The discovery of the Antarctic ozone hole did prove that CFCs have an effect on our atmosphere. However, many also believe that CREs play a part, too.

The Antarctic ozone hole is shown here, as it was measured on October 7, 2021. Also visible on the map are thin regions of the ozone layer farther north, in the mid-latitudes. (NOAA Climate.gov) ...

The difference is actually quite slight – the ozone layer features the triple-atom oxygen molecule at a level of 10 parts per million (ppm), versus the level of 0.3 ppm seen on average in the ...

In the 1970s and 80s, a series of pioneering experiments showed that CFCs were destroying ozone in the earth’s stratosphere and, in particular, creating a gaping hole in the layer above Antarctica.

Earth’s protective ozone layer is finally healing from damage caused by aerosol sprays and coolants, a new United Nations report said. The ozone layer had been thinning since the late 1970s.

CFCs didn't just eat the ozone layer, they were also powerful greenhouse gases, and by eliminating them, we've avoided significant climate warming.

This study upends how we think about the ozone layer and our health The ozone layer’s effect on our lives may be more complicated than it seems September 22, 2023 7 min ...

One of the significant milestones occurred on Jan. 1, 1989 when a treaty called the Montreal Protocol on Substances that Deplete the Ozone Layer came into effect.

At its worst in the late 1990s, about 10 per cent of the upper ozone layer was depleted, said Newman. Since 2000, it has increased by about 1 to 3 per cent per decade, the report said.
