Yesterday, Dr Vincent Gray sent out his Climate Truth Newsletter (no. 310). In it he adverts to an outrageous admission of common sense by James Hansen. Years ago, Hansen admitted on his GISS web page that there’s no agreement among scientists on what constitutes an acceptable surface air temperature.
Sensationally, he also said that it’s IMPOSSIBLE to obtain a scientifically meaningful surface air temperature (SAT).
Now, with Hansen’s resignation from NASA, Gavin Schmidt has rushed in to take charge of these surprising admissions. Curiously, I see that Schmidt’s description is “NASA Official,” where Hansen was the “Responsible NASA Official.” Significant, interesting or irrelevant? Speculation might be endless…
The link above to the previous version of the page at the Wayback Machine is from 15 October, 2008, but that page is marked as last updated on 12 July, 2005. There are three more words in the body text of the current version than on the old page; I conclude they’re essentially identical.
These comments asserting the impossibility of determining the SAT put a disturbing slant on Hansen’s alarmism based on the SAT during the last 20 years of the 20th Century. Read more… »
The global temperature datasets are slow.
We usually have updates within 30 days of the end of a month, but most are about three months behind, with UAH four months slower than normal.
UAH MSU 7-2012
RSS MSU 8-2012
Anyone know why?
A new study shows modern temperatures are not unprecedented and disproves an important part of Mann’s “hockey stick” paper of 1999.
Orbital forcing of tree-ring data, J. Esper et al., says:
“… large-scale near-surface air-temperature reconstructions [specifically the hockey stick] relying on tree-ring data may underestimate pre-instrumental temperatures including warmth during Medieval and Roman times.”
This is beautiful.
It’s getting worse than they thought (for them!)
This insight into the NZ temperature record is from the resourceful Bob D. I’ve promoted it because it’s priceless. Bob says:
NIWA’s Climate Updates
I thought I’d share the local New Zealand temperatures over the last decade. I downloaded all NIWA’s Climate Updates from their website (the first one I could find was Oct 2001) and plotted the temperature anomalies that were published for each month.
Of course, what with Catastrophic Anthropogenic Global Warming and all, I expected to see temperatures rising (accelerating, even) in a wild, out-of-control fashion, as the water vapour feedbacks kicked in, tripling the initial warming that came from the gigatons of poisonous carbon dioxide pollution that we’ve spewed (spewed, I tell you) into the atmosphere over the past decade.
I was a little surprised at what I saw. Read more… »
Thanks to those who advised me of this amazing email from the Climategate 2 collection, either through comments here or private email. It concerns the pre-1930 cooling of the New Zealand temperature record, and makes food for thought, especially for those supporting NIWA, Salinger and the increasingly shaky AGW story. Although it’s more of a novel, and a bad one at that, with gaping holes in the plot and evidence so carelessly thrown together it fools nobody. Now, as many of us feared was the case, comes evidence that the NZ temperature record has been applied to far more places than where it was observed. We now know it was stretched over far-flung places it was never intended to go. This is the worst result possible.

from: “Tim Osborn”
subject: New Zealand summer temps
just a quick Q before I go to bed!
I’ve just updated the IPCC paleo chapter Southern Hemisphere plot where we
showed, amongst other things, Ed Cook’s New Zealand TRW reconstruction,
with CRUTEM2v Jan-Mar smoothed temperatures.
For my update I’ve used CRUTEM3v, expecting them to be rather similar but
with a few more years on the end.
But the pre-1930 temperatures are now very different, being much cooler
(by > 0.5 degC for a 25-year low-pass mean) in CRUTEM3v than CRUTEM2v.
Previously they had been, on average, near or even above the 1961-1990
mean, now they’re at -0.5 degC.
Is this a result of some homogenization work on New Zealand summer temp
data? Or just some random artefact of minor changes somewhere?

Errors in the new 7SS
The shocking breakthrough in our audit is that NIWA didn’t use the adjustment method they said they would use. Barry Brill, chairman of the Coalition, released an overview entitled New Zealand Unaffected by Global Warming (pdf, 1.3 MB). The discovery that the country hasn’t experienced global warming is another startling finding. In Chapter 8, on page 24, he identifies nine criticisms of NIWA’s newest 7SS. These multiple defects destroy the credibility of the 7SS as a source of the NZTR. Read more… »
There has been no significant global surface warming this century, yet experts say that temperatures rose during the first decade, becoming seriously hot. Hotter than ever before, in fact. For example:
Past Decade Warmest on Record, NASA Data Shows
The decade ending in 2009 was the warmest on record, new surface temperature figures released Thursday by the National Aeronautics and Space Administration show.
The agency also found that 2009 was the second warmest year since 1880, when modern temperature measurement began. The warmest year was 2005. The other hottest recorded years have all occurred since 1998, NASA said.
James E. Hansen, director of NASA’s Goddard Institute for Space Studies, said that global temperatures varied because of changes in ocean heating and cooling cycles. “When we average temperature over 5 or 10 years to minimize that variability,” said Dr. Hansen, one of the world’s leading climatologists, “we find global warming is continuing unabated.”
But the only thing continuing “unabated” is the linear trend line — it’s still going up, and its slope hasn’t changed. “It’s all right. Only the data show a decline.” Read more… »
Here in New Zealand, the NZ Climate Science Coalition has battled for several years to understand the national temperature record and get the data released that lies behind it. Now we battle to correct it.
Because NIWA, in “reconstructing” the record, manages miraculously to lower past temperatures and increase recent ones to create a spurious warming that overstates the actual national warming over the last hundred years by 168%!
We’ve told NIWA about it and we’ve sent them our report that proves it, but they refuse to acknowledge our finding, much less explain themselves. It is a national disgrace which our newspapers, magazines, radio stations and television channels strangely refuse to investigate.
The warming is truly man-made, for it hasn’t happened in the real world, it has been created only by the adjustments.
Now, from C3 Headlines, we learn that an even more invidious process has been going on in the United States. Read more… »
This is surely too good to be true for the warmists.
In the last few days of a failing international conference, here’s a paper carrying strong confirmation of global warming. It’s not attribution, of course, but nobody will notice that. Proof of warming is enough to tweak the guilt nerve.
The Washington Post says:
The global temperature series is one of the clearest pieces of evidence that the planet is heating up. Over the past century, it’s easy to see from, say, NASA’s data that surface temperatures have risen dramatically. But there’s also a fair bit of short-term natural fluctuation from year to year, which can sometimes obscure what, exactly, is going on.
Earth’s temperature has never been taken, actually
A story, Analysis confirms global warming data, accounts for urban heat islands, appeared in the Science Media Centre (SMC) on 21 October. I missed it then, but it’s been brought to my attention in correspondence within the Climate Science Coalition.
A member saw the SMC story and commented:
Wratt and Renwick are quick to assert that this non-peer-reviewed temp study reinforces their suspicion that UHI is an insignificant factor. They both refer to numerous other authorities. I thought the leading paper supporting this view was Phil Jones’ China study of about 1991, which he has recently admitted to be based on a mistake. Are there any others which debunk UHI?
This raises several interesting elements which I’d like to follow at some time, but it also prompted this succinct analysis from the evergreen Dr Vincent Gray, who responded: Read more… »
Viscount Monckton of Brenchley opened his debate at the National Press Club in Australia two days ago by reminding his audience that England not only took the Ashes off Australia, but also held on to them in the next rematch. He said: “I just thought I’d rub it in.” Then he proceeded to take his cudgel to his feeble debating opponent.
Economist Richard Deniss must be no intellectual weakling, but he gave the impression of not knowing where he was, so he said the things he normally said. Which usually works, because his normal audience has heard them before and agrees with him. But here, he floundered and had no idea what he was doing. Read more… »
There is no statistically significant warming trend since November of 1996 in monthly surface temperature records compiled at the University of East Anglia. Do we now understand why there’s been no change in fourteen and a half years?
Well, yes, because “blame” for this interruption in warming has been placed on sulphates emitted by China’s power stations zealously burning coal. Hasn’t it?
Has this hypothesis been tested? No. Can it be tested? Yes.
Most of the aerosols are in the northern hemisphere, and there’s little mixing of air between the hemispheres. Reason tells us that the northern hemisphere should be cooling and the southern hemisphere should be warming.
Well, go on, this is the big test, look it up. Read more… »
The official New Zealand Temperature Record is made up of historical temperature readings (raw data) and NIWA’s adjustments. Both of those components are unreliable.
The 169-page Report on the Review of NIWA’s “Seven-Station” Temperature Series, or the Review Report (RR), published by NIWA in December 2010 devotes very little space to that bane of climatologists — the urban heat island (UHI) effect. It has been long recognised that air temperature readings taken in towns and cities are affected by the heat absorption of concrete and tarseal surfaces; by exhausts of vehicles, aeroplanes and air-conditioners; and by structures which deflect wind and confine humidity.
Because a “heat island” is not representative of the wider region or country, most climatologists try to give them a wide berth. Wikipedia says that “the temperature difference between urban areas and the surrounding suburban or rural areas can be as much as 10°F”.
A similar enemy of the climate archivist is “shelter” — trees or structures which interfere with the thermometer’s normal exposure to wind or sun, and thereby cause distortions.
The mean temperature impacts of both UHI and shelter are typically gradual, but non-linear. They are hard to detect and almost impossible to correct. Most climate archivists simply omit any sites suspected of being contaminated by UHI/shelter. Read more… »
Those who provide us with the supposed Mean Annual Global Temperature Anomaly (graph shown below) treat the annual points in their graph as if they were constants. The points on the graph do not represent actual observations. They are processed versions of actual observations and they are subject to statistical uncertainties.
The latest CRU paper to calculate these uncertainties is Brohan, P., J.J. Kennedy, I. Haris, S.F.B. Tett, P.D. Jones (2006). “Uncertainty estimates in regional and global observed temperature changes: a new dataset from 1850.” J. Geophys. Res. 111: D12106. doi:1020/2005JD006546.
This paper combines many sources of uncertainties and the final figures vary from year to year, but are typically about ±0.2 ºC on a 95% confidence basis. Some versions of their graph include these figures as “error bars” attached to the data points.
Brohan et al even admit that they do not include “unknown unknowns”, even referring to the internationally recognised expert on this subject, Donald Rumsfeld.
It is surprising that they have left out of their discussions the most important source of uncertainty in their figures, one which is “known” to every person who has studied stratistics. It is the uncertainty which arises every time you take an average. Read more… »
Official temperature records have been maintained in New Zealand since shortly after European settlement began in 1840. Throughout the ensuing 150 years, mean temperature levels appeared to remain stable. But NIWA (the responsible Government agency) has recently questioned the historical record, suggesting a long-term warming trend may have been hidden in the data.
Publications from 18681, 19202 19603 and contemporary records4 indicate that mean temperatures in New Zealand cities have not significantly changed since records began (Tables 1,2,3). Degrees Fahrenheit in the early figures have been converted to degrees Celsius. Read more… »
Temperatures dishonestly twisted
stasis: Latin; to stand; inactivity.
There is a simple trick by which the recent non-rising temperature record is pretended everywhere to be soaring dangerously.
A merry wee post at Treehugger put me on to this handy table of figures from the National Oceanic and Atmospheric Administration (NOAA) State of the Climate report for 2010. The figures come from the National Climatic Data Center (NCDC) and show the top ten average global temperatures since 1997. I started thinking about them.
Notice that the table shows your (US) tax money at work — public scientists toiling for the good of their fellow citizens, finding never-ending practical uses for the torrent of objective science pouring from publicly-funded institutions, laboratories and universities. A process which no doubt repeats itself in progressive democracies around the world. Read more… »
NIWA, listen to this, it’s amazing
On December 1 last year, we wrote about Bryan Leyland’s prediction of significant cooling before the end of the year coming true. You can see from the chart exactly what happened. Not only that, it would appear that the temperature has not finished going down yet.
This remarkable forecast, now some eight months old, comes out of a 2009 paper showing a lagged correlation between global temperatures and the Southern Oscillation Index (SOI), calculated from fluctuations in the air pressure difference between Tahiti and Darwin, and indicative also of the start (and the state) of a La Nina (as now) or an El Nino. This correlation is a lot more convincing than comparing global temperature with CO2 levels! Read more… »
The “Seven-Station Series” (7SS) constituting the official New Zealand Temperature Record (NZTR) is analysed and compared with the Southern Hemisphere (SH) temperature record using an interesting new data analysis technique called Empirical Mode Decomposition (EMD).
Analysis of temperature trends usually employs extrinsic data smoothing techniques such as regression, moving average and Fourier filtering, but there is a more appropriate technique available.
Empirical mode decomposition (EMD) is an intrinsic data analysis technique now being used across a number of disciplines, including climatology. You can find out more from these two background papers: On the trend, detrending, and variability of nonlinear and nonstationary time series (Wu et al., 2007)(pdf) and Analysis of Temperature Change under Global Warming Impact using Empirical Mode Decomposition (Molla et al., 2007)(pdf). If you want to study EMD in detail, there’s a lot of help available — even a free command line utility.
EMD uses a sifting algorithm that filters the data until an overall adaptive trend (monotonic residual) is revealed. The first paper linked above shows how a decadal trend was also extracted from the global record but the 100-year 7SS time-frame used here is too short to do the same. A longer 7SS record would probably reveal an intermediate decadal trend similar to that presented plus an overall trend that cannot be extracted (by this author) from the 7SS at its current length.

The CCG has responded to this happy news by issuing a press release.
NIWA, where are you?
The Southern Oscillation Index (SOI), according to the Australian Bureau of Meteorology, is calculated from the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin.
In July last year three climate scientists published a paper in the Journal of Geophysical Research. “Influence of the Southern Oscillation on tropospheric temperature” concluded that nature, not man, was responsible for “recent global warming.”
The paper, by John McClean, Chris DeFreitas and Bob Carter, shows that what the SOI does now, the temperature will do in between five and eight months’ time.
Simple. But does it work to predict global temperatures? Read more… »
On NIWA’s web site their discredited graph of New Zealand’s temperature history still clings to life. Look at it — it seems to flutter its wiggly lines, hoarsely whispering: “believe me, believe me.”
This is the graph NIWA’s lawyers completely disown in a declaration to the High Court that it is “not an official graph.”
Why do they continue to display it? It lacks any kind of scientific justification or integrity. The main authority describing its methodology has never been cited, never been copied, never been peer reviewed.
None of the seven weather stations (only seven for the whole country, out of hundreds?) showed significant warming in their raw readings. But six have had a “temperature rise” imposed by adjustments, 90% of which served to create warming.
Have NIWA no shame? They should have withdrawn this spurious piece of scientific chicanery months ago. Instead, it remains there to lie to our children.
We’re still waiting for the new version, reviewed by the Australian Bureau of Meteorology, promised by NIWA last March. Will we see it before Christmas 2010? When we finally do see it, will it still show nearly a degree of warming over the 20th Century?
If it does, how will they justify that? If it doesn’t, how will they face their public, for what will happen to their claims of anthropogenic global warming?
There’s a great deal hanging on the new version of this innocent-looking graph. And I mean “hanging.”
There’s some excitement around blogdom with the Australian Bureau of Meteorology (BOM) apparently questioning the UHI adjustments it’s made to the temperature record.
The actual press release
But the story is proving difficult to pin down. I’ve located the BOM Media Release of 13 October, 2010, which says (emphasis added):
Wednesday 13 October 2010
If you thought our cities are getting warmer, you’re right.
Bureau of Meteorology researchers have found that daytime temperatures in our cities are warming more rapidly than those of the surrounding countryside and that this is due to the cities themselves. Read more… »
Barry Brill rips into NIWA’s showcase paper on the Hokitika weather adjustments — the one intended to demonstrate that data adjustment is science rather than art. - Richard Treadgold
In February 2010, NIWA published a showcase paper titled Creating a Composite Temperature Record for Hokitika, offering details of adjustments it made to the NZ Climate Database for the Hokitika Airport weather station — one of the “Seven-station Series” (7SS) which makes up the official New Zealand temperature record.
The NZ MetService measurements for Hokitika cover the 20th century and display no significant linear trend up or down. The temperature recorded here in 1900 was 11.8°C, while 2008 was 11.93°C, and the 30-year average from 1971–2000 was 11.74°C.
The NIWA-adjusted version, on the other hand, shows a linear warming trend of 1.3°C, largely brought about by downward adjustments in the Hokitika temperatures in the first half of the century. The justification for those adjustments has been cited repeatedly as being an Appendix to a university thesis submitted in 1981 (see “The Salinger Thesis”).
The Hokitika details were made public as a worked example of the adjustments that NIWA has made to all seven weather stations in the 7SS, in consequence of the Salinger thesis. Accordingly, the credibility of the entire project stands or falls on the strength of reasoning advanced for the Hokitika alterations.
But that reasoning is not sound. Read more… »
It would be easy to overlook this little paper, but don’t be tempted! In the context of “NIWAgate”, our legal move against NIWA and world-wide action to clarify temperature records which seem to bolster claims of unprecedented warming, Barry Brill’s revelations are dynamite! We asked NIWA what changes they made and why. NIWA said we’d find it in certain papers. Now, for the first time, Barry shows decisively that those papers don’t contain either the changes or the reasons they were made. NIWA’s duplicity is indisputable. Is this the behaviour we want from our premier climate research agency? - Richard Treadgold
The weather station at Lincoln is one of the seven which make up the official NZ Temperature Record over the past 100 years. It shows a strong warming trend as a result of downwards adjustments which NIWA made in respect of the pre-WW2 period. But those adjustments rely upon a curious methodology which is not supported by any of the peer-reviewed literature.
The original temperature data for the Lincoln weather station – recorded by the NZ MetService, and now downloadable from NIWA’s official Climate Database – shows no warming trend over the past 100 years.
More adjustments that cause warming
The Schedule of Adjustments (SoA) prepared by Dr Brett Mullan and posted on the NIWA website on 9 February 2010, shows five downwards adjustments in the period 1881-1943 and two upwards adjustments during 1944-75. All seven alterations to the NZ MetService climate database are trend-favourable, and comprise the sole source of the reported warming trend. Read more… »
A survey begins
When we published our paper Are we feeling warmer yet? last November, criticising the Seven-station Series (SS), NIWA quickly produced what they call the “Eleven-station Series” (ES) to counter it. They went to the trouble of asking Dr Jim Salinger, recently dismissed and author of the original national temperature series, to help them create it, which makes us realise that nobody at NIWA understands how he produced the original figures.
According to the NZ Herald, Jim specially selected the stations for the ES.
Some people would be impressed by that news, but others find their antennae stiffening at the idea of “specially selecting” data for any reason. It might be justified, but then again, it might not. The situation calls for careful study. So what has happened? We can say a few things about it.
Scientists in the Coalition have had a look at the new series and found problems with it. Read more… »
While on the subject of awkward, unanswered emails, let me pass on a message I recently sent to Dr James Hansen, the scientist widely famed as the “father” of global warming. I still hope he will offer some explanation.
4 March 2010
Dear Dr Hansen,
The Climate Conversation Group and I have become interested in the very meaning of “taking the temperature”, calculating the so-called “average” temperature for a place and a region and the meaning of doing so. I have just seen your web page [The Elusive Absolute Surface Air Temperature (SAT)], discussing these and related matters. It is an interesting and informative page.
You say there is no agreed method of measuring surface air temperatures and, in fact, there are numerous practical and theoretical obstacles to ever achieving such a measurement.
There is a very obvious question raised by that discussion. We are interested to know why, if it cannot be done, do you do it?
Climate Conversation Group
Most people take for granted that New Zealand’s surface air temperatures (SAT) have gone up over the last century. But is that true?
NIWA’s official graph of the national temperatures is well known. You can get it from their web site. By the way, if you go there, let me know if you think they’ve recently stretched the image laterally; it is definitely wider than before — even the text is obviously stretched sideways. Could they be trying to make the vertical change less prominent and thus reduce the apparent slope of the trend line? What goes through their minds at NIWA? Anyway, as copied a few months ago, and so a little different, it looks like this:
You should be aware that the Climate Conversation Group and the NZCSC have delivered a rip-snorting criticism of this graph, so we don’t agree with it even for a moment. Now I will raise further objections to NIWA’s graph because it contains features inconsistent even with NIWA’s own conclusions. Read more… »
NIWA keep talking about various reasons to adjust the official New Zealand temperature readings. They say one must account for changes in location, exposure, urbanisation and instrumentation. For some reason they continually harp on about the altitude difference between Thorndon and Kelburn (Wellington).
But it is empty talk, because they have never made changes for those reasons. Are you listening? People of New Zealand: scientists from the National Institute of Water and Atmospheric Research (NIWA), your country’s publicly-funded, premier environmental research organisation, have lied to you and continue to lie to you.

John Key: you must bring NIWA to heel
The Waikato Times yesterday wrote:
Niwa principal climate scientist Dr Brett Mullan said Niwa “had the original data, knew the method of the calculations, and we have the answers”. There was “no scientific issue from our perspective”, and Dr Salinger’s work had stood the test of time.
So what are the adjustments
The NZ Climate Science Coalition began asking NIWA for the adjustments to the national temperature record in late November.
NIWA have told us where we could find the adjustments; we searched for them where they told us to search; the adjustments are not there.
NIWA have said: “We have the methodology, it’s in a student’s thesis [and other sources] from 1981, just read it.” The Coalition never asked for the methodology, we asked for the adjustments, but we looked anyway. Read more… »
What’s going on?
NIWA goes to a lot of trouble to warn us about the coming “climate change” causing warming between 0.7°C and 5.1°C by 2090. But I can reveal evidence that our top climate scientists don’t believe this.
Should New Zealanders expect significant warming for the next 80 years? You might be surprised to learn — especially if you’re following the discussions here — that scientists with NIWA, whose job is to research the climate, tell us we already haven’t had any warming to speak of for about 60 years and we won’t get serious warming in the future.
Now that’s not the message we normally get from government scientists! Read more… »
The paper we published last November continues to attract attention. The sceptics like it since it seems to refute any warming in New Zealand and the warmists like it since it seems to present a loutish, unscientific punching bag.
The truth lies more moderately somewhere in between.
The sceptics shouldn’t look to our paper to refute local warming, because it doesn’t. It presents no evidence on the quality of the national temperature graph — it merely questions the data, expresses strong doubts about their accuracy and wonders what adjustments were made to them.
Salinger contradicts Wratt in writing
Those looking for a refutation of New Zealand warming actually need look no further than NIWA’s own graph of the New Zealand annual temperature series, which shows no significant warming since about 1950. Here’s a copy:
In confirmation of this, Dr Jim Salinger expressly claims that the NZ temperature increase over the last 50 years is only 0.3°C. In an email to Vincent Gray in 2006 he said:
A linear trend fitted to the data over the period 1950 – 2005 is equivalent to an increase of 0.4°C over that period (or 0.3°C fitting a trend to the last 50 years, 1955 – 2005).
That’s a far cry from 0.92°C over the last 100 years, which is what David Wratt last claimed. The first 50 years must have been scorching! Read more… »
I’ve just come across this video of Godfrey Bloom, Member of the European Parliament for Yorkshire. He was speaking in Strasbourg during the debate on the outcome of the Copenhagen summit on climate change when he gave this furious tirade against the belief in global warming.
The surprise for us was that, near the end, announcing that the New Zealand temperature database was “fraudulent”, he suddenly brandishes a copy of our report, Are we feeling warmer yet? It’s a dramatic moment!
So how about that, then?
Regular readers will know that we asked NIWA how they adjusted the NZ temperature series. In reply, they distracted, deceived and disparaged us. We checked what they told us and it was false. They lose.
They admit they never had the temperature adjustments we were asking for. Why didn’t they just say so in the beginning? We and the NZ public await an apology for their dissembling.
They’ve done the hard thing and admitted the truth. So the good news is they can now get on with some real science. They say they will “recreate” the adjustments. Whatever they mean by that, it must be an improvement on trying to denigrate us when we ask for information. It is also good that they reexamine the 30-year-old claims of warming that wobble now they lack any scientific support. In fact, there is evidence they are false. More on that later. Read more… »
NIWA blundered in not keeping track of some important records that justify the country’s warming since the 19th Century, even if it inherited the problem from its predecessor in the Met Service, or the early behaviour of Jim Salinger, who did the work. It blundered again when, instead of being honest, it attacked the CCG and the NZCSC when we asked to know the Schedule of Adjustments.
Now NIWA has admitted in writing that it lost the original data. This settles our original question for the moment and sets them free to go about repairing the situation. Their general counsel, Tim Mahood, made the admission a few days ago, and here’s the letter to prove it.
The NZ Climate Science Coalition had asked NIWA under the Official Information Act last December for the details of the adjustments. This is the original request.
Finally, here’s the hard-hitting letter the Coalition sent back to Mr Mahood, setting out the defects in his official OIA response the day before. Have a look at it — it’s dynamite.
Now we’re waiting for them to finish re-creating the adjustments to the NZ temperature record and to post them on their web site. They told us today it should happen this month. We’re on tenterhooks and can’t wait to have a look at it.
A month ago, when Hot Topic was berating us as unscientific and demolishing our case against NIWA, how many people thought our request was unjustified? How many thought NIWA could do no wrong? How many will apologise to us? Yet who has proved truly scientific? Who has helped to actually improve New Zealand’s temperature record?
For that will be the long-term result of our efforts. What a wonderful thing!
Having (no doubt painfully) admitted to losing Salinger’s working documents, NIWA is now free to pick up what old records it has and work on them afresh. Without the confession the old records must have languished untouched, their taudry reputation defended less and less vigorously by an organisation tarnished by its neglect of verity. A new spirit of honesty will invigorate the place, for truth sets everybody free. The result must be a more accurate dataset and more confident predictions for the future.
I wonder what Hot Topic makes of that?
NIWA have published misleading material on their web site and seem to have advised the Minister for Climate Change Issues to give evasive answers to questions in the Parliament.
For those unfamiliar with the story: NIWA keeps raw data for the national NZ temperature record and makes it available on their web site. The Climate Conversation Group and the NZ Climate Science Coalition conducted a joint study of the temperature record, researched by a science team and published on 25 November under the title Are we feeling warmer yet?.
But we’re only asking about the weather
That study demonstrated that the official graph does not represent the raw temperature data. NIWA told us that adjustments have been applied so we’ve asked for the details. So far they obfuscate. We don’t know why they refuse to disclose what the weather has been.
We conclude that NIWA’s response to our enquiries has been defensive, obstructive and oddly disparaging.
The Hon Rodney Hide became concerned about deteriorating standards in public science and asked in the Parliament whether the Hon Dr Nick Smith would require NIWA to release the full data for the official NZ temperature record. On the last possible day for answering, Nick finally replied: “You must ask Wayne Mapp; he’s the responsible minister (for Research, Science and Technology, the portfolio that covers NIWA).” We won’t get any Parliamentary questions answered now until well into the New Year, so Nick Smith has caused a considerable delay in getting this information to the public.
Gratuitously, he added: “I would note however that the NZCSC have had this information since 2003.” He hoped that little factoid would hurt the Coalition’s reputation, but it won’t, although it might hurt his own — because the Coalition didn’t exist until 2006.
See the email, they said, but they deceive us
NIWA say that the Coalition have had all the information needed to reproduce the official graph since 19 July, 2006, when, they say, “NIWA advised NZ Climate Science Coalition member Dr Vincent Gray” of the need for adjustments and gave him a couple of examples. Dr Gray has located an email of that date and we can now reveal that it was from Dr Jim Salinger, not NIWA, it was not addressed to the Coalition and did not mention the Coalition.
It was sent just a few weeks after the Coalition was created, before they ever discussed the national temperature record. Dr Gray tells us that and other emails before and since were not official communications on either side — they were letters between two scientists who had known each other for years.
But most significantly the email does not give details of the adjustments made to the temperatures, nor does it give the information required to derive the adjustments. Dr Salinger just discusses the changes in a general way and gives a few examples and that’s all. NIWA’s assertion that that email contains the requested information is not supported by reading the email. Read more… »
Steve O’connor is a senior geologist who has studied paleoclimate for 40 years. He lives in the circulation area of the Taranaki Daily News, which today published some astonishing comments from one Trotter. I am, unfortunately, unable yet to confirm the Taranaki Daily News item or give a link to it, but I am re-publishing Steve’s letter anyway, because it is the best summary I have read of the central anxieties arising from the global warming scam.
UPDATE 14 Dec 8:30 am: To give you just an outline of Trotter’s complete abandonment of evidence-based science, his denial of the right to free speech and his denial of evidence-based doubts of man-made global warming, here are the concluding comments from his Dominion article, titled “In the war for nature, the deniers are traitors”:
“There will, of course, be people who whisper that the enemy isn’t really our enemy … In 1940, England was full of such whisperers. The British ruling class, in particular, was riddled with defeatists, Nazi sympathisers and traitors. Back then people called them “Quislings” and “Fifth Columnists”. If, therefore, the battle against climate change has to become the moral equivalent of war, with all the sacrifice that war entails, then climate change denial must become the moral equivalent of treason. Over the top? No. The stakes really are that high.”
It is sobering to reflect that, a mere 65 years after World War II, which killed so many of our finest young men as they defended the freedom we still live in against the oppression from without of the advancing fascist barbarians, we are about to subjugate ourselves from within. For the remaining vestiges of that freedom are about to be crumpled in the unelected fists of the most devoted, socialist, totalitarian, “environmentalist” bureaucrats the world has ever produced, justified solely on the grounds of non-existent evidence of man-made climate control.
A menacing interpretation
When I first encountered, a couple of years ago, this menacing interpretation of the approaching “carbon crisis” I scoffed. It was alarmist nonsense; outlandish that anybody would do such a thing; an imaginary conspiracy from the paranoid—surely the movement is based on the science of the enhanced greenhouse effect?
