If you have been following the story of the Akademik Shokalskiy, you’ll know it’s a global warming boat stuck in an Antarctic ice pack. What piqued my curiosity was that the expedition is called ‘Australasian’. Now, I don’t mind when Aussies make absolute fools of themselves, but when Kiwis are involved in the foolishness, I get brassed off. More so when the stupidity is funded by my taxes. Read more… »
“The situation has become such that many Sherpas in the region do not even want to hear the words ‘climate change’.”
The Mount Everest region’s Sherpas have said they are angry at the way studies of glaciers and glacial lakes have been conducted in recent years.
They say the studies do not involve them and that results are often spread through alarmist media reports that cause panic among locals in the area.
From Australian Climate Madness – h/t Val Majkus. This is a savage attack on Professor Michael Mann, author of the deceptive “hockey stick” graph published in the Third Assessment Report by the IPCC in 2001. It was the second graph in the report and much used in the publicity material until strong opposition appeared and the graph vanished for a while. Mann has hit back with a lawyer’s letter. It could get interesting for what for the first time would come under the judicial microscope.

If this goes the distance, it will certainly be worth following very closely.
Mark Steyn, writing at the National Review (backup WebCite link here), made a number of comments about Michael Mann regarding the Hockey Stick, and Mann has responded with a three-page lawyers’ letter threatening defamation proceedings (see here: page 1, page 2, page 3 – originally published on Mann’s Facebook page, reproduced here for ease of reference).
The interesting point here is Read more… »
A new study shows modern temperatures are not unprecedented and disproves an important part of Mann’s “hockey stick” paper of 1999.
Orbital forcing of tree-ring data, J. Esper et al., says:
“… large-scale near-surface air-temperature reconstructions [specifically the hockey stick] relying on tree-ring data may underestimate pre-instrumental temperatures including warmth during Medieval and Roman times.”
This is beautiful.
When the Herald reported that an “‘Abrupt increase’ in CO2 absorption slowed global warming” the first question it raised was what sort of increase was an extra “one billion tonnes of carbon per year”. It said:
The earth would have warmed faster in the last two decades had there not been an unexplained rise in the amount of carbon dioxide being absorbed on land, scientists believe.
Fortunately, Jo Nova and David Evans have commented. David describes the billion tonnes of carbon as insignificant. Jo mocks the implication that our selfish warming would have been worse without this previously unknown factor. Read more… »
Paul Mulshine says it well:
This guy nails it.
The movement to use a theoretical threat from atmospheric CO2 to control other humans is a religion, not a science.
He says the issue is the role of CO2 versus cosmic rays in cloud formation, and “it can be resolved only by physicists, not the crowd I like to call ‘climate scientologists’.” He cites an article about Henrik Svensmark by Robert Tracinski.
Svensmark, says Tracinski, “has already broken the claim of the man-made global warming “consensus” to be the only scientific explanation of the climate.”
Ignoring the past is precisely what [the alarmists] have done. Read more… »
Yes, the ocean has warmed; no, it’s not ‘global warming’
And warm water does not sink
Oceanographer Dr Willem de Lange has referred us to a really clear treatment of ocean warming and ocean-atmosphere interaction in an article by a noted oceanographer (now deceased). It appeared in 21st Century Science & Technology magazine in 2000 and carried the “Yes, the ocean has warmed” headline you see above. Though written 12 years ago, it makes a solid rebuttal to the substance of the modern warming scare, emphasizing, as though marine scientists needed to be told, that warm water cannot sink.
The author was Dr. Robert E. Stevenson, an oceanography consultant, who trained NASA astronauts in oceanography and marine meteorology, was Secretary General of the International Association for the Physical Science of the Oceans from 1987 to 1995 and was an oceanographer for the U.S. Office of Naval Research for 20 years.
Here’s the article’s original introduction:
Contrary to recent press reports that the oceans hold the still-undetected global atmospheric warming predicted by climate models, ocean warming occurs in 100-year cycles, independent of both radiative and human influences.
Which echoes today’s headlines about ocean heat content trying to explain why climate models don’t predict the climate. Read more… »
An unimaginable proposal
“As a result — and for reasons that remain unexplained — the waters of the Southern Ocean may have begun to release carbon dioxide.”
Scientific American makes the most illogical statement I’ve heard in a while.
If there’s no reason for this event, why would one propose it?
An event is proposed for which no cause can be imagined. The author proposes something he has no reason to believe — or proposes something but can’t imagine why. This is nuts. It’s not science. 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… »
From Stephen Goddard at Real Science last May (h/t Bob Carter) came this astounding climate forecast from Dr Leona Libby in 1979, just as the global warming scare was starting out.
I’m not sure it’s tracked the actual climate tremendously closely, but there are strong indications (from several horrendously cold northern winters and this last miserable southern summer) that cooling is the new trend.
Libby’s forecast would bear much wider study instead of being ignored for the man-centric theory du jour. Anecdotal evidence and observation suggest this forecast hasn’t been refuted by the theory of dangerous anthropogenic emissions-induced global warming.
On the contrary, the evidence this century is irrefutable that natural variation has been overwhelming the undetectable anthro influence. Read more… »
Thanks to those who advised me of this amazing email from the Climategate 2 collection, either through comments here or private email. It concerns the pre-1930 cooling of the New Zealand temperature record, and makes food for thought, especially for those supporting NIWA, Salinger and the increasingly shaky AGW story. Although it’s more of a novel, and a bad one at that, with gaping holes in the plot and evidence so carelessly thrown together it fools nobody. Now, as many of us feared was the case, comes evidence that the NZ temperature record has been applied to far more places than where it was observed. We now know it was stretched over far-flung places it was never intended to go. This is the worst result possible.

from: “Tim Osborn”
subject: New Zealand summer temps
just a quick Q before I go to bed!
I’ve just updated the IPCC paleo chapter Southern Hemisphere plot where we
showed, amongst other things, Ed Cook’s New Zealand TRW reconstruction,
with CRUTEM2v Jan-Mar smoothed temperatures.
For my update I’ve used CRUTEM3v, expecting them to be rather similar but
with a few more years on the end.
But the pre-1930 temperatures are now very different, being much cooler
(by > 0.5 degC for a 25-year low-pass mean) in CRUTEM3v than CRUTEM2v.
Previously they had been, on average, near or even above the 1961-1990
mean, now they’re at -0.5 degC.
Is this a result of some homogenization work on New Zealand summer temp
data? Or just some random artefact of minor changes somewhere?

Errors in the new 7SS
The shocking breakthrough in our audit is that NIWA didn’t use the adjustment method they said they would use. Barry Brill, chairman of the Coalition, released an overview entitled New Zealand Unaffected by Global Warming (pdf, 1.3 MB). The discovery that the country hasn’t experienced global warming is another startling finding. In Chapter 8, on page 24, he identifies nine criticisms of NIWA’s newest 7SS. These multiple defects destroy the credibility of the 7SS as a source of the NZTR. Read more… »
In July last year the NZ Climate Science Coalition published an independent analysis of NIWA’s reconstruction of our national temperature record (NZTR) entitled New Zealand – Unaffected by Global Warming.
It’s the only independent analysis carried out on the reconstruction (nobody else has bothered). As far as I know, nobody much has even read the report. So we need to tease out some of the details and start talking about them. They’re a bit startling, considering the diet of alarm we’ve been getting from the news media for the last twenty years.
What would Kiwis do if they knew the facts of the country’s temperature record? Would they demand the government ditch the ETS because there’s no reason for it? Would they march on Parliament?
Because one of the insights from our expert analysis is that there’s been neither unprecedented warming nor strong recent warming in New Zealand, despite claims of both from the alarmists. Read more… »
This came up a few days before Christmas. I didn’t get to it then but it needs airing. The surface temperature series of GISS and HadCrut are scarcely worth the disk drives they’re stored on. No wonder the records show warming.
It’s a joke. The shocking truth is that the oldest readings have been cranked way down and later readings artificially lifted to give a false impression of warming. That seems familiar — now where have I read that before…
NOAA changes old temperature records every month. This is a new climate sport in which we imagined Kiwis led the world. But the Yanks have more stamina. They don’t just do it once, they keep on doing it. The data-altering champions in NOAA and NASA put the climate scientists in NIWA to shame. Read more… »
Hand-in-hand with the IPCC theory that we’re dangerously changing the climate go many inaccuracies, distortions and outright lies supporting its stupendously false diagnosis, ruinously expensive remedies and tyrannical administration.
The distortions have wormed their way into thousands of places, both public and private, open and secret, taking our taxes and governing us in ways we’re already forgetting, even if we knew when they began. Will we ever be rid of them?
For to destroy each of the distortions, you need time and patience to find references to, references against and develop a refutation. Then you wait for people to hear about it and agree with you. It’s slow work.
Here’s one of the lies: mankind is ruining a perfectly good climate which never changed before we came along. Read more… »
David Archer, contributor at Real Climate, gives much reassurance today about the dangers of methane clathrates. Interesting article, with lots of things I hadn’t heard of. Nice of him, too, to put our minds at rest.
I wonder why he didn’t explain all this long before now, about ten years ago or more? Why he let all the wild, alarming speculation continue in the world’s press and in the blogs for quite so long. Why he let us worry for so long. Why, especially, he now calls us “friend” (see the end).
He says the ocean hydrates are “mostly so deep in the sediment column that it would take thousands of years for anthropogenic warming to reach them.” Well, that’s a good piece of sense, David; thanks for bringing it up. I’m sure some of us have said so already, but good of you to confirm it. Read more… »
I am sent this snippet of correspondence that refers intriguingly to continuing research into the effect of clouds on the climate. No, I won’t say who’s speaking.
Your reference to clouds led me to the work of Prof Roger Davies, who holds the Buckley-Glavish chair in Climate Physics at Auckland U.
He is part of a global group triangulating cloud data from a dedicated satellite, and seems to be developing a view that clouds provide a natural thermostat function (which Richard Lindzen has previously speculated about).
This comes from a 2008 article “Watching the Clouds” in the science faculty magazine:
Over the past eight years of data, there has been little change in the clouds over much of the Earth. However two regions stand out as exceptions. Near the equator, where the high clouds that determine the greenhouse effect are especially numerous, the cloud cover has dropped in height, suggesting a lowering of their greenhouse effect, potentially to offset global warming.
In addition, the reflectivity of the Arctic has changed. In northern summer 2006, the reflectivity of the Arctic decreased significantly, due to less cloud cover and less ice in the area, both of which reflect sunlight. However, from the ground, only a moderate decrease in ice was seen compared to its normal summer melt. The following year, there was a significantly higher ice melt than predicted, despite the fact that satellite pictures were brighter than average, and much brighter than the previous summer, due to increased cloud.
But was the 2007 melt due to the darkness of 2006? Were the clouds of 2007 compensating for the low ice reflectivity to keep a balance? Right now, we don’t know enough to say.
Interesting, but Google shows up nothing recent. He generally seems to keep his head down.
Here in New Zealand, the NZ Climate Science Coalition has battled for several years to understand the national temperature record and get the data released that lies behind it. Now we battle to correct it.
Because NIWA, in “reconstructing” the record, manages miraculously to lower past temperatures and increase recent ones to create a spurious warming that overstates the actual national warming over the last hundred years by 168%!
We’ve told NIWA about it and we’ve sent them our report that proves it, but they refuse to acknowledge our finding, much less explain themselves. It is a national disgrace which our newspapers, magazines, radio stations and television channels strangely refuse to investigate.
The warming is truly man-made, for it hasn’t happened in the real world, it has been created only by the adjustments.
Now, from C3 Headlines, we learn that an even more invidious process has been going on in the United States. Read more… »
This is surely too good to be true for the warmists.
In the last few days of a failing international conference, here’s a paper carrying strong confirmation of global warming. It’s not attribution, of course, but nobody will notice that. Proof of warming is enough to tweak the guilt nerve.
The Washington Post says:
The global temperature series is one of the clearest pieces of evidence that the planet is heating up. Over the past century, it’s easy to see from, say, NASA’s data that surface temperatures have risen dramatically. But there’s also a fair bit of short-term natural fluctuation from year to year, which can sometimes obscure what, exactly, is going on.
Climate crisis called off
The Intergovernmental Panel on Climate Change (IPCC) has published the Summary for Policymakers (SPM) to a Special Report, Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX). (Actually, they haven’t.)
The SPM (I’ll call it the “report” from now on) is remarkable in its candour. The IPCC, once wanting to become the world’s evil overlord, with fingers in public and private pies everywhere to compel compliance with its anti-carbon agenda, acknowledges its ignorance and uncertainty about the climate.
The evil giant has finally spewed forth something wholesome. Read more… »
Earth’s temperature has never been taken, actually
A story, Analysis confirms global warming data, accounts for urban heat islands, appeared in the Science Media Centre (SMC) on 21 October. I missed it then, but it’s been brought to my attention in correspondence within the Climate Science Coalition.
A member saw the SMC story and commented:
Wratt and Renwick are quick to assert that this non-peer-reviewed temp study reinforces their suspicion that UHI is an insignificant factor. They both refer to numerous other authorities. I thought the leading paper supporting this view was Phil Jones’ China study of about 1991, which he has recently admitted to be based on a mistake. Are there any others which debunk UHI?
This raises several interesting elements which I’d like to follow at some time, but it also prompted this succinct analysis from the evergreen Dr Vincent Gray, who responded: Read more… »
Climate Realists carried a letter from John O’Sullivan on 2 November, claiming ill treatment at the hands of Suite101.com, in terminating their publishing arrangement with him. I note that two of O’Sullivan’s articles are still available at Suite101 but this is his letter:
I write to announce my employment with my publishers, Suite101 was terminated today without prior notice or explanation and all my articles published over a two-year period with them are now removed from the Internet. I believe this is in retaliation for my latest article ‘New Satellite Data Contradicts Carbon Dioxide Climate Theory’ revealing the shocking fact that the Japanese ‘IBUKI’ satellite measuring surface carbon dioxide emissions shows that Third World regions are emitting considerably more CO2 than western, industrial nations. Read more… »
Now where should we start?
How confusing is this?
Climate Realists announce that new satellite data from Japanese scientists show carbon dioxide is emitted mostly by the third world, with much less coming from industry in the west. For those asleep in the back, that’s the reverse of our previous understanding (so it’s a confusing result). On the map, pink is where emissions are occurring, green is where absorption is occurring.
Life is now officially upside down — the giant northern hemisphere economies are not emitting CO2 after all, they’re absorbing the stuff! Read more… »
It’s hard to know what to say about Tom Wigley’s new paper on the climatic repercussions of replacing coal with natural gas: he says gas and coal are both good, and they’re both bad, but the truly remarkable thing is that, where for years the greens have been telling us to hate coal and everyone who uses it, now it’s hard to choose between coal and gas.
It doesn’t matter whether you believe mankind is warming the planet dangerously or not, Wigley tells us that it makes hardly any difference to the warming whether you use gas or coal. So why switch to gas? There’s no advantage in it. Read more… »
Two days ago we heard about the long-term trend in atmospheric carbon dioxide emissions, copied above.
This graph functions as a fine graph of productive output, and doesn’t it reveal the new world order? The countries with the highest emissions are (broadly speaking) doing the most work, making the most money and having the most influence.
It was ever so. If our leaders wake up to that simple fact they might be able to make sensible plans to maximise our work. Perhaps improve on the half-baked notion of a magic “knowledge economy” — as though knowledge alone would succeed without the application of intelligent planning, consistent effort and good service.

From today’s Summit County Citizen’s Voice, we read Bob Berwyn’s account of Kevin Trenberth’s favourite paper so far this century.
Global warming: ‘Missing’ heat found deep in the ocean
Changes in ocean currents and circulation are capturing some of the sun’s incoming heat deep in the ocean, according to researchers with the National Center for Atmospheric Research, who said their latest computer models account for some of the global warming heat that’s “missing” from land and sea surface temperature readings.
This implied that heat was building up somewhere on Earth, according to a 2010 study published in Science by NCAR researchers Kevin Trenberth and John Fasullo.
Observations from a global network of buoys showed some warming in the upper ocean, but not enough to account for the global build-up of heat. Although scientists suspected the deep oceans were playing a role, few measurements were available to confirm that hypothesis.
To track where the heat was going, Meehl and colleagues used a powerful software tool known as the Community Climate System Model, which was developed by scientists at NCAR and the Department of Energy with colleagues at other organizations.
Well, well, who would have thought? All the missing heat, safe in the ocean deep, alive and well, having nipped through the upper reaches of the ocean without warming it. I never guessed — did you? Truly amazing.
But there’s no data, just more modelling
The computer game doesn’t care about realism, so the lack of any plausible mechanism whereby the heat might have reached more than 1000 ft (305 m) deep while leaving the upper levels unwarmed didn’t affect its findings.
When the game “found” extra heat deep in the ocean, there was nothing to say “that’s impossible.”
So, because they’re real scientists, we can expect an announcement very soon of a new study aimed at discovering how the missing heat got to where it was found.
One day they’ll get around to actually observing the climate effects they report. When they do, you can read about it here!
Independently peer-reviewed scientific papers published in learned journals are the Holy Grail of climate science alarmists, and the IPCC in particular. So they want to get friendly papers in and keep contrary papers out.
The Climategate emails show continuous collusion between members of the “Hockey Team” to prevent journal publication of any paper which challenged the IPCC dogma. Because, once published, a paper becomes part of “the scientific literature” and authors are obliged thereafter to take it seriously.
Of course, the IPCC manipulates the system outrageously. After Chairman Pachauri assured the media that it disregarded non-peer-reviewed opinions, revelations came that more than one-third of the material used by some Working Groups came from the “grey” literature (usually written by Big Green activists).
NIWA closely follows the party line. That’s why it has insisted endlessly that the New Zealand temperature record (NZTR) included adjustments “described in the peer-reviewed scientific literature” which were “in accord with internationally accepted techniques.” Read more… »
See commentary on WUWT.
Nature has just published Cloud formation may be linked to cosmic rays, which acknowledges results from an experiment at CERN probing a connection between climate change and radiation bombarding the atmosphere.
[In comments, Alan Burke quickly diminishes the significance.]
In the meantime, Nigel Calder posts CERN experiment confirms cosmic ray action, nailing confirmation of such a “connection” to the scientific wall.
You can draw your own conclusions from the revealing graph he gives:
Take your pick between Nature and Calder. Is the link alleged or confirmed? Is there a non-GHG-induced magnification of solar influence on cloud formation, and therefore global lower tropospheric temperature, or not?
This must give Nick Smith cause to review our ETS.
Stand back as the warmists rush the exits.
NIWA didn’t use Rhoades & Salinger. We can prove it. They lied.
NZ Climate Science Coalition statisticians have uncovered evidence of scarcely believable deception from our National Institute of Water and Atmospheric Research Ltd (NIWA).
Last December, NIWA released a reconstructed NZ temperature series Report on the Review of NIWA’s Seven Station Temperature Series (“7SS Review”) (pdf, 8.5 MB). It has a fresh new graph (below) that’s all but indistinguishable from the previous graph. But that’s not the point.
The point is the new series is a lie. Read more… »
NIWA’s data confirms: little warming
When it’s calculated correctly
Why did they lie to us?
In December last year, NIWA released their long-awaited review of the NZ temperature record (NZTR). We’ve reviewed that report and found serious errors. NIWA used the wrong method and created strong warming. We used the right method and found mild warming.
There are a few things we need to understand about weather stations. The first is that these stations sit there for a long time. Some of them have been in the same place for 80 years and more. If you sat in one place for that long, you’d see stuff happening around you — same for the weather station.
Trees grow, buildings go up, airport runways get covered in tarseal or concrete, roads appear, and these and other non-climatic influences affect the temperature readings, usually making them warmer, but not always. Sometimes the station gets moved, and it’s always better to keep all that history if you can, so you try to adjust it rather than start again with a new station.
NIWA had to start from scratch
Knowing this, when scientists examine a series of temperature readings they look for what has changed at the different stations. If the changes affected the temperature readings, they adjust the readings. Read more… »
HUNTSVILLE, Ala. (July 26, 2011) — Data from NASA’s Terra satellite show that when the climate warms, Earth’s atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to “believe.”
The result is climate forecasts that are warming substantially faster than the atmosphere, says Dr. Roy Spencer, a principal research scientist in the Earth System Science Center at The University of Alabama in Huntsville.
There is no statistically significant warming trend since November of 1996 in monthly surface temperature records compiled at the University of East Anglia. Do we now understand why there’s been no change in fourteen and a half years?
Well, yes, because “blame” for this interruption in warming has been placed on sulphates emitted by China’s power stations zealously burning coal. Hasn’t it?
Has this hypothesis been tested? No. Can it be tested? Yes.
Most of the aerosols are in the northern hemisphere, and there’s little mixing of air between the hemispheres. Reason tells us that the northern hemisphere should be cooling and the southern hemisphere should be warming.
Well, go on, this is the big test, look it up. Read more… »
(h/t Bob D for most of the references)
Journalist Chris Barton has a story in yesterday’s Herald titled The climate dissenter holds his ground. After looking at Barton’s alarmist arguments I’ll stand with Chris de Freitas on the solid ground.
The story begins with the implication (not that the journalist says it this plainly) that, even with the planet battling weather extremes, that is not enough to convince an Auckland climate scientist (Associate Professor Chris de Freitas, at the University of Auckland) of the truth of human-induced global warming. We’re supposed to feel exasperation: “What will it take to get that man to see sense?”
But Barton is dead wrong. For why should “extreme” weather be an indication of man-made global warming? How could we get more extreme weather out of global warming? Read more… »
A study from the University of Exeter on species decline declares “climate change warnings not exaggerated.”
However the press release leaves one singularly unimpressed with the raw activism of the lead researcher, who says: “It is time to stop using the uncertainties as an excuse for not acting.

Yesterday I saw the headline: Climate change reducing ocean’s carbon dioxide uptake. If they mean the temperature’s been rising, I thought, these guys need a lesson in 1) recent, 15-year-long atmospheric temperature non-rise and 2) the gas laws, or specifically, Henry’s Law.
Henry’s Law states that the solubility of a gas in a liquid at a particular temperature is proportional to the pressure of that gas above the liquid. If the temperature of the liquid rises, it can’t hold so much gas, so some will leave (“outgas”). It hardly requires a paper based on 28 years of observations to confirm this. Read more… »
Rash of news alerts
From News.Scotsman.com comes worrying information of rapid sea level rise.
Global warming is causing sea levels to rise at a faster rate today than at any time in the past 2,100 years, according to new research.
Scientists used the fossils left by tiny marine animals to record two millennia of sea levels along the US Atlantic coast.
Some inspired comments
In the most detailed look yet at sea level change, scientists on Monday reported that waters along the East Coast have risen far faster over the past century than at any time in the previous 2000 years. [Philadelphia Inquirer]
20th-Century sea-level rise on the U.S. Atlantic coast is faster than at any time in the past two millennia. [Real Climate]
The research confirms what has often been assumed, that there’s a very strong link between sea levels and temperatures. More worryingly, it also seems to confirm just how uniquely pronounced the current climate change really is. [io9]
With the Royal Society smoke ‘n’ sea level rise
Professor Keith Hunter, the Society’s Vice President of Physical Sciences, who contributed to the paper, says researchers are starting to be able to estimate the amount of rise that we should expect to see over this century and beyond. But he says these projections of future sea level rise depend upon the future melting of ice sheets, which is poorly known.
“The uncertain knowledge about ice sheet behaviour is the key reason why IPCC projections in 2007 did not state upper bounds for sea level rise. Similarly, Ministry for the Environment guidance in 2008 wisely left open the question of any upper limit on sea level rise.”
The paper states that some early scientific work into the effect of a warming climate on ice sheets in Greenland and Antarctica suggested that many metres of sea level rise could occur within a century. However, it says few scientists now consider that such rates are possible.
What do we learn from this?
We learn that we can’t guess future sea level rise, since we can’t guess future ice sheet melting; our mates at the UN and the MfE won’t touch it, and our first guess was several metres but now only the cranks go that far.
The press release expresses complete ignorance on future sea level rise. Great. So we also learn that scientists can make complete ignorance appear very interesting. Read more… »
Science story of century
Mini Ice Age on way?
Strange happenings in the sun
End of global warming?
At WUWT Anthony Watts announces: The American Astronomical Society meeting in Los Cruces, New Mexico, has just made a major announcement on the state of the sun. Sunspots may be on the way out and an extended solar minimum may be on the horizon.
“This is highly unusual and unexpected,” Dr. Frank Hill, associate director of the NSO’s Solar Synoptic Network, said of the results. “But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation.”
Spot numbers and other solar activity rise and fall about every 11 years, which is half of the Sun’s 22-year magnetic interval since the Sun’s magnetic poles reverse with each cycle. An immediate question is whether this slowdown presages a second Maunder Minimum, a 70-year period with virtually no sunspots during 1645-1715.
“We expected to see the start of the zonal flow for Cycle 25 by now,” Hill explained, “but we see no sign of it. This indicates that the start of Cycle 25 may be delayed to 2021 or 2022, or may not happen at all.”
All three of these lines of research to point to the familiar sunspot cycle shutting down for a while.
“If we are right,” Hill concluded, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.”

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… »
All of the 159 documents in BoM’s “Schedule” are said to be communications received in confidence by the Australian Federal Government from a foreign Government.
They simply cannot reconcile that claim with these actual Bureau descriptions:

In Australia, Warwick Hughes has followed with interest our attempts to obtain from NIWA details of their adjustments to the NZ temperature record. When the Bureau of Meteorology (BoM) supplied a letter apparently certifying the Bureau’s “peer review” of NIWA’s review of the temperature record, he noted our complaint that “there must be more than this.”
Hearing of my request to NIWA for records relating to that review by the Bureau, he was minded to help. So, back in February, he filed a Freedom Of Information (FOI) request with the Australian Information Commissioner.
In response to that FOI request, the Bureau submitted to the Information Commissioner a Schedule of Documents dated 6 May 2011.
Somebody at the Bureau has put in hours of work tracking these documents down, describing them, analysing their relevance to Warwick’s request and assessing whether they met the provisions for exemption. Well done, them.
The schedule describes 159 relevant documents, amounting to several thousand pages, and what do you know? The BoM claims full exemption from the FOI Act in respect of Read more… »! Who could have predicted that?
What a secret!
See UPDATE, below.
Here’s a development that threatens to place publicly-funded weather data on the same footing as the next budget, or troop movements.
In February, Warwick Hughes lodged a Freedom Of Information request to the Australian Bureau of Meteorology to release all documents connected with their peer review for NIWA of NIWA’s review of their seven station series (7SS).
Today, Warwick posted a story about it, Australian FOI law keeps secret the construction of New Zealand seven station temperature series.
What’s so secret about temperature records?
In frustration, Warwick laments: “I am hoping that people smarter than I might see ways to carry on the battle to get these papers and files released. What can be so secret about the things publicly-funded scientists and bureaucrats do to adjust common or garden weather records into a form that suits them? We are not talking about nuclear weapons secrets here.”
I agree. Let’s hope someone with legal expertise and a desire to uncover the truth can pick up Warwick’s endeavour and move it forward.
The NZ situation
We’re waiting for the outcome of an investigation by the Ombudsman into NIWA’s refusal to release to me similar documents related to the peer review.
The BoM, in a document setting out their Reasons for Refusal, reveals that no fee was paid to them by NIWA for the peer review.
New report seems to assume it’s melting, but is it?
Greenland is the world’s largest island, about 2600 km long and 1100 km wide at its widest point. Most of the interior is covered by the world’s second-largest permanent ice sheet. Average temperatures rise above freezing only briefly, during the summer. Here’s a simplified graph of monthly temperatures taken from a tourism site.
Yesterday the NZ Herald reported a study finding faster melting of Arctic and Greenland ice. The scientific team thinks global sea levels could rise by as much as five feet (1.5 metres) this century. Read more… »
Water vapour more significant than CO2?
A study released last year reveals water vapour has an important role in global warming and more research is needed. When water vapour declines it seems to lead to global cooling, preventing overheating.
The story was covered in The Guardian on 29 January, 2010:
Water vapour caused one-third of global warming in 1990s, study reveals
Experts say their research does not undermine the scientific consensus on man-made climate change, but call for ‘closer examination’ of the way computer models consider water vapour.
Scientists have underestimated the role that water vapour plays in determining global temperature changes, according to a new study that could fuel further attacks on the science of climate change.
The research, led by one of the world’s top climate scientists, suggests that almost one-third of the global warming recorded during the 1990s was due to an increase in water vapour in the high atmosphere, not human emissions of greenhouse gases. A subsequent decline in water vapour after 2000 could explain a recent slowdown in global temperature rise, the scientists add. Read more… »
Accelerated sea level rise debunked
A new analysis finds evidence of a weak deceleration in mean sea level rise in the Australasian region from 1940 to 2000 in four very long-term tide gauge records.
It brings long-term confirmation to what the South Pacific Sea Level and Climate Monitoring Project (SPSLCMP) has been reporting for about 10 to 15 years — slow, non-alarming sea level rise. Read more… »
Judith Curry draws a radical conclusion from this radical paper. The authors claim that climate forcings from both human influence and natural variation are likely of similar magnitude, which is the first time since the IPCC was created that the climate establishment has expressed that possibility. Then they admit that telling the difference between them is difficult (the science is not settled). That’s the second time that’s been said (the first time was in an early IPCC report). Since “human influence” has become a hot-button code word for guilt, perhaps the guilt might now subside. Finally, Judith has a plea for the IPCC authors: “No more ‘unequivocals’ or ‘very likelys’ in the AR5, please.” Amazing — you must read this and share it with everyone you know or don’t know. It’s sober and persuasive evidence that a tide is turning — a belief in dangerous warming no longer holds a trump card in climate studies. Make the politicians face this new scientific reality or they’ll go on for years with their ETS and carbon taxes – h/t Barry Brill
Separating natural and anthropogenically-forced decadal climate variability
The issue of separating natural from anthropogenically forced variability, particularly in context of the attribution of 20th century climate change, has been a topic of several previous threads at Climate Etc. The issue of natural vs anthropogenically forced climate variability/change has been a key issue of contention between the climate establishment and skeptics. There are some encouraging signs that the climate establishment is maturing in their consideration of this issue. Read more… »
and the winner is… well, never mind: the loser is science
(Nobody’s won yet.) Now here’s more of the saga…
The ‘Seven-station Series’ (7SS) constructed by NIWA scientists claims a 20th-century warming trend for New Zealand of 0.9°C. The warming arises entirely from their in-house adjustments to the raw thermometer readings and they’re now very keen to find some corroboration for that warming.
Why are they so anxious to vindicate the 7SS? Because they’re finding it almost impossible to achieve. This conclusion of warming is an orphan — it contradicts all other official temperature records, going back decades. Read more… »
Rhoades & Salinger (1993)
The late Michael Crichton declared that ‘global warming’ had become a religion, with the IPCC reports comprising its bible. The central dogma of the religion rests on the global temperature record, which ‘proves’ recent global warming. It has a bible of its own, largely written by CRU’s “hockey team” — those conniving, partisan, anti-sceptical scientists of Climategate infamy.
Above and beyond everything else it might be, a bible inspires belief. That is the natural result of the veneration a bible gains by long use. And you don’t ignore something you venerate.
Around the world amateur, unpaid investigations reveal that recent warming trends don’t really exist. In fact, they are largely created by “homogeneity adjustments” to the actual thermometer readings. Read more… »
Here’s a thread to discuss the migration of gases (or not!) through firn, or old snow, and the ramifications for past levels of atmospheric gases. When I discover how to move comments between threads, I’ll add the relevant comments from other threads.
All right, so it might not be getting down to out-of-the-ordinary freezing temperatures, but it’s certainly not unduly warm, which is the claim we’re constantly hearing in the mainstream media, even now. Even after all the contrary evidence. Here’s more.
To show that there is scientific data backing up the refutation of strong, even dangerous, warming brought on by our over-indulgence in the famous capitalist mind-altering industrial pollutant, carbon dioxide, the NZ Climate Science Coalition just issued a press release. The 2009 paper from McLean, de Freitas and Carter shows the uncanny correlation between the Southern Oscillation Index and global temperature several months later. The press release shows how the paper “predicts” the current temperature plunge.
And I really mean plunge, because McLean et al speculate this year could be the coldest since 1956. Brrr!
Now be my guest: show how wrong it is! Show us how the correlation is not really a correlation. It’s a free world!
Oh — and you’ll also have to demonstrate, of course, that global temperatures are NOT following the SOI graph from about seven months ago (please don’t forget that part). The press release is next. Read more… »
