It’s hard to measure sea levels, because land often moves up and down too (which is known as “isostatic“). But Australia is stable tectonically, so the Australian sea-level record is more useful than most. It preserves the holocene era and the rises and falls, and correspond more with glacio-eustatic (ice equivalent) sea-level changes, rather than changes in land masses.
During the coldest days of the last ice age (known as a glacial maximum) 20,000 years ago, the oceans were 125m lower than today. They peaked at around 1 -2 meters higher than present between 9000 and 5000 years ago, and have been trending down ever since. Our current rate of 30cm/century (if that continues) hardly seems unprecedented or highly unusual. And 10% of that is apparently due to an isostatic “adjustment”. Worse, if you look at the raw data, the rate is closer to zero. Hmm. Lucky we have all those adjustments eh?
If Australian sea levels keep falling at this rate, we might really need to save That Reef.
Clearly there are many details yet to be worked out about sea-levels.
That phenomenal rise out of the ice age:

Follow the money. As usual the Green trail ends at a Greenback (so-to-speak). In this case it’s the euro-colored kind. The EU is focusing on “first generation” biofuels — corn, soy, sugar and palm oil — which pushes up prices of food, and cuts down forests. (In a recent study, sugar cane ethanol was shown to produce 10 times the pollution of gasoline and diesel.) In contrast “second generation” biofuels are waste products. If the EU were interested in the environment, they would favour the second type. Instead, the policy hurts the poor and enriches the rich and does little to help the environment.
In 2010, Indur Goklany calculated the additional mortality burden of biofuels policies and found that nearly 200,000 people died in that year alone because of efforts to use biofuels to reduce CO2 emissions.
Where are the Greens protests?

In a move of Olympian audacity, Seth Borenstein keeps a straight face and shamelessly shifts to pretending that more Antarctic sea-ice fits their climate change theory. Yet again climate models fail to predict things in advance, they only do the post modern type of prediction — the bury-my-bewilderment type, after the fact. Once more, nothing can disprove the theory of man-made climate catastrophe.
The oceans are warming, but that now means less sea ice in the Arctic, and more sea-ice in the Antarctic. Of course!
Shifts in wind patterns and the giant ozone hole over the Antarctic this time of year — both related to human activity — are probably behind the increase in ice, experts say. This subtle growth in winter sea ice since scientists began measuring it in 1979 was initially surprising, they say, but makes sense the more it is studied.
The only point of science is to predict things. But when alarmist predictions turn out to be wrong, Borenstein and co don’t adjust the theory, they pretend post hoc that the new results “fitted” all along, and radiate collective amnesia about the hundreds of times they “experts” predicted the opposite.

When everything else about being Green turns out to be a pox on the environment, it’s no surprise that electric cars are too.
The Norwegian University of Science and Technology study found greenhouse gas emissions [of electric cars] rose dramatically if coal was used to produce the electricity.
Electric car factories also emitted more toxic waste than conventional car factories, their report in the Journal of Industrial Ecology said.
So electric cars are only bad if they are powered by coal fired electricity, or made in a factory. Oh.
Presumably the aspiring Green needs a hand-made hydroelectric car, right? That, or the kind of car that has 18 gears, a chain and two wheels.
The kicker with electric vehicles, or EVs, is that awful secret that batteries don’t grow on trees, don’t recharge spontaneously either, and need replacing every five years or so. There is no getting around the fact that electric vehicles need electricity. They may not emit any evil CO2 themselves, but they have to get those electrons from somewhere, and in most places that’s from coal.
And it wasn’t just the coal, it was other stages of the “life-cycle” too. The production of EVs produced about twice […]
At the end of next week, the Australian Environment Foundation is hosting its annual conference. I had such a good time at the last one I attended (in 2009) that I’m going again, this time, not as a speaker, but just to be there. Bob Carter is attending too. This is one of the rare events this year to spend time with passionate rational people in Australia — people who are interested in the outcomes, not just the intentions. Find out the latest developments in protecting the environment with a pragmatic, science-based approach. And it’s not just about the speeches, the conference also includes a Tall Ships Cruise, a Gala Dinner, informal drinks, and an open forum.
The conference covers the science of fisheries, wind farms, water resources, temperature records, indigenous land-management and the economics (from a former reserve bank board member) of the carbon tax.
Costs between $85 – $250 (depending on membership and the events chosen). Details: Word, pdf or PayPal

Some skeptics wonder why I bother pursing and documenting the problems with Lewandowsky et al 2012 and with the blog ShapingTomorrowsWorld. They figure that all skeptics now know the papers dismal failings, and it’s clear that Lewandowsky is unlikely to be grateful for the help.
But Lewandowsky exposes people higher up to awkward questions. Why do they fund work so unscientific? Why do they allow such hypocrisy and bias on a government funded publication? Are standards at the University of Western Australia (UWA) so low that they can’t find a Professor who understands the scientific method, and can reason without name-calling? Aren’t other statisticians at UWA concerned at what Lewandowsky is doing to the reputation of “UWA Statistics”? Finally, aren’t the scientists who missed out on ARC funding angry that our taxpayer funds are given instead to someone who apparently uses the funds to promote his personal political views, instead of in the pursuit of knowledge? (See: Lewandowsky gets $1.7m of taxpayer funds to denigrate people who disagree with him)
The abject incompetence is a gift to us. Rarely is a study so outrageously bad that people with no scientific background […]

We already know that pH varies naturally across the oceans of the world. In some sites, it varies more in a single day than global oceans are likely to face in a century.
But cold water corals live in deep water, are slow growing, and hard to study.
Six years ago, experts in cold water corals were telling us how they would be likely to fall victim to ocean acidification first, and that they believed this for good reasons but with little experimental data. But about a year ago data came out (by one of those same experts) showing that rather than being the badly affected, cold water corals adapted to effectively very high levels of CO2 and possibly even increased their calcification rates. Eight days after the pH was changed suddenly, the corals did worse. But when the experiment was continued for six months, the results turned right around. The researchers pointed out how useful longer studies are: “This is the first evidence of successful acclimation in a coral species to ocean acidification, emphasizing the general need for long-term incubations”. The paper is called “Acclimation to ocean acidification during long-term CO2 exposure […]
Good on you Chris Tangey.
Chris Tangey captured moving images of a dust storm picking up a bushfire.
He’s turned down some income to stand on his principles.
Al Gore wanted to use the awesome shots of a dust devil picking up a bushfire, which happened on Sept 11, 360km southwest of Alice Springs at Curtin Springs Station. When Al Gores office asked for rights to use the footage, Tangey knocked him back. He felt its use in a climate change setting would be “deliberately deceptive” and that it was “difficult for me to imagine a fire event less relevant”.
“I am aware that you may have missed the reporting on the very localised nature of this firestorm,” Tangey wrote. “However, in any case, I am confused as to why you would offer to buy a licence to use it at all unless you had conducted even elementary research which might indicate that this Mt Conner event had direct linkage to global warming/climate change.”

The theory that failed
It takes only one experiment to disprove a theory. The climate models are predicting a global disaster, but the empirical evidence disagrees. The theory of catastrophic man-made global warming has been tested from many independent angles.
The heat is missing from oceans; it’s missing from the upper troposphere. The clouds are not behaving as predicted. The models can’t predict the short term, the regional, or the long term. They don’t predict the past. How could they predict the future?
The models didn’t correctly predict changes in outgoing radiation, or the humidity and temperature trends of the upper troposphere. The single most important fact, dominating everything else, is that the ocean heat content has barely increased since 2003 (and quite possibly decreased) counter to the simulations. In a best case scenario, any increase reported is not enough. Models can’t predict local and regional patterns or seasonal effects, yet modelers add up all the erroneous micro-estimates and claim to produce an accurate macro global forecast. Most of the warming happened in a step change in 1977, […]
Report your site and email troubles here (if you can). I gather some people are getting patchy access, and having trouble emailing me.
We moved the site again last night, and the changes propagate throughout the global network some people appear to be losing access temporarily. As it happens my access is faster than ever — so hopefully yours will be too, soon. (Thank Andrew for that).
Perhaps clear those caches… (yes, that’s a message for all the people who can’t read this ;-)).
Somehow I have about ten articles in draft and none of them quite ready. There is a lot on the boil…

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 […]
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.

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.

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?
Plus, when […]
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).

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 […]
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.

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 […]
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.)
