Always wondered about the hole in the ozone layer.
Was there ever a time when there wasn’t one?
How do CFCs not only somehow cross the air circulation between the hemispheres across the equator, but also get launched so high into the stratosphere despite being heavier than air?
“Was there ever a time when there wasn’t one?”
This was debunked decades ago. The ozone hole expands and contracts on its own schedule. The “scientists” discovered it in an expanding phase, and decided something was destroying the ozone.
