For all of its apparent complexity, the threat of dangerous anthropogenic global warming (DAGW) formulated at the Rio Earth Summit in 1992 is based on a very simple assumption:

When X = 560, Y = ECS

where

X = atmospheric concentration of CO2e in parts-per-million
Y = the increase in temperature since pre-1880, in °C
ECS (Equilibrium Climate Sensitivity) = 1°C plus the ultimate net effect of feedbacks

X is taken from the Mauna Loa observatory and Y is provided by five published temperature series, neither being deeply controversial. The sole debatable element is ECS, the assessment of which is described in Wikipedia: Read more… »

The planet is no longer warming. The brief warming episode of the late 20th century completed its course in the mid 1990s, and is now extinct. These are now uncontroversial statements. They are based on hard data which has been available for many years on the websites of many official agencies. But somehow those agencies found ways to interpret the data differently, and to continually sidestep the elephant in the room.

Just one day after the IPCC Chairman claimed that global warming had stopped happening 17 years ago, the Australian Climate Commission rushed out a press statement (February 23), “The Earth Continues to Warm.”

Clearly, there is a lack of consensus here. Are these diametrically-opposed views between leaders in the field of climate change? Not at all. On closer inspection, it all turns out to be that well-known sleight-of-hand which Americans call “bait and switch.” Read more… »

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).

Where does this now leave the NZCSC’s long-term effort to show that the NIWA temperature adjustments are wrong? Read more… »

NZCSC chairman Barry Brill has suggested to Environment Waikato that its Regional Policy Statement (RPS) should not be influenced by the climate change ‘Guidance Manuals’ (here and here) issued by the Ministry for the Environment in early 2008. Like the IPCC’s Fourth Assessment Report (4AR), their recommendations have been overtaken by recent scientific papers and data. His submission notes that modelled projections of 21st century warming rely upon two components – emission volumes and climate sensitivity. Here is his comment regarding Climate Sensitivity.

CLIMATE SENSITIVITY (Model Uncertainties)

1: THE IPCC REPORT

The 17 models used for the 4AR produced a 2100 temperature range of 1.8°C – 4.4°C. Note at page 122 of the Manual, “this arises from taking the best estimate temperature change, and subtracting 40% to get the low end, and adding 60% to get the high end of the range”. The “most likely” temperature trend is 2.7C per century. Read more… »

Around New Zealand, this scenario is increasingly unlikely. However, notice that this house was built upon sand. It’s fate was, therefore, entirely predictable, and has nothing to do with man-made global warming.

1. The IPCC Report (2007)

In 1998, the IPCC commissioned consultants – economists, futurists, statisticians, demographers, etc. – to establish story-lines of how the world might develop over the following century. This group eventually brought out a detailed book, the “Special Report on Emissions Scenarios” (“SRES”) of 40 diverse story-lines, any of which might conceivably capture the emissions profile of the 21st century.

Trenberth says the IPCC itself has no view as to the correctness of the Scenarios: “They are intended to cover a range of possible self consistent “story lines” that then provide decision makers with information about which paths might be more desirable… There is no estimate, even probabilistically, as to the likelihood of any emissions scenario and no best guess.” Read more… »

Barry Brill points out the warmists don’t seem pleased at the recent good news about climate sensitivity (a new paper says it’s not going to warm catastrophically). Could it be because the warmists cry only crocodile tears about the forecast disaster and they’re actually looking forward to it? (It lets them control us.) – Richard Treadgold

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

Whether the future level of Anthropogenic Global Warming is dangerous or catastrophic or merely interesting turns entirely on how “sensitive” the climate is to carbon dioxide emissions.

The key sensitivity measure is the increase in temperature resulting from a doubling of the CO2 atmospheric concentration of 280ppm that is said to have existed in pre-industrial times.

Laboratory experiments have shown that sensitivity should be about 1°C before feedbacks – but the net impact of positive and negative feedbacks is the subject of incessant debate. Sceptics generally say negatives (especially clouds) are dominant so that the final outcome falls back to about 0.4°C. The majority view is that positives (especially water vapour) drive the outcome up to 3-4°C, while some catastrophists see runaway warming up to 6°C or above.

There is no consensus.

The science is not settled. The debate is not over. Read more… »

It’s not possible even to keep track of the alarmist stories about climate, far less to refute them all. But when one is personally cited close to home and statements are wrongfully attributed to one, one ought to address them. This Laking/Herald howler is a case in point. Laking has taken his information from the Hot Topic side of the tracks without verification, not knowing the distortions of Renowden and friends (no matter how often corrected) and must now suffer the consequences; the formerly revered Herald similarly. My good friend Barry Brill here humorously draws our attention to the doctor’s faux pas. Regular readers will know that Richard C and Andy already mentioned the Herald article in comments on our Brash post. Thanks, guys. Apologies – one is only just getting around to it – but a refuting post will follow this. – RT

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

The NZ Herald runs climate alarm propaganda in every shape and size, and from every imaginable point of view. But it was scraping the barrel with its recent patronising but content-free sermon from a certain George Laking – presented on its weather page under the heading of “Epsom and climate change”.

Laking is apparently an oncologist. He transparently knows nothing whatever of meteorology, and even less about economics – and therefore relies upon a quote from an IEA economist to define the state of the science. He then buttresses his scientific bombast with other strongly-held opinions from non-scientists – the World Bank, UK Ministry of Defence, the Medical Association, and the World Health Organisation.

Each one of his sources has heard a real scientist say something, somewhere, about climate science. And they are almost sure they can remember part of what was said. But, says George, global warming isn’t about science anyhow, it’s about MORALITY!

If you want to know how morality works, ask a cancer doctor. George has seen what tobacco sellers got up to and he wouldn’t be a bit surprised if climate sellers weren’t just as bad.

And it turns out George’s medical training also left him well-versed in the need to manipulate raw data to get the result you are after. He says:

“If you take the raw temperature recordings alone (like ACT or… Richard Treadgold did), you won’t see a temperature rise. But that is because the readings have to be corrected for changes in site location, exposure, and instrumentation. Treadgold overlooked this and so ACT constructed a whole court case on the most abysmal scientific howler.”

Hmm. George obviously doesn’t read very much in pursuit of his climate hobby. He certainly doesn’t express any methodological preferences as between Salinger (1981) and RS93; or even NIWA’s 2010 review versus the audit published by the NZ Climate Science Coalition. He doesn’t even differentiate between the old 7SS and the NZT7.

Poor George seems to think Richard Treadgold is helping ACT to sue somebody in Epsom. Perhaps the teacup taper?

Does the Herald read these Op-Eds before publication, or is a burning zeal to hurl abuse at non-believers seen to be a sufficient qualification?

The moment of the sudden earthquake where none had been known before. Click for larger version.

From the Christchurch Press today comes alarming news:

Rising sea levels are a greater threat to Christchurch’s seaside suburbs than previously realised, a climate scientist is warning.

Speaking at Canterbury University this afternoon, Jim Salinger said latest estimates could have major implications for Christchurch’s earthquake rebuild.

Christchurch City Council should be working to a one-metre estimate for sea level rise, he said.

“It’s the opportunity for Christchurch in its rebuild, it should be looking at at least a metre. Some local bodies in Australia are using one metre.”

Salinger plucks the same alarmist harp strings he’s been picking for decades. He specifies one metre: does he include those places which are 500mm higher after the earthquake? They should get a discount.

But the Coalition chairman Barry Brill decisively puts this loose cannon of a climate scientist down, demanding evidence: Read more… »

Few people admire farming as we once did when we understood where this country’s wealth was created. On the contrary, farming has come under sustained attack, and from none more strongly than the National Party, once almost a fellowship of farmers and the industry’s staunchest supporter. Now our formerly admired farmers must tolerate the impending ETS tax on ruminant eructation, which farmers are helpless to reduce, yet for which they are further harassed by the modern epithet of “emitter”. As though those clean, natural gases could pollute the environment that has been creating them in vast quantities for millions of years. The “carbon tax” is a significant imposition, yet it’s hardly remarked upon except by those who strive to get it noticed and repealed — or others, apparently more numerous (certainly more vocal and popular with the media), who would gladly see it increased. The Coalition here rails against the unreasonable burden of an ETS which purports to “fight” in our name against so-called “anthropogenic global warming”. Do we still call it that? I guess this month’s stupid synonym is “climate disruption.” But since climate never goes for long without disruption the term defines tautology — how completely brainless to then declare it a crime and seek a culprit.

Global agreement transcends environment.

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

When the Kyoto Protocol was signed in 1997, the base year for calculating emissions was back-dated to 1990. They knew then that the ratification process would take many years (it was actually completed in 2005), so why did it hark back to the distant past?

EU

Two big European events occurred in 1991. As a result of the Soviet collapse, heavy industry had closed down in droves throughout the East. And North Sea gas came ashore in the West with a “dash to gas” displacing coal power in the UK, Netherlands, Germany and Denmark.

At the time of the Berlin COP in 1995, EU countries collectively had enough past credits from the 1991-94 period to cover all the obligations they later accepted under the Protocol. It was a no-brainer for them to demand that other developed countries match the EU misfortunes during “the First Commitment Period.” Read more… »

Barry Brill’s sharp analysis brings the ridiculous, unsustainable logic of the Hon Nick Smith under a scrutiny it cannot weather — and that’s without even mentioning the absence of scientific support for the theory of dangerous anthropogenic global warming. What warming? What sea level rise? The sooner John Key’s cabinet realises how Key and Smith have been leading them a nonsensical climatic dance around our trading image and the chance to make a quick buck from trading in the empty-headed, vaporific “carbon credits” the sooner we can eliminate the expensive bureaucratic carbon footprint we’ve acquired for reporting our Kyoto compliance (this press release first published on Scoop).

“The Caygill Review’s recommendation for doubling the current emissions trading scheme (ETS) energy levy over the next three years may be acceptable to the Minister for Climate Change, but it is certainly not acceptable to the people of New Zealand,” said the Hon Barry Brill, chairman of the New Zealand Climate Science Coalition.

“The Government’s constant refrain has been that New Zealand will not try to be a world leader and that Kiwis will never be forced to do more than their ‘fair share’ in reducing emissions,” said Mr Brill.

“But what’s ‘fair’ about the ETS?” Read more… »

Warwick Hughes’ request under the Australian Freedom of Information Act (FOIA), has been declined by the Australian Bureau of Meteorology (BoM) on the grounds that it might divulge information supplied “under an obligation of confidentiality” by a foreign Government to the Australian Federal Government.

The Court ruling which established this exemption to the FOIA dealt with a case involving intelligence-sharing with the Australian Security Intelligence Office (ASIO). In contrast, Mr Hughes’ case dealt with old weather records.

Several questions arise

1. Did NIWA impose an obligation of confidentiality on the Bureau?

It seems clear that neither party even thought about confidentiality until the request was made. Read more… »

Barry Brill, OBE, chairman of the NZ Climate Science Coalition, former Minister of Science and Technology and former Minister of Energy, thoughtfully offered the ETS Review Panel some assistance in sorting out the issues. He sent the following letter on 28 February to David Caygill, chairman of the ETS Review Panel. Seeing the sharp Brill intellect delineate the economic and political issues with his usual surgical accuracy we await the panel’s Issues Statement with keen interest. Let’s hope the panel approaches its duties with the larger portion of at least one mind still open.

almost — they just want to decide describe the issues

Dear David

I understand that the Review Panel intends to publish an “Issues Statement” prior to undertaking its proposed consultation process on the ETS Review 2011. This will presumably provide a summary of the key issues seen to be raised by the Review’s terms of reference – and might also present the Panel’s preliminary views on some or all of those key issues.

I would like to put forward some suggestions regarding 10 matters the Panel might consider appropriate for inclusion in the Issues Statement.

HELPING NEW ZEALAND TO DELIVER ITS ‘FAIR SHARE’ OF INTERNATIONAL ACTION TO REDUCE EMISSIONS, INCLUDING MEETING ANY INTERNATIONAL OBLIGATIONS

Expectations of international negotiations have changed enormously since the ETS legislation was before Parliament in November 2009. In particular:

• USA, Canada, Japan and Australia have all rejected their proposed ETS mechanisms.
• No other country has enacted any form of ETS since the EU in 2004.
• No other country has sought to suppress emissions by ‘putting a price on’ motor spirits; or on any greenhouse gases other than carbon dioxide.
• There is now little prospect of any ‘second commitment period’ under the Kyoto Protocol.
• No legally binding international treaty is likely to be agreed within the next few years. Read more… »

Monthy Python’s dead parrot sketch is famous around the world and still funny. It provides an enduring, oddly acceptable image of death. Just like the death which suddenly overtook the old “official” NZ temperature record which NIWA were defending all year up until, oh, quite recently. But their defence of it died too. Shrivelled up, suddenly dessicated.

Stone dead

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

NIWA’s long-defended ‘Seven-station Series’ (7SS) is as dead as the parrot in Monty Python’s famous sketch… it rests in peace, bereft of life, demised; it has shuffled off its mortal coil, its metabolic processes now history.

On the eve of Christmas, when nobody was looking, NIWA declared that New Zealand had a new official temperature record (the NZT7) and whipped the 7SS off its website.

NIWA’s spin-doctor, Network PR, likes to pretend that the NZT7 is really only a ‘revised’ version of Jim Salinger’s original 7SS. So when does a revision become a replacement? Read more… »

No dice — or are they loaded?

Loaded dice for temperature record?

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

In producing a new temperature record for New Zealand (NZT7), NIWA has again adjusted the raw measurements. Whilst no systemic error was found, one-off issues were raised by random site changes, especially during the early decades of the 20th century.

Curiously, NIWA’s adjustments are not random. Instead, their changes display a near-perfect symmetry, where amplitude is directly proportionate to age. Small adjustments apply to the 1950s, grow larger back in the 1940s, and larger still in the 1930s – before reaching their apogee in 1910-20.

Could this have happened by chance?

The Australian Bureau of Meteorology gives less than sunny support to NIWA’s review of the NZ temperature record. As heat, it’s distinctly tepid. As illumination, it leaves us firmly in the dark.

Constrained support

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

The Australian Bureau of Meteorology (BoM), like the National Institute of Water and Atmospheric Research (NIWA) in New Zealand, is an advisory group of Government scientists responsible for the compilation and maintenance of official temperature records.

After NIWA scientists rewrote the official NZ temperature record — the Seven-Station Series — during 2010, their ‘Review Report’ included a letter of support from the BoM. This was seen as necessary, as NIWA’s credibility had been somewhat strained by its lengthy (and ultimately futile) defence of the old record.

Some are critical of the selection of the Bureau to review work by NIWA, as both groups have been widely criticised (especially in the blogosphere) for applying the same biases and questionable adjustment methods. See, for example, Australian Temperatures in cities adjusted up by 70%!? at Jo Nova’s blog.

As climate archivists, both agencies are extensively engaged in the work of the IPCC; and both are firmly of the school of thought led by Professor Phil Jones, head of the Climatic Research Unit at the University of East Anglia (UEA).

The NZ Climate Science Coalition wrote to Science Minister Wayne Mapp, suggesting the appointment of two genuinely independent reviewers, and putting forward names of highly regarded scientists and statisticians. Read more… »

The Ministry for the Environment NZ climate impact map (a digression this, to be sure, but it must be said) — pure fiction, created to frighten children, the scoundrels! Why have they stopped using the tried-and-true method of examining historical weather records to predict the limits of future climate? Why do they trust the output of computer models when they are unverified and their predictive skill is zero? If the models give skilful predictions, why does the IPCC give us umpteen possible futures and tell us: “pick one”, saying “we don’t make predictions”? Why do they believe the models when the IPCC declares that our scientific knowledge of the climate is “poor”? In other words, we don’t have a clue how the climate works — so we don’t know if we dominate the climate. Our Environment Ministry should explain themselves then start thinking for themselves and not just believe uncritically what issues from Greenpeace and the IPCC.

The warming that wasn’t

by Barry Brill

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.
