Ozone Hole Natural
Timothy Birdnow
They told us it was because of CFC's and we stopped using them. Now we can see it was natural, but we are now supposed to forget that fact and accept the climate hysteria of carbon dioxide as gospel. It wears thin after a while.

But why is the ozone layer destroyed every year? If we want to
destroy ozone and create and grow the ozone hole, we need two main
ingredients: cold temperatures and sunlight. Cold temperature enables
the stratospheric clouds to form. As long as it remains dark, nothing
happens with these clouds.
When south polar spring arrives (Aug-Sept), UV radiation from the Sun reaches the Antarctic Circle and reacts with the stratospheric clouds. It starts a photochemical reaction of chlorine release and thus destroying the ozone in the process.
The theoretical threshold for stratospheric clouds to form is below -78°C (-108.4°F). The image below from NASA shows the minimum temperatures over the wide Antarctic circle at 50mb level (~19km altitude). The current minimum temperature is still at the threshold for polar stratospheric clouds (PSC) to form. That means it is cold enough to sustain the ozone destruction process.
