Nyet. From the article I linked:kwyckemynd00 said:Well...there are a few differences.
The CFC's that were killing our atmosphere are different. I believe chlorine is the destructor of ozone, and volcanoes release MUCH more chlorine with every reaction....BUT that chlorine doesn't make it into the ozone, as it does with the CFC's.
So, that is a very different scenario.
Invalid Link RemovedDr. Ken Rubin said:...
Volcanic eruptions account for a large flux of chlorine from land to the atmosphere on a yearly basis. This is in addition to chlorine that enters the atmosphere from sea spray, industrial processes and biological gases. All of these inputs occur near or at the base of the atmosphere (the planet's surface). Very little of the material emited from volcanoes makes it up into the higher reaches of our atmosphere (the stratosphere) where it could affect the ozone layer, however. Most of it is believed to be depositied lower down (in the troposphere), where it then rained out back to the surface of the earth. Only during fairly rare, large, explosive eruptions, such as occured a few years back at Mt. Pinatubo, do large amounts of volcanic gases reach the stratosphere.
So why do chlorofluorocarbons reach the upper atmosphere when they too are only input at the base of the atmosphere? Because the latter are much more stable in the lower atmosphere, so they become well distributed and make their way to the stratosphere via atmospheric circulation. On the other hand, chlorine from volcanoes is usually emitted as hydrochloric acid (HCl), chlorine gas (Cl2) or volatile compounds such as lead chloride (PbCl2). Each of these is far more water soluble and/or reactive in the lower atmosphere (as compared to chlorofluorocarbons) so these volcanic gases tend not to be as uniformly distributed in the atmosphere following injection by a volcano.
So, does volcanic chlorine affect the ozone layer or not? Well, possibly it does, since even if only a small amount of the total chlorine input to the atmosphere from this source makes it to the stratosphere, it could still be a significant portion of the total amount of reactive chlorine-bearing compounds there. However, the rate of volcanic activity over a 100 to 1000 year interval has not, as far as we can tell, changed drastically for much of the past million years; the level of ozone in the upper atmosphere has also not changed drastically over this period (until recently). Thus, it may be true that chlorine from volcanoes helps keep the production of ozone from oxygen gas in check by limiting it's build up, but it is not likely that our present ozone woes are due to this source of chlorine.

I know...did you NOT read my post?Nabeshin said:From that article:
The question you asked about volcanically-derived chlorine and the ozone layer is a good one, since this is an area of active debate (as are most issues related to the ozone layer).
And this individual's side of the debate comes without sources. When Mt. Pinatubo erupted, ozone levels were measurably "damaged." It kicked out more "greenhouse gasses" than humans did during the entire industrial revolution, and it cooled the globe by 1degC. Invalid Link Removed. Any de-explanations of the significance of volcanic activity must account for this.
Just because he's an "expert" doesn't mean he gets a free pass. He has to prove his position. Positing that volcanic cycles have remained constant does not yield a corollary of non-causality of depletion of atmospheric O3. If you disagree, then prove it. Your "expert" did not.kwyckemynd00 said:I know...did you NOT read my post?
I said you brought up "one occasion" and you totally ignored that the expert declared that volcanic activity is most likely not the cause for the recent increase in ozone decay.
He specifically stated that volcanic cycles have not changed (as far as they know) for quite a while, yet the O3 decay has been significant. I'll leave the rest up to you to figure out![]()

CO2 concentration in our atmosphere is insane and it is correlated with our burning of fossil fuels.

[/font]Dr. Richard S. Lindzen said:" . . . the science is by no means settled. We are quite confident (1) that global mean temperature is about 0.5 degrees Celsius higher than a century ago; (2) that atmospheric levels of carbon dioxide have risen over the past two centuries; and (3) that carbon dioxide is a greenhouse gas whose increase is likely to warm the earth (one of many, most important being water vapor and clouds). But – and I cannot stress this enough – we are not in a position to confidently attribute past climate change to carbon dioxide or to forecast what the climate will be in the future. That is to say, contrary to media impressions, agreement with these three basic statements tells us nothing relevant to policy discussions."

Bernard Switalski said:Example....One fine day in the year 156 A.D., in Phrygia (now part of Turkey), the prophet Montanus suddenly reeled round and round and keeled over into a trance in which he envisioned Christ's second coming and the end of the world. Thenceforward, Montanus roamed the dusty paths of Asia Minor, proclaiming to all who would listen that doomsday lay just round the bend.Montanus gathered many disciples, among whom was one Quintus Septimus Florens Tertullianus, Tertullian, who went on to become a champion of Monantism and a dynamic intellectual force and teacher in the early Christian church.At the core of Tertullian's teachings lay his bitter admonition that life in the 2nd century had become "too extravagant, too wasteful", and that "population growth had run out of control"."Mankind was raping the Earth of its resources", Tertullian warned grimly...
"...we men have actually become a burden to the Earth ... the Earth can no longer support us...".
And, to escape total planetary destruction, mankind had to withdraw to the past and practice severe asceticism, living in a simpler more natural state.

If memory serves, I didn't state that volcanoes are the cause of our "current phenomenom." I further believe that I was interested in the effects of volcanic eruptions on ozone levels, not CO2 concentrations.
Nevertheless, I would like to point out the irony of your choice of source. It's one of my favorite sites that argues against the "theory" of global warming. It makes for an Invalid Link Removed, if you are so inclined.
And yes, I read your expert's post. If your implication is that when Mt. Pinatubo erupted, ozone levels weren't reduced, your implication is wrong.
Invalid Link RemovedSince 1974 scientists have known that chlorine can destroy ozone, but no one thought the destruction would be very rapid. Events over the Antarctic region proved them wrong. The ozone hole story began at Halley Bay in Antarctica, where British scientists had been measuring ozone in the atmosphere since 1957. In 1976 they detected a 10% drop in ozone levels during September, October, and November—the Antarctic spring. Since ozone concentrations over this region often vary from season to season, the researchers weren't concerned, even as the springtime declines occurred repeatedly. It wasn't until their instruments registered record low levels of ozone in 1983 that they realized something important was happening. By then, record springtime ozone declines had occurred during seven of the previous eight years.........
Probably not even that high, and earth will reach some sort of homeostasis at any given level. BUT the concern is the weather conditions and the living conditions we will have to endure as a result of changing our atmosphere.CDB said:.....
More generally, CO2 as a percentage of atmospheric content was around 1% in the age of the dinosaurs. They were living quite well, it was a bit warmer then and plant and animal life were flourishing. What's it at now, .3% to .4%?....
As I said before, if your only proof is expert opinion, we must agree to disagree. I'm sorry if I've blown that out of proportion, it was not my intention. This reliance on expert opinion reocurring theme among those I debate in this matter, and when you feel as negatively about that "epistemology" as I do, you tend to seize on it.kwyckemynd00 said:And, I don't know why you're so hung up on that expert opinion thing...I made one reference to a guy being an expert in his field, and you blew that waaaay out of proportion.

And, CFC's still cause major damage, regardless.Well, what about that Antarctic "ozone hole?" First of all, it isn't a "hole." The "ozone hole" is a temporary, chlorine- enhanced thinning of the O3 layer over Antarctica during our (northern) autumn months. It requires the following meteorological ingredients: (a) a lengthy polar "night" -- i. e., a prolonged absence of UV radiation. This allows (b) the buildup of chlorinated compounds, unmolested by UV, in the (c) "polar vortex" -- a vast, self-contained whirlpool of air over the Antarctic region. The vortex largely isolates polar air from mixing with air outside the region, thus diluting the chlorine concentrations. Now add (d) super-cold, high-altitude temperatures, which causes ice clouds to form in the stratosphere. The ice crystals provide surfaces upon which chemical reactions between chlorine and ozone can take place much more rapidly and efficiently than by mere mixing in the air. Finally, add (e) the sudden appearance of the sun after the long polar night. This adds high levels of UV to the chemical soup, which breaks down chlorine compounds into their constituent elements -- such as highly reactive chlorine monoxide. The chlorine monoxide -- not the CFCs themselves -- then reacts on the surfaces of the ice crystals with ozone molecules, breaking them down.
A few weeks later, as the polar weather changes, the vortex breaks up, allowing the infusion of outside air into this chemical "soup" -- and soon, all the reactions stop. Ozone is then rapidly and naturally replenished by solar UV action on oxygen, and the "ozone hole" quickly refills.
If ANY of these ingredients are absent, you won't have ozone depletion. And the ONLY place that has them all is Antarctica. Even the Arctic region does not have as well-defined and isolated a vortex, because mountains there break it up. Nor do the stratospheric temperatures there get as cold...which means you don't get an abundance of ice crystals to act as a catalyst for accelerating the chemical reactions.
