A Small Double Ozone Hole

Edufer said:
It seems that the ozone hole scare is still in good health. They keep passing subtle missinformation (or shameless lies) as <i>"Ozone is vulnerable, though, to CFCs and halons being released into the atmosphere."</i>, without letting know the gullible people that CFCs and halocarbons are <B>INERT</B>, so they can't react with ozone. In any case, the ozone <B>MIGHT</B> react with chlorine, but <b>ONLY</b> on the surface of ice crystals in stratospheric polar clouds (SPC) over Antarctica, as demonstrated (back in 1988) by S. Salomon, R. Stolarski, et al, one of the teams trying to prove the dangers of CFCs to our stratosphere. (published in Science, 1988. I will give you the reference in a next post, if you are interested, maybe quoting the main conclusions of the paper.)

But the scare and the hoax must be mantained in working conditions, because the amount of money involved is huge. Presently, the production of CFCs is <b>well and alive</b>, esoecially in China and India (besides France and other western countries) and the black market created by the CFC ban is greater than the weapons trafficking, lagging not too far behind the narcotraffic business. Money talks ... and the fools listen. ;) :D
This reply is bullshit. The hole in the layer of ozone around the Antarctic - as is clearly shown on the map - clearly and succulently shows and explains why there has been such a dramatic increase in skin cancer in Argentina and Chile. And we, in the scientific community, have known this for the last decade. I suppose Edufer also believes that Global Warming is a "hoax"?

I do not have time to read all the subsequent posts today but will respond this weekend.
 
Actually, all I can find says that melanomas are caused by both UV A and B. Just different kinds of melanomas are formed.

Key quote from the last link:
At one time scientists believed that only UVB rays played a role in the formation of skin cancer. And UVB light does cause harmful changes in skin cell DNA, including the development of oncogenes — a type of gene that can turn a normal cell into a malignant one. UVB rays are responsible for sunburn and for many basal cell and squamous cell cancers. But UVA also contributes to skin cancer. It penetrates the skin more deeply than UVB does, weakens the skin's immune system and increases the risk of cancer, especially melanoma.
