Ozone is an elevated state of Oxygen which occurs when being stuck by a photon. Oxygen and much more heavy and abundant Nitrogen) is doing the protecting from UVc. But are apparently less adept at blocking UVb which fits Ozone better.
Ozone is the unstabile molecule that results. O3 quickly wants to be O2 again so it reacts with many things, natural and man made.
"Regular oxygen molecules, known to science-types as O2, are made up of two oxygen atoms stuck together. Solar energy shoots in from space and splits that molecule into two atoms. When one of those stray atoms attaches to a full-fledged O2 molecule, you've got, well, O3, otherwise known as ozone. All that action blocks solar radiation, and keeps it from reaching us."
I guess the scientific concensus is still that O3 levels were lower in 1987 and have come back up.
But UV levels have continued to rise until 2010 is there something else at work here?
