Comment on CFCs

Today, the ozone hole still exists, forming every year over Antarctica in the spring. It closes up again over the summer as stratospheric air from lower latitudes is mixed in, patching it up until the following spring when the cycle begins again. But there’s evidence it’s starting to disappear – and recover more or less as expected, says Solomon. Based on scientific assessments, the ozone layer is expected to return to pre-1980 levels around the middle of the century. Healing is slow because of the long lifespan of ozone-depleting molecules. Some persist in the atmosphere for 50 to 150 years before decaying.

It’s not. I’m guessing they did a Google search, looked at a few misleading article titles, and then decided they were a scientist.
On average, the hole has been shrinking, but 2023’s hole was the 12th biggest on record. The eruption of Hunga-Tonga was thought to be the main factor.
