NZ wind farm subsidies

NZ wind turbine

Subsidies? In New Zealand? For wind power?

 

A conversation was under way here, sparked by my post on Germany’s “new dark age”. A reader (Andy) posed the question:

“I am intrigued by the NZ wind industry, because it seems, on the face of it, to be just about the only example in the world that is not surviving on subsidies (other than the ETS, of course). Am I missing something here?”

Now Bryan Leyland provides the startling information that NZ wind turbines do enjoy substantial public subsidies. He laid them out for me. I’ll start with the smaller ones and shock you with the biggest at the end.

First, they don’t have to predict in advance what the output will be. Of course, this would be a practical impossibility, like predicting the exact rainfall next month. But we are immediately alerted to one of the most serious drawbacks of wind generation. Continue Reading →

CSC: NZ must not volunteer for another Kyoto

UNFCCC logo

by Hon Barry Brill

There are implications for New Zealand arising from the United Nations Framework Convention on Climate Change (UNFCCC) that will get down to business for the 16th time in Cancun, Mexico next week [this week – Ed]. While packing their bags for their departure on Monday, the New Zealand Ministers, Tim Groser and Dr Nick Smith, need to pause to consider what will be in the best interests of we Kiwis whom they will represent. They know already, in advance, that no decisions of any consequence will emerge from Cancun. Rather than seeking to bask in international acclaim by supporting tiny steps toward an uncertain and not yet fully understood destination, they should lead a call for a review of the science to determine, once and for all, whether there are valid grounds for the computer-modelled hypothesis of dangerous warming being caused by human emissions of greenhouse gases.

Unless and until science can definitely confirm that hypothesis, there is no point in allowing money to continue dominating the agenda, as the 193 countries in attendance try to reach consensus on a Long-Term Co-operative Action (LCA) agreement to reduce greenhouse emissions. Continue Reading →

Fighting climate change public insanity

picnic table and chairs set up in the sea

In the NZ Herald last Wednesday, David Venables, executive-director of the Greenhouse Policy Coalition, talked about world leaders at Cancun soon putting “the finishing touches to a global agreement on climate change.”

Why do we want such an agreement?

Though Mr Venables, oddly, leaves it unsaid, it is to reduce our emissions of “greenhouse gases” or “carbon” to halt what we now call “climate change.”

But is this enough? Will this stop climate change? No, it won’t, and there are two reasons for that: NZ’s tiny emissions and the eternally changing nature of the climate. Continue Reading →

World of sceptical questions unfolds…

Rodney Hide

We have been offered, dear reader, an outstanding opportunity to engage in climate activism.

A reader, Huub Bakker, commented yesterday on What’s left of the NIWA case, saying:

Where does all this leave the Government legally? Should all the previous conclusions be re-evaluated? Will the plastering job of the new NZTR be sufficient? Any thoughts from Rodney Hide, who I know reads this blog?

And this afternoon Rodney responded:

Amazing! And very disturbing about the state of science at NIWA.

What next? I am not sure.

Perhaps readers could suggest questions for the Minister Responsible for Climate Change Issues, Nick Smith, and the Minister of Research, Science and Technology (in Charge of NIWA), Wayne Mapp?

No other country can do this

That’s a remarkable offer, Rodney, and we’ll take you up on that, thank you.

Folks: let’s not underestimate either the significance of Rodney’s suggestion or the power of our questions. For overseas readers: Ministers of the Crown are under an obligation to answer correctly-phrased questions in the Parliament; they cannot decline. The difficulty is that you need to be a member of the House to ask the questions. Hence the importance of Rodney’s suggestion. Let us use it wisely.

Hot Topic semi-science now in the Herald

NZ Herald crest
Hot Topic logo

Now we have the NZ Herald echoing Hot Topic’s posts from Sciblogs. Man, the Herald have really burned their bridges on impartiality, haven’t they? By patronising Hot Topic they unquestionably declare their belief in the non-science of dangerous anthropogenic global warming.

Don’t expect any material from them in the near future to be critical of the now-established doctrine of climate change according to the IPCC.

Comments on poll uncover Hot Topic’s dearth of science

Yesterday, they published an article by Bryan Walker, one of Gareth’s support writers, Ask me why – polling the public on climate change. The first thing Bryan does is denigrate the organisation behind the poll; good one, Bryan, ignore the issue — go straight for the man.

Note also Walker’s disconnect from the real world where people must make a living:

But their notion of what constitutes appropriate measures is severely constrained by their determination to protect what they call the competitiveness of all sectors of NZ industry.

“What they call” competitiveness? He says that as though it’s a bad thing. Continue Reading →

NZ Herald ratifies outrageous rant

NIWA temp adjustments with scales of justice

Just four days after Brian Rudman’s diatribe against the Coalition, the Herald unleashed an opinion piece by one Sam Fisher. I’ve just discovered it but that’s no reason to let it stand unopposed.

I shall start at its rear end. His devastating conclusion:

In past years, the nutters were the ones with signs that said: “The world is ending.” Now, the nutters have the signs that say: “The world isn’t ending, it’s all fine.”

I agree wholeheartedly with this sentiment, for it is hard to fault. However, he omits mention of the sanity of those trumpeting the end of the world. So I would express it with a different slant, as it is on the masthead above:

For the first time in history, people shouting “the end is nigh” are somehow
the sane ones, while those of us who say it is not are now the lunatics.

Before that, he enlightens us with: Continue Reading →

To do good, the free will be bound

a bait ball

C. S. Lewis on Liberty

“Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive,” wrote C. S. Lewis, the Oxford/Cambridge scholar best known for his Christian apologetics and the Chronicles of Narnia book series. “It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron’s cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.”

May those toiling for the improvement of society in New Zealand and around the world give these words sober contemplation.

Improvement need not be bought with the loss of our freedom. Who would lead us will learn the difference between them.

(Thanks, Keith.)

A tale of two hemispheres

a brain of two hemispheres

Running this blog, people send me stuff.

My new friend Jim has sent me a wonderful graph that pits NASA against NIWA in a way most apposite for our stoush with them. Here’s the graph, showing basically that the Southern Hemisphere has warmed more slowly than the Northern Hemisphere:

temperatures of two hemispheres

This must be compared with the official NZ graph from NIWA.

official NIWA temperature graph

Jim said:

The Goddard Institute for Space Studies [GISS, a division of NASA] explains that the temperature increase in the Southern Hemisphere is less than the Northern due to it being mainly water and that water has a greater temperature inertia than land.

The NASA chart says that a 0.5°C increase has taken place in the Southern Hemisphere as a whole over the 20th century — well below the global average.

NIWA scientists, on the other hand, claim their data series is correct and that New Zealand is warming considerably faster than global averages. Why is a maritime country like New Zealand so anomalous to the rest of the Southern Hemisphere?

Which means that NIWA’s official national temperature series has some well-credentialled scientific opposition. Surely Wratt et al. will struggle to refute the well-muscled NASA without surrendering some humiliating ground. Continue Reading →

Why can’t scientists agree on Global Warming?

I couldn’t get to this meeting, but Ross Muir went along and sends us this report. – Richard

the real consensus - cartoon by Jo Nova

Last Thursday night the University of Auckland hosted an evening titled “Global Warming: Why can’t scientists agree?”

As both the title and the list of speakers made obvious, it was very pro-AGW, however I went along to see if there were any dissenters in the large audience and what sort of response they would get.

The speakers were: Prof Glenn McGregor (Director, School of Environment), Prof Roger Davies (Chair in Climate Physics, Physics Dept), Dr Jim Salinger (Hon Research Associate, School of Environment), Dr Anthony Fowler (Snr Lecturer, School of Environment) and Dr Mary Sewell (Snr Lecturer, School of Biological Sciences).

Handouts were made available on the way in. One by Prof Kurt Lambeck, the President of the Australian Academy of Science, on “The Science of Climate Change: Questions and Answers” and another large one, “Expert Credibility in Climate Change”, co-authored by Anderegg, Prall, Harold and Schneider (American and Canadian Universities). The latter contained graphs comparing the numbers of scientists/researchers and publications between the believer and non-believer camps. The graphs were so vastly different that I seriously doubt their veracity. Continue Reading →

Nicks in the myths of time

Baby stars, as seen by the Hubble telescope

I want to revisit some false arguments fabricated ages ago by our critics: time-worn errors which need re-rebutting, because they are still surfacing. These smooth myths, one might say, are nicked all over with imperfections. And mists cover everything.

The main spurious argument holds that the Climate Science Coalition says there’s no reason to adjust the raw temperature readings. That is false: we think there are good reasons for adjustments. What we actually say is that NIWA has made changes but refuses to reveal what they are.

A related myth is that NIWA has given us everything we asked for — simply by releasing the net arithmetical adjustments to each station. The reality is that, first, a net change isn’t enough because there could be multiple changes at a station. Second, the number by itself is useless; any reviewer needs the reason for each change. This is what NIWA has refused to tell us, yet both bits of data are required for any independent assessment of the accuracy of the temperature record. Continue Reading →

Barrage of misinformation: can’t they read?

NIWA temp adjustments with scales of justice

Wow! What an explosion of nonsense.

Hearing some of the comments about our court action against NIWA, you could be forgiven for thinking that the Coalition was made up of stupid people.

But the stupid ones are those mouthing off a torrent of misinformation against us without reading what we’ve actually lodged with the High Court. I have time only for a couple.

Commentator the First

Gareth Renowden, of Hot Topic, was interviewed this morning on Radio NZ by Sean Plunket. He said, among other things, the following:

I’ve been following [the Coalition’s] rather weird obsession with the New Zealand temperature record very closely on the blog.

It’s not a weird obsession, Gareth, it’s a weird and impenetrable temperature record, which you would know by now if you had bothered to take a look at it.

… all that Bryan [Leyland] wants is already there. The raw data you can download from NIWA. The adjustments that are required have been listed by NIWA; the methodology for doing it is available in the peer-reviewed literature; it’s incredibly non-controversial to climate scientists and meteorologists that you need to make adjustments.

Gareth here offers three false statements (I still hesitate to call them lies, though he has made them before) and a diversion. Continue Reading →

Background to our application for judicial review

NIWA temp adjustments with scales of justice

The following sets out the background of the NZCSC’s application and provides some vital context.

The National Institute for Water and Atmospheric Research (NIWA) is a Crown Research Institute (CRI), contracted by the Government to be its sole adviser on scientific issues relating to climate change.

NIWA’s National Climate Centre is responsible for maintaining the National Climate database, mainly comprising records compiled by the NZ Met Service during the period 1853-1992. This archive finds its greatest significance in the New Zealand Temperature Record (NZTR), showing mean average surface temperatures throughout the twentieth century.

In 1999, the National Climate Centre adopted a “Seven-station Series” (7SS) as the basis of the NZTR. The stations (Auckland, Masterton, Wellington, Nelson, Hokitika, Lincoln & Dunedin) are geographically spread and considered to represent New Zealand as a whole. The 7SS graph and spreadsheet appear on NIWA’s website www.niwa.co.nz/news-and-publications/news/all/2009/nz-temp-record. Continue Reading →

Our Statement of Claim against NIWA

NIWA temp adjustments with scales of justice

1. NIWA has statutory duties to undertake climate research efficiently and effectively for the benefit of NZ, pursuing excellence and observing ethical standards, while maintaining full and accurate records.

2. The official NZ Temperature Record (NZTR), which is the historical base for most Government policy and judicial decisions relating to climate change, wholly relies upon a “Seven-station series” (7SS), adopted in 1999.

3. The twentieth-century warming trend of 1.0°C shown in the 7SS is dependent on the use of “Adjustments” taken by NIWA from a 1981 student thesis by J Salinger, a previous NIWA employee.

4. NIWA’s 1999 decision to rely on the Adjustments was a breach of duty as it did not:

• evaluate the thesis methodology or consider whether it needed updating
• discover that the supporting data and calculations had been lost
• undertake any check or peer review or require consent from the copyright holder
• maintain any record of the decision Continue Reading →

Dynamite changes to raw readings

What has NIWA done to the original raw temperature readings? What do the adjustments look like? I can do little better than to show them on a single graph.

NIWA temperature adjustments, before and after

This clearly shows two important things:

1. The original readings show a slight, insignificant warming.

2. The adjustments have the effect of cranking the older readings down so the trend is now one of strong warming. Indeed, it is 50% greater warming than the globe itself.

Just as our original paper showed, back in November 2009, New Zealand has indeed been the subject of man-made warming, but only by adjusting the figures. Still, to this very day, NIWA refuse to detail the adjustments they made and why they made them. Continue Reading →

High Court asked to veto NIWA graph

NIWA temp adjustments with scales of justice

In an unprecedented move, the High Court at Auckland has been asked by the NZ Climate Science Coalition to invalidate NIWA’s official national temperatures.

Papers filed last week by the NZ Climate Science Education Trust ask the High Court to invalidate the New Zealand official temperature record (NZTR) developed and promoted by the Crown Research Institute, NIWA. NIWA maintains temperature archives for the past century, and attempts to forecast temperatures for the next century. These records form the basis of NIWA’s scientific advice to central and local government on issues relating to climate change.

All manner of documents published by NIWA claim that NZ’s temperature rose over the last hundred years by 0.9°C, supported by their specially-adjusted readings from their specially-selected weather stations.

Around the world, temperature records have been coming under closer scrutiny as people have discovered quality problems and even outright dishonesty affecting their national temperature history. Continue Reading →

Naïve fanfare silenced by foot-in-mouth NIWA

An ancient foot in the mouth

Quelle surprise! Network PR have taken down the page proclaiming their work with NIWA on “how to position itself in the climate change debate” (h/t to Andy).

It was here, but now the page of case studies doesn’t even mention NIWA. Here is the Google cache version, just to prove we didn’t imagine this.

When a company ceases to trumpet what they perceive as a good piece of work, you know their hand has been forced. In this case, who but NIWA would be doing any forcing?

Network PR has produced a monumental piece of naïvety in disclosing details of its work with NIWA. Network’s principals knew of their client’s adversaries, for the very purpose of the education campaign they fashioned was to deal with criticism from them, but the desire to trumpet their effectiveness was too strong to resist. It was a wonderful divorce from reality, to fail to imagine the adversaries hearing of this news and making use of it against their client.

So much for Network PR. Good luck to them. Now, through the careless eagerness of their supplier to leverage new business from success, NIWA’s senior managers have had their plainly self-absorbed thinking lit by a dazzling public spotlight and naturally it shames them. There are two threads in their error.

First, the leadership decided to use NIWA’s public funds for other than public purposes. That is, the organisation would not benefit from coaching their staff in how to avoid answering questions, only the individual scientists might be spared the irritation, embarrassment or simply the shame of answering questions exposing their unscientific methods, conclusions and agenda. Continue Reading →

NIWA prefers spin to straight answers

Hypnotic spiral

A scandal is erupting over a PR firm – Network PR – employed by NIWA for months specifically to advise it on how to respond to “attacks” from the NZ Climate Science Coalition and blogs like this one.

Read the self-serving announcement from Network here. Network must have been bamboozled into ignoring the scientific questions, because if they heard how simple they are, they surely would have advised NIWA to just answer them.

NIWA’s difficulties spring directly from refusing to answer these questions. Why won’t they answer? Continue Reading →

Don’t lie to me Nick Smith — 1

Image from TV series 'Lie to me'

A CCG reader reported on Nick Smith’s presentation on the ETS last Tuesday (I’m not sure where, as I couldn’t see a Tuesday meeting in his published schedule) and mentioned his use of a combined CO2/temperature graph showing a good correlation (h/t to Bulaman). He mentioned its resemblance to the famous hockey stick graph of late 20th Century global temperatures. It deserves a separate post. He says:

The road show here on Tuesday was well attended and a polite reasoned session. The 2 cops in the back of the room after the Gore fiasco might also have moderated things a bit! The rationale for being in the ETS was effectively the precautionary principle jacked up to cost us $1.5 billion. The evidence was our hockey stick friend with CO2 and temp graphed together.

At the Royal Akarana Yacht Club presentation on Thursday which yours truly attended, the combined graph Smith showed us resembles the Mann hockey stick graph, but it is different. It comes from the UK Department of Energy and Climate Change; you can see it in a brochure at the NZ government Climate Change site. The brochures were handed around at the meeting.

This is the graph: Continue Reading →

Nick Smith on ETS in Auckland tonight

The Hon. Dr Nick Smith

Dr Smith will be at the Royal Akarana Yacht Club tonight, speaking on the Emissions Trading Scheme. The meeting begins at 7:30 pm.

I’ll be there. I encourage anyone of a sceptical cast of mind to attend also and together we can put some pointed questions.

Come early, introduce yourself to me (white beard, black jacket). We can support each other and the cause of truth.

NZ ETS missing its target

Cover of the book The Carbon Challenge

… or is it?

The National government is determined to fire up an emissions trading scheme (ETS) on July 1st, but a new study criticises it forcefully.

NZ sceptics, led by ACT’s John Boscawen, have for some months campaigned against the ETS on scientific and economic grounds, inside and outside the Parliament. But this study by two Victoria University academics – believers in anthropogenic global warming (AGW) – could do more to force a government change of mind than any protest action so far.

Since it comes from within the warmist camp, John Key, Nick Smith and their advisers will, or should, pay it close attention. For it expresses arguments made by supporters of government “climate” policy, so they will be more difficult to dismiss than those of mere “deniers” of “climate change” (whoever they are).

Wellington protest against the ETS

heading dog

Esther and Neil Henderson, the hard-working people behind Climate Realists NZ, want you to know about a major protest march at the Parliament aimed at ending the stupid Emissions Trading Scheme (ETS).

Tues 22nd June, Civic Centre, Wellington, noon — be early

Parliament Buildings

If you can be in Wellington to support the anti-ETS march on 22 June, please give this notice some prominence on your website and spread it around by email.

Please note some of the details have changed slightly from earlier notices — you should use the details given here.

Esther reports that so far they have had an excellent response from lots of people and they are hopeful of a good turnout on the day, with trucks and tractors from the farmers to add colour and noise.

Come along and help make it a “cannot-ignore” event for the politicians!

Below this point is a rough interpretation of Esther’s latest announcement. It’s rough because it didn’t take too kindly to the transition from Word to html. I should spend some time tidying up the html, but it looks quite funky and it does tell you everything you need to know, so I’m not touching it. Contact details are at the bottom.

PS: I did make one change to Esther’s notice. Since there is, strictly speaking, no such time as “12 pm”, I changed it to “12 noon”. I hope Esther forgives my impertinence and I hope they’re not intending to meet at midnight.

PM’s Chief Science Adviser must change — or go

Professor Sir Peter Gluckman

Here is a statement issued yesterday by Terry Dunleavy, Hon Secretary of the NZ Climate Science Coalition.

UPDATE 21 June: see end of post

Prime Minister John Key has been asked by a former National Party activist either to rein in his Chief Science Adviser, Professor Sir Peter Gluckman, or to change his title to more accurately reflect the professor’s global warming propaganda advocacy activities. Continue Reading →

Gluckman — great baby doctor but no climate scientist

The ODT reports Professor Sir Peter Gluckman’s speech last night (you’ll remember him, he’s the PM’s chief science advisor).

As expected, the speech seems to have been mainly waffle with few new facts or arguments.

However, the Professor informs us that New Zealand beech trees and swallows are feeling the heat. This is despite Phil Jones’ claim that there has been no significant global warming for 15 years and a slight cooling during the 21st century. It also betrays David Wratt’s claim that future global warming will be less in New Zealand because of the surrounding ocean. More pertinent is the fact that NIWA’s SSS and ESS don’t seem to detect any warming in this country during the past 50 years. So something else must be affecting the swallows, and Gluckman’s ‘science’ (the only factual line in the whole speech) is exposed as being wrong.

Apparently the public is “confused” about the science — “what we know and what we do not know” — and the confusion is all caused by “deniers”. But, Doctor, we have genuine questions… Answer our questions! Beginning with: what’s the evidence?

If Sir Peter gives the PM truly objective advice on climate science, why doesn’t he do the same in his speeches? I think he’s telling John Key just what he wants to hear about global warming, so it doesn’t have to be objective.

There’s more to say about this disgrace.

We’re alone in these trenches, Nick

The NZ Herald reports Nick Smith commenting at the National Party’s northern conference at Waitangi last weekend. He was subjected to some stern questioning about the ETS he insists on installing for us.

He likens the scheme to our contributions to overseas conflicts, reasoning in this way:

“The challenge I give back to you is: when our Anzac troops went to Gallipoli, and when we’ve got our New Zealand troops in Afghanistan, do we really think those New Zealand troops in Afghanistan are going to make a world of difference to the final outcome there?

“No, we don’t. But what we do say, as New Zealanders, and what those Anzacs said in the tradition of New Zealand, is we as a country believe in doing our fair share.”

Nick, the two situations are not comparable. It is ridiculous, one might say even desperate, to attempt to compare them. You see, overseas, we’re fighting with other people. We can actually measure what we do against their efforts.

But with the ETS, we’re not like any other country. Nobody has an ETS like ours. We’re entirely alone.

And we will make no difference to the climate.

Whatever you say it will cost us, it is too much to pay for an empty gesture.

We are cretins ruled by delusions

A set of measuring spoons

UPDATE 1: 26 May 10:45 am

So it’s starting. It’s becoming real. For so long just a pie-in-the-sky dream of climate activists wanting so much to save the world from our greed, selfishness and general all-round bad qualities, the grand plan for the Earth’s climate is at last about to take a material form.

The Herald tells us today: “Mercury Energy hikes prices to reflect ETS“. Wonderful. Now we get the higher prices we demanded in order to change the climate. Now we shall be poorer, but happier. Now we can relax. The world is being put to rights.

The Herald says:

The ETS is a government-imposed cost on all electricity and gas production that emits greenhouse gases, reflecting the total volume of greenhouse gases produced by the electricity and gas industries as a whole.

Once upon a time, dear reader, in far-off times when our forefathers were subjects of the King of England, or the Netherlands, laws were introduced to require accurate measuring of everything that was produced and sold by measure. Standards were introduced and strictly enforced to ensure none of His Majesty’s loyal subjects might be defrauded by the unscrupulous manufacturer or vendor. Continue Reading →

Ice, anyone?

A gigantic glacier

Hot Topic has just released a rant against Barry Brill’s article “Crisis in New Zealand climatology”, just published at Quadrant.

Readers here, waiting for NIWA to release the reasons for the adjustments to the official national temperature record, will be pleased to learn that Renowden has the answer so NIWA needn’t bother with all that scientific mumbo-jumbo.

First he quotes Barry’s article pointing out that the average NZ temperature in the 1860s was 13.1°C, the same as the average temperature in 2005. Renowden scoffs at this but does not refute it. I find that strange. He has no argument with those facts. He lets them stand.

Instead, he waves a book cover at us, showing melting glaciers, falsely insinuating that rising temperatures are the only reason for glaciers to recede. Continue Reading →

The warming that wasn’t

The official archivist of New Zealand’s climate records, the National Institute of Water and Atmospheric Research (NIWA), offers top billing to its 147-year-old national mean temperature series (the “NIWA Seven-station Series” or NSS). This series shows that New Zealand experienced a twentieth-century warming trend of 0.92°C.

The official temperature record is wrong. The instrumental raw data correctly show that New Zealand average temperatures have remained remarkably steady at 12.6°C ±0.5°C for a century and a half. NIWA’s doctoring of that data is indefensible.

The NSS is the outcome of a subjective data series produced by a single Government scientist, whose work has never been peer-reviewed or subjected to proper quality checking. It was smuggled into the official archive without any formal process. It is undocumented and sans metadata, and it could not be defended in any court of law. Yet the full line-up of NIWA climate scientists has gone to extraordinary lengths to support this falsified warming and to fiercely attack its critics.

For nearly 15 years, the 20th-century warming trend of 0.92°C derived from the NSS has been at the centre of NIWA official advice to all tiers of New Zealand Government – Central, Regional and Local. It informs the NIWA climate model. It is used in sworn expert testimony in Environment Court hearings. Its dramatic graph graces the front page of NIWA’s printed brochures and its website.

Rodney Hide nettles NIWA

A speech delivered by the Hon Rodney Hide, ACT Leader, to the Waikato Federated Farmers AGM, at Hamilton Airport Conference Centre, Hamilton, on Thursday, May 6, 2010.

Nettle needles

Self-inflicted wounds and sloppy science

Should New Zealand lead the world?

Of course, you say. We’ve done it before.

First country to give women the vote. First country to sign a free trade agreement with China. First up Everest.

Yes, we know what it is to be first. To be the one others want to follow.

But do we know what it is to be out on a limb? To jump the starting gun and be running alone? Well, we are soon about to find out.

New Zealand will be the only country in the world to enact a national, all-sectors, all-gases ETS. Just us.

The US won’t be, nor Japan, India or China. And Australia has just pulled out as well. Continue Reading →

The New Zealand Emissions Trading Scheme (ETS) is an unnecessary waste of effort and it will increase the cost of living for every household in the land. It starts by raising the prices of electricity and petrol by 5%. The purpose is to change the climate of the earth.

National seem intent upon launching the silly scheme on July 1st. There are about eight weeks to go.

Send an email expressing your opposition to this new tax to your local MP, to the Minister for Climate Change Issues (Nick Smith) and to the Prime Minister.

Write whatever you want to say, of course, but if you asked me to give you some idea of what to say, I would suggest this:

I oppose the ETS. I want you to delay, disable or defeat the ETS. If the ETS goes through in its present form with your support, don’t come crying to me when you don’t get re-elected next year, because I won’t be voting for you and I won’t care if someone else gets your seat.

The New Zealand temperature vexation

Well, is the country warming or isn’t it?

Here’s an article written by one of the scientists in the NZ Climate Science Coalition (we like to call him Rupert Postlethwaite). Rupert is as much a wordsmith as a boffin and we hope you enjoy his easy-to-read account of the controversy over our national temperature record. He transforms a potentially boring topic into a lively entertainment. Because it was written last year, it does not represent the latest twists and turns in the saga and the numbers are slightly different, but if you forgive those little lapses, he does give a good account of the basic issues. Especially, he makes the reasons for adjusting the temperature readings easy to understand. Feel free to let us know what you think of it.

Thermometer

So, about that Global Warming…

If someone were to ask you the question “Has New Zealand warmed significantly over the past 100 years?” you’d be excused for looking at them somewhat askance. Askew, even.

“Of course it has,” you’d reply, somewhat taken aback at the audacity of the query. You might at this point make some notes regarding the questioner, just in case. You never know.

“Just look at the data,” you’d respond. “NIWA shows it clearly on their site. You can see a graph showing how we’ve warmed a full degree over the past century. See?”

In the Parliament today, Chris Auchinvole asked Nick Smith (Minister for Climate Change): “Are claims correct that New Zealand is the first in the world to have an emissions trading scheme, and that it is just a tax for revenue purposes?”

And thus did Nick reply:

No, 38 countries have commitments under the Kyoto Protocol, and 29 of them, or three-quarters, already have an emissions trading scheme. Nor is the scheme a tax. Although consumers and businesses will pay $350 million in the first year of the scheme for their emissions, foresters will receive $1,100 million in carbon credits for post-1989 forests. Far from providing net revenue to the Government, the scheme is actually a cost to the Crown. There are 12,000 New Zealanders who, in good faith, planted trees on the assurances of both National and Labour Governments that they would receive carbon credits for those post-1989 forests. The emissions trading scheme honours that commitment.

But the facts are different from those presented by our Nick. Continue Reading →

Please listen to us Mr Key

It is significant that there are so many voices raised against the ETS.

a humorous ETS cartoon

Rodney Hide confirms this, saying that he has never received such a high level of public support on any other issue. He says Kiwis around the country are annoyed. They know there’s no need for an expensive ETS that will deliver no benefits whatsoever.

It behoves you to listen to us and very smartly do something about our concerns or next year you will find yourself back in the loneliness of Her Majesty’s Loyal Opposition. Our ETS will do nothing for the environment, will diminish the budgets of hard-working families and will require a monstrous create-nothing bureaucracy.

In addition, though the ETS purports to be based on movements of carbon dioxide into and out of almost every large-scale process in the country, there is no way to measure such movements. If you don’t believe me, ask your officials; uptake and emission of CO2 are based predominantly on computer models.

Since it can’t be measured, everyone can overstate with impunity the quantities involved and has an incentive to do so. Fraud is rife in the overseas schemes and there’s no reason to think it won’t occur here, too.

Because of our power generation structure, even the price of renewable electricity will go up because of the ETS, giving windfall profits of millions of dollars to the generators.

It’s too much to pay; and we refuse to stroke the over-anxious egos of comfortable, middle-class, socialist greenies.

Pay attention: We don’t want an ETS.

Pain of ETS will do no good

Power transmission lines at sunset

When will we fight it?

John Boscawen, Act List MP, today issued this press release.

Genesis Energy Confirms Price Increase

New Zealanders can definitely expect to have to pay more for power from July 1, with Genesis Energy CEO Albert Brantley’s confirmation before the Finance Select Committee today that his company “will recover the cost” of complying with the Government’s Emissions Trading Scheme, ACT New Zealand ETS spokesman John Boscawen said today.

“And it is not only the cost of electricity that will increase, but that of petrol and industrial processes as well. The cost of basic food items – such as bread and milk – will also rise as the increase in electricity filters through the economy,” Mr Boscawen said.

“Kiwi families are facing massive price increases and a lower standard of living for no other reason than the Government’s desire to be seen as a world leader heading into the Copenhagen summit.

“But the summit was a failure, and now New Zealand is the only county to implement an all sectors, all gases tax. Not one of our three major trading partners – Australia, the US or China – has implemented an ETS, nor are they likely to.

It is time the Government acknowledges that it is out of step with the international community, and puts the ETS on hold. The pressure on low-income families, the cost in reduced incomes and lost job opportunities is entirely avoidable. It’s not too late to stop,” Mr Boscawen said.

Taxing the air we breathe

No doubt the government is pleased finally to have found a pretext for taxing the very air we breathe. This makes taxation very simple and in future they can avoid straining their creativity trying to arrange for ever greater interference in our lives and increasing their regulation of innocent pleasures. This interference, restricting the innocent pleasure of breathing out, is superlative, for it comes closer to the tyrant’s dream of relentless restraint of the population than any measure before it.

But the price we are to pay for this folly is unacceptable. Continue Reading →

NZ’s Reisinger — God’s right-hand man

Dr Andy Reisinger

Dr Andrew Reisinger, Senior Research Fellow, New Zealand Climate Change Research Institute (CCRI), sits at the right hand of God. The god, that is, of the IPCC — Dr Rajendra Pachauri. Andy is head of the Technical Support Unit for the Synthesis Report group of the IPCC, and from that exalted position controls what the world’s national leaders get to know about climate change.

For he was responsible to his “core group” co-author Rajendra Pachauri for co-ordinating the drafting of the Synthesis Report for the Fourth Assessment Report (AR4). The SR is “the concluding summary of the IPCC’s most recent assessment of our current knowledge on climate change,” as Andy’s cv puts it.

That sounds like proper influence to me — real, transformative power. For what comes out of the IPCC’s Assessment Report (or more particularly the summary of it) goes straight into the ears of national leaders around the globe and they will act upon it. They don’t read the actual reports, so they won’t spot the differences between them and the summary. Neither will they fault the summary for themselves, because they are not scientists.

So they are necessarily at the mercy of the authors (or manipulators) of the Summary Report. Much has been said elsewhere about the politically-motivated alterations that were made to many of the IPCC reports. The reports are meant to represent the best of current scientific knowledge, but in practice they are watered down, uncertainties are grossly understated, certainty is claimed where it doesn’t exist and what the scientists said has even been reversed — without their approval.

The mother of all conflicts — of interest

NIWA guilty of propaganda posing as science

NIWA web site banner

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.”

Kiwis and icebergs — they go together well

This post has been in the works for several weeks now but it hasn’t lost its fascination. A story appeared in the NZ Herald on 8 November about the latest sighting of icebergs, which annoyed me for its references to global warming. But on investigating I discovered some interesting science.

Icebergs are beautiful

Let’s do something for the language
There’s no collective noun for icebergs (the situation is worse than we thought!). Here are some suggestions: a group, a herd, a glide, a float, a thunder, sizzle, swish, a gleam, a crackle or a slush? That has a lovely rhythm. Let me know your preference, or send in your suggestions. When the list is a bit longer we’ll put up an online poll.

The story is stale and the icebergs have melted, but two issues remain: The first is that there’s nothing new about icebergs floating past New Zealand. It doesn’t happen often, but evidence proves regular visits going back millennia. Believe it or not, we have photographs! Not of icebergs exactly, but where they’ve been… well, you’ll see, read on.

The second point is that NIWA scientists can be relied on to mention the magic words “climate change” any time they’re talking about ice, water, wind or weather and that, my friends, makes me angry. Continue Reading →

Flourish commerce, and let the country live

UPDATE: 1 Jan 2010. I found the “flourish commerce” phrase used by Pears Soap, certainly a more salubrious context than the one I knew it from, but this is the only image I could locate. It’s not legible, but it is there (the evidence is overwhelming; 48,000 national science associations can’t be wrong).

Pears Soap -

The inside of my grandparents’ white porcelain toilet bowl had the inscription, for the regular edification of we young boys controlling our aim: “Flourish commerce, and let the country live”, enlivened by the stirring sight of New Zealand’s and Great Britain’s crossed flags, in colour.

Written probably in about the 1940s, such frank promotion of commerce was non-controversial in the days before so-called “social welfare” had smuggled its obfuscating tenets into every area of life, until nobody knows where wealth comes from.

These days, forgetting what wealth is and how it’s made, we consider even schools and universities to be centres of production, in the same category as pig farms and steel mills, and we burden their transactions with a Goods and Services and every other sort of tax.

We failed to destroy our own productive capacity

It is fiscal misbehaviour bordering on the criminal to thus reduce funds needed for education, but nobody seems even to notice, much less to complain.

In the Christmas Eve edition of the Herald, Brian Fallow, Economics Editor, pontificates sadly over the failure at Copenhagen of developed nations to destroy their own productive capacity. Continue Reading →

NIWA’s obfuscation unequivocal — it’s worse than we thought

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. Continue Reading →

No assistance from NIWA

A mound of email arrived in my inbox over the last few days. Much of it relates to our attempt to get from NIWA the actual adjustments they have made to the national temperature record.

My first priority is to make an informal response to NIWA’s posts on their web site and to the parliamentary answers we’ve received. It’s important that the people who have trusted NIWA know just how they are pulling the wool over our eyes (or trying to) and refusing to cooperate. In fact, they are being far more obstructive than any publicly-owned utility has a right to be, and you deserve to hear the details of it.

A scientific study is under way right now to make a more formal response to NIWA’s obfuscation, but that won’t be finished until some time in the New Year.

My thanks to everyone who has contributed information or suggestions, but their sheer number means it’s taking longer to review them. Which means I’m also unable to follow up for now the new connections we’ve just made with the network of Climate Realists, run by the excellent Neil and Esther Henderson, of Gisborne. But we’ll get there!

The new interest in us, but more importantly in the evidence-based doubts about the truth of dangerous man-made global warming, is wonderful.

So that’s the reason I haven’t posted anything about NIWA’s completely inadequate answers to us. But it will come soon.

Firing squads at dawn

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?

NIWA squirms, but agrees to release adjustments

A momentous meeting took place last night (Wednesday, 9 December) at Parliament House in Wellington. This exclusive account comes courtesy of the Hon Rodney Hide, who was present.

The meeting was called two weeks back by Nick Smith so that MPs could be briefed by Dr David Wratt, Chief Climate Scientist, on the official NZ temperature graph published by NIWA on their web site, which Rodney Hide had posed questions about in the Parliament.

Knowing NIWA climate scientists would be there, Rodney invited Dr Vincent Gray, leading climate scientist, to accompany him as an advisor.

Gross discourtesy

But before the meeting could begin, the Hon Dr Nick Smith had a surprise for them. He ordered Rodney not to bring Vincent into the meeting. Nick said roughly: “It’s a private meeting of MPs and we do not wish to have outsiders.” But, showing a distinct favouritism, he allowed the outsiders from NIWA to remain. So why did he exclude Rodney’s adviser? Was it because Vincent has known the details of the New Zealand temperature records for more than fifty years? Was NIWA afraid of what he knows? If not, why did Nick Smith refuse to admit Dr Vincent Gray?

It was, of course, a gross discourtesy for Nick Smith to brusquely issue orders to a coalition partner in front of other MPs. But that’s just my opinion.

So Vincent Gray took his leave and subsequently Dr Wratt began his address. They sat through about 25 minutes of a description of the IPCC process, its committees, scientific writers and review procedures. David talked about the climate modelling that underpins the alarming climate predictions and it was quite unnecessary and very boring.

Sudden disorder

Finally there was a moment for a question. Rodney said: “I’d just like to take you back to the graph on your web site, the one with seven stations. Can I ask about that?”

There were sudden signs of disorder as David Wratt, with the other scientist (Rodney didn’t catch his name) interrupting from time to time, seemed immediately to become angry with the New Zealand Climate Science Coalition. He ranted on about their press release and they didn’t want to know this or that. Continue Reading →

No curiosity? Then be a journalist

This story is datelined London, December 1, and comes from the Australian Associated Press. It was posted on the web site of the Royal Society of New Zealand—behind a paywall. [Full article at the end.]

First: it is frustrating, suspicious and avaricious for our Royal Society to hide its “news” behind a paywall. How widely, really, does it wish the news to spread, when it publishes only to its members?

Second: the level of uninterest evinced by this reporter in the matter he is reporting is quite awe-inspiring. There is not the merest evidence of curiosity, investigation or the most rudimentary checking of facts.

Be a journo — or join our Royal Society

The main assertions in this story are inane, blatantly alarmist, undisguised advocacy and wrong. That the story is promulgated by our once-proud, independent, trustworthy and in particular scientific Royal Society is now a source of shame to all New Zealanders. There is no doubt that our Royal Society has abandoned, in respect of the global warming controversy, any pretence to objective investigation. It has instead adopted such a strong intention to champion the hypothesis of man-made control of the climate that it blinds itself to the necessity of finding evidence.

Their intention moves them to breach their founding principles. Look them up. Their behaviour is a matter of law, so it will give way, given enough pressure, to legal or parliamentary sanction. Swell, public opinion, swell!

Our Royal Society even helps champion, through web site connections, the blatantly alarmist web site Hot Topic, which routinely insults scientific sceptics asking reasonable questions with terms like crank, denialist and worse. We have come to expect that from the likes of Mr Renowden and his bigots, but the support for it from the scientists of the Royal Society is reprehensible. It is scientific misbehaviour.

Here is a sampling of the AAP story’s errors, inadequacies and naked prejudice. Continue Reading →

Wise man: same within and without

An ancient description of a wise man is that he is the same on the inside and the outside. That means that as he thinks, so he speaks and acts. There are other things that might be said of the wise, but this simple description comes to us now as the essence of the modern term “transparency”.

It means that there should be no disjunction, no blemish in concept or communication and nothing obscured when it comes to public decisions and action.

The leaked emails from the Climatic Research Unit (CRU) at the University of East Anglia involve just a small coterie of scientists. However, they have been at the centre of climate science for a long time and their views, aspirations and activities have had effects far beyond their immediate working environments.

Salinger’s adjusted data now online

By courtesy of Mr Warwick Hughes, who kindly sent it to us, we are pleased to post this spreadsheet containing the historical New Zealand temperature series. The data are from the seven weather stations chosen by Dr Salinger and adjusted by him to represent the country’s temperatures, although it does not include the actual adjustments made or the reasons for them.

When plotted, it produces a graph similar to the one on NIWA’s web site that shows strong warming during the 20th century.

Wratt’s prediction falsified already — by his own graph

A funny thing happened last week involving Parliament but almost nobody noticed. Without my observant scientist friend, I wouldn’t know about it. We’re all pretty lucky that he put two and two together, but that’s what scientists are good at. He tells me they practise putting them together three or four times a week and some of them are so good at it they have trouble getting them apart.

So what happened? First, our study appeared, with a copy of the official NZ graph showing strong warming over the last hundred years. Second, Nick Smith said NIWA tells him New Zealand’s global warming will be much milder than elsewhere. Can both statements be true? Only if our steep temperature rise suddenly slows right down! It’s another mystery. Continue Reading →

Supplementary Information – Hokitika

Are we feeling warmer yet?

NZ Climate Science Coalition & Climate Conversation Group
30 Nov 2009

A number of people have now asked us for the raw data we used to create the unadjusted versus adjusted temperature graphs in our study Are we feeling warmer yet? We will shortly post a list of station names from the NIWA CliFlo database. While we could post the data directly, it would be fairly pointless, as you would need to know in detail the weather stations and the methods we used to combine them. Each station required some experimentation and detective work, assumptions had to be made and we may well have made errors. We make no claim to be infallible, so we publish these notes to let the reader judge whether our study has merit.

We will shortly be making the Salinger adjusted dataset available. We would like to thank Warwick Hughes for providing us with that data.

In this document we want to work through an example weather station—Hokitika—to illustrate our approach and methods. We also want to address NIWA’s response, currently on their website, that the Wellington adjustments are justified by altitude differences between stations where no time series overlap is available (Thorndon, Kelburn and Airport). The assumption is made by NIWA that stations can be adjusted together in such cases (even though they have no common overlap period and are also separated both spatially and temporally) as long as they share a common height above sea level.

By giving examples of stations with both altitude separation and an overlap period, we show that the lapse rate can differ and even the sign of the temperature difference can be reversed. Some higher stations record warmer temperatures than nearby lower stations. Therefore, it is invalid to move two station records together simply because they share a station height.

Notes on replication — station data

Are we feeling warmer yet?

NZ Climate Science Coalition & Climate Conversation Group
29 Nov 2009

We’ve heard from a number of people wanting to replicate the graphs. However, we never expected such a high level of interest in our study so we were somewhat unprepared. We are now putting together a posting that will specify stations and describe our methods which we hope to post in the next few hours. In the meantime, this note outlines the difficulties. It doesn’t answer your needs, and for that we apologise, but we’re working on something more substantial right now. Continue Reading →

Are we feeling warmer yet?

The New Zealand
Climate Science Coalition
25 November 2009

(A paper collated by Richard Treadgold, of the Climate Conversation Group, from a combined research project undertaken by members of the Climate Conversation Group and the New Zealand Climate Science Coalition)

There have been strident claims that New Zealand is warming. The Inter-governmental Panel on Climate Change (IPCC), among other organisations and scientists, allege that, along with the rest of the world, we have been heating up for over 100 years.

But now, a simple check of publicly-available information proves these claims wrong. In fact, New Zealand’s temperature has been remarkably stable for a century and a half. So what’s going on?

New Zealand’s National Institute of Water & Atmospheric Research (NIWA) is responsible for New Zealand’s National Climate Database. This database, available online, holds all New Zealand’s climate data, including temperature readings, since the 1850s. Anybody can go and get the data for free. That’s what we did, and we made our own graph.
