Climate Conversation Group

A survey begins

When we published our paper Are we feeling warmer yet? last November, criticising the Seven-station Series (SS), NIWA quickly produced what they call the “Eleven-station Series” (ES) to counter it. They went to the trouble of asking Dr Jim Salinger, recently dismissed and author of the original national temperature series, to help them create it, which makes us realise that nobody at NIWA understands how he produced the original figures.

According to the NZ Herald, Jim specially selected the stations for the ES.

Some people would be impressed by that news, but others find their antennae stiffening at the idea of “specially selecting” data for any reason. It might be justified, but then again, it might not. The situation calls for careful study. So what has happened? We can say a few things about it.

Scientists in the Coalition have had a look at the new series and found problems with it. Read more… »

Dr James Hansen, former respected space scientist, “father” of global warming, now an unrepentant activist warning of nothing less than the imminent destruction of the world — which at one time was the very definition of ‘crank’.

While on the subject of awkward, unanswered emails, let me pass on a message I recently sent to Dr James Hansen, the scientist widely famed as the “father” of global warming. I still hope he will offer some explanation.

4 March 2010

Dear Dr Hansen,

The Climate Conversation Group and I have become interested in the very meaning of “taking the temperature”, calculating the so-called “average” temperature for a place and a region and the meaning of doing so. I have just seen your web page [The Elusive Absolute Surface Air Temperature (SAT)], discussing these and related matters. It is an interesting and informative page.

You say there is no agreed method of measuring surface air temperatures and, in fact, there are numerous practical and theoretical obstacles to ever achieving such a measurement.

There is a very obvious question raised by that discussion. We are interested to know why, if it cannot be done, do you do it?

Regards,

Richard Treadgold
Convenor

The Mobius strip, invented in 1865 by German mathematician August Ferdinand Möbius. It has the unique and apparently inexplicable property of having just one side and one edge. This makes for longer-lasting conveyor belts and endless fun for mathematicians. It’s also a good metaphor for the struggle to know what REALLY happened with the history of NZ temperatures — have they gone up or down? It seems they’ve gone all around the houses and ended up just where they were 138 years ago. Who’d have thought?

Most people take for granted that New Zealand’s surface air temperatures (SAT) have gone up over the last century. But is that true?

NIWA’s official graph of the national temperatures is well known. You can get it from their web site. By the way, if you go there, let me know if you think they’ve recently stretched the image laterally; it is definitely wider than before — even the text is obviously stretched sideways. Could they be trying to make the vertical change less prominent and thus reduce the apparent slope of the trend line? What goes through their minds at NIWA? Anyway, as copied a few months ago, and so a little different, it looks like this:

NIWA’s official NZ temperature graph. The straight line is the linear trend over 100 years, showing we’ve warmed by about 1 degree Celsius between 1905 and 2005. Click for a larger version.

You should be aware that the Climate Conversation Group and the NZCSC have delivered a rip-snorting criticism of this graph, so we don’t agree with it even for a moment. Now I will raise further objections to NIWA’s graph because it contains features inconsistent even with NIWA’s own conclusions. Read more… »

A snow-covered Stevenson screen — which seems to put global warming into perspective. This standard enclosure for weather recording instruments, such as thermometers, hygrometers, psychrometers and barometers, was invented in 1818 by a British engineer. It keeps the instruments dry and shades them from direct rays of the sun while allowing the air to circulate freely. For more on Stevenson screens, weather stations and generally measuring temperatures, visit Watts Up With That (perhaps our favourite climate site).

NIWA keep talking about various reasons to adjust the official New Zealand temperature readings. They say one must account for changes in location, exposure, urbanisation and instrumentation. For some reason they continually harp on about the altitude difference between Thorndon and Kelburn (Wellington).

But it is empty talk, because they have never made changes for those reasons. Are you listening? People of New Zealand: scientists from the National Institute of Water and Atmospheric Research (NIWA), your country’s publicly-funded, premier environmental research organisation, have lied to you and continue to lie to you.

The surface of the Sun, which is hotter than you can imagine. It is hotter even than a sausage being fried to the edge of its existence in a hot frying pan, so it is very hot indeed. A picture of the sun’s surface is often used like this to illustrate a story involving heat, but when the amount of heat involved in the story is vastly different from the amount pictured, it’s a deceptive trick. This is a trick.

John Key: you must bring NIWA to heel

The Waikato Times yesterday wrote:

Niwa principal climate scientist Dr Brett Mullan said Niwa “had the original data, knew the method of the calculations, and we have the answers”. There was “no scientific issue from our perspective”, and Dr Salinger’s work had stood the test of time.

So what are the adjustments

The NZ Climate Science Coalition began asking NIWA for the adjustments to the national temperature record in late November.

NIWA have told us where we could find the adjustments; we searched for them where they told us to search; the adjustments are not there.

NIWA have said: “We have the methodology, it’s in a student’s thesis [and other sources] from 1981, just read it.” The Coalition never asked for the methodology, we asked for the adjustments, but we looked anyway. Read more… »

The official New Zealand temperature graph from NIWA. Their web site claims “a warming trend of 0.9°C over the past 100 years (1909 to 2008)”. But the period since about 1950 (highlighted) is virtually free of warming, verified by senior scientist Jim Salinger (ex-NIWA employee) as having a warming trend of 0.3°C. Click for larger version.

What’s going on?

NIWA goes to a lot of trouble to warn us about the coming “climate change” causing warming between 0.7°C and 5.1°C by 2090. But I can reveal evidence that our top climate scientists don’t believe this.

Should New Zealanders expect significant warming for the next 80 years? You might be surprised to learn — especially if you’re following the discussions here — that scientists with NIWA, whose job is to research the climate, tell us we already haven’t had any warming to speak of for about 60 years and we won’t get serious warming in the future.

Now that’s not the message we normally get from government scientists! Read more… »

NIWA’s raw data from each site in graphical format, showing when each adjustment was made and its magnitude. These are the facts at the heart of our paper, no matter that our critics can talk only of the opinions it expresses. Instead, they should address their attention to these facts and recognise that NIWA refused, without reason, to release the adjustment details, giving us false references that sent us on a wild-goose chase. Then they ought to ask why NIWA did this.

The paper we published last November continues to attract attention. The sceptics like it since it seems to refute any warming in New Zealand and the warmists like it since it seems to present a loutish, unscientific punching bag.

The truth lies more moderately somewhere in between.

The sceptics shouldn’t look to our paper to refute local warming, because it doesn’t. It presents no evidence on the quality of the national temperature graph — it merely questions the data, expresses strong doubts about their accuracy and wonders what adjustments were made to them.

Salinger contradicts Wratt in writing

Those looking for a refutation of New Zealand warming actually need look no further than NIWA’s own graph of the New Zealand annual temperature series, which shows no significant warming since about 1950. Here’s a copy:

NIWA’s graph of the NZ annual temperature series.

In confirmation of this, Dr Jim Salinger expressly claims that the NZ temperature increase over the last 50 years is only 0.3°C. In an email to Vincent Gray in 2006 he said:

A linear trend fitted to the data over the period 1950 – 2005 is equivalent to an increase of 0.4°C over that period (or 0.3°C fitting a trend to the last 50 years, 1955 – 2005).

That’s a far cry from 0.92°C over the last 100 years, which is what David Wratt last claimed. The first 50 years must have been scorching! Read more… »

Good grief!

I’ve just come across this video of Godfrey Bloom, Member of the European Parliament for Yorkshire. He was speaking in Strasbourg during the debate on the outcome of the Copenhagen summit on climate change when he gave this furious tirade against the belief in global warming.

The surprise for us was that, near the end, announcing that the New Zealand temperature database was “fraudulent”, he suddenly brandishes a copy of our report, Are we feeling warmer yet? It’s a dramatic moment!

So how about that, then?

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… »

The Wellington offices of NIWA. Yes, the anonymous building in front dominates the image. No, I don’t know whether it belongs to NIWA.

NIWA blundered in not keeping track of some important records that justify the country’s warming since the 19th Century, even if it inherited the problem from its predecessor in the Met Service, or the early behaviour of Jim Salinger, who did the work. It blundered again when, instead of being honest, it attacked the CCG and the NZCSC when we asked to know the Schedule of Adjustments.

Now NIWA has admitted in writing that it lost the original data. This settles our original question for the moment and sets them free to go about repairing the situation. Their general counsel, Tim Mahood, made the admission a few days ago, and here’s the letter to prove it.

The NZ Climate Science Coalition had asked NIWA under the Official Information Act last December for the details of the adjustments. This is the original request.

Finally, here’s the hard-hitting letter the Coalition sent back to Mr Mahood, setting out the defects in his official OIA response the day before. Have a look at it — it’s dynamite.

Now we’re waiting for them to finish re-creating the adjustments to the NZ temperature record and to post them on their web site. They told us today it should happen this month. We’re on tenterhooks and can’t wait to have a look at it.

A month ago, when Hot Topic was berating us as unscientific and demolishing our case against NIWA, how many people thought our request was unjustified? How many thought NIWA could do no wrong? How many will apologise to us? Yet who has proved truly scientific? Who has helped to actually improve New Zealand’s temperature record?

For that will be the long-term result of our efforts. What a wonderful thing!

Having (no doubt painfully) admitted to losing Salinger’s working documents, NIWA is now free to pick up what old records it has and work on them afresh. Without the confession the old records must have languished untouched, their taudry reputation defended less and less vigorously by an organisation tarnished by its neglect of verity. A new spirit of honesty will invigorate the place, for truth sets everybody free. The result must be a more accurate dataset and more confident predictions for the future.

I wonder what Hot Topic makes of that?

Richard Treadgold, joint CCG – NZCSC project spokesman

NIWA have published misleading material on their web site and seem to have advised the Minister for Climate Change Issues to give evasive answers to questions in the Parliament.

For those unfamiliar with the story: NIWA keeps raw data for the national NZ temperature record and makes it available on their web site. The Climate Conversation Group and the NZ Climate Science Coalition conducted a joint study of the temperature record, researched by a science team and published on 25 November under the title Are we feeling warmer yet?.

But we’re only asking about the weather

That study demonstrated that the official graph does not represent the raw temperature data. NIWA told us that adjustments have been applied so we’ve asked for the details. So far they obfuscate. We don’t know why they refuse to disclose what the weather has been.

We conclude that NIWA’s response to our enquiries has been defensive, obstructive and oddly disparaging.

The Hon Rodney Hide became concerned about deteriorating standards in public science and asked in the Parliament whether the Hon Dr Nick Smith would require NIWA to release the full data for the official NZ temperature record. On the last possible day for answering, Nick finally replied: “You must ask Wayne Mapp; he’s the responsible minister (for Research, Science and Technology, the portfolio that covers NIWA).” We won’t get any Parliamentary questions answered now until well into the New Year, so Nick Smith has caused a considerable delay in getting this information to the public.

Gratuitously, he added: “I would note however that the NZCSC have had this information since 2003.” He hoped that little factoid would hurt the Coalition’s reputation, but it won’t, although it might hurt his own — because the Coalition didn’t exist until 2006.

See the email, they said, but they deceive us

NIWA say that the Coalition have had all the information needed to reproduce the official graph since 19 July, 2006, when, they say, “NIWA advised NZ Climate Science Coalition member Dr Vincent Gray” of the need for adjustments and gave him a couple of examples. Dr Gray has located an email of that date and we can now reveal that it was from Dr Jim Salinger, not NIWA, it was not addressed to the Coalition and did not mention the Coalition.

It was sent just a few weeks after the Coalition was created, before they ever discussed the national temperature record. Dr Gray tells us that and other emails before and since were not official communications on either side — they were letters between two scientists who had known each other for years.

But most significantly the email does not give details of the adjustments made to the temperatures, nor does it give the information required to derive the adjustments. Dr Salinger just discusses the changes in a general way and gives a few examples and that’s all. NIWA’s assertion that that email contains the requested information is not supported by reading the email. Read more… »

Steve O’connor is a senior geologist who has studied paleoclimate for 40 years. He lives in the circulation area of the Taranaki Daily News, which today published some astonishing comments from one Trotter. I am, unfortunately, unable yet to confirm the Taranaki Daily News item or give a link to it, but I am re-publishing Steve’s letter anyway, because it is the best summary I have read of the central anxieties arising from the global warming scam.

UPDATE 14 Dec 8:30 am: To give you just an outline of Trotter’s complete abandonment of evidence-based science, his denial of the right to free speech and his denial of evidence-based doubts of man-made global warming, here are the concluding comments from his Dominion article, titled “In the war for nature, the deniers are traitors”:
“There will, of course, be people who whisper that the enemy isn’t really our enemy … In 1940, England was full of such whisperers. The British ruling class, in particular, was riddled with defeatists, Nazi sympathisers and traitors. Back then people called them “Quislings” and “Fifth Columnists”. If, therefore, the battle against climate change has to become the moral equivalent of war, with all the sacrifice that war entails, then climate change denial must become the moral equivalent of treason. Over the top? No. The stakes really are that high.”

It is sobering to reflect that, a mere 65 years after World War II, which killed so many of our finest young men as they defended the freedom we still live in against the oppression from without of the advancing fascist barbarians, we are about to subjugate ourselves from within. For the remaining vestiges of that freedom are about to be crumpled in the unelected fists of the most devoted, socialist, totalitarian, “environmentalist” bureaucrats the world has ever produced, justified solely on the grounds of non-existent evidence of man-made climate control.

A menacing interpretation

When I first encountered, a couple of years ago, this menacing interpretation of the approaching “carbon crisis” I scoffed. It was alarmist nonsense; outlandish that anybody would do such a thing; an imaginary conspiracy from the paranoid—surely the movement is based on the science of the enhanced greenhouse effect?
