  • Antarctica may heat up dramatically as ozone hole repairs, warn scientists

     

     

    But John Turner of the British Antarctic Survey said scientists are now “very confident” that the anomaly had caused by the ozone hole above Antarctica. “We knew that, when we took away this blanket of ozone, we would have more ultra-violet radiation. But we didn’t realise the extent to which it would change the atmospheric circulation of the Antarctic.”

     

    These changes in weather have increased winds in the Southern Ocean region and meant that a large part of the continent has remained relatively cool compared with the western peninsula. But because the the CFC gasses that caused the ozone hole now been banned, scientists expect the damage to repair itself within the next 50-60 years. By then the cooling effect will have faded out and Turner said the Antarctic would face the full effects of global warming. This means an increase in average air temperatures of around 3C and a reduction in sea ice by around a third.

     

    The biggest threat to the continent comes from warming seas. Robert Binschadler, a glaciologist at Nasa who monitors Antarctic ice sheets, said: “The heat in the ocean is getting underneath the floating ice shelves, these floating fringes of the ice sheet that are hundreds of metres thick. That warm water is melting the underside of the ice shelf, reducing the buttressing effect.” Thinning of the ice shelf at the fringes leads to glaciers moving more quickly.

     

    The retreat of ice from Antarctica has contributed around 10% to global sea-level rise in recent decades. “The danger is that this warmer water will get under these ice shelves and cause the ice streams to get faster and feed ice out into the ocean,” said Turner.

     

    Published by the Scientific Committee on Antarctic Research (SCAR), a coalition of international experts that coordinates international research in the region, the report has been published to give negotiators in Copenhagen the most up-to-date science available. “Everything is connected — Antarctica may be a long way away but it is an important part of the Earth’s system,” said Colin Summerhayes, executive director of SCAR. “It contains 90% of the world’s ice, 70% of the world’s fresh water and that is enough, if it melts, to raise sea levels by 63m.”

     

    SCAR’s review also corroborated recent work by Stefan Rahmstorf, a climate scientist at the Potsdam Institute for Climate Impacts Research in Germany, that average sea-level rise will be closer to 1.4m by the end of the century. This is higher than the rise predicted by the Intergovernmental Panel on Climate Change (IPCC) in 2007, said Turner, because the IPCC’s forecasts did not include the impact of melting ice sheets on sea level rises. Many of the climate models used by the IPCC have also not taken the ozone hole into account in their simulations.

  • Feed-in tariffs in danger of being watered down

    Feed-in tariffs in danger of being watered down

    Ecologist

    30th November, 2009

    Campaigners say the Government is underestimating the potential of small-scale renewable electricity generation in the UK

    The UK could generate 6 per cent of its electricity from feed-in tariffs with minimal additional cost to household energy bills, say campaigners.

    According to the Government’s own figures, doubling the annual return on offer for small-scale renewable energy producers would add just £2.37 a year to household bills.

    The returns are part of proposals to incentivise renewable energy production. So called feed-in-tariffs, due to be introduced by April 2010, will pay households and businesses an above-market rate for every unit of electricity they generate and feed back to the national grid.

    Germany’s success

    Germany in particular has had significant success with feed-in-tariffs with more than 130,000 homes being fitted with solar panels every year.

    Friends of the Earth has criticised the current proposals on offer from the Department for Energy and Climate Change (DECC) for only aiming to generate 2 per cent of UK electricity from small-scale renewable technologies by 2020.

    DECC research

    The group says DECC is ignoring the results of its own research that showed setting the feed-in-tariffs to deliver a 10 per cent annual return on investment instead of the 5-8 per cent currently proposed would triple the Government’s current 2 per cent target.

    It would also add an average of £2.37 per year to household electricity bills over the next four years – just £1.20 a year more than the addition currently proposed.

    Kick-start

    A coalition of groups, including the TUC, British Retail Consortium and Federation of Small Businesses have written to MPs urging them to support calls for DECC to improve the incentives for renewable electricity generation.

    ‘A tiny addition to UK electricity bills would kick-start a world class scheme that would allow homes, businesses and communities to play their part in tackling climate change, increasing energy security and creating thousands of new green jobs,’ said Friends of the Earth’s energy campaigner Dave Timms.

    ‘The UK’s renewable energy potential is enormous. As the world prepares for crucial climate talks in Copenhagen, the Government must show that it is taking this issue seriously and improve its plans to pay people for generating their own clean, green power.’

    DECC said it will make a decision on feed-in tariffs early next year, ahead of its own deadline for introducing them of April 2010.

  • Copenhagen climate conference: Emission impossible

     

    Given what is at stake, essentially the future peace and prosperity of the planet, world leaders must now recognise that Copenhagen is the most important international gathering of our time. A strong political agreement can and must be reached in Copenhagen. There can be no excuses for failure.

    Recent weeks and months have shown country after country raising their ambitions on controlling emissions. It is now clear that if countries move together and they find ways to extend their action we could set the world on a responsible path. We can now see that it is possible to achieve an agreement that is effective, efficient and equitable. It will allow us to avoid the biggest risks of climate change, to overcome poverty worldwide and to usher in an exciting new era of prosperity based on a much more attractive and stronger form of economic growth – sustainable low-carbon growth.

    Through innovation and investment in greener and more energy efficient technologies in the next two or three decades, the transition to the low-carbon economy can be the most dynamic period of growth in economic history. And the low-carbon world we can create will also be quieter, cleaner, more energy-secure and more biologically diverse.

    For this to happen, there is a fierce urgency for leadership. The developed world in particular must face up to its responsibilities on both development and climate change. It will require radical change and significant resources. I believe we are now seeing strong momentum towards an agreement. Increasingly ambitions are being raised and shared. The developing world, if the rich world plays its part, will accelerate its actions and we can create an international collaboration which can transform the way the world works together.

    Three issues hold the key to agreeing an effective and equitable framework in Copenhagen. First, to have a reasonable – around 50% – chance of avoiding an increase in global average temperature of more than 2C above preindustrial levels, we must reduce annual worldwide emissions from the present level of just under 50bn tonnes of carbon-dioxide-equivalent to 44bn tonnes in 2020, much less than 35bn tonnes in 2030 and well below 20bn tonnes by 2050 – or as sometimes expressed, at least 50% below 1990 levels.

    Second, the need for national targets both to add up and to be fair means that the European Union, Japan and the US, should achieve emissions reductions of at least 80% by 2050, compared with 1990. Developing countries, including China and India, also need to limit the growth of, and then start to decrease, their emissions, but in ways that are consistent with their ambitions for continued economic growth and the reduction of poverty.

    Third, given the relative wealth of rich and poor countries, the rich countries responsibility for the bulk of past emissions, and the urgent need for action, developing countries must receive reliable and substantial support from the rich nations for their climate action plans. This is necessary both for their plans to reduce emissions and also to overcome the additional challenges that climate change will pose for their efforts to tackle poverty.

    Developed countries should show the extent of their commitment by providing $50bn per year by 2015, rising to $100bn in 2020, and progressing to around $200bn during the 2020s as effective low-carbon and adaptation programmes are developed and implemented.

    Crucially, financial support should be additional, beyond existing official development assistance. While these might sound like large sums, $50bn is around 0.1% of the likely gross domestic product of the rich countries in 2015, and is very small compared to the costs we will face if we do not secure a strong international agreement to tackle climate change. The immediate priorities for spending should be halting deforestation, supporting adaptation in Africa and other vulnerable nations, and supporting technological change throughout the developing world.

    We are seeking at Copenhagen an organisational framework with strong political commitment rather than a formal treaty. A formal treaty can follow in 2010 if the political framework is clear. But without such a framework, settled at the highest level, progress on a treaty or similar agreement will be impossible. Now is the time for heads of government to take charge – only they can forge such an agreement.

    Let us not allow mistrust, pessimism and lack of ambition to take us stumbling into profound dangers. Instead let us have real vision and leadership in both developing and developed countries which seize the opportunities offered by Copenhagen, for us, our children and future generations.

    George Monbiot

    “To be truly radical,” Raymond Williams wrote, “is to make hope possible rather than despair convincing”.

    Believe me I’m trying, but at the moment hope is hard to come by.

    A legally binding deal cannot now be struck at Copenhagen. The best that can happen is an outline agreement, which is firmed up next year. Even this would depend on the compliance of the US Senate. So far it has been hostile towards anything resembling an effective deal. As I write, Barack Obama still hasn’t proposed a number for US emissions cuts. He can’t make any firm commitment until the Senate sings, and the Senate won’t approve a climate change bill until the spring, if at all. I concentrate on the role of the US not because it is the only obstacle to a strong climate agreement (you should see what Canada has been up to) but because it has so far done more than any other nation to prevent global action from taking place. The Kyoto negotiations in 1997 were comprehensively trashed by a US delegation led by Al Gore.

    The EU had proposed a 15% cut against 1990 emissions levels by 2010. The US ensured that this was knocked down to 5.2% by 2012, with enough get-out clauses (emissions trading, joint implementation, the clean development mechanism) to render even that feeble target pretty well meaningless. After wrecking the treaty for everyone else, the Clinton government failed to ratify it, and George Bush later pulled out altogether.

    It wasn’t Gore’s fault: the Senate had already voted 95-0 to torpedo any treaty that failed to impose the same conditions on developing countries as it imposed on rich ones. The senators knew this was impossible for poorer countries to accept – in fact that was the point. The political impediments that made a deal with the US impossible in 1997 have scarcely changed.

    Until there is comprehensive campaign finance reform in the United States, almost any progressive measure remains out of reach. The US Senate is one of the most corrupt institutions of any democratic nation: most of the incumbents owe their seats to massive corporate funding; in return they must deliver the political goods to their sponsors. These are hopeless conditions in which to broker an agreement which has to defeat vested interests.

    Even if a legally binding treaty were to have been agreed at Copenhagen, getting it ratified and implemented before the Kyoto protocol runs out at the end of 2012 would have been a stretch. If it’s delayed until next year or beyond, the timetable becomes extremely tight. If world leaders can’t strike a deal this year, despite a massive build-up and intensive diplomatic activity, why should we expect them to be able to do so next year?

    I fear that the climate negotiations could go the same way as the Doha round of trade talks. These began in 2001. Eight years later there’s still no prospect of resolution. When the initial deadline had been missed and the red carpets were rolled up, governments lost interest and let the process drift. Delegates are already talking of moving the climate talks to Mexico next December after they fail in Copenhagen.

    This is what happened at Doha: the negotiations were reconvened at Cancún on the Mexican coast and vanished into thin air thereafter. Is “moving to Mexico” a diplomatic euphemism for abandonment?

    And there’s a more important deadline which looks ever more likely to be missed. The narrow window in which we could prevent more than 2C of global warming is closing fast. The longer a comprehensive agreement is delayed, the steeper the emissions cuts will have to be if we are to avoid climate breakdown. Beyond a certain point the scale of the cuts becomes politically, economically and technologically infeasible. That point must already be close.

    The postponement has an immediate consequence: no one will invest in low-carbon technologies unless they believe there’s a secure market. And no one will disinvest from fossil fuels unless they believe that they’ll cease to be profitable. If investors think the Kyoto protocol will run out before a new agreement begins, the bottom will fall out of the market for energy conservation and alternative technologies, setting the necessary transition back by years.

    So is there any hope that world leaders could regain their sense of urgency? If the prospect of a climate crash doesn’t motivate them, can anything? Perhaps there is one straw to cling to. In its new World Energy Outlook, the International Energy Agency (IEA) maintains that, to meet new demand and replace old equipment and exhausted reserves, the world will have to invest $25.6tn in energy supply infrastructure between now and 2030. The industrialised nations would also need to pay a fortune to the Opec countries to maintain their oil and gas supplies: the IEA predicts that the oil producers’ income will rise fivefold in this period, to $30tn. These costs will be much higher if oil supplies peak.

    If moving to a low-carbon economy looks implausible, so does maintaining the high-carbon economy. Whichever route is taken, staggering amounts of money need to be spent. As resources become harder to extract and concentrated in fewer countries, it shouldn’t be too difficult to persuade world leaders that the money might as well be spent on exploiting ambient energy, which will neither run out nor allow us to be held to ransom.

    That is the best I can do. Sorry.

  • Carbon trading could be worth twice that of oil in next decade

     

    The ETS market may see $3tn (£1.8tn) worth of transactions a year in the next decade or two, according to Andrew Ager, head of emissions trading at Bache Commodities in London, with it even being used as a hedge against falling equities or rising inflation. “It is still a relatively new industry with annual trades of around €300bn every year. But this could grow to around $3tn compared to the $1.5tn market there is for oil,” says Ager, who used to be a foreign currencies trader.

    The speed of that growth will depend on whether the Copenhagen summit gives a go-ahead for a low-carbon economy, but Ager says whatever happens schemes such as the ETS will expand around the globe.

    Last week Australia gave its strongest sign yet that it would establish its own trading market, while the US is moving towards a similar scheme in a bid to find market-based ways to accelerate the transition to a lower carbon economy. 

    Many political leaders, especially in industrialised countries, are enthusiastic: carbon markets hold the promise of cost-efficient emission cuts without the need for taxpayer funding. But their enthusiasm to place carbon markets at the heart of the Copenhagen treaty is matched by growing criticism of the concept, and not just from environmentalists opposed to free market solutions.

    Peter Voser, Shell’s chief executive, has called on governments to introduce a carbon tax or a minimum price for CO² because – as he told the Guardian – the ETS was failing to deliver sufficient incentives to kickstart expensive technologies such as carbon capture and storage (CCS).

    John Browne, a former boss of BP and an early ETS promoter, has also expressed reservations about such schemes, saying it was “wrong” to place all your faith in them. Vincent de Rivaz, chief executive of EDF Energy, warned of the dangers of a “sub-prime” crisis inside the ETS if complex financial instruments were created by market participants.

    The key problem seems to be that ETS carbon prices have remained resolutely low, thwarting low-carbon, high-cost investment. Carbon is currently trading at around $13 a tonne but many believe it needs to be $30, if not $50, to deliver a decisive boost for clean technologies such as wind, solar, CCS and nuclear power.

    The criticisms of environmentalists such as James Lovelock and Friends of the Earth (FoE) are far more fundamental. The basic charge is that the market has put millions of pounds into the pockets of some without making any real impact on carbon emissions.

    They accuse governments of being too lenient in the way they drew up the ETS: a cap that was far too loose, too many free permits, too few industries covered and poor monitoring of offset schemes that shift emissions to the developing world. If the carbon price is to rise in the next ETS phase, starting in 2013, much tighter rules will be needed.

    Henrik Hasselknippe, senior analyst at consultancy Point Carbon, argues the problems have been overplayed and the market – while not operating perfectly – has nonetheless come along way from a standing start.

    “Carbon prices have fallen due to the recession,” said Hasselknippe, adding that he was “convinced” that CDMs – clean development mechanism credits created under the Kyoto protocol – have led to real carbon reductions. However, some reports claim that a third to two-thirds of CDMs do not reduce emissions.

    Alexandria Galin, a policy manager for the Carbon Markets and Investors Association, dismisses suggestions that the market had been taken over by speculators, as claimed by FoE. “Financial institutions participate in the market largely on behalf of businesses that do not have the capacity or expertise to do it themselves. Furthermore there are no ‘complex’ instruments creating ‘shadow finance’,” she said.

    Agers agrees, saying his company largely provides advice or trading on behalf of power companies and others who need to hedge their legitimate carbon risks.

    He admitted that he is in many ways like any other City trader with a decent salary, nice flat and sports car to prove it. But working in the carbon field has rubbed off a little on his lifestyle: he claims to have energy-efficient lightbulbs in his home and to offset the petrol he uses driving his car to watch West Ham football team on a Saturday.

    The arguments

    Carbon market

    For

    • Guarantees specific carbon cut by setting overall cap

    • Delivers maximum cuts in carbon emissions at minimum cost

    • No taxpayer funding

    Against

    • Volatile or low price of permits deters investment

    • Prone to political interference, complex and provides no incentive for individuals to act

    Carbon taxes

    For

    • Clear, simple, covers everyone

    • Relatively low implementation costs

    Against

    • Hits motoring and flying directly

    • Cannot deliver specific emissions cut – depends on consumption levels

    Regulation

    For

    • Cannot be avoided by finding loopholes

    • Can drive big changes where markets cannot, such as energy efficiency

    Against

    • Businesses rail against red tape

    • Expensive to implement

  • FOOTPRINTS

     

    Agreeing to end fossil fuels wont work if we leave it until 2020. We need to cut all use by 10 percent every year until then. The men of money have sown doubts among us, with an exceptional attack on the integrity of the scientific community.

    Why do we listen to them? George Monbiot suggests that denial is our habitual way of dealing with fear of death. This is like saying “We all know we are doomed if we do nothing. Yet we are too comfortable as we are. Lets roll over and go back to sleep, maybe it will just pass away!” Fat chance!

    So, back to the present: Copenhagen. The summit is political. This means compromise between opposing forces. As in vector analysis, the resultant will be in between, which means significantly less than is needed.

    There is no point in targeting politicians without also targeting the decision-making individuals who are hiding behind their corporate facades. To expect politicians to make decisions is pointless. We need to project ourselves directly onto the other force in the vector, on a personal basis.

    Two million Australians will become sea-level refugees. How many of them run the companies causing the problem? This is where action should be directed.

  • Western lifestyle unsustainable, says climate expert Rajenda Pachauri

     

    “Today we have reached the point where consumption and people’s desire to consume has grown out of proportion,” said Pachauri. “The reality is that our lifestyles are unsustainable.”

    Among the proposals highlighted by Pachauri were the suggestion that hotel guests should be made responsible for their energy use. “I don’t see why you couldn’t have a meter in the room to register your energy consumption from air-conditioning or heating and you should be charged for that,” he said. “By bringing about changes of this kind, you could really ensure that people start becoming accountable for their actions.”

    Pachauri also proposed that governments use taxes on aviation to provide heavy subsidies for other forms of transport. “We should make sure there is a huge difference between the cost of flying and taking the train,” he said. Despite the fact that there is often little benefit in time and convenience in short-haul flights, he said people were still making the “irrational” choice to fly. Taxation should be used to discourage them.

    He dismissed suggestions that the actions he was advocating were insignificant next to the decisions that would be made at the UN’s climate summit which opens in Copenhagen in seven days’ time. “In a democracy, governments will ultimately respond to what the people want,” he said. “If the people have a strong desire which can be demonstrated through their actions, as well as their vote at the time of elections, you can bring about a major shift in policy.”

    Pachauri caused controversy last year by advocating, in an interview with the Observer, that people should eat less meat because of the levels of carbon emissions associated with rearing livestock. He is scheduled to deliver a keynote speech at the opening session of the Copenhagen summit.

    He said the opening bids from China and the US on emissions – announced last week – had given hope that a deal could be reached in Copenhagen, even if some details would have to be filled in later. “I think it provides momentum to the whole negotiations,” he said.

    Pachauri was speaking to the Observer before a public discussion at the Wellcome Collection in Euston with the philosopher AC Grayling yesterday. It will be broadcast by the BBC World Service on Wednesday.

    He said that he also believed car use would have to be “curbed”: “I think we can certainly use pricing to regulate the use of private vehicles.” He added he was a supporter of former London mayor Ken Livingstone‘s plan to increase the congestion charge to £25 for the most polluting vehicles. The proposal was dropped by Boris Johnson and the charge currently stands at £8. Pachauri also denounced the practice in some restaurants of providing iced water to customers who had not ordered it. “It is just an enormous amount of waste that we don’t even think about,” he said.

    Ultimately, Pachauri said the value shift that was needed would take a generation to take hold. “I think the section of society that will make it happen is essentially young people. I think they will be far more sensitive than adults, who have been corrupted by the ways we have been following for years now.”
