Tyrants always want to silence the critics

Plus ca change, plus c’est la meme chose.

Two hundred and fifty years ago the pamphleteers were the bloggers of the day. The Finkelstein plan in Australia is a modern version of the License of the Press under George III. Another excuse to tell people what they are allowed to read.

One John Wilkes was elected MP for Aylesbury in 1757.  George III soon-to-be-crowned King, arranged for his friend the Earl of Bute to get the job of PM. Wilkes wasn’t too happy with that. He thought Bute was incompetent, and so when one supporter of Bute started a newsletter called The Briton, it was only eight days later that Wilkes started his own newsletter, called the North Briton in response. Wilkes wrote anonymously each week, but his 45th edition was too much for George III and Wilkes was charged with Libel for accusing the George of lying, and he was tossed in the Tower. He challenged the arrest and won (eventually). His speeches during the trial became famous and had people chanting “liberty and Wilkes” in the streets. Sadly troops fired on the protesters, killing seven, in the Massacre of St George’s Field. The cry of “45″ (from the [...]

Bingo! We’re back… :-)

There are many details to iron out, but thanks to some pesky hacks, I now have a bigger support team, a larger network of shared expertise, a much larger server and eventually, as we work through the site, a more efficient, faster site, that is more resilient, more stable, with a better back up system. I’ve also had a few very helpful donations.

We’re not protected by a soft media, a large public purse, and we don’t hide behind a censored fake debate as so many do.

They can attack, but it only makes us stronger.

More soon…

 

Please report things you notice here that need a fix.

We are aware of the thumbs up, and a few missing image links. Tell us how the service works for you.

The Temporary site is still up, and may stay there indefinitely. So  if you had a comment or conversation there: Not there yet, Still not there yet,  I needed a holiday and  “Sunny Days” . Thanks for your patience.

Massive Eltanin Meteor 2.5 million years ago set off mass tsunami, changed the climate?

From the file of “Things that would really be catastrophic”. Did a meteor have a role in a major shift in Earth’s Climate?

The start of the Quaternary period (2.588 million years ago, where the Pliocene became Pleistocene) coincides with evidence of a mega tsunami in the South Pacific.

The Eltanin Meteor fell into the South Pacific 2.5 million years ago setting off a (likely) tsunami that was hundreds of meters high and theoretically pushed mass material into the atmosphere which may have contributed to the cooling the globe had already started on. This meteor was hard to detect because it hit the ocean rather than the land. But researchers have pieced together evidence of the mass tsunami on continents around the pacific rim.

Figure 1. Possible effects of the Eltanin megatsunami. (A) Composite model of wave amplitudes for the South Pacific [modified after Ward and Asphaug (2002) but with a greater decay rate of wave amplitude away from the impact point; this produces lower wave amplitudes on affected coasts, more in line with recent findings but not as low as those proposed by Shuvalov and Trubetskaya (2007)]: ANT, Antarctica; AU, Australia; NZ, New Zealand; SA, South America.

McIntyre v Lewandowsky — Can we call in a statistician at UWA to help Lew?

The Lewandowsky view is Drilling into noise. The McIntyre response: Lewandowsky’s Fake Correlation

My favourite Lewandowsky line is: “We cannot get into the details here…”

McIntyre can and does in gory depth. He posts the equations, the code, the tables, everything. He graphs the residuals, and shows the “severe non-normality” of them. He tests the correlation and finds that the two most obvious fake responses heavily affect the results:

“Lewandowsky is absolutely off-base in his assertion that the examination of outliers is inappropriate statistical analysis. In fact, exactly the opposite is the case: proper statistical analysis REQUIRES the examination of outliers.”

“One can readily see that the two super-scammers (889, 963) contribute essentially 100% (over 100%) actually of the negative correlation between CauseHIV and CYMoon in this calculation.”

Lewandowsky says: “no one who has toyed with our data has thus far exhibited any knowledge of the crucial notion of a latent construct or latent variable.”

McIntyre replies: “Principal components, a frequent topic at this blog, are a form of latent variable analysis.”

As a former graduate of UWA, this is embarrassing. Does UWA not teach and use rigorous statistical methods? Is there no one who can help him?

Antarctic sea ice trends at record highs. Fears for shrinking southern ocean, right?

While stories of the Arctic record fall in sea-ice have been all over the news, all over the world, it’s almost as if the Southern Hemisphere didn’t exist. Right now, this week apparently, the sea ice is at or near record highs (bearing in mind that we’re still only talking 30 years of satellite records, but then, these are the same satellites lapping over the arctic, and if the records are longer there, I expect it’s only by an hour and a half).

 

h/t Steve Goddard who asks when the National Snow & Ice Data Centre ( NSIDC) will send out the press releases. They appear to be more concerned about the effects of the Antarctic “thinning” trend on penguins this week. Sunshine hours has graphed it in detail.

Cryosphere compares the relentless fall and rise of Antarctic ice here. Millions of square kilometers in staggering, dramatic melts every spring manage to return in staggering dramatic ice formations each and every year.

I expect that our non-hemispherist unbiased and diligent newspapers will be running with matching ones very soon. Based on news stories like this:

Lewandowksy, Oberauer, Gignac – Is the paper bad enough to make history?

Stephan Lewandowsky, Gilles Gignac, Klaus Oberauer

The scathing blog posts are popping up everywhere. From William Briggs we get a sense of the historical importance of the Lewandowsky et al effort. One day a terrific psychological study is going to be written on the madness and mass lunacy which arose after climate change swam into the public’s ken… The cornerstone of this future pathological report may well be the peer-reviewed Psychological Science paper “NASA faked the moon landing—Therefore (Climate) Science is a Hoax: An Anatomy of the Motivated Rejection of Science” by Stephan Lewandowsky, Klaus Oberauer, and Gilles Gignac, perhaps the completest, most representative work of its odd era. “Everything that could have been done wrong, was done wrong. Every bias that could have been manifested, was manifested. Every fallacy pertinent to the matter at hand was made. The conclusions, regurgitated from unnecessarily complicated statistical procedures, did not follow from the evidence gathered, which itself was suspect. In its way, then, the paper is a jewel, a gift to the future, a fundamental text to how easy it is to fool oneself. “ Steve McIntyre goes through the statistical tests, finds questionable practices, questions he can’t answer, and general [...]

Government burn $70 billion a year subsidizing renewables, and wild claims of “fossil fuel subsidies” debunked

When activists protest about “fossil fuel” subsidies, it is a case of extreme-wordsmithing. Like chinese-whispers, the truth gets turned 180 degrees. It takes a string of half truths stacked in a series to come up with something which is so completely counter to reality it is meaningless.

The reality is that governments around the world are paying billions each year to prop up an industry that is inefficient, uncompetitive and unproductive. It’s money that is desperately needed in health or in real medical and scientific research.

“More than US$70 billion of support is provided by governments to renewable energy production and consumption worldwide.”

[IEA (The International Energy Agency, which promotes "green energy" in it's header)]

That’s an annual figure. And the plan seems to be even more subsidies. (I thought the plan was to make renewables competitive?)

Global Carbon Trading System Has “Essentially Collapsed”

When is a free market not free? When it doesn’t do what the bureaucrats wanted it to “freely do”. There is a message from this-pale-shadow-of-a-global-carbon-free-market and it’s telling us that carbon (dioxide) should be free, as in $0, no cost, no fee, no tax.

CDM’s (Clean Development Mechanisms) were set up in 1997 with Kyoto. It is separate from the EU market, and is one of the only “global” carbon markets.

 

Global carbon trading system has ‘essentially collapsed’

The UN clean development mechanism, designed to give poor countries access to green technologies, is in dire need of rescue

Fiona Harvey, environment correspondent

The world’s only global system of carbon trading, designed to give poor countries access to new green technologies, has “essentially collapsed”, jeopardising future flows of finance to the developing world.

Billions of dollars have been raised in the past seven years through the United Nations‘ system to set up greenhouse gas-cutting projects, such as windfarms and solar panels, in poor nations. But the failure of governments to provide firm guarantees to continue with the system beyond this year has raised serious concerns over whether it can survive.

Lewandowsky gets $1.7m of taxpayer funds to denigrate people who disagree with him

Stephan Lewandowsky, Gilles Gignac, Klaus Oberauer

Stephen Lewandowsky’s paper, soon to be published in Psychological Science, appears to be drawn from one or two grants from the Australian Research Council that total nearly a million dollars (though it’s not entirely clear which grants apply to the paper).

“If you wonder, like I do, whether the Australian taxpayer gets value for money, ponder that somewhere a cancer researcher was denied funding in order for Lewandowsky to do his work”

One grant, which he shares with coauthor Dr Klaus Oberauer, was for $694,000 for research on “Keeping Memory Current: Updating and Discounting of Information“. Apparently it is of national benefit, because: “Basic research in psychology is of particular national benefit because the available national research funding is commensurate with the requirements of world-class research in psychology.” “World class” does not usually mean research based on a logical error with a sample too small to be statistically significant and using a self-selecting, unsecure, sample from sites that detest the research group. Aside from that, the sentence itself is circular bureaucratese-babble. What does it mean? Is he suggesting that research in basic psychology is useful because taxpayer funds are only given to world class [...]

Climate Models: 100% right except for rain, drought, storms, humidity and everything else

Yet more observations from the planet show that modelers misunderstand the water based part of the climate – on our water based planet.

Modelers thought that dry ground would decrease afternoon storms and rainfall over those frazzled parched lands (though I don’t remember many headlines predicting “More Drought means Fewer Storms” ). But observations show that storms are more likely to rain over dry soil. Why? Probably the dry soil heats up faster than moist areas thanks to the cooling effect of evaporation, and that in turn creates stronger thermals over dry land. Modelers assumed that wetter soils means more evaporation and thus more rain, but the moisture laden air is evidently coming from further away.

It’s another example of a point where climate modelers assume a positive feedback, yet the evidence suggests the feedback is negative. Once again water appears to be the dominant force with feedbacks (it does cover 70% of the surface). In a natural stable system the net feedbacks are likely to be negative. Positive feedbacks make the system less stable (and more scary and harder to predict.)
