Amazongate: At last we reach the source
By Christopher Booker | The Telegraph | July 10, 2010
Last week, after six months of evasions, obfuscation, denials and retractions, a story which has preoccupied this column on and off since January came to a startling conclusion. It turns out that one of the most widely publicised statements in the 2007 report of the UN’s Intergovernmental Panel on Climate Change – a claim on which tens of billions of dollars could hang – was not based on peer-reviewed science, as repeatedly claimed, but originated solely from anonymous propaganda published on the website of a small Brazilian environmental advocacy group.
The ramifications of this discovery stretch in many directions. First, it seems to show that the IPCC – whose reports governments rely on to justify presenting mankind with the largest bill in history – has been in serious breach of its own rules.
Second, it raises hefty question marks over the credibility of the world’s richest and most powerful environmental pressure group, the WWF, credited by the IPCC as the source of its unsupported claim.
And third, it focuses attention once more on a bizarre scheme, backed by the UN and promoted by the World Bank, whereby the WWF has been hoping to share in profits estimated at $60 billion, paid for by firms all over the developed world.
“Amazongate”, it may be recalled, was one of the rash of scandals which rocked the authority of the IPCC last winter, when it was revealed that many of the more alarmist statements in its 2007 report originated not from peer-reviewed science but from papers written by environmental pressure groups. One which aroused particular controversy was a warning that climate change was putting at risk up to 40 per cent of the Amazon rainforest. Chapter 13 of the IPCC’s Working Group II report on “climate impacts” specifically claimed that “up to 40 per cent of the Amazonian forests could react drastically to even a slight reduction in precipitation”. It went on to say that this would cause such chaos in local climate systems that the forest could rapidly revert to savannah.
The only source cited for this claim was the Global Review of Forest Fires, a paper written for WWF and the International Union for Conservation of Nature in 2000, the lead author of which was an environmental activist and freelance journalist. This in turn appeared to cite a paper published in 1999 by a team led by Dr Daniel Nepstad, “senior scientist” with another advocacy group closely linked to the WWF, the Woods Hole Research Center. However, Nepstad’s paper was primarily concerned not with climate change but with the impact of logging and fires.
When this created a storm last January, the WWF quickly issued a “clarification”, stating that its own paper “does not say that 40 per cent of the Amazon forest is at risk from climate change”. But it went on to say that the real source of the claim quoted by the IPCC was a document, Fire in the Amazon, published by the “respected Instituto de Pesquiza Ambiental da Amazonia (IPAM)”. Headed by Nepstad, IPAM is a Brazilian advocacy group, also closely linked with the Woods Hole Research Center.
The document cited by the WWF, which it later described, after a full internal inquiry, as a “report”, proved remarkably difficult to track down. Since then, both the WWF and Dr Nepstad have cited other papers in support of their claim – but none of these provided any support for the specific claim about the impact of climate change made by the IPCC.
Only now, after I was able to confront them with evidence from an internet archive, has the WWF finally admitted the precise origin of the IPCC’s much-quoted claim. Fire in the Amazon, it turns out, was not a “report” or a scientific paper but, as the WWF now acknowledges, a “text published by IPAM… on its website in 1999”. It was merely a brief, anonymous and unreferenced note on the exposure of the forest to fire risks, posted in February 1999 and taken down four years later. Here, at last, is the sole source for the statement later published by the IPCC.
The original read: “Probably 30-40 per cent of the forests of the Brazilian Amazon are sensitive to small reductions in the amount of rainfall.” This was hyped up in the final drafting of the IPCC report, to claim that “up to 40 per cent of the Amazonian forests could react drastically to even a slight reduction in precipitation”. “Brazilian Amazon” – only around half the total rainforest area – was changed to include the entire forest. The word “sensitive” was changed to “react drastically”. And the original IPAM note had made no mention at all of climate change.
To begin with, this would seem to justify a formal complaint to the IPCC that it was acting in breach of its own rules. Annex 2 of its rules of procedure lays down that non-peer-reviewed material should only be cited when it has been subjected to rigorous critical appraisal and that “each chapter team should review the quality and validity of each source before including results from the source into an IPCC report”.
Last week I put it to the IPCC that it should at least acknowledge this blatant breach of its rules and withdraw the passage, as it did last winter when it was revealed that it had no scientific basis for claiming that Himalayan glaciers could disappear by 2035. To date I have had no reply.
Neither WWF nor Woods Hole come well out of this story. In seeking to justify their part in the IPCC’s statement, they have cited other studies which they claim support it – but neither, until now, has been honest enough to admit that it was based on an unsubstantiated website claim.
This curious episode may also point to another reason why WWF and Woods Hole have been so active in recent years to promote concern over the danger of global warming for the Amazon rainforest. As I revealed here on March 20, they have been closely allied in support of a scheme known as REDD (Reduction in Emissions from Deforestation and Degradation of Tropical Forests). Its aim is to turn the CO2 in forest trees into “carbon credits”, saleable on the world market to allow firms to continue emitting CO2. Backed by $80 million from the World Bank, WWF, Woods Hole and IPAM are partners in a consortium, supported by the Brazilian government, to protect and manage a vast area of forest in the Tumucumaque region, in return for which they would have the right to sell its carbon credits. In 2007 Dr Nepstad published a formula which would allow the carbon contained in the entire forest to be valued at $60 billion.
Although the REDD scheme was approved in principle at December’s UN Copenhagen conference, two serious snags remain. First, it has yet to be approved in detail (although they still hope to achieve this in Cancun later this year). Second, the US Senate still hasn’t passed its cap and trade bill, which would open up a lucrative new market for anyone involved in carbon trading, such as those with a stake in REDD.
Finally, we may recall, another newspaper recently published a prominent “correction” to its earlier report on Amazongate – accepting that “the IPCC’s Amazon statement is supported by peer-reviewed scientific evidence” and that this was “based on research by the respected IPAM which did relate to the impact of climate change”. Since neither of these statements seems to be true, perhaps we can look forward to a retraction of the retraction?
Equally unhappy may be all those global warming enthusiasts who took this climbdown as licence to crow shamelessly over those of us who, last January, helped to expose Amazongate as a major IPCC system failure. The IPCC, they chorused, had been totally vindicated, the climate change sceptics had been utterly routed. Today, I fear, it is they who have been put to rout and we who have been vindicated.
Climategate report: CRU enquiry
By Andrew Orlowski • The Register • 7th July 2010
The University of East Anglia’s enquiry into the conduct of its own staff at its Climatic Research Unit has highlighted criticisms of the department and staff conduct – but clears the path for the individuals concerned to carry on.
The CRU played an important role in writing the UN’s IPCC summaries on climate science, so the issue is far from a parochial one. The most serious charge is poor communication; Sir Muir Russell even calls for “a concerted and sustained campaign to win hearts and minds” to restore confidence in the team’s work.
Russell was appointed by the institution to investigate an archive of source code and emails that leaked onto the internet last November. The source code is not addressed at all. His report suggests that the problems were of the academics’ own making, stating that they were “united in defence against criticism”. Yet the enquiry found that despite emails promising to “redefine” the peer review publication process, and put pressure on journal editors, staff were not guilty of subverting the IPCC process, and their “rigour” and “honesty” were beyond question.
Leading academics were called for written and oral evidence before the Russell enquiry, and in many cases the report accepts their account of events. The subjects of their criticism were not invited, not were climate scientists critical of their behaviour. For example, in their capacity as IPCC gatekeepers, the academics are cleared of excluding critical evidence, and yet bending the rules to include supporting studies. To reach this particular conclusion, for example, the report finds a criterion: a “consistence of view” with earlier work. The earlier work here was in fact produced the academics under scrutiny. So, having compared the CRU academics’ work against their previous work, and found it to be consistent, they are cleared of malpractice.
Despite the gentlemanly and clubbable tone, the report nevertheless has deep systemic criticism of the institution and the team’s processes. UEA “fell badly short of its scientific and public obligations”, according to one review panel member, Lancet editor Richard Horton.
It criticises the team’s decision to curtail a temperature reconstruction at 1960, and splice on an instrumental temperature record, without explanation, noting:
“The figure supplied for the WMO Report was misleading in not describing that one of the series was truncated post 1960 for the figure, and in not being clear on the fact that proxy and instrumental data were spliced together. We do not find that it is misleading to curtail reconstructions at some point per se, or to splice data.”
There’s a selective approach to criticism of scientific techniques – officially, Muir Russell says it doesn’t examine the validity of scientific arguments. But as you can see, in places, it does. On the issue of the Yamal reconstruction, CRU is cleared but the related issues of basing the reconstruction on a limited sample of proxies, and using techniques which exaggerate and validate outliers (basically, one tree) is not addressed.
FOIA
On compliance with Freedom of Information requests, the inquiry found the CRU team evasive, and “found a tendency to answer the wrong question or to give a partial answer”. They also found “a clear incitement to delete e-mails, although we have seen no evidence of any attempt to delete information in respect of a request already made”. (Jones had told a US academic that “I think I’ll delete the file rather than send to anyone” and requesting deletions from other staff.)
The defensiveness “set the stage”, says Russell, for the barrage of FOIA requests last year, but “clear and early action would likely have prevented much subsequent grief”. It adds that “CRU helped create the conditions for this campaign by being unhelpful in its earlier responses”.
The institution itself had failed to anticipate the new FOIA regime, and let the academics run amok. Strangely it calls for “a concerted and sustained campaign to win hearts and minds” to restore confidence.
On information handling, the report “highlighted significant problems in the areas of: imbalance of authority; lack of effective challenge at appeal; over dependence on single individuals; inadequate escalation processes and limited strategic oversight.”
The panel avoided examining the scientific work of the CRU Team – as have the two other reviews of the leaked archive by Lord Oxburgh, and the Commons Select Committee on science. If the academics had used bats’ wings or tea leaves to create temperature reconstructions, that wasn’t a matter for any of the panels to judge. And this is undoubtedly a shortcoming. The voter is entitled to see the evidence and understand the arguments that may answer the question: “Is this climate thing anything to worry about?”
It’s worth taking a step back from the details of Climategate to understand the background to the enquiries. By understanding what the CRU academics do, we can judge how important the criticism of them may be – or not.
What did the CRU crew do?
The Climatic Research Unit is one part of the picture, an important one, but not at the heart of climate theory. They’re not physicists, and they don’t do the physics upon which competing explanations of how the climate works stand or fall, once measured against observation. So in that sense, ‘Climategate’ isn’t a ‘Climategate’ – it isn’t a Scopes Trial of the global warming theory.
But CRU does two important things that shape our understanding of the present and the past. CRU is one of a small number of bodies that calculates global temperature readings (of where we are today), and is probably the pre-eminent body that performs historical temperature reconstructions, quite literally writing or re-writing history. And its importance is magnified since the leading academics are also lead authors of the UN’s IPCC reports – the vast volumes policy makers like to cite as their scientific justification, but rarely read.
In the absence of a strong physics story, this temperature work became hotly contested. The biggest bone of contention is whether modern, post-1850 warming is anomalous. If it is, then the likelihood that we were in strange and uncharted territory is much greater. If it isn’t, then consequently, the need for “urgent political action” – involving sweeping changes to industrial policy and social policy – became weaker.
The father of modern climatology, HH Lamb, founded CRU in 1972, and the building the academics work in takes his name. When Lamb contributed to the first IPCC report in 1990 the historical temperature record looked like this.
Lamb’s temperature graph, featured in the first IPCC report in 1990
By 2001, it looked like this.
Without the error bars (grey), the Medieval Warm Period disappears Source: IPCC TAR 2001
What Climategate is largely about, then, is whether the academics were justified in making that Medieval Warm Period disappear.
Unfortunately, none of the three ‘independent’ reviews have grappled with this. The absence of anomalous warming doesn’t, as some skeptics say, make the problem go away. But it takes the issue back onto the blackboard, back into realms of the potential threats. It certainly removes much of the impetus for a sweeping and urgent political program of mitigation.
Yet in the academics’ own words, we learn that the recent burst of warming, while real, is far from unusual.
One of the leading CRU academics, Keith Briffa, wrote that:
“I know there is pressure to present a nice tidy story as regards ‘apparent unprecedented warming in a thousand years or more in the proxy data’ but in reality the situation is not quite so simple. We don’t have a lot of proxies that come right up to date and those that do (at least a significant number of tree proxies ) some unexpected changes in response that do not match the recent warming. I do not think it wise that this issue be ignored in the chapter…
“For the record, I do believe that the proxy data do show unusually warm conditions in recent decades. I am not sure that this unusual warming is so clear in the summer responsive data. I believe that the recent warmth was probably matched about 1000 years ago.”
In an interview in February, CRU director Phil Jones agrees that recent warming isn’t statistically significant, and is matched by previous periods in the instrumental record – such as 1860 to 1880.
The sensible end of the climate debate hinges on how much of a lasting consequence an increase in CO2 has on the climate system. Some prominent scientists who as recently as 2001 were lead authors for the IPCC don’t dispute there’s an effect, but maintain that once it’s worked itself out, the effect is small.
Proponents of large positive CO2 feedbacks have pointed to various ‘fingerprints’ which are absent, or refuse to manifest themselves. Greenhouse gas warming was supposed to create a telltale warming of the troposphere, but instrumental readings show no such evidence. More recently, they have posited that CO2 must have caused warming, but this is still trapped in the oceans. This “missing heat” has yet to be found, and in the Climategate archive we find US scientist Kevin Trenberth expressing frustration: “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t,” adding that “we can’t definitively explain why surface temperatures have gone down in the last few years. That’s a travesty!”
For Trenberth, if we had better instruments, we’d find the heat. For skeptics, the heat might not be there.
By the mid-2000s the issue had become so politicised the academics were acting like a “priesthood”, in the words of environmental writer Fred Pearce, no friend of the skeptics. As Jones wrote in an email: “Many of us in the paleo field get requests from skeptics (mainly a guy called Steve McIntyre in Canada) asking us for series. Mike and I are not sending anything, partly because we don’t have some of the series he wants, also partly as we’ve got the data through contacts like you, but mostly because he’ll distort and misuse them.”
In a sense the CRU team are carrying the can for the physicists’ failure to do the science. ®
‘Climategate’ was ‘a game-changer’ in science reporting, say climatologists
By Fred Pearce | The Guardian | July 4, 2010
Science has been changed forever by the so-called “climategate” saga, leading researchers have said ahead of publication of an inquiry into the affair – and mostly it has been changed for the better.
This Wednesday sees the publication of the Muir Russell report into the conduct of scientists from the University of East Anglia’s Climatic Research Unit (CRU), whose emails caused a furore in November after they were hacked into and published online.
Critics say the emails reveal evasion of freedom of information law, secret deals done during the writing of reports for the UN’s Intergovernmental Panel on Climate Change (IPCC), a cover-up of uncertainties in key research findings and the misuse of scientific peer review to silence critics.
But whatever Sir Muir Russell, the chairman of the Judicial Appointments Board for Scotland, concludes on these charges, senior climate scientists say their world has been dramatically changed by the affair.
“The release of the emails was a turning point, a game-changer,” said Mike Hulme, professor of climate change at the University of East Anglia. “The community has been brought up short by the row over their science. Already there is a new tone. Researchers are more upfront, open and explicit about their uncertainties, for instance.”
And there will be other changes, said Hulme. The emails made him reflect how “astonishing” it was that it had been left to individual researchers to police access to the archive of global temperature data collected over the past 160 years. “The primary data should have been properly curated as an archive open to all.” He believes that will now happen.
Bob Watson, a former chair of the IPCC and now chief environment scientist for the British government, agreed. “It is clear that the scientific community will have to respond by being more open and transparent in allowing access to raw data in order that their scientific findings can be checked.”
In addition, Bob Ward, policy director of the Grantham Research Institute on Climate Change at the London School of Economics, said: “Researchers have to accept that it won’t just be their science that is judged but also their motives, professionalism, integrity and all those other qualities that are considered important in public life.”
Researchers outside Britain say a row that began in Norwich now has important implications for the wider scientific community round the world.
“Trust has been damaged,” said Hans von Storch of the KGSS Research Centre in Geesthacht, Germany. “People now find it conceivable that scientists cheat and manipulate, and understand that scientists need societal supervision as any other societal institution.”
The climate scientist most associated with efforts to reconciling warring factions, Judith Curry of the Georgia Institute of Technology, said the idea of IPCC scientists as “self-appointed oracles, enhanced by the Nobel Prize, is now in tatters”. The outside world now sees that “the science of climate is more complex and uncertain than they have been led to believe”.
Some IPCC scientists are in denial on this issue, she said, arguing that they would like to see the CRU incident as “an irrelevant blip” and to blame their problems on “a monolithic denial machine”, but that won’t wash.
Roger Pielke Jr of the University of Colorado agreed that “the climate science community, or at least its most visible and activist wing, appeared to want to go back to waging an all-out war on its perceived political opponents”.
He added: “Such a strategy will simply exacerbate the pathological politicisation of the climate science community.” In reality, he said, “There is no going back to the pre-November 2009 era.”
Curry exempted from this criticism Phil Jones, CRU director and the man at the centre of the furore. Put through the fire, “Jones seems genuinely repentant, and has been completely open and honest about what has been done and why… speaking with humility about the uncertainty in the data sets,” she said.
The affair “has pointed out the seamy side of peer review and consensus building in the IPCC assessment reports,” she said. “A host of issues need to be addressed.”
The veteran Oxford science philosopher Jerome Ravetz says the role of the blogosphere in revealing the important issues buried in the emails means it will assume an increasing role in scientific discourse. “The radical implications of the blogosphere need to be better understood.” Curry too applauds the rise of the “citizen scientist” triggered by climategate, and urges scientists to embrace them.
But greater openness and engagement with their critics will not ensure that climate scientists have an easier time in future, warns Hulme. Back in the lab, a new generation of more sophisticated computer models is failing to reduce the uncertainties in predicting future climate, he says – rather, the reverse. “This is not what the public and politicians expect, so handling and explaining this will be difficult.”
New Chinese study disputes the hockey stick conclusions
July 4, 2010 by Anthony Watts
China’s 2,000 Year Temperature History
While Mann claims his hockey stick science to be “vindicated”, we have this from World Climate Report, a new peer reviewed study that illustrates that the current warm period we live in is neither unique nor unprecedented. They also manage to point out the key issue, the uncertainty of proxies such as used by Mann et al. – Anthony
We constantly hear that the warmest years on record have all occurred in the most recent decades, and of course, we are led to believe this must be a result of the ongoing buildup of greenhouse gases. In most places, we have approximately 100 years of reliable temperature records, and we wonder if the warmth of the most recent decades is unusual, part of some cyclical behavior of the climate system, or a warm-up on the heels of a cold period at the beginning of the record. A recent article in Geophysical Research Letters has an intriguing title suggesting a 2,000 year temperature record now exists for China – we definitely wanted to see these results of this one.
The article was authored by six scientists with the Chinese Academy of Sciences in Beijing, the State University of New York at Albany, and Germany’s Justus-Liebig University in Giessen; the research was funded by the Chinese Academy of Sciences, National Natural Science Foundation of China, and the United States Department of Energy. In their abstract, Ge et al. tell us “The analysis also indicates that the warming during the 10–14th centuries in some regions might be comparable in magnitude to the warming of the last few decades of the 20th century.” From the outset, we knew we would welcome the results from any long-term reconstruction of regional temperatures.
The authors begin noting that “The knowledge of past climate can improve our understanding of natural climate variability and also help address the question of whether modern climate change is unprecedented in a long-term context.” We agree! Ge et al. explain that:
“Over the recent past, regional proxy temperature series with lengths of 500–2000 years from China have been reconstructed using tree rings with 1–3 year temporal resolution, annually resolved stalagmites, decadally resolved ice-core information, historical documents with temporal resolution of 10–30 years, and lake sediments resolving decadal to century time scales.”
However, the authors caution “these published proxy-based reconstructions are subject to uncertainties mainly due to dating, proxy interpretation to climatic parameters, spatial representation, calibration of proxy data during the reconstruction procedure, and available sample numbers.”
Ge et al. used a series of multivariate statistical techniques to combine information from the various proxy methods, and the results included the reconstruction of regional temperatures and an estimate of uncertainty for any given year. They also analyzed temperature records from throughout China over the 1961 to 2007 period and established five major climate divisions in the country (Figure 1).
Figure 1. Types, lengths, and locations of proxy temperature series and observation used in the Ge et al. study. The five climate regions were based on a “factor analysis” of the 1961–2007 instrumental measurements. Grey shading indicates elevation (from Ge et al., 2010).
The bottom line for this one can be found in our Figure 2 that shows the centennially-smoothed temperature reconstruction for the five regions of China. With respect to the Northeast, Ge et al. comment “During the last 500 years, apparent climate fluctuations were experienced, including two cold phases from the 1470s to the 1710s and the 1790s to the 1860s, two warm phases from the 1720s to the 1780s, and after the 1870s. The temperature variations prior to the 1500s show two anomalous warm peaks, around 300 and between approximately 1100 and 1200, that exceed the warm level of the last decades of the 20th century.” The plot for the Northeast shows warming in the 20th century, but it appears largely to be somewhat of a recovery from an unusually cold period from 1800 to 1870. Furthermore, the plot shows that the recent warming is less than warming that has occurred in the past.
Figure 2. Five regionally coherent temperature reconstructions with 100-year resolution; the dashed line is the part with fewer series used; and the solid line is the mean value. The shaded areas are the two coldest periods, during the 1620s–1710s and 1800s–1860s (from Ge et al., 2010).
The Central East region also has a 2,000 year reconstruction and Ge et al. state “The 500-year regional coherent temperature series shows temperature amplitude between the coldest and warmest decade of 1.8°C. Three extended warm periods were prevalent in 1470s–1610s, 1700s–1780s, and after 1900s. It is evident that the late 20th century warming stands out during the past 500 years. Considering the past 2000 years, the winter half-year temperature series indicate that the three warm peaks (690s–710s, 1080s–1100s and 1230s–1250s), have comparable high temperatures to the last decades of the 20th century.” No kidding – the plot for the Central East region shows that the warmth of the late 20th century was exceeded several times in the past.
Commenting on the Tibet reconstruction, Ge et al. state “The warming period of twenty decadal time steps between the 600s and 800s is comparable to the late 20th century.” In the Northwest, they note “Comparable warm conditions in the late of 20th century are also found around the decade 1100s.” Unfortunately, no long-term reconstruction was possible for the Southeast region.
In summarizing their work, Ge et al. report :
From Figure 3 [our Figure 2 –eds.] , the warming level in the last decades of the 20th century is
unprecedented compared with the recent 500 years. However, comparing with the temperature variation over the past 2000 years, the warming during the last decades of the 20th century is only apparent in the TB region, where no other comparable warming peak occurred. For the regions of NE and CE, the warming peaks during 900s–1300s are higher than that of the late 20th century, though connected with relatively large uncertainties.
We get the message – the recent warming in at least several regions in China has likely been exceeded in the past millennium or two, the rate of recent warming was not unusual, and the observed warming of the 20th century comes after an exceptionally cold period in the 1800s.
Declaring that anthropogenic greenhouse gas emissions have pushed modern temperature beyond their historical counterparts disregards the lessons of 2,000 years of Chinese temperatures.

Waxman Malarkey 4: Impact Zone Ireland
July 1, 2010 by Willis Eschenbach
In part 4 of this series, I take a look at the Waxman Markey claims about the Emerald Isle, Impact Zone Ireland. My previous analyses of the same site were Waxman Malarkey: Impact Zone US Northeast, Australia, and Alaska.
Having run short of other scares, the W/M folks want to convince us that Ireland is facing a simultaneous drought and flood … it’s the alarmist’s dream, the universal disaster:
Figure 1. Our future according to Waxman-Markey
How does that work?
Here’s their claim:
THE MISTY ISLAND DRIES OUT
Irish citizens have access to 5 times as much fresh water as the average European. High measures of annual rainfall and low evaporation rates have left a legacy of short coastal streams on peat covered hills and a maze of bogs and lakes along flood-prone inland rivers. However, this legacy may be broken as climate change could yield too much water in some places at some times and too little of it in other places at the same time. Scientists predict that by 2050 winter rainfall will increase by 12 percent and summer rainfall will decline by the same percentage.
…
Most of the current primary crops in Ireland are already showing evidence of decline. The potato in particular is highly dependant on adequate water supply so it may cease being a commercially viable crop. It is difficult to comprehend that the potato, a part of the landscape so intertwined in Ireland’s culture and history, may not feature strongly in its future.
With hotter, drier summers reducing the summer water supply in inland areas, water accessibility, which currently isn’t necessary for the majority of Irish farming, may necessitate the development of new irrigation systems, which will compete with industrial and residential water demands.
Let me take these claims one at a time. First:
Irish citizens have access to 5 times as much fresh water as the average European.
The citation to this is a site called “Irish Climate”. I do not find any support for the “5 times as much fresh water” claim there … or anywhere. But then “Irish Climate” is a strange site, chock full of unverified claims and alarmist scenarios. In addition, their advertising scheme is to drop ads for things like “Online Slots” into the text at random. I was particularly taken with this one:
So yeah, too bad that things could maybe kinda change in Ireland…it’s not like in Africa, where they had it sooooo good until global warming and then BAM! Online Slots! Suddenly people were poor and starving and sick and illiterate and slaving under corrupt and brutal gangs posing as governments and religions. All since, like, 2006 or so, when the media and corporate and political world started using hip words like ‘green’ and ‘sustainable’ to prove that Things Were Being Done.
I never knew online slot machines could cause so much damage. (I disabled the link in that quotation from the site, to prevent further child deaths). But I digress …
I find no scientific support for the “5 times” claim. Actually, I was surprised when I looked into the famous Irish rain to find that the island only gets about about 1.1 metres (46″) of rain per year. So are they saying that Europeans are only getting a fifth of that (230 mm, or 9″) of rain per year? No way. So what do they mean? The world wonders.
In any case, my investigation of the Irish rain leads me to their second claim, that:
However, this legacy may be broken as climate change could yield too much water in some places at some times and too little of it in other places at the same time. Scientists predict that by 2050 winter rainfall will increase by 12 percent and summer rainfall will decline by the same percentage.
“Scientists predict”? I doubt it. Ireland is a postage stamp sized country, there’s no climate model in the world that claims accuracy at that small a scale. And climate models do very poorly at predicting rainfall in any case. So let’s look at some data. Figure 2 shows two different rainfall datasets, once again from the marvelous KNMI site.
Figure 2. Historical Irish rainfall for summer (March-August) and winter (September-February) for the area bounded by 50°-55°N, 5°-10°W.
As you can see, there is no trend in Irish rainfall, either in the summer or the winter. So once again their claims are nothing but alarmists crying wolf.
Next, let’s look at their claim that:
Most of the current primary crops in Ireland are already showing evidence of decline. The potato in particular is highly dependant on adequate water supply so it may cease being a commercially viable crop. It is difficult to comprehend that the potato, a part of the landscape so intertwined in Ireland’s culture and history, may not feature strongly in its future.
The site for investigating claims like this one is marvelous UN FAOSTAT site. It contains every agricultural statistic imaginable. It shows that 90% of Ireland’s crop production (by tonnage) is in five crops – barley, oats, wheat, potatoes, and sugar beets. Here is the production of those crops since 1961, the start of the FAO database:
Figure 3. Production of the five main Irish crops. The sugar beet data ends in 2005, with the other datasets going to 2008.
So is potato production dropping as they claim? Most definitely … but not because of any change in the rainfall. It has been dropping since the start of the record. Why? Because farmers plant what they can make the most money on for the least effort and risk. Farmers aren’t fools.
Note also that the total production of the five main crops has not changed in half a century. This shows that, rather than Irish production decreasing because of any change in climate, all that is happening is the farmers are shifting from one crop to another.
There is another way to see if the changes in food production are climate related. This is to look at the yields of the crops. “Yield” is the amount of the foodstuff which is produced per hectare. Figure 4 shows the change in yields over a half century:
Figure 4. Crop yields for the main Irish crops
If changes in the climate were affecting the crops, we would see a reduction in the yields. Instead of seeing that, we see that the yield of every one of the crops has been increasing over the period. So whatever has been convincing the Irish farmers to change their mix of crops, it hasn’t been the climate.
Finally, further down on the page, the Waxman Markey site makes the following claim:
The Irish landscape faces many pressures from global warming that will result in visual changes to vegetation and land use. Losses of habitat vital to many species of flora and fauna and the stability of the landscape itself will change due to greater weather extremes. Arable land in particular regions of the country will continue to grow fields of wheat, barley, and corn as climate changes. In other regions, however, with the emergence of warmer and dryer summers, brown fields of grass during the summer months will become much more common.
The curlew, a beloved Irish bird known for its distinct cry, is endangered by climate change.
But even a rabid AGW carbon control site like the Conservation Volunteers of Northern Ireland doesn’t believe that. They say (emphasis mine):
Threats to the Curlew
There has been a rapid decline in the population of breeding curlew in Northern Ireland over the last 25 years. The most recent survey in 1999 suggested that breeding pairs have declined by 58% since 1988. This rapid decline has been reflected in other parts of the UK and the Republic of Ireland.
The decline of the curlew is linked to the loss of their wetland habitat mainly through more intense agricultural practices, drainage of wetland areas and overgrazing by livestock. It is thought that curlews are now more vulnerable to predation and this is having a further impact on their population. As the birds nest on the ground, they are vulnerable to recent increases in predators such as foxes and crows. The poor survival rate of young birds is known to be a key factor in the decline of curlew.
In Northern Ireland, the curlew is a legitimate quarry species during the open season, although it is thought that the numbers shot are very small. It is fully protected elsewhere in the UK.
Summary: The claimed future changes in Irish rainfall have no scientific validity. The changes in potato production are unconnected to the climate. Agricultural production is not declining. The drop in numbers of the curlew is due to drainage of wetlands. And once again, the Waxman site contains nothing but malarkey.
Waxman Malarkey 3: Impact Zone Alaska
June 30, 2010 by Willis Eschenbach
Once again, I return to that endless font of misinformation, the Waxman Markey website. In this case, I look at their claims about Alaska. This one will be short and sweet. Their claim is that Alaska is roasting, as in the picture below:
Figure 1. The dessert known as “flaming baked Alaska”. Ice cream covered with meringue, doused with brandy, and set on fire. Sweet.
The Waxman Markey website page on Alaska says:
Over the past 50 years, Alaska has warmed by 4 to 7 degrees Fahrenheit, much more than anywhere in the lower 48 states. This dramatic temperature change is causing the landscape of Alaska to change faster than anywhere else in the United States, threatening infrastructure, wildlife, and Native Alaskan culture.
I fear that these numbers must be from the well-known Government Misinformation Agency.
Figure 2 shows the real numbers:
Figure 2. Alaskan temperatures, as the average of all first-order stations in the state.
There are a few things we can see here. First, Fig. 1 clearly shows the dependence of Alaska temperatures on the Pacific Decadal Oscillation (PDO). The PDO is a long-term shift in Pacific sea surface temperatures. The PDO has a warm phase and a cool phase, as shown in Figure 3. It shifts from one phase to the other every thirty years or so.
Figure 3. Cool (positive) and warm (negative) phases of the PDO. IMAGE SOURCE
The PDO shifted to the cool phase in the late 1940s. It went back to the warm phase in 1976-77. And recently, it has gone back to the cool phase. This is clearly visible in the Alaska temperatures. As much as Waxman Markey wants to blame the shift in Alaskan temperatures on “global warming”, the science says otherwise. The changes are due to the shifts in the PDO.
Second, their claim that Alaska has “warmed by 4 to 7 degrees Fahrenheit” is not true. The largest trend to 2009 in the Alaska temperatures is 1954-2009, which is 3.24 degrees.
I also note that they are using a very different period from the one they used in their claims about the US Northeast, where they used the trend from “the 1970′s”. Obviously, they are picking their time period to exaggerate their claims …
The main point here is that because the PDO gives Alaska warm periods and cool periods, it is meaningless to use any trend starting from a cool period and ending in a warm period, or vice versa. Yes, you can get a positive trend from anywhere on the left half of the graph to anywhere on the right side of the graph … but that doesn’t tell us anything about what’s happening.
Short and sweet.
Waxman-Malarkey: Impact Zone US Northeast
By Willis Eschenbach | June 29, 2010
In the US House of Representatives, there is something curiously yclept the “Select Committee on Energy Independence and Global Warming” despite the lack of connection between the energy independence and warming. They have a very professionally done website, filled with some of the most outrageous misrepresentations imaginable. It is designed to promote the “Waxman-Markey” cap and trade carbon tax bill by means of the historically tried and tested “Big Lie” method, viz:
All this was inspired by the principle–which is quite true within itself–that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods.
It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.
I’m going to take the website’s misrepresentations one at a time, as time permits. The first one is from a page entitled “Impact Zone – U.S. New England“, which contains this lovely photograph designed to tug at the heartstrings:
Figure 1. Photo of maple trees in New England, professionally chosen for maximum emotional impact.
The accompanying text says (emphasis mine):
Global Warming in New England: Slushier Slopes and Faded Foliage
Life and economic activity across New England is marked by the seasons – maple sugaring in the spring, trips to the beach in the summer, the riot of color of the fall foliage, and the swoosh of skis and skates in the winter. This familiar cycle is already changing in noticeable ways.
Changing seasons
Since the 1970′s average winter temperatures have risen more than 4 degrees Fahrenheit in the Northeast region. If the current rate of heat-trapping emissions continues, by 2070 summers in Boston will feel like those of South Carolina today. By the end of the century, temperatures could rise up to 14 degrees Fahrenheit in the region. Cities across New England, which historically experience only one or two days per year above 100 degrees each summer, could average 20 such days per summer, while more southern cities such as Hartford could average nearly 30 days.
The character of the seasons will change significantly. Spring could arrive three weeks earlier, with summer lengthening by about three weeks, autumn becoming warmer and drier, and winter becoming shorter and milder.
So what’s wrong with that?
Well, once we note the conjectures (marked by the weasel words in bold), we see that most of it is nothing but unfounded, un-cited alarmist claims about imaginary future calamities. They have presented only one claim of fact – that winter temperatures in the Northeast Region have risen by more than 4°F.
Now, the USHCN has the data for all of the states, as well as by region. The Northeast Region is the data that starts with “101″ in the first column. Figure 2 shows the temperature record for the four seasons, as well as the annual average temperature, for the Northeast Region:
Figure 2. Annual and seasonal temperatures, US Northeast Region. Photo shows winter surf in New England. PHOTO SOURCE.
As you can see, there has not been much of a change over the last 115 years in any of the seasons. The trend for all of the datasets is not significantly different from zero (winter p=0.06, spring p=0.15, summer p=0.34, fall p=0.68, annual p=0.06).
And more to the point, the winter trend over the last 40 years (1970-2009) is only 2.7°F, not the “more than 4 degrees Fahrenheit” claimed by their website. Such a swing is not surprising in a dataset such as the winter temperatures, which shows a 10 °F swing in one year, from 2001 to 2002.
But wait … there’s more. Because of the short length (40 years) and high variability of the 1970-2009 winter temperatures, the 1970-2009 trend is not significantly different from zero either (p = 0.12, a ways from significant).
SUMMARY: Their web page contains two misrepresentations of fact about US Northeast winters, two implied misrepresentations, and a big lie:
Misrepresentation of fact 1: the 1970-2009 winter temperatures have not “risen more than 4 degrees Fahrenheit”, they have risen 2.7 degrees Fahrenheit. There is no rise of more than 4 °F in the winter temperature record, no matter where you start.
Misrepresentation of fact 2: the 1970-2009 winter trend is not statistically significant, so we cannot reject the null hypothesis that there is no trend at all, much less a claimed 4 °F trend.
Implied misrepresentation 1: The US Northeast winters are not warming. Over the full period of record (1895-2009), there is no statistically significant trend in the winter record.
Implied misrepresentation 2: The seasonal temperatures in the US Northeast are not warming. Over the full period of record (1895-2009), there is no statistically significant trend in the overall record for any season.
THE BIG LIE: When you look at the full record for the US Northeast, there is no statistically significant trend anywhere. Neither spring, summer, winter, fall, nor the full annual average temperatures have any statistically significant trend for the period of the study, 1895-2009. And remember, this is measured by ground stations that contain spurious UHI warming, and there still is no warming trend.
The big lie is that the US Northeast is warming. The best records that we have say that it is not.
I will examine more of the malarkey from their web site as time permits, although the statements are so obviously untrue that it’s hardly sporting. It’s like shooting fish, not in a barrel, but in a bucket …

‘Biggest thing in farming for 10,000 years on horizon’
Dirtboffins argue for lawn-style perennial grainfields
By Lewis Page • The Register • 25th June 2010
Agro-boffins in America say that mankind could be on the verge of the “biggest agricultural breakthrough in 10,000 years”, as researchers close in on “perennial grains”.
At the moment, most grain grown around the world has to be replanted after every crop. Farming so-called “annual” grain of this sort consumes a lot of resources and is hard on the land, which is especially worrying as half the world’s population lives off farmland which could easily be rendered unproductive by intensive annual grain harvests.
“People talk about food security,” says soil science prof John Reganold. “That’s only half the issue. We need to talk about both food and ecosystem security.”
Reganold and his fellow dirtboffin Jerry Glover argue that perennial grain – in addition to not needing replanting, so saving on passes of farm machinery over the ground, fuel etc – would have a much deeper and more powerful root system than annuals, rather like a well-kept lawn. This would mean that it used water much more efficiently; and water is often a major issue in agriculture and its impact on its surroundings.
Other benefits of a deep perennial root system beneath farmers’ fields would be less erosion and better carbon sequestration. Perhaps most tellingly of all, such a field might need as little as 3 per cent of the fertilisers required by annuals. Not only are nitrate fertilisers energy-intensive to make, they are also prone to washing out of fields to pollute water supplies, kill habitats and cause other eco mischief. Perennial fields would also require much less in the way of herbicides to control weeds.
At the moment, perennial grains capable of matching annuals don’t exist. However, Reganold and Glover argue that they can be bred with sufficient effort: it’s purely a matter of resources put into research. It’s perhaps worth noting that there’s not as much obvious revenue in perennials for major agro firms as there is in some kinds of annuals – there would be no continual requirement for new seed.
The two researchers, and many colleagues in the business, argue that with enough development cash perennial grain could be available in less than 20 years – representing, in their view, as great a step forward in food production as the original shift by the human race out of hunter-gathering and into farming in the first place.
The assembled dirt experts have convinced the editors of hefty boffinry mag Science, where their arguments are presented (subsciption required for full text).

The Irony, It Burns …
By Willis Eschenbach | Watts Up With That? | June 3, 2010
Anthony commented yesterday on the question of atolls and sea level rise here, and I had previously written on the subject in my post “Floating Islands“. However, Anthony referenced a paper which was incorrectly linked by New Scientist. So I thought I’d provide some more information on the actual study, entitled “The dynamic response of reef islands to sea level rise: evidence from multi-decadal analysis of island change in the central pacific”, by Arthur Webb and Paul Kench.
One of the ironies of the new paper involves the atoll of Amatuku in the island nation of Tuvalu. Amatuku became the first poster child of “drowning atolls” due to an article in the July/August 2003 issue of Sierra Magazine, the magazine of the Sierra Club. The article was entitled “High Tide in Tuvalu”, with the sub-title “In the tropical Pacific, climate change threatens to create a real-life Atlantis.” Here’s a recent photo of “Atlantis”:
Figure 1. Photo taken in the South Pacific nation of Tuvalu (8°S, 179°E), showing Amatuku Atoll and the abandoned causeway. PHOTO SOURCE
In the Sierra Magazine article the author described the terrifying effects of “global warming” on Amatuku Atoll, site of the Tuvalu Maritime Training Institute:
To explain global warming in stark detail, all Tito Tapungao has to do is show a visitor around the grounds of his school. Dressed in his sailor’s pressed whites, the chief executive officer of the Tuvalu Maritime Training Institute points out a small brick cabin built by missionaries in 1903. Now, a century later, annual high tides rise halfway up the bedposts.
YIKES! Be very afraid. So what is the irony in the new study?
Well, I’ll get to that. But first, a bit of history. The Sierra Magazine article was what impelled me to write my 2004 paper (Word Doc) on Tuvalu. I read that article, and my urban legend detector started ringing like crazy. Consider: the missionaries’ cabin was likely built a metre or so above high tide. Add another half metre for the floor, and a half metre to get “halfway up the bedposts” … no way, I thought, that the sea level has risen two metres in Tuvalu.
Upon further investigation, I found out that the answer was already known, because geologists had studied (pdf) the area. They found the changes in the shape of Amatuku Atoll were a result of changing currents from major alterations made in the reef during World War Two. A channel was cut from the lagoon to Amatuku, and a causeway was constructed between Amatuku and nearby Malitefale Atoll. Fill to make the causeway came from “borrow pits”, holes dug in the reef flats to provide coral rubble for the construction. And some decades after the war, further borrow pits were dug to provide building materials for the Maritime Institute. The swimmers in the Fig. 1 are swimming in one of the old borrow pits. Here’s an aerial view of the changes:
Figure 2. Amatuku and Malitefale Atolls, Tuvalu, South Pacific. Amatuku is less than a kilometre long.
As you can see, the changes in the reef structure were quite extensive. All of these alterations in the reef changed the currents around the two atolls. And of course, as a result, the shape of the atolls changed. This change in shape is to be expected – after all, atolls are just piles of sand and rubble in the middle of a wild ocean. One of the results was the erosion (not from CO2, not from warming, not from sea level rise, but erosion from man-made changes in the reef) of the corner of the atoll where the missionaries’ cabin was located.
Over the years since I published my paper, I’ve taken a lot of heat for my claims. I’ve gotten plenty of irate emails from folks in Tuvalu and around the world, emails castigating me for suggesting that the rising sea levels won’t drown the atolls, emails impugning my ancestry, emails saying we’d soon see thousands of “climate refugees” from Tuvalu, emails proposing that I perform anatomically implausible acts of sexual auto-congress, and mostly emails saying that I was clearly wrong, that it was patently obvious that rising sea levels would inevitably drown the atolls, duh, so there.
OK, enough history. I got a pre-publication copy of the current paper under discussion from one of my secret underground (underwater?) sources, my thanks to WS. The abstract of the paper says (emphasis mine):
Abstract
Low-lying atoll islands are widely perceived to erode in response to measured and future sea level rise. Using historical aerial photography and satellite images this study presents the first quantitative analysis of physical changes in 27 atoll islands in the central Pacific over a 19 to 61 year period. This period of analysis corresponds with instrumental records that show a rate of sea level rise of 2.0 mm.y-1 in the Pacific.
Results show that 86% of islands remained stable (43%) or increased in area (43%) over the timeframe of analysis. Largest decadal rates of increase in island area range between 0.1 to 5.6 hectares. Only 14% of study islands exhibited a net reduction in island area. Despite small net changes in area, islands exhibited larger gross changes. This was expressed as changes in the planform configuration and position of islands on reef platforms. Modes of island change included: ocean shoreline displacement toward the lagoon; lagoon shoreline progradation; and, extension of the ends of elongate islands. Collectively these adjustments represent net lagoonward migration of islands in 65% of cases.
Results contradict existing paradigms of island response and have significant implications for the consideration of island stability under ongoing sea level rise in the central Pacific. First, islands are geomorphologically persistent features on atoll reef platforms and can increase in island area despite sea level change. Second; islands are dynamic landforms that undergo a range of physical adjustments in responses to changing boundary conditions, of which sea level is just one factor. Third, erosion of island shorelines must be reconsidered in the context of physical adjustments of the entire island shoreline as erosion may be balanced by progradation on other sectors of shorelines. Results indicate that the style and magnitude of geomorphic change will vary between islands. Therefore, Island nations must place a high priority on resolving the precise styles and rates of change that will occur over the next century and reconsider the implications for adaption.
Ahhh, vindication is sweet. The authors agreed totally with what I had written in 2004. Rising sea levels don’t destroy atolls, and their shape is always changing. Exactly what I had taken so much heat for saying.
In addition to the Abstract, the Conclusions of the paper are quite interesting. Here are some extracts (emphasis mine):
Conclusions
The future persistence of low-lying reef islands has been the subject of considerable international concern and scientific debate. Current rates of sea level rise are widely believed to have destabilised islands promoting widespread erosion and threatening the existence of atoll nations. This study presents analysis of the physical change in 27 atoll islands located in the central Pacific Ocean over the past 20 to 60 years, a period over which instrumental records indicate an increase in sea level of the order of 2.0 mm y-1.
The results show that island area has remained largely stable or increased over the timeframe of analysis. Forty-three percent of islands increased in area by more than 3% with the largest increases of 30% on Betio (Tarawa atoll) and 28.3% on Funamanu (Funafuti atoll [the main atoll in Tuvalu – w.]). There is no evidence of large scale reduction in island area despite the upward trend in sea level. Consequently, islands have predominantly been persistent or expanded in area on atoll rims for the past 20 to 60 years.
… Results of this study contradict widespread perceptions that all reef islands are eroding in response to recent sea level rise. Importantly, the results suggest that reef islands are geomorphically resilient landforms that thus far have predominantly remained static or grown in area over the last 20 – 60 years. Given this positive trend, reef islands may not disappear from atoll rims and other coral reefs in the near-future as speculated. However, islands will undergo continued geomorphic change. Based on the evidence presented in this study it can be expected that the pace of geomorphic change may increase with future accelerated sea level rise. Results do not suggest that erosion will not occur. Indeed, as found in 15% of the islands in this study, erosion may occur on some islands. Rather, island erosion should be considered as one of a spectrum of geomorphic changes that have been highlighted in this study and which also include: lagoon shoreline progradation; island migration on reef platforms; island expansion and island extension. The specific mode and magnitude of geomorphic change is likely to vary between islands. Therefore, island nations must better understand the pace and diversity of island morphological change and consider the implications of island persistence and morphodynamics for future adaptation.
Couldn’t say it better myself … and oh, yeah, what about the irony?
Well, Amatuku, the poster child of disappearing atolls, the threatened “real-life Atlantis”, home of the disappearing missionaries’ cabin, happened to be one of the atolls considered in the study. The authors found that despite the loss of the missionaries’ cabin, Amatuku increased in area by about 5% over the nineteen year period during which it was studied … ah, the irony, it burns.
Rebel scientists force Royal Society to accept climate change scepticism
By Ben Webster |Timesonline | May 29, 2010
Britain’s premier scientific institution is being forced to review its statements on climate change after a rebellion by members who question mankind’s contribution to rising temperatures.
The Royal Society has appointed a panel to rewrite the 350-year-old institution’s official position on global warming. It will publish a new “guide to the science of climate change” this summer. The society has been accused by 43 of its Fellows of refusing to accept dissenting views on climate change and exaggerating the degree of certainty that man-made emissions are the main cause.
The society appears to have conceded that it needs to correct previous statements. It said: “Any public perception that science is somehow fully settled is wholly incorrect — there is always room for new observations, theories, measurements.” This contradicts a comment by the society’s previous president, Lord May, who was once quoted as saying: “The debate on climate change is over.”
The admission that the society needs to conduct the review is a blow to attempts by the UN to reach a global deal on cutting emissions. The Royal Society is viewed as one of the leading authorities on the topic and it nominated the panel that investigated and endorsed the climate science of the University of East Anglia.
Sir Alan Rudge, a society Fellow and former member of the Government’s Scientific Advisory Committee, is one of the leaders of the rebellion who gathered signatures on a petition sent to Lord Rees, the society president.
He told The Times that the society had adopted an “unnecessarily alarmist position” on climate change.
Sir Alan, 72, an electrical engineer, is a member of the advisory council of the climate sceptic think-tank, the Global Warming Policy Foundation.
He said: “I think the Royal Society should be more neutral and welcome credible contributions from both sceptics and alarmists alike. There is a lot of science to be done before we can be certain about climate change and before we impose upon ourselves the huge economic burden of cutting emissions.”
He refused to name the other signatories but admitted that few of them had worked directly in climate science and many were retired.
“One of the reasons people like myself are willing to put our heads above the parapet is that our careers are not at risk from being labelled a denier or flat-Earther because we say the science is not settled. The bullying of people into silence has unfortunately been effective.”
Only a fraction of the society’s 1,300 Fellows were approached and a third of those declined to sign the petition.
The rebels are concerned by a document entitled Climate Change Controversies, published by the society in 2007. The document attempts to refute what it describes as the misleading arguments employed by sceptics.
The document, which the society has used to influence media coverage of climate change, concludes: “The science clearly points to the need for nations to take urgent steps to cut greenhouse gas emissions into the atmosphere, as much and as fast as possible, to reduce the more severe aspects of climate change.”
Lord Rees admitted that there were differing views among Fellows but said that the new guide would be “based on expert views backed up by sound scientific evidence”.
Bob Ward, policy director of the Grantham Research Institute on Climate Change at LSE, urged the other signatories to come forward. “If these scientists have doubts about the science on climate change, they should come out and speak about it.”
He said that the petition would fuel public doubt about climate change and that it was important to know how many of the signatories had professional knowledge of the topic.
Global Floating Ice In “Constant Retreat”???
By Willis Eschenbach | May 28, 2010
I don’t know what to make of this one. I was wandering the web when I came across a Reuters article about a scientific study called “Global Floating Ice In “Constant Retreat”: Study“.
The Reuters article opens with this arresting text (emphasis mine):
LONDON
Wed Apr 28, 2010 1:38pm EDT
(Reuters) – The world’s floating ice is in “constant retreat,” showing an instability which will increase global sea levels, according to a report published in Geophysical Research Letters on Wednesday.
Floating ice had disappeared at a steady rate over the past 10 years, according to the first measurement of its kind.
“Hello,” sez I, “how can the sea ice be in constant retreat?” I knew from my previous research that the global ice was not in any kind of retreat at all.
I was also suspicious because of the next part of the quote:
“It’s a large number,” said Professor Andrew Shepherd of the University of Leeds, lead author of the paper, estimating the net loss of floating sea ice and ice shelves in the last decade at 7,420 cubic kilometers.
I went off to find the actual paper, and discovered a curious thing.
So what did I discover … and why is their quote suspicious?
Let me start with why their quote is suspicious. It is their claim that the earth has lost 7,420 cubic kilometres of ice. As I have mentioned elsewhere, when I see numbers I automatically do an “order of magnitude” calculation in my head to see if they are reasonable or not.
I knew from my previous research that there is about twenty million square kilometres (km^2) of floating ice on the planet. I also knew that much of it out towards the edges is only a metre or two thick.
So if the ice averaged say 1.5 metres thick out at the edges where the loss happens, a seven thousand cubic kilometer loss would mean a total loss of ice area of about five million km^2, or a quarter of the area of the world’s floating ice. I think someone would have noticed that before now …
Of course, that made me wonder if the problem was in the study, or in the Reuters quote. However, that same number (7,420 cubic kilometres lost) appeared in no less than 81 other online publications. So I went haring off to find the article.
One of publications reporting the story, NewScientist, 5 May, 2010, gave the “doi:” for the article. The DOI is the “Digital Object Identifier”, and it should link directly to the article, which was supposed to have been published by Geophysical Research Letters (GRL) on Wednesday, April 28th … but the curious thing I discovered was that the DOI didn’t work.
Someone had commented on that, saying “The DOI doesn’t work.” This was replied to by someone called Marshall, from newscientist.com, who said:
Hi Eric, it’s because the article hasn’t been published on GRL’s website yet. The DOI is taken directly from our press copy of the paper, so once the article is published it should work.
OK, fair enough … although the original Reuters article was allegedly published on April 28, and today is May 28, and the DOI still isn’t working. So I went to the GRL web site to see what I could find.
I first did a search for any articles by “Shepherd” in “GRL” for “2010″, and I got this:
Figure 2. Ooooops …
Thinking it might have been misfiled, I searched through all of the May articles for anything by Shepherd. Nil. I looked through the May articles for anything regarding “ice”. Nada. I repeated both searches for April. Once again, zip. Niente. Nothing.
I thought “Well, maybe it appeared in another journal”. So I took a look on Google, but I found nothing. Google did find 32,500 instances of “ice in constant retreat”, of which 7,550 also contained “GRL”.
Google also revealed that the report of the study has been picked up by ABC News, NewsDaily, Yahoo News, New Scientist, Arab News, and ScienceDaily. It was featured on Joe Romm’s global warming blog “ClimateProgress”. It has been referred to in blogs and news reports from India, Australia, Russia, and China. It shows up on TweetMeme, Huffington Post, and Facebook. Even Scientific American has an article on it.
So at this point, it has gone round and round the world. It has been illustrated with all kinds of pictures of melting ice, and of global ice extent, and (inevitably) of polar bears. It has been discussed and debated and dissected around the web.
And with all of that publicity, with all those news reports, with all that discussion and debate … as near as I can determine, despite Reuters saying it was published a month ago, the study has never been published anywhere.
Not only that, but nobody seems to have noticed that the study has never been published.
Well, that’s not entirely true. Scientific American must have noticed, because they quietly removed the page where they had published the report … but it is still in Google’s cache.
One last thing. In all of that, in the frenzy to get out tomorrow’s news today, in the rush to report the latest scientific rumour, people seem to have forgotten to ask … how is the global sea ice actually doing?
Glad you asked. Here’s today’s information, from Cryosphere Today:
Figure 3. Daily global sea ice anomaly (red line) compared to 1979-2008 average. Link contains full sized image.
As you can see, as of today, the global sea ice is exactly on the line representing the 1979-2008 average. So over the last ten years, instead of a loss of 7,420 cubic kilometres, the loss has been … somewhere around zero. Go figure.
