  • Leaked Climate Commission report calls on Australia to triple 2020 carbon emissions cuts target

    Leaked Climate Commission report calls on Australia to triple 2020 carbon emissions cuts target

    ABCUpdated August 2, 2013, 9:29 am

    The Government’s main advisory body on climate change says Australia should triple its 2020 target for cutting carbon emissions.

    A leaked report to the Government from the independent Climate Commission says Australia should aim to cut emissions by 15 per cent of 2000 levels by 2020.

    That is up from the 5 per cent figure agreed to as a target by both sides of politics.

    The report says the cuts should ramp up to 40 per cent cut by 2030, and 90 per cent by 2050.

    The Gillard government set a 2050 target of 80 per cent.

    The report was obtained by the ABC’s Radio National Breakfast, and is due to be handed to the Government in October.

    The Climate Commission was established as a scientific independent advisory body to aid the Government and Australians in decisions about climate change, international action on greenhouse gasses, and the economics of a carbon price.

    The associate director of the Australian National University’s Climate Law and Policy Centre, Andrew McIntosh, says a 15 per cent target is achievable.

    “Economy-wide, an increase from 5 per cent to 15 per cent will result in only a marginal increase in the economic cost,” he said.

    “If you go to 40 per cent it will be significantly more, but not the sort of thing that’s crushing, and we could do it without suffering a major loss in GDP growth and the other major macro-economic indicators.”

    The final recommendations and report from the Commission are due in April next year.

    Mr McIntosh says if the world wants to aim to limit average temperature increases to just two degrees Celsius, governments will have to agree limit output of carbon to 300 billion tonnes over the next 90 years.

    “Think of that as a big carbon cake,” he said. “Every person on the earth should get an equal slice of that.”

    “If you adopt that approach, the 15 per cent by 2020 and 90 per cent by 2050 results in every person in Australia on average getting at least double what someone from the developing world gets.

    “Assuming that all developing countries adopt a similar approach.”

    He says the Government must consider if it wants Australia to continue emitting much more carbon than fellow nations.

    “How can you justify that the average Australian ends up with twice the allocation at least as the average Indian, or the average Chinese person?

    “It’s not enough and we need to go higher (than 15 per cent) if we want to reach that two degree target.”

  • Politicians are powerless over Australia’s economy

    Politicians are powerless over Australia’s economy

    Posted Tue Jul 30, 2013 2:59pm AEST

    The fate of the Australian economy – the big ups and downs of the economic cycle – will be determined by global conditions, not domestic ones, writes Chris Berg.

    Australia is a very small country with a very open economy. These facts are sometimes easy to forget.

    No matter what they say during the upcoming election campaign, neither Kevin Rudd nor Tony Abbott will have much control over Australia’s economic fortunes in the next term of government.

    Wrapping up his National Press Club address earlier this month, Kevin Rudd said Labor governments “manage transitions … sketch the future … harness the energy and ambition of our people” and “put the changes in place that best secures our future.”

    Tony Abbott has used the same sort of hyperbole. A Coalition victory would immediately trigger prosperity.

    Such boldness is par for the course at election time. But it is a confidence trick.

    The fate of the Australian economy – the big ups and downs of the economic cycle – will be determined by global conditions, not domestic ones.

    No-one knows this better than the workers at Holden and Ford, for whom global exchange rates are more important than any subsidy or tariff our elected representatives can devise.

    This has always been so.

    A sudden increase in the cost of bank lending in London caused our first true depression – the largely forgotten Depression of the 1840s. We suffered along with the rest of the British Empire.

    Our better-remembered second depression occurred in the 1890s. What little modern Australians know of the Depression of the 1890s is perhaps the housing boom in Melbourne which preceded bank failures and unemployment.

    But the Australian episode is only part of a story that encompasses the near collapse of the London-based Barings Bank, sovereign debt crises in Latin America and the Mediterranean, a gold panic in New York, and a mining market collapse in South Africa. Our trouble – as traumatic as it was – was just one crisis among many.

    The Great Depression was even more clearly imported. No way were we going to avoid suffering from the stock market crash of October 1929 or the collapse of world trade.

    Historically our good times correspond with good times in the global economy too.

    We boomed in the 1950s and 1960s along with everyone else. We suffered stagflation in the 1970s along with everyone else.

    And the recession we had to have?

    Well, that recession had to be had by the United States, Canada, New Zealand, the United Kingdom, and Japan as well.

    This all makes sense. Australia is tiny. Overseas there are cities with more people than our entire country. We’re almost entirely dependent on imports for consumption and exports for economic growth. And we need foreign capital for investment. A small country highly integrated into the global economy is going to be very sensitive to international crises.

    Yet for each of these historical episodes there exists a cottage industry trying to explain the unique Australian factors that caused them. The 1840s Depression is blamed on problems in the Australian wool industry. The 1890s Depression is blamed on reckless Australian banks. The depth of the Great Depression in Australia is blamed on our obsession with balanced budgets.

    It goes on. We’ve all heard Paul Keating blamed for the recession of the early 1990s and John Howard credited for the subsequent growth.

    If there is growth or recession in the next term Abbott or Rudd will take the blame or credit. They probably won’t deserve either.

    In the past I’ve mentioned research that suggests political success is more about dumb luck than virtue or competence. In truth Rudd or Abbott will win government then cross their fingers.

    But political debate struggles with powerlessness. Voters like to assign blame and give credit for things that are actually outside any domestic politicians’ control.

    Kevin Rudd rightly points out the global financial crisis dumped a bucket on Labor’s first term. The policy agenda of any party would have been drowned out by the global consequences of America’s subprime collapse.

    But then he claims his decision to artificially stimulate the economy was responsible for Australia’s relative endurance.

    Not, for instance, Chinese demand for West Australian minerals.

    In other words, Rudd believes the disease was entirely foreign, but the cure was entirely domestic.

    Yet even if you are a card-carrying Keynesian – that is, you believe the government can and should spend more to boost the economy in a downturn – it is just as plausible that China’s enormous stimulus package in 2008 is responsible for our prosperity, rather than Labor’s smattering of insulation and community projects.

    Australia spent around $90 billion to stimulate its economy. Sounds like a lot? Well, China spent over half a trillion dollars. And nearly three quarters of that spending went towards the infrastructure whose raw materials we supply.

    Our politicians pretend they can steer the economy like a ship. But we have a very small ship and it’s a very big ocean. During an election, it pays to remember our economic future is determined by the wind, not the sails.

  • Federal Government to establish bank bailout fund with new levy

    Federal Government to establish bank bailout fund with new levy

    Updated 1 hour 37 minutes ago

    The Federal Government is expected to announce a new bank levy on lenders set to start in 2016 to help fund any future bailouts.

    The levy will start on January 1, 2016 and will be set at 0.05 per cent on deposits of up to $250,000.

    It is understood the levy will raise $733 million in its first 18 months.

    The money raised will go into a new Financial Stability Fund and will be used in the event of a bank collapse.

    Bank shares stumbled today amid speculation the Government was considering a levy and there is concern that the cost of the levy will be passed on to consumers.

    At the close of trade, shares in the Commonwealth Bank fell by 1.47 per cent, while ANZ lost 1.24 per cent and NAB 1.6 per cent.

    But Westpac recovered most of its big losses to finish down 0.6 per cent, just two cents at $30.87.

    This afternoon Treasurer Chris Bowen held talks with the Australian Banking Association and credit unions in Sydney to consult them on the idea of a deposit protection levy.

    Mr Bowen pointed to a report from the International Monetary Fund (IMF) which he says highlights a gap in Australia’s public policy when it comes to “provisioning for any potential bank or deposit-taking institution failure”.

    “I’ve been consulting with banks about how we make sure that there’s money set aside in the unfortunate and very unlikely event that a deposit-taking institution in Australia comes into difficulty,” he said.

    In its latest report, the Reserve Bank puts the total amount of domestic deposits at $1.8 trillion, with $600 billion of that accounting for household savings.

    Stability fund to appear as revenue

    The ABC has been told the Financial Stability Fund will appear as revenue in the budget, as the Government grapples with revenue shortfalls ahead of releasing its economic update.

    Finance Minister Penny Wong would not be drawn on whether the money raised would better off in a superannuation-like fund rather than appearing as revenue on the budget bottom line.

    “The Treasurer today has referenced the fact that the IMF and the RBA have put a view to the Government about the need for a fund to cover deposit protection, and the Treasurer has made clear he’s consulting on that,” she said.

    The anticipated budget update is expected as early as tomorrow, and it could clear the way for Prime Minister Kevin Rudd to make the trip to Government House and call the election.

    Today the Government also announced it would increase the tax on cigarettes in a move it said would help reduce the number of smokers while also providing revenue for the budget.

    From December 1, the tax on tobacco will rise by 12.5 per cent each year for four years, raising $5.3 billion over the forward estimates.

  • Polar Ecosystems Acutely Vulnerable to Sunlight-Driven Tipping Points

    Polar Ecosystems Acutely Vulnerable to Sunlight-Driven Tipping Points

    July 31, 2013 — Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor.


    Share This:

    The research by scientists at UNSW and the Australian Antarctic Division predicts that biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm.

    The study, Light-driven tipping points in polar ecosystems, will be published in the journal Global Change Biology.

    Dr Graeme Clark, of the UNSW School of Biological, Earth and Environmental Sciences, says the team’s research shows that polar ecosystems may be even more sensitive to climate change than previously thought.

    “Even a slight shift in the date of the annual sea-ice departure could cause a tipping point, leading to widespread ecosystem shifts. On the Antarctic coast this may cause unique, invertebrate-dominated communities that are adapted to the dark conditions to be replaced by algal beds, which thrive on light, significantly reducing biodiversity,” Dr Clark says.

    The invertebrates lost could include sponges, moss animals, sea squirts and worms. These animals perform important functions such as filtering of water and recycling of nutrients and provide a food source for fish and other creatures.

    “This is a prime example of the large-scale ecological impacts that humans can impose through global warming — even in places as remote as Antarctica,” says UNSW team member, Associate Professor Emma Johnston.

    “Our modelling shows that recent changes in ice and snow cover at the poles have already transformed the amount of light reaching large areas of the Arctic and Antarctic annually.”

    For the study, the team deployed light meters on the sea floor at seven sites near Casey Station in Antarctica, at depths of up to 10 metres. They used cameras to photograph the coast at midday every day for two and a half years, to determine sea-ice cover.

    They determined the growth rates of Antarctic algae in the lab in different light conditions, and conducted experiments in Antarctic waters to test the sensitivity of algae to available light. They also surveyed species living on sub-tidal boulders, to see how communities varied with ice cover.

    Tipping points are events where small changes in environmental conditions cause rapid and extensive ecological change.

    The amount of sunlight reaching the poles is highly dependent on the seasons because Earth’s tilt causes the sun to be above the horizon for considerably longer during summer than winter, and the lower solar angle during winter increases reflectance from the water surface.

    “Early melt that brings the date of sea-ice loss closer to midsummer will cause an exponential increase in the amount of sunlight reaching some areas per year,” says Dr Clark.

    Coastal American Cities Threatened By Sea-Level Rise

    Boston, Miami, New York and more than 1,700 other coastal American cities are facing a greater risk from rising sea levels than had previously been estimated.

    A new study published in the Proceedings of the National Academy of Sciences (PNAS) claims at least 316 American cities will one day be overtaken by the sea if pollution continues to grow as it has been. More than 1,400 other cities will be locked-in” by rising sea temperatures. The report doesn’t give an estimated date when these cities will see oceans and gulfs begin lapping at more of their shorelines, but it does claim large portions of California, Florida, Louisiana, New York, North Carolina and Texas will have 25 percent of their land mass threatened by the rising sea, should pollution continue on its current track. With “deep cuts” in air pollution, this number could shrink dramatically from a 23-foot rise in sea level in 2100 to seven feet.

    The paper uses the term “lock-in” to describe the amount of sea-level rise which has yet to happen and cannot be avoided. If reductions in pollution are made, the rising sea could be slowed some. The locked-in rate, however, is the amount the sea will rise despite these actions, and according to the published paper, the sea will rise another four feet in areas like Boston, Miami and New York.

    The study, conducted by an international team of scientists led by Benjamin Strauss of Climate Central concluded the sea will rise by 4.2 feet for every degree Fahrenheit increase in global warming due of carbon pollution. The team now say the level at which this pollution is being spewed into the air will cause the sea to rise about a foot per decade for many decades into the future. Using this math, Miami, Virginia Beach, Sacramento, Jacksonville and other threatened cities could have sea levels increase by four feet by 2053.

    “Even if we could just stop global emissions tomorrow on a dime, Fort Lauderdale, Miami Gardens, Hoboken, New Jersey will be under sea level,” explained Strauss to The Guardian.

    “Hundreds of American cities are already locked into watery futures and we are growing that group very rapidly. We are locking in hundreds more as we continue to emit carbon into the atmosphere.”

    Though countries are looking to make deep cuts to pollution levels in the coming years, Strauss says these may not be enough to stop the rising sea, noting lock-in levels may already be too high. After all, he notes, just because pollution is reduced the existing emissions continue to harm the environment. Even if emissions came to a full stop, the amount of greenhouse gases in the atmosphere will continue to affect sea levels. These gases trap more heat in the Earth’s atmosphere which lead to ice sheet melting in Antarctica and Greenland, which, in turn, leads to an increase in sea levels.

    This is the second study published in PNAS in July detailing the effects of pollution on sea level. In the previous study, researchers used computer models to combine the Earth’s early history with new data from four major contributors to sea level rise. These contributors include the expansion of the ocean due to warmer temperatures, melting glaciers and the melting of both the Antarctic and Greenland ice sheets. Here researchers found today’s greenhouse emissions will drive sea levels to climb higher for centuries to come.

  • Dawn of Carnivores Explains Animal Boom in Distant Past

    Dawn of Carnivores Explains Animal Boom in Distant Past

    Oxygen increase led to evolution explosion, reverse possible in future

    Newswise — A science team that includes researchers from Scripps Institution of Oceanography at UC San Diego has linked increasing oxygen levels and the rise and evolution of carnivores (meat eaters) as the force behind a broad explosion of animal species and body structures millions of years ago.

    Led by Erik Sperling of Harvard University, the scientists analyzed how low oxygen zones in modern oceans limit the abundance and types of carnivores to help lead them to the cause of the “Cambrian radiation,” a historic proliferation of animals 500-540 million years ago that resulted in the animal diversity seen today. The study is published in the July 29 early online edition of the Proceedings of the National Academy of Sciences.

    Although the cause of the influx of oxygen remains a matter a scientific controversy, Sperling called the Cambrian radiation that followed “the most significant evolutionary event in the history of animals.”

    “During the Cambrian period essentially every major animal body plan—from arthropods to mollusks to chordates, the phylum to which humans belong—appeared in the fossil record,” said Sperling, who is scheduled to join Scripps as a postdoctoral researcher through National Science Foundation support. The authors linked this proliferation of life to the evolution of carnivorous feeding modes, which require higher oxygen concentrations. Once oxygen increased, animals started consuming other animals, stimulating the Cambrian radiation through an escalatory predator-prey “arms race.”

    Lisa Levin, a professor of biological oceanography at Scripps, along with graduate student researcher Christina Frieder, contributed to the study by providing expertise on the fauna of the ocean’s low-oxygen zones, areas that have been increasing in recent decades due to a variety of factors. While the Cambrian radiation exploded with new species and diversification, Levin believes this study suggests the reverse may ensue as oxygen declines and oxygen minimum zones expand.

    “This paper uses modern oxygen gradients and their effects on marine worms to understand past evolutionary events” said Levin, director of Scripps’s Center for Marine Biodiversity and Conservation and a 1982 Scripps graduate. “However, the study of oxygen’s role in the past is also going to help us understand the effects of and manage for changes in ocean oxygen in the future.”

    As part of the research study, Sperling spent time at Scripps working with Levin and Frieder. He also participated in the San Diego Coastal Expedition (bit.ly/sdcoastex), a cruise led by Frieder aboard the Scripps/U.S. Navy research vessel Melville and funded by the UC Ship Funds program, which offers students unique access to at-sea training and research.

    In addition to Sperling, Frieder, and Levin, coauthors of the paper include Akkur Raman of Andhra University (India) and Peter Girguis and Andrew Knoll of Harvard. Funding for the study was provided by Ministry of Earth Sciences, New Delhi, Agouron Geobiology, the National Science Foundation, and NASA.
