    Grim future for coast

    REPORT: The Climate Council says coastal communities can expect flooding unless climate change is addressed.
    REPORT: The Climate Council says coastal communities can expect flooding unless climate change is addressed.

    THE future for Bundaberg’s coast is grim unless action is taken on global warning, according to a major new report from the Climate Council.

    According to the report Counting The Costs: Climate Change And Coastal Flooding, Sydney, Bundaberg and Hobart would experience today’s one-in-100-year flooding event every day or so by the end of this century if global warning continues.

    “For a sea-level rise of only 0.5m, flood events that today might be expected once every hundred years could occur every few months in the future,” the report says.

    The report says a rise in sea level would be driven by the melting of ice in the Artica and Antarctic, and the fact that warm water takes up more space than cooler water.

    Bundaberg Deputy Mayor and Local Disaster Management Committee deputy chairman David Batt said the Climate Council report referred to coastal, rather than riverine flooding.

    “As such, the implications of coastal flooding due to sea level rises over 80-100 years are for coastal communities,” he said.

    “The risk that climate change-induced sea level rises has to all coastal communities, not just in Queensland, but Australia and around the world is something that has considerable scientific consensus.”

    Cr Batt said climate change had implications across an array of disciplines, from town planning to disaster management.

    “Local governments like Bundaberg Regional Council have to work carefully with the State Government on matters of long-term planning land use planning: the policy and ideology of this and future governments will be a factor in how communities adapt to climate change,” he said.

  • The dirty dozen myths of the RET debate

    Share story

    Much to the chagrin of opponents, the Renewble Energy Target has emerged from the Warburton Review as a policy for Howard’s battlers.

    Not discouraged by facts, economics or the laws of physics, the anti-RET lobby (led by the ‘Big Three’ retailers – Origin, AGL and Energy Australia) has conjured up various myths about the scheme. Here are the ‘dirty dozen’:

    1. The LRET drives up electricity prices

    Many studies have explored how the RET impacts the consumer’s hip pocket.  On balance, the net effect seems to be negligible either way, owing to this mechanism.

    Even the government’s own Warburton Review found that repealing the RET altogether would save each household a grand total of $1 (NPV) over the next 15 years. Other studies suggest that the RET delivers a net benefit to consumers – for example, Bloomberg New Energy Finance found that “Cutting or reducing the Renewable Energy Target is likely to result in … strong future increases in the price of electricity,”

    This of course ignores the more significant impact the RET has in driving down retail prices by enhancing competition (see Myth 2).

    2. The RET might reduce wholesale prices, but consumers won’t enjoy the savings

    In the Australian market, wholesale contract prices reflect (i) expected spot prices and (ii) the cost of insuring against the risk of high spot prices. The RET reduces (i), and makes no change to (ii). Accordingly, contract prices are reduced by the RET, and competition (itself enhanced by the RET) ensures that this benefit is delivered to consumers.

    Which leads us to the bigger point – retailers who support the RET are 20-30 per cent cheaper than retailers who oppose it.

    The Big Three energy companies control 75 per cent of the market, having emerged from state-owned monopolies. They are highly inefficient, lazy businesses that have relied on overcharging Australians for decades. Householders and businesses experience this as a “loyalty penalty” – the longer they have been with one of the Big Three, the more they pay.

    The RET is the only policy that encourages new entrants to make long term investments in this highly concentrated industry, a fact endorsed by the Consumer Action Law Centre and other consumer advocacy groups.

    Data published in a December 2013 report by the Essential Services Commission of Victoria revealed that electricity retailers backed by renewable energy generation are the cheapest deals in Victoria, when averaging residential offers reviewed by the ESC. Big Three retailers are being forced to offer discounts of more than 30 per cent just to stay competitive with these new entrants. If the RET is diluted, those discounts will disappear.

    Recent financial market announcements by the Big Three indicate they are already banking an uplift in profits if the RET is diluted. They won’t pass this on to consumers.

    3. The RET is just a cross-subsidy and is economically inefficient

    The RET has no cost to the Budget and is not a taxpayer subsidy. It imposes obligations on retailers to purchase certificates whose costs are (contrary to Myth 1) more than offset by countervailing reductions in wholesale energy prices.

    Consumer savings delivered by the RET do indeed result from regulatory intervention. But who cares, as long as Australians save money and it doesn’t impact the budget? The only net costs of the RET are borne by an unofficial cartel. Arguably, the Big Three are now just paying back what they have been pocketing from Australian consumers for years, and the RET is just redressing past government intervention – not dissimilar to enabling Optus (and others) to compete against Telstra.

    4. We don’t need the RET because the market is already oversupplied

    As an auction-based system that clears every half-hour, market “oversupply” is not technically possible. More supply is experienced by the consumer as lower electricity prices.

    The Warburton Review concluded that the RET was bad for the economy because it injected new supply into a market that was already well served. Such logic would suggest that Aldi building supermarkets to compete with Coles and Woolworths is also bad for the economy. How many consumers – who have benefitted from lower prices at Aldi, and even Coles and Woolworths – would agree with this?

    5. ‘Renewables cannot be relied upon because they are intermittent’, ‘Renewables don’t lower prices on high demand days’ and ‘Renewables cause network issues’

    If the market is already adequately supplied with generation capacity (see Myth 4), the intermittency of renewables is not a disadvantage.

    Empirically, renewable energy (both solar and wind) are significant contributors during periods of high demand. For example, a study of market pricing during the January 2014 heatwave by Sinclair Knight Merz revealed that:

    “In the seven days to January 19, wind farms contributed around 6 per cent of overall supply in SA and VIC, and as a consequence, wholesale prices were at least 40 per cent lower (on a consumption weighted average basis) than they would have been without the contribution of wind.”

    Recent AEMO studies confirm that the Australian network is capable of absorbing the levels of generation contemplated by the existing RET with minimal requirements for change, and the Warburton Review did not identify network capacity as an issue.

    More renewable generation means Australia is less reliant on coal and gas, both of which are exposed to the dynamics of global energy markets. (See Myth 6).

    Gas and other thermal based generation impose their own risks to energy security long-term due to risk of export market diversion of supply, potential for system-wide supply interruption, and failure of large format generators impacting networks.

    6. The RET is forcing gas plants to shut

    The federal government’s Energy White Paper Issues Paper notes the existence of “growing international demand and potential shortages of low-cost east coast gas”. To the extent that Australia’s electricity supply requirements are met by gas-fired generation, prices will be higher. To the extent that gas is withdrawn from domestic consumption in order to supply higher-priced export markets, there is a risk that security and reliability of electricity will be imperilled.

    In the long term, the availability of gas to meet domestic energy needs is a function of the whim of those who seek to maximise returns from their gas resources, whereas the economic imperative ensures that wind and solar plants (with essentially zero short-run marginal cost) always seek to maximise their output and have no alternate use for their fuel. To this extent, gas generation is likely to be more “intermittent” than renewable energy sources over the medium-long term, and substantially less predictable.

    In economic efficiency terms, to the extent that gas that is exported (as opposed to consumed domestically for electricity generation), this has a more positive impact on Australian GDP, provided that the displaced generation is replaced by a form of generation with a lower (or equivalent) cost. While the cost of wind is currently estimated to be higher than gas generation, even a modest increase in international gas prices could reverse this situation.

    By encouraging a diversity of fuel sources (which are not tied to international energy pricing) the RET provides insurance against the Australian economy being subjected to an energy crisis and/or a gas price squeeze, and any consequential GDP impacts.

    7. Large retailers have consumers’ interests at heart

    Only joking – see here.

    The behaviour of the Big Three in relation to the RET is quite predictable. AGL is a classic example. In their 2012 sub mission to the Climate Change Authority, AGL confirmed that it “is a strong supporter of retaining the RET in its current form”, highlighting “the significant financial cost associated with both reform to, and a repeal of, the RET policy.”

    Yet in the Warburton Review AGL’s position is reversed, campaigning for a substantial dilution of the policy. Why? Since 2012, AGL become the largest thermal generator in the country, buying Loy Yang and Macquarie Generation. It is now overwhelmingly in AGL’s interests to dilute the RET so as to extract higher wholesale energy prices from Australian consumers.

    8. The target is not achievable – there are not enough projects and they can’t be built in time

    Several studies have shown the 41,000GWh target is achievable, most recently the Warburton Review itself.

    9. ‘The LRET should only target 20 per cent of demand by 2020, and should be reduced to reflect falling demand

    The 41,000 GWh per annum target was designed to guarantee the delivery of renewable electricity generation representing “at least 20 per cent” of demand by 2020.

    The possibility that the target may exceed 20 per cent of total electricity demand is neither problematic nor unforseen.  Indeed, the intention of setting the fixed GWh p.a. target was to allow for exactly this type of variation of demand while delivering investment certainty.

    10. The cost of the RET is spiralling out of control

    Given that the RET is at worst cost-neutral to consumers (see Myth 1 and Myth 2) and does not impact the government budget, this myth is moot. But for completeness, the pricing of certificates is significantly below forecasts at the time of setting the target. As a consequence, the cost of the scheme is significantly lower than was planned.

    11. Renewables are putting existing generators at risk of withdrawal

    The withdrawal myth is not consistent with economic reality or the economic incentives of the current market. While some generators may currently be operating below their long-run marginal cost – and therefore incurring losses and (in some cases) an impairment of their ability to service equity and debt – it does not follow that plants will be withdrawn or shut down.  Provided that wholesale prices remain above the short run marginal cost and average fixed operating and maintenance costs, it will always be in the interests of equity and debt holders to continue to operate these plants.

    As wholesale energy prices are unlikely to fall below this level, the risk of premature withdrawal or failure is simply not real.

    Withdrawal of gas plant relating to LNG markets is a different matter and would occur irrespective of the operation of the RET (see Myth 6).

    12. The current political impasse results in unworkable uncertainty

    We addressed this in an article published in Climate Spectator last week, in which we concluded that the Warburton Review has laid the issue of policy uncertainty to rest once and for all. No sane political party would risk a promise to water down this extremely popular “battlers’ policy”, when there is no evidence that doing so would save consumers any money.

    The outermost shell of the Earth is constantly in motion. Over eons, our planet’s tectonic plates have dragged the continents apart and slammed them into one another, forming ocean trenches, mountains, and volcanoes.

    Plate tectonics explains continental drift, seafloor spreading, and why California has so many earthquakes. The Earth’s shifting plates also created an ideal environment for life itself to evolve and thrive. But exactly how our planet’s seven or eight major plates started shifting remains a mystery. Today, in a study published in Nature, researchers model the conditions that may have kick-started plate tectonics billions of years ago.

    “Over the past decade, we have kept with the idea that plate tectonics was not something that was born with our planet,” says Patrice Rey, a geoscientist at the University of Sydney in Australia and lead author on the study. “The Earth started with a stagnant plate. The question was, how do we move from there to a situation where we have plate tectonics?”

    A Hotter, Heavier Earth

    Modern geological plates move about in a predictable fashion. The top portion of a plate is relatively cooler and denser than the Earth below it, and this state of “negative buoyancy” causes one plate to slip, or subduct, under another. But scientists have long suspected that during the Archaean Eon, 2.5 billion years ago, geological plates were more static.

    “We look at these old Archaean crusts, for instance, and we don’t see the features that characterize subduction,” Rey says.

    This implies that some geological event must have initially set the plates in motion. Rey and his colleagues suspected that early Earth’s unique geology might have had something to do with it. Hundreds of millions of years ago, Earth’s interior was hotter and its crust was thicker. Rey wondered whether heavier continents might have pushed against nearby plates, initiating subduction.

    “Continents have a natural tendency to spread horizontally and push other plates on their sides,” Rey says. “When we put this physics into a computer model, we realized that it had the power to force the plate into subduction.”
    In the movie a continent (made of a depleted lithospheric mantle in green and continental crust in red) is slowly spreading toward the adjacent oceanic lithosphere (blue). A short-lived subduction zone develops following 45 myr of slow spreading. This subduction episode allows the continent to surge toward the ocean, leading to its “boudinage” and allowing the detachment of a continental block. This movie shows an 87 myr long story. (Credit: Patrice F Rey, Nicolas Coltice and Nicolas Flament)

    New Models for Ancient Problems

    The study presents a compelling story about how plate tectonics began. Continents grew denser, sank, and ultimately shoved their compatriots out of the way. Over time, these shoving matches developed into a familiar, self-sustaining cycle of subduction.

    For some experts, though the most exciting aspect of the study is that Rey and his team found a way to use modern techniques to answer very old problems.

    “What jumped out was that they could apply the modern tools of mechanical modeling to a problem that really pre-dates plate tectonics,” says Larry Brown, a geophysicist at Cornell University who was not involved in the research. “It’s tying it all together, with a nice dash of physical quantitativeness.”

    Nourishing Life with Rocks

    There’s also a curious link between the onset of plate tectonics and the evolution of biology. By moving landmasses apart and forming mountains and valleys, plate tectonics effectively gave rise to a number of unique ecosystems where new life forms could flourish.

    “If you want to have very vibrant viable biosphere with a lot of species, what you need is to provide lots of different ecosystems,” Rey says. “There’s a link between initiation of plate tectonics on Earth and the development of a strong and vibrant biosphere.”

    Rey and his colleagues are now preparing a more complete model, based on their initial findings, that would show how the continents themselves came to be. “What our model doesn’t cover is the formation of continents,” Rey says. “We’re working actively on that at the moment to bring that story into our model.”

    How the media shafted the people of Scotland.

     

    By George Monbiot, published in the Guardian 17th September 2014

    Perhaps the most arresting fact about the Scottish referendum is this: that there is no newspaper – local, regional or national, English or Scottish – which supports independence except the Sunday Herald. The Scots who will vote yes have been almost without representation in the media.

    There is nothing unusual about this. Change in any direction except further over the brink of market fundamentalism and planetary destruction requires the defiance of almost the entire battery of salaried opinion. What distinguishes the independence campaign is that it has continued to prosper despite this assault.

    In the coverage of the referendum we see most of the pathologies of the corporate media. Here, for example, you will find the unfounded generalisations with which less enlightened souls are characterised. In the Spectator, Simon Heffer mainatains that “addicted to welfare … Scots embraced the something for nothing society”, objecting to the poll tax “because many of them felt that paying taxes ought to be the responsibility of someone else.”(1)

    Here is the condescension with which the dominant classes have always treated those they regard as inferior: their serfs, the poor, the Irish, Africans, anyone with whom they disagree. “What spoilt, selfish, childlike fools those Scots are … They simply don’t have a clue how lucky they are,” sneered Melanie Reid in the Times(2). Here is the chronic inability to distinguish between a cause and a person: the referendum is widely portrayed as a vote about Alex Salmond, who is then monstered beyond recognition (a Telegraph leader last week compared him to Robert Mugabe(3)).

    The problem with the media is exemplified by Dominic Lawson’s column for the Daily Mail last week(4). He began with Scotland, comparing the “threat” of independence with the threat presented by Hitler (the article was helpfully illustrated with a picture of the Fuhrer, unaccompanied in this case by the Mail’s former proprietor). Then he turned to the momentous issue of how he almost said something wrong about David Attenborough, which was narrowly averted because “as it happens, last weekend we had staying with us another of the BBC’s great figures, its world affairs editor John Simpson”, who happily corrected Lawson’s mistake. This was just as well because “the next day I went to the Royal Albert Hall as one of a small number of guests invited by the Proms director for that night’s performance. And who should I see as soon as I entered the little room set aside for our group’s pre-concert drinks? Sir David Attenborough.”

    Those who are supposed to hold power to account live in a rarified, self-referential world of power, circulating among people as exalted as themselves, the “small number of guests” who receive the most charming invitations. That a senior journalist at the BBC should be the house guest of a columnist for the Daily Mail surprises me not one iota.

    In June the BBC’s economics editor Robert Peston complained that BBC news “is completely obsessed by the agenda set by newspapers … If we think the Mail and Telegraph will lead with this, we should. It’s part of the culture.”(5) This might help to explain why the BBC has attracted so many complaints of bias in favour of the No campaign(6,7).

    Living within their tiny circle of light, most senior journalists seem unable to comprehend a desire for change. If they notice it at all, they perceive it as a mortal threat: comparable perhaps to Hitler. They know as little of the lives of the 64 million inhabiting the outer darkness as they do of the Andaman islanders. Yet, lecturing the poor from under the wisteria, they claim to speak for the nation.

    As John Harris reports in the Guardian, both north and south of the border “politics as usual suddenly seems so lost as to look completely absurd.”(8) But to those within the circle, politics still begins and ends in Westminster. The opinions of no one beyond the gilded thousand with whom they associate are worthy of notice. Throughout the years I’ve spent working with protest movements and trying to bring neglected issues to light, one consistent theme has emerged: with a few notable exceptions, journalists are always among the last to twig that things have changed. It’s no wonder that the Scottish opinion polls took them by surprise.

    One of the roles of the Guardian, which has no proprietor, is to represent the unrepresented – and it often does so to great effect. On Scottish independence I believe we have fallen short. Our leader on Saturday used the frames constructed by the rest of the press, inflating a couple of incidents into a “habit” by yes campaigners of “attacking the messenger and ignoring the message”, judging the long-term future of the nation by current SNP policy, confusing self-determination with nationalism(9).

    If Westminster is locked into a paralysing neoliberal consensus it is partly because the corporate media, owned and staffed by its beneficiaries, demands it. Any party that challenges this worldview is ruthlessly disciplined. Any party that more noisily promotes corporate power is lauded and championed. UKIP, though it claims to be kicking against the establishment, owes much of its success to the corporate press.

    For a moment, Rupert Murdoch appeared ready to offer one of his Faustian bargains to the Scottish National Party: my papers for your soul(10). That offer now seems to have been withdrawn, as he has decided that Salmond’s SNP is “not talking about independence, but more welfarism, expensive greenery, etc and passing sovereignty to Brussels”(11) and that it “must change course to prosper if he wins.”(12) It’s not an observation, it’s a warning: if you win independence and pursue this agenda, my newspapers will destroy you.

    Despite the rise of the social media, the established media continues to define the scope of representative politics in Britain, to shape political demands and to punish and erase those who resist. It is one chamber of the corrupt heart of Britain, pumping fear, misinformation and hatred around the body politic.

    That so many Scots, lambasted from all quarters as fools, frauds and ingrates, have refused to be bullied is itself a political triumph. If they vote for independence, they will do so in defiance not only of the Westminster consensus, but also of its enforcers: the detached, complacent people who claim to speak on their behalf.
