Jo Nova and David Evans reveal astounding new work
Will this be the magic bullet to destroy climate ignorance?
This from Jo Nova (note her lack of arrogance):
Behind the scenes, for 18 months, Dr David Evans (my other half) has been quietly working full time on climate research. The Fourier expert with six degrees who studied at Stanford has discovered something extraordinary using silicon-chip maths on the climate system. (Electrical engineers are really going to like this new approach.) This is real science laid bare. Continue Reading →
It looks like the only thing with black body radiation is a real black body and that transparent things, like gasses, are not quite the same. In particular, CO2 likes to heat up instead of emit a photon. Continue Reading →
Amid all the world-wide signs of a major sea-change in climate thinking (yes, that’s a pun) comes the encouraging news that New Zealand university students prefer the truth over activist drivel. Why did we ever doubt them? Continue Reading →
Why you won’t see headlines as climate science enters the doldrums
Posted on November 4, 2013, at Watts Up With That
Guest post by Dr. Robert G. Brown, Physics Department of Duke University (elevated from a comment on a WUWT thread: RSS Reaches Santer’s 17 Years).
This (17 years) is a non-event, just as 15 and 16 years were non-events. Non-events do not make headlines. Other non-events of the year are one of the fewest numbers of tornadoes (especially when corrected for under-reporting in the radar-free past) in at least the recent past (if not the remote past), the lowest number of Atlantic hurricanes since I was 2 years old (I’m 58), the continuation of the longest stretch in recorded history without a category 3 or higher hurricane making landfall in the US (in fact, I don’t recall there being a category 3 hurricane in the North Atlantic this year, although one of the ones that spun out far from land might have gotten there for a few hours).

Barry Brill reveals a serial deception by the IPCC we need to wake up to. Why? Because the alarm peddled by this UN body relies on a simple, easily confirmed falsehood. The IPCC claims we should adhere to a 30-year observation period it has never itself respected. It implies that we should believe the IPCC that it’s been warming and disbelieve the temperature data that it hasn’t been warming. The IPCC’s parent body, the WMO, says that a far shorter period is quite all right (why won’t they correct the IPCC?). We cannot trust the IPCC, so we must take decisions regarding the expected future climate completely out of their insincere, incompetent hands.
Under pressure at a media conference following release of its Summary for Policymakers, AR5 WG1 Co-Chair Thomas Stocker is reported to have said that “climate trends should not be considered for periods less than 30 years.”
Some have seen this as the beginning of an IPCC ploy to continue ignoring the 16-year-old temperature standstill for many years into the future. But even the IPCC must know that any such red herring is dead in the water: Continue Reading →
It can’t be over yet. When people are still being fired for not believing in global warming, it’s far from over. The war continues.
Professor Bob Carter (an expatriate Kiwi) lost his job the other day at James Cook University (JCU) in Townsville. He had worked there for 31 loyal years, his professional life devoted to stratigraphy, understanding events in the deep past recorded in ocean sediments, and teaching.
Significantly, because it led to his dismissal, Bob made an honourable name for himself and earned a world-wide reputation for remaining faithful to scientific principles while analysing the outrageous predictions from global warming alarmists. He was never afraid to speak out against the alarmists and their dubious claims. Continue Reading →
The video begins in German, but after only 41 seconds shifts permanently to English (and later American), so don’t be dismayed. Stick with it.
The German professor, in his words of welcome, describes Professor Salby, from Macquarie University in Sydney:
He is known all over the world as one of the few specialists who really have a view over the whole area of climate development. Despite his long relationship with the most renowned climate institutes, he has preserved his own critical and constructive reasoning, which in some parts is in real contradiction to the official expert opinion and also [opposes] the assessment of the IPCC.
Sorry, I’ve been trying to post this for a week. – Richard Treadgold
Wrong, but no apology
TVNZ now admits to me that its press release was wrong in claiming that Dr Renwick blamed the recent drought on global warming.
But TVNZ don’t apologise to us or the New Zealand public — or even to Dr Renwick. The Corporate Affairs Department is entirely absorbed in explaining their mistake, rather than caring that they made it.
That’s the third strike against these public relations masters.
What we object to, Andy, is not the obvious behaviour of the surface temperature record, but your continued conflation of temperature with warming. Stop claiming that “warming has stopped”, and we can move on to talk about ice melt, rapid Arctic warming, and the impact on northern hemisphere weather patterns instead of indulging in silly semantics.
At last! How wonderful. For years we’ve been saying it’s not warming — the readings aren’t going up! Can’t you see that? We suffered these stupid explanations that there’s no stasis, we still have warming, in fact (some said) warming has accelerated. Continue Reading →
It’s early to say it, but I’ll say it early — Willis Eschenbach has achieved an earth-shaking breakthrough that’ll have him hailed a hero for years to come.
His fame will live on long after he has gone. He hasn’t merely found that carbon dioxide doesn’t control the temperature. He’s provided a reason to discard the very notion that any single forcing controls the surface temperature. The climate is a complex system.
His achievement is a triumph.
The heavy lines show model response after volcanic eruptions. The response is very slow and after five years temperatures are still below pre-eruption values. In reality, real temperatures in the natural system (heavy black line is their average) get above pre-eruption values within two years and total system energy starts to recover. The models show little correlation with observations. Click for larger version.

Anthropogenic attribution to sea level rise and ocean heat accumulation relies on there being a verified mechanism or process by which rising anthropogenic greenhouse gas (aGHG) emissions impute heat to the ocean. John Cook’s Skeptical Science has been promoting one such posited mechanism in particular as explaining the accumulation of heat in the ocean over the last 40 years or so, the most prominent example being How Increasing Carbon Dioxide Heats The Ocean, posted in 2011 by Rob Painting. That post adapts a 2006 Real Climate article by Professor Peter Minnett, Why greenhouse gases heat the ocean, where an enhanced ocean surface insulation effect was posited.

Chris de Freitas is a proper scientist with a wonderful sense of humour — just wait until you see his conclusion! His articles are easy to read and I always read them.
Regrettably, the Herald has turned comments off, but that’s why blogs exist — leave your comments here where influential people will see them!
This is an adopted article.
Chris de Freitas: Science proves alarmist global warming claims nothing but hot air
Several aspects of Jim Salinger’s op-ed “Climate hurtling towards a hothouse Earth” Herald 24/5/13 are quite misleading. It is true most climate scientists would agree that rising carbon dioxide in the atmosphere due to fossil fuel use could affect global climate. The basic physics is there to support this view. But there is no evidence that the putative change would be large or damaging. Output from computer models is not evidence unless model performance has been validated. So far, it has not.

In their reply TVNZ have made an amazing error. Like a careless schoolboy failing to read the exam directions, someone didn’t read my letter properly. They’ve given a response that annoys me and will surely displease senior managers. Continue Reading →
Global Warming Policy Foundation Invites Royal Society Fellows For Climate Change Discussion
London, 22 May: In response to a suggestion by Sir Paul Nurse, the President of the Royal Society, the Global Warming Policy Foundation has invited five climate scientists and Fellows of the Royal Society to discuss the current state of climate science and its wider implications.
In a letter to Lord Lawson, the GWPF chairman, Sir Paul stated that the Royal Society “would be happy to put the GWPF in touch with people who can offer the Foundation informed scientific advice.”
Sir Paul suggested that the GWPF should contact five of their Fellows: Sir Brian Hoskins; Prof John Mitchell; Prof Tim Palmer; Prof John Shepherd and Prof Eric Wolff.
The GWPF has now invited the five climate scientists to a meeting with a team of members of the GWPF’s Academic Advisory Council and independent scientists and has proposed a two-part agenda:
1. The science of global warming, with special reference to (a) the climate sensitivity to carbon dioxide and (b) the extent of natural variability;
2. The conduct and professional standards of those involved in the relevant scientific inquiry and official advisory process.
“I hope the Fellows of the Royal Society will be happy to meet with our team of scientists so that something positive can come out of Sir Paul’s recommendation,” said Dr Benny Peiser, the Director of the GWPF.
Dr James Hansen, former respected space scientist, “father” of global warming, now an unrepentant (now full-time) activist warning of nothing less than the imminent “destruction of the world” — which at one time was the very definition of ‘crank’. It is quite difficult to destroy the life in the world and it shows no sign of becoming easier.
Yesterday, Dr Vincent Gray sent out his Climate Truth Newsletter (no. 310). In it he adverts to an outrageous admission of common sense by James Hansen. Years ago, Hansen admitted on his GISS web page that there’s no agreement among scientists on what constitutes an acceptable surface air temperature.
Sensationally, he also said that it’s IMPOSSIBLE to obtain a scientifically meaningful surface air temperature (SAT).
Now, with Hansen’s resignation from NASA, Gavin Schmidt has rushed in to take charge of these surprising admissions. Curiously, I see that Schmidt’s description is “NASA Official,” where Hansen was the “Responsible NASA Official.” Significant, interesting or irrelevant? Speculation might be endless…
The link above to the previous version of the page at the Wayback Machine is from 15 October, 2008, but that page is marked as last updated on 12 July, 2005. There are three more words in the body text of the current version than on the old page; I conclude they’re essentially identical.
These comments asserting the impossibility of determining the SAT put a disturbing slant on Hansen’s alarmism based on the SAT during the last 20 years of the 20th Century. Continue Reading →
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.
Here’s an interesting reflection on the climate system which at a stroke highlights the complexity of climate and puts to one side (at least for a moment) the belief that it must have a single controller, such as a minor atmospheric gas.
Dr Vincent Gray explained today:
The idea that the Earth has a “radiation budget” is inherently wrong.
The climate is a heat engine. The energy comes in from the sun. The exhaust goes out to space.
The exhaust must be less than the input because in between some work must be done. This would include maintenance of all living creatures plus erosion and other changes in the surface.
A scientist comments that the concept of a budget is both sound and useful, even if not strictly applicable all of the time. The energy budget approach is at the heart of modern climatology and is not controversial.
I wonder if any papers have addressed the total work done by the climate system? Continue Reading →
It crops up repeatedly: but there was no medieval warm period (MWP), therefore the modern warming is unprecedented.
The CO2 Science web site has a long-running project to examine records all over the world concerning temperatures in the medieval period. Their overview page makes a great introduction to the project. They cite material from hundreds of scientists and institutions. Really quite impressive.
So when will the warmists stop saying there was no medieval warm period?
Here’s good news for all those who despair at the defects and sheer incompetence (it seems) in the calculation of the Global Warming Potential of methane: it’s about to get a high-level airing. I emailed Professor David Frame a few days ago. Prof Frame is Director of the NZ Climate Change Research Institute at the Victoria University of Wellington, taking over from Martin Manning in October last year. He’s given us a prompt and encouraging response. – h/t Barry Brill
But I write concerning your comment following the post. There’s been much discussion at the Climate Conversation Group about the calculation of GWP for methane, what it should be and what might be done to make it more reasonable. Set too high, it is a considerable impost on NZ farming, which as you know is among the world’s most efficient. You say:
Shorter-lived gases (such as methane) are not obviously as important for the overall properties of climate change as is commonly thought, and the way we count them – or rather the way the folks who came up with Kyoto ended up counting them – masks this by giving them high emphasis. [Unwarrantedly high emphasis in my view, but that would be another article, which is a bit more technical to write.]
The turbulent science that blames humanity for climate change marks itself with smoke and mirrors. Opportunities to settle the truth are somehow sidelined. Tricks are employed to obscure the truth. When direct measurements show a negative temperature trend, indirect methods are sought to show the desired warming.
Then it is that we hear that polar ice is disappearing, polar bears are in peril, coral reefs are bleaching, there’s more rainfall, less rainfall, seasons are being disrupted, extinctions are occurring, glaciers are retreating, there’s more extreme weather, and on and on.
But these events, where true, and they often are simply untrue, are influenced by factors other than warming, so the believers also use slippery reasoning to pretend they’re caused by warming. We’re fed stories of disaster that could only be true if the temperature were going up, but it’s propaganda: when the science fails, the believers resort to misdirection. Even if it were warming, so what? What’s the cause? Believers never address the cause of warming – though that’s essential if we’re trying to stop the warming – because by now everyone thinks it’s themselves.
Rather than taking tales of alarm at face value, we try to investigate them. So to the humble North American Mountain pine beetle…
Mountain pine beetle.
The Mountain Pine Beetle is tiny — about 5 mm long (same as the word “tiny”), but it packs a mighty punch: it can flatten forests.
The little beetles make interesting reading in the light of claims that the current outbreak in parts of the USA and Canada is caused by global warming.
Steve McIntyre reaches new heights in his resolute scrutiny of climate science and raises the bar for fellow sceptics. For the lead author of a new paper has acknowledged McIntyre’s work in identifying an error so serious it may alter the paper’s results and has certainly forced a delay in its publication.
But note that although McIntyre “also” identified “this data processing issue”, he wasn’t first – the team beat him to it.
Here’s an argument against the validity of climate catastrophe, straight out of the “too good to be true” basket. It goes something like this:
“After several centuries of humanity’s meandering technological development, the odds are remote that, at precisely the time of our demise, we developed computer hardware and models sophisticated enough to predict our imminent demise.”
Computers are now sophisticated enough to model our demise but not so sophisticated that they know more than we do. The likelihood of our demise actually being imminent is vanishingly small because:
We don’t know how the climate works.
There’s been no warming since 1995, despite a 20% increase in CO2.
The atmosphere (since 2001) and the ocean (since 2004) have been cooling.
Models fail hindcasts, thus inspiring no confidence in their forecasts.
The IPCC, from whom the government takes its advice, is utterly discredited.
There’s been no alteration in natural rates of sea-level change.
We don’t know how the climate works.
But don’t believe me – ask any climate scientist (warmist or sceptic) and they’ll tell you we don’t know how the climate works.
But if you studied it, why did you never deny the claim that it was settled?
Climate scientists of New Zealand: you have deceived us.
The RSNZ is planning to announce progress in climate science since the AR4 in 2007.
Since 2007 and earlier, from Al Gore down, these arrogant shouts around the world have escaped challenge by the scientific establishment: “the science is settled” on climate change! The claim has been around for most of the century.
The Royal Society of New Zealand has never, to my knowledge, used the phrase “the science is settled.”
It did set up the government-funded Science Media Centre (SMC), with its Sciblogs department, which re-blogs numerous odious posts from such celebrated centres of scientific excellence as Hot Topic and Open Parachute. And those blogs and their manic commenters provide all the spittle-lipped propaganda you could ever wish for the “settled science” believers without needing contributions from the respected scientists at the RS.

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.”
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.
Having completed the post, I’ve discovered the new Levitus paper. How does Levitus et al. 2012 compare with the old Levitus et al. 2000? The new paper is in press, so we only have the abstracts to compare. In 2000, the heat content of the world ocean increased by ∼2 × 1023 joules between the mid-1950s and mid-1990s, representing a volume mean warming of 0.06°C. In 2012, the heat content of the world ocean increased by 24.0 × 1022 J for 1955-2010, corresponding to a volume mean warming of 0.09ºC.
With 24.0 × 1022 being 20% greater than 2 × 1023, and the temperature going from 0.06 to 0.09°C giving an increase of 50%, we have a familiar picture. It’s deja vu, only warmer.
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. Continue Reading →
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.
– by Barry Brill, Chairman of the New Zealand Climate Science Coalition
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. Continue Reading →
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. Continue Reading →
Lord Turnbull, former Cabinet Secretary and head of the Civil Service from 2002 to 2005.
From the GWPF come these remarks by Lord Turnbull to the House of Lords on January 12th, two days ago.
House of Lords: That this House takes note of the Government’s green agenda: My Lords, in a short debate, I will concentrate my remarks on one issue only, the governance of the science, as this is vital for the credibility of the thinking upon which the Government’s policies are based.
In a debate in December 2009 on a report by the Committee on Climate Change, I said:
“Below the surface there are serious questions about the foundations on which it has been constructed”.—[Official Report, 8/12/09; col. 1051.]
Over the subsequent two years my concerns have increased rather than been assuaged.
This is an adopted article.
The governing narrative for our climate change framework can be summarised as follows. Continue Reading →
There has been no significant global surface warming this century, yet experts say that temperatures rose during the first decade, becoming seriously hot. Hotter than ever before, in fact. For example:
The decade ending in 2009 was the warmest on record, new surface temperature figures released Thursday by the National Aeronautics and Space Administration show.
The agency also found that 2009 was the second warmest year since 1880, when modern temperature measurement began. The warmest year was 2005. The other hottest recorded years have all occurred since 1998, NASA said.
James E. Hansen, director of NASA’s Goddard Institute for Space Studies, said that global temperatures varied because of changes in ocean heating and cooling cycles. “When we average temperature over 5 or 10 years to minimize that variability,” said Dr. Hansen, one of the world’s leading climatologists, “we find global warming is continuing unabated.”
But the only thing continuing “unabated” is the linear trend line — it’s still going up, and its slope hasn’t changed. “It’s all right. Only the data show a decline.” Continue Reading →
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. Continue Reading →
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.
I’m sick of all these claims that we should, or even can, limit the world’s warming to 2 °C.
Here’s a challenge: name a scientist prepared to make this assertion and describe the evidence for it.
It appears to be no more “settled science” than an unsubstantiated urban myth. At the very least, there’s so much uncertainty about the climate sensitivity to warming that we don’t know the effect on temperature of, say, 5 billion tonnes of CO2.
Ignoring for a moment the obvious question of what’s so wrong with two degrees, how do “scientists” reason their way from 2 degrees of warming to (as it says below) 44 billion tons of CO2 in 2020? Continue Reading →
Scientists have long debated the impact on global climate of water evaporated from vegetation. New research from Carnegie’s Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere. These findings, published on 14 September in Environmental Research Letters, have major implications for land-use decision making.
The researchers even thought it was possible that evaporation could have a warming effect on global climate, because water vapour acts as a greenhouse gas in the atmosphere.
Using a climate model, they found that increased evaporation actually had an overall cooling effect on the global climate. Continue Reading →
To defeat relativity one did not need the word of 100 scientists, just one fact.
– Albert Einstein.
This statement is not true because Einstein made it — it’s true because it accords with reason. Theory must always bow to observation.
… or just one paper
Unfortunately, in CAGW (catastrophic anthropogenic global warming) we have a theory which is undefined in a peer-reviewed paper, which means it’s almost impossible to refute. This is deliberate. Sceptical questions provoke the inevitable challenge to “produce a better theory” — as though their opponents’ failure to do so proves the half-baked theory correct, which it cannot.
Any evidence contrary to part of the theory is answered by talking about some other part. “Heads we win, tails you lose.”
Any change in the climate, especially any violent weather event which injures us or damages our property, “proves” climate change, which, by a mere trick of linguistic association, “proves” global warming. That, in turn, is our fault. After all, so many people wouldn’t be talking about how to prevent it if it didn’t exist, right?
Everyone claims the right to free speech, but not necessarily for ‘others’. All talk of curbing free speech is for ‘other’ people, never for oneself.
What is a debate? It’s just a few people talking to each other. Who could be afraid of a little debate? Well, when vested interests are concerned, any number of people.
Andy mentions in comments that readers at Hot Topic are talking about emailing PRINZ to stop the climate debate with Christopher Monckton. They say the debate is “unethical” because it spreads confusion.
They complain about Monckton’s use of the phrase “Hitler Youth”. He used this at Copenhagen when a group of youth activists tried to shut down his debate.
Doesn’t anyone do irony any more?
Ironic indeed, but it’s a sinister trend. We live in a free country. We champion free speech everywhere. We were leading activists for freedom from apartheid in South Africa. Now look what’s happening to us. Continue Reading →
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.
A visit from the incomparable Monckton was suddenly proposed and he’s already on his way. There’s nothing like hearing your own community mentioned by the famous, so here’s hoping he finds local matters to comment on and to make our leaders respond. People like Key, Smith and the honchos at NIWA have been simply avoiding our sceptical questions, which makes it impossible to hold their feet to the fire.
I wanted to attend both the Northern Club lunch and the debate at AUT but I will only get to the evening debate.
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? Continue Reading →
Dr Don Brash, leader of the ACT Party. More sense in his little finger than some climate deniers have in their whole body.
But Brash simply reflects reality
A post today at Hot Topic gets really stuck in to Don Brash. Don gave a speech today to the Federated Farmers annual conference. He mentioned the ETS, which exists because of a belief in the dangerous global warming created by the actions of humanity, which Don and many others disbelieve.
Therefore Gareth Renowden, the dynamic self-starter who runs the Hot Topic blog (named after the book he wrote — guess what that’s about?), which exists to sell more copies of his book, so he’s never going to admit he’s wrong about the climate (yes, he has a strong vested interest in this “discussion”), couldn’t let it go without having his say. Thing is, he vilifies more than he informs.
Don wondered aloud (in his speech to the farmers) why we have an ETS. He had to admit (answering himself) that he knows of no good reason at all. I agree we’ve been given no good reason. Continue Reading →

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. Continue Reading →
Professor Keith Hunter didn’t continue his conversation with us here (which we all felt was proceeding very well). He based that decision on unspecified comments from some of our readers. But he’s not above visiting Hot Topic and throwing us a barb from there.
He had this to say a few days ago:
With regard to Treadgold and his ilk, I have to say that there is nothing they say that I can relate to, as an active scientist who works in the climate change arena and who speaks on behalf of many others down here at Otago in that arena. I have told Richard this. For better or worse, my view is that they (RT and co) do not speak for the genuinely skeptic community.
The time for their brand of skepticism is past, I am afraid.
How strange. He’s identified in us a unique brand of scepticism. It must be the brand which won’t go away until evidence turns up. But instead of waxing psychological and talking about scepticism, he should listen to what we’re asking. It’s not very hard.
I cannot imagine Keith’s flexible, wide-ranging intellect being unable to “relate” to the following, because it’s just not difficult to understand! Let me say it slowly:
Jo Nova created this iconic cartoon of the shaky evidence for CAGW.
This is in response (slightly delayed by an Easter break) to the list of “proofs” produced by Gareth Renowden, at Hot Topic, in answer to my request of Sir Peter Gluckman, the PM’s scientific advisor, for evidence of a human cause for anticipated dangerous climate change, more properly referred to as the catastrophic anthropogenic global warming (CAGW) theory.
I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. We have been looking for evidence to show:
1. The existence of a current unprecedented global warming trend.
2. That the greenhouse effect is powerful enough to endanger the environment.
3. A causal link between human activities and dangerously high global temperatures.
4. That climate models have a high level of skill in predicting the climate.
5. A causal link between atmospheric levels of carbon dioxide and global temperatures.
6. A causal link between global warming and the gentle rise in sea level.
In response to this, Gareth claims “there is plenty of evidence to address every one of his points” and presents some attractive and interesting graphics in support. I’ll comment on what he says to each point.
1. The existence of a current unprecedented global warming trend.
Sir Peter Gluckman wants to see the evidence. So do we.
How quickly the climate debate changes
From the Office of the Prime Minister’s Science Advisory Committee comes an announcement with the heading:
Release of an important report on the relationship between evidence and policy formation
One of the key challenges for all governments is how to make the best use of evidence in both policy formation and policy evaluation.
It’s reassuring to hear that the PM’s science advisor is prepared to look for evidence. At least in relation to global warming, it’s not an instinct he’s been noted for. He tells us he’s released a report, Towards better use of evidence in policy formation, and I’d like to read it.
Until I do, I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. Continue Reading →

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
– by Judith Curry. Posted on April 7, 2011
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. Continue Reading →
His response is to claim we made a big error. However, without realising it, Perrott actually accuses Dr Jim Salinger and NIWA itself of that error, because we just copied what Salinger did; what NIWA still does.
Most of Ken’s article at Open Parachute is pious ad hominem nonsense. There’s no reason to respond to all the arm-waving, so the sole point at issue is how to present an annual series with missing data.
The purpose of AWFWY was to compare the NIWA-adjusted Seven-station Series (7SS) with the unadjusted data. It was therefore necessary to use the same techniques as NIWA, insofar as they had been disclosed or were discernible. We had Salinger’s spreadsheet of adjusted readings, and we just did what Salinger did — he averaged years with missing data according to the number of available stations. Exactly what Perrott complains about.
It has come to my attention that you published a (further) letter from a Dr Doug Campbell, again challenging Professor Chris de Freitas’ recent article about the science of global warming. Dr Campbell said: “The facts support anthropogenic global warming with a doubling of atmospheric carbon dioxide resulting in warming of between 2 °C and 4.5 °C.”
I wish to point out that, as a matter of fact, that is not a fact.
Dr de Freitas was talking about an expected temperature increase from carbon dioxide alone of about 1 °C, and he mentioned that was, “by itself, relatively small” and “not controversial.”
Dr Campbell, if he disagrees with that, should cite his authority for doing so. The only source of temperature increases greater than one degree is various computer climate models. These models give different results on each run. Continue Reading →
How do we know there’s a scientific consensus on climate change? Pundits and the press tell us so. And how do the pundits and the press know? Until recently, they typically pointed to the number 2,500 — that’s the number of scientists associated with the United Nations Intergovernmental Panel on Climate Change. Those 2,500, the pundits and the press believed, had endorsed the IPCC position.
From the pen of Chris de Freitas comes this short but compelling narrative, inspired and inspiring, and calming, like a cool balm on an inflammation. Read it and watch the heat from the global warming debate dissipate and important issues clarify. Reprinted here with Chris’ kind permission.
Chris de Freitas: Emotion clouding underlying science of global warming

Unlike most other hot-button environmental issues, global warming is widely misunderstood. As a climate scientist, thinking about this, it struck me that it was not surprising, since accounts of the scientific basics of global warming almost never appear anywhere in the press.
There is not space here to include all the charts and numbers that might accompany such an account. In their place is a necessarily brief summary.
Most people are not shocked to learn that global warming discussions evoke polarised views, but many are surprised to discover that the scientific basics are not contentious. An awareness of these is helpful in building an understanding of the extent to which there is a problem and how it might be addressed. Continue Reading →
