GUEST POST: Good Planets are Hard to Come By – Andrew Glikson

ANU Earth and paleoclimate scientist Andrew Glikson puts an extraordinary amount of effort, well above and beyond the call of duty, into keeping the rest of us informed on the science behind the global warming issue.

The Earth’s climate system is commonly likened to a supertanker, meaning that in order to avoid disaster later in the 21st Century, we have to start turning the wheel now. Unfortunately there is a political problem in this, because the short-term interests of many in politics and business demand all ahead full.  –IM



 As sea level rises the planet is drowning in an ocean of untruths

 Andrew Glikson

Earth and paleoclimate scientist, Australian National University

We’re simply talking about the very life support system of this planet.  (Joachim Schellnhuber, Director, Potsdam Climate Impacts Institute, advisor to the German government.)

The sleep of reason produces monsters (Francisco Goya)

While Earth is undergoing a sixth mass extinction in its history, dominated by oxidation of hundreds of billion tons of carbon derived from fossil ancient biospheres, with consequent shift in the state of the atmosphere-ocean-cryosphere system, the feeble efforts of civilization to mitigate the climate is drowning in medieval conspiracy theories aimed against climate scientists by vested interests and fundamentalist man-over-nature ideologues.

The release of more than 320 billion tons of carbon (GtC) from buried early biospheres, adding more than one half of the original carbon inventory of the atmosphere (~590 GtC) to the atmosphere-ocean system, has triggered a fundamental shift in the state of the atmosphere at a rate of 2 ppm CO2/year, a pace unprecedented in the geological record with the exception of the effects of CO2 released from craters excavated by large asteroid impacts.

Carbon Abatement Submission (Senate Inquiry) CondensedThough air temperatures whether local or worldwide, daily or annual average, may for various reasons not reflect it, the world is none the less clearly warming. It is now possible to fulfill Lord Franklin’s dream and sail the Northwest Passage over the top of Canada from the Atlantic to the Pacific, at least for one month or so in the Northern summer. Possibly within the next ten years ships will be able drop anchor in an essentially ice-free Arctic Ocean, right at the North Pole. That together with the satellite altimetry data on sea levels  testifies to the rapidity of global warming, and of the onset of the positive feedback loops that can only further accelerate it. The safest assumption we can make, in short, is that we face a planetary climate emergency, requiring urgent economic reforms on a comparable scale to those which took place in Australia after the declaration of war in 1939…


Kangaroos, Thylacines and Aborigines 1As in other areas of human history, inference is needed for the Aboriginal past not only because there are controversial and politically sensitive areas, but because the documentary record alone is insufficient for sound judgement one way or another. While some might find certain inferences to be politically (and mythologically) attractive, on close inspection they turn out to be too improbable for acceptance. Such, I argue, is the case with Keith Windschuttle’s thesis on the demise of the Tasmanians, which he applies also to explain the declines of the mainland populations, namely that the bulk of it was the unintended consequence of introduced diseases, rather than the intended consequence of deliberate frontier violence…


Kangaroos, Thylacines and Aborigines 2 Beside European settlement, agriculture, rainfall and temperature, there is another, related distribution. It is that of the present day distribution of speakers of indigenous languages, mainly found today beyond the Europale. It shows that wherever Europeans settled, the native languages died out. The unavoidable conclusion is that conditions inside the Europale increasingly militated against aboriginal children learning their ancestral language in the process of growing up…

 The language decline correlates with the dilution of the aboriginal indigenous gene pool, as increasing numbers of people who describe themselves as Aborigines find themselves acknowledging, with varying degrees of enthusiasm, one or more Europeans in their ancestry…


Kangaroos, Thylacines and Aborigines 3The British perception was that the macropods were wild in the country and belonged to nobody. The ecological reality of Tasmania and elsewhere was that the biomass of available grass and herbage in any one period of time could feed a related biomass of herbivores only up to a limit, which in turn could support a limited biomass of omnivorous humans, their dogs and a net population of wild carnivores. The latter included dingoes on the mainland, where they had displaced thylacines; thylacines in Tasmania, and also the Tasmanian Aborigines’ dogs (gone feral) as the aboriginal populations crashed. Settlers everywhere in Australia honoured these principles every time they set about clearing the bush to make way for grass; ‘clearing off’ kangaroos and emus to make way for sheep, cattle or crops, and clearing off Aborigines to make way for themselves…


Kangaroos, Thylacines and Aborigines 4…Windschuttle’s Australia is one where the Aborigines went quietly to their fate as fringe dwellers of the country towns, and in marked contrast to their aboriginal counterparts in the Americas and New Zealand.

If there was no ‘warfare’ of whatever category involved in this transition, then the attendant and marked depopulation of the countryside and Aboriginal population decline can only be due to starvation and/or disease. Windschuttle won’t have starvation, but at the same time there are problems with the disease hypothesis that beg for a remedy, an explanation, or at the very least, a Band-Aid: which leaves warfare of some kind hanging around in the background.

And so we come to the elephant in the parlour of Aboriginal history…


Night Vision and BipedalismThis raises the intriguing possibility that before the discovery of fire and the invention of the thorn-fenced kraal, our distant African ancestors attained their relatively longer legs by wading, swimming and climbing for shelter at night up or down rocky cliffs, bluffs and outcrops, where long non-grasping legs provide no great disadvantage. For the climbing of trees, they do. Getting to where the predators cannot reach you makes poor night vision less of a disadvantage…


Plimer’s Climatology 101Plimer says that nothing humans do can affect the climate of the whole Earth, and that if it is warming, it is a good thing anyway.  Others disagree, and contend that climate change is occurring because of CO2 emissions. These latter were not put into the air for the purpose of warming the planet. Like the radioactive waste from the nuclear industry, they are a by product of another project entirely, to be justified after the fact…

Plimer’s Climatology 102 At a point in the long distant past someone extracted what was found to be useful fuel from a coal outcrop, and the coal industry was born. Only since the work of Arrhenius in the late 19thC have questions arisen about the basing of the steel, power generation and other industries upon it. Established industry has understandably reacted to the IPCC reports and scientific concern about greenhouse gases with counter-argument and delaying tactics regarding the transition to alternatives. Ian Plimer’s book and his talk to the Sydney Mining Club talk are best seen in this context…

Plimer’s Climatology 103The total yearly biomass production of the organisms on Earth is on one estimate at around 170 billion tonnes (164 billion tons)  of which a third is oceanic and two thirds terrestrial: say 60 billion tonnes oceanic. Assuming this roughly to be 10% of the total oceanic biomass brings the total mass of all marine organisms to 600 billion tonnes, or 600 Gt. The potential total CO2 addition to the hydrosphere of 4210 Gt (assuming it all finishes up in the oceans) is thus about 7 times the total biomass in the oceans. That is indeed significant…

Plimer’s Climatology 104…a two degree rise due to CO2 will produce a further two degree rise due to water vapour, making four degrees in all. The next domino to fall in this situation is the methane, locked up in arctic permafrost in Siberia and Northern Canada, and below the deep ocean floors as methane hydrates. In all those locations, it has built up from slow bacterial decomposition of organic matter. Methane is 45 times as powerful a greenhouse gas as CO2, to which it oxidizes in about a year after release to the air. The warming produced by this gas may in turn release the final nightmare gas, hydrogen sulfide. Plimer does not mention these potentially disastrous knock-on effects of methane and hydrogen sulfide…

Plimer’s Climatology 105: Lord Franklin’s Dream Turned NightmarePope aside, there’s no need to ask which embodiments of human stupidity Plimer might have had in mind. He has spent the preceding 483 pages denouncing them: ‘activists’, ‘environmentalists’, Greenpeace… but above all, Sir Nicholas Stern, Michael Mann, James Hansen, Al Gore, Ross Garnaut; other practitioners of the alleged quackery and pseudoscience of climatology, the IPCC, the Royal Society, the signers of the Kyoto Accord… If the book’s index was any good I could look them all up.

But that is only half of the last sentence. I have an uneasy feeling that behind the rest of it lies the profound theological thought that there will be no runaway greenhouse or climate catastrophe, because God will not allow it.


Plimer’s Climatology 106: His Lordship’s ListAt the end of his book, Ian Plimer hands over the keyboard to his lordship to deal with the question ‘What if I am wrong?’ In Plimer’s view Monckton (previously an economic adviser to Margaret Thatcher) had already dealt with it splendidly in a speech to the Local Government Association at Bournemouth, on 3 July 2008. So Plimer reproduces the speech in its entirety (with his lordship’s permission) on pages 489-493 of Heaven+Earth. We can take as noted the usual ‘ITS?’ (is that so?) in the margin against each one of the following points as they occur, and as well a ‘WIIFY?’ –  an abbreviated form of ‘what’s in it for you?’
