    Jim Hansen: Climate Change is the GOP’s worst nightmare

    Many conservative politicians have been among deniers, but ignoring the science will led to something the GOP dreads even more — big government.

    So argued Jim Hansen, who since 1988 has been in the forefront of the issue, first as a NASA scientist and more recently as a free-agent activist, in an interview Thursday.

    After an ill-fated, and it could be argued ill-conceived, attempt to pass climate legislation in the first year the the Obama administration there has been little traction on the issue. The federal Environmental Protection Agency is delaying its rules on carbon dioxide emissions from power plants and the new Department of Energy energy efficiency standards for appliances are also being delayed.

    And that’s okay with Hansen, who says he sees the solution coming in a different form, a carbon tax, and from a different place — the right of the political spectrum.

    “It has to be a carbon tax and it really has to come from conservatives,” Hansen said. The reason is that the tax has to be market-based and revenue neutral.

    “That money has to be given back to the public on a per capita basis so all legal residents of the country get an equal amount and that way the person who does better than average in limiting their carbon footprint would make money and then everybody in the country becomes an environmentalists whether they want to or not,” Hansen said.

    “The fundamental fact is that as long as fossil fuels appear to the public to be the cheapest energy we are going to keep burning them,” Hansen said.”Fossil fuels are not the cheapest energy they only appear to be because they are subsidized.”

    California Democratic Sen. Barbara Boxer and Sen. Bernie Sanders, a Vermont independent, have introduced a bill that would create a carbon tax, but that doesn’t make Hansen happy.

    “As usual the Democrats are going to take some of the money, 40 percent of it,” Hansen said. “Conservatives have to put ta foot down and say you can’t use this as another excuse to make government bigger. Democrats have a problem they can’t keep their hands off our wallets.”

    The reason Hasen is so adamant is by his calculation if the government keeps 40 percent most people will end-up paying more for energy than they get back. “It is important that all the money go to the public, so get this push from below,” he said.

    What of the general reluctance from anyone — and we mean just about anyone — on the GOP side of the aisle to take up the issue since Arizona Sen. John McCain and South Carolina Sen. Lindsay Graham abandoned their 2008 efforts to fashion bipartisan legislation?

    “If they continue to pretend that human-made climate change is a hoax, eventually you get to the point where nature makes it clear it wasn’t a hoax and then the public demands the government do something and that’s the worst nightmare for conservatives,” Hansen said.

    “It would allow the government to take over and do things by fiat, which not in anybody’s interest in my opinion, because the government never, seldom, makes the right choices,” Hansen said. “Let the market make the choices, which is a conservative approach.”

  • Glacier melt causes third of sea-level rise

    Glacier melt causes third of sea-level rise

    Columbia Glacier: The most significant ice losses occurred in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas (University of Colorado)

    Big melt Water from the world’s shrinking glaciers was responsible for almost a third of the rise in sea levels between 2003 and 2009, shows new research.

    An international team of scientist compared data gleaned from two NASA satellites as well as traditional ground measurements from glaciers around the world.

    Their work, published in the journal Science , is the most accurate estimation of how glaciers contribute to sea level rises to date.

    “For the first time, we’ve been able to very precisely constrain how much these glaciers as a whole are contributing to sea rise,” says lead author Assistant Professor Alex Gardner, assistant geography professor at Clark University in Worcester, Massachusetts.

    “These smaller ice bodies are currently losing about as much mass as the ice sheets.”

    The most significant ice losses occurred in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas, the study found.

    The glaciers outside of the Greenland and Antarctic sheets lost an average of roughly 260 billion metric tons of ice annually during the period, leading to a rise in ocean levels of about 0.7 millimeters per year.

    By contrast the glaciers in Antarctica, smaller ice masses that are not connected to the ice sheet, made scarcely any contribution to sea-level rise over the study period.

    “Because the global glacier ice mass is relatively small in comparison with the huge ice sheets covering Greenland and Antarctica, people tend to not worry about it,” says Tad Pfeffer, a glaciologist of the University of Colorado at Boulder.

    “But it’s like a little bucket with a huge hole in the bottom: it may not last for very long, just a century or two, but while there’s ice in those glaciers, it’s a major contributor to sea level rise.”

    Scientists estimate that if all the glaciers in the world were to melt, sea levels would rise by about 60 centimetres.

    However if the entire ice sheet of Greenland were to vanish, the oceans would surge by six metres. If the Antarctic lost its ice cover, levels would rise about 60 metres.

    The study used data from NASA’s Ice, Cloud and Land Elevation Satellite, or ICESat, and the Gravity Recovery and Climate Experiment, or GRACE.

    ICESat, which ceased operation in 2009, tracked glacier changes by bouncing laser pulses off the surface to calculate the shifting height of ice cover.

    The GRACE system works by monitoring variations in Earth’s gravity field caused by shifts in the planet’s mass distribution, including displacements of ice.

    “Because the two satellite techniques are subject to completely different types of errors, the fact that their results are in such good agreement give us increased confidence in those results, says study author Professor John Wahr, also from the University of Colarado.

    Advocate of stable population makes bid for ACT Senate

    MARK O’CONNOR is a somewhat reluctant politician, but for decades he has espoused the need for a sustainable population, born out of his interest in the environment, which he has documented around Australia, primarily through poetry.

    He is co-author of a book on the population topic, Overloading Australia, which Dick Smith sent to every federal and state politician, and every mayor.

    But with the major parties continuing to ignore population – what his Stable Population Party considers ”the everything issue” – Mr O’Connor, who also works as a marriage celebrant, is throwing his hat in the ring, running as a Senate candidate for the ACT.

    ”Until I was 30 I assumed there were old geezers somewhere who worried about the world … I think a lot of young people are that way,” the 68-year-old said.

    ”By the time they’re out of that phase they’ve got a family and their noses to the grindstone, so a lot of these groups, it’s retirees who power [them].”

    It’s one of many things the older generation are good for, he says, dismissing the notion that population growth is necessary to counter the ageing population.

    ”They’re raising this huge fear that there will be three times as many people over 65. But the point is that there are going to more people over 65, but there will be fewer people under 20, and the young are actually the most expensive in the population,” he said.

    ”Not only do they not produce anything themselves until such time as they finish their studies, but they pull other people out of employment – and they need constant minding. Very few old people need to be minded all the time.”

    There is plenty of economic theory to back up the objection to the Big Australia we are heading towards, with current growth at 1.7 per cent, a trajectory to 40 million by 2050

    Mr O’Connor points to US economist Lester Thurow’s estimates that spending 12.5 per cent of GDP is required to expand infrastructure capacity by 1 per cent a year, or about $200,000 per extra person.

    Against that necessary infrastructure spending, Treasury’s 2010 Intergenerational Report estimated 4.1 per cent of GDP would be needed for extra health and aged care, albeit using the figure of 35 million by 2050.

    ”Our [growth] levels are bizarre by First World standards,” Mr O’Connor said. ”Indonesia is 1.2 per cent – and actively trying to reduce it.

    ”[The birth rate] is just below two, which is exactly where it ought to be for Australia – nice, even-sided generations with some scope to bring in an excess of immigrants over emigrants,” O’Connor said.

    The problem, he said, was the ”very powerful business lobbies” that want higher immigration levels to create new markets and fill jobs with cheaper labour.

    ”Refugees are not the problem,” he said. ”They’re still just 5 per cent of the intake. You could double refugees if you wanted to and still reduce the immigration intake enormously. There’s no reason we are seeking this huge intake of people. Most First World countries are stable populations and the claim it makes you richer isn’t true either – the world per capita wealth table is dominated by countries under 10 million – most of the Scandinavian countries, for instance.”

    While Mr O’Connor is not optimistic about his own chances of election, he thinks the issue is gaining traction, and the electorate deserves a choice.

    ”Every nation has both a right and responsibility to keep its population in balance with its resources. The notion that you can grow forever is crazy economics.”

    Nationals Leader Warren Truss backed his party members, saying there was “widespread concern in the grain industry”.

    Nationals Leader Warren Truss backed his party members, saying there was “widespread concern in the grain industry”.

    THE National Party continues to pressure the federal government to block the $3.4 billion takeover of east coast grain handling giant GrainCorp by US multinational Archer Daniels Midland (ADM).The party’s Federal Conference in Canberra last weekend passed a unanimous motion calling on Treasurer Wayne Swan to reject the takeover bid.

    NSW Nationals Senator Fiona Nash and Nationals Riverina MP Michael McCormack have responded to repeated concerns raised by their grain growing constituents, about surrendering supply chain control to foreign multinationals, following the loss of single desk monopoly wheat export marketer AWB in 2008.

    Nationals Leader Warren Truss also backed his party members, saying there was “widespread concern in the grain industry” – also shared by his city colleagues – about large scale takeovers and lack of a locally owned company with global grain capacity.

    “There is still CBH in WA – a co-operative that is doing very well and is very strong,” he said.

    “But on the eastern part of the continent there will not be a major Australian player of global consequence active in the grain industry.

    “We lost the AWB, which was a world standard and an active participant in the world grain trade.

    “GrainCorp was the next thing we had to that and now there is a risk that could be taken over by a US grain trading company.”

    Senator Nash – who runs a grain producing business at Young in NSW – said she opposed the GrainCorp sale because it wasn’t in the national interest and current laws around foreign investment in agricultural land and assets are too weak.

    Speaking to Fairfax Agricultural Media, she said GrainCorp was the largest agribusiness in Australia, with around 280 grain receival sites and the most east coast port facilities.

    “It has a virtual monopoly on the grain handling logistics in the eastern seaboard,” she said.

    “I don’t believe it’s in the best interests of grain growers for the sale to go ahead.

    “It might be good for shareholders but I don’t believe it is good for growers and they are my priority.”

    Senator Nash has repeatedly spoken out on foreign investment, amid fears there’s a non-strategic approach to issues concerning national food security and agriculture’s role in meeting future export opportunities, in a food insecure world over the next 30 to 40 years.

    “We have an enormous opportunity in Australia to develop a strong future for our agricultural sector,” she said.

    “If we keep allowing foreign ownership of our agricultural businesses and land, the decisions for the future of agriculture will be taking place in boardrooms in other countries around the world.

    “We will potentially lose control of our future agricultural productive capacity.”

    Senator Nash said the strong support for conference motion showed the Nationals are “prepared to stand up for growers, the majority of whom I believe would not want the sale to go ahead”.

    “While foreign investment is a complicated issue, and we acknowledge some foreign investment is appropriate, it shows the Nationals believe this particular takeover is not in the nation’s interests or the growers’ interests,” she said.

    Asked if the Liberals would support the move, Senator Nash said, “You would have to ask the Liberals”.

    Senator Nash said the GrainCorp/ADM proposal may present a different challenge for Mr Swan, compared to the recent conditions he imposed on selling the iconic Queensland Cubbie Station irrigated cotton growing enterprise, to a Chinese consortium, with 20 percent Australian ownership.

    “I think it would be almost impossible to impose any conditions that would alleviate my concerns that this sale is not in the national interest,” Senator Nash said.

    “And I don’t have a lot of confidence in the current process to either require or enforce undertakings.”

    Senator Nash said she had little faith in the Foreign Investment Review Board (FIRB) deciding the best outcome, in the interest of Australia’s grain industry.

    “The FIRB has never rejected a foreign takeover of Australian land or agribusiness,” she said.

    “Unfortunately the Treasurer tends to back FIRB’s recommendations to allow our agricultural assets to fall into foreign hands.

    “He may dismiss the Nationals sentiments on the takeover but he has an obligation to act in the interest of Australian agriculture and I strongly urge him to do so.”

    Senator Nash said the Coalition, if elected to government, would ensure better scrutiny of foreign ownership in agriculture including adopting a national register of foreign ownership of farm land and agribusiness.

    She said they’d also ask the FIRB to review any proposed acquisition of agricultural land valued at $15 million or more; review any proposed foreign acquisition where the investment represents 15 per cent or more in an agribusiness valued at $244 million, or exceeds $53 million, whichever is smaller; and broadening FIRB membership to seven including people with agricultural and business expertise.

    In a recent speech in the House of Representatives, Mr McCormack said the takeover of GrainCorp wasn’t in the national interest should be rejected “out of hand” by the Treasurer.

    He called on Mr Swan replicate his move in 2011 where he rejected the proposed Singaporean takeover of the Australian Securities Exchange (ASX) saying it wasn’t in the national interest.

    “If such a buyer does not fail the national interest test, then I would ask: what does?” he said.

    Mr Truss dismissed suggestions his views may be at odds with the Liberals.

    He said is commentary on the party’s commitments FIRB reforms were the result of a long process with public submissions and a public paper.

    “I’m leader of The Nationals and I make my own calls on these things,” he said.

    The Senate Rural and Regional Affairs and Transport References Committee will also hold a brief inquiry into the proposed GrainCorp take-over bid; due to report by 31 July 2013.

  • New Airbus A350 successfully completes test flight

    New Airbus A350 successfully completes test flight

    Updated Sat Jun 15, 2013 11:03am AEST

    Airbus’s new A350 plane has glided smoothly through its maiden flight, leaving company executives relieved and brimming with confidence for the battle with Boeing that lies ahead.

    Designed to help the European manufacturer catch up with its American rival in the market for long-haul, fuel-efficient planes, the new Airbus completed a faultless test flight from an airport close to the company’s headquarters in southern France.

    After just over four hours in the air, the new plane touched down to cheers from thousands of Airbus employees and aviation enthusiasts who had assembled to watch the landmark flight.

    “We were on time and everything went perfectly,” a relieved Airbus boss Fabrice Bregier said.

    The plane cruised past crowds on the ground at a height of just 100 metres before looping round against clear blue skies and coming in to land.

    Although the flight was only the first in an intensive year-long testing program, Airbus needed Friday’s showcase to pass off without any hiccups in order to maximise the potential for further orders at next week’s Paris Air Show.

    “I’m confident it will be a roaring success in the market,” declared Tom Enders, the chairman of Airbus’s parent company EADS.

    Peter Chandler, Airbus’s chief test pilot who was at the controls when the plane took off for the first time, said the plane had been “ready to fly and wanting to fly” since it left the final assembly line two weeks ago.

    “That was obvious this morning as it was clearly much happier in the air than it has been running down the runway and stopping all the time,” he said.

    Boeing expressed its congratulations to its rival. “A new airplane is a very complex endeavour and this is a milestone the industry can celebrate together,” it said.

    Much like its competitor – Boeing’s new 787 Dreamliner, in service since September 2011 – the A350 makes extensive use of light composite materials that significantly reduce fuel consumption and costs.

    Airbus engineers celebrate ‘smoother and quieter’ flight

    Arnaud Verneau, one of the flight engineers on board on Friday, said the flight had been smoother and quieter than anyone had hoped for.

    “We were even able to put it on auto pilot on after two hours, which we had not anticipated doing,” he said, adding that the plane’s lighter materials had not resulted in more noise inside the cabin.

    “We will see as the tests progress but for the moment, it is the same (as a traditionally constructed plane),” he said.

    More than 10,000 hours of ground tests had been done on the airliner before the flight, and over the next year five test planes will criss-cross the globe in the warmest and coldest regions, at low and high speed.

    If all goes well, first delivery is expected at the end of 2014.

    Confirmed customers so far include Qatar Airways, British Airways and Hong Kong’s Cathay Pacific.

  • Google unveils Project Loon, aims to use balloons to provide internet to the world

    (Should this seemingly ridiculous Proposal work, there will no need for the ill- fated NBN rollout.)

     

    Google unveils Project Loon, aims to use balloons to provide internet to the world

    Updated 3 hours 22 minutes ago

    Internet giant Google has launched an ambitious plan to use a ring of huge balloons to provide internet to the two-thirds of the world currently without web access.

    The experiment, codenamed Project Loon, was trialled today at Christchurch, on New Zealand’s South Island.

    Scientists floated 30 helium-filled balloons around 20 kilometres into the stratosphere, carrying antennae linked to ground base stations.

    Wi-fi signals were beamed from another part of New Zealand to the 15-metre-diameter balloons, and then to the homes of about 50 trial participants.

    Google says the participants were then able to successfully link to the internet.

    While still in the early stages, Project Loon leader Richard DeVaul says the technology could increase internet access to countries such as Africa, and in South-East Asia.

    “About 4.8 billion people don’t have the internet right now,” he said.

    “Some of them are living in remote places, but some of them are actually living right here in New Zealand, and we think that Project Loon can play a big role in connecting many of those unconnected people.”

     

    Project Loon works by ground stations connecting to the local internet infrastructure and beaming signals to the balloons, which are self-powered by solar panels.

    The balloons, which once in the stratosphere will be twice as high as commercial airliners and barely visible to the naked eye, are then able to communicate with each other, forming a mesh network in the sky.

    Users below have internet antennae they attach the side of their house which can send and receive data signals from the balloons passing overhead.

    Google’s ultimate goal is to have a ring of balloons circling the Earth, ensuring there is no part of the globe that cannot access the internet.

    It has not said how much it is investing in the project.

    “The idea may sound a bit crazy – and that’s part of the reason we’re calling it Project Loon – but there’s solid science behind it,” Google said in a statement.

    How does it work?

    • Ground stations connect to the local internet infrastructure.
    • They beam signals to the balloons, which are self-powered by solar panels.
    • The balloons are then able to communicate with each other.
    • They form a mesh network in the sky.
    • Users below have internet antennae they attach the side of their house.
    • The antennae can send and receive data signals from the balloons passing overhead.

     

    “Balloons, carried by the wind at altitudes twice as high as commercial planes, can beam Internet access to the ground at speeds similar to today’s 3G networks or faster.

    “It is very early days, but we think a ring of balloons, flying around the globe on the stratospheric winds, might be a way to provide affordable Internet access to rural, remote, and underserved areas down on earth below, or help after disasters, when existing communication infrastructure is affected.”

    Project Loon has been in development since mid-2011 by scientists at the Google X research lab, which has previously produced a driverless car and the Google Glass augmented reality spectacles.

    The design lab plans to trial the internet balloons, which can stay in the air for up to 100 days, in Australia by mid-2014.

    The Southern Hemisphere, specifically the 40th parallel south, has been chosen for the trial partly because of the stratospheric conditions, with the balloons movements controlled from the ground by harnessing winds and solar power.

    The only part of Australia on the 40th parallel is north Tasmania – so that appears the likely destination for the Australian trial.
