    A ‘test case’ for how undersea deposits of methane — a greenhouse gas locked in sediments — might respond to climate change has been uncovered in the Arctic Circle.

    The shallowest known deposit of methane hydrate — a crystalline solid comprising methane molecules trapped in an ice-lattice structure — has been discovered on the continental slope off Canada in the Beaufort Sea.

    The trapped gas deposit is located in an area of small conical hills on the ocean floor just 290 metres below sea level. Before the discovery, the shallowest known marine gas-hydrate deposits were found in the Gulf of Mexico and in the vicinity of the Svalbard Islands at depths of around 400 m, says Charles Paull, a senior scientist at the Monterey Bay Aquarium Research Institute in Moss Landing, California, who presented the work on Thursday at the annual meeting of the American Geophysical Union in San Francisco, California1.

    This particular deposit is only modest in size, but the methane trapped in such deposits represents an immense global carbon reservoir. Some experts fear that destabilization of such gas-hydrate deposits around the world — caused by changes in sea temperature or drilling, for example — could cause a release of methane into the environment and accelerate global warming.

    At such a shallow depth, the newly discovered deposit is vulnerable to decomposition if there is even subtle warming of the overlaying water, says Paull.

    The Arctic is thought to be undergoing some of the most dramatic effects of climate change anywhere in the world. And this particular deposit is just within what scientists call the ‘methane hydrate stability zone’, the range of pressure and temperature at which gas hydrates are stable. In this region, the stability zone begins at a depth of about 270 m, above which sea temperatures are too warm to ensure the methane remains locked in its water-molecule cage.

    Landslides and tsunamis

    Because this deposit is small, the methane released by its decomposition would not substantially affect the Earth’s climate, says Paull. However, the discovery could give some hints about, for example, how much methane could be released when a deposit begins to decompose as the sea warms.

    “This is a great place to study what happens,” under such conditions Paull says.

    Some climate scientists fear that gas-hydrate decomposition could also create geohazards — for example, by destabilizing the sea floor and causing landslides and accompanying tsunamis.

    Timothy Collett, a research geologist at the United States Geological Survey in Denver, Colorado, says that the shallowness of the deposit means it could help researchers identify signs of future events. But he urged caution in speculating about potential geohazards that might result from decomposition of methane hydrate deposits. “We don’t have proof in the geological record that any of that has ever happened before,” he says.

    Paull is now planning a more detailed survey of the structure, along with another two identified in the same area but at deeper depths to better track any changes related to global warming.

    Ukip’s Lord Monckton thrown out of Doha climate talks

    Party’s former deputy leader impersonates Burmese delegate and tells conference ‘there’s no global warming’

    Doha conference ejects Ukip’s Lord Monckton
    The former deputy leader of Ukip, Lord Monckton, has been ejected from the Doha climate change talks and permanently banned after impersonating a delegate from Burma on the conference floor.

    At one of the sessions, Monckton assumed the seat for Burma in place of the real delegate, and addressed the hall from his microphone. He spoke for nearly a minute, before being escorted out.

    He was ejected from the conference centre, had his badge revoked, and is thought to have left the country. The UN later confirmed he had been permanently barred from future rounds of the talks. Monckton did not respond to requests for comment by the Guardian.

    Monckton told the conference: “In the 16 years we have been coming to these conferences, there has been no global warming at all. If we were to take action, the cost of that would be many times greater than the cost of taking adaptation measures later. So my recommendation is that we should initiate a review of the science to make sure we are all on the right track.”

    He was booed and heckled by other delegates. Although Monckton is not ethnically Burmese, many small developing countries have advisers from other countries, so his appearance in the hall dressed in a business suit would not have raised suspicions.

    Earlier, Monckton had been seen dressed in a traditional Arab attire while distributing leaflets on his climate sceptic views.

    Monckton, who is the third viscount of Brenchley and does not sit in the House of Lords, is a well-known climate sceptic. He frequently gives lectures alleging that the scientific consensus is wrong. He worked for Margaret Thatcher’s Number 10 policy unit in the 1980s but joined Ukip in 2009 and became its joint deputy leader in June 2010. He relinquished his formal role in the party in the summer.

    The Qatari president of the conference, who was chairing the session, realised shortly after Monckton began speaking, at the informal stock-taking plenary intended to assess progress on the talks, that he was a phoney and stopped him.

    It is not unusual for people to be ejected from UN climate change meetings – some activists were made to leave earlier at this COP – for being disruptive or pulling stunts. However, impersonating a delegate is far more serious.

    The Burmese delegation was not available for comment.

    Nick Griffin, the BNP leader and MEP for the north west region is also at the conference. He said: “I am one of the few climate change sceptics, although I prefer realists. I’m here to keep an eye out to see if they have any crazy plans. Fortunately, their ambition is failing, so there are no crazy plans.”

    On Thursday, two activists were deported from Qatar after calling for more leadership on tackling climate change from the Gulf state, their campaign group said.

    Libyan Raied Gheblawi, 22, and Algerian Mohamed Anis Amirouche, 19, held up a banner in the conference hall’s central meeting point reading “Qatar, why host not lead?”

    “Both were stripped of their badges and asked to leave the hall by security guards. They were told to return to their hotels and be at the airport … ,” said a spokesman for IndyAct, a regional advocacy group on climate change policy of which both deportees are members.

  • Labor Party defies gloom as membership soars

    Labor Party defies gloom as membership soars

    Dec. 8, 2012, 3 a.m.

    THE recent soul searching about reforming NSW Labor in light of the corruption hearings involving former ministers Eddie Obeid and Ian Macdonald has at least one bright side: membership is up.

    See your ad here

    The general secretary, Sam Dastyari, said this week that in the past year the number of financial members had jumped by about 30 per cent. Who on earth is choosing to join Labor at a time when its stocks are at an all-time low? The party won’t give precise details, but says official figures show since last November, 4013 have signed up.

    With a median age of 37, they are hardly the next generation, but Labor says about 65 per cent live in its target seats in west and south-western Sydney, the central coast, the Hunter and regional and rural NSW.

    Membership is now at about 16,000 compared with an all-time low of about 12,000 shortly after the party’s 2011 election rout.

    The NSW branch alone accounted for more than half of the new memberships called for last year by the Prime Minister, Julia Gillard, who set a target of 8000 across all states and territories by the end of this year.

    The surge is being credited to innovative recruitment campaigns, including challenging existing members to sign up new members who could join for $5 each and the chance to win dinner with the former prime minister Bob Hawke. ”Members are joining the Labor Party at rates unseen since Gough Whitlam was prime minister and it’s because of [federal Opposition Leader] Tony Abbott,” Mr Dastyari said.

    But the former state Labor minister Rodney Cavalier questioned the quality of the new memberships.

    ”Most of the members of the Labor Party are no more than pixels on a computer print-out,” Mr Cavalier said. ”They do not do work of any kind in the Labor party”. Mr Cavalier described the $5 membership drive as ”a give-away” and said Labor’s challenge was to convince members to get involved in the party.

    It had been unable to do this due to the centralisation of power in head office.

    ”If the Labor Party was a physical entity like a bowling club, you would drive around NSW and find bowling greens full of divots and weeds,” he said.

    Mr Dastyari disputed this, saying the party had just completed a ballot in which 4000 members voted to select representatives to a national policy forum.

    ”Labor Party members are engaged and are getting more engaged as we head towards the federal election,” he said.

    The director of the NSW Liberal party, Mark Neeham, said there was always a need to question what Labor’s claims.

    ”They also said there would be no carbon tax and promised a budget surplus this financial year,” he said.

    Sparking outrage … the NSW Aboriginal Land Council has applied to explore for coal seam gas under 40 per cent of the state. Photo: Glenn Hunt

    THE NSW Aboriginal Land Council has applied to explore for coal seam gas under 40 per cent of the state, sparking outrage from indigenous and non-indigenous people alike.

    As a community meeting addressed by the Planning Minister, Brad Hazzard, was overrun by protesters at Lismore on the north coast this week, public submissions to the land council’s four separate applications closed.

    If successful, the land council, which is the peak body for all NSW local land councils, could gain mining rights to 321,300 square kilometres.

    In March Fairfax Media revealed the council’s initial foray into the resources sector, which would make it Australia’s first indigenous commercial miner.

    Aboriginal people need to work towards economic independence to end generational poverty, the council argues.

    It will not reveal its joint venture partner, saying only that it is in ”confidential negotiations with a potential” partner.

    One of the areas covers 65,700 square kilometres from Bathurst to the Victorian border, encircling the ACT on the way.

    Another runs from Coffs Harbour on the north coast down to south of Port Macquarie and west almost to Armidale.

    But the land council is up against huge opposition in the Northern Rivers region, where Aboriginal groups are as opposed as the sea- and tree-changers to searching for gas over 900 square kilometres from Tweed Heads to the Byron Bay hinterland.

    ”We’re totally against it,” said Yvonne Stewart, the chief executive of Arakwal Aboriginal Corporation at Byron. ”[We are] quite upset that they did not have the decency to come to the local level and inform people.”

    Parts of the application area overlapped with a native title claim and coal seam gas mining was anathema to the local Aboriginal tradition of environmental protection, she said. ”We’ve got to live here. We’ve got to swim here. We have to drink this water,” Ms Stewart said.

    Byron Shire Council has already publicly opposed the plan, which would extend into its shire from the Tweed.

    ”Coal seam gas is an absurd notion for Byron Shire,” the mayor, Simon Richardson, said.

    ”No one really knows who this land council is. They’re certainly not local,” he said. ”This sort of issue is a human issue. It’s not a cultural issue … It doesn’t matter what colour the person is if they want to drill on the land.”

    Tricia Magee, who has lived in the Byron hinterland at Coorabell for a quarter of a century, said she was shocked to learn of the plan to explore for gas under her home.

    Like most residents, she first heard of the proposal through an email that began circulating among locals last month.

    ”It’s additionally distressing that our local indigenous representatives were not informed and were not consulted and have indicated their opposition to it.”

    But the land council said it was not required to consult before applications were lodged.

    ”Prior to the applications being lodged there was no consultation because of the commercial in-confidence nature of the venture,” the chief executive, Geoff Scott, said.

    ”NSWALC’s decision to further pursue opportunities in the resource sector has resulted in widespread consultation with the land council network.”

    The council has described its move into mining as ”bold”.

    ”It was born out of frustration and an understanding that if Aboriginal people wait for government to invest properly in Aboriginal communities, they’d be waiting a long, long time,” a statement on its website reads.

    The land council originally lodged three petroleum exploration licence applications early this year. One, covering a large area around Wollongong, was rejected by NSW Trade and Investment, a state agency, in October.

    If the land council’s applications are successful, it can carry out surveys for 12 months. New licences would be required for drilling and seismic surveys.

  • Too many flying solo – councils ‘patchy’ on sharing

    Too many flying solo – councils ‘patchy’ on sharing

    THE sharing of services has been labelled “patchy and uneven” in a report looking at whether NSW councils should be amalgamated.

    A new, streamlined body called Councils of Mayors has been proposed if there are major mergers, forcing effective regional collaboration and resource sharing.

    “If a major restructuring of councils were to occur, the experience in Queensland suggests that there would be a period of considerable upheaval as newly created councils develop and implement new administrative structures and management systems,” the Enhance Regional Collaboration Amongst Councils In NSW paper said.”If the amalgamation process were to result in very large councils, these bodies would capture much of the potential economies of scale and scope in their own right.”

    Independent Local Government Review Panel chairman Professor Graham Sansom said establishing much stronger regional groupings of authorities was an important element of ongoing reform.

    Too many local councils, report finds»

    SYDNEY’S councils should be amalgamated, an independent sweeping review of NSW local government has found.
    ..

    “The paper we’ve released today suggests that one option would be to create powerful Councils of Mayors based on a modified version of current legislation,” he said.

    “These new organisations could undertake strategic planning and deliver a wide range of services on behalf of their member councils.”

    Prof Sansom said far-reaching changes were inevitable for local government throughout Australia.

    “We know that many councils in NSW are unsustainable in the medium-longer term,” he said.

    “We also know that a lot of local infrastructure needs urgent upgrading and that communities will need new and different services in 25 years time. Local government needs to change to adapt to this.”

    Staunch opponents to merger plans have been calling for more resource sharing, but the report found just 11 Regions of Councils, which consist of groups of geographically close councils, were buying together and only four shared commercial services.

    “While the initial changes could be instituted relatively quickly, the development of enhanced regional collaboration and shared services could take longer and the results are likely to be uneven,” the paper said.

    Investigations found some councils thought shared services were “at best a poor cousin of local government amalgamations in achieving greater efficiencies”.

    How fast does your truck go, Tony? That semitrailer you’re driving in your high-visibility vest? It’s fast enough to get you from Brisbane to Terrigal down the Pacific Highway in a couple of days so that you can talk about your plan to fix the road. And yes, you do have high visibility.

    The truck is like an industrial-strength version of the notorious red Abbott Speedos. It’s a high-visibility demonstration of masculinity, a touch daggy, a bit dated, very blokey, down-to-earth, virile, active, completely obvious. In the case of the Speedos, a little too obvious for most.

    But will your truck get you to the destination you’re suddenly so anxious to reach?

    You spent years, years of disciplined daily work, cementing your image as a destroyer. You campaigned against Julia Gillard, you campaigned against her asylum policy, you campaigned against her mining tax, and, above all, you campaigned against her carbon tax. As you well recall, you called for a “people’s revolt” over the carbon tax. You said the next election would be a referendum on the carbon tax.

    Advertisement

    It worked. You were thrilled to find how well it worked. You so frightened and angered the country with the prospect of the ruinous carbon tax that you put the Coalition into a commanding lead. You paid a high price personally – your approval rating went into a long and steady decline as you rammed home your persona as Dr No. But it was a price you were prepared to pay for a Coalition victory.

    But you didn’t imagine that it would take so long. You thought that Gillard’s grip on the Parliament would slip in the first year, and, when that didn’t happen, you expected that Kevin Rudd would force her out in the second. You didn’t expect that Gillard would still be in power, and you’d still be in opposition, when the carbon tax actually took effect and your dire prophecies proved false. Your unpopularity is at new highs and your party’s lead has weakened too.

    So now you want to be seen as a fixer, not just a destroyer, positive, not just negative: “Doctor Yes. Doctor Yes, no less,” as you told Adam Spencer on ABC 702 this week.

    That’s a big distance to cover. Can your truck get you to your new destination in just a couple of days? The culminating point of victory, as the great Prussian strategist Clausewitz liked to say, for you, Tony, was just before the carbon tax actually arrived. Your anti-carbon tax campaign is now delivering diminishing returns.

    When Boral announced the closure of a Geelong plant that makes clinker, a precursor for cement manufacture, this week, it was the sort of economic disaster scene where we would have expected to see the old Tony on the spot, crowing about the havoc wrought by Gillard’s carbon tax. Cement-making is an emissions-intensive business and the government was braced for an Abbott attack.

    Boral didn’t cite the carbon tax as a factor in the closure of the $100 million plant with its 90 jobs, but that hasn’t stopped Abbott in the past. Remember his interview with Leigh Sales where he pretended that BHP’s postponement of its Olympic Dam project was due to the carbon tax?

    But instead of talking cement, the new Tony was driving a truck, promising to fix the Pacific Highway, trying to reset concrete. The former US vice-president Walter Mondale once remarked: “Political image is like mixing cement. When it’s wet, you can move it around and shape it, but at some point it hardens and there’s almost nothing you can do to reshape it.”

    Is Abbott’s image still malleable? He has to hope so. Labor’s Craig Emerson said last week in Parliament that the “carbon price is much more popular than the Leader of the Opposition”. He based his assertion on a poll by Essential Media which didn’t quite support it. The poll didn’t actually test Abbott’s popularity.

    But it seems he’s pretty much right, according to the Fairfax pollster, Nielsen’s John Stirton: “Technically speaking, Tony Abbott is as unpopular as the carbon tax. In our latest poll, 36 per cent of respondents approve of Abbott, and 37 per cent support the carbon tax. The difference is statistically insignificant.”

    Similarly, the poll found that 60 per cent of respondents disapprove of Abbott while 59 per cent disapprove of the carbon tax. “They have a very similar profile,” is Stirton’s summary.

    Indeed, Abbott has the distinction of being the 13th most popular opposition leader of the 19 who’ve held the office in the 40-year history of the Nielsen poll.

    He has just slipped one place in the ranking in the last few weeks to fall below Gough Whitlam in his second term in the job, post-Dismissal, based on the average of the leaders’ approval ratings across their time in office.

    With one more month of ratings around his current dismal level, Abbott’s average will slip below that of Billy Snedden’s, Stirton projects.

    How did he get here? His approval ratings fell in tandem with support for the carbon tax. As he took the tax down, he went down with it. “He was successful in making himself and the carbon tax unpopular,” says Stirton. Abbott’s leadership has always been inextricably linked with the fate of the carbon tax. But he thought that he would rise as it fell. Instead they have fallen together.

    This week provided further evidence that the carbon tax is not the “wrecking ball through the economy” that Abbott promised. The national accounts showed that the rate of economic growth fell in the three months to the end of September. GDP grew by 0.5 per cent. Annualised, that’s a rate of 2 per cent and represents a loss of momentum.

    But it’s a loss of momentum that had nothing to do with the carbon tax, or the mining tax. The Gillard government and the state governments have to take part of the blame, but their contribution was through tightening their belts, not the new taxes.

    Cuts in government spending put a drag of 0.8 of a percentage point on the GDP growth rate for the quarter. The Coalition can’t very well attack that, though, because that is exactly what it keeps telling Labor to do – spend less. Economists generally concur that Wayne Swan’s promised surplus is a fiction. On this week’s numbers, the Association of Business Economists estimates that Swan is on track to deliver a deficit of about $8 billion instead of his promised surplus of $1.1 billion, but the government is not yet ready to concede that point.

    The carbon tax, in truth, verges on being trivial to the national economic outcome. The big story of the Australian economy, now, is the gradual subsidence of the mining boom’s first phase. That is, the phase of high prices for world iron ore and copper and coal supplies.

    Commodity prices peaked a year ago. Australia’s terms of trade – that is, what we receive for our exports compared to what we pay for our imports – fell by 4 per cent in the latest quarter. They’re down by 13.7 per cent over the year.

    In itself, that’s not necessarily a problem. The Treasury and the Reserve Bank have always known that the boom would end. The problem is that the shock absorber isn’t working. That’s the Australian dollar.

    The dollar normally rises and falls with commodity prices. This certainly worked on the way up. The strengthening dollar didn’t slow the mining sector, but it did punish the rest of the economy. Manufacturing, tourism, university education exports all became less competitive as the Australian currency became more expensive.

    But that pain was supposed to ease as the mining boom eased and the dollar fell. But the dollar is refusing to behave itself. It’s stuck stubbornly around $US1.04. Why?

    It’s partly a perverse price Australia is paying for being so successful during the global crisis of the last four years. Australia is one of the few AAA credit-rated countries left, and the International Monetary Fund has designated the Australian dollar, together with the Canadian Loonie, a global reserve currency. Other countries’ central banks have been stocking their reserves with Australian dollar assets. Their buying held the dollar up for months.

    Now another factor has come into play, and it’s another big inflow of foreign money. According to the economist Saul Eslake, a surge of direct investment in Australia, perhaps the capital to finance big new LNG projects, is again holding the dollar at levels it’s not supposed to be able to sustain.

    So instead of the seamless adjustment where mining gently falls and everyone else starts to revive, mining is falling but no other sector is benefiting. The shock absorber is stuck. As long as this remains the case, profits and incomes will stagnate and the Reserve Bank will try to take up the slack by cutting interest rates.

    This is the big story, and the carbon tax is a detail. The big story doesn’t work to the government’s advantage because it means that tax revenues fall. Even as Gillard announces the creation of a new category of government benefit, a National Disability Insurance Scheme, the nation’s ability to pay for it is declining.

    And it doesn’t help the Coalition either. Abbott, too, has pledged to find the extra $6 billion a year that the NDIS ultimately will require. But the money will not be there for him either. Nor will the $5.6 billion he has been pledging this week to fix the Pacific Highway.

    But in spite of this big underlying reality, both parties are busy promising spending they cannot afford. Honk if you believe!
