New Aussie state of the climate snapshot: NZ needs one too

Australia’s CSIRO and Bureau of Meteorology have released a State of the Climate report [PDF], a succinct six page effort designed to provide the Aussie public with an overview of how their climate has been changing, and how it is expected to change in the future. Headlines (from the media release):

  • Highly variable rainfall across the country, with substantial increases in rainfall in northern and central parts of Australia, as well as significant decreases across much of southern and eastern Australia.
  • Rapidly rising sea levels from 1993 to 2009, with levels around Australia rising, between 1.5cm and 3cm per decade in Australia’s south and east and between 7cm and 9cm in the country’s north
  • About half of the observed reduction in winter rainfall in south-west Western Australia can be explained by higher greenhouse gas levels.

The news about temperature isn’t good either. All of the continent has warmed over the last 50 years, but some regions have warmed at up to 0.4ºC per decade during that time (see the dark red blobs on the map above) and have seen warming of 1.5 — 2ºC. By 2030 the average temperature is expected to have increased by a further 0.6 — 1.5ºC, and decreases in rainfall will continue in the south, south-east and southwest. The graphics are particularly good — and very telling.

I’m not aware of any similar recent overview for New Zealand, and with the usual suspects doing their level best to promote uncertainty and inaction at the moment, it would be helpful if the local climate science community could cooperate on producing such a clear statement of current evidence and future change. NIWA’s last set of projections for NZ were released in 2008, and are summarised on this informative but rather dense web page. I had a go at bringing the details to a wider public, via articles in NZ Geographic (not my knees, by the way) and Good magazine, but apart from press coverage when the projections were launched, there’s not been much since. I doubt many people will seek out Climate Change Effects and Impacts Assessment: A Guidance Manual for Local Government in New Zealand, 2nd Edition (Ministry for the Environment 2008) for an easy introduction to the subject…

Sorry seems to be the hardest word

homer.jpgLate last week Richard Treadgold, author and principal promoter of the recent attempt to cast doubt on the long term temperature record for New Zealand, popped up on Hot Topic to leave one of his typically rambling and pompous comments. Regular readers may recall that following the publication of his Climate Conversation Group/Climate “Science” Coalition “paper” last year, I told Treadgold (after a similar long comment) that he was no longer welcomeat Hot Topic:

Until you are prepared to withdraw and apologise for the incompetent analysis you released, and specifically apologise to the scientists whose good name you have felt free to smear, I will be forced to conclude that you remain a liar and a charlatan.

Until such an apology and withdrawal is made you are not welcome here.

His report has not been withdrawn, and no apology has been forthcoming. He therefore remains unwelcome here. I reminded him of this in an edit to his comment last week (the first he’s made since December), and deleted two subsequent attempted comments.

If you’re going to join the conversation at Hot Topic, you have to play by the house rules. Some of them are reasonably flexible — I like people to be polite, but I’m not too fussed if the language or argument are robust — but there is one thing that I don’t tolerate, and that is the casual smearing of working scientists, most of whom are in no position to defend themselves. Reputations are hard won things, and can be lost in a flash. Playing vicious politics with people’s careers is the worst aspect of the current campaign to delay action on climate change, and it’s a tactic Treadgold seems to have adopted with relish. Let’s look again at the CSC/CCG report Are we feeling warmer yet? and review some of his recent blog posts.

 

In a post titled Apologise? Why? back in February, Treadgold appeared to have forgotten my earlier remarks, and asserted that “there’s no reason for us to apologise”. Following my deletion of his comments last week, he posted this:

From the response, you’d think we’d committed a crime. The only crime I can identify is a certain bunch of public so-called “servants” in charge of NIWA engaging in pervasive obstruction and citing references to us and the New Zealand public which proved to be entirely empty. They said the material we sought was there and it was not there.

One day soon they must account for that. They must also account for misleading their minister in guiding him to false replies to the Parliament.

Note the language and the allegations, which border on the defamatory. A couple of days later, he attempted a tactical revision of history in this post, claiming that his paper had been misinterpreted:

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.

What does the paper actually say?

  • …the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming
  • We have discovered that the warming in New Zealand over the past 156 years was indeed man-made, but it had nothing to do with emissions of CO2 — it was created by man-made adjustments of the temperature. It’s a disgrace.
  • Using NIWA’s public data, we have shown that global warming has not yet reached New Zealand (and what does that say for global warming?).

[My emphasis]

No misinterpretation at all. The paper was designed to make the public and the world believe that there were “problems” with the NZ temperature record, that there was no real warming. The press release that accompanied the paper was quite clear about it. Here’s the headline and opening sentence:

NZ climate scandal: NIWA “adjusts” records to show warming

New Zealand may have its own “Climategate”, including manipulation of temperature readings […] researchers claim that temperature readings from seven weather stations throughout New Zealand have been adjusted to show a higher degree of warming than is justified by a study of the original raw data.

And what was that about not supporting “no warming”? Here’s the press release again:

Spokesman for the group, Richard Treadgold, said that recent claims that New Zealand is warming have been proved wrong. “Official information clearly shows that temperatures in New Zealand have actually been remarkably stable since 1850.”

And here’s the attempt to smear Jim Salinger…

“NIWA’s official graph (done originally by Dr Jim Salinger, who features also in the emails leaked from the Climatic Research Unit of the University of East Anglia) shows considerable warming, which they give as 0.92°C per century, saying this is consistent with global warming over the 20th century. But the actual temperature readings taken from the thermometers show an almost flat trend for 150 years.

Back to Treadgold’s attempt to rewrite history. Later in that post he dismisses calls for an apology:

Those apologists for NIWA who complain about our paper smearing the reputations of their scientists should reflect on this: that these changes were made in secret, are still, today, undisclosed (Hokitika has apparently been fully described, but we have not finished checking it) and, by NIWA’s own admission, these changes introduce warming to raw data that show no warming and NIWA have refused requests for them from bona fide scientists for decades.

That really is a disgrace.

The disgrace is Treadgold’s. Adjustments were never made in secret, the raw data is available, and the techniques used to combine station records are well-established in the literature and in the public domain. NIWA last communicated with the Climate Science Coalition on the subject of the adjustments made when homogenising station records in 2006, when Jim Salinger exchanged emails with Vincent Gray. Gray reviewed the CSC/CCG paper before release, according to Open Parachute blogger Ken Perrott, who has been diligently attempting to hold Treadgold to account in comments at his site. Here’s Treadgold, prompted by Perrott, talking about Gray’s review:

Please don’t use Dr Gray’s comment allegedly admitting a mistake. He was being his normal conservative self and I disagree with him. He, being a scientist, found it hard at first to grasp the essentially political objectives of our paper and looked at it from the normal scientific point of view. So he was of the view that we should be describing error limits, doing statistical analyses and quoting learned papers.

Those techniques were no help to us – they weren’t even necessary. We set out simply to motivate scientists to talk to us for the first time in 30 years.

Revealing, eh? The paper is admitted to be “essentially political”, so normal rules don’t apply. Let’s ignore the science, let’s not do the hard yards to understand the subject, let’s just fling mud. And then expect the scientists to cooperate…

This whole affair has never been anything other than a thinly disguised propaganda exercise, designed to capitalise on the noise about stolen CRU emails toplay politics in New Zealand. That it has been jumped on by parliamentary sceptics like Rodney Hide and John Boscawen is perhaps not surprising, given the fawning treatment of ACT and its luminaries by Treadgold. Here’s an exchange in comments at Treadgold’s blog this morning, apparently between Hide and Treadgold:

Hide: And on the basis of these numbers, and this advice, the government has committed to an ETS that will cost NZ conservatively a billion dollars a year.

We need to hold NIWA to account. Good work!

Treadgold: Yes, one’s tempted to call it shonky, but it isn’t. The ghastly thing is that AGW was created and the ETS introduced in the full light of consciousness to achieve ideological objectives.

We’re fortunate to have in high places men like you with the courage to speak the truth and to question error.

Thanks, Rodney.

Hide’s comment (if it really was Hide) is remarkable. Neither this government or the last committed to an ETS solely on the basis of NIWA’s New Zealand temperature record. The NZ numbers are just one tiny part of an immense jigsaw of evidence handily summarised by the IPCC, and accepted by every government involved in the IPCC process. Even if New Zealand were cooling, it would have no discernible impact on the global picture, either on the need for emissions reductions or for policy to encourage those reductions. The NZ temperature record is interesting — fascinating, even — but it is not crucial to anything, let alone national or international climate science or policy. And that fact, perhaps more than anything else, is what shows Treadgold to be little more than a tawdry propagandist for inaction.

Meanwhile, the taxpayers of New Zealand might want to know how much of NIWA’s time has been wasted dealing with frivolous freedom of information requests and ACT questions in Parliament. NIWA time is public money, and Treadgold and his courageous friend Rodney are wasting buckets of it. Perhaps there might be scope for a question in Parliament…?

Finally, unless and until Treadgold withdraws his paper, apologises for the attempt to mislead the public, and for the direct smears on Salinger and the scientists working at NIWA, he will take no further part in the climate conversation at Hot Topic.

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.

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.

Craziness in Copenhagen

coplogoOur second guest blog from a member of the NZ Youth Delegation comes from Louis Chambers — a 20-year-old student studying in Otago. He grew up on a farm in Hawke’s Bay, where he developed a passion about the outdoors. With the rest of the twelve young New Zealanders in Copenhagen, he’s doing his best to ensure that the youth perspective is heard at this critical time.

It is impossible to capture the diversity of the Copenhagen negotiations in one article. There is a city packed full of climate change seminars, events and displays. There are hundreds of businesses, NGO’s and universities offering regular talks and lectures. Even if you make it to the negotiations, they are so formal and detached that the human lives behind climate change are forgotten. The challenge is to stay focussed in the face of masses of information, numerous distractions and a negotiating process which reduces a critical moral issue down to numbers and data.

The first thing to realise is that the term “Copenhagen negotiations” is misleading. There is so much more going on other than just negotiations. For example, there have been incredible speeches from the likes of Desmond Tutu and Bill McKibben (the founder of 350). Unfortunately I did not see either of these speakers: I was too busy at the host of other events available. There are events looking at climate change in almost every context, from human rights to business, local government to youth.

If these events and speakers do not capture your imagination, then the negotiations themselves should. The negotiations bring together 192 countries from every corner of the world. When I first sat in the “plenary session”, the sheer number of countries blew my mind. The discussions took me on a tour of the globe as my geography was tested by the numerous countries awaiting their turn to speak.

However, in the excitement of the negotiations, I realised that what is important is to keep focussed on the reality of climate change. That reality is that behind all awe and the fun, all the men in suits, there are human lives being negotiated. As the International Youth Climate Movement often says: “Survival is not negotiable”. This realisation symbolises a process which occurs here. We are blown away by the information, the glamour and the opportunity. Yet in the same instant we realise that the magnitude of the challenge faced is incredible.

People power can still drive political change here in Copenhagen
The difficulty I have had in these negotiations is that Governments themselves lose this perspective. They become lost in all the numbers and the data. They also become lost in the world of politics. As different countries try to “win” the political game, they forget why we are all here.

Why are we all here? As young people, we have been able to remind Governments that we are here to negotiate our future. Behind all the numbers and all the politics is a stark choice. If we cannot keep global warming below 2 degrees, we are effectively choosing to erase any hope of a safe, not to say prosperous, future.

Of course, even simple goals like keeping warming below 2 degrees are not easy. In order to reach this goal, you do need the economic models and the complex data. You do need politicians who can negotiate.

The problem is that so far in these negotiations politicians seem to have become so immersed in how to reach the goal that they have forgotten why the goal itself is so important. As the New Zealand Youth Delegation, we have been working hard to keep the importance of the goal fresh in their minds. As we run out of time to reach an agreement, you can do this too.

Send a love letter to John Key at www.dearjohn.co.nz. We are currently delivering letters from this site in person to John Key. Or join 12.5 million other people from around the world in calling for a fair, ambitious and binding agreement here in Copenhagen – click here.

After all, we are the ones who give leaders the power to lead. Currently, the draft text is confused and complicated. It is no surprise given the complexity of issues here in Copenhagen. However, Kyoto was negotiated at the last minute. With over 110 leaders here in Copenhagen now, we certainly have enough political will to produce the result the world wants and which our future generations need.
