All the posts on NIWA’s web site criticising the Coalition, me and the study we published have just been removed. The articles defending NIWA’s performance regarding the national temperature record have also been removed from the web site.

Is this the start of something fresh and open from the Board of Directors?

Peeling the onion in the Parliament. The NZ Parliament Building in the capital, Wellington. The attached “Beehive” (affectionate local name bestowed for obvious reasons), provides office accommodation for MPs and staff. Questions asked in the Parliament of ministers of the Crown must be answered unless they concern “operational matters”. Like the onion, everything associated with the Parliament has many layers. As we make our way through the Parliamentary questions it’s surprising what is being uncovered.

We’re working through several answers from the Hon Wayne Mapp, Minister of Research, Science and Technology, concerning questions posed by ACT about the National Institute of Water and Atmospheric Research (NIWA). Some of the answers are bombshells. One reveals that NIWA lost vital worksheets used by Dr Salinger in constructing the national temperature record.

The next question I’ll discuss concerns adjustments NIWA made to the national temperature record. ACT asked a simple question about them, which was this:

… how many of the years before 1950 had their temperature adjusted downward in the NIWA “Seven-Station” Temperature Series and how many upward; and how many of the years after 1950 had their temperature adjusted downward and how many upward?

A destroyed hard disk drive. When it’s in this condition nobody can retrieve the information. Does this represent NIWA’s reputation?

NIWA have admitted that vital original material used to prepare the official New Zealand temperature records was deleted. They do not say when it happened, but it means that, in contravention of time-honoured principles of good science, NIWA is no longer able to verify the work done by Dr Jim Salinger.

The news came in an answer to a written parliamentary question from ACT and comes as NIWA is under pressure to justify the so-called “seven-station” time series that forms the centrepiece of their evidence of long-term warming.

The Climate Conversation Group (CCG), in association with the NZ Climate Science Coalition (CSC), published a report last November into apparent irregularities in the New Zealand temperature record. Read more… »

A cold-blooded lizard has empathy and a sense of concern for its fellow creatures.

There continues such a stream of cold-blooded invective over at Hot Topic, one marvels they have the will to ignore the point for such long periods.

They discovered ACT’s questions in Parliament yesterday and have shared with the world the following pearls of understanding.

Gareth (after reading John’s first question): What “schedule of adjustments”? That’s just a term made up by Treadgold. Who writes your questions, John?

Picking up on that term is weak and quite ignores the thrust of the question. I didn’t make it up, but it’s jolly useful. James Renwick uses the term, so we’re in good company (or Renwick is).

Rob Taylor contributed: Evidently, ACT and NZ”C”SC are joined at the hip – one couple who truly do deserve each other!

Mindless twaddle.

password1: Speaker was ’sympathetic’ to the ACT’s member’s point of order. Transcript: [link]

Ah, some information!

Gareth: Hide’s supplementaries sound as though Treadgold wrote them for him. ACT are clearly hell-bent on supporting the CSC and CCG smear campaign. More fool them.

What’s wrong with me writing them (though I didn’t)? What smears? Show me a smear.

So, after this pointless arm-waving, what about NIWA not keeping a schedule of adjustments? You’re not enlightening us one bit, lads.

A question, a Mapp and a revelation.

Hide one, NIWA nothing

Question time in the House today was a revelation. You could see it, writ large and terrible, on Wayne Mapp’s face as he finally realised the depth of deception he’s been handed by his own department, the National Institute of Water and Atmospheric Research (NIWA).

It has been obvious for a while that NIWA has not taken the good minister into its confidence, and I hope that the Hon Dr Mapp went back to that department today and rapped some naughty NIWA knuckles. It is past time it happened.

Deception is the wrong approach to use on a Minister of the Crown. You might try it, and for a time you might succeed, but it will catch up with you. I would not be in David Wratt’s shoes right now for any price.

Dreadful display of ignorance

Wayne Mapp did not appear to know

• that the schedule of adjustments was not, in fact, contained in the voluminous references NIWA gave the NZ Climate Science Coalition (CSC)
• that there are reasons other than location changes to adjust temperature readings
• that the schedule of adjustments is not on NIWA’s web site
• that Salinger’s thesis is not publicly available
• the difference between the methodology of the temperature adjustments and the adjustments themselves
• that the documents cited by NIWA do not in fact exist on NIWA’s web site but are elsewhere
• that the famed schedule of adjustments does not actually exist

It was a dreadful display of ignorance by a Minister facing questions in the Parliament. Read more… »

The inter the face egg.

It’s hard to know what Mr Renowden is trying to say in his post attacking me/us. Entitled Egg/face interface for Hide and the climate cranks, it asks for an apology from us/me but fails to mention what for.

I’ll have a closer look soon and comment on it. But it looks like the same tiresome stuff, I fear, as we’ve dealt with already. NIWA have told us that they don’t have all the records to give us a full answer but they will reconstruct them and show us why the adjustments are justified. To demonstrate that, they’ve just released the adjustment schedule for Hokitika.

There’s no reason for us to apologise, but we have thanked them.

We (our scientists) are looking at the Hokitika adjustments. We’re also examining Salinger’s thesis. Finally. Hurrah. It’s catastrophically long so any opinion will be a while in coming.

Gareth’s rant has attracted a great many comments, a lot of them rambling off the topic, but too few of any value and, regrettably common at Hot Topic, too many of none.

The two versions of the official NZ temperature data — the NIWA graph in the foreground has been “adjusted” but NIWA doesn’t know how; the graph behind it shows raw NIWA temperatures since 1850; there’s no warming. Both graphs use official NIWA data, but NIWA don’t know what changes created the warming and, until they produce a replacement, there’s no scientific reason to accept that version. See larger versions of the raw and adjusted temperatures.

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… »

UPDATE 1 1st Feb, 11:16 pm: The second paragraph should have stated that Jim Renwick was quoted in the Herald, not Jim Salinger. My apologies; this has been corrected.

The unadjusted temperature readings from the seven weather stations NIWA selected for the official NZ temperature graph, presented as anomalies. Can they really not explain why their graph is different from this one? (Are We Feeling Warmer Yet? – NZCSC, CCG, 2009).

Heads must roll

Turning into farce

In an astounding admission of ineptitude, after their former arm-waving and expostulations of injustice, NIWA have finally confessed that they cannot provide the adjustments they made to the original temperature readings in the official NZ temperature record. Read more… »

The striking Tam O’ Shanter sea urchin. Examples like this were found along with three new species during a deep-sea survey of seamounts on the Chatham Rise in June 2009. NIWA’s research vessel Tangaroa explored the Chatham Rise, an area that stretches for 1000 kilometres from near the South Island eastwards to the Chatham Islands.

In the NZ Herald yesterday morning came news that NIWA is “putting all of its temperature data and calculations on the internet”.

It’s been five weeks since the NZCSC request to NIWA’s CEO, John Morgan, under the Official Information Act; it’s only two months since we published our study critical of the handling of the NZ temperature record; and it is decades since Dr Vincent Gray, Dr Warwick Hughes, Dr Jim Hessell and others started asking Dr Jim Salinger for his data and calculations.

This is tremendous news and it is to NIWA’s credit that they are releasing the data. But one comment from Renwick strikes a sour and revealing note:

Yesterday Dr Renwick said that while he had no problem releasing the Niwa data he found it insulting to be singled out when, for example, medical and Treasury researchers were not expected to disclose all of their workings. “There is a real issue of trust here. The assumption is people like myself don’t know what we are doing or we’ve got some kind of agenda just to get research funding.”

He feels insulted? He should stop whining. Any discomfort Jim Renwick feels in being compelled to hand over to the public this public data is of his and his colleagues’ own making. NIWA is being singled out only because of its sustained intransigence over many years. Read more… »

NIWA (National Institute of Water and Atmospheric Research) has been accused of “propaganda posing as science” in its claim that the 2000s have been the warmest decade on record. The New Zealand Climate Science Coalition says the claim that the “noughties” decade is the warmest is based on a statistic for which the margin of error is far greater than the claimed warming.

The Coalition says it fully agrees with the criticism by Blue Skies weather forecaster Tony Trewinnard that NIWA’s own numbers show there is no long-term warming trend.

The warm decade claim is one of five by NIWA which amount to advocacy rather than science, and as such represents propaganda which should not be expected from a Crown research institute, especially one claiming to be based on science. The examples of advocacy are:

1) The warmest decade: NIWA principal climate scientist Dr James Renwick told newspapers that temperatures at seven key stations over the past 10 years were one-tenth of a degree above the 1971-2000 norm, adding “the next warmest were the 1980s, about 0.07°C above that normal, so it’s only a few hundredths of a degree difference”. Dr Renwick should know that a few hundredths of a degree is well inside the margin of error for temperature readings and is, therefore, meaningless. The Coalition says if Dr Renwick doesn’t know about margin for error he shouldn’t be in the job; and if he does know it, he has misled the public.

2) NIWA constantly claims that spot temperatures are just ‘noise’ and only long-term trends are important in climate science. NIWA’s statement notably fails to mention that the upward trend in the nineties has unexpectedly disappeared in the ‘noughties’.

3) Most of the warming in New Zealand occurred prior to about 1955, well before the build-up of atmospheric CO₂. There has been little or no statistically significant warming in New Zealand over the past 55 years. NIWA fails to put its information in its proper context.

4) Climate is always warming or cooling. There no evidence whatsoever that ‘climate change’ in New Zealand over the past 150 years is outside the expected range of normal climate system variability.

5) The NIWA press statement wrongly contended that 2009 was a year of warm weather extremes, when it is usually at pains to distinguish weather from climate. It dwelt on cyclones in the Pacific without mentioning the vanishing hurricanes in the Atlantic. It studiously avoided mention of the blizzards which disrupted the Copenhagen conference and are currently setting coldness records throughout the Northern Hemisphere. The entire piece is a classic example of the use of selective and misleading data.

The Coalition statement concludes: “Until NIWA responds to our request to come clean on the full extent of its adjustments to raw temperature data, exactly what adjustments were made, and why, any statement that institute makes about climate variation must be taken with a grain of salt.”
