The ozone layer and ozone holes are natural phenomena. Ozone is less likely to form where there's less direct sunlight i.e., at the poles. Hence, holes in the ozone layer over the poles. It is unlikely that reduction in CFC's has resulted in reducing the ozone holes athough it is not good to keep polluting the global environment; pollution is another issue entirely. To assume that human action over reduction in CFC's has had a marked effect on the ozone layer is sheer arrogance; many countries (India, China, other far eastern countries) are still using CFC's. So, if these chemicals have had effect in the past, why are they not doing so now?
Global warming is a grossly mis-used term for a phenomenon that humans can do very little about; it is also a case of representation of data. A political move; it allows governments to put more taxes on the public. It also allows researchers to get funding: many universities rely on the current band-wagon of Global Warming to get funding. The greatest effect to global temperature on the earth is the sun; it dictates how much heat the oceans absorb. That great sink of potential heat energy takes thousands of years to release that energy not just a few hundred. During the 1300's, the world temperature was much warmer than now; grapes could be grown in Scotland! we can't do that now and, human activities were certainly not involved in the world's temperature in the 1300's. It is likely that any slight warming of the earth as a whole is to do with the oceans releasing the heat they absorbed 700 hundred years ago.
Data shows that after the Kraktoa volcanic eruption, a massive scarey event, the globe took about 30 years (into the 1920's) to start to recover in terms of coming back up to the temperature before the eruption. Before that was Tambora, an even greater eruption. There's been Mt St Helen's, Pinatubo and a number in the Ring of Fire since then; so, volcanos are a real influence on global temperature.
Finally, the proper data of global temperatures shows carbon dioxide increasing AFTER temperature rise not before i.e, not associated with a causal increase in temperature. Humans are highly unlikely to cause any sort of global phenomena; but, humans are responsible for serious pollution which is a more serious and real threat to human health and & other living things. Governments perhaps don't want to address that side of things as it means attacking their big industry sponsers.
It really gets me that so many people are really scared about the global warming falacy; so many people being tricked and led on. Try finding out a bit of info about the issue; it makes very interesting reading and very annoying reading too when you realise you've been taken for a ride & a patsy. Pat!

In a sense it has been fixed, in that dumping chlorofluorocarbons (the cause) into the air has been banned in most places. For all environmental issues, stopping doing the thing that causes it is the solution.
Unfortunately the ozone hole is not a cause, or even a leading contributor to global warming (it causes a different problem). It was learned recently that the thinner ozone layer stunts the growth of trees and shortens their lifespan. The dwindling number of trees IS a major cause of Global warming, so in that way the ozone issue plays a role.
I know some skeptic will scurry out to Google and say "I found a tall tree, so I have proved you wrong". You have to make your own judgement about things like that.

You missed to cite the area of the article that confirms that there is very much of variability interior the ozone layer, Dana. "Dr Paul Fraser is from CSIRO's Marine and Atmospheric learn branch. He says whilst scientists have faith the hollow is shrinking, its length does variety from 3 hundred and sixty 5 days to 3 hundred and sixty 5 days. "the biggest driving force of the three hundred and sixty 5 days-to-3 hundred and sixty 5 days variability interior the ozone hollow are stratospheric temperatures, and this became an exceedingly heat 3 hundred and sixty 5 days interior the stratosphere," he suggested. "once you have a heat stratosphere, the tactics that wreck ozone alongside side the CFCs (chloro fluoro carbon) are much less valuable, and so which you ultimately finally end up with a extremely small ozone hollow. "So the three hundred and sixty 5 days to 3 hundred and sixty 5 days variability is set by using the temperature adjustments, yet they're superimposed on a protracted-term vogue and we expect of that's on course in the direction of eventual ozone restoration, yet that's going to take a protracted time." He says the actuality that CFCs (ozone depleting ingredients) have been phased out has helped the area." i'm no longer arguing that CFC's impact ozone concentrations. CFC's can wreck very much of ozone for the time of its lifetime. yet, there remains very much of variability in ozone in the time of the three hundred and sixty 5 days. that there is a undeniable quantity of variability isn't the 1st piece of suggestions that individuals tend to submit.

Actually the ozone layer has been showing signs of improvement since the reduction of CFCs. Just goes to show you that things can change with a little effort. It's not all bad news.

Ozone replentishes itself naturally, the "hole" should be repairing itself provided the scientists dont find something else that is destroying the Ozone Layer.
Lightning naturally fuses O2 (Diatomic Atmospheric Oxygen) into O3 (Ozone).

The ozone hole and GW are almost entirely separate problems. GW is caused by human emissions of carbon dioxide, and those emissions need to be reduced to fix GW.
