.
I wouldn’t consider that “solved”.
I will consider the hole to be solved when it is closed—which will be decades still.

I’ll consider “consistent effective progress along a long recovery route” close enough to “solved” for this particular conversation.
We saw a problem, took action, and the situation has improved since we took action.
