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 [...]

Compulsive namecallers: nutter, conspiracy theorist, anti-semitic, denier — trying to censor through denigration

Got no evidence? Can’t hold a rational discussion? Just call people names — smear them.

David Evans (my other half) pointed out that anyone who opposed the regulating class gets called a racist sooner or later (see those quotes at the end). Now it’s happened to him. Two weeks after getting a mention of climate “feedbacks” into The Age, he’s being called antisemitic. And on what basis? Wait for it… two years ago, on a different topic, Dr David Evans wrote the word “Rothschilds”. Then those who can’t think, but were keen to do a character assassination, leapt to use their psychic abilities, crack secret codes, and drew on their best kindergarten reasoning to call that “antisemitic”. The essay was about banking history and systematic flaws in our currency system, and there was no mention of any religion or any race. But no matter, it’s just another variation of the pathetic Holocaust denier meme. It’s what a smear-artist does — denigrate speakers to try to stop people hearing their message.

As usual, a lack of evidence doesn’t stop the rabid conspiracy-theory-spotters from writing reams of speculation about something that isn’t there and never was.  David has never mentioned anything about [...]

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 [...]

The end of the Global Warming Scare would look a lot like this

Soon, the moment will come when the crowd will say “I always knew it was fake”.

Here are three signs we are at the beginning of The End.

1. Op-Ed writers will be pointing out how governments are unwinding  policies: Dominic Lawson: Britain Has Finally Rejected The Bogus Economics Of Climate Change. Germany (home of half the worlds solar energy production)  is winding up its pursuit of renewables, and eight Eastern European nations said “No Thanks” (legally) to the EU’s authoritarian dictat on carbon emissions, and hardly anyone complained…

And which energy source is ecologically correct Germany now developing faster than any other? Lignite, otherwise known as brown coal, the most carbon- intensive fuel known to modern man.

This makes the countries on the European Union’s eastern borders (notably Poland, for which indigenous coal is a dominant energy source) even more reluctant to accept the national emissions targets promoted by Brussels. Eight of these nations launched a legal challenge and last week they won a ruling by the European Court of Justice that Brussels had exceeded its powers in imposing such limits. The court brushed aside the European commission’s complaint that it would not otherwise be [...]

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 [...]

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 [...]

This is not journalism, Wendy Carlisle

Background Briefing ABC Radio National July 17th

I’m sure Wendy Carlisle thinks she’s helping Australia.

The awarded writer who calls herself a science journalist, breaks laws of reason, makes a litany of careless errors, ambushes interviewees with false claims, and devoutly stares past hundreds of peer reviewed references as if they don’t exist. Yes, Anything but the evidence!

She thinks hunting through resumes of retired scientists is a good way to inform us about the need for a Carbon (sic) Tax.

It’s a wake up call ladies and gentlemen. This is the state of “science” at your ABC where polite discussion and meaningful research has been replaced with tabloid guttertalk.

The ABC is not part of the problem, it IS the problem. It’s not just that we spent $1 billion last year on the ABC — the real cost of the propaganda-machine disguised as “impartial reporting” is the billions of dollars we have already malinvested due to the ABC’s inability to provide rigorous and relevant science reporting, and the multi-billions more we are about to waste.

The nation is about to undergo a [...]

Climate Commission Report Debunked

Scientific audit of the Climate Commission Report “The Critical Decade – Climate science, risks and responses”

May, 2011

Bob Carter, David Evans, Stewart Franks, William Kininmonth

PART I – INTRODUCTION, DISCUSSION & CONCLUSIONS

For PART II – SCIENCE AUDIT see the Full PDF file of Part I & II

Also posted at Quadrant Online, May 30, 2011

INTRODUCTION

The Key Messages[1] summary of The Critical Decade[2] opens with a ringing statement of hyperbole:

Over many decades thousands of scientists have painted an unambiguous picture: the global climate is changing and humanity is almost surely the primary cause. The risks have never been clearer and the case for action has never been more urgent.

This declaration establishes two things. The first sentence signals that the report is committed to repeating the conclusions of the 4th Assessment Report of the UN’s Intergovernmental Panel of Climate Change (IPCC)[3], conclusions that are essentially reliant on computer modelling and lack empirical support. And the second signals that the report is long on opinionated analysis and political advocacy but devoid of objective risk analysis.

These same characteristics apply to the scientific [...]
