How Much of Atmospheric CO2 Increase is Natural?… Natural Variations in CO2 are LARGE… We should remember how much we have anthropomorphized recent warming: Human activities produce CO2 in reasonably well known amounts, humans do the monitoring of CO2, then humans do the modeling. Since we really don’t understand the natural sources and sinks very well — not to the <1% level needed to document that a “natural balance” exists (since human emissions are now close to 5% of natural sources and sinks) — we just assume they are “in balance”. There, problem solved. So, we impose a human explanation on what we observe in nature. A common tendency throughout human history. We are searching for answers at night under the only streetlamp where we can see.
[Update: obviously, I didn’t bother read RS’s article carefully. So I’m grateful to JM for pointing out that RS goes for extra credit by reffing Murry Salby:
I believe that pointing this out is part of the reason why Murray Salby got into trouble recently. The scientific community doesn’t take kindly to some of us suggesting nature itself might be causing “carbon pollution”. Baaad scientist.

WARMING CAUSES CO2 TO RISE, NOT THE OTHER WAY AROUND The rate of rise in atmospheric CO2 is currently 2 ppm/yr, a rate which is 100 times as fast as any time in the 300,000 year Vostok ice core record. And we know our consumption of fossil fuels is emitting CO2 200 times as fast! So, where is the 100x as fast rise in today’s temperature causing this CO2 rise? C’mon people, think.

He’s wanted to believe in natural CO2 fluctuations for a long time. He doesn’t want to either:
a) actually examine or understand the carbon cycle models in any detail, but just hand wave, “well, sure, they _say_ they can explain it, but they are just models, right?”
b) engage with the CO2 ice core record (doesn’t even get a mention, as far as I can tell).
Yeah. “skeptic”, my rear. Contrarian is such a better term. Or the “d” word, but I avoid that, because why spend time arguing about whether it is a holocaust reference (it isn’t) rather than arguing about the actual science.
(once upon a time I drafted a rebuttal to Essenhigh et al., for which I actually did have to dig into understanding the carbon cycle at a slightly more than superficial level. I wanted, but never got around to, make a simple model with all the key bits – Revelle factor, carbon pools for ocean surface, ocean depths, vegetation, annual cycle, and isotopes, so that it would be easy to demonstrate to the carbon contrarians how the standard model explains the observations quite well and it is actually really hard to explain them any other way…)

@MMM Spencers new regression analysis is actually even worse than the 2009 one, in that he performs the regression analysis on the detrended signals and then applies those regression coefficients to the original signals. This assumes that the physical process that causes the interannual variation (the wiggles) is the same one that causes the long term trend. Obviously this isn’t true as otherwise you would get the same set of coefficients by perfoming the regression analysis on the original data.
This is in addition to the fact that a correlation with the growth rate has no mathematical connection whatsoever with the long term trend in atmospheric CO2 http://www.skepticalscience.com/roys_risky_regression.html .

This is little golden nugget:
“The net increase of carbon dioxide both in the ocean and in the atmosphere is unchanged in my 50-50 scenario compared to the consensus 100-0 scenario.
The difference in the 50-50 case is that the ocean has absorbed more of the fossil carbon dioxide from the atmosphere but in the same time emitted more natural carbon dioxide to the atmosphere (this is possible because absorption and emission of carbon dioxide into and out of the ocean are taking place in different locations).”

Is Pehr suggesting a model along the lines of the following:
– anthropogenic CO2 equals +30Gtpa
– natural sinks absorb 30Gtpa
– therefore human emissions cause no CO2 rise
– oceans release 16Gtpa
– observed CO2 increase in atmosphere is 16Gtpa, all of it coming from the ocean

Pehr Björnbom, I stopped commenting because I realized it was futile to get you to understand the mistakes in thinking. Your proposal requires that the ocean takes up a significantly larger fraction of ‘anthropogenic’ CO2 than that it takes up ‘natural’ CO2. That is, it must *know* what CO2 was emitted by fossil fuel burning, and what not. There is an alternative option, but that requires not only that CO2 is not well-mixed, but also that the oceans are compartimentalized very heavily in a horizontal direction with the ocean section directly adjacent to land being the sink, and further out being the source. Which just doesn’t fit with measured reality.
Also, for others it may be useful to see the final decision regarding that idea you put up at Lucia’s:
http://www.earth-syst-dynam-discuss.net/4/25/2013/esdd-4-25-2013-discussion.html
Finally, it may also be helpful for the people here to know that Björnbom has enthusiastically contributed to a Swedish blog called “the climate scam” (recently renamed to “klimatupplysningen”/Stockholms Initiativet). I think the original name says it all about the starting point of Pehr Björnbom in the debate.
Björnbom even recently repeated the false allegation that Salby lost his university job because he contradicted the consensus on the CO2 increase being anthropogenic.
http://www.klimatupplysningen.se/2014/09/12/murry-salbys-paradox-och-de-destruktiva-inslagen-klimatdebatten/
People who paid attention know Salby lost his job by not doing his job, which included teaching obligations. I have absolutely no doubt whatsoever that my university would fire me (KTH would do the same, for that matter), if I decline to teach, get ordered to teach, and then just leave the country and not show up at the teaching I should have performed.
Note also that certain attacks on Salby himself might have come from this kind of manipulation:

1) I looked at ~60 of Salby’s papers from 1989 onward, ~all.
His best-cited work was in the 1990s, and citations really dropped off for anything submitted after ~2001.
There were way more Conflict of Interest problems than NSF detailed. In particular, Salby was always the P.I. For the grants gotten by his shell company ASA, he was generally the corresponding author, and he wrote the final reports to NASA or NSF… but not once did the actual papers give an ASA affiliation, thus hiding the gimmick. The only way to see this was to look at the actual papers (not just abstracts) for the grant Acks, and dig out final reports, which often lagged by years, and in at least one case, needed a FOIA to get. Some papers were claimed for credit against grants in odd ways.
Still he did reasonable science, even if he broke the rules to get more $, until 2011 when he started this bogus CO2 and ice core stuff, not something he’d published on. Almost nobody (except Dikran Marsupial, and maybe a few more) knew thr field well enough to know that an atmospheric circulation expert (which Salby is) is not necessarily a carbon-cycle and ice core expert ( which Salby isn’t: see my review of his book at Amazon. Most if book is fine, about 20 pages is poor.)
2) The cancelled ticket, which the blogosphere interpreted as malice, was almost certainly due to an effect any good systems analyst knows: organizational workflow race condition.
Anyone who looked at MQ’s rules and org charts would know that like most schools, (a) misconduct committee is about as far from the (b) accounting/administration/credit card/airline flow as you can get. There are at least 3 databases (MQ personnel, credit card company, and airline).
(b) would have no clue about the process in (a) which inevitably involves a bunch of administrative people in multiple organizations.
(a) especially low-level folks would not know about scheduled misconduct meetings
The error MQ referred to almost certainly was the procedural hole: Salby’s credit card should have been suspended immediately in Feb 2013, AND someone detailed to track down any outstanding things like not-yet-used tickets… preventing Salby from flying in the first place. The error wasn’t on canceling the ticket, but in not canceling both tickets before he left. But I understand how such happens: this was so weird it would have fallen through cracks: normally people facing misconduct hearings do not buy expensive tickets to be away.
I talked to an airline, 2 VISA folks, and a travel agent, all accustomed to credit card misuses, none of whom had ever seen anything like this with a corporate credit card, and agreement on procedures was nonexistent. Anyway, if you draw the organizational flow graph, there are lots of race conditions, so no surprise. Almost certainly, some administrator finally canceled credit card and eventually the unused ticket, with no clue that Salby was supposed to be back. His schedule must have cut it tight: “stranded” is a strange term for needing to fly from Paris to Sydney. Flights are frequent.
Salby didn’t even have a serious reason to go: he had 2 *posters* at EGU, not orals, the other talks were ~university seminars, easy to cancel.
3) IMHO the worst if all was Salby’s mistreatment of his grad student Titova.
[The “citations falling off after 2001” rather fits in with what I’d kinda thought. That all somewhat fits in with the idea that he just ran out of ideas. So what isn’t really clear is if this has anything to do with the dodginess with the NSF grants, or if that’s to the side.

It didn’t take more than a few minutes to figure out how totally clueless this was, and that Salby’s behavior was (word I wouldn’t use, but among the worst I have heard in mistreatrment of a vulnerable PhD student.)
2) She had already done ozone work in Russia, came to MQ no later than December 2009. By Nov 2010, she was working on an approved dissertation topic on Antartic ozone. She coauthored papers on that with Salby that were published May 2011 and July 2011, and she did internal talks November 2011 and November 2012 … entirely consistent with normal progress. One would expect her to be finishing dissertation.
Not once in Salby’s 2011, 2012 and 203 lectures have I found any mention of her, or words like “our research.”
But in his July 2013 email, “our research” or equivalent suddenly appeared 5 times, and he evinced great concerns for her and fact she couldn’t talk to him.
She was listed as coauthor of his two *poster sessions* at EGU in Vienna in April 2013 .. .but there is no evidence she was really involved. There are only 2 inreprterations:
a) Salby took her away from her dissrtation work to help on an absurd topic far from here own.
b) She had zero to do with them, Salby just added her name as a “human shield” for sympathy.
Either way, he got himself fired, bad enough for a PhD student, but even worse, tried to drag her into his mess, while crying copious crocodile tears of worry for her.
It’s hard to know how MQ could forbid her from talking to him, but a protective order might well forbid him from talking to her…
Of course he’d tried to blame the COI mess with his ASA on his much-junior helper there, so this is nothing new … but I’ve never seen anything quite like this.

I think that he is right saying that such a large uncertainty in climate sensitivity is the same as acknowledging that we don’t know. If the climate sensitivity is at the low end there is no problem, if it is at the high end it could be catastrophic.
I was surprised that John Christy and Kerry Emanuel have so many views in common and both recommend action in the form of expanding nuclear power in USA. But they had different evaluations of the risk. John Christy doesn’t think that there is much risk and that the risk with government actions would be more serious for his grandchildren.
Kerry Emanuel emphasized that there is a small probability for a large catastrophe which means that the risk isn’t negligible. My own risk evaluation is more like Kerry Emanuel’s and he proposes the kind of actions we are already doing in Sweden (Sweden is said by Swedish politicians to have the highest carbon tax in the world). Sweden’s electricity production is almost fossil free. Sweden has rather low carbon emissions per capita, less than China.

There are some comments on my ESDD paper on “Estimation of the climate feedback parameter by using radiative fluxes from CERES EBAF” in this thread. Since this is a science blog perhaps some of my thoughts on that paper and the interrupted review process is of interest.
Note that this was my first, but not my last, try to publish a geoscientific research work in peer-reviewed scientific literature. Although I was not successful to complete the publication to appear in ESD I have got a useful experience and I have increased my knowledge and understanding in this research field.
There are two important reasons that I decided not to complete the review process.
The first reason is that a new paper by Armour et al. (2013) appeared shortly after I had submitted my paper to ESD. Their results undermine my interpretation of my own results, that is I have to rewrite my paper based on a new theoretical background. Their results suggest to me a fundamentally different interpretation that I have outlined in the following comment:
Click to access esdd-4-C137-2013.pdf
The second reason is that the second referee remarked that the topic of my paper is “politically controversial”. I have myself considered that I worked with a fundamental problem (blue skies research), concerning the relation between the anomalies of the global means of the net TOA radiative flux and the surface temperature. Obviously this is not how others consider the topic of my paper.
I have no intention to work with a politically controversial research topic. From my forty years long research career I have no experience in such things and how a paper on a politically controversial topic is to be correctly written.

Let me conclude the discussion here between me, Marco and Craig Thomas with a short summary.
Our discussion was initiated by my challenging comment over at Roy Spencer on the interpretation of the falling atmospheric O2 mixing ratios:
http://www.drroyspencer.com/2014/08/how-much-of-atmospheric-co2-increase-is-natural/#comment-130499
In that comment I used for my argument a hypothetical case where the increase of the atmospheric CO2 mixing ratio was assumed to be 50% natural and 50% anthropogenic. Both Marco and Craig Thomas have argued that such a hypothetical case is impossible, while I have maintained the opposite view supporting my arguments with references from the scientific literature.
I recommend interested readers to study the whole discussion between me, Marco and Craig Thomas over at Roy Spencer and make their own conclusions.

In fact I admire Murry Salby. This is because I admire good scientific text book writers in general, they are very important for the sustainability and development of Science.
I have read his textbook Murry L. Salby. Fundamentals of Atmospheric Physics, Volume 61 (International Geophysics). Kindle Edition. I have found that he is a very knowledge scientific writer with a good understanding of the topic he is writing on.
That’s also why I wanted to understand what was behind Murry Salby’s statement about his equation describing the rate of increase in the atmospheric carbon dioxide mixing ratio as a function of the global temperature only. This equation is given in the video with his lecture in Germany and therefore it was possible for me to make the calculations to test this equation visa vi data. I used CDIAC carbon dioxide mixing ratio data, both instrumental and according to Law Dome back to the end of the nineteenth century and temperature anomalies from HadCRUT and found that Murry Salby is right.
[What you’ve demonstrated is how pointless replication without understanding is. If you blindly repeat MS’s calculations, you’ll get the same answer. This should be no surprise – no-one is accusing him of faking his calculations. What you’re missing is the pointlessness of his calculations, and hence of your replication -W]
I don’t claim that we can conclude from this result that the increase in atmospheric carbon dioxide in not influenced by anthropogenic emissions. I only claim that Murry Salby in good faith claimed that there is this equation. I also think that he was right to disseminate his result for scientific discussion. This is an interesting result and I also think that his work should have been accepted for publication in order to facilitate the scientific discussion about it. It’s not convenient for the scientific community that such a remarkable result isn’t available in the peer-reviewed scientific literature.
I propose to call this equation Murry Salby’s paradox and from a scientific point of view that paradox should be explained. There are some explanations outlined on climate blogs and I have my own preference. However, all that happened in connection with Murry Salby’s paradox suggests that there are serious problems with the scientific discourse in climate science.

You previously said “This equation is given in the video with his lecture in Germany and therefore it was possible for me to make the calculations to test this equation”.

Indeed you don’t even seem to understand the very concept of why it could – even in theory – be pointless -W]
Neither was my work pointless. My point was to find out if MS did his claim in good faith or not.

Pehr,
I believe you share with me a profession – chemical engineering – although your contribution there far outweighs my own.
Perhaps considering a simple mass balance would help.
First of all emissions:
Then the atmospheric accumulation, measured as concentration.
The correlation is remarkable. No significant change in CO2 for a millennium, then atmospheric concentrations rise lockstep with emissions. Of course, the graph can be further extended back from other ice cores to show the modern rise is unmatched in a million years.
This data can be combined to calculate the airborne fraction:
Only about half (46%) of emissions have ended up in the atmosphere. Far from a temperature rise causing CO2 to be emitted from natural sources, as Salby appears to propose, the exact opposite has happened – the biosphere has acted as a sink for about half of our emissions.
There are other consilient data, but the mass balance alone plainly refutes Salby and makes an irrefutable case for the anthropogenic cause.
The anthropogenic source of the CO2 is as close to a proven fact as it’s possible to get in science. You diminish our joint profession by supporting these claims.

Pehr, a simple request to you, if it is so simple:
Calculate the atmospheric concentration of CO2 during the LIA, around 1650 or so. About 1.2-1.3 degrees colder than today. Then do the same for the most recent ice age (about 5-6 degrees colder than today). Subsequently explain how Salby’s conclusion (CO2 *levels* are set by temperature) must by necessity no longer hold if we go slightly outside the temperature envelope of the last 60-or-so years.
That’s another thing any graduate student in climate science would be able to do. They are also likely to be able to read a graph, and as such argue that in the IPCC figure you would have to change *more than two* numbers. After all, if you make the pre-industrial ocean outgassing 2 PgC/y larger, you would have to make one of the uptake mechanisms (and that can’t be the ocean) also 2 PgC/y larger. Otherwise the rate of increase in atmospheric CO2 would already have been about 1-2 ppm/y pre-industrial.

“Why is Salby so confused? Why does he fall for such an obvious error? Why does he persist in that error when many other people have clearly explained it? ”
I’m not sure anybody really knows. We do know some facts:
1) Salby is an atmospheric physicist, not a carbon-cycle expert or a paleoclimate researcher. Salby specialized in atmospheric circulation, waves, oscillations,etc.
2) See my review of his 2012 book. Most of the book is fine: lots of differential equations, like you’d expect of fluid mechanics … plus about 20 scattered pages of nonsense outside Salby;s expertise.
See the Preface: Salby doesn’t think much of climate science beyond his own specialties, so of course he doesn’t listen to anyone.
3) From his history, he clearly thought he was smarter than anyone around, and he actually set up the shell companies pretty well and got away with it for years. Of course, when they started closing in on him, he had to run to Australia.
(If anyone hears of a public appearance in US, let me know ASAP!)
4) Salby seemed to have a serious chip-on-shoulder problem:
a) Fights with Webster and CU in late 1990s.
b) Multiple lawsuits vs CU, including one that got the judge pretty irritated, to the point he was going to make Salby pay CU’s costs.
c) Lawsuit against State of Colorado.
None of these cases went very well, and then of course, his method of going after MQ by sending emails to bloggers seems … very strange, especially given his history, which was awfully easy to find. Generally, long-tenured full professors rarely suddenly depart (mid-year) from schools strong in their discipline and (in this case) near NCAR and NOAA, useful for collaborations. Although there are plausible reasons for such moves, they are rare. That was a big flag. I’d seen Salby’s stuff in 2011, knew it was silly, saw John N-G’s amusing comments at Real Climate on Salby’s talk, and then ignored it until this popped up in 2013. I knew about many problems within half an hour, but though it might be fun to let the blogosphere froth at the mouth for a few days, and it responded well. 🙂

That his ideas on the carbon cycle don’t withstand scrutiny, and that people point this out, is not a smear campaign. That Salby himself and so many others claimed he was fired because of those ideas *are* a smear campaign.

Pehr Björnbom There is no Salby paradox, unfortunately his analysis is simply faulty. He looks at the correlation between the atmospheric growth rate and “surface conditions” (temperature and soil moisture IIRC). However, the atmospheric growth rate is obtained by differencing the atmospheric concentration, which means that the long term trend in atmospheric CO2 becomes a constant offset on the growth rate. Correllations are completely insensitive to additive constants on either of the signals over which they are evaluated, which means that a correllation between growth rate and temperature has no mathematical connection whatsoever with the long term rise. Of course you can repeat Prof. Salby’s analysis, but that doesn’t mean it is meaningful. I wrote a blog post on this at SkepticalScience, which you can find here:

You will find that the equation displayed by Salby in the video, describing the rate of change of the carbon dioxide mixing ratio as a function only of the temperature anomaly, in fact quite well describes the observations according to the Keeling curve and the Law Dome ice core data.
As I write in the discussion, if this would be possible to explain as a true effect of a real physical mechanism it would challenge the consensus that the carbon dioxide increase is anthropogenic. However, if this instead can be explained as an artifact it is justified to call it Murry Salby’s paradox.
I think that this is in fact a paradox and I have a preferred explanation how this paradox is arising, although I don’t want to mention it now and here.

To potentially spare some peoples time…
Björnbom’s “replication” has already been explicitly shown to be nonsense more than a year ago: http://uppsalainitiativet.blogspot.se/2013/07/bjornbom-bommar-igen.html
One typical characteristic of pseudo-science is that it goes around and around and around…. but never make any real progress.

But Pehr, if the 15Gt/year rise in atmospheric CO2 has no anthropogenic cause,
– where is the 26Gt/year that is released by humans going?
– where is the 15Gt/year coming from?

Craig, Pehr Björnbom has already tried to explain that elsewhere: you just change one number in the carbon cycle.
Of course, he still doesn’t realise that he is then arguing that CO2 was declining at around 2 ppm/y pre-industrially…

Craig Thomas #91,
My comment #89 was a reply to Dr. Gavin Cawley’s comment #88. My last sentence was:
“I think that this is in fact a paradox and I have a preferred explanation how this paradox is arising, although I don’t want to mention it now and here.”
This statement was meant to tell the readers that I think that the increase of the carbon dioxide in the atmosphere is influenced by human carbon dioxide emissions. That is the reason that I call Dr. Murry Salby’s finding Murry Salby’s paradox. His finding appears to show that there is no anthropogenic cause of the carbon dioxide increase but this may be an artifact and it is possible to explain how this paradox arises.
It seems to me that your questions to me are irrelevant in this context considering that you are implying that the carbon dioxide increase has no anthropogenic cause.
