The balance of ozone and sun
3 Ozone depletion levels
The 3 levels of global stratospheric ozone depletion are clearly visible in the global temperature showing a connection between the two. There are seasonal and solar variations in temperature that are depend on the altitude of the stratosphere and the latitude.

The balance of ozone and sun
The ozone layer is our most important defence against the suns powerful radiation that heats the planet. It is a fragile molecule and is easily bullied around by other chemical reactions and electrical fluctuations in the atmosphere.The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50 km above earths surface. It is created by the suns UV radiation and destroyed by the reaction with atomic oxygen:
O3 + O → 2 O2
The latter reaction is catalysed by the presence of certain free radicals, of which the most important are hydroxyl (OH), nitric oxide (NO) and atomic chlorine (Cl) and bromine (Br). In recent decades the amount of ozone in the stratosphere has been declining due to three major factors. One is the emissions of CFCs and similar chlorinated and brominated organic molecules, which have increased the concentration of ozone-depleting catalysts above the natural background. The other two come in the form of particle showers that flow from the blanket of electricity that surrounds the planet called the ionosphere and the blanket of gravity called the magnetosphere. Protons come from the sun in what are known as solar proton events and can slash ozone levels derastically while the electrons come from PLHR (Power Line Harmonic Radiation) interacting with the magnetosphere and broadcast radiation from the radio, television, and telecom industry reacts with the ionosphere. This particle precipitation reacts with the chemicals in the upper atmosphere and form NO2 and OH which are carried down to the lower atmosphere by what is called the polar vortex.
Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total amount of ozone in Earth's stratosphere since around 1980; and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole. As the ozone layer becomes thinner it blocks less and less of the solar radiation allowing the solar energy to heat the ocean water causing it to evaporate into the atmosphere. The increase in water vapor then acts as a greenhouse gass. Water vapor is the most abundant of all the greenhouse gasses in the the global greenhouse effect. The polar ice caps have been melting below the ozone holes and although scientists observe the ocean levels rise around the globe, since the 70's Arctic ocean levels have actually been dropping due to evaporation and salinity.
