The post you are reporting:
I don't like pasting large extracts of text, but it seems necessary here, Philip and Ray, as quite clearly you are both disputing the scientific evidence of facts.
This is a long extract from Wikipedia, which really cannot be considered biased or involved in any form of vested interests:
"While there are natural sources for all of these species, the concentrations of chlorine and bromine have increased markedly in recent years due to the release of large quantities of man-made organohalogen compounds, especially chlorofluorocarbons (CFCs) and bromofluorocarbons.
These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 100,000 ozone molecules. The breakdown of ozone in the stratosphere results in the ozone molecules being unable to absorb ultraviolet radiation.
Consequently, unabsorbed and dangerous ultraviolet-B radiation is able to reach the Earth's surface. Ozone levels over the northern hemisphere have been dropping by 4% per decade. Over approximately 5% of the Earth's surface, around the north and south poles, much larger seasonal declines have been seen, and are described as ozone holes.
In 2009, nitrous oxide (N2O) was the largest ozone-depleting substance emitted through human activities.["
I may add, that emissions from motor vehicles and aeroplanes are in no small way responsible for these chemical processes that destroy the ozone layer, as too are oil refineries.
Philip and Ray, have you actually heard of the melting down of the Arctic ice? They say it could cause London to submerge! Ultraviolet radiation plays no small part in all this.
I can't go on pasting large extracts of text, as there is so much evidence out there, so I wonder if you might do some research to prove to yourselves that your views are completely contradictory to official policies established by numerous governments over recent decades.
