More words on the topic first presented here: http://icecap.us/images/uploads/FlaticecoreCO2.pdf
I wrote:
It appears from this graph that CO2 concentrations follows temperature with approx 6-9 months. The interesting part is off course that the CO2 trends so markedly responds to temperature changes.
To some, this is “not possible” as we normally see a very smooth rise on CO2 curves. However, the difference in CO2 rise from year to year is quite different from warm to cold years, and as shown differences are closely dependent on global temperatures. Take a closer look:
For this writing I have slightly modified the presentation of UAH data vs. Mauna Loa data:
The relatively rough relationship between CO2 growth per year and global temperatures (UAH) is:
1979: CO2 growth (ppm/year) = 3,5 * Temp.anomaly(K) + 0,7
2008: CO2 growth (ppm/year) = 3,5 * Temp.anomaly(K) + 1,2
1979-2008:
CO2 growth (ppm/year) = 3,5 * Temp.anomaly(K) + 0,95
For 2007, a UAH temperature anomaly approximately – 0,32 K should lead to CO2 rise/year = 0 , that is, CO2-stagnation.
These equations are useful for overall understanding, but so far they don’t give a fully precise and nuanced picture, of course. On the graph, I have illustrated that there is a longer trend difference between CO2 and Temperature. Thus, the “constant” of the equation should be a variable as it varies with time (1979: 0,7 2008: 1,2).
The trend difference means, that from 1979 to 2008 the CO2-rise per year compared to the global temperatures has fallen 0,5 ppm/year, or the other way around: It now takes approx. +0,15 K global temperature anomaly more to achieve the same level of CO2 rise/year as it did in 1979.
How can this be? The CO2 rise/year now takes higher temperatures to achieve?
With the human emissions rising in the time interval 1979-2008, one could imagine that it would be the other way around, that CO2 rises came with still smaller temperature rises needed. But no, its becoming “harder and harder” to make CO2 rise in the atmosphere.
So generally, the human emissions effect appears inferior to other effects in this context at least.
Which effects could hold CO2 rise/year down as we see?
The fact that we today have higher CO2 concentration in the atmosphere than in 1979 does not favour more CO2 release from the oceans. However the fact that we approx 500 million years ago had several thousand ppm CO2 in the atmosphere implies that the 385 ppm today hardly does a big difference.
My guess is, that what we see is mainly the effect of the growing biosphere.
In short: A period with higher temperatures leads to higher CO2 rises/year and thus of course after some years higher CO2 concentration in the atmosphere.
In the period of rising temperatures and CO2 concentration, the biosphere has grown extremely much.
The results of trend analyses of time series over the Sahel region of seasonally integrated NDVI using NOAA AVHRR NDVI-data from 1982 to 1999:
Source: http://www.eoearth.org/article/Greening_of_the_Sahel
Even if we put every European in “Plant a tree”-projects we could never reach a fraction of what mother nature has achieved in Sahel alone over these few years. In Addition, in these areas lots of more precipitation is occurring now. ( If we here have a “point of no return” im not sure Africans would ever want to come back to “normal”. We Europeans want so much to help Africans – but take away the CO2? What kind of help is that? )
In addition, the seas are much more crowded with life, plankton etc.
The biosphere is blooming due to CO2: http://wattsupwiththat.com/2008/06/08/surprise-earths-biosphere-is-booming-co2-the-cause/
So today we have a larger biosphere. Every single extra plant or plankton cell will demand its share of CO2. It takes more CO2 to feed a larger biosphere. More CO2 is pulled out of the atmosphere today than earlier. An enormous negative feedback on CO2 levels. Roughly: Any human CO2-influence would cause bigger biosphere that eventually omits the human CO2-influence.
A rather interesting scenario: What happens if temperatures go down below approx – 0,3 K UAH??
Well first it appears from my rough equation that CO2 levels will go down. We will have negative CO2 rise / year. But the bigger biosphere is still there (!!!) even though temperature and thus CO2 levels suddenly should drop and it will still demand its bigger share of CO2. And more, in these days of Cold PDO and especially more precipitation due to the solar condition, we might see more CO2 washed faster out of the atmosphere.
This adds up to my belief, that a cooling after a longer warming trend, mostly due to the bigger biosphere, could be accompanied by quite rapid fall in CO2 levels. Faster that temperature raise leads to CO2 rise? In short, I postulate: CO2 often falls quicker than it rises:
(I am very aware that the data Ernst-Georg Beck has gathered has had a lot of critic. I will not here be a judge, but I think its fair to show that Becks data to some degree matches my expectations, even though the level of CO2 appears high. But I am no judge of what is too high etc.)
So what to expect now? First of all, how about the present cooling??
We should be able to see the big Jan 2008 dive in global temperature in CO2? Well yes, this dive should 6-9 months appear thereafter. And if we take a look at Mauna Loa data released Aug 3, nicely in the 6-9 months time frame after Jan 2008, we saw a dive.
However, this dive was mostly removed from Mauna Loa data 4 Aug 2008, so its hard to judge anything about 2008.
Antarctic ice core data shows that in the period 1890-1940 there was a flat development approx 8 ppm from 300 ppm to 308 ppm.
We have seen first in this writing, that the CO2 is very responsive to temperature changes 1979-2008. So how come the warmer temperatures 1920-40´s has no effect at all on the extremely straight Antarctic CO2 curve?
Is there a mismatch between extremely flat Antarctic CO2 data on one side and Mauna Loa data/UAH data on the other side? If so, which data sets are correct? Mauna Loa/UAH or Antarctic ice cores?






The best comparison is yet to come. AIRS hopefully will be able to depict the swirling globby mass of CO2 changes in time comparison with the swirling globby satellite temperature changes. We will also hope that 5 years does not a trend make with that comparison. But what the hey, if we can bail out poorly run businesses who send money to our campaign coffers (gee thanks Bush), we can throw money at green businesses who send money to our campaign coffers (gee thanks Obama). Serious scientific study devoid of bias be damned.
Astounding.
I rejoice in seeing Jaworowski’s claims getting confirmed so easily. The flat-line CO2 reconstructions from ice-cores are indeed smoothed and weakened signals, for the firn takes hundreds if not thousands of years to close.
Eye balling these charts I would say the first derivative of CO2 correlates pretty good with tropical temperatures and ENSO 3.4.
Jeff Wiita-
Europeans often use commas where Americans use decimal points, so the numbers are 3.5 and 0.7 (Americanized).
K refers to degrees Kelvin.
Question to you all!
I am wondering about the gas concentration of Air. I understand that CO2 is emitted somewhere and think that the CO2 concentration then is locally higher.
But how does it mix with the other gases which are in the Air?
What does wind do? Does it blow heavy gases around?
Where do we measure the CO2 concentration and is that reprensentative?
Is the CO2 concentration higher in the Rockies on top or higher in the valleys?
I would assume that there is no worldwide identical concentration!
We have local hotspots (generators) and probably low spots (rain forests)
Looking forward to some more insight,

@Williem de Rode
You write
” Only around 1998 there is a coincidence between the two parameters.”
“If there would be a relationship then the plot of the one parameter agains the other would show some trend.”
Im not sure I follow you quite. You have made some plots not showing a common trend? Could you provide link for these?
The common trend between CO2rise/year and Global temperatures does rise the question of causality. Which is the case:
1) The CO2 rise/year leads to temperature rise?
2) The temperature leads to CO2 rise/year?
3) Both parameters are caused by a third influence (the sun etc.)
1: This scenario could easily be confused with the normal greenhouse gas thoughts: More CO2 leads to higher temperatures. But don’t make that mistake. CO2 rise /YEAR is a totally different story than total CO2 conc.
The greenhouse effect of CO2 is described as coming very graduate, as a logarithmic function of the entire CO2 concentration. A greenhouse effect corresponding to a rise in concentration/year has never been reported. Thus to believe in scenario 1) is not reflecting any known behavior of a greenhouse gas. It demands a new discovery of greenhouse gas physics.
This I believe leaves us with possible scenario 2 and 3.
There is some noise on the graphs, but if there should be any doubt about causality (I think not), yes, the year 1998 do provide us with a signal so strong that it lifts far beyond the noise level, and tells a clear story.
But never mind which of the 3 scenarios is correct: If there is a common trend between CO2/rise per year and global temperatures, then there is a severe problem for the extreemly flat Antarctic curves. Because the temperature curves are not that flat. For 1000´nds of years we should have had CO2 concentrations between 280ppm and 290ppm.
And the ratio CO2ppmrise/year = 3,5*temp(K) + const, makes it virtually impossible.
Notwithstanding the scientific evidence, this one will be a bitter pill to swallow by the naive environmentalists and watermelons (green on the outside, red on the inside) of this world: the notion that the biosphere is blooming goes against their emotional deep beliefs, risk shattering their whole raison d’être. You will thus, as with any cult, see a remodeling of their message, part denial, part adaptation, to explain why apocalypse did not happen, and why it is only but postponed, still very near to come.
And considering the influences of institutionalized mysticism (various organized religions, cults, etc) on human life’s organization, such human phenomenon should not be discounted.
@Nylo
Yes i could have used other temperature graphs etc, and i have indeed seen some similar graphs using GISS or RSS, practically same result.
But your Ocean temperature graph might be interesting, can you bring a link?
gary gulrud (05:30:19) :
Unlike Beck’s data where CO2 is measured directly, CDIC at Mauna Loa dessicates the air by means of H2SO4 before measuring via IR. Beck’s work indicates this systematically understates CO2 by 20ppm.
Actually they don’t!
Determinations of CO2 are made by using a Siemens Ultramat 3 nondispersive infrared gas analyzer with a water vapor freeze trap. This analyzer registers the concentration of CO2 in a stream of air flowing at ~0.5 L/min. Every 30 minutes, the flow is replaced by a stream of calibrating gas or “working reference gas”.
Thank You Scott
@richard Hill
“You mention an early result of a Mauna Load downtick in August 08..”
The corrections right or wrong does to me lead to some uncertainty how to use results of that year. The dip this year was not at all small. Are you sure they make corrections of that size every year?
@Allan M R MacRae
Thankyou for a very nice summary of this subject!
I have also seen it commented by John Daly when he lived.
You quote from “Cynthia Kuo, Craig Lindberg & David J. Thomson” :
“The results confirm that … temperature and atmospheric carbon dioxide are significantly correlated over the past thirty years. Changes in carbon dioxide content lag those in temperature by five months.”
Yes, and maybe we need to take these correlations a step further?!?
And merry christmas to you!!
@Georg Hoffmann
You seem to have “seen the light”. Please explain how come we can have 1000 years of non-changing CO2 levels when temperatures and CO2rise/year appears to be strongly correlated.
If you judge my writing as crap, could you bring the answer?
If not, take a look at the Beck graph of actual measurements from my writing.
You mention that in the seventies Sahel lost biomass. Yes but from what level? If there is just a little bit of truth I Becks graph, the seventies CO2 levels where far below 1940´ies. There fore Biomas decrease is not surpricing.
It was colder in the seventies. Don’t forget, it was in the 70´ies that many scientist claimed an iceage to be emerging. This they did because of cooling.
Pinatubo was quite conducive to better plant absorption of CO2 v.v. diffuse light, causing the CO2 dip. See paper I think by Nasa. Opposed Chicon spitted quite a different mix. Temp and CO2 lagging or leading? There’s a 12 month cycle, and it continues to be up. 386.20 was the latest trend figure… and all in those years of global cooling, but only if charts are chopped off showing only after 1.1.2001.
… the 385 ppm today hardly does a big difference.
What were the global temps 500-600 million years ago in an utterly different continental configuration? What was the ozone level back then in the stratosphere… was it conducive to allow live on land?
@Bill Illis
Your graph is very interesting!
Remember the difference in trend from 1979-2008? It showed that in 2008 the same temperature led to 0,5 ppm CO2 rise/year less than in 1979. I suggested, that this was mainly due to bigger biosphere. If so, the difference to some degree reflect size of biomass:
The higher the CO2 rise/year trend is compared to Temperature trend, the smaller biosphere.
The lower the CO2 rise/year trend is compared to Temperature trend, the bigger biosphere.
Bill, you graph thus indicates big biosphere on a falling trend around 1958. The falling trend in biosphere seems to continue to late 1970íes (?). Thereafter the biosphere grows again.
Becks data – unlike Antarctic data – reflects that, we should have had a bigger CO2 levels around 1940. If its true that more CO2 leads to bigger biosphere it definitely makes sense that 1958 shows a bigger biosphere in a falling trend.

It wasn’t too long ago when the prevailing science belief was that a melting Arctic would stall the Atlantic current by freshening it and thus cause a deep freeze in the northern hemisphere. That was in what, 2003? But the current didn’t stall and yet we are in a deep freeze. So much for prevailing scientific belief.
My revies of these comments indicates that Mauna Loa is considered to be the sole source of volcanic out-gases (VOG). Kilauea is just south of there and has been continuously erupting for 30 + years. Whenever the trade wins stop blowing, the Kona (southery) wind blows. The Kona wind causes VOG to inundate the Big Island and other islands when prolonged. Kilauea is an intermittent source of CO2 emissions that will corrupt the data gathered at Mauna Loa. I am not aware of any explanation as to if and how the Mauna Loa data is adjusted to offset the Kilauea VOG.
Does any one know?
There are 3 sites from which CO2 data is readily available.
Mauna Loa, Barrow Alaska, and the South Pole Station.
You couldn’t ask for more widely separated sites. They all show essentially the same results with some seasonal variations which are to be expected.
http://tamino.wordpress.com/2008/08/07/a-brief-tale-of-three-sites/
So the intimations that volcanic activity has hurt the integrity of the data don’t seem correct.
This would also show that variations in CO2 concentrations due to local factors are not affecting these measurements.
As far as tracking CO2 regionally, there are satellites that do that. They show the sources and sinks of CO2 world wide. All the red shows up in populated areas like the NE US etc.
http://wattsupwiththat.com/2008/09/29/comments-thread-airs-team-satellite-co2-paper-published/
Paleo climate studies have shown that GHG’s from volcanic eruptions in Siberia 250M ybp caused global warming, and the domination of sulfide producing bacteria that lead to extinctions. This happened over millions of years. There is no evidence of a self correcting mechanism in this case.

for a map:
http://weather.unisys.com/surface/sst.html
Maybe if you look around the site there might be global numbers, though from the map it is evident that as far as CO2 goes temperatures in the 30C and temperatures in the -2 at the poles should not be given the same weight without knowing the temperature dependence of CO2 absorption and emission in water.
@David :
You write:
“If the beneficial aspect of CO2 increases in a lineal manner and the warming effect of CO2 decreases logarithmically, then does it not makes sense that at some point CO2 itself becomes a negative feedback?”
The logarithmic relation is a physical proberty, the greenhouse effect as a function of CO2 concentration. This effect is indeed logarithmic. But I this context the focus is on the concentration of CO2 itself – A kind of negative feedback from a CO2-mediated growing biosphere hungry to eat the CO2, pull it out of the atmosphere. A negative feedback not on the effect of CO2 but working to decrease CO2 concentration and thus CO2 effect.
@Jeff Wiita:
You write:
“1979: CO2 growth (ppm/year) = 3,5 * Temp. anomaly (K) + 0,7
What is 3,5?”
The faktor 3,5 is the “best fit” between the correlating graphs of CO2 rise/year and temperature.
K is here like a degree Celcius, a little over 2 Farenheit.
Down to earth: If the global temperatures rise 1 degree Celcius, The CO2 rise per year seems to rise 3,5 ppm faster. That ism the CO2 concentration rises much faster with higher temperatures.
My point is not to describe quantitatively exact correlation as it is not possible. I just want to show, that very valid and respected data right in front of our eyes shows that CO2 varies very easily. This make the extremely flat “official” Antarctic CO2 graph virtually impossible. The would demand toatly constant temperatures for 1000 years.
@Det (08:37:18) :
CO2 concentrations:
– Are slightly higher near the ground than for instance 10 km up in the atmosphere, in the size 10 ppm.
– Are slightly higher in the northern hemisphere than the southern hemispere
– Varies from day to night
– Varies with seasons
– Are measured all over the world. We normaly refer to the Mauna Loa results as this is the longest data series, and Mauna Loa is not that far from the equator and thus to some degree reflects a globe – middle.
“Between 5,000 and 8,000 years ago, both methane and carbon dioxide started an upward trend, unlike during previous interglacial periods,” explains Kutzbach.
http://www.eurekalert.org/pub_releases/2008-12/uow-sde121708.php
According to this guy, the AGW trend (including warming and CO2) is at least 5,000 years old.
I think it’s time to do introduce retroactive carbon taxing, which means we get to tax the bejeezus out of Europe and Asia. lol.
Frank since you are an engineer I assume that you’re familiar with differential equations?
The DE describing the concentration of CO2 is given below (a schematic of Emanuel & Killough’s detailed equation):
d[CO2]/dt=F(t)-Fo([CO2],T,t)-Fb([CO2],T?,t)
Where F is the fossil fuel source term, Fo is the net exchange with the oceans and Fb is the net exchange with the vegetation etc.
How could [CO2] not be a function of T? Also since we are dealing with the difference between large terms why would it not be sensitive to small variations in those terms from year to year?
Modeling Terrestrial Ecosystems in the Global Carbon Cycle With Shifts in Carbon Storage Capacity by Land-Use Change, William R. Emanuel & George G. Killough, Ecology, Vol. 65, No. 3. (Jun., 1984), pp. 970-983.
The grey/blue lines seem to indicate that the rate of temperature increase is faster than the rate of co2 increase. I would expect that if co2 was becoming a less effective forcer, that the slopes would be reversed. That is co2 slope would be > temperature…
E.P.A. Ruling Could Speed Up Approval of Coal Plants
http://www.nytimes.com/2008/12/19/business/19coal.html?_r=2
WASHINGTON — Officials weighing federal applications by utilities to build new coal-fired power plants cannot consider their greenhouse gas output, the head of the Environmental Protection Agency ruled late Thursday. Some environmentalists fear the decision will clear the way for the approval of several such plants in the last days of the Bush administration.
The Supreme Court ruled last year that the agency could regulate carbon dioxide, the most prevalent global warming gas, under existing law. The agency already requires some power plants to track how much carbon dioxide they emit.
But a memorandum issued by Mr. Johnson late Thursday puts the agency on record saying that carbon dioxide is not a pollutant to be regulated when approving power plants. He cited “sound policy considerations.”
“The current concerns over global climate change should not drive E.P.A. into adopting an unworkable policy of requiring emission controls” in these cases, he said.
John Walke, a lawyer at the Natural Resources Defense Council, said in a statement, “It’s a marvel to behold an E.P.A. action that so utterly disdains global warming responsibility and disdains the law at the same time.”
“Actually they don’t!”
Kauffman indicates their protocol does indeed include such dessication, e.g., at:

Your link gives me no clue as to your bona fides as it doesn’t work for me. We have yet to examine the issues with the Siemens black box.

I’ve never been able to figure out; is lol = LOL = Lots Of Luck or is it Laughing Out Loud ? I can’t kee p up with the jargon.
I get confused by AMO and am0 = Air Mass Zero, meaning outside the atmosphere.
But to the EPA refusal to label CO2 as a pollutant. The Supreme Court ruled that EPA “MAY” regulate CO2 as a pollutant; I don’t believe they said EPA must.
Since the ENTIRE rationale on which the case was brought to The Court was solely on the claims of global warming/climate change, and no evidence of CO2 having any other polluting properties (being an absolutely essential constituent of the atmosphere) the ONLY basis on which EPA would be able to regulate CO2 would be on the basis of the climate change/global warming threat; and if they claimed that they would have NO ALTERNATIVE but to hold WATER VAPOR in similar contempt, since it demonstrably has a much greater “greenhouse” effect than CO2 or an or all other GHGs.
So until EPA is ready to regulate water vapor as well, they have no basis for regulating CO2.
And trying to argue that water vapor is innocuous because it is removed from the atmosphere much faster than CO2, doesn’t wash, because if that were true on a climate time scale, then earth would be a frozen ball. The fact that we sit at +15C and not -15 C is definitive proof that water vapor is not removed from the atmosphere fast enough to not have an appreciable global warming /climate change effect.
That of course is all IMHO , but there’s an avalanche of lawyers willing to step up if EPA tries to weasel out of the unavoidable H2O/CO2 linkage. Either both are pollutants to be rergulated or neither is.
By the way, CO2 dissolves readily in H2O and moreso in cold H2O, so every time it rains/snows/etc, a whole lot of CO2 is washed out of the atmosphere.
I’ve read that the reason we don’t have 3000 ppm of CO2 in the atmosphere any more is because during the Cambrian when everything went nuts, there was so much plant growth, it sucked up all the excess CO2. Well I bet I have my Cambrian mixed up with my Permian or some other dinosphere; but you get the idea. All those ancient Kiwi Tree Ferns, is what cleaned up all that CO2 muck.
I’m not against EPA getting into some stringent controls of real pollution that may be associated with coal fired power; enough is known about clean coal that there is no reason for the (US) to put up with the kinds of gunk we used to. The greenies will have my support on that sort of cleanliness, but till they prove their case on CO2 driven climate change/global warming, we will be in disagreement.
If I understand Frank’s thesis, he still finds that warming (the cause) preceeds CO2 increase (the effect), even if only by 5 months.
A five month lag in a feedback loop is a formula for an oscillator; and not any decadal oscillator either.
I’ve never ever seen any climate feedback equation that includes the time dependent response; just a static condition, without any proof that the feedback system is stable. The Jubilee Diamond at 245.35 Carats is a cushion shaped Brilliant cut, that is so perfectly cut, that it can be balanced on its culet, which is less than 2 mm diameter.
But it isn’t in stable equilibrium in that condition. (interesting aside factoid).
But maybe John Walke needs to go and reread the Supreme’s words again. The “existing law” they referred to relates to pollution, so EPA would have to prove pollution.
Hey if I was the Supremes, I would take those Lawyers/plaintiffs money for a frivolous suit also.
The EPA doesn’t have ANY global warming responsibility, because nobody has EVER PROVED that global warming is harmful to the environment, and all the evidence points to it being harmless or even beneficial.
And for a half degree F out of a nearly 150 deg C range, I don’t see how one could come up with any such proof.
But frankly, if the US EPA wants to pursue that, knowing that it would doom the bulk of the world population to permanent poor status (and those Aussies too); well that will make a lot of friends for the US greenies; who after all really want to see homo sapiens sapiens become just another archeological fossil find, by the intelligent termites of a future green planet.
@Jason
The short term variation seems rather conclusive, temperature increase leads to CO2 peak. And the variation is just far too big for the flat Antarctic CO2-curves. The long term trend can have more explanations. Biomass growth is reality, its happening. CO2-forcing on a bigger scale, i dont know, its not provable from the graphs nor disprovable. However, the narrowing in between trends happends both before and after the 1970´ies, See Bills graph. Why do you think that is? (If you believe that the CO2 has been steadily rising the whole century). The difference between the graphs around 1960 equals the difference around the mid 1990´ies. This would make total sense if you accept Becks data to some degree, both as a result of Biomass and perhaps some CO2 forcing.
