Vox - A new UN report finds that the Earth's protective ozone layer is finally starting to recover — after efforts in the 1980s to phase out CFCs and other destructive chemicals.
Back in the 1970s, scientists first realized that we were rapidly depleting Earth's stratospheric ozone layer, which protects us from the sun's harmful ultraviolet rays.
The culprit? Chlorofluorocarbons — chemicals that were widely used in refrigerators and air conditioners. These chemicals had already chewed a massive "hole" in the ozone layer above Antarctica, and the damage was poised to spread further north.
Without the ozone layer's protection, more and more people would be exposed to UV rays. Skin-cancer rates in many places might have soared, as they already have in Puentas Arenas, Chile, which lies under the existing ozone hole. Those UV rays could also harm crops and the marine food chain.

There was never anything wrong with the ozone layer. it was an invented crisis - a trial run for the AGW scam.
