We are longtime Labor Party members who believe the urban progressive-left has turned its back on ordinary working people: the 70 per cent of the workforce who hold blue-collar and routine white-collar ‘jobs’, as distinct from the 30 per cent who enjoy professional ‘careers’.

While one of us has worked for Labor politicians, and both of us are past or present local branch office-holders, we do not depend on any branch of the labour movement for our living, so we are free to speak our minds. We have diverse private and public sector work histories: currently one of us is a bureaucrat and one a lawyer.

The carbon experiment
Terence Corcoran, Financial Post 
Published: Saturday, May 31, 2008

In any discussion of carbon taxes, no matter what their form, it is important to keep the core economic theory in focus. The basic idea, advanced by early 20th-century economist Arthur C. Pigou, is that if a society wants to reduce the use of something that's undesirable, the best way to do that is to have the government tax it. Pigou is the magician behind the great global pressure from economists and politicians -- from Stephane Dion to Stephen Harper, from John McCain to Nicholas Sarkozy --for taxes on carbon emissions.

The theory is simple enough, and intuitively appealing. In the Pigouvian world, if you raise the price of carbon, the laws of supply and demand will kick in and carbon use--from burning coal, oil, gas, wood-- will fall. As carbon use falls, the threat of man-made global warming will be reduced, maybe even eliminated. Beautifully simple. Who could not like such a clean solution to a messy problem?

Unfortunately, little of what Pigou said on the subject of Pigouvian taxes is of any use to policy makers. How high should the tax be? How do you set targets for measuring effectiveness? What do you do about the side effects of the taxes? What do you do with the tax revenue?

Pigou is silent on all of this, but these are the important carbon tax questions. It ultimately matters not whether governments try to tax carbon directly, right down at the gasoline pump as planned in British Columbia, or whether they try complex "cap-and-trade" schemes that seem to tax big corporate polluters and let the rest of us get off with little direct burden.

Never mind, also, whether a climate change catastrophe looms between now and 2080 or 2120 or 2180 or whenever. The science, a quagmire of uncertainty, is irrelevant to the economics of carbon taxes.

So lets look briefly at our main questions.

How high should the tax be?

With oil at $130 a barrel, we already have in place the equivalent of a carbon tax of about $300 a tonne. The impact of that price increase is rattling through the economy, transferring massive amounts of wealth from consumers to energy producers. But if this new oil price were to persist, would it cut oil-based carbon emissions to the levels we supposedly need to save the planet? Nobody knows, but it's not likely. The B. C. carbon tax, set to reach $30 for each tonne of carbon, will obviously do even less to curb carbon emissions.

The point is that nobody knows how high the carbon tax would
have to go to reduce emissions. It's a central planning problem. The policies being talked about now are really just exercises in experimental economics, pushed by speculative science.

What are the carbon emissions targets?

No carbon tax regime sets explicit emissions targets. The B. C. government said it would produce estimates of how much carbon emissions would fall as a result of its taxes, but no numbers have been produced so far. In fact, any carbon tax, no matter what its design, would be based on guesswork. They have no clue.

What are the side effects of carbon taxes?

Unpredictable, but undoubtedly dramatic. Economists' models are no help. Politics will shape the tax, applying it here and there as dictated by planners and the usual political pressures. Industry groups will fight for preferences, provinces and states will battle to protect their local economies, international trade will be at risk, developing countries will gain advantages. Carbon taxes, especially cap-and-trade systems, essentially require a total reordering of economic calculation around carbon atoms instead of money.

What do states do withall the new tax revenue?

This is the second part of the central planning nightmare. Local, provincial and national governments will begin massive planning efforts and plot new interventions to deploy the new tax revenues. They will claim to be "shifting" the revenue back to taxpayers through cuts in income and other taxes. They will want to use the new revenue to subsidize other non-carbon industries, and offset the burden of the carbon tax on injured industries.

That's consistent with Pigou's theory, which worked both ways. Not only should government tax to reduce the use of bad things, he thought government should subsidize good things, part of his belief that government should help distribute resources "in the most efficient way." His objective, he said, was to make it "feasible for governments to control the play of economic forces to promote the economic welfare, and through that, the total welfare, of their citizens as a whole."

So carbon tax programs are an experiment --although one that has already been tried. It imposes central planning on an economy based on carbon emissions rather than economic growth and welfare. It didn't work for the economy, it won't work for carbon.

FD says the way around this is to reconstruct industry and society to work on variable power.

That is nothing like what I said. There will be no need for people to be sitting in the dark.

Being a major coal miner and exporter

How major? I don't think we are as big a player as many make out.

Recall, however they quoted groups like ABARE and the Productivity Commission.

That doesn't make them economists either. Anyone can quote ABARE and then go on to say something stupid.

Unfortunately, little of what Pigou said on the subject of Pigouvian taxes is of any use to policy makers. How high should the tax be? How do you set targets for measuring effectiveness? What do you do about the side effects of the taxes? What do you do with the tax revenue?

Of course Pigou didn't predict everything, but you could get a reasonable prediction of the short term impact of a tax from modern economists. Over the long term there will be feedback loops. Also, taxes and trading schemes are not mutually exclusive. Even if we have a tax locally, we will still need an international trading scheme, or something similar.

With oil at $130 a barrel, we already have in place the equivalent of a carbon tax of about $300 a tonne.

Obviously coal is going to be reduced first. That's the beuty of pricing emchanisms - the highest value uses of fossil fuels are eliminated last.

No carbon tax regime sets explicit emissions targets.

There are not many carbon tax regimes around, but it wouldn't be hard to include an explicit target.

In fact, any carbon tax, no matter what its design, would be based on guesswork. They have no clue.

Not true.

Carbon taxes, especially cap-and-trade systems, essentially require a total reordering of economic calculation around carbon atoms instead of money.

No they don't. They just put a price on something that was previously free. There's nothing special about that.

What do states do withall the new tax revenue? This is the second part of the central planning nightmare.

Reducing other taxes is the obvious choice. Since when is having more revenue a nightmare? Whoever wrote this is a serious drama queen.

It imposes central planning on an economy based on carbon emissions rather than economic growth and welfare. It didn't work for the economy, it won't work for carbon.

No, it does the opposite. That's the whole point of carbon taxes, to avoid central planning. The author is an idiot.

Are there? Do you have some examples of these plans? I'd be totally amazed if you could take an exhaust stack and convert it to a CO2 extraction system by some process of retrofitting. Your retrofitting might leave the turbogenerators intact but that's about all.

The other question is - will this retrofitting technology be available within the projected lifespans of current coal fired power stations, or do we have to wait for the next generation?

Leakage doesn't seem to be much of a problem, it's under a lot of pressure remember. Sure it comes with a cost - so does every other low emission technology. Being a major coal miner and exporter it would surely be in our interests to pursure the technology in case the world becomes carbon constrained.  


From what I've read, that's the main thrust of the current research, and I'm not aware that any results have been published yet, so I don't know where you get this idea that it doesn't seem to be a problem.  

If it's not possible to maintain a leakage rate of less than 0.01% over a 1000 year period, the whole thing becomes unworkable, and that's the bottom line.

Well explaining it once would be nice Muso. Notice I have said where ever renewables have been tried they have needed massive back up - and you have not contadicted this. Yes, you mentioned how water is pumped back into to dams (but this is limited to areas which can have dams) and some unproven scheme of getting hydrogen from aluminium - I doubt very much this will be feasible on a large scale.

No one is saying clean coal is a sure fire certainty Muso. But that doesn't mean that it's not worth pursuing. Tim Flannery seems to think so:

http://news.smh.com.au/national/clean-coal-needed-in-23-years-flannery-20080526-2i87.html

Clean coal needed in 2-3 years: Flannery


Climate expert Tim Flannery says the coal industry should be penalised if it does not develop clean technologies within the next two to three years.

Professor Flannery was speaking at a local government managers' conference on the Gold Coast when talk turned to the viability of coal as an energy source.

The 2007 Australian of the Year criticised the coal industry for its reluctance to embrace "greener" technologies, despite being one of the biggest contributors to global warming.

"The coal industry never ceases to amaze me," the scientist said.

"They sit up there in central Queensland denying they've got a problem, raking in the profits ... (but) when is the day going to come when they dip into their own pockets to buy their industry a better future, a sustainable future?"

If the coal industry failed to act, he warned the world had as little as 10 years before it reached the point of "no return" and became irreversibly damaged.

"We should be demanding that the coal industry develops these technologies in the next two to three years, to demonstration stage, with penalties otherwise," Prof Flannery said.

The federal government also needed to boost its contribution from $100 million to $5 billion, recognising Australia's critical role in developing clean coal technologies, he said.

"I don't think anyone else can do the job," Prof Flannery said.

"No one else has the technical capacity."

Australia also had a global responsibility to pass that information on, especially to China, which builds about one new coal-fired power plant each week, he said.

He urged individuals to think green by cutting down on electricity and water use, as well as investing in carbon offset programs.

Councils also could do their part, he said, through leading by example and driving hybrid cars.

"If people see the mayor driving a big, clunky car, they're not going to buy (the environmentally friendly message)," Prof Flannery said.

"As councillors, there's huge things that can be done."

I think the point that Tim Flannery is making is that the coal industry is dragging its heels.

I know that's the case. It's procrastination on a major scale. I think it will become apparent that clean coal is on a parallel with the emperor's new clothes.

If they're going to do something, I agree that it has to be sooner than later.

The main problem is that the coal lobby is putting its weight behind a clean coal future that is unlikely to materialise, and diverting time and energy from proven renewable technology.

As far as petrol is concerned, if we really want to reduce the cost of petrol medium term, we need to add additional taxes to reduce the demand, then use the extra revenue to subsidise more efficient transport options, such as hybrids. Hybrids are not perfect, but they use half the fuel of a conventional vehicle the same size. If we had more hybrids, the demand for fuel would drop again, and the pressure 
for higher fuel prices would be eased.

Of course, such a course of action is political suicide. I tend to agree with Tim Flannery's statement today that Climate Change might be too difficult for governments to manage.

Just on the Rankine Cycle. It occurs to me that you guys might not appreciate how elegant that system is. I work with the technology every day, so it's second nature to me.

Basically there is a reversible chemical reaction:

Nitrogen plus hydrogen are combined at high pressure to give ammonia.
Heat is recovered from that reaction (think night time). The heat is converted to steam which drives a turbogenerator.

Now for the daytime reaction. The ammonia that was produced at night  is dissociated into nitrogen and hydrogen. That requires energy to be input. (From the sun)

The chemical equation is:

N2 + 3H2 <==> 2NH3

Very simple and elegant - and closed cycle. All the reagents are stored at ambient temperature, but very high pressure.

Muso, there is no need to subsidise hybrids. Simply putting up the price would be enough.

Labor runs into trouble with its green machines

http://www.theaustralian.news.com.au/story/0,,23818737-2702,00.html

KEVIN Rudd's key economic advisory body has rejected as economically unsound his $500 million plan to subsidise the development of a hybrid car in Australia.

The Productivity Commission has also queried the Prime Minister's promise that the Green Car Innovation Fund would spark greater car industry innovation, advising it would make more economic sense for Australia to import hybrid cars than to subsidise local models.

The commission said plans to slash tariffs on imported vehicles to 5 per cent in 2010 and scrap the previous government's $500 million-a-year Automotive Competitiveness and Innovation Scheme by 2015 would accelerate downsizing of the car industry.

But it found the economy would be $500 million a year better off if the Government went ahead with the scheduled cuts, because of lower car prices and savings on subsidies.

The criticism came yesterday as Mr Rudd used World Environment Day to hail his $500million fund as a boon for the environment and the potential trigger for the recovery of the nation's car manufacturing industry.

The car sector employs 66,000 workers but has lost 11,000 since 1996, including 930 when a Mitsubishi plant in Adelaide closed earlier this year.

The decline has come despite taxpayer-funded support including tariffs on imports and direct subsidies worth $1.1 billion in 2006-07.

Mr Rudd told parliament yesterday a locally produced hybrid car would revitalise the industry while also reducing carbon emissions.

"The Government's view is that we need an Australian automotive sector that is sustainable in all senses - economic, social and environmental," the Prime Minister said.

"When all is said and done, we do not just want a green car - we want a green car industry - and industry that can provide secure, high-skill, high-wage jobs by meeting the global demand for a wide range of greenhouse-friendly technologies and an industry that is itself a model of clean and green production."

Labor promised its GCIF during last year's election campaign. Starting in 2011 - after the next scheduled election - it will draw on the fund to pay car manufacturers $1 for every $3 they spend on the development and manufacture of low-emission vehicles.
Mr Rudd has also commissioned former Victorian premier Steve Bracks to review the car industry and suggest ways to improve its efficiency and protect jobs while reducing carbon emissions.

As Mr Rudd told parliament yesterday that high fuel costs and climate change demanded government action on a hybrid car, the Productivity Commission said it was unwise to subside cars that would otherwise be uncommercial. "Assisted green car production is unlikely to lead either to innovation spillovers or lower greenhouse emissions," said the report commissioned by Mr Bracks, whose final study is due by the end of next month.

"The GCIF will likely encourage some buyers to switch from taxed, more efficiently produced imported hybrid and fuel-efficient vehicles to subsidised, higher-cost, locally produced ones - without markedly increasing green car sales overall."

Industry Minister Kim Carr, who is about to travel overseas to lobby manufacturers with Australian operations to access the new GCIF, said through a spokeswoman last night the fund would go ahead regardless of the commission's view.

The Federal Chamber of Automotive Industries attacked the commission report as flawed.

"To state that an innovation fund aimed at reducing emissions will not result in innovation or reduced emissions shows the commission's poor understanding of the competitive influences in the industry," said FCAI chief executive Andrew McKellar. "The commission's report ignores the fact that the automotive industry is Australia's most valuable exporter after mining and that product innovation is essential to maintaining global competitiveness."

The commission's suggestion that the closure of more manufacturing facilities could boost the fortunes of remaining manufacturers was disturbing, he added.

"It is based on the false assumption that the cost to the economy of the closure of one or more vehicle manufacturers will be picked up by other car makers in the economy," he said.

Mr Rudd said his approach would help the car industry reinvent itself.

Opposition Leader Brendan Nelson backed Mr Rudd's efforts to cut greenhouse emissions but said Labor's policies were inconsistent, with imported hybrid cars subject to the same level of tax as petrol-guzzlers such as Hummers.

Hybrids don't make a lot of economic sense being at least $14,000 dearer than a turbo diesel car which gets close to hybrid like economy. Then there's the fact that you are up for many thousands to replace the batteries after ten years. Getting a smaller petrol car makes more sense also. How much do you wan't to put up the price of fuel to hake hybrids an attractive alternative FD?

Muso asked for some sources regarding some of my earlier comments. Here's an article that covers some of the same ground as well as supplying sources:

Global warming, an unsettled science

Image: CIA Factbook
The thesis of man-made global warming has been portrayed as a scientific consensus, but is this more a policymaker and media phenomenon than a settled matter?

By Simon Roughneen for ISN Security Watch (30/05/08)

In 2007, the Intergovernmental Panel on Climate Change's (IPCC) Working Group One, a panel of experts established by the World Meteorological Organization and the United Nations Environment Programme, issued its Fourth Assessment Report. This included predictions of dramatic increases in average world temperatures over the next 92 years and serious harm resulting from the predicted temperature rise.

Founding director of the UN Environment Programme Maurice Strong once analyzed global environmental challenges as follows:

"We may get to the point where the only way of saving the world will be for industrial civilization to collapse."

"Industrial civilization" has been pumping additional carbon dioxide into the earth's atmosphere and adding to the greenhouse effect, whereby carbon dioxide, methane and water vapor combine to trap sunrays bouncing off the earth's surface, keeping the earth at a temperature conducive to supporting life.

What ultimate benefit the collapse of industrial civilization could bring at a time when - as Oxford University economist Paul Collier put it in his award-winning book The Bottom Billion - around four billion people are being lifted out of poverty, remains unclear.

However, the IPCC outlines that "deep cuts in global emission will be required," while the European Commission supports emissions cuts of 25-40 percent by 2020. The US, however, considers such cuts beyond reach, at least before 2050, while Japan says it is premature to commit to 2020 limits.

On 26 May, G8 environment ministers endorsed slashing greenhouse gas emissions in half by mid-century, but failed to agree on much more contentious near-term targets.

Environmentalists were disappointed, according to AP reports: They missed the "opportunity to accelerate the slow progress of G8 climate negotiations, but they failed to send a signal of hope for a breakthrough," said Naoyuki Yamagishi, head of the Climate Change Program at WWF Japan.

Whether or not such emissions cuts, and the industrial and economic turmoil that could ensue, are necessary, depends precisely on whether global warming or climate change is man-made, or whether the anthropogenic aspect outweighs natural factors.

On 10 May 2007, UN special climate envoy Dr Gro Harlem Brundtland declared the climate debate "over," adding that "it's completely immoral, even, to question" the UN's scientific "consensus."

Questions about the "consensus" are mounting, however, as are apparently growing numbers of scientists who dispute the notion that "the science is settled."

Unraveling consensus
All four agencies that track Earth's temperature - the Hadley Climate Research Unit in Britain, the NASA Goddard Institute for Space Studies in New York, the Christy group at the University of Alabama, and Remote Sensing Systems Inc in California - report a 0.7C cooling in 2007 - a reversal of the warming that has taken place over the 20th Century.

A recent study in the journal Nature by scientists from the Leibniz Institute of Marine Sciences at Kiel University, postulates that global temperatures are unlikely to rise again until around 2015-2020, after a decade-long leveling-off since the 1998 recorded high. In other words, it is possible that by 2020, the world will not have warmed for over 20 years.

Dr Vicky Pope of the Hadley Centre at the UK Met Office told ISN Security Watch that natural climate variations linked to the Pacific cooling system known as La Niña, as well as a cooling phase of a system of Atlantic currents, contributed to the 2007 cooling and what the Leibniz/Nature study predicts for the coming decade.

The climate prediction modeling system used by the IPCC postulates that global temperatures will rise in tandem with carbon dioxide emissions, and at an unprecedented and dangerous rate, hence the need for, if not the collapse of industrial civilization, then reductions in carbon emissions as outlined since the Kyoto agreements in 1998.

Another study published in Nature in mid-May postulated that "Changes in natural systems since at least 1970 are occurring in regions of observed temperature increases, and these temperature increases at continental scales cannot be explained by natural climate variations alone," and that man-made climate change is having "a significant impact on physical and biological systems globally."

Speaking about this study to the Financial Times, Barry Brook, director of climate change research at the University of Adelaide, said: "[We should] consider that there has been only 0.75ºC of temperature change so far, yet the expectation for this century is four to nine times that amount."

However, Richard Lindzen (Alfred P Sloan Professor of Atmospheric Sciences at Massachusetts Institute of Technology), told ISN Security Watch that predictions such as the IPCCs were based on flawed modeling:

"The text of the IPCC [as opposed to the spin-oriented summary] makes clear that a major assumption of attribution studies is that the models were used properly and adequately account for natural internal variability. This study acknowledges that they did not. Under the circumstances, it is absurd to depend on these same models to predict the end of phenomena that they could not predict in the first place."

Dr Pope conceded that "climate science is an evolving subject," but in reference to the second Nature study, said that "they looked at secondary impacts of climate change, and made a stronger link back to core causes, along the lines of the latest research being done on this issue."

Arguments over the reliability of climate models have emerged at various times, in recent years. Most notoriously, the "hockey stick" graph used by the IPPC showing a rapid temperature rise over the industrial era was revised after allegations that it glossed over previously occurring natural cycles, including the Little Ice Age, running to around 1850, and the Medieval Warm Period, when temperatures may have been higher than now.

A warm Middle Ages saw vineyards in England, while Greenland got its name due to the relatively lush coastal regions encountered by contemporary exploring Vikings, whose villages there lasted until around the 17th Century, until a cooling climate reduced the snow-free land available to the settlers and indigenous people alike, leaving Greenland as we know it today. Needless to say, such temperature levels occurred well before any "industrial civilization" was in place to emit copious amounts of carbon dioxide.

But in response to counter-arguments to the man-made global warming thesis, the UK Royal Society has drawn up another point-by-point counter-argument, which states "our scientific understanding of climate change is sufficiently sound to make us highly confident that greenhouse gas emissions are causing global warming."

The Royal Society, however, goes on to outline: "While climate models are now able to reproduce past and present changes in the global climate rather well, they are not, as yet, sufficiently well-developed to project accurately all the detail of the impacts we might see at regional or local levels. They do, however, give us a reliable guide to the direction of future climate change. The reliability also continues to be improved through the use of new techniques and technologies."

In turn, Director of the Science & Environmental Policy Project S Fred Singer has responded to the Royal Society's position in a paper authored for the Centre for Policy Studies in London. And referring to the Leibniz Institute Nature study, he told ISN Security Watch that "natural climate fluctuations can be greater than manmade forcing," and that it is feasible that "the modeled manmade forcing has been greatly exaggerated."

The 4th IPCC report was released 10 months before it shared the Nobel Prize with Al Gore, and that publication made it clear that there was a consensus of 2,500 scientists across the globe who believed that mankind was responsible for greenhouse gas concentrations, which in turn were very likely responsible for an increase in global temperatures.

However, just two weeks ago, Dr Arthur Robinson of the Oregon Institute of Science and Medicine told the National Press Club in Washington DC that more than 31,000 scientists had signed the so-called Oregon Petition rejecting the IPCC line.

Moreover, some of those included on the IPCC's list have also raised objections. On 12 December 2007, the US Senate released a report from more than 400 scientists, many of whose names were attached to the IPCC report without - they claim - their permission. In the report, the scientists expressed a range of views from skepticism to outright rejection of the theory of anthropogenic global warming.

While the US remains outside the Kyoto system, along with developing-country high carbon emitters such as China and India, US President George Bush has made conciliatory noises on climate issues in recent months, while all three remaining presidential candidates have been vocal about their commitment to offsetting.

Less commented-upon is the data on emissions reduction: The US has cut the rate of increase of its carbon emissions more than any party to Kyoto, according to the Index of Leading Economic Indicators' figures for 1997-2004, the last year for universal emission data.

The US Senate will convene next week to discuss a climate bill, which aims, through a mandatory cap-and-trade scheme, to reduce emissions 70 percent from 2005 levels by 2050, even though countries such as China, Russia and India have no such plans.

Alarmism misplaced?
Prior to the December Bali climate summit, some of the scientists who signed the Senate and Oregon letters penned an open letter to UN Secretary-General Ban Ki Moon, outlining their view that climate alarmism was misplaced, and the policy options discussed were futile:

"The UN climate conference in Bali has been planned to take the world along a path of severe CO2 restrictions, ignoring the lessons apparent from the failure of the Kyoto Protocol, the chaotic nature of the European CO2 trading market, and the ineffectiveness of other costly initiatives to curb greenhouse gas emissions. […] Furthermore, it is irrational to apply the 'precautionary principle' because many scientists recognize that both climatic coolings and warmings are realistic possibilities over the medium-term future. […] The current UN focus on "fighting climate change" […] is distracting governments from adapting to the threat of inevitable natural climate changes, whatever forms they may take."

Whether this distraction results in the destruction of industrialized civilization or not, some analysts, such as Bjorn Lomborg, author of Cool It: The Skeptical Environmentalist's Guide to Global Warming, believes that an inappropriate reaction to global warming will cause more problems than contribute solutions.

Carbon trading has been pitched as part-panacea to man-made global warming. Stanford University academics believe that the system does little to prevent emissions, while cynics believe that proponents of the schemes can benefit financially - a sort-of counter-argument to the "big oil funds climate dissent" view held by green activists.

Problems aside, Dr Terry Barker, director of the Cambridge Centre for Climate Research, tells ISN Security Watch that the ongoing climate negotiations need to "establish a global carbon price through a global cap-and-trade scheme for international transport, not adequately covered by national jurisdiction."

He adds: "Governments need to agree to quantified targets [...] with a reasonable chance of achieving the EU's 2 degree target."

It seems that policymakers are in a bind: EU Environment Commissioner Stavros Dimas reacted to the Bali summit as follows: "Now the real hard work must begin. It is essential that the agreement to be worked out over the next two years is ambitious enough to prevent global warming from reaching dangerous levels."

And more incongruently, only last week, Slovenia's UN ambassador Sanja Stiglic, speaking on behalf of the EU, whose rotating Presidency Ljubljana holds, said that "the present [food] situation highlights the urgent need to reach ambitious, global and comprehensive targets for reductions in CO2 emissions."

The massive rise in world food prices in the past two years came to a head recently, with widespread food riots in numerous countries, and many analysts point to the diversion of cropland to the subsidized biofuels industry - aimed to curb carbon emissions - as a contributory factor to the food crisis.

Global warming, therefore, is causing the food crisis, but most directly through human efforts to prevent warming. In any case, the IPCC itself concedes that for a warming of anything up to 3 percent, "globally, the potential for food production is projected to increase."
