NZ warming ‘transformation’ wrong

The Herald’s false headline, decorated by a bushfire. But the weather does not light fires. Fires are caused by arson and lightning.

The NZ Herald reports on a new paper that claims to see a “growing hand-print of climate change” on the New Zealand climate since 1871, calling it a “150-year climate transformation.”

However, doubts have been raised. The paper claims our “wider region” has warmed by 0.66 °C from 1871 to 2019. But that is wrong, because records from 1850 show they recorded exactly the same temperatures as today: the country has NOT warmed.

The records are in Transactions and Proceedings of the Royal Society of New Zealand of 1868, held in the National Library in Wellington (image below, right). Today’s temperatures are the same as they were in the 1850s and ’60s.

This Claytons global warming

The global warming you have when you have no global warming

“The drink you have when you’re not having a drink”

Like the sham whisky peddled in the 1970s and 80s, today’s fashionable narrative of global warming satisfies no one.

Climate realists and sceptics, knowing the facts, are frustrated by witless political surrender to counterfeit science, while climate agitators declare a crisis just to make something happen, since there’s no public belief, no political commitment and—fundamentally disturbing—no warming.

Yes, we have not been warming (well, nothing you could call a crisis …).

Unscientific views of scientist Salinger

Herald headline, 4 August – Climate scientist: It’s cold now, but NZ region just saw its warmest July.

Image result for Jim Salinger climate

Prof Jim Salinger

Professor Jim Salinger, who helped create the benchmark seven-station national temperature series, the 7SS (or SSS, if you prefer), now runs a competing series using 22 hand-picked land weather stations (let’s call it the 22-station Salinger series, or 22SS). He claims July is an all-time record 1.79 °C above average, while the previous record of 1.74 °C above average in July, 1998, is demoted to second. Continue Reading →

The activists are hotting up

Here’s a piece, including graph, regarding Jim Salinger’s opinions on global warming that I thought the NZ Herald might like for an op-ed three weeks ago. They didn’t. It’s now slightly improved and I’ve added the earliest NZ temperature records. I like the fact that the error margins swallow these Lilliputian record margins. — Richard Treadgold

A week ago, Dr Jim Salinger, jumping the gun a little, predicted 2018 would prove to be NZ’s hottest year. The Herald indulged his forecast (inadvertently awarding him the title professor) with the heading 2018 NZ’s hottest year on record. Unfortunately, when they published NIWA’s official data a few days later, Jim’s claim turned out to be wrong, with 2018 declared the second-hottest year, following 2016. Continue Reading →

Response to NIWA comment on de Freitas reanalysis of the NZ temperature record

• Guest post •

— by Barry Brill, Chairman of the New Zealand Climate Science Coalition

This note offers brief replies to specific aspects of a Comment by NIWA scientists (called hereafter “NIWA Comment”), published in Environmental Modeling & Assessment in April, 2018, concerning A Reanalysis of Long-Term Surface Air Temperature Trends in New Zealand (by de Freitas et al., 2015) (“de Freitas”).

  1. Abstract

Since there was a systematic tendency for the seven-station sites to be relocated to colder locations as the early half of the twentieth century progressed, [de Freitas’s alleged] rejection of valid adjustments produces an artificially low rate of warming.

Climate bombshell — NZ has not warmed for 19 years

The data say one thing

[CORRECTION 1 Nov 2017 1945 NZDT: The original post used annual data. Figures for the standard error at 19 and 20 years have been removed until I can redo them using monthly data. The trends are unaffected. RT]

[CORRECTION 2 Nov 2017 1605 NZDT: There have been numerous changes to align this post with a Coalition submission to the Royal Society. There are minor changes, references to error margins and to the 20-year chart have been binned and the title changed to “… not warmed for 19 years”. RT]

For the national temperature record, the 7SS, NIWA have collected the data, checked it, adjusted it, approved it and published it on their website, so they can scarcely now argue with it. But, on the other hand, it’s totally at odds with what they say in public. Note to MSM: this ought to be front-page news.

NIWA scientists agree de Freitas climate paper streets ahead?

It’s six years since NIWA published their Report on the Review of NIWA’s ‘Seven-Station’ Temperature Series (pdf, 8.5 MB), the latest version of the national temperature record. It’s six years, too, since NIWA promised the people of New Zealand (in Parliament) they would publish the methodology in that report in a peer-reviewed journal. But they haven’t done so—maybe they aren’t too pleased with it.

Last year, three scientists associated with the NZ Climate Science Coalition published a peer-reviewed paper concluding the New Zealand temperature rise over the last hundred years was only 0.28°C, much lower than the last NIWA effort, which claimed it was 0.91°C. Though I notice just now when checking the NIWA website they’re claiming 0.92°C.

Point 1

When he says:

Let me pose a question. What does Dedekind think Rhoades and Salinger were doing in their 1993 paper? Indulging in a purely theoretical exercise? In fact, they developed their techniques by working on what became the Seven Station Series (7SS), and from 1992 onwards the 7SS was compiled using RS93 methods properly applied.

We’ll call that Debating point 1. From 1992 onwards the 7SS was recalculated using the Rhoades & Salinger (1993) measurement techniques.

Egos of NIWA

John Morgan, the Chief Executive Officer of NIWA, perhaps the country’s premier scientific institute, has misled the press and the people of New Zealand. He made a public claim of international recognition of NIWA’s temperature adjustment methods but refuses to provide evidence of that recognition. How can anyone believe him?

After NIWA published a review of the national temperature record (called “the Review”) in December 2010, the NZ Climate Science Coalition asked them how they adjusted the temperatures. What method did they use? It’s a reasonable question. If you knew that, you could try to replicate NIWA’s results. Replication is what science is all about. Continue Reading →

NZCSET – mischievous or sensible?

The NZ Climate Science Coalition’s opponents have attacked it for creating a Trust (the NZ Climate Science Education Trust, NZCSET) for the sole purpose of unfairly (perhaps, in the opinion of some, unlawfully) avoiding costs if they lost the court case against NIWA.

However, there are sensible reasons for creating a legal entity to take someone to court. One of the first questions a judge asks is “who are the parties?” If that simple question cannot be answered by naming a legal entity the case doesn’t get off the ground and the judge just gets annoyed.

So, although the NZCSC did the scientific work in challenging NIWA’s techniques, it couldn’t take the court proceedings. An unincorporated association cannot sue or be sued, as it has no legal existence separate from its multifarious members. Continue Reading →

Prolix redefined

To be a judge in New Zealand is to wield substantial power. Here we have evidence that judicial power can reverse the meaning of a word.

The judgement in our case against NIWA said at paragraph 9:

Both the original statement of claim and the first amended statement of claim were prolix.

The word “prolix” comes from the Latin “prolixus”, which means “extended” (literally “poured out”) or “courteous, favourable”. It has come to mean “tediously lengthy, bombastic, long-winded, verbose, wordy.”

Affidavit AWFWY wrong

In November 2009, about a week before the international climate change conference in Copenhagen, the CCG and the NZCSC (the Coalition) released a paper we’d been working on for some time — “Are we feeling warmer yet?” (AWFWY).

On pages 13 and 14 of his affidavit to the High Court, Dr Wratt devotes six paragraphs to our paper and contrives to misrepresent it – obviously trying to give it a bad name. First, he correctly quotes a sentence from the paper:

There are no reasons for any large corrections.

Then he observes:

“NZCSC members… appear to ignore the fact that good scientific practice requires adjustment for site changes before temperature series are analysed for long-term changes.”

Thus he establishes two things:

1. The paper finds no reasons to make large corrections, but it should.
2. The paper makes no corrections, but it should.

The New Zealand Climate Science Education Trust (NZCSET) contested the claim by the National Institute of Water and Atmospheric Research (Niwa) that New Zealand air temperatures had climbed by 0.9°C over the past century.

Quo vadis?

It was a great disappointment that Justice Venning was not prepared to declare NIWA’s data adjustments to be a breach of the Crown Research Institutes Act 1992.

On the law, the Judge found that any review should be “tolerant” and “cautious” because NIWA was “a specialist body acting within its own sphere of expertise.” He declined to rule on the disputed science – while tending to favour the 92-page opinion evidence provided by NIWA’s Dr Wratt (which was not subject to cross-examination).
