GENEVA (Reuters) - The hole in the ozone layer above Antarctica has grown to near record size this year, suggesting 20 years of pollution controls have so far had little effect, the United Nations said on Friday.
In a bulletin on the seasonal depletion of ozone gas, which filters harmful ultraviolet radiation that can cause skin cancer and cataracts, the U.N.'s World Meteorological Organization (WMO) said the hole would peak within a couple of weeks.
"It will probably not break any records, but it shows that ozone depletion is going on and that the so-called ozone recovery has yet to be confirmed," Geir Braathen, WMO's top ozone expert, told a news briefing.
U.S. scientists reported last month that the ozone layer has stopped shrinking but it will take decades to start recovering.
The hole above the South Pole and Antarctica, which spans about 27 million sq km, was expected to grow another million sq km in a week, bringing it close to the record years of 2000 and 2003, the WMO said.
It had passed over Ushuaia, in the Patagonia region of southern Argentina, "leading to noticeable increases in UV (ultraviolet)" radiation, according to the bulletin, issued on the International Day for the Preservation of the Ozone Layer.
Chlorofluorocarbons (CFCs) containing chlorine and bromine, have been blamed for thinning the layer because they attack the ozone molecules, causing them to break apart.
Many CFCs, once commonly used in refrigeration, air conditioning and industrial cleaning, were banned by the Vienna Convention, signed exactly 20 years ago, and its Montreal Protocol clinched in 1987.
Most scientists say the hole spanned a record 29 million sq km (11 million sq miles) in September 2003, exposing the southern tip of South America.
"You could say that the ozone situation is stabilizing at a low level. We are approaching the maximum of ozone depletion, it is kind of leveling off, but it is still too early to say that the situation is improving," Braathen said.
In a statement, U.N. Secretary-General Kofi Annan said that the 189 states to have ratified the Montreal Protocol had eliminated more than 1.5 million tonnes of annual production of chemicals that destroy the ozone layer.
But developing countries were "only at the half-way point in many of their obligations" under the pact, while in wealthy countries a number of chemicals still needed to be phased out.
"It is essential that we remain alert to this hazard to avoid an increase in skin cancers, cataracts and other health threats," Annan said.

We're all gonna die!
So maybe the planet does this...I don't know...IRRESPECTIVE of what we humans can do to it?
HA! Had you didn't I! Oh, we all know that this was caused by Haliburton/Bush/Karl Rove, more than 20 years ago...they are THAT good at making conspiracies. < /sarcasm>
So in otherwords we were better off with flourocarbon sprays because the more we cut back, the bigger the hole gets! PEOPLE WE NEED TO POLLUTE MORE!!!
what a confusing pile of gooblygook..first it is record size..then it has not grown..then it is no bigger than in 2000 and 2003..then it is said to be leveling off..blahblahblah...lol
There. I just made it worse...
"U.S. scientists reported last month that the ozone layer has stopped shrinking but it will take decades to start recovering."
If they didn't know that our efforts would be 'fruitless' 20 years later, how do they know that it will take decades to shrink; or if it will at all?
I call "B" as in "B"
And "S" as in "S".
Why are we screwing around and spending money rebuilding New Orleans if we are all doomed anyway? First John Roberts and now this. Like the above poster said, "We're all gonna die!"
I guess if we plugged the hole then there would be nothing to complain about.
1. A blue gaseous allotrope of oxygen, O3, formed naturally from diatomic oxygen by electric discharge or exposure to ultraviolet radiation. It is an unstable, powerfully bleaching, poisonous oxidizing agent with a pungent, irritating odor, used to deodorize air, purify water, treat industrial wastes and as a bleach.

So how DO you spell China?
Sounds a little like "put that where the sun don't shine!"
You mean it's not at 'record size' already? I thought the hole in the OZONE layer was larger than it had ever been and expanding every day. I thought the end of the world was at hand. And NOW you tell me it's not even at record size, yet? Well I guess I'll have to stop backing the Global Warming/KYOTO will save the world crowd...
As little or no sunlight has hit the Antarctica for the past several months, one could conclude why the ozone hole has grown.
I would expect to see a similar article regarding the Arctic Circle in March 2006.
Of course, the first time they looked for the hole, it was there. It may will have been there for the last million years.
...unless the desired effect was increasing taxes, costs to consumers and government red tape. In that case, pollution controls have been a resounding success! Actually accomplishing anything useful is waaaaaay down on the list.
OMG..that is hysterical! LOL, thanks for the link.
As does the hole in Nancy Pelosi's head

impurities in our air and water that are doing it." --Al
Gore, Vice President
lol..u guys are cracking me up!!
I had to read that 4 times to be convinced it didn't say
"Collective democratic A-hole nears record size"
must be friday or something...
W-A-L M-A-R-T......That's how I spell China.........
once that ice completely melts, I bet there's is going to be some damn good fishing going on
She really should sue that doctor who did her facelift...........
I have been looking out the window up to the sky for the last hour and I still don't see any hole.
Damn! If only we had put Kerry in d'house! I tried to tell you guys!!! It's all over! I've said it all along! Gosh! Golly! and double damnation three times over!
If You Can't Dazzle Them with Brilliance, Baffle Them with BS.
It's the biggest hole in the ozone in... in...
well, uh, in the 6 or 8 years we've been able to measure it...
Ouch right in my eye, dag nabbit!
As someone who grew up in the Finger Lakes region of New York, I am thankful for global warming or else I would have been forced to live atop a glacier.
Now that Winter at the South Pole is ending and the South Pole is again turning towards the Sun, sunlight will once again be able to strike the atmosphere above the South Pole and ultraviolet light will once again be absorbed by oxygen molecules in that atmosphere, thereby creating new ozone molecules, which will shrink the "Ozone Hole".
This will process will continue until March 2006, when the South Pole will turn away from the Sun. Then, with no new ultraviolet rays acting on oxygen to create ozone, the equilibrium point will change and the number of ozone molecules will diminish, creating an appearance of a growing "Ozone Hole" as Winter at the South Pole progresses.
Then, in September 2006, Winter at the South Pole will end and the South Pole will once again turn towards the Sun, sunlight will once again strike the atmosphere above the South Pole, and ultraviolet light will once again be absorbed by oxygen molecules in that atmosphere, thereby creating new ozone molecules, which will shrink the "Ozone Hole".
This process will continue until March 2007, when the South Pole will turn away from the Sun. Then, with no new ultraviolet rays acting on oxygen to create ozone, the equilibrium point will change and the number of ozone molecules will diminish, creating an appearance of a growing "Ozone Hole"...
I guess it's too much to ask that the "scientists" who do these junk "studies" first learn a little about chemical equilibrium: 3 O2 => 2 O3 => 3 O2 => 2 O3...
Or the impact of the Earth's axial tilt on our seasons...
Essentially saying what you are!If 20 years of pollution control has'nt improved anything,THEN IT'S NOT POLLUTION!Besides,this country does not produce anything anymore and our temperature has been getting steadily cooler since the 1950's.
It is frequently alleged that the "ozone hole" (actually a seasonal thinning of stratospheric ozone in the South Polar region and not a "hole" at all) was "discovered" in the 1980s, subsequent to significant use of anthropogenic chlorinated fluorocarbons in the 1960s through 1980s. This is simply not true.
Atmospheric ozone is measured in Dobson Units, named for the Oxford academic Gordon Miller Bourne Dobson (1889-1976), one of the pioneers of atmospheric ozone research and inventor of the Dobson Spectrophotometer, used to measure atmospheric ozone from the ground. During the International Geophysical Year of 1956 there was a significant increase in the number of these devices in use around the globe and the Halley Bay (Antarctica) anomaly was discovered. Yes, that's 1956, three decades prior to the allegedly alarming "discovery." There was a significantly different perspective then because interest was focussed on the November increase - now called a "recovery" - in stratospheric ozone levels over Antarctica with the collapse of the South Polar Vortex.
Doubtless we'll get more hand wringing over poor irradiated Punta Arenas but everywhere around the world between 45N and 45S, where the bulk of the planet's human population lives, receives more solar radiation on any normal day than does Punta Arenas on the most severely irradiated day or two every few years when a patch of ozone-reduced atmosphere passes between the tip of South America and the sun.
Is said "hole" of any particular significance to humans? Probably not - unless you intend sunbathing in South Polar regions in September. Even so, you would be risking (besides frostbite) sunburn but apparently not an increased melanoma risk. Why? Because melanoma and genetic damage is primarily associated with tissue-penetrating UVA (ultraviolet radiation in the 320-400 nanometer [nm] band) exposure and alleged ozone depletion is completely irrelevant to UVA levels experienced at surface - UVA is simply not blocked by atmospheric gases.
What a bunch of CRAP!!!!!!!!!!
Ozone is created when radiation enters the atmosphere and strikes water.
When the "layer" is thin, more radiation enters an creates more ozone!
It's a self healing process and about a 3 to 5 week cycle.
The rest of this hysteria is CRAP!!!
Just what I was thinking. Those bad CFC's that come from an aerosal can.
If not WHY NOT??????
i say plug it with kennedy's head!!!!!!
