New study confirms that nature is responsible for 90% of the Earth's atmospheric acidity

From the UOW, nice to see that man isn’t the culprit in this case.

University of Wollongong60 Years, 1951-2011

UOW data confirm surprising atmospheric findings

Dr Murphy and Professor Griffith with the suntracker of the solar Fourier transform spectrometer that backed surprising satellite readings linking most formic acid emissions from forests

By Melissa Coade – Satellites showing that nature is responsible for 90% of the earth’s atmospheric acidity shocked researchers from the Belgian Institute for Space Aeronomy, whose findings have just been published in the journal Nature Geoscience.

Stunned, the scientists approached a team from the University of Wollongong’s Centre of Atmospheric Chemistry (CAC) to confirm what satellite readings were telling them.

By providing data from a ground-based solar Fourier transform spectrometer instrument at the University, CAC used 15-years worth of information to verify the satellite’s story: all existing global models had substantially misjudged the main source of formic acid levels on earth – its forests.

UOW Physical Chemistry lecturer Dr Clare Murphy (Paton-Walsh) made the first measurements of formic acid with the instrument as part of her PhD looking at the atmospheric emissions of bushfires.

“The instrument provides a spectral record, of which you can analyse for a whole number of different gases, and formic acid is one that is relatively new,” Dr Murphy said.

“The modelling shows, particularly, that natural forest emissions have been highly underestimated. Our forest areas are producing more formic acid than we ever thought,” she said.

Dr Murphy said the unexpected results might well mean forests are responsible for most of the acidity in rainwater in areas other than highly-polluted inner-cities.

“Our instrumentation has global significance because the number of facilities in the region are very limited. In order to capture some of the major forests of the Southern Hemisphere this machine was crucial,” she said.

In the atmosphere, formic acid impacts a number of important pH-sensitive chemical reactions such as the production and loss of radicals affecting the ozone. Quickly absorbed by microbes, formic acid is not associated with the harmful effects of acid rain.

According to CAC coordinator and co-contributor Professor David Griffith, the results provide a whole new angle to existing knowledge about our atmosphere.

“When it comes to understanding the fundamental chemistry that goes on and the whole oxidiative cycle, where formic acid has an important impact is that it is one component of the soup which controls the ability of the atmosphere to oxidise pollutants and get rid of them,” Professor Griffith said.

“Normally you take your measurements and might make a 10 or 20 percent adjustment to an estimate of a source but here we’ve proven by several factors that our understanding was wrong,” he said.

The study showed that terrestrial vegetation accounts for 90 percent of annual formic acid production. Other sources include fossil fuel combustion, agriculture and biomass burning.

Alongside UOW co-authors Dr Murphy and Professor Griffith worked CAS members Dr Nicholas Jones and Dr Nicholas Deutscher.

I wonder why scientists would be shocked or stunned by the results of their observations.
Seems to me that one would just accept the results one gets, and report them, without having to psychoanalyse the results.

Well, that’s a shocker….. ‘we’ve proven by several factors that our understanding was wrong,”
Still, I’m going to need an atmospheric chemist to explain the implications. Isn’t formic acid simply hydrogenated CO2? And then if it gets gaseous doesn’t that make a whole host of implications? How much are we really talking about? My experience with it is limited to allergies and anaphylaxis considerations. Can we desensitized people by having them walk around in the woods?

The Belgian study last month actually shocked Fred Pearce of New Superstitionist into admitting a bit of truth for once:
http://www.newscientist.com/article/dn21298-trees-do-bear-some-blame-for-acid-rain.html
I seem to recall that the specific acid-rain scare in NE USA was disproved quite a while ago by a study of wind patterns; the forests in question couldn’t have gotten the pollution from the accused power plants.
Now it’s especially good to see the whole theory, not just the specific distribution, disproved twice!

January 11, 2012 5:29 pm

Formic acid has long been known to be a result of the oxidation of natural methane formed during the anaerobic decomposition of organic matter. Formic acid as an air pollutant is generally an indoor problem – and is especially of concern to museums. This research is interesting, but doesn’t seem to have much significance to climate change.
“The modelling shows, particularly, that natural forest emissions have been highly underestimated.”
I don’t have a problem with models.

Now that strikes a note in the old grey cells..
when designing timber (lumber ) drying sheds for European Woodland use, the 2 biggest problems for the shed materials always was the gases given off during drying; to cut a short story even shorter, you get Formic Acid and Lactic Acid, which sort of caused problems with cement based structures, (except for the fact that they had half dismantled themselves by the time the timber in the area had been cleared)
So it seems quite realistic.

No, formic acid is the product of oxidation, not reduction/hydrogenation. Methane and terpenes would be likely suspects for the precursors. Forests on a warm day will develop a form of smog from hydrocarbons released by the leaves and undergrowth. CO2 is a source of rainwater acidity, too.

See what empirical research and experimentation can do. It produces surprises.
Climate science has never produced a surprise and never will. Why? Because they just do not have the instinct for the empirical or the energy for research.

Can’t find it. Multivariate analysis seems to show Ca and Mg content of rain determines pH.

A similar finding was that most aerosols found in the free troposphere (above the inversion layer and up to 7 km height) are from natural origin. That was measured by in situ sampling. In that case, the aerosol models used in GCM’s were highly underestimating the natural component. See:

I hope that Dr Murphy and Professor Griffith get lots of publicity for their work.
However I remember the 60 Minutes December 30, 1990 report of the National Acid Rain Precipitation Assessment Project (NAPAP). One thing that stood out in the report was a brief interview with an environmental activist. The reporter told him that the acid rain legislation would not help anything and the activist did not dispute that. He instead said that what was important was the legislation but did not explain why.
This article gives a good and long sequence of the events and research paid for and ignored by congress because too many people had their political power wagon hooked to the (humans are destroying the environment) horse. It also speaks of what happened to the lead NAPAP scientist Edward C. Krug.

IIRC, It was first European settlers after 1788 who invented the name “Blue Mountains” for what was originally named “Carmarthen Hills” or other names.
These are the mountains that are west and north of the University of Woolongong, and behind Sydney, where the Fourier transform spectrometer detected formic acid at high levels.
Earlier reports attributed the Blue name to particulate oils from the Eucalyptus tree spp. that are so common in East Australia, via dispersion of sunlight. One needs only eyesight to know that there are special properties in the atmosphere here, but instruments are needed to decode them.
If the eye can see radiative effects, it is quite likely that some climate effect will be caused. The radiative flux might be changed, depending on the light absorption spectrum of molecular formic acid, which I have not studied.
This is apart from its inherent acidity. Some say that the bite of a bull ant stings because of formic acid.
This is merely one more example that climate science is not settled. There are many remaining intuitive observations that lead to untested hypotheses that cause wiser heads to suspect strongly that the science is not settled. The hard data are coming in as time rolls on.
There are many natural cycles that interact with others at various times and with various strength. It is scientifically naive to single out a carbon dioxide cycle as immune from interaction with other cycles. That is one reason why so many scientists now downplay the formerly held view that CO2 was the main driver of temperature change by man.
If CO2 appears as a culprit alone in its grandeur in the next IPCC report, then we will know that there is corruption behind the science.

Formic acid, apart from its use by ants and stinging nettles as a weapon, is widely used as a de-scaling agent for removing carbonate deposits from pots, kettles and bathroom stuff. Which it does very well, liberating lots of c****n d*****e in the process.
So that’s it – the science is settled and it’s the trees what done it.

In Australia the eucalypt forests discharge millions of tons of volatile aerosols into the atmosphere. We are left out of most things being where we are, I do hope that it is us causing all these problems with our fuminous forests. These people at Wollongong need to use a different forest before concluding. Eucalypts are bad a@se trees left over from thousands of years of burning, burning, burning by the indiginous population, they are bullet proof, bomb proof and fire proof, our original flora is almost extinct. Probably an unwise conclusion.

From what I have read, its not the acidity from the rain that’s the issue.. but the acidity the rain water picks up as it passes through rotting vegetation. Lake acidification in the Adirondacks corresponded not with increased acidity of rain, but with reforestation of the region. The Adirondacks are a relatively young mountain range and is not composed of sandstone, limestone, or other sedimentary rocks that would allow the water to absorb into the ground, helping to buffer out the acidity.

I think the problem is that the labs and entrepreneurs are trying to use chemistry and bacteria. Nature has, however, done such a good job of engineering cellulose and its lignin armor to resist exactly this that it takes more energy in than you get out.
Solution: termites. They’re the reason wood rots, after all — they chew and gut-process it till it’s ready to decompose. So tame termites is the way to go! (One problem: the CO2 byproduct. Termites out-CO2 humans globally by an order of magnitude.)

“There is some scientific consensus that acid rain has destroyed life in some freshwater lakes and streams, particularly in the northeastern US and Canada and has damaged buildings and other structures.
source

Schenectady Gazette, Mar 24, 1987
By now, the issue should be clear. Sulfur and nitrogen oxides, produced in large part by industrial coal-burning plants, are forming acidic compounds that carry in the wind and fall to the earth. They are responsible for killing lakes and damaging buildings, and are implicated in even more serious damage including the death of trees and wildlife. The scientific consensus is overwhelming. Cut the industrial emissions and the acid rain will be lessened.
source

New York Times, December 31, 1989
That report said damage to lakes and streams from acid rain was limited to a few areas in the Northeast and was unlikely to worsen significantly in the next few decades. It also said that there was probably no damage to trees from acid rain except as a minor part of ”multiple stresses” at high altitudes. Laurence Kulp, who had been director of the program, resigned days after the report was made public. He was succeeded by Dr. Mahoney.
This time, said Patricia M. Irving, associate director of the project, the results are being subjected to intensive review by peers of the scientists who have done the work.
The final report of the research project is expected to include, along with the scientific consensus, an analysis of the relative costs of acid-rain damage and the benefits of reducing acid rain.
source

The Times-news, Mar 20, 1986
It recommended that the US carry out a 5-year program that would cost $5 billion, with half the money coming from private industry, to find ways to control airborne emissions of sulphur and nitrogen oxides, which are generated mostly by industrial coal-fired furnaces. These emission are chemically changed and return to earth as acidic rain, snow, or particles. A scientific consensus says these are considered responsible for damage to freshwater lakes and streams. They may also damage trees and plant life and human health.

Clearly we must send trillions of dollars to developing nations to cut down all their trees to address this horrible problem. I know, because the solution to every problem is we must send trillions of dollars to developing nations. . . .

Wasn’t it Reagan who first broke the forest story?

The role of isoprene in forest atmosphere acidity was an inconvenient topic at the height of the acid rain crisis. Martin et al in 1991 found the tree produced isoprene’s were photo-oxized to formic, acetic, pyruvic acids among others. tp://www.springerlink.com/content/g6w82815x40xj001/
The authors cautioned:
“These data indicate that oxygenated organics comprise a large fraction of the total volatile organic carbon containing species present in rural, forested regions of the United States. Consequently these compounds need to be included in photochemical models that attempt to simulate oxidant behavior/and or acidity in these forested regions.”
So how much isoprene is being emitted by US forests? From 2009 Caltech study:
“Isoprene is no minor player in atmospheric chemistry, Wennberg notes. “There is much more isoprene emitted to the atmosphere than all of the gases—gasoline, industrial chemicals—emitted by human activities, with the important exceptions of methane and carbon dioxide,” he says. “And isoprene only comes from plants. They make hundreds of millions of tons of this chemical… for reasons that we still do not fully understand.”
And the most important take away from Caltech:
“Much of the emission of isoprene occurs where anthropogenic emissions are limited,” adds Caltech graduate student Fabien Paulot, the paper’s first author. “The chemistry is very poorly understood.” http://linde.caltech.edu/articles/caltech-researchers-show-how-organic-carbon-compounds-emitted-by-trees-affect-air-quality
And it is these natural epoxides that create smog and why the Smoky Mountains are called the Smoky Mountains. The only way the National Parks can meet EPA’s haze regulations is to chop down the trees.
One last take away– the acidification of the soils and waters however has more to do with formation of organic acids in the soil/bogs than rainfall. A simple test- pour distilled water through peat moss and measure the pH -should be about 3.5-4.0. (Bogs plants biologically drive down pH -its how they prevent being overtaken by the macrophytes.)

Remember when it was terrible for government to “censor” scientists like James Hansen. Well, the government’s ritual defamation of Ed Krug and Larry Kulp was OK during the Acid Rain crisis because the scientists then were simply propaganda instruments of the Reagan Admin. The interim Acid Rain report (NAPAP) released in 1987 did not find a crisis- a finding politically unacceptable.
Representative James Scheuer (D-NY), chairman of the House Subcommittee on Natural Resources, Agriculture Research, and the Environment, skewered both NAPAP director J. Laurence Kulp and the report in hearings. Kulp resigned a week later.
When James Mahoney became NAPAP director in 1988, he “assured” Scheuer’s subcommittee that he “would not subscribe…at this time” to the view that acid rain would not harm any more Northeastern lakes.
The new Acid Rain director basically promised Scheuer that the science would not contradict politics again. How much press did a statement promising a politically correct scientific finding get in the Press? None!
Yet despite these assurances the final NAPAP report found the acid rain hysteria was unfounded with some very minor exceptions. (Try and find the final NAPAP report online- good luck)
The 60 minutes with the NAPAP lead scientist Ed Krug was followed up by a coordinated EPA smear:
“In the meantime, Rosenberg ordered his aides to prepare a response, which the EPA released on January 10, 1991. The document, which consisted of statements made in the story followed by the EPA view, was sent on request to interested parties. Said the response, “It is unfortunate that CBS chose Dr. Krug as its only scientific expert on acid rain, because Dr. Krug has limited scientific credibility even in the limited area of surface water acidification.” On the next page, the EPA document gave selected damning quotes from the secret review, presenting them as the views of unnamed “eminent” scientists.” Reason’ Magazine, January 1992 Acid Test: Edward Krug Flunks Political..
The most interesting quote?
“One NAPAP scientist, who for obvious reasons wishes to remain anonymous, warns that in the future the EPA will not go through the pretense of research and debate: “There is no NAPAP for global warming.”
Acid Rain and the uncontrollable NAPAP scientists is why EPA outsourced climate to IPCC.

A paper that deserves perhaps a post here is “Science, Policy, and Acid Rain: Lessons Learned” by Lackey and Blair:
“Appreciate that research budgets follow fear! Successful researchers, especially those operating in the American “free market approach” to deciding what research to fund, are great opportunists when seeking funding: “good news” or “old news” does not result in financial support for research, but fear does! Researchers, especially those dependent on “soft” money are often very effective at marketing their own research priorities and frequently “hang their research on whatever (funding) hook is there.” Elected officials and political appointees are apt to funding.”

whats REAL noticeable is the LACK of reporting on it here in Aus.
almost every CO2 and anything humans do item from any aussie uni hits the headlines…
but then, this doesnt fit the green juLiars agenda or the controlled press.

The Palm Beach Post, Jan 8, 1986
“There is some scientific consensus that acid rain has destroyed life in some freshwater lakes and streams, particularly in the northeastern US and Canada and has damaged buildings and other structures. ……..
Just to mke this clear: in the study it was stated:
“The study showed that terrestrial vegetation accounts for 90 percent of annual formic acid production.”
Formic acid is measured in ppt-s SO2 is ususlly observed in the ppb-scale. And SO2 is just one of the anorganic pullutants acidifying our atmosphere.
Guess what makes the atmosphere more acidic?

Presumably, formic acid is an insignificant contributor to acid rain (as suggested by MFKBoulder above), which is mostly sulfuric and nitric acid. Sulfuric acid comes mainly from buring sulfur-containing coal. So, scientists have been surprised by the source of formic acid, which is not a significant contributor to acid rain. Acid rain has been reduced by “scrubbers” on the stacks of coal-fired power plants so it is not as serious as it once was. Reduction of acid rain by the cap and trade program successfully applied market forces to reduce this form of pollution.

wayne Job, gum trees are not bullet proof. We did a live fire shoot in the late 1980s on a range that was covered in gum trees. We were supposed to be shooting at pop-up targets, but I noticed the bloke lying next to me was putting all his rounds into the base of a gum tree. It took about 30 rounds from his SLR, but he managed to chop it down. I was on the M60 – I gave another tree the better part of a belt and down it came.
Our RSM noticed what I was up to, and he walked over and booted me in the arse, yelling at me to engage the targets and not the trees. The difference was that I was firing 1 in 5 tracer, and the tracer gave me away.
When we finished the shoot, the thick scrub and undergrowth had been totally cleared (like a herd of hungry elk had been through), and several gum trees had gone horizontal.
My data from field observations trumps your model!

Another of the Greenie Undead Lies. Acid rain was localized in the downwind of farms using fertilizer and growing swine, etc. It turned out to have little or nothing to do with combustion products.

There are some reactions where the increase of NH3 in the atmosphere might result in Oxidation of So2 to SO3 (and thus reluting in acidification). Although NH3 (for fertilizer and manure) is per se decrasing the pH of rain (and thus the acidity).
What you did not see is: for the Oxidation of SO2, SO2 must be in the atmosphere; same is true for Nitrogen oxides.
Talking about manure: So not a greenie lie, rather BS on your side.

Greenie Lie is a tautology. Thanks MFKB, I’d rather go with Ferdinand Engelbeen and Pat Moffitt on this one.
