Peak Coal?

The New Scientist of 19 Jan 2008 carries an article, "Coal: Bleak outlook for the black stuff" (subscription required for full article), belatedly drawing attention to an interesting piece of analysis by Professor David Rutledge of CalTech in a lecture last October, where he suggests that world coal reserves are grossly overstated and could be substantially exhausted this century. It's well worth watching the whole hour of the lecture, because the PowerPoint alone [3MB] doesn't do his argument justice.

The implications of his work, if it should be borne out in the real world, spread all over the whole spectrum of debate on climate change, peak oil and oil substitutes. The good news? If he's right, there isn't enough fossil fuel around to get as far as the worst scenarios for global heating. On the other side, if he's right, the world economy is going downhill from about 2021 on, as the decline in energy supply enforces the end to economic growth everywhere whether we like it or not.

It turns out that Prof Rutledge is himself working from even earlier work from the German Energy Watch group. Their "Coal Report" from last March cast significant doubt on the declared coal reserves of many countries and predicted that world coal production could peak in the 2020s - essentially at the point at which China's production peaks, given that China is producing something like 50% of the world's coal production, yet is still a net importer of coal (as are all of the biggest producers other than Australia).

The Energy Watch analysis is a classic bottom-up survey of declared reserves and a check over the history of those reserves: the questions they raise over the validity of the statistics come from the many deep anomalies in the declared numbers. They point out that, in theory, reserves are the remaining known coal deposits that could be recovered with today's technology and prices. As technology improves and the price rises, reserves should increase, as more of the deposits could be economically mined. Now, both of those things have been happening for the last many years, with the coal price in particular increasing sharply alongside oil. And what has happened to the declared reserves? - they've gone down. In fact, they've gone down by considerably more than the amount that has been mined - at the extreme edge, Germany quietly reduced its declared reserves in 2004 by a mere 99% - from 23 billion tonnes to 183 million tonnes. Assuming that coal is not one of those rare goods that has a negative price elasticity, something else is going on, and the "proven reserves" are turning out to be nothing of the sort.

Prof Rutledge does something completely different to Energy Watch to make his own projections of coal production: he applies the toolkit of the Hubbert Peak analysis across from oil to coal. Briefly, for the not-too-mathematically-challenged, Hubbert's analysis takes oil production as being a normal (bell-shaped) curve - and we now know that Hubbert was completely correct on US oil production being that shape, and many other production curves have historically justified his assumption, for example the UK coal production curve in Rutledge's slides. Transforming that bell curve into a cumulative plot gives you a (much smoother) logistic S-curve. One more transformation of that curve, known as Hubbert Linearisation, brings us to the curve of production as a proportion of cumulative production to date. The useful thing about this curve is that 1) it's a straight line, 2) trending down and 3) where it cuts the X-axis is a prediction of the total all-time production limit.

Prof Rutledge also supplies a handy Excel spreadsheet with all of his data and projections, so you can have fun running your own alternative analyses if you so wish. Again, if you watch the lecture it will help understand the spreadsheet, particularly the several alternative production estimates for China. For our purposes, we'll stick with his best guess predictions.

His "top-down" core predictions differ in detail from the Energy Watch survey predictions, but the overall production curve is the same: to hit the high point, China is estimated to have 96 billion tonnes of usable coal remaining vs 44 billion tonnes extracted and 2.4 billion tonnes coming out each year (5 million miners, 4-6,000 deaths per annum from 5 accidents every day), hits the halfway point in ten years time, and it's all downhill from there, until by 2076 90% of all the usable coal in the world is exhausted.

One significant difference between the predictions is the ultimate total of coal extractions. Energy Watch quotes (but questions) World Energy Council reserves estimates as 4.5Tboe (trillion barrels of oil equivalent), while Rutledge puts reserves at 3.5Tboe and projected actual remaining production as 1.6Tboe. The surprising thing about all of these estimates is that ALL of them, including the "official" figures, are way below the numbers used in ALL of the IPCC scenarios, which work on an ultimate extraction of 18Tboe, with up to 11Tboe being extracted and burnt in this century.

Rutledge also revisits the oil and gas projections using the same techniques, with the usual observations about OPEC reserves and a production midpoint (aka "peak") also around 2020 - a relatively optimistic assumption compared to the ASPO worst-case. His figure for remaining oil and gas reserves is 3.2Tboe, vs declared reserves of 2.6Tboe. In parallel with the coal prediction, he points out that this figure is way below EVERY ONE of the IPCC scenarios, which assume 11-15Tboe burnt in this century.

What would this mean for the climate?

If Rutledge is right, there simply isn't enough fossil fuel in the ground to reach the more unpleasant end of the IPCC scenarios: the temperature rise he gets from plugging his numbers into a climate change model is 1.7°C - which is still enough to probably get to the death of the barrier reef and the melting of the Greenland ice cap, but not to the really nasty bits (see Six Degrees). He also points out that the world takes 800 years or more to recover from that rise, rendering the question of when exactly we burn the oil and coal relatively unimportant - if we burn it any time in the next few hundred years, we get the temperature rise - and anyway at least one degree of that rise is coming from the oil and coal we've already burnt - done is done.

This is pretty optimistic as global heating predictions run these days, and has been criticised for that by those who fear it could cause complacency - but complacency wouldn't be a reasonable reaction for at least three reasons.

1. Non-conventional oil

One of the obvious impacts of Rutledge's analysis is that in his "business-as-not-very-usual" scenario - ie with no externally imposed restrictions on burning fossil fuels - conventional fossil-fuel production peaks in 2021 and is pretty much over by the end of the century. If this is right, I can't see any prospect of stopping the exploitation of murky stuff like the Canadian and Alberta oil/tar sands, which probably only add 1Tboe at most, but have god-awful climate impacts, and would push that heating prediction over the 2°C which even the optimists agree gets us to "dangerous climate change". [Link is to another fascinating hour's video lecture by NASA's James Hansen on the CalTech site]

2. And then there's the impact on the economy ...

If fossil-fuel production peaks in 2021, as Rutledge predicts, then the main engine of economic growth is gone. World economic growth after that can only come from increases in energy intensity, ie the amount of GDP you get out of each unit of energy: historically, this has been quite appreciable, and in times of crisis has been as high as 1.5%pa; or out of growth in non-fossil-fuel sources of energy: wind, solar, geothermal, nuclear. For the last, let's just mention the term "Peak Uranium" and leave it at that (Energy Watch have a report on it). For the others, it would be optimistic to expect them to replace more than 15% of electricity production each over the long term - reversing some growth numbers out of that, electricity accounts for around 40% of fuel use, so in round terms 20% of total fuel use could come from them over 20 years or so - say a 1%pa growth in energy availability (possibly double-counted a little with that energy intensity growth number).

So, in a good year, the limit to economic growth will be 2.5% or less, and that drops to 1.5% or less after 2040 or so. World population growth rate is a little over 1.1%pa, so GDP/head growth would be limited to 1.4% or less to 2040, and three parts of bugger-all after that. Compare this to yesterday's IMF forecast:

The IMF's chief economist calls it a significant global slowdown. For the major developed economies, the IMF predicts continued, but much weaker, growth this year. The new forecast for global economic growth this year is 4.1%, after nearly 5% last year. There is a very sluggish period ahead for the main rich countries.

So, 4.1% will be very sluggish - how does a maximum of 2.5% or 1.5% sound?

3. and Food? and Deforestation?

The ability of the world to feed nearly 7 billion population is completely dependent on mechanised agriculture - without it, the carrying capacity of the planet is much lower. It probably won't come to that - but mechanised agriculture, like many other fuel uses, will probably be sustained by biofuels - ie diverting food production into fuel production, making foods as well as fuel scarcer and more expensive - and maybe promoting huge amounts of deforestation for palm oil production, adding significantly to Rutledge's global heating prediction. The good news for the world's agrarian societies is a major transfer of wealth from the eaters to the growers - but that probably doesn't include Australia: remember, in the three-degree world:

"The combination of fire, heat and drought will make life in Australia increasingly untenable as the world warms. Farming and food production will tip into irreversible decline."

and "none of the continent of Australia ... will be able to support significant crop production in the four-degree world".

Still, we'll be getting a good price for the coal.

Complacency?

So, I don't think Rutledge's predictions can lead to complacency. My problem, I guess, is that his predictions and the consequences outlined above are probably the most optimistic forecast I've seen lately, so I suppose I have to hope he's right ...

2 billion people lack any viable energy let alone green energy.

The troubling tension between propelling prosperity and limiting climate risks in a world still wedded to fossil fuels is on full display this week. India’s Tata Power group just gained important financial backing from the International Finance Corporation, a branch of the World Bank, for its planned $4 billion, 4-billion watt “Ultra Mega” coal-burning power plant complex in Gujarat state.

The I.F.C., along with the Asian Development Bank, Korea, and other backers, sees the need to bring electricity to one of the world’s poorest regions as more pressing than limiting carbon dioxide from fuel burning. The plants will emit about 23 million tons of carbon dioxide a year, according to the I.F.C., but using technology that is 40 percent more efficient at turning coal into kilowatt-hours than the average for India.

The decision powerfully illustrates one of the most inconvenient facets of the world’s intertwined climate and energy challenges — that more than two billion people still lack any viable energy choices, let alone green ones.

India and China continue to build coal fired power stations to provide energy for parts of their populations that still have no viable energy choices. This will push more C02 into the atmosphere and move the planet into more dangerous climate change. It is a dilemma that we need to really focus on. While coal remains the cheapest form of energy we will be putting the planet at risk. We need to put more money into research for alternative energy as well as putting a moratorium on our export of coal. We need to make coal more expensive so that it is not the cheapest form of energy.

Banks Blackmarking Coal?

Lester Brown, president of the Earth Policy Institute, has predicted that coal-fired power plants will be banned in the United States because of climate change concerns and the financial liabilities of greenhouse gas emissions.

Brown has said that one year ago, there were 151 proposed or planned US coal-fired power plants. About two-thirds of those proposals have been challenged legally or canceled.

"This is an extraordinary turnaround here in the space of one year. The overriding reason for this shift has been mounting concern about climate change," Lester said.

The other reason, he points out, is soaring construction costs (which have gone up 76 percent in the last three years).

The Fire They Say: Burns Within

Richard:  This humble moderator, sweating in the middle of what looks like being a ten-day autumnal heat wave, is uncertain about your climate change denial.

I sympathize with your predicament Richard, I really do. In a heat wave lots of liquids are apparently advised.

Having a get together this week; thinking about calling it: Bring the snow shovel or a kilo of coke.

I'm Freezing

A heart warming story doing the internet rounds http://www.theherald.co.uk/news/news/display.var.2100369.0.Crime_fighters_fears_of_new_drugs_influx.php

Ana Maria Caballero, adviser to the vice-president of Columbia, attended the conference to encourage those who take the drug to consider the impact on global warming.

"We have lost two million hectares of tropical rainforest as a result of the slash-and-burn techniques used by the drug growers," she said.

I would have thought that selling one's entire earthly possessions, and children into prostitution, would be something that would appeal to enviro-socialists - apparently not it would seem. I suppose all those bullet proof hummers do leave a carbon footprint. Next guy caught with a dime bag could always claim it is only being used to deal with the cooler than normal weather.

Richard:  This humble moderator, sweating in the middle of what looks like being a ten-day autumnal heat wave, is uncertain about your climate change denial.  You're right, though, Paul, in the likely success of such an argument

Forget fuel prices what about those who can't afford to eat?

The head of the UN World Food Programme has warned that the rise in basic food costs could continue until 2010.

Josette Sheeran blamed soaring energy and grain prices, the effects of climate change and demand for biofuels.

Miss Sheeran has already warned that the WFP is considering plans to ration food aid due to a shortage of funds.

Some food prices rose 40% last year, and the WFP fears the world's poorest will buy less food, less nutritious food or be forced to rely on aid.

Among the contributing factors to high food prices is biofuel production.

Miss Sheeran says demand for crops to produce biofuels is increasing prices for food stuffs such as palm oil.

Miss Sheeran said governments needed "to look more carefully at the link between the acceleration in biofuels and food supply and give more thought to it".

The WFP says countries where price rises are expected to have a most direct impact include Zimbabwe, Eritrea, Haiti, Djibouti, the Gambia, Tajikistan, Togo, Chad, Benin, Burma, Cameroon, Niger, Senegal, Yemen and Cuba.

Areas where the WFP is already seeing an impact include:

 

  • Afghanistan: 2.5 million people in Afghanistan cannot afford the price of wheat, which rose more than 60% in 2007

     

  • Bangladesh: The price of rice has risen 25% to 30% over the last three months. In 2007, the price rose about 70%.

     

  • El Salvador: Rural communities are buying 50% less food than they did 18 months ago with the same amount of money. This means their nutritional intake, on an already poor diet, is cut by half.

     

  • Anger over rising food prices have already led to riots in Burkina Faso, Cameroon, Senegal and Morocco.
  • As aid agencies struggle to feed millions of people we moan because of the extra dollar or two it takes to fill our gas guzzlers. As the price of energy continues to rise and we move to biofuels more and more will starve unless we change our attitudes.

    Poppycock

    John Pratt:  "Afghanistan: 2.5 million people in Afghanistan cannot afford the price of wheat, which rose more than 60% in 2007."

    However this year they did manage to increase the crop of poppies, a lot of which managed to find its way on to Australian streets.

    Simple Economics

    It's simple economics Alan, one acre of poppies gets you two acres of wheat.

    The age of Oil is at an end

    The Age of Oil is at an end. Maybe not this year. Maybe not for five years. But signs of the coming collapse are evident.

    Start at the White House. There, a week ago, President Bush touted tax breaks for oil companies that have just posted the largest profits in the history of American business. Yet he was dumbstruck when asked about the prospect of $4-a-gallon gasoline, a price that will force many families to choose between food and basic travel.

    “Wait — what did you just say?”, the president asked after a reporter solicited his advice for Americans facing that price, which was predicted by many analysts.

    “Oh, yeah?” Bush said. “That’s interesting. I hadn’t heard that.”

    He doesn’t get out much, understandably. But had the president been in California over the weekend, he would have found consumers paying what he apparently has yet to fathom — more than $4 a gallon at some stations.

    Bush is out of touch with the American people, who are struggling to pay $4 a gallon for fuel. Meanwhile Australians are paying about $7 a gallon.  The end of the oil age is something politicians the world over just do not want to face. What price will oil have to reach before we decide to take any real action?

    $7 a gallon? Luxury.

    John: ..."struggling to pay $4 a gallon for fuel. Meanwhile Australians are paying about $7 a gallon."

    $US7 a gallon is about $A 7.47 a gallon or about $A 1.97 per litre (there are about 3.785 litres per US liquid gallon).

    If we were back in Adelaide then the price at the Coles Express station nearby our old house is just under $A 1.46 a litre today. This works out to about $US 5.53 a gallon.

    Since we are not, the price of unleaded today in Villeurbanne ranges from €1.34 to €1.43 a litre. With the euro strengthening against the dollar, we are paying from $US 7.76 to $US 8.29 a gallon.

    $4 and $7 a gallon? I wish.

    $5 jump in oil price

    NYMEX closed $5 up on the day at a definitely and clearly all-time high with or without inflation adjustment: $104.52

    "Water, water everywhere ..."?

    John, "If you are planing a trip overseas looks like you had better make it in the next few years."

    And take your own water

    The three water crises – dwindling freshwater supplies, inequitable access to water and the corporate control of water – pose the greatest threat of our time to the planet and to our survival. Together with impending climate change from fossil fuel emissions, the water crises impose some life-or-death decisions on us all. Unless we collectively change our behavior, we are heading toward a world of deepening conflict and potential wars over the dwindling supplies of freshwater – between nations, between rich and poor, between the public and the private interest, between rural and urban populations, and between the competing needs of the natural world and industrialized humans.

    Around the world, more that 215 major rivers and 300 groundwater basins and aquifers are shared by two or more countries, creating tensions over ownership and use of the precious waters they contain. Growing shortages and unequal distribution of water are causing disagreements, sometimes violent, and becoming a security risk in many regions. Britain’s former defense secretary, John Reid, warns of coming “water wars.” In a public statement on the eve of a 2006 summit on climate change, Reid predicted that violence and political conflict would become more likely as watersheds turn to deserts, glaciers melt and water supplies are poisoned. He went so far as to say that the global water crisis was becoming a global security issue and that Britain’s armed forces should be prepared to tackle conflicts, including warfare, over dwindling water sources. “Such changes make the emergence of violent conflict more, rather than less, likely,” former British prime minister Tony Blair told The Independent. “The blunt truth is that the lack of water and agricultural land is a significant contributory factor to the tragic conflict we see unfolding in Darfur. We should see this as a warning sign.”

    Now if we could spare, say, $3 trillion, better yet, $6 trillion, and address the water crisis ... Oh!

    What is the future of the travel industry?

    In an interview with Global Public Media, Sir Richard Branson told journalist David Strahan that aviation could be made “truly sustainable” at the launch of test flight fuelled in part by coconut oil. But the Virgin boss conceded that meaningful supplies of alternative fuel might not be available before the advent of peak oil, which he said could happen within six years.

    Sir Richard later told GlobalPublicMedia.com that algae might provide enough fuel for the entire global aviation industry, and that such technological breakthroughs represented the only chance of avoiding peak oil – which otherwise might come within six years. Asked if jatropha or algae could be ready in so short a time he conceded this was a good question, and concluded that “we have to try our best to make them available as fast as we possibly can”.

    Aviation currently consumes 5 million barrels of jetfuel per day, or 238 million tonnes per year. Even with relatively generous assumptions about yield – say 2 tonnes of jatropha oil per hectare – replacing that would take almost 1.2 million square kilometres. To put this in context, D1 Oils, the British company pioneering biofuel from jatropha, plans to plant 10,000 square kilometres over the next four years.

    If you are planing a trip overseas looks like you had better make it in the next few years. This is another example of how our lives are going to change over the next ten years or so. We need to be planning for the loss of income when the tourist industry comes to an end.

    On the road to peak everything.

    Prices of rare metals like cobalt and magnesium are surging ahead in London, driven by high-end technology and soaring demand from economic powerhouse China, according to commodities experts.

    Glamorous raw materials such as precious metal gold and oil have long hogged the headlines -- with New York crude at a record high 101.32 US dollars per barrel last week on concerns about tight global energy supplies.

    But analysts say the lesser-known strategic metals, which also include cadmium, mercury and molybdenum, are now making headway. Other rare metals are antimony, ferrochrome, gallium, germanium, indium, manganese and tantalum.

    "China would be the main market driver for 75 percent" of the 30 most traded rare metals, said Martin Hayes, a senior analyst for specialist website MinorMetals.com.

    "The price gains reflect a combination of supply worries and demand influences."

    This piece in The Age is another warning that economies that demand continuous growth are about to run out of steam. Whether we like it or not we will have to move to  more sustainable economies. We will have to get better at recycling and reduce waste whether possible. We are well along the road to peak everything. There are limits to growth and economists should be working on sustainable economies rather than growth economies. Maybe a recession is a good thing.

    Oil really at $100

    Most people know that the $100 peak on January 3rd was an artifact - the price having gone above $98, one trader wanted to be the guy who first traded oil at $100 and made a trade that he promptly resold at a loss. Somehow, being "the guy who traded at a price in 1980 that arguably was more than $100 allowing for inflation depending on how you calculate it ** " doesn't have quite the same cachet.

    Well, this time it's staying there. 194,000 trades on Nymex yesterday, and settled 73¢ up, at $100.74. "I still think we're heading to 120 bucks, but it's still overbought," said Mark Waggoner, president of Excel Futures.

    ** CNN Money "Still, prices are still within the range of inflation-adjusted highs set in early 1980. Depending on how the adjustment is calculated, $38 a barrel then would be worth $96 to $103 or more today."

    Oil back over USD100

    NYMEX settlement price

    Also, belatedly to note that Alan Kohler picked up on peak platinum on Monday's seven-o-clock news.

    Oil Price May Double By 2012-2013

    Hi David. Check out this forecast. Keep in mind the oil price is already above the projection one month into the forecast period.

    World Oil Forecasts Including Saudi Arabia, Kuwait and the UAE - Update Feb 2008

    View the graph

    1. World total liquids production (Fig 1) remains on a peak plateau since 2006 and is forecast to fall off this peak plateau in 2009. Increasing numbers of oil experts are forecasting impending peak production plateaus. According to the International Energy Agency (IEA), the current peak production of 87.2 mbd occurred on January 2008. As long as demand continues increasing then prices will continue increasing.

    2. Forecast world crude oil and lease condensate (C&C) production retains its 2005 peak (Fig 2). The forecast to 2100 shows declining C&C production, using a bottom up forecast to 2012 (Fig 3). The forecast to 2012 shows a slight decline to 2009, followed by a 3%/yr decline rate to 2012.

    3. World oil discovery rates peaked in 1965 (Fig 4) and production has exceeded discovery for every year since the mid 1980s. Discoverable reserves in giant fields also peaked during the mid 1960s (Fig 5). The time lag between world peak discovery in 1965 and world peak production in 2005 of 40 years is similar to the time lag of 42 years for the USA Lower 48 (Fig 6).

    A better link and whither the road?

    The link I provided in my last post is not as good as this one, which in turn comes from a Science Daily report referenced by John Pratt.

    As I see it, Peak Coal and Peak Oil will if anything stimulate most national economies. Enormous sums presently sent to the OPEC countries can largely remain at home. The Furafuel process promises to make Australia at least self-sufficient in crude oil, and if promise comes to deliverance will form the basis of an export industry. For example, Old Man Saltbush, which has recently come back into vogue as a plantation feed for livestock, has a long plant life (estimated at 100 years per plant) and conceivably could provide through annual or biennial pruning a continuous and drought-proof source of feedstock for the biocrude industry; and that is just one species.  Those hardy and prolific plants such as Paterson's Curse, Galvanised Burr and Bathurst Burr which are now classed as weeds can at last appear on the asset side of the farm balance sheet, being likewise potential feedstock for a locally-based biocrude industry, along with crop trash and grasses.

    One simple fact reflects the enormity of the period of economic change we are now entering:  a great part of the energy, and pretty well all of the material now coming out of the coal and oil industries in future will have to come from the green plants. The list of materials (as distinct from fuels) includes plastics, paints, synthetic fibres, industrial and agricultural organic chemicals, and rubber. But the biggest of all by far is road tar.

    A highway engineer once told me that studies of abandoned roads he had been involved with showed that it only took around three years for plants to start colonising a macadamised surface. This is but one reason why road repair and resurfacing is a constant operation, like painting the Sydney Harbour Bridge. Concrete roads are hideously more expensive per kilometre than conventional tarred aggregate. So what happens to all the roads after Peak Coal? Tar sands would appear to be made to order here, as road building does not require combustion of the tar. But after them, the plants will have to fill that bill too.

    Peak used chip fat

    George Monbiot in today's Guardian: Apart from used chip fat, there is no such thing as a sustainable biofuel

      the [European] commission's methodology [in recommending a min 10% biofuel] has just been blown apart by two new papers. Published in Science magazine, they calculate the total carbon costs of biofuel production. When land clearance (caused either directly or by the displacement of food crops) is taken into account, all the major biofuels cause a massive increase in emissions.

    Even the most productive source - sugar cane grown in the scrubby savannahs of central Brazil - creates a carbon debt which takes 17 years to repay. As the major carbon reductions must be made now, the net effect of this crop is to exacerbate climate change. The worst source - palm oil displacing tropical rainforest growing in peat - invokes a carbon debt of some 840 years. Even when you produce ethanol from maize grown on "rested" arable land (which in the EU is called set-aside and in the United States is called conservation reserve), it takes 48 years to repay the carbon debt. The facts have changed. Will the policy follow?

    Many people believe there's a way of avoiding these problems: by making biofuels not from the crops themselves but from crop wastes - if transport fuel can be manufactured from straw or grass or wood chips, there are no implications for land use, and no danger of spreading hunger. Until recently I believed this myself.

    Unfortunately most agricultural "waste" is nothing of the kind. It is the organic material that maintains the soil's structure, nutrients and store of carbon. A paper commissioned by the US government proposes that, to help meet its biofuel targets, 75% of annual crop residues should be harvested. According to a letter published in Science last year, removing crop residues can increase the rate of soil erosion a hundredfold. Our addiction to the car, in other words, could lead to peak soil as well as peak oil.

    Removing crop wastes means replacing the nutrients they contain with fertiliser, which causes further greenhouse gas emissions. A recent paper by the Nobel laureate Paul Crutzen suggests that emissions of nitrous oxide (a greenhouse gas 296 times more powerful than CO2) from nitrogen fertilisers wipe out all the carbon savings biofuels produce, even before you take the changes in land use into account.

    Growing special second-generation crops, such as trees or switchgrass, doesn't solve the problem either: like other energy crops, they displace both food production and carbon emissions. Growing switchgrass, one of the new papers in Science shows, creates a carbon debt of 52 years. Some people propose making second-generation fuels from grass harvested in natural meadows or from municipal waste, but it's hard enough to produce them from single feedstocks; far harder to manufacture them from a mixture. Apart from used chip fat, there is no such thing as a sustainable biofuel.

    All these convoluted solutions are designed to avoid a simpler one: reducing the consumption of transport fuel. But that requires the use of a different commodity. Global supplies of political courage appear, unfortunately, to have peaked some time ago.

    But is Monbiot right?

    David Roffey: I'm not sure that Monbiot is right in this. The Furafuel process which has just been jointly announced by CSIRO and Monash University offers considerable promise. From the CSIRO website :

    Second generation technology recently developed by CSIRO and Monash University for producing a stable bio-crude oil from lignocellulose is on the table for turning cheap waste into valuable end products including petrol and diesel replacement fuels and other high value chemicals.
    Bio-crude works in much the same way as crude oil, yielding a stable product that can be produced in local areas from green waste and then transported to central refineries for further processing.
    “CSIRO is also looking at making other products currently derived from crude oil,” says Dr Simon Potter of CSIRO. “These products could range from biofuels or pharmaceuticals, to textiles and functional food additives.”
    “Products like paint and plastics traditionally form a large part of the output of crude oil refineries. Being able to make these products in biorefineries from oils derived from lignocellulose would help make biofuels themselves more economically viable.”
    Biorefineries reducing our dependence on oil, creating greener transport fuels and high-value co-products is one view of the future. Its potential depends on the cost and sustainability of feedstock production and developments in technologies for producing and utilising biofuels and these co-products.

    Apparently, the details of the process await passing the first stage of patent application. But as the finished biofuel would contain only carbon, hydrogen and perhaps oxygen as molecular constituents, the major inorganic plant nutrients could be returned to the soil. The organics, normally recycled through the soil most completely in virgin wilderness, are not by any means completely recycled in modern farming. Whereas plants and all consumers (herbivores and carnivores) are recycled by decomposing organisms in wilderness after they die, in farming the herbivores are trucked out the farm gate and pass over the breakfast, lunch and dinner plates of the nation, and their inorganic and organic constituents finish up in growing human and pet tissue, or else in sewerage outfalls to the ocean. In sheep-wheat areas, sheep clean up crop residues pretty much after harvest. Some carbon compounds go back to the soil via their manure, and some to market in sheep for slaughter.

    The inorganics have to be replaced from mined fossil sources (eg calcium, phosphorus, potassium) or from petrochemicals (eg nitrogen as ammonium salts and urea.) The organics finish up in the air via animal (including human) respiration. In other words, there is considerable carbon debt already.

    The CSIRO news release talks of local biofuel refineries as being the logical way to go, as they would reduce transport costs. As I see it, that makes it practical to return the sludge from the fermentation (or whatever) vats to the farmers for return to the soil. Running the first stage of the process on-farm, so that all that gets trucked out through the farm gate are compounds of carbon, hydrogen and oxygen in the biocrude, would be even better.

    For whatever reason (peak oil, peak coal, GW concerns) fossil fuel production and consumption will likely start falling starting dramatically in the very near future. Photosynthesis will then be on the way to overtake combustion and respiration, leading to a fall in CO2 concentration in the atmosphere. The green plants after all now have a large part of the carbon fossilised since the start of the Carboniferous to draw upon. Wherever it is, it is no longer locked up tightly out of their reach in the Earth's crust. As I have suggested elsewhere, the resulting drawdown of atmospheric CO2 could possibly land our descendants in a real humdinger of an ice age.

    At least, as you suggested in 'Peak Coal,' at least they/we might avoid cooking in runaway Greenhouse.

    Coal prices triple as supply crisis deepens

    Coal prices are predicted to hit $300 per tonne this week, a threefold rise that eclipses even the most bullish forecasts made just a few days ago. Experts say there is still no ceiling in sight and predict further upward pressure on European power prices.

    Last week Gerard McCloskey, publisher of McCloskey’s Coal Report, suggested that the export price of Australian steam coal, then trading at about $115 per tonne, might rise to $150. Last Friday it jumped to $140, leapfrogging the prevailing European import price, which includes transport and insurance costs. “We’ve never seen anything like it”, says McCloskey in an update interview with lastoilshock.com and Global Public Media, “and there’s no reason to believe that’s the end of the story”.

    US abandons clean coal

    New Scientist editorial, 9 Feb 2008:

    IF WE are going to carry on burning coal - our cheapest, most available, most abundant and most polluting fossil fuel - we urgently need to capture carbon emissions from coal-fired plants and bury them out of harm's way. So it is deeply worrying that the US, which has more coal than any other nation, last week cancelled its most ambitious plan to bring this technology to market.

    Just before Christmas, Mattoon in Illinois was selected as the site for the first large-scale demonstration project for carbon capture and storage (CCS). Now US energy secretary Samuel Bodman has pulled the plug (see "US government pulls the plug on flagship clean coal project"), a decision that looks likely to set back the development of CCS technology by three to five years. This is startling and dangerous. It suggests that the Bush administration's repeated promises to fast-track clean-coal technology were so much hot air.

    Equally worryingly, the decision seems to be part of a pattern. It is only nine months since BP pulled out of a plan to build a CCS power plant in Scotland whose carbon would have been buried under the North Sea in an old oilfield. It cited a lack of British government enthusiasm for underwriting the project as a reason to withdraw. The European Union has so far put very little flesh on its plan to have 12 demonstration plants for CCS up and running by 2015. Only Australia and China seem to be going to town on the technology.

    In fact, most of it already exists - including new combustion systems, the capture technology itself and underground burial of liquefied gases. What is needed is to scale it up and put it together in large demonstration projects. But these are costly, in the realms of a billion dollars, and neither industry nor government wants to bite the bullet.

    The US administration baulked at paying its $1.3 billion share of the Mattoon project. The European Commission announced two weeks ago that there was "no possibility of significant funding from the EU budget" for CCS. Meanwhile, the power and coal industries are unwilling to bet large sums on a technology that only makes sense when either coal-fired power plants without CCS are banned, or the financial penalty for emitting carbon rises to match the cost of keeping it out of the air.

    There has been a lot of talk in the past two or three years that the world can carry on burning coal because CCS is just round the corner, ready to be bolted onto coal-fired power stations from China to California. Cynics say this was always a smokescreen put up by a beleaguered industry and its political backers. If the proponents of coal really do think that CCS is the future, now's the time to show that the cynics are wrong.

    Panic all at sea...

    Ian MacDougall, here's my rejoinder;

    The boy stood on the freezing deck,
    raving like a loon!
    "If we don't all jump overboard", he said,
    "We'll all be drowning soon."

    "Put the ship hard to Left,
    don't worry about the facts!"
    "Opinions is what matters here!"
    "Let's panic to the max."

    "I've got the feelin' fate's at hand,
    so hysteria is a boon!"
    "We've no more hope of surviving this", he said,
    "than the Yanks have flyin' to the moon."

    "Get your knickers in a knot,
    "and stir a panic up in steerage!"
    "Let's make 'em frightened quite a lot,
    burghers, plebs and peerage."

    Craig Rowley: "Eliot, what Richard asked you to explain is how you could have been waiting for "over two years" to make particular a comment on Webdiary when you've been registered to comment as "Eliot Ramsey" for only 34 weeks.  So, what is your explanation?"

    Craig, what I actually said was this:

    "That's okay. I've been waiting for over two years for someone to bring up the 'Human-shredding-machine hysteria.'"

    If you go to the link I provided, you'll see the news item is dated December 6, 2005. That is, just over two years ago.

    That's when I clipped it.

    I was Eliot Ramsey then. And I'm Eliot Ramsey now. 

    I appreciate the subtle philosophical debate about whether a discontinuity of consciousness entails a discontinuity of personal being, and making allowance for occasional bouts of poor concentration, sleep and occasional alcohol induced unconsciouness, I've been me the whole time.

    Detroit whipping up hysteria over peak oil

    Roger Fedyk: "Eliot, I don't see the auto industry as doing anything more than hedging bets. The predominant automobile power plant for the forseeable future is the fossil fuel engine. Lots of talk about new technology but mainly "business as usual"."

    So 'peak oil' is a bit over-stated in your view? Maybe a bit 'panicky, even?  And by 'hedging their bets' is not Detroit merely cashing on on the prevailing...how shall we describe it?

    Hysteria?

    Richard, hi.

    I've been "waiting for over two years" to use the Iraqi torture victim's personal account of the disputed shredding machine because that's how long ago I first saw it in the Herald. I knew someone, somewhere would eventually dispute the machine's existence. I tuck things like that away for future reference. Endearing, no?

    Jacob was merely the first person in two years to walk into the cross-hairs. Sorry, Jacob.

    I have an absolute beauty ticking away concerning comparative per capita rates of capital punishment between countries that would defy belief were it not for the scrupulous research by the study's author.

    I cannot wait to pull that one.

    Cross purposes

    Eliot, we seem to be at cross purposes in our comments. My original comments were made in the context of "who's to benefit from the hysteria". If there is a hysteria, which I actually dispute, then the drivers are not obvious and we are left with the possibility that the general public are becoming just a teensy-weensy bit concerned about the earth going to hell in a handbasket.

    This is a perfectly understandable position except that it is still not an all-consuming public topic as the term 'hysteria' might suggest.

    The fact that we have rising greenhouse gas emissions is indisputable. The benign interpretation is that all is well in heaven, the draconian interpretation is that life will end. Both results are feasible and in most cases the result would be something in between. However, we are not gambling with poker chips or share markets or non-lethal outcomes. Factored into the mix is that if we f...-up, the end of human kind is on the cards.

    So why the cavalier attitude? When I measure my children's future and my grand-daughter's future and all the the future generations to come, I am not willing to take any risk. That is not hysteria. It is the most basic of human instincts, self-preservation and preservation of the genetic line.

    In my world, the gamblers don't get a choice on this. 

    Eliot is right, and will be right; right up to the big night

    Cut out all this hysteria!
    I know the North Atlantic!
    There are no icebergs up ahead,
    And so, no need to panic!
    Steam on, steam on, and shut your mouth!
    Don't say I'm looking manic!
    And while you're at it, shut your eyes!
    Said the captain of the Titanic.

    Please explain ...

    Eliot, what Richard asked you to explain is how you could have been waiting for "over two years" to make a particular comment on Webdiary when you've been registered to comment as "Eliot Ramsey" for only 34 weeks. So, what is your explanation?

    Some peaks are good

    Well, at least the drought has peaked here on the plains. It just won't stop raining now we want it to for a week or two so we can spray the pest weeds.

    The digit grass we planted ten years ago is above my head - a wonderful sight. But it won't last. We are already headed for the next big one. But why worry.

    Saw a report last night the Chinese are building a new city the size of Brisbane every month. Doesn't bode well for reducing greenhouse gases, or taking the pressure of resources of all kinds. The mind boggles as to what the demand in China would have been today without its one child policy.

    Yet here we are talking about a need to increase the birthrate in the West. It will be the expected population peak/explosion to 9 billion that will cause everything else to peak.

    Either we stem population growth, or we just blunder on to the inevitable conclusion. You don't have to be an expert in anything to see that. The lesson of Easter Island should not be ignored. But it will be. That is as certain as the next drought.

    Finally. After two years.

    Jacob A. Stam: "With apologies for going somewhat off-topic, but Paul's and Eliot's warnings regarding mass hysteria are quite apposite."

    That's okay. I've been waiting for over two years for someone to bring up the 'Human-shredding-machine hysteria.'

    And now the moment has arrived...

    This witness statement from Mr Ahmed Hassan Mohammed, 38, appearing for the prosecution at Saddam Hussein's trial:

    "I swear by God, I walked by a room and ... saw a grinder with blood coming out of it and human hair underneath," Hassan told the court.

    During the testimony, Barzan, sitting behind Saddam in the dock, interrupted Hassan, shouting: "It's a lie!"

    Hassan said: "My brother was given electric shocks while my 77-year-old father watched ... One man was shot in the leg ... Some were crippled because they had arms and legs broken."

    Richard: Eliot, according to Webdiary registration you've been here for (at time of writing)  34 weeks and eight hours. "...waiting for over two years" implies you've been here for three times that.  Please explain.

    Mass hysteria

    With apologies for going somewhat off-topic, but Paul's and Eliot's warnings regarding mass hysteria are quite apposite. We should never forget the Saddam-WMD hysteria that enabled the Great Mesopotamian Misadventure of 2003.

    And associated sub-hysterias: The 45-minutes-to-deploy-Saddam's-WMD hysteria. Human-shredding-machine hysteria. Nigerian-yellowcake hysteria. Anthrax-innoculations-for-our-soldiers hysteria. Babies-thrown-out-of-humidicribs hysteria.

    All converging into a critical hysterical mass, oddly these mass hysterias weren't propagated by non-governmental actors who stood to benefit from fostering undue public concern.

    Why?

    Eliot Ramsey and Paul Morrella have been running a line about "hysteria".

    I try to point out that their hysteria about this imagined hysteria is hillariously ironic. 

    My comments to that effect don't get published.

    Why is that?

    Richard:  Paul and Eliot also have had parts of their work edited.  I made my decisions last night based on the downwards slide of the tone of the conversation, and have been involved in decisions made today.  As you know, Craig, sometimes it's not a matter of specific language but also of semantics.  Let's move on, shall we?

    I wonder

    I wonder if anyone has taken the time to think about a scenario which I have been thinking could occur and we would have no hope of stopping its results. Please don't pick on my clear ignorance of the science involved. I do believe our atmosphere contains just 14%, or there about, oxygen in its content.

    Considering we are depleting rapidly the eco systems which generates oxygen by consuming Co2 and humans are consuming oxygen at an increasing rate, from population growth, heavy industry and transport. Is it not probable that our atmosphere may reach a stage where the oxygen content is diminished to where animal life will struggle to breathe.

    This scenario could be repeated within our oceans as they become more and more acid and stop producing oxygen, suffocating sea life and humans.

    Maybe we will peak breathable air, before long. Considering we are entering uncharted waters, anything is possible, isn't it?

    Hilarity Clinton.

    Roger Fedyk: "If business could make a squillion out of climate change fear then every corporation on this earth would be jumping up and down to scare the pants off us and get in on the feeding frenzy."

    Did you see the Detroit Auto Show this year? Hybrid this, hydrogen fuel cell that, electric something else. There was even a 'green' Ferrari.

    British Petroleum boasts of being one of the world's largest producers of solar panels.

    Paul Morrella: "Nothing exists like a US election for pure hysteria. So expect the hilarity hysteria to commence very shortly."

    Hilarity Clinton.

    Reactive Not Proactive

    Eliot, I don't see the auto industry as doing anything more than hedging bets. The predominant automobile power plant for the forseeable future is the fossil fuel engine. Lots of talk about new technology but mainly "business as usual".

    The drivers for action are the environmental groups who now have the ear of politicians particularly in Europe. Europe has long been more environmentally aware than the US, Australia or Asia.

    Business has mainly been hostile to change, and politicians in the grip of the fossil fuel industry have been implaccably opposed to doing anything at all until they have been steam-rollered by public opinion.

    One has to question what advantage can be garnered by the environmental lobby that would justify such a mammoth effort as has been on show for the past decade. Greenpeace, the World Wildlife Fund and other similar groups will never run countries and do not run businesses that are concerned with production and primarily profit.

    To assume that the build up in concerned public opinion is part of some woolly-headed, scientifically suspect, psuedo-religious fanatical display just does not pass muster. Too many of the finest minds in all walks of life are pressing for a pause in the headlong pursuit of profit so that we can make adjustments to out massive polluting of the atmosphere.

    My earlier questions regarding following a money trail are merely rhetorical. Personally, I don't believe that some awfully clever group of businesses are behind the push for action on climate change. I believe that it is a genuine, often frightened, response by ordinary people who have now been alerted that things are out of kilter. More than that actually; that things are now potentially dangerous for all life on earth.

    To portray the current concern as hysterical over-reaction or the work of some group with an unworthy agenda, as some are doing in this forum and elsewhere, is not very smart when the stakes are your very survival.

    The world has seen plenty of environmental disasters such as Chernobyl, Three Mile Island, Bhopal, Prince William Sound, Ok Tedi just to name a handful. These are major events with much associated death to many living things but they pall in to insignificance when compared to what happens if we stuff the atmosphere up by using it as a rubbish dump for industrial by-products.

    Prediction: Very Shortly World Climate Reports aplenty

    Craig Rowley

    If not an exact date, can you give us at least a rough date for when you reckon that'll "eventually" happen, Paul?

    Nothing exists like a US election for pure hysteria. So expect the hilarity hysteria to commence very shortly. Culminating in the ceremonial environmental blessing by Saint Al of a lass named Hilary or guy named Barack. Thus depending on ultimate outcome hysteria will either ramp up or become positive news. Most probably though a major economic downturn will kill this fad as dead as a dodo. Generally during such times people begin concentrating on issues that severely affect them like having a job. Paying pointless over inflated job destroying costs just doesn't seem to give the same bang for the buck during such times.

    kill to keep your job?

    Well, I'd always thought that many Americans would rather kill than lose their job, and it seems Paul Morrella is one of them.

    Clean coal is a fantasy.

    The federal government is facing a dilemma over its funding of the world's leading clean coal experiment after the US ended its commitment.

    The Bush administration blamed budget blow-outs for its decision to stop funding the $US1.8-billion ($2 billion) FutureGen project, Fairfax reports.

    The US decision is a blow to the Australian coal industry's hopes that a commercially viable clean coal plant would be built in the foreseeable future.

    Greens senator Christine Milne called on the Rudd government to pull taxpayers' money out of FutureGen and other projects, saying the Howard government's clean coal strategy had collapsed.

    "All the government money in the project from the Low Emissions Technology Demonstration Fund has all come to nothing," she said. "Government funding for FutureGen and any other clean coal pipedreams should be withdrawn in favour of renewable technologies that are up and running now."

    Senator Milne is right to urge the government to focus on technologies that have a better chance of success than wasting more money on the fantasy of clean coal. 

    Interesting Times

    David Roffey

    According to one trader, "supply is so tight at the moment that users just have to pay whatever producers are asking, and if they sit around and wait, they will either have to fork out even higher prices or be told there is no more tonnage available".

    Personally I would be financially extremely wary of believing this price surge will continue indefinitly. The new buzzword has become economic decoupling. The wish (need) to believe this will eventuate may induce many to overlook some glaringly obvious realities. The only real certainty is that the world is looking at some very interesting times ahead.

    Bio Crude.

    CSIRO and Monash University have developed a chemical process that turns green waste into a stable bio-crude oil. The bio-crude oil can be used to produce high value chemicals and biofuels, including both petrol and diesel replacement fuels.

    Another example of Australian technology that could be sold to the world.  

    Coal prices surge to new high

    BBC report:

    According to one trader, "supply is so tight at the moment that users just have to pay whatever producers are asking, and if they sit around and wait, they will either have to fork out even higher prices or be told there is no more tonnage available".

    Here We Go Again

    Roger Fedyk

    I doubt whether we are witnessing a scientific plot with Da Vinci Code overtones. Science wonks are not that well organised or adept.

    I also strongly doubt this is the case. Throughout history it has been proven hysteria isn't something that is driven by any one person or even one particular group - the term mass hysteria is used for that very reason.  Only in the "after hysteria" does it ever become clear who[m] gained most - sometimes not even then. In some instances it can be a number of interests often with one interest being in complete opposition to other. It may also be that the main drivers become the biggest after losers. It is rarely if ever possible to pin point the exact reason why mass hysteria begins or even why it just as quickly fades away.

    An example of mass hysteria many may remember is the "AIDS epidemic" - reaching its mass hysteria crescendo during the mid eighties. From nut jobs blaming the CIA or KGB all the way through to bible bashing doomsayers, and kooks wanting to teach condom use, and safe injecting measures to three year olds this period of mass hysteria had it all. From the downright dangerous: All high risk people should be segregated from society and denied medical treatment through to the plain nasty: Rednecks turning up with their "offspring" in mock coffins to make the point about who should be allowed in the schools, through to the plain wacky: Is the handshake really now a thing of a bygone in era in this new reality? No doubt others could give a thousand examples of similar cases of pure stupidity.

    Well for whatever reason the circus eventually left town, and people got on with their lives, and society got down to actually attempting to deal in a level headed way with what was, and still is a serious issue. Personally I can think of a few people in both politics and the media (still there only older) that would not like to be reminded about certain actions, and statements during this time (sheer embarrassment) - at least one of them is now in the process of running for President of the United States.

    Who gained the most from this mass hysteria? The answer to that would most probably depend on who you ask.

    Leaving It For The Bugs

    Paul, I think that it is incumbent on us to be focused, factual and free from generalisations.

    Firstly, I don’t actually see anything that I would classify as mass hysteria yet. People in the world are becoming more concerned and governments are trying to act on the perceived threat that comes from releasing billions of tons of CO2 and other greenhouse gases into the atmosphere each year.

    Here is an undisputed fact straight from your secondary school chemistry class; if you change the chemical composition of a gaseous mixture you change its properties and the way it behaves. No one can argue that human beings are not changing the chemical composition of the air that sustains us. The unknown is the extent to which the changes we are making are inimical to our way of life. The concern is that we are making changes that threaten the existence of a large part, or all, of the biosphere.

    Now if the changes we are making are relatively benign and slow-acting then we still need to be vigilant and take the necessary steps to restore what seems to be an optimal balance of all the gases that form our atmosphere. There is ample evidence that the health outcomes for so many people in the world are compromised by the industrial pollution that we create. Even thought we now are tending to live longer we are sicker with a range of “lifesytyle” diseases that were hardly in evidence prior to WWII.

    Bodies like the IPCC have made good faith attempts to quantify what the atmospheric changes mean and extrapolate their findings to predict the most draconian result. It would do no good for the IPCC and other scientific bodies to provide us with the rosiest outlook because we can assume that outcome without any deliberation and just continue doing what we are doing with our “she’ll be right, Jack” attitudes.

    However, the dangers posed by changing our atmosphere are deadly serious in their potential. What could such danger come from? Let’s draw an analogy from the phenomenon of nuclear fission. Forcing two pieces of fissile uranium together, making a ‘critical mass’, immediately commences a chain of reactions which in an controlled environment can be moderated enough to stop a runaway event that is an explosion.  The controlled environment is a nuclear reactor while the uncontrolled environment is a bomb. The runaway once started is unstoppable and the end result is violent in the extreme.

    The danger for the living organisms of this world is that we change the composition of the atmosphere enough to cause a thermal runaway event. Again, once started, it is unstoppable and irreversible. The only possible survivors will be thermophilic bacteria. This scenario is one of the possible outcomes of our changing atmospheric composition and we ignore it at our peril.

    Even the sceptics don’t deny the most draconian outcome is possible. They would consider the outcome has only a minuscule probability of happening. However, if we are to be hysterical about this possibility it is not a bad thing. Prudential behaviour, political responsibility, self-preservation or concern about our children’s future should all make us wary of doing anything that might extinguish life on earth.

    Regarding, your comments about the AIDS epidemic, I know something of it and remember the uninformed and unfortunate public and media speculation. My whole family have been involved in the real aftermath of HIV infection since 1990. We regard ourselves as well-informed and involved on a daily basis. My wife works for the Victorian AIDS Council. We have experience in this arena in the US, UK and here. Millions still die each year of AIDS and the threat is ever present and infections are rising in the Western world again.

    However, the threat from climate change is very different and will affect everyone, something that AIDS will never do. I repeat my earlier comment that if we are to have mass hysteria then climate change is just the thing to have it over.

    As to who benefits from fostering undue public concern, my point is that there are no obvious candidates. People instead have a visceral feel that in spite of the scientific and political confusion this is vitally important.

    The more important question

    Craig Rowley

    Paul, why did you make out that it was something you were predicting, something that would "eventually happen", if it was something you're now claiming has already happened?

    Just something I found on Google.

    Like the more important question should be: does this concern you? I know winning an argument on here is all important, but...they wonder why people turn their back on politics!

    Feeding the chooks...

    Roger Fedyk said::"Eliot, Bob Carter certainly does not say that climate change is not happening."

    I know Roger. I pointed that out. I actually stated:

    "He says Al Gore doesn't "present any evidence that climate during the 20th century departed discernibly from its historical pattern of constant change."

    The climate is changing. It just has not "departed discernibly from its historical pattern of constant change".

    Which is, of course, totally different to what fear mongers and hysterics like Al Gore and others on the 'band wagon' say.

    I realise that will be incredibly upsetting for a lot of folk who have their hearts set on seeing the sky falling down and squishing Chicken Little and all her friends.

    But they'll be fine. There'll be another hysterical fad by then.

    If it's not anthropogenic we're in real trouble ...

    Sure, the climate has been hotter than this - that's what underpins the certainties of the scenarios in Six Degrees, the fact that we can describe that hotter world by reference to paleoclimatology. But if it really is happening with no anthropogenic input we're in much deeper shit than we all hope, because that means these desperately unpleasant consequences are inevitable. On the other hand, even if they are inevitable, we can slow them down by curbing carbon emissions -so if Prof Carter is right, it is even more important to curb carbon emissions than if Al Gore is right ...

    The Climate Change See-Saw

    David Roffey: You stated in Six Degrees (linked to in your last comment on this thread): "We had all better hope that the current scientific consensus on warming, its causes, and what can be done, is right. If the skeptics are correct, and the warming path is determined by natural forces beyond our control, then the world of four, five or six degrees may indeed be inevitable. However, since there can be no serious doubt that climate change for at least the last half-million years has been closely associated with changes in greenhouse gas concentrations, we can  hope that action is still possible.

    "The other main skeptical claim, that the climate models are unproven and may be unreliable is more worrying, not least because this view is increasingly being held by climate scientists themselves. But the conclusions they draw from this are very different. Since the connection between greenhouse gas concentrations and climate has been established science for hundreds of years, and is one of the keys to explaining the planet's history for the last half-billion years, there is a missing link here, which is that greenhouse gas concentrations for the last few decades are much higher than they were in those past ages. This means that the climate may be much more sensitive to this than the models conservatively assume, and therefore the time we have left to alter the outcome is much shorter."

    That was well put. Drastic cuts to CO2 emissions are vital.

    The fundamental ecological idea of succession is relevant here. Any given community of organisms changes its environment in ways that can in turn lead to changes in species composition of it. One important example is the way a community of plants can change the characteristics of the soil it grows in, making it possible for new species to gain a foothold where none was available before, and in some cases in turn making it less possible for the originators of the change to survive, at least at that location. Thus a tipping point can be reached, as when a person starts walking from the lower end of a see-saw (an unfortunately extinct species of childrens' playground equipment) towards its higher end.

    We may be doing to the air what some plants do to the soil beneath them, and generating the humus of our own destruction.

    According to this source, since the Precambrian, average global temperature has varied between 12 C and 22 C - change being within a range of +/- 5 degrees from 17 C.  (In 2007  the average global temperature was 14.7 C.) That there has been an upper limit sustained through all the crises in the history of life testifies that runaway grenhouse, even if it does occur, will probably not turn the Earth into another Venus. The Earth clearly has a thermostat.

    The dark horse in all of this seems to be the effect of air CO2 on the oceans.

    Broadly speaking, melt water coming off the polar ice sheets could dampen the heating effects of atmospheric CO2 on the oceans, thus minimising cloud formation. However, once the polar ice sheets have melted enough, ocean temperatures would likely rise, generating more cloud in all latitudes, blocking the sun more often. The tropics, after all, are where the storm clouds gather. Water vapour trumps all other greenhouse gases well and truly.

    After atmospheric CO2 ceases to rise (there is only so much carbon available for release) and photosynthesis and other processes sweep it out of the atmosphere, this will possibly lead to an over-correction, plunging the average temperature to a new low and the Earth into the daddy of all ice ages.

    What goes up must eventually come down. But none of us now blogging will be around to enjoy the skiing, which is a pity, as I've always thought Ayer's Rock would be great for telemarking, and langlaufing through the Top End would be a sheer joy.

    David R: thanks, Ian. To repeat something from earlier, alluded to in your comment, the best guess recovery time for GHGs from a 450 peak / 2°C temperature rise would be 800 years or so, longer if we go higher; while ice-caps take tens of thousands of years to rebuild and get the water level back down - so I'm pretty sure we won't be there to see the recovery.

    Show Me The Money!

    Eliot, I was agreeing with you.

    However, you have ducked the main point of what I wrote. Nothing happens in the world of business or politics without an agenda. The agenda of Business is to make money. The agenda of Politics is to facilitate the distribution of largesse to those deserving souls (not welfare recipients) who patronise politicians.

    The issues around climate change see unwilling political actors and uncertain business actors. So if Bob Carter has a point, and you seem to believe he has, who, exactly, is going to make a killing here? He certainly does not seem to know and apparently, neither do you. Chicken Little analogies don't cut it. Show me the money!

    If business could make a squillion out of climate change fear then every corporation on this earth would be jumping up and down to scare the pants off us and get in on the feeding frenzy. It's not happening except amongst the "green" power technologists.

    That might just suggest something we need to be really concerned about.

    The band wagon

    John Pratt says:

    "Time to get on board the band wagon Eliot, you look increasingly isolated in you denial or reality."

    John, they had "droughts and flooding rains" when Dorothea Mackellar wrote that poem - in 1911.

    Professor Carter, at James Cook University, doesn't say climate change isn't happening.

    He says Al Gore doesn't "present any evidence that climate during the 20th century departed discernibly from its historical pattern of constant change."

    In other words, Professor Carter, too, isn't on the 'band wagon' - as you so aptly describe it.

    Carterisation

    Eliot, Bob Carter certainly does not say that climate change is not happening. He says unequivocally that it happens constantly and to this he adds the rider:

    In fact, there is every doubt whether any global warming at all is occurring at the moment, let alone human-caused warming.

    In this he is being ingenious by deliberately using the term 'global warming' when the peers that he derides use 'climate change'. The UN committee that is currently at the forefront of the political movement is the IPCC not the IPGW. The climate change advice is that cooling is just as likely an outcome as warming in many areas of the planet.

    Of course, if you read many of Carter's statements, he is not consistent in either his scientific terminology nor his overall message. It seems like he is continuously thrashing aorund trying to determine who he wants to attack, rescripting his message to suit the target. My sense is that Carter is also very much a political animal so what's in it for him?

    Let's assume the skeptics have their uses. In this we can use Carter and others to try and prevent the worst excesses of the 'headless chicken' that is politics. That neither makes him correct nor a rallying point merely a useful contra-opinion.

    What Carter does not identify and neither has anyone in this forum is what forces are truly driving the current debate. I doubt whether we are witnessing a scientific plot with Da Vinci Code overtones. Science wonks are not that well organised or adept.

    If "climate change" is a furphy, where does the money trail lead?

    Heading Toward Calamity

    Eliot Ramsey, taking a stab in the dark I would suggest the "dam reports" came about during a round of price rises (call me the suspicious type)? Why bother explaining the reasons for perhaps necessary price rises when the easier option exists, huh? And it of course can only make people more aware of the environment which ultimately can only achieve good irrespective of truth!?!?

    That is of course until your ten year old comes home from school explaining why he/she will only see twenty at best; fruit loops begin speaking seriously about releasing Ebola into the water system etc.........The thing with hysteria is when it comes to an end; nobody ever really meant to actually get taken literally.

    Perhaps the time is nigh for the real scientific community to take some control over this issue. You have at least provided a small example of a good start.

    Heading toward ... veracity?

    Paul Morrella: "Perhaps the time is nigh for the real scientific community to take some control over this issue."

    Any chance, Paul, that you could name for us just some of the leading lights of the real scientific community?

    How exactly do you think they should "take some control", Paul?

    Richard:  I've had to omit text from both of you two tonight.  Could you both please cool down?
