Global warming and the hole in the ozone layer?
Answer:
They're mostly separate, but related in some minor ways.
CFCs which cause the hole are a greenhouse gas, though only a minor one.
Warming causes the hole to be a little larger, in a complicated way.
BTW, it's pretty funny how skeptics keep bringing up the fact that historically CO2 lagged temperature, because it's one of the proofs that this warming is not natural.
CO2 can act in two ways (this is very basic science). It can cause warming through the greenhouse effect, and it is released by warming, since warm ocean waters can hold less CO2.
Historically, warming happened for other reasons, usually the Sun, and then CO2 rose hundreds of years later as the ocean warmed. This time CO2 is going up simultaneously with temperature, proving that this warming is caused by CO2 from burning fossil fuels.

Not connected. Global Warming deals with temperatures rising, and ozone is just UV rays.
What contributes to global warming and ozone depletion? Harmful chemicals and the burning of fossil fuels. Both of which are more or less gases that get released into the atmosphere. So in a way yes, they would be connected.
Think about the greenhouse effect and how gases become trapped in the atmosphere thus warming it and the globe. Now in those gases are CFC's and other ozone-depleting substances. If a ton of them gather at a specific location (such as the poles) then they could very well cause a hole in the ozone layer.
That's my take on it, but I'm not a scientist and could be wrong.
No. They are unrelated phenomenae. Ozone depeetion is caused by the presence of CFCs--chemicals that break down the ozone. They don't occur naturally, but are produced by man. The current global warming is caused by excessive amounts of CO2 being added to the atmosphere , largely by the burning of fossil fuels.
BTW--current evidence shows that the worldwide restrictions on CFCs are working--although it will still be several decades before ozone levels return to normal.
The ice-core data is frequently cited as principal evidence to argue that CO2 is the earth’s main climate driver. Rises in the CO2 level "closely corellate" to rises in temperature. It is the jewel in the crown of the theory of man made global warming. But the ice-core data does not show that CO2 drives climate. It shows, very clearly, that the opposite is true!! Variations in temperature precede rises in atmospheric CO2 by several hundred years. It's true they correllate, but with an inverse relationship to that inferred by the Global Warming quacks.
Talk about an inconvenient truth.

good Question,,,,,,,,I,,,think,,,,,... warming i related to the raise in temperature, whereas the ozone layer depletion is related to the monoxides and chlorine (chlorides), if am i wrong pls forgive,,
Bob is correct that global warming and the ozone layer hole are very minimally related scientifically. However, in terms of political policy they're rather similar.
Once scientists realized the hole in the ozone layer was becoming a big problem, there was an international conference in Montreal in 1987. All the government representatives who met there signed the Montreal Protocol, which was an agreement to phase out chlorofluorocarbons (CFCs), the particles causing the hole in the ozone layer. By 1996 the countries weren't producing CFCs anymore, and since then the hole in the ozone layer has almost stopped growing. It hasn't quite stopped yet because the lifetime of CFCs in the atmosphere is 50-100 years, and some developing countries which didn't participate in the Montreal Protocol still use them.
The analogy to global warming is of course the Kyoto Protocol. Scientists realized that human-caused global warming is becoming a major problem, and government representatives met in Kyoto to try and resolve it. The problem is that we're more dependent on fossil fuels than we were on CFCs, so people are more resistant to change. There's also some debate as to how much humans contribute to global warming, and people use this as an excuse not to take action.
So not only did the Kyoto Protocol only propose a very slight solution to the problem (a 5% reduction in greenhouse gas emissions by 2012, which is very minor) while the Montreal Protocol was a much more effective solution, but the US and Australia didn't even agree to sign the Kyoto Protocol.
The hole in the ozone layer and in the minds of thinking fools are connected to a blind spot in the cerebellum. Global warming stands alone on its own merits and the merits of the Aboriginal peoples of the world.
