La-la Land again: Jim Hopkins gets it wrong

It must be sceptic idiot week at the Herald. Not content with allowing Garth George to make stuff up, today they unleash that mighty wit (or should that be twit?) Jim Hopkins, who has been reading the Daily Mail‘s daft coverage of a BBC interview with Phil Jones, the man at the centre of the beat-up over stolen emails:

Professor Jones discussed many things with the BBC, including the trouble he has “keeping track” of information, but the professorial concession the Daily Mail pounced upon – and our media ignored – was this: He said that for the past 15 years there has been “no statistically significant” warming. “No statistically significant warming”. None. It’s not happening. Since 1995, we ain’t got hotter. And that’s not the sceptics speaking. That’s from a man who garnered $22 million to prove we were getting warmer. Much warmer, worryingly warmer, “Lucy Lawless was right” warmer. But now he says we’re not. And haven’t been for 15 years.

I suppose we can’t expect a newspaper columnist and professional funny man to understand statistical concepts. Jones did not say that there had been no warming for 15 years. He said that the warming trend over the last 15 years just fails to meet one test for statistical significance. Here’s Jones in full:

Do you agree that from 1995 to the present there has been no statistically-significant global warming?

Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level. The positive trend is quite close to the significance level. Achieving statistical significance in scientific terms is much more likely for longer periods, and much less likely for shorter periods. [My emphasis].

The Daily Mail misunderstood and/or misrepresented what Jones told the BBC — and that’s been extensively covered on the web. Hopkins is happy to repeat that misinformation without checking his facts. Perhaps he doesn’t understand how to use Google? More coverage of Mailgate at Deltoid, In It For The Gold, Real Climate, and for a full explanation of what statistical significance means in this context, Tamino has an excellent article here. Meanwhile, Jim should stick to his knitting instead of repeating tabloid lies from Britain.

Egg/face interface for Hide and the climate cranks

What was it Richard Treadgold and Rodney Hide were saying? Here’s Hide, speaking yesterday in Parliament:

So, before Christmas, I asked NIWA to disclose the adjustments and their reasons. They said they would. But they have just told the Climate Science Coalition they don’t have the record of the adjustments.

And here’s Treadgold and the NZ Climate Crank Coalition:

This follows an admission by NIWA that it no longer holds the records that would support its in-house manipulation of official temperature readings.

Just to to provide a little balance, here’s NIWA, yesterday:

NIWA has added two new documents to its National Climate Centre web pages to outline how and why it made adjustments to its 7-station temperature readings in order to provide accurate and meaningful data to use in a time series of temperature information.

One document [PDF] lists all the adjustments made to the station records used in NIWA’s long term New Zealand temperature series, while the second [PDF] looks at one station, Hokitika, and explains in detail the rationale for that station’s adjustments.

I look forward to the prompt release of apologies from Rodney Hide, Richard Treadgold, Terry Dunleavy and the NZ Climate “Science” Coalition to NIWA, Jim Salinger and all the scientists involved in preparing and maintaining NZ’s climate records, but I won’t be holding my breath.

The annotated Rodney Hide: treating parliament with contempt

rodenymorph.gifHow far can a Minister of the Crown go in misrepresenting the facts of a matter before he is guilty of misleading the House? That’s not an easy question to answer, but any sensible reading of Rodney Hide’s speech in response to prime minister John Key’s statement to the House yesterday would suggest that if there’s a line to cross, Hide’s not just trodden on the chalk but taken a flying leap into touch.

Hide is certainly parliament’s highest-profile climate “skeptic” (his spelling), with a long track record of spouting the standard climate crank arguments, but yesterday Hide combined a complete misrepresentation of the so-called “climategate” affair with a scurrilous attack on the National Institute of Water and Atmospheric Research, based entirely on the discredited smear campaign emanating from the NZ Climate “Science” Coalition and Richard Treadgold’s “Climate Conversation Group”. Here’s the relevant section of Hide’s diatribe, annotated by me to show just how far from the truth he strayed…

Treadgold and the NZ CSC: dogging a fled horse

The campaign by the NZ Climate “Science” Coalition and Richard Treadgold’s “Climate Conversation Group” to cast doubt on the NZ temperature record and to smear the scientists who have worked on it has stepped up a notch or two in recent days, following a response by NIWA to an Official Information Act request from NZ C”S”C secretary Terry Dunleavy. It seems Dunleavy and Treadgold didn’t like the answers they were given, because they immediately jumped on one small part of the response, and rushed out a press release throwing up their hands in in horror. Here’s Dunleavy:

The National Institute of Water and Atmospheric Research (NIWA) has been urged by the New Zealand Climate Science Coalition (NZCSC) to abandon all of its in-house adjustments to temperature records. This follows an admission by NIWA that it no longer holds the records that would support its in-house manipulation of official temperature readings. [my emphasis]

In December, NZCSC issued a formal request for the schedule of adjustments under the Official Information Act 1982, specifically seeking copies of “the original worksheets and/or computer records used for the calculations”. On 29 January, NIWA responded that they no longer held any internal records, and merely referred to the scientific literature.

“Merely” referred to the scientific literature? That’s where scientific knowledge is to be found, not in worksheets or computer records. Treadgold developed the theme at his blog, under the heading FARCE: NIWA don’t have the changes:

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.

Luckily for us, Treadgold later posted pdf copies of NIWA’s response, as well as Dunleavy’s original request, and so we can see for ourselves what NIWA said. Funnily enough, things are not quite as Dunleavy and Treadgold would wish us to believe.

Oops, he did it again

It pays to beware of leaving hostages to fortune: saying or doing something that might cause you some embarrassment in the future. There’s a very fine example in this recent blog post by Ian Wishart, titled “Top 10 global warming myths exposed“. It takes the form of a piece Wishart has submitted to the Coromandel Chronicle, taking exception to a column by Thomas Everth [PDF]. He begins:

In a blatant effort to mislead and scare your readers, Green blogger Thomas Everth makes more errors in the first 200 words of his recent global warming diatribe than I have made in my last three books totalling around 400,000 words.

As hostages go, that’s pretty impressive. Wishart proceeds to find fault with ten of Everth’s opening points, but does he make a few mistakes of his own in the process? I’m going to take a long, hard look: is that hostage feeling lucky?
