On the heels of Andrew Dessler’s Ozone Hole tweet, we have from the BBC:
“Researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere from as yet unidentified sources.”
“Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer.
Two of the gases are accumulating at a rate that is causing concern among researchers.”
“Other scientists acknowledged that while the current concentrations of these gases are small and they don’t present an immediate concern, work would have to be done to identify their origin.
“This paper highlights that ozone depletion is not yet yesterday’s story,” said Prof Piers Forster, from the University of Leeds.
“The concentrations found in this study are tiny. Nevertheless, this paper reminds us we need to be vigilant and continually monitor the atmosphere for even small amounts of these gases creeping up, either through accidental or unplanned emissions.
“Of the four species identified, CFC-113a seems the most worrying as there is a very small but growing emission source somewhere, maybe from agricultural insecticides. We should find it and take it out of production.”
The paper “Newly detected ozone-depleting substances in the atmosphere” Laube et al., paywalled, can be found here:
“Ozone-depleting substances emitted through human activities cause large-scale damage to the stratospheric ozone layer, and influence global climate. Consequently, the production of many of these substances has been phased out; prominent examples are the chlorofluorocarbons (CFCs), and their intermediate replacements, the hydrochlorofluorocarbons (HCFCs). So far, seven types of CFC and six types of HCFC have been shown to contribute to stratospheric ozone destruction1, 2. Here, we report the detection and quantification of a further three CFCs and one HCFC.”
“Our observations on air samples collected in remote regions of the atmosphere show the presence of four previously undetected ozone-depleting substances (ODSs). We have identified and quantified CFC-112 (CFCl2CFCl2), CFC-112a (CF2ClCCl3), CFC-113a (CF3CCl3) and HCFC-133a (CF3CH2Cl) in the atmosphere (Fig. 1). We have reconstructed their past abundances from air extracted from deep polar firn, which can provide a natural archive of atmospheric composition up to about a century back in time5. Our firn air measurements suggest that all four newly reported compounds are anthropogenic (see also Supplementary Information), with insignificant atmospheric abundances before the 1960s.”
For reference, the images the head of this article show the current Northern “Ozone Hole” within the Northern Polar Vortex, at 10 hPa/mb – Approximately 31,000 meters (101,700 feet). Draw your own conclusions…

This may be ground breaking research and the authors may be absolutely correct. But after reading Phil Jones emails, I simply cannot take anything that comes from the University of East Anglia seriously.
“Has anybody ever measured the amount of CFCs or chlorine actually in the “ozone hole” over time?”
Surely you jest? There’s a computer model behind every tree!
Supplemental information at least is not behind a pay wall. http://www.nature.com/ngeo/journal/vaop/ncurrent/extref/ngeo2109-s1.pdf
…and if you remove agricultural insecticides farmers will have no choice but to buy Monsanto’s GMO crops. Then there’s reduced crop yields, starvation… the usual Globalist Order out of chaos tactics toward a world control grid.
“Ozone-depleting substances emitted through human activities cause large-scale damage to the stratospheric ozone layer, and influence global climate”
Um, um, well yeah maybe, but since ozone is a greenhouse gas the influence should be one of lowering temperatures which if alarmists are right should be a good thing.
Too much Guacamole?
We always say: “You just can’t make this $hit up.” They, however, seemed to have found a way.
“We should find it and take it out of production.”
that tells you everything you need to know: Luddites on the march again!
Do I have to read it ?? The words “East” and “Anglia” should be a clue as to why not, but I probably will – maybe when I need an ironic laugh.
It is further believed that though the concentrations of these gasses are small the govt grant potential is rather large. Woo woo the gravy train is leaving the station.
They are not out to save the planet but to destroy mankind.
The only threat to the Ozone layer is stratospheric volcano eruptions. Or at least that is what the actual data says. This seems to be an issue that climate science/gravy train ignores as much as possible.
Researchers from the University of East Anglia declare –
“Good news everybody! We’ve discovered fresh supplies of Doooom!”
But then they would, wouldn’t they? No-one is buying their old stock and it’s seriously past its use-by date.
Science is easy when you start with two simple postulates:
Humans bad.
Nature good.
Personally I don’t like any kind of insecticides, but it is hard to live without them. But if they were that dangerous, they would affect humans and animals too. We now take great care where we spray them, and there are laws governing this. Such as wind drift, aerial spraying etc. And protective clothes and masks. These jokers are really don’t meet the mustard.
Allan that is their philosophy and unfortunately in someways we have damaged the landscape, but nature seems to rebound well, one cliches used by archaeology and palaeoanthropologists is
“Humans propose but nature deposes” No rain, crops and people die. Sudden volcanic eruptions can cool the planet and cause a nuclear winter. And large density cities cause their own UHI and pollution. etc, etc., etc. And an other glacial period will greatly harm the Northern Hemisphere, don’t you think they already know this? That’s why they are ignoring the medieval
mini ice age.
When they have exhausted (excuse the pun!) the hazards to the planet of man-made gases, there are two other states of matter (man-made) that no doubt will lead to Armageddon!
Does a degree from the University of East Anglia have the initials BAtdwSc (Bugger All to do with Science) ?
Why the heck would anyone listen to these ahem, “experts” about anything at this point?
Eye-roll worthy, is all.
“……with insignificant atmospheric abundances before the 1960s.”
Ummm, somebody help this dumb engineer out. So they occur naturally, but ‘not in abundance’?
Analytical instruments are becoming so sensitive that you find practically everything anywhere you want. If I want to find cancer in your toothpaste or explosives in your bubble gum, I will. We can expect ever more of these scare stories in the future.
What leads these folks to claim these agents “could be from agricultural insecticides.”? That’s a bizarre thing to claim without explanation. To throw in my own out-of-left-field possible origin : could solar panels be emitting such agents? After all, agricultural insecticides have been around for a very long time, solar panels not very long.
Fluorinated Drinking Water (Fluorine) and Water Treatment (Chlorine and carbon and bacteria)?? (remember fluorine started to be added post WWII but really ramped up in the 1960’s)
Oh nooes!!!
Bueller? Bueller? Anyone? Anyone?
That’s my hypothesis, where is my grant for the research and to develop an alternative??????
Jut give me money, money, that’s what I want.
Zombie Science strikes again.
So lets get this right, CFC’s don’t “destroy the ozone” above Industrial Centres where they are released but migrate too & have an annual jamboree and convention every year at the same time in Antarctica.
Extraordinary really when hardly any atmospheric water vapor from other latitudes can penetrate the Circumpolar winds surrounding Antarctica, thus making it the driest continent on earth.
So ozone is not in a layer but is formed in the Ionosphere as solar UV hits O2 – this “hole” forms during the Antarctic winter where no UV has been wrecking O2 to form Ozone – and we blame a gas as the ‘guilty party’ ………. Detective Colombo would still be asking questions !
Now to pull some gaseous names out of my..
The odour of desperation in 4 flavours.
Wet climate scientist, more foul than we dog.
Frightened parasite, oh my god, I’m going to have to get a job.
Musty academia, long past its best.
Stale sponge, the grants are over.
Yes terrible gases are building up in the atmosphere of East Anglia, better nuke it , before they spread.
Thats the precautionary principle ain’t it?
Ah ! The busy Boffins of the Anglican Church speak. Hallowed be thy name.
A reference for the virus of Anglicanism ! http://en.wikipedia.org/wiki/Anglicanism
Yes. What a conundrum. The “ozone hole” north and south since 1989 comes and goes, comes and goes, seemingly irrespective of the prescriptions of the Boffins of the Anglican Church.
How dreadful.
The Boffins since 1987 must be in a terrible fixation.
Ah Ha !
The “Keeling Curve” keeps ever rising. http://en.wikipedia.org/wiki/Keeling_Curve
Yet Global Temperatures on average are, flat.
Robin, “Batman, could it be that the Earth’s atmosphere in regards to CO2 concentration, assuming the measurement of CO2 concentration is legitimate, is insensitive to CO2 concentration ?
Batman, “If we assume the CO2 concentrations are legitimate then both the Montreal Protocol and the assumptions of IPCC Anthropogenic Global Warming are false.”

Batman, “Ditto. Now you see the evil we are up against.”
