IT IS technology vital to the Government’s hopes of cutting greenhouse emissions from Australia’s huge coal-fired power stations: capturing carbon dioxide from the polluting stations and burying it deep underground.
Australia’s first trial of geosequestration in the Otways reached its first milestone last week — 10,000 tonnes of carbon dioxide was successfully stored two kilometres underground in a depleted natural gas field.
Scientists from the Co-operative Research Centre for Greenhouse Gas Technologies hope to increase that to 100,000 tonnes next year, while continuing to monitor the local geology.
The centre’s chief executive, Dr Peter Cook, who is overseeing the $40 million project, is confident that the day will come when much of the carbon dioxide produced from large industrial sources can be buried.
See the complete article here in Australia’s The Age.
Ok here is my question: What about the long term effects of such a thing? One of the biggest complaints about radioactive hazardous waste disposal is that there is no confidence in predictions of long term stability of the burial site.
Take for example water, how do we know that this formation won’t become water saturated, and that the water will dissolve CO2 into the water and carry it elsewhere only to be released into the atmosphere again? Or how do we know that the system won’t vent the CO2 back to the surface gradually due to displacement or other geologic action?
I’ll point out that CO2 is a heck of a lot more reactive and soluble than glass encapsulated nuclear waste, yet nobody seems to think a thing about it.
In my opinion, the premise of CO2 burial seems absurd not only because of the lack of supporting evidence for certain climate change, but also due to it’s lack of foresight as to the effects of the burial scheme.
JA: “The point is, there shouldn’t be a need for adjustments if the siting standards were followed in the first place.”
JM: It is very difficult to do such things perfectly – there will always be problems, as a practical matter.
It can be done and is being done.
The NOAA/CRN system covering the US is just such a system. Well sited (with photographs, no SHAP), automatic transmission of data hourly (No FILENET), Well distributed (no grid weighting).
All data to be raw and collected not by man but by machine. And to be run in tandem with the old system for a while by way of comparison.
Unfortunately this will only cover the US.
Here is a 2005 NASA appraisal of cloud cover by NASA (Modis and Aqua):
http://enso.larc.nasa.gov/ceres/pub/conference/Minnis.SPIE.05.pdf
In short, it translates to; “We no like what we seeing . We get back to you later, yes-no?”
(Marohasy briefly comments on this in her article.)
“It is very difficult to do such things perfectly – there will always be problems, as a practical matter.”
The experimenter is allowed to make corrections for his equipment but must document this carefully in his protocol. Hansen is not the indicated experimenter.
While seeming specious this explanation is sickeningly tendentious.
Brendan H:
<blockquote”…the recent satellite data show continuing warming in this decade.”
You may be able to get away with completely false statements like that on the political sites RealClimate or TreeHugger. But not here. Click.
Consensus may well be important in applied science (medicine, engineering, et al.); but open and complete information is crucial in pure research.
Kuhn emphasized, in its practice, that these scientists were comprised, at the forefront, of those understanding the current paradigm, its heuristics, classic experiments, experimental ethics, etc., and could proceed to develop hypotheses to test the paradigm at its vulnerable points. They needn’t even be aware of other’s articulated beliefs apart from these elements.
It remained then for a secondary group, to use the former’s protocols to reproduce their results.
Consensus is only a byproduct, the process is what is important. Kuhn even declined to say that progress was a definable outcome of the process.
Jeez: “Please try and see the bias in the wikepedia article.”
The wiki article appends this note to the graph: “In the above figure, there is still a significant discrepancy between the very earliest satellite measurements and the ground based measurements at that time. For this reason only the interval 1982-2005 was used in calculating each trend. ..The origin of this discrepancy is unclear.”
That seems to be a reasonable explanation. Apparent discrepancies should be treated with caution. The same applies to outliers such as 1998 and the current drop in temperatures. The bigger picture is the trend, not individual discrepancies.
Jeff Alberts: “You’re assuming they even know about the microsite violations, or even care.”
I can’t answer that question. From memory, the ‘other side’ dismisses photographs as sufficient evidence of corrupted data and demands numbers. Of course the measuring instruments should be the best possible, and let’s hope the agency responsible raises its game. But uncertain data is better than no data.
Smokey: “You may be able to get away with completely false statements like that on the political sites…”
Not sure which sites you are referring to, but here’s an interesting discussion by someone who seems to know what he is talking about, and the general view from the various studies cited is for a satellite warming trend this decade.

Brendan H:
No it is not reasonable, nor is it reasonable to not include data to the current 3 month period in such a topical piece. The period chosen is simply to imply a trend that is not there.
It is well documented that Wikipedia has been hiijacked by pogies on AGW issues.

O.k. That’s just pure stupid.
One day there will be nanontech robotic microbes who will create diamonds out of CO2 and sunshine, then we can get on with our overdue ice age.

Uncertain data is garbage. Which is what you get when you try to use it.
Evan Jones: “As for the lack of positive vapor feedback, see:…”
I am hesitant in using the vapor data since information on vapor content is one of the least understood variable which is very difficult to measure even with reasonable accuracy. If I am quoting correctly, the accuracy (or reliability) of vapor measurements could be as low as 25 to 30 % (I can look around for reference on some quantitative value) – it is highly time dependent (as well as on altitude and position)- now you see it and now you don’t (since the residence time is relatively short) and seems like you have to catch it at the right time. We may be underestimating vapor content – but we do not know enough to make a concrete determination one way or other. Pofarmer’s comment may be applicable here:
Pofarmer (05:02:05):quoting someone “”But uncertain data is better than no data.”” replied “O.k. That’s just pure stupid.”

The overall trend is up, there is a dip from early – 2007 to now, but that does not appear to be any different that the reductions we observe in the past. I think we will have to wait several more years to see whether there is a downward trend, or it is just a short time phenomenon. I sincerely doubt there is a real change in trend, but I could be wrong. We will see.

Evan Jones: (JM It is very difficult to do such things perfectly – there will always be problems, as a practical matter.)
“It can be done and is being done. The NOAA/CRN system covering the US is just such a system. Well sited (with photographs, no SHAP), automatic transmission of data hourly (No FILENET), Well distributed (no grid weighting).”
I am not really sure. For one thing they will have to do some averaging to go from data collected from 150 or so stations to an average U.S. temperature – they could use simple arithmetic average, then it will be an average of all the readings not really the average for the U.S., they could use an average scaling with the area a station covers, or they could use some function to interpolate temperature between stations and then average. In any way, a certain degree of manipulation has to be done from the raw data to be the final product.
Also if any of these stations are destroyed by flood, tornado, or when new stations come online, corrections are needed. For example Florida does not even have a working site, and only two at the end of this project to represent that large area. In 50 years these sites may not be as pristine as we have now (I assume all the sites we criticize now were started as good sites using the state of the art technology at that time, some of them may not measure up our standards now – this of course belongs Watt’s department). So, I am sure they already apply or will have to apply corrections. Now I agree with Gary Gulrud’s comment that relevant details of those corrections should be available to the public. It goes without saying that the probability of finding errors in their procedure (up or down) will be much higher if more people look at it. It will also increase the credibility of such corrections.
Gary Gulrud: “The experimenter is allowed to make corrections for his equipment but must document this carefully in his protocol. Hansen is not the indicated experimenter”
I somewhat agree with that comment. Hansen did publish a paper summarizing the logic and procedures for his corrections (I can check and post it if you don’t have it, but probably not detailed enough to reproduce the exact code), also I thought he released the code under pressure from McIntyre? Didn’t he? I didn’t keep up with all that. But at the end of the day, since all four temperature plots agree reasonably well (as much as we can expect, under all these statistical variables involved), I do not have as much suspicion on Hansen’s correction as many of his critics have expressed during these years. But I think, if he hasn’t already done so, he should release more information about his adjustments.
Gary Gulrud: “Consensus may well be important in applied science (medicine, engineering, et al.); but open and complete information is crucial in pure research.”
I agree with what you say, but I don’t see a distinction between the first and second clause. When I used the word “consensus” it is not like a group of people after a meeting deciding to have Chinese food for lunch vs. Mexican food. The consensus in science is based on knowing an appropriate level of relevant facts to reach that conclusion. I just am hesitant to stress the need to know COMPLETE information, because there is no end for something to be complete, we can always add more. I do not disagree with Kuhn at all, in his two books I do not think he addressed the issue of consensus in science. My view of consensus is one that is based on the required knowledge on the phenomenon on which they are developing a consensus.
Brendan H. has a point, that AGW critics in the past used uncorrected satellite data to discredit ground station measurements to show that AGW is not true and there is no warming. I think the group at Remote Sensing Systems helped to apply many of the corrections. It is unfortunate that Spencer/Christy data without corrections (sensor temperature, drift etc) was used by some to criticize AGW, it created some level of distrust (the corrections to the pattern they predicted were more significant that Hansen’s Y2K correction). RSS is still trying to understand the need/effect for corrections (eg. Mears, C. A., Wentz, F. J., The Effect of Drifting Measurement Time on Satellite-Derived Lower Tropospheric Temperature, Science, 309, 1548-1551, 2005).
Sorry, we were supposed to discuss carbon sequestration and we diluted that with all these other things.
John McL
Yes, humidity is variable. But it IS measured as drier, and the temperatures have flattened and now seem to be headed south. We’ll see if that trend continues and can be confirmed.
That’s the same sea level link I made, but with inverse barometer applied. It shows the same thing. If you take the trend from 2005 you still get a downward trend, though it’s even more pronounced from 2006. Bigger than the other blips.

Since I am talking about what happened after 2005, a 2005 Maldives ref is not pertinent. (And, as you know, Morner went ballistic over that Maldives report.)
I am not really sure.
The new CRN looks quite good. They have, by all accounts, gridded it quite well, with a simple average in mind. They are good, clean, well sited, automated stations. We’ll have to see, of course, when they go on line this Fall. The Rev has had good things to say about it (so far).
BTW, the oil reserves as of 1975 included shales and tars.
The 3 bil. barrel estimate for Bakken of USGS is “currently recoerable”, which is of use to industry but in no way even vaguely indicates what will wind up being taken out. Note that their current estimate is twenty times more than their estimate just a few years back!
It’s like asking the aluminum industry how many years of bauxite they have blocked out. They’ll tell you under ten years. But you can bet your bottom dollar that we won’t be out of (or even vaguely short of) aluminum in ten years. That was the exact error the Club of Rome made.
Brendan H. has a point, that AGW critics in the past used uncorrected satellite data to discredit ground station measurements to show that AGW is not true and there is no warming.
Yes. And the error (satellite drift) was pointed out, corrected, and the new interpretation is applied. All arguments are now made using corrected data.
Would that NASA and NOAA did the same thing!
For Bakken, put me down for 400 bil. barrels before we’re finally done. (And I may be wildly pessimistic, here.)
“I do not disagree with Kuhn at all, in his two books I do not think he addressed the issue of consensus in science.”
Scientific revolutions over turn consensus, prima facie. If I were writing such a book I might consider it given that consensus is irrelevant.
Another example that one might object with is competition. Cutthroat competition exists in any ‘hot’ field such that Europeans do not cite Americans for prior discovery and doubtless vise versa.
Your point is a non sequiter, consensus can be important in your field, but without an MD/PhD and post Doc with a top PI you have no background in pure research, the target of our discussion. Therefore abstract allusions to experience are unpersuasive.
You will need to be specific and use an accepted framework, Kuhn, to make your point that consensus is necessary to the research endeavor.
Evan Jones: “As for the lack of positive vapor feedback, see:…”
This is what NOAA has to say.
http://lwf.ncdc.noaa.gov/oa/climate/gases.html
“…we have good atmospheric measurements of other key greenhouse gases such as carbon dioxide and methane, we have poor measurements of global water vapor, so it is not certain by how much atmospheric concentrations have risen in recent decades or centuries, though satellite measurements, combined with balloon data and some in-situ ground measurements indicate generally positive trends in global water vapor.”
Somewhere, and I cannot really track it now, I read the accuracy is only about 30 % or so. This is a problem, unfortunately we have not devoted enough resources and work to develop a tool to measure one the most important feedback mechanism. I hope this will be corrected in the future.
BTW: I do believe knowing something is better than knowing nothing (I was just making a mild joke with my quote in my previous post)
I do not really understand the CRN procedure. If it is purely a geometric grid, that may not represent the real altitude adjusted (also wind adjusted) equivalent stations for obtaining a (or the) U.S. average from a simple arithmetic averaging. Which means some type of modeling must have gone in there in determining the locations. In places like Oregon and Washington, if you travel few miles east (like to Bend Oregon) the temperature can fall substantially. So, I am not sure how they are adjusting for such rapid transitions. At the end I hope it all comes out OK, at least I hope everything will be transparent.
I enjoyed our discussions very much. Keep up your work with a skeptical AGW view. It will keep the other side honest. But I still hope both sides could develop a little more trust and remove all the suspicions about the other groups. We will discuss again sometime in the future.
Gary Gulrud: “..Your point is a non sequiter..”
I assume you are using the strict logical formalism here (if A is true, then B is true, since B is true, therefore A must be true; which may or may not be true). That is why I asked for at least one counter example to show something in science that came about to be a rule (or scientific truth) without consensus. I mentioned statistical thermodynamics, we can add quantum mechanics, string theory, uncertainty principle, Boyle’s law, Maxwell’s law, etc., etc. all of which are in pure science. For example, the uncertainty principle evolved due to the endless discussions between Einstein and Bohr (Bohr had to constantly modify the details even until 1930s), and most of the arguments were simple thought experiments (not real experiments), and it kept evolving until a formulation is reached to a stage that is accepted by most scientists in the field. I don’t know what we call that, if it is not refinements for consensus. Most of the public and many scientists have never seen an atom (atomic force microscope and scanning tunneling microscope are relatively recent developments – and even with that only few people working with those devices really see atoms), but slowly and slowly atomic explanations (especially in chemistry and physical chemistry) became recognized as the fundamental explanation, without even seeing it. It did not happen overnight, it took years of consensus development (based on evidence, of course).
Take for example the continental drift theory: Abraham Ortelius (in 1956 or 1957) initially talked about it, developed more fully by Wegener (in 1912), but widespread recognition of this theory came in 1960 or so, and now progress in geology and evolutionary biology etc is based on the continental drift theory. Since the theory was not established before 1960, even though the theory was later shown to be correct, it was not always used for other investigations, thus diminishing the progress of science. It is the general consensus that made continental drift theory a scientific theory and facilitated further progress based on it, etc. Until someone can point out a concrete counter example, it is difficult to believe otherwise. But if someone could show a good counter example, I will be happy to change my view. Kuhn’s subject is scientific revolutions, or paradigm changes.
“Scientific revolutions over turn consensus, prima facie. If I were writing such a book I might consider it given that consensus is irrelevant”
Please look at some of the scientific revolutions: Replacing Sun for Earth as the center of universe, Gilbert’s work in 1600 that gave the foundation for magnetism and electricity, Isaac Newton’s development of calculus, particle wave duality of subatomic particles, development of quantum mechanics, general theory of relativity, …. .There were skeptics all around when such developments came up, and it took years and years before it really became a theory. It took consensus.
“…but without an MD/PhD and post Doc with a top PI you have no background in pure research, the target of our discussion. Therefore abstract allusions to experience are unpersuasive.”
At some level science, engineering and medicine, all become almost the same. Engineers working in nanotechnology are essentially doing physics and chemistry, medical research involves significant amount of biochemistry, medicinal chemistry, molecular biology, etc. and many with applied training work also in basic sciences (including me, I have Ph.D. students and post-docs). So, such classifications will not always apply, that only Ph.D. in science can have background in science. I understand fully what you are saying, that there must be (and natural to have) accepted guidelines and procedures when medicine or engineering is practiced. Sure. But, I believe there is more.
Jeez: “…nor is it reasonable to not include data to the current 3 month period in such a topical piece. The period chosen is simply to imply a trend that is not there.”
A climate trend is by definition long term. Three months does not a climate trend make.
“It is well documented that Wikipedia has been hiijacked by pogies on AGW issues.”
What is a pogie?
Pofarmer: “But uncertain data is better than no data.
O.k. That’s just pure stupid.”
Let’s see. I’m on a busy city street and want to catch some public transport. I ask the nearest passer-by about bus frequencies and he shrugs his shoulders. The second passer-by tells me that a bus leaves from ‘around here every ten minutes’.
According to you, both answers would be “pure stupid”. But by choosing the uncertain data I would have a much better chance of getting to my destination than you, who would be left on the sidewalk searching in vain for certain data. Before you knew it, a mugger would have sensed your helplessness, and you’d be stranded without a penny.
So at bottom, one must believe the paradigm, even some relation, that one tests is true inorder that the trial be effected? This appears to be the logical consequence of your position.
Consensus is equivalent with collaboration?
Einstein studied with Goldberg inorder that he learn the math necessary to present his intuitions. This is not consensus. Whether the group is a tightly-knit group of trailblazers or or all practitioners everywhere, consensus need require no work at all from the majority.
Consensus precedes paradigm elaboration?
Consensus is a recognition on the part of the scientific community, most of whom are superfluous, or merely replaceable, to the elaboration that is science, that a particular solution is seminal.
The Bohr atom and continental drift examples make my point, the elaboration precedes consensus that the paradigm has moved science forward. Work by members of the community begins at any time after elaboration and consensus need not follow by any predetermined schedule.
“At some level science, engineering and medicine, all become almost the same.”
Pure research is not quid pro quo, which does indeed apply in the case of medicine and engineering. To say at some level they are similar is not an argument that they are not different, and my point is that research science is a process that requires a certain apprenticeship, that research done badly is not science even if it necessarily occurs.
Most of the participants as ‘scientists’ are not essential, their work being accomplished many times over.
“It did not happen overnight, it took years of consensus development (based on evidence, of course).”
The dissonance between your opinion of Kuhn and the specifics you are able to articulate seems not to have leaked through to your conciousness.
The consensus, the conventional wisdom, can be wrong and pure science is the process by which this is revealed. Consensus a raison de etre of science?
Dr. McLondon:
Well, my prejudiced reaction, is that they would say that. Anything that supports them is ironclad and anything that doesn’t is moot.
But the AquaSat was launched precisely to determine atmospheric vapor more accurately. I read somewhere that the main purpose of Aqua was to prove global warming (via feedback loops).
So now I hear one side going, “AHA!” and the other said saying, “…Whaaat? ” and then hastily changing the subject.
Now, don’t get me wrong, I don’t know what the data is going to show in the fullness of time. It’s all very recent. They only launched the thing in 2002. But my instincts as a student of history causes me to place a fair amount of chips on the former bet.
What is a pogie?
Etymology: a contraction of “Anthropogenic”.
Which means some type of modeling must have gone in there in determining the locations.
Yes. The argument they make is that they are relying on their current distribution methodic to determine the appropriate locations.
So there will be some question. But in any case, it will be a system that does not require the adjustment of data from individual sites. And even if it finds a different base level, the delta should be a LOT cleaner than what we currently go by.
It’s one of those cases where we are striving not for perfection, but for advantage.
And (FWIW) we will still have the microwave meeasurements from the satellites as a check-sum.
I’ll give the NOAA the benefit of the doubt when I can (which isn’t too often).
