Mysterious new man-made gases pose threat to ozone layer…

By WUWT Regular “Just The Facts”

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…

The Ozone-CFC Debacle: Hasty Action, Shaky Science – http://heartland.org/policy-documents/ozone-cfc-debacle-hasty-action-shaky-science

Sounds like another strawman argument.

I guess when you know the global warming meme is dying, it is time to start a new paranoia fest for the greenies.

“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.”
In other words: “We’re for sale. Give us lots of money and we’ll point the finger at some aspect of civilization and ramp up the threat. Act now and we’ll throw in a hockey stick for free.”

Chris @NJSnowFan

They say could be from agricultural insecticides but what about resins from carbon fiber resins from wind turbine blades and solar panel manufacturing new types of Industry with new chemicals

Obviously CO2 is no longer the gravy train it once was. Time to rustle up a new bogeyman (or six.)

Chris @NJSnowFan

There are many types of men chemicals also from pharmaceutical companies

Sean Peake

I went looking for the underlying BS and found it in the last line: agricultural insecticides.

Joe Public

“Two of the gases are accumulating at a rate that is causing concern among researchers.”
Could that rate be ‘insignificant’, as in:- insufficient to justify numerous research grants?

Read “UEA” and stopped reading. How many think that credible science is done there? Perhaps there is, but if it says “UEA” on anything, I hesitate to read it except for entertainment purposes. Even scanning it, the BS meter works overtime. I wonder if they realize how much damage they have done to their reputation?

Latitude

memo to staff: People aren’t buying the whole CO2 thing any more…..we need to come up with at least four more dangerous man-made gasses

Draw your own conclusions…
I have, and it’s not very flattering to those pushing this (yet another) scam.
I’m catastrophied out and don’t believe one iota of what they claim and they only have themselves to blame.

Somehow, I don’t think that this dog is gonna hunt. Back to the drawing-board, grant junkies!

In other words, our hysterical bleatings and banning of Freon didn’t stop people from being able to have air conditioning, the plebes need to suffer for Mother Gaia, they were too darned smart and found a way to do it without old Freon. We’ll fix their wagon, and their little dog too!

Gary Pearse

““Researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere”.
Whack-a-moley science. NASA reports ozone hole is not going away a month ago and UEA comes out with a paper discovering “new” substances – suspiciously all Chlorfluorocarbons. Hmm … this is a bit over the top. The rapid response team is good!
With the complex nature of the chemistry involving UV light turning loose individual Cl atoms, how do these guys know that they aren’t products of the reaction with the old CFC. What if they are natural. Seawater contains some fluorine (<1ppm) and chlorine is known to be abundant enough from salt spray from the sea to put HCl adrift. Add the "newly discovered" organic chemical haze from forests to the mix….
I think O-hole alarmists have been getting the jitters recently with, despite 35yrs of UV eating up CFCs the O-hole just won't go away and CFCs really should have been significantly reduced by now to show some progress. Okay, consensadores, we got to find more bad, secret ozone destroyers. When the hockey stick was broken, new hockey stick papers popped out like pop corn; when we had 1/6th of a century of no warming, we started getting papers on hot spots whizzing around the world to fast to keep track of and the devious heat also started heading for the ocean deeps. Oh and Dessler, it appears you didn't save our lives after all! Were still going to be doomed.

CFC-113a seems the most worrying as there is a very small but growing emission source somewhere, maybe from agricultural insecticides
And THERE is the target of this BS.
The O-hole has remained pretty much the same for all the years of observation; I’d say it’s a natural phenomenon due to, oh say, magnetic fields, particle streams and suchlike.

lets see: ban Agricultural pesticides, cause global famine, blame climate skeptics.

Bill H

Target mans ability to safely store food.. Create Food.. Just more of the same from these slugs.

similar to: ban nuclear energy, cause global warming, blame fossil fuel industry

“The researchers are concerned”. How the liberal media loves the University of East Angliaphile.
My guess the chemicals are emitted from the manufacture of compact fluorescent light bulbs.

H.R.

I’m pretty sure that research grants are causing the ozone hole. Stop funding ozone hole research and you’ll never hear another peep about that pesky ozone hole.

davidmhoffer

“Of the four species identified, CFC-113a seems the most worrying as there is a very small but growing emission source somewhere,
Yeah… like maybe someone somewhere still makes the stuff by the barrel? Nah, couldn’t be. If that existed, it would be run by mad scientists in a secret lab with security guards and and anyone who found out about it would be shot and dropped in the ocean with cement boots to keep the info out of the public. You’d never be able to just google it and buy it by the barrel right off the internet, that would never happen….

Has anybody ever measured the amount of CFCs or chlorine actually in the “ozone hole” over time?

Louis Hooffstetter

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.

Severian

“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!

R. Shearer

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.

“We should find it and take it out of production.”
that tells you everything you need to know: Luddites on the march again!

philincalifornia

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.

Damian

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.

Bill Illis

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.

Konrad

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.

bushbunny

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.

bushbunny

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.

Karl

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.

Peter Laux

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 !

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.
