What are the deniers actually saying?
If 80% of people tell you you are driving towards a precipice, sane people at least slow down. At 97% most would probably stop. When the deniers knit themselves up in arguments about percentages here, and what kinds of scientific papers you include in your analysis, at what level are they actually happy for us all to hurtle onwards, carrying their children with us?

timallard at 23:48 PM on 15 June 2013The last time carbon dioxide concentrations were around 400ppm: a snapshot from Arctic Siberia
"The fact that there exists strong evidence for past major warming and its consequences in both polar regions suggests an interconnectivity between the poles, with the implication that these are effects occurring on a global scale."
Consider that right now the planet increases heat retention daily, radiative forcing, and that the flucuations in CO2 are not affecting this much at all due to it still being a rising value. Because of this the atmosphere is now moving heat north and cold south, and the reverse in the southern hemisphere faster and more directly due-north, due-south over both poles as a result.
Both poles are doing this and indications of this are the late season snow in both Europe and the Midwest at this time. These are not mysterious but a by-product of the atmosphere being a heat-transfer system vainly trying to maintain thermal balance until we remove the cause.
This process is to me what keeps global temperatures from rising at this time, it's like we're using an old-style ice-box to cool the house and once the ice is gone nothing is left to cool the planet, ice melted and permafrost thawed.
Therefore global temperature is not a good short-term indicator, it's not predicitive of what's going on, an example, 30-years ago near Disco Island only dogsleds could be used for 6-months of the year, today hunters use their fishing boats to hunt seal, very few use their sleds anymore. What model predicted this?
Further, observing jetstream paths for many years I noticed that many times the air arriving in the Disco Bay area came from the Tropic of Cancer latitudes in the Pacific, gained latitude as moved east and continued NNE to pass over Disco Bay. This versus the cold-period regime that brought very cold air from the north for especially the three coldest months Jan-Mar. From locals they have observed this from being on average -30C historically to today where it's rare to have below -10C, a +68F/20C rise in average temperature.
This easily explains the loss of sea-ice in this area and it's from new jetstream paths being taken quite often in winter which was not predicted by models, thus my reason for bringing it up. That is to recognize that the atmosphere is doing many north-south pieces of jetstream moving the cold to the equator and heat to the poles, this needs to be included in models, we have a new circulation pattern now, the atmosphere is being driven by the radiative forcing regardless of what global temperature registers as it's being held back until the cold storage from the previous ice-age is gone.
So, I'd suggest to modelers & others, that heat-transfer is the main driver now and without assessing the volume heat transfer by analyzing air masses, their volume, temperature, humidity and direction there's no way to be predictive of these on-the-ground radical changes such as at Disco Bay.

I second your opinion. I looked at the meaning of the exotic word "heft" on google (the weight of someone or something), and having found the meaning, I still don't understand what that concocted Heartland's sentence means. But looks like I must give up and conclude this concoction is impossible to understand by logic. Because, like most contrarian's statements, its purpose is to confuse rather than clarify things.
Well, Heartland got away relatively lightly, with comparing climate scientists to unibomber, maybe they don't get awaqy lighly with distorting CAS position, I hold by breath on it...

MA Rodger at 17:06 PM on 15 June 2013The anthropogenic global warming rate: Is it steady for the last 100 years? Part 2.
Tom Curtis @168.
You most likely still do get a wobble from calculating NA SST - SA SST. The actual values would require delving into grided data but the NCDC provide SST for differing latitudes that I recently graphed. (Thus the N Atlantic & N Pacific SST are combined.) The wobble has a definite "limp" for 0-30ºN and an 'anti-limp' in the Arctic. If you assume the limp & anti-limp can be explained away without diminishing the AMO as a natural wobbler of global temperature, and noting there is no matching wobble for Southern SST, I think the maximum contribution from these SSTs into the average global figure is about the same for both wobbles (the Arctic being smaller than the Northern tropics) at 0.065ºC peak-to-peak. T&Zh13 suggests a far higher figure: 40% of recent warming = 0.265ºC peak-to-peak.

Ari Jokimäki at 15:59 PM on 15 June 2013An estimate of the consensus project paper search coverage
Daniel, the consensus project did not use 'climate change' as criteria for anything. Preliminary sample was built using search phrases 'global climate change' and 'global warming'. And of course, simple mention of climate change (or specific search phrases used) doesn't suggest that paper supports AGW, hence a large proportion of neutral papers was found in the project.

The Statements on the Chinese Translation of the“Climate Change Reconsidered—NIPCC Report”
2013-06-14
The Chinese translation of the “Climate Change Reconsidered—NIPCC report” was organized by the Information Center for Global Change Studies, published in May 2013 through Science Press, with an accompanying workshop on climate change issues in Beijing on June 15, 2013. However, the Heartland Institute published the news titled “Chinese Academy of Sciences publishes Heartland Institute research skeptical of Global Warming” in a strongly misleading way on its website, implying that the Chinese Academy of Sciences (CAS) supports their views, in contrary to what is clearly stated in the Translators’ Note in the Chinese translation.
The claim of the Heartland Institute about CAS’ endorsement of its report is completely false. To clarify the fact, we formally issue the following statements:
(1) The translation and publication of the Chinese version of the NIPCC report, and the related workshop, are purely non-official academic activities the group of translators. They do not represent, nor they have ever claimed to represent, CAS or any of CAS institutes. They translated the report and organized the workshop just for the purpose of academic discussion of different views.
(2) The above fact was made very clear in the Translators’ Note in the book, and was known to the NIPCC report authors and the Heartland Institute before the translation started. The false claim by the Heartland Institute was made public without any knowledge of the translator group.
(3) Since there is absolutely no ground for the so called CAS endorsement of the report, and the actions by the Heartland Institute went way beyond acceptable academic integrity, we have requested by email to the president of the Heartland Institute that the false news on its website to be removed. We also requested that the Institute issue a public apology to CAS for the misleading statement on the CAS endorsement.
(4) If the Heartland Institute does not withdraw its false news or refuse to apologize, all the consequences and liabilities should be borne by the Heartland Institute. We reserve the right for further actions to protect the rights of CAS and the translators group.

Rob Honeycutt at 11:59 AM on 15 June 2013CO2 effect is saturated
To add to what Tom said, the flip side of the absurdity put forth by that WUWT post is that is fails to acknowledget that atmospheric CO2 in very high concentrations is clearly responsible getting the earth out of past deep glaciation events. That well documented relationship could never occur if the CO2 effect was fully saturated at lower concentrations.

Tom Curtis at 11:07 AM on 15 June 2013The anthropogenic global warming rate: Is it steady for the last 100 years? Part 2.
It has occurred to me that the most neutral definition of the AMO would be the unforced variation in North Atlantic SST. Given that forcing from aerosols is regionally confined, the forcing in the North Atlantic can be expected to differ substantially from global forcing, given that aerosol emissions from North America and Europe have varied substantially with changes in dominant fuel use, wars and emissions controls. Therefore, the least question beging approach to identifying the AMO in the twentieth century would be to determine the effect of NA forcing on NA SST by regression, then remove that influence mathematically. As water from the South Atlantic is fed into the Gulf Stream and hence influences NA SST, it may also be desirable to eliminate that influence by the same means. Having removed the influence of NA Forcings and SA SST from the NA SST, whatever remains would approximate to the unforced variation in SST. It may or may not contain a 70 year cycle of any significant magnitude.
I have two questions.
First, has anybody actually taken this approach and reported the results?
Second (specifically for KK Tung), if you identify the unforced SST variation in the NA by this means, and use that instead of your AMO in your multiple regression, what is the resulting anthropogenic trend?

K.a.r.S.t.e.N at 09:35 AM on 15 June 2013Has the rate of surface warming changed? 16 years revisited
Apologies for the very late comment. I'd quickly like to add the results published in [Stenchikov et al. 2009] to the debate. In their [Fig.2], OHC and surface temperature changes from GFDL-CM2.1 are juxtaposed. I think it is fairly representative for other GCMs. Given that the temperature signal fades out quickly, I wouldn't be too concerned regarding the impact upon the FR11 methodology. It remains small at all time scales. What remains indeed unaccounted for is the volcanic OHC imprint (which seems responsible for the trend difference between GCMs and FR11 highlighted in [Troy Masters] analysis). However, the restoration of the volcanic OHC imbalance introduces a fairly constant (underlying) trend which is implicitly accounted for by the FR11 method.
As to changes in forcing: We all agree that they won't be detected with the FR11 method (as pointed out in the paper). If one were to assume that non-volcanic OHC anomalies approximately correlate with ENSO (as the results of Balmaseda et al. seem to confirm), one is left with changes in external forcing which the FR11 method would certainly miss, namely anthropogenic aerosols and recent changes in volcanic aerosols. While I agree that the assumption of a constant anthropogenic aerosol forcing over the last 30-40 years is questionable, at least the forcing at the beginning (end of the 1970s) and the end (today) of the analysis is fairly similar to the best of my knowledge. While major volcanic eruptions are accounted for, the more recent smaller eruptions are omitted. I adopted Fig.5 in [Vernier et al. 2011] in order to update the FR11 method until Dec 2012 for GISS temperatures. As a result, the [previous] trend estimate increases [slightly] and the tail end goes up a bit. Apart from 2012, nothing to worry so far. Having seen several unusual cold spells in 2012, the dip is explicable with natural variability. I would be surprised to see another such unexpected dip in 2013.
Bottomline: Currently, I don't see strong evidence for undetected changes in forcing which isn't considered with FR11 (after having accounted for recent volcanic eruptions). The video (which I liked a lot) seems to be as valid as before.

I'd say you were on to something, save that the author of the article is Heartland's "Director of Communications," which indicates he's drawing a salary and is not merely being paid piecemeal. Of course, his brief biography at the bottom of the article shows he's also a former Washington Times reporter, and the rest of it suggests he's part of the conservative go-to group on such issues, so the error he's made is not really excusable for the reasons you suggest.

Tom Curtis at 08:43 AM on 15 June 2013Heartland's Chinese Academy of Sciences Fantasy
Danieltreed @5, I have examined that claim by Tol. To begin with, it is irrelevant that the search terms used in Cook et al return a smaller sample unless that sample is also skewed. Tol does indeed also claim that it is skewed, but it is possible to use the data he provides to determine the potential effect of that skew. As it turns out, because of the near identity of the number of papers in disciplines which are under represented, and those which are over represented, that potential effect is very small. In fact, as a percentage of endorsements and rejections, the maximum range in the result possible if the skew was corrected is between 97.4 and 98.6%, compared to the 98.04% from the abstract survey. I discuss this issue in more detail here (see the third example of "Tol's consistent bias").
I am not sure what you mean by saying "the endorsement graph is refuse". Indeed, such vague negative criticisms indicate only that you reject the study because it is ideologically inconvenient. People with genuine criticisms are able to state them coherently, and in such a way that people can examine them for flaws.
My best guess as to what you mean is that you are referring to Tol's claim that the pattern of increasing endorsements is purely a result of change of composition over time. If so, you should recognize that Tol's analysis fails because the trend towards increased endorsement is strongest in the period 1991-2000, during which time there is no trend in composition. In constrast, from 2001-2011 the trend in composition is strongest, while the trend in endorsement is much weaker. This pattern is part of the reason for the very low correlation between composition and endorsements (r2=0.065). Tol's claim that the trend in endorsements is based on a trend in composition, then, is based on a simple eyeball assessment of a graph and fails the simplest statistical test. I explain this in more detail here.
As it happens, what is actually happening is a trend towards increased endorsement with no change in compostion in the first period, while the trend in endorsement in the second period is largely explained by the trend in composition. This pattern fits the hypothesis that "...the fundamental science of AGW is no longer controversial among the publishing science community and the remaining debate in the field has moved to other topics." In particular, it fits the idea of increasing confirmation of AGW up to the IPCC TAR after which scientists increasingly accepted AGW as a working hypothesis except for a few hold outs who found that ideologically unacceptable.
Finally, no knowledgable person argues that AGW is true because a consensus of scientists accepts it. Nevertheless, scientists - especially climate scientists- are the experts in this field. "An expert is somebody who knows all the basic mistakes in a field, and how to avoid them." Therefore if you think those climate scientists have missed something basic, ie, something that can be identified in a blog without any background knowledge in climate science, you are almost certainly a crank on a par with people who claim to have invented perpetual motion, or proved that the world is flat. The climate scientists may be missing something which makes them wrong about AGW, but it will be something very subtle, or something very complex. And it won't turn up on WUWT.

Sudden_Disillusion @15 : I did read about the Savory talk in several places, but I also heard it harshly criticized. For example: James McWilliams in Slate and Chis Clarke at KCET.
I haven't looked at this issue in any detail myself, but a quick glance at those critiques leaves me skeptical of Savory's claims.
Unusually, Savory's talk was commented on favorably both at Climate Denial Crock of the Week and at Watt's Up With That. At WUWT, contrarian Tim Ball wrote a rebuttal.
My co-author, rustneversleeps, made a comment at Planet3.0 on the carbon sequestration potential of Savory's methods.

I suggest Dr. Richard Tol (or yourself) make a similar survey using your sampling method and category criteria and see how (or if) the results differ. Then you can even come back to discuss the ups and downs of each approach. I suspect after doing real research you would be less prone to dismissing others.
Nobody said consensus = science. This survey just shows that the 'skeptic' argument that "there is no consensus" is bogus. Of course, once you show that, goalposts move.

ClimateChangeExtremist @ 2
In addition to the benefits you list, LFTRs cannot be used to make bombs without killing the bomb makers and without screaming "Here I am!" once made. Furthermore, they lend themselves to small modular construction, ie. they could be made in factories and transported to their desired location via road transport. They do not need copius amouns of water, so can be put almost anywhere (NIMBYs permitting) and seeing as they run very hot, can be far more efficient. On top of all that they can be made to burn the existing nuclear waste that so excites the Greens. When running soley on thorium they burn nearly 100% of the fuel, not the 1 or 2% that uranium fueled reactors do.
With world oil supply being what it is, the 'danger' we face is that there is a breakthrough in the electrification of transport and coal is chosen to meet the rising need for electricity, with all that would mean for climate change.
I would far rather leave my family with some radioactive waste to contend with - they might use it to heat their houses - than I would leave them to starve because we just did not plan our energy production intelligently.
Anyone who thinks that climate science suffers at the hands of the fossil fuel industry has seen nothing like what they do to the nuclear industry.

The sampling used for that 97% consensus number is based on a ludicrous sampling technique.
They used the terms "global climate change" and "global warming"... anyone involved in SEO or PPC will tell you that is way too restrictive, and Dr. Richard Tol investigated the data, and found that the number of papers cited would have QUADRUPLED had the search terms included simply "climate change."
Tol lists other details about the flaw in the sampling. The "Endorsement" graph is statistical refuse. I find the entire argument that consensus=science to be absurd, but that for another day I suppose. -

Don, the writers at Heartland would probably defend themselves by claiming that they are simply selling their labor to the highest bidder, in the classic capitalist formulation. There is no ethical connection between them as ethical agents and the way that their labor is used by those who have bought that labor. If their funders want to shape public opinion in such and such a way, who are they to interject their own ethical concerns into the production process? If there were an ethical connection, they would be forced to admit that workers everywhere have a right to control the means of production, and do so in a way that is ethically suitable. That would be antithetical to their convictions about capitalism (which they developed independently, of course, of course).
No, no . . . they are just providing for their families, just doing their 9-5 . . . go on up the chain of command if you want to find a villain (and then back down to the shareholders and the great conundrum of democracy: how do you split responsibility 500 ways?

That the Heartland Institute seems endlessly capable of emitting this kind of effluvia is one of the more strange aberations of the age. Is it not a form of collective insanity?
There is evidence that the delusion is wearing thin. Oddly enough, the first part of the quote from the Heartland article, authored by Jim Lakely, contains what strikes me as an egregious Freudian slip. I was so struck by it that I went to the original article to see if it might be a mistake in dana's post. It is not. Here once again is the quote from Lakely's article:
"The Chinese Academy of Sciences (CAS) will present the two books at a June 15 event in Beijing, a landmark event that puts enormous scientific heft behind the questionable notion that man is responsible for catastrophically warming the planet."
Breaking this sentence down, I'd paraphrase the guts of it like this:
The CAS event will give enormous scientific credit to the idea that humans are causing global warming.
There is simply no rational way read Lakely's original sentence and come to the opposite conclusion. Lakely and his colleagues at Heartland may view our role in global warming as a "questionable notion," but that doesn't change the actual sense of what Lakely has written. One could, I suppose, somewhat inaccurately paraphrase the sentence this way:
The presentation of these two books at the CAS event will give enormous scientific credit to the idea that humans are causing global warming.
But that reading is even more embarrassing for the folks at Heartland.

Don9000 at 02:54 AM on 15 June 2013UK Secretary of State for the Environment reveals his depth of knowledge of climate change (not!)
William,
I think your estimate of a mid-22nd century appointment with 500 ppm atmospheric CO2 is a bit off. The atmosphere gained approximately 3 ppm CO2 in this past year and the average increase from 2000 to 2010 is about 2 ppm as seen in the graph found here:
www.esrl.noaa.gov/gmd/ccgg/trends/
If even the 2 ppm per year rate is used, if this rate of increase were to continue for the rest of the century, by 2100 the atmosphere will have gained approximately 174 ppm. That would bump the total up to 574 ppm. If the rate of increase is closer to 3 ppm, we could conceivably blow past 650 ppm by 2100.
This apparently inexorable upward trend is one reason I worry about the seemingly good news regarding the 3.8% decrease in carbon emissions that has just been seen in the US, even as globally emissions went up by 1.4% according to the IEA:That is to say, it seems to me that there is a good chance that scientifically challenged politicans and skeptics here in the US will, as they do whenever there is an unseasonable snowstorm or cold snap, seize on such news and think 'we've done our part' or conclude that the problem has gone away when the reality is that vastly greater reductions are required.

barry1487 at 02:19 AM on 15 June 2013Antarctica is gaining ice
Not sure if this has been mentioned, but 2012 study points to changing wind patterns responsible for increasing sea ice in the Antarctic:The ultimate cause of the wind and ice changes lies in the large-scale climate variability of the Southern Hemisphere. Antarctic sea ice can contain 35-year cyclic anomalies that might be partly aliased into our calculations, but our trends cover several such cycles and are consistent with longer-term studies. Aspects of the wind trends (and therefore ice-motion trends) can be attributed to large-scale modes such as the Southern Annular Mode and El Nino/Southern Oscillation. Modern trends in these modes could arise through natural variability, but some evidence suggests that they are forced by the Southern Hemisphere ozone hole and increased greenhouse gases. Our conclusions that ice-motion trends are dominated by winds, and that winds contribute significantly to ice concentration trends through both dynamic and thermodynamic effects, reinforce the need for a better understanding of both the wind changes and the anthropogenic forcing of relevant climate modes.http://xa.yimg.com/kq/groups/18383638/1671623978/name/Antarctic+sea+ice.pdf -

Walk away failsafe; cannot produce weapons grade material; far more efficient that uranium based power plants; far less waste of much shorter half life; thorium based nuclear power is such an obvious answer to our need for energy with buring fossil fuels.

Any claim is easily said. Providing evidence to support the claim is more difficult. Civil engineer, how about exercising some civility and engineering a discussion around where the SkS links failed? That way you can provide a valuable service to the entire community and become believable.

DSL at 00:03 AM on 15 June 2013An estimate of the consensus project paper search coverage
Daniel, the direction of research can be an indication of the paper's understanding of mainstream climate science. A team of herpetologists decides to study the long-term migration of a frog species. The team finds that the frog species is moving northward by about three kilometers per decade. The team writes the migration up and, in the discussion section, speculates about the future of the movement. The team assumes current mainstream estimates of future warming for the region, noting that the species may end up being caught between a rock and a hard place, since there is a natural barrier a few km to the north. That speculation is represented in the abstract. This paper explicitly endorses the mainstream theory (AGW), since the mainstream theory is the only one taken into account. The mainstream theory (is this what you refer to as a "myth"?) is anthropogenic global warming, and implicit in that theory is the continuation of warming as long as the greenhouse effect continues to be enhahnced.
True, it would be very difficult for such a paper to go against the mainstream view. After all, to do so would be to explicitly reject the mainstream theory of climate, and a reason would need to be provided. As science naturally becomes more interdisciplinary, trust is a major issue. The herpetologists must trust climate modeling to give them a realistic basis for useful speculation. In that way, the use of the mainstream view is a vote of confidence for the mainstream view. It's not simply "well, we were forced to use it." The herpetologists didn't have to use it. They could have simply relied on an extrapolation of their own data. Such an act would be less useful, even if it were tied to a physical mechanism (e.g. according to local data, it's getting warmer in this region).The herpetologists would be especially driven toward speculation if they had long-term data, and the recent data suggested highly unusual activity. There's absolutely nothing wrong with such speculation. It reflects the concern the scientists have for their research areas. I can't count the number of times people have essentially tried to argue (toward me) that nature is conservative and any unusual behavior or "wild" speculation must be the result of scientists trying to make an extra buck or keep their jobs. No. If the basic inputs change (e.g. rising system energy storage), every element of the system changes.
By the way, what were you referring to as a myth?

Sudden_Disillusion at 21:27 PM on 14 June 2013A Miss by Myles: Why Professor Allen is wrong to think carbon capture and storage will solve the climate crisis
All geoengineering solutions that I know of are inherently unsustainable. Except this one: http://www.youtube.com/watch?v=vpTHi7O66pI (inspiring TED talk by Allan Savory)
If this works it not only reverses desertification, provides stable food supplies for local people, and enhances biodiversity, but also addresses global warming by greatly increasing the worlds biomass ergo capturing and storing CO2.
I do not understand why this is nowhere to be found in the media. Here comes your daily conspiracy theory ;-)

Daniel, I suggest you read the paper, the criterion for determining whether a paper supports AGW are stated as clearly as one could reasonably expect. A paper on statistical downscaling (an area of climatology in which I have worked) is not a paper that seeks to determine whether climate change is anthropogenic or not, but it would not be unusual for such a paper to motivate the need for the study by mentioning in the abstract that the majority of climate change has ocurred due to fossil fuel use. In your view, would such a paper endorse AGW, and at what level according to the stated criterion for the TCP?

Dikran,
You seem to be echoing my concern in your last sentence. If a paper mentions climate change, but makes no mention of the cause, how can it be considered to support AGW? Even if the myth were true, many of the papers would still not likely take a stance, as most of these papers were not written by climatologists. The term "climate change" was not the issue in my post, but its selection as criteria for the paper.

Responding to civil engineer from here.
"I don't find the sks links that convincing" is not a useful comment. If you dont explain the problems you percieve with responses to Salby, then how are we to distinquish this from "I prefer a reassuring lie to an inconvenient truth"?.

Tom Curtis at 09:12 AM on 14 June 2013A short history of carbon emissions and sinks
Daniel @3, two points:
1) The NH seasonal CO2 flux is dominated by the growth and fall of leaves on deciduos trees. This is shown in measurements of CO2 concentration from Barrow (Alaska):
Looking closely, you can see that January corresponds to the nearly flat plateau at the peak of CO2 conenctration, and hence with a flux minimum. That is unsurprising in that the leaves have fallen, but are to cold to decompose. In contrast, July corresponds to the steep downward slope in CO2 concentration. Again this is unsurprising in that summer is a period of maximum plant growth.
The net effect of this, and of providing data for just two months is that the Jaxa data gives a very poor indication of annual CO2 flux from northern dedediduous forests, or indeed, northern tundra where similar considerations arise. It represents a snap shot of one month of maximum flux and one month of near zero flux in a cycle that is close to carbon neutral.
Similar considerations apply to the tropical forest, but are nowhere near as strong in that the difference between summer and winter growth are much smaller in the tropics.
2) Much of the original extent of the northern deciduous forest was deforested in the early twentieth century, or before. Since then, many areas previously denuded of trees have been allowed to regrow forest, and some forests still used for lumber are more heavilly managed allowing a greater retention of carbon. In contrast, large scale deforestation in the tropics has been a novel feature of the last few decades. Further, it is very poorly managed, with extensive logging in areas supposedly set aside as nature reserves. Consequently part of the difference between NH deciduous forest and tropical forest fluxes is simply a result of changes in land use rather than natural fluxes.
Given these two factors, the Gosat data is almost useless in isolation for determining the net natural flux for tropical forest and northern deciduous forest. It may well be useful when coupled with additional detailed knowledge, but I am not an expert and cannot comment on that.
