Odd report

Kell

To those more knowledgeable bods, I was told that there was a report on the news recently that the Ozone layer is beginning to repair itself. Anyone got any more on this or is it complete bollíx?

Cheers,

There was a thread, here about this b4.

Also on the rte website, there is some inof on the subject.

It depends what you mean by 'repair'.

In South America, it is still the case that the Antartic hole, gets so large that it sometimes bathes the southern regions of South America in up to 30%(or in the region thereof) more UV light then is normal.

However, without CFCs depleting the ozone layer, it will eventually repair.

Global warming (wether you accept the correlation between the two phonema or not), however is still increasing, which is, at least in my opinion, worrying.

Yes. I have read with much interest your views on the topic my friend.

SciAm have an online article about it : http://www.sciam.com/article.cfm?articleID=000D19A5-F60B-1F26-8D4A80A84189EEDF&pageNumber=1&catID=1

The ozone layer is not repairing per se...its rate of erosion is slowing.

And that's a distinction worth noting. It's like the rate of inflation dropping from say 5% to 3%. it doesn't mean that it's cheaper to live this year - it just means that it's less more expensive


a fact I tried to explain to the Examiner reporter who didn't get it either in his front page report on the cost of living or after I emailed him nicely to explain (he also didn't get that a drop from 5 to 3 is not a 2% drop, it's a 2 percentage-point drop:rolleyes:

Right... except for the fact that we've replaced CFCs with CFHCs ? or something similar, which are still harmful, but not quite as bad?

(typical?)

As far as I remember my Newsweek articles, the Antartic ozone hole is still growing.

In theory without depletionary chemicals, the layer would repair, however as far as I'm aware, as it stands, the ozone hole is still in a state of growth.

so it looks like we are back to the idea of a fleet of tanker planes pumping out sulphur dioxide over antartica

Yeah thats a thing that has bugged me. The biggest whole is over the antartic, But the greatest use of CFCs/greenhouse gases is in the nothern hemispere. I know threr is a hole over the artic and other places aswell, but still no one has really explained that to me. Any idea why that is so?

Where are the terraformers, building big ozone-creating machines? Maybe only in the novels of Kim Stanley Robinson?
