It is expected to take decades for the gases we have already released to leave the upper atmosphere. And third world countries are still making, using, and selling them. It will be a while before we know. Last year's (2008) ozone hole was not record sized, but it was very close to record sized.

∙ 14y agoShort Answer: The *hope* is that there will eventually be a significant decrease in UV-B transmitted through to Earth's surface, off the equator where most people live. CFC can (so far) only be permanently be removed by energetic UV, which is found in-and-above the ozone layer. Once we stop adding these (and similar) compounds to the atmosphere, they will eventually degrade and stop whatever contribution they are making to ozone depletion. One symptom of improvement should be a somewhat smaller ozone "hole" (on average), one that appears later, and one that "heals" sooner. Reduction in UV-B means fewer cataracts, less melanoma, fewer mutations, increased crop yields (all other things being equal), and gain of arable lands that may have been lost. If we hold our tongue just right...

Do chlorofluorocarbons have a negative effect on the ozone layer?
Yes, chlorofluorocarbons have an adverse effect on the ozone layer. These react with ozone and decompose it to deplete the ozone layer.
How can chlorofluorocarbon affect your ozone layer?
Chlorofluorocarbons or CFC's are a vast effect on ozone layer. They chemically react with them to deplete them.
Which chemical damages the protective ozone layer?
Chlorofluorocarbons damage the protective ozone layer.
Did banning aerosol cans reduce carbon dioxide emissions?
No. Banning CFCs (chlorofluorocarbons) that powered some spray cans stopped the destruction of the ozone layer. The ozone layer, which protects us from dangerous UV radiation, is expected to recover by around 2050 if nothing else attacks it.
What is the effect of humans adding chlorofluorocarbons to the ozone layer?
Humans are using CFC's is many things like AC's, deodorants etc. This is causing the depletion in the layer of ozone.
Do chlorofluorocarbons have a negative effect on the ozone layer?
Yes, chlorofluorocarbons have an adverse effect on the ozone layer. These react with ozone and decompose it to deplete the ozone layer.
What do scientists predict the banning of the use of chlorofluorocarbons will do?
Banning the use of chlorofluorocarbons has begun to allow the ozone layer to recover. this improvement is predicted to continue.
How can chlorofluorocarbon affect your ozone layer?
Chlorofluorocarbons or CFC's are a vast effect on ozone layer. They chemically react with them to deplete them.
What are chlorofluorocarbons and how do they effect the ozone layer?
CFC's are man made chemicals. They react with ozone and deplete it.
Which chemical damages the protective ozone layer?
Chlorofluorocarbons damage the protective ozone layer.
What effect the refrigerant on environmental?
Some refrigerants have chlorofluorocarbons that are harmful to the ozone layer. The CFCs can lead to rapid depletion of the ozone layer in the atmosphere.
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
What are chlorofluorocarbons doing ti the ozone layer and how?
They are depleting the ozone layer. they react with ozone and deplete it.
What can destroy the ozone?
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.
Did banning aerosol cans reduce carbon dioxide emissions?
No. Banning CFCs (chlorofluorocarbons) that powered some spray cans stopped the destruction of the ozone layer. The ozone layer, which protects us from dangerous UV radiation, is expected to recover by around 2050 if nothing else attacks it.
What is the effect of humans adding chlorofluorocarbons to the ozone layer?
Humans are using CFC's is many things like AC's, deodorants etc. This is causing the depletion in the layer of ozone.
How are the chlorofluorcarbons harming the ozone layer?
The Chlorofluorocarbons are harming the ozone layer. They decompose into halogens which destroy ozone.
