How on Earth can we have greenhouse gas accumalating around the world, when we have got a whole in the ozone layer the size of Australia?

The ozone layer is repairing itself.

Just to clarify -
Ozone gas reaches a peak density of a few parts per million at an altitude of about 25 km (16 miles).
The 'hole' in the ozone layer is a metaphor. There is a decrease in the density of ozone at that level in the atmosphere over certain parts of the planet.
This 'thinning' of the ozone component is what is called the hole.
Since ozone only makes up a few parts per million at best, the overall density of the atmosphere is almost unaffected!
These is no hole leaking gases from lower down in the atmosphere!

The hole in the ozone layer over the poles varies in size from one year to the next. For all we know, it always has. As for greenhouse gases. Yes, we do put out GH gases all around the world. (Al Gore thinks only Americans do.) But one thing the global warming activists don't talk about is the evidence that the earth has been warming for a long time. Only room here for one example. A British captain and explorer/surveyor, named Cook, mapped the coast line from around Oregon, north to what is now southern Alaska for the British government. He included several glaciers on his maps. This was in the 1770s. By 1890, only remnants from a few of those glaciers remained. There is much more. Wish there was more room to tell more. We've had four ice ages in the past, and I'm sure the earth has had warming periods in the past too. Don't tell Al Gore you heard it from me.

The hole in the ozone layer is not like a hole in a ballon; gas isn't going to leak out through it! The various gases are kept here by the gravity of the earth.

Yeah! This has puzzled me for years. Apparently the hole in the ozone layer expands and contracts - this must mean the hole is sucking G-gas out into space. Right? Kind of like an upside down plug-hole thingy.

The Ozone Hole has not changed since the International Geophysical Year, 1957-8. It has always been there as a natural fact not a First World anthropogenic atrocity.
The single largest national emitter of carbon dioxide is.... China.
