What is it about?
The globe has warmed more than one degree Centigrade since 1970 and some of this warming appears to have been caused by humans, but greenhouse-warming theory has never been demonstrated by experiment to actually cause global warming. Manufactured chlorofluorocarbon gases (CFCs) and chlorine and bromine emitted during volcanic eruptions are observed to deplete the ozone layer. The ozone layer normally absorbs most ultraviolet-B solar radiation protecting life on Earth from this very “hot”, sunburning, skin-cancer-causing radiation. When ozone is depleted, more ultraviolet-B radiation is observed to reach Earth, cooling the ozone layer and warming Earth. Ozone depletion theory provides a more direct, more detailed, and more precise explanation for global warming observed in the past 100 years and throughout Earth history than greenhouse-warming theory.

Why is it important?
On 12 December 2015, 195 countries agreed in Paris to reduce greenhouse-gas emissions in order to hold “the increase in the global average temperature to well below 2 °C above pre-industrial levels” at a cost thought to exceed ten trillion dollars. This is likely to be a waste of money. It is extremely important that we understand clearly what has caused observed global warming.
Perspectives
In 2006, I discovered that the greatest volcanism recorded within Greenland ice was contemporaneous with the greatest warming as the world warmed out of the last ice age from 12,000 to 9,000 years ago. This did not make sense because major explosive volcanic eruptions throughout recorded history have typically caused 0.5 degrees Centigrade global cooling for 2 to 4 years. I have worked full-time since then trying to understand a wealth of data that show clearly that ozone depletion is far more important to climate change than greenhouse gases.
