Buy gold while it’s in the ground (Plus David and Jo will be in Sydney at the Gold Symposium – Monday)

UPDATED (Already) Money is grubby thing, but financial independence means freedom. Freedom to spend time writing what a heart believes instead of what an employer demands. (Freedom to follow the most inexplicable whim — like tossing the 9-5 day to debate details of dendroclimatology with people who detest you). I wouldn’t be able to indulge in the luxury of writing this blog if it weren’t for the gold shares that keep food on the table. Next Monday David is speaking at The Gold Symposium in Sydney. (I’ll be in the audience.) Who should go? — only people who don’t want to be poor. I want to see both these independent conferences succeed (The AEF too), I want to share the word about both money and science, and I want to help independent spirits meet up. That’s why I’m giving them both a shameless plug before the article. There is a big overlap between gold and skepticism: skeptical of government science often means skeptical of government money too (see We are all Austrians now). For the pure-science readers here, it may all seem thoroughly odd, but while some will paint gold as a fatuous symbol of pointless wealth – and sometimes [...]

David Evans in the Fairfax press: Climate change science is a load of hot air and warmists are wrong

Today in the Sydney Morning Herald and The Age, for the first time, David Evans has been published in the Op-Ed section. Something is going on in those newsrooms…? This article, below, simply makes the point that the models amplify the direct effect of CO2 by a factor of three and that is where the most important uncertainties lie. This key factor in the debate — which we cover repeatedly on this blog– has virtually never been made before in these newspapers which are the major dailies for Australia’s two largest cities. Any debate about the effects of CO2 needs to start with the fact that most of the warming in the models comes from amplification of humidity and clouds. If the models were right about water vapor, we would have found that missing hot spot. – Jo PS: The SMH and The AGE have both closed comments already! Have they run out of electrons? Oh my? Or were they afraid the comments looked like a debate?

UPDATE: I’ve just posted that these major dailies have “disappeared” the Muller conversion article too!

David Evans explains the skeptics case (YouTube)

Last week we finished some YouTube versions explaining the skeptical case. These grew out of the interview we did with Nick Minchin and Anna Rose for the ABC documentary I Can Change Your Mind. They are what we would have said, if we’d been editing the documentary .

In the interview we were on a mission to show the evidence the ABC won’t show — and of course, true to form, the ABC did exactly that, and didn’t show it. As David often points out, the mainstream media have never shown this data anywhere in the world, ever, even though it is extremely relevant, from mankind’s best and latest instruments, from impeccable sources, and is publicly available. Not to mention that billions of dollars of public policies depend on getting this right either.

This is a strictly no-budget approach to organize the message for those on the web who prefer to see video’s rather than read papers. Here are three YouTube’s by David Evans, thanks to Barry Corke (for the filming and editing). I hear that one I did will be ready sometime.

A little background. When the documentary interview happened in our kitchen, we noticed something interesting. We felt [...]

Climate Coup — The Politics

How the regulating class is using bogus claims

about climate change to entrench and extend their

economic privileges and political control.

The Science

The sister article Climate Coup—The Science (a more mainstream version of The Skeptic’s Case) contains the science foundation for this essay. It checks the track record of the climate models against our best and latest data, from impeccable sources. It details how you can download this data yourself. It finds that the climate models got all their major predictions wrong:

Test Climate Models Air temperatures from 1988 Actual rise was less than the rise predicted for drastic cuts in CO2 Air temperatures from 1990 Over-estimated trend rise Ocean temperatures from 2003 Over-estimated trend rise greatly Atmospheric hotspot Completely missing –> water vapor feedback not amplifying Outgoing radiation Opposite to reality –> water vapor feedback not amplifying

The latter two items are especially pertinent, because they show that the crucial amplification by water vapor feedback [i] assumed by the models does not exist in reality. Modelers guessed that of the forces on [...]

The Skeptic’s Case Who Are You Going To Believe – The Government Climate Scientists Or The Data? Guest Post Dr David M.W. Evans

We check the main predictions of the climate models against the best and latest data. Fortunately the climate models got all their major predictions wrong. Why? Every serious skeptical scientist has been consistently saying essentially the same thing for over 20 years, yet most people have never heard the message — here it is, put simply enough for any lay reader willing to pay attention.

What the Government Climate Scientists Say

Figure 1: The climate models. If the CO2 level doubles (as it is on course to do by about 2070 to 2100), the climate models estimate the temperature increase due to that extra CO2 will be about 1.1°C × 3 = 3.3°C. [1]

The direct effect of CO2 is well-established physics, based on laboratory results, and known for over a century.[2]

Feedbacks are due to the ways the Earth reacts to the direct warming effect of the CO2. The threefold amplification by feedbacks is based on the [...]

Dr David Evans: Four fatal pieces of evidence

Dr David Evans lays out four crucial pieces of evidence, and calls for a debate with Prof Andrew Pitman. But the evidence is so unarguably strong for skeptics, we know that the name-calling-team-who-want-our-money will do anything to avoid a public debate. If the evidence is “overwhelming” why are they so unwilling to explain it? — Jo

Submission to the Inquiry into Carbon Tax Pricing Mechanisms

Dr David Evans

20 September 2011

Dr David Evans consulted full-time for the Australian Greenhouse Office from 1999 to 2005, and part-time to the Department of Climate Change from 2008 to 2010, modeling Australia’s carbon in plants, debris, mulch, soils, and forestry and agricultural products. Evans is a mathematician and engineer, with six university degrees including a PhD from Stanford University.

Global warming has become a scam. Let me explain how it works.

It has superficial plausibility. Yes, global warming is occurring. Yes, carbon dioxide is a greenhouse gas and levels are rising. And yes, every molecule of carbon dioxide we emit causes some global warming.

Many non-scientists think that proves the case, but it doesn’t. In particular, it doesn’t rule out the possibility that carbon dioxide is merely [...]

Scary Exaggerations Unfounded

GUEST POST: Dr David Evans and Professor Bob Carter

Their Latest Scary Forecast

The latest from the Climate Commission is very, very scary:

[I just love this graph. It's so over-the-top, it's like a "Pepsi-climate" ad -JN]

They reckon we have to stabilize carbon dioxide emissions immediately or we’ll fry. But these forecasts are based solely on what are essentially the same faulty climate models as in 1988, and are similarly exaggerated.

Their Earlier Scary Forecast Was Bunk

U.S. government climate scientists started the climate scare with a forecast to the U.S. Congress in 1988 which was based on climate models. Here it is, with the actual temperature that eventuated later added in red:

David Evans, Carbon Accounting Modeler, Says It’s a Scam

Dr David Evans’ address to the Anti-Carbon-Tax rally, Perth Australia, 23 March 2011.

Good Morning Ladies and Gentlemen.

The debate about global warming has reached ridiculous proportions and is full of micro thin half-truths and misunderstandings. I am a scientist who was on the carbon gravy train, understands the evidence, was once an alarmist, but am now a skeptic. Watching this issue unfold has been amusing but, lately, worrying. This issue is tearing society apart, making fools and liars out of our politicians.

Let’s set a few things straight.

The whole idea that carbon dioxide is the main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s. But the gravy train was too big, with too many jobs, industries, trading profits, political careers, and the possibility of world government and total control riding on the outcome. So rather than admit they were wrong, the governments, and their tame climate scientists, now cheat and lie outrageously to maintain the fiction that carbon dioxide is a dangerous pollutant.

Let’s be perfectly clear. Carbon dioxide is a greenhouse gas, and other things being equal, the more carbon dioxide in [...]

Is the Western Climate Establishment Corrupt? Part 10: Gore Orwell

The public might not understand the science, but they do understand cheating

Dr. David Evans 19 October 2010

[A series of articles reviewing the western climate establishment and the media. The first and second discussed air temperatures, the third was on ocean temperatures, and fourth discussed past temperatures, the fifth compared the alleged cause (human CO2 emissions) with the alleged effect (temperatures), the sixth canvassed the infamous attempt to “fix” that disconnect, the hockey stick, and the seventh pointed out that the Chinese, Russian, and Indian climate establishments (which are financially independent of the western climate establishment) disagree with the western climate establishment about the cause of recent global warming and the eighth showed how government institutional and funding pressures created the consensus among western climate scientists. The ninth showed the evidence that the amplifying feedbacks, responsible for two-thirds of the model warming projections, are not present in reality—and that the lame response of the establishment was to miscolour a graph to mislead us into thinking those feedbacks were [...]

This point is THE critical one. It was the first point raised in the Skeptics Handbook, developed in the Second Handbook; the point that Dr Glikson had no reply to; the point that tripped up Will Steffen, Deltoid, and John Cook. As a modeler there was the moment in August 2007 when David saw the graphs below and said, emphatically: This is it. It’s over for the climate models. –JN

The western climate establishment consists of the climate science research bodies in the western world, and their climate scientists. The leading organizations are the IPCC of the United Nations, the CRU in Britain, and GISS and NOAA in the United States. Personnel move around within the establishment, getting funding from the same sources, collaborating on projects, and publishing in the same journals.

There are other climate establishments in this world, and [...]

Is the Western Climate Establishment Corrupt? Part 6: The Hockey Stick

I know the Hockey Stick is old news to most blog readers here, but it’s easy to forget that the people reading the mainstream news (ie: most of the West) have no idea of the scale of the audacity involved. Up until the 1998 MBH paper came out, it was widely understood that there was a Medieval Warm Period, indeed there were hundreds of papers available at the time. The Hockey Stick Graph completely rewrote everything, yet was accepted and widely promoted without anyone so much as asking for the data… until, of course, McIntyre and McKitrick tried. It will do down in the annuals of science as one of the most egregious examples of “the not-so-scientific” method. — JoNova

Notice How They Never Directly Compare Temperature With Human Emissions of CO2?

According to the man-made theory of global warming promoted by the western climate establishment, the recent global warming is due to human emissions of greenhouse gases, which are dominated by carbon dioxide (CO2).

So let’s compare the alleged cause (human emissions of CO2) with the alleged effect (temperature).

Human emissions of CO2 have been estimated from historical data for the period 1751 (before the industrial revolution) to 2007 for the major sources—coal, gas, and petroleum use, cement production, and gas flaring—by the Carbon Dioxide Information Analysis Center within the US Department of Energy. (The cumulative figures below extrapolate to 2010 using average annual emissions for the previous 14 years.)

They Don’t Tell You: The Current Global Warming Trend is Over 300 Years Old

A Scene on the Ice by Hendrick Avercamp, circa 1600

Satellite data only goes back to 1979, and global land-thermometer records only go back to 1850. Before that we have to resort to “proxies”, which are various natural phenomena from which temperature can be deduced. As we go further back in time, the errors and uncertainties increase.

Is the Western Climate Establishment Corrupt? Part 3

There are two strong points here:

The Argo system is state of the art, and public property. Yet the most recent Argo Data of ocean temperatures is virtually impossible to get. We could assume that if it showed definitive warming, we’d see those graphs on breakfast cereal packages. Ocean temperatures trump everything. Where is that warming? The same people who are paid to analyze the data sets are the ones who also manage them: they decide who has access. It’s a system without external independent checks, and the lack of audits makes for a loophole big enough to drive a planetary body though. — JN Part 3: Ocean Temperatures

Is the Western Climate Establishment Corrupt? Part 2

…

The establishment barks “cherry-picking” at skeptics who claim a particular year was cold, or quiet, or less stormy, but where are the caveats when the mass media churns out record single “hot year” headlines as if they matter: 2010 is hottest year EVER!

What’s not obvious is that breaking those records depends on the data set. According to satellite data there have been no “hottest year ever” records since 1998, though as it happens, NASA doesn’t seem too keen on using data recorded from space. Go figure.

With ground stations, every single station requires hand-made “adjustments” and many stations are ignored completely. The results from ground stations are “interpreted” to cover anything from zero kilometers right up to 1200 km. I guess, only a God of Science would know which thermometer has that magic-1200-gift. Meanwhile, the satellite records are a massive collection of data recorded continuously 24/7, year after year and covering all round the globe, land and sea.

Part II of this series is about those “adjustments” and the different data sets.

Is the Western Climate Establishment Corrupt? Part I

For months now, behind the scenes, David and I have discussed just how powerful questions can be. Sometimes it’s not what you know, but what you ask that makes the most powerful point.

For his Heartland presentation last Friday, David delivered a themed compilation of example after example of the Western Climate Establishment allowing mistakes, errors or biases to accumulate — each factor on it’s own might be hard to pin down, but the sum total of actions (and inactions) forms a wholly consistent pattern.

This is Part I. These photos speak for themselves, but as far as I know, they haven’t been assembled in one web page before and David stopped waiting for me to get the time to annotate them and has helpfully used red arrows so even the less technically minded will “get” the implications.

You don’t need to have a PhD to know that the thermometers used to measure global warming are not placed well. There are at least Two Great Burning Questions here:

Burning Question 1:

NOAA is a $4 billion dollar agency. If they were determined to get the most accurate, reliable measurements possible would they leave so many sensors [...]

The future of climate alarmism is bogus statistics

Dr David Evans and Joanne Nova

The temptation is all too strong. How many bureaucrats would work just as hard to show that their department was less important, less necessary, and less deserving of funding? It’s the fatal trap of socialist management. The incentives are wrong.

When governments are faced with poor reports, but they write their own report cards, they have many options to upgrade their “score”. It’s insane to think that people might not take every opportunity they can to improve their mark. They are human.

Big problems like inflation, unemployment, national growth, or global temperatures can be “improved” two ways –one way takes tough decisions and years of work, and the other way takes a quiet statistical summit, a white paper and an in-house training weekend. It’s easier to “solve” big problems by changing the way you measure them. By changing definitions, methods of interpreting the data, or through sheer statistical chicanery it’s possible to issue press releases with the words “improvement”, “better than expected” or at least “figures have plateaued”.

Ocean temperatures: the new bluff in alarmism

There has been a change in direction by the alarmists, as shown by their new “Synthesis Report.” The independent scientists noticed it during the Wong-Fielding meeting.

The alarmists have abandoned air temperatures as a measure of global temperature, because the air temperature graphs are just too hard to argue with (like the second figure below, from the Skeptics Handbook). Instead they’ve switched to ocean temperatures, which they often disguise as ocean heat content (a huge number like 15×10²² Joules sounds much more scary than the warming it implies of 0.003° C/year).

All three pages of the Synthesis Report that deal with ‘evidence’ are about factors or trends that tell us nothing about whether or not the warming is due to carbon emissions. If God put the galaxy in a toaster, sea levels would rise, ocean heat content would increase, and ice would melt.

Notice how the graph above from the Synthesis Report that came out this month doesn’t include the last six years of data? Carrier pigeons from the remote worldwide network of Argo buoys make it back to base eventually, but the world’s leading team of climate researchers seem to have trouble googling “argo”. Not coincidentally, measurements [...]
