Chloroflourocarbons were first created in 1928 and first marketted in the 1930's. They grew in popularity as non-toxic refrigerants, so about by 1988 consumption was a billion kg a year. Stratospheric ozone levels have been measured since 1956. In 1974 M.J.Molina and F.S.Rowland published a paper indicating that ozone and the chlorine from CFCs could interact to destroy the ozone if UV light was present. In May of 1985 Farman, Gardinar and Shanklin. published a report in Nature showing that ozone levels had dropped to 10% below normal January levels for Antarctica. Reworking old data indicated that there was evidence for the global ozone depletion as far back as 1976. In 1989 Anderson, J.G., W.H. Brune, M.H. Proffett, published in the Journal of Geophysical Research that ClO had been detected in the atmosphere, showing that CFCs were contributing to ozone depletion.
The ozone layer was discovered in 1913 by the french physicists Charles Fabry and Henri Buisson.
See "When was ozone and the ozone layer and ozone depletion and the ozone hole discovered?"
Mario Molina was the first. He said that CFC's cause ozone depletion.
The scientist that discovered was Dr. Joe Farman. He had this discovery.
CFC's gases contain Chlorine and Fluorine. They react with ozone to deplete it.

Ozone depletion occurs in the?
Ozone depletion occurs in the ozone layer.
What can lead to the depletion of the ozone layer of earth?
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
Is the depletion of the ozone layer nature friendly?
No it is not nature friendly. Depletion of ozone layer is harmful.
Who discovers that the ozone layer was already damage?
Dr Joseph Farman discovered Ozone depletion. He noticed it over Antarctica.
What is oh use of the depletion of ozone layer?
Depletion of ozone layer only brings bad to environment. UV enters and thus causes depletion to ozone.
Definition of depletion of ozone layer?
Ozone layer depletion can be defined as destruction of ozone. This ozone is the ozone layer.
Ozone depletion occurs in the?
Ozone depletion occurs in the ozone layer.
What can lead to the depletion of the ozone layer of earth?
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
What is meant by ozone layer depletion?
The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.
When was ozone and the ozone layer and ozone depletion and the ozone hole discovered?
OzoneOzone was discovered by by Christian Friedrich Schönbein in 1839 - 1840The ozone layer was discovered by Charles Fabry and Henri Buisson in 1913.Depletion of the ozone layer was identified by the US Academy of Sciences in 1976 as being in agreement with the available data.The ozone hole was discovered by Joseph Farman (team leader), Brian Gardiner, and Jonathan Shanklin in 1984 (reported in 1985).See links below.The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson.
Whae is ozone layer depletion?
Ozone layer depletion is the thinning of ozone layer. It is most evident over the poles on earth.
When the depletion of the ozone layer started?
The depletion of ozone layer started with the advent of CFC's. They react with ozone and destroy it.
Is ozone layer the same as ozone depletion?
No ozone layer and ozone depletion are different terms. Actually they are quiet the opposite terms.
What is definition of Ozone layer depletion?
Ozone depletion is the depletion of ozone molecules. It is happening because of CFC's.
Is the depletion of the ozone layer nature friendly?
No it is not nature friendly. Depletion of ozone layer is harmful.
Who discovers that the ozone layer was already damage?
Dr Joseph Farman discovered Ozone depletion. He noticed it over Antarctica.
Causes for ozone layer depletion?
Ozone depletion is caused by CFC's.
