Posted on Sustainabilitank.info on March 4th, 2009 EU ministers shirk third-world climate finance. Poorer countries have been left hanging by EU environment ministers, who at a meeting in Brussels failed to produce any clear funding commitments to help the developing world tackle climate change.
“It makes no sense to say now how much the EU is willing to transfer,” German environment minister Sigmar Gabriel said at a press conference after the meeting. “We were not quite able to reach consensus on the financing mechanism. This is an issue where the [European] Council will need more discussion time,” said EU environment Commissioner Stavros Dimas, also in attendance at the ministers’ meeting. But because the EU also wants developing countries, particularly emerging nations such as China, India, Brazil, Mexico and Indonesia, to also commit to reductions, climate finance for the third world has become the main focus of discussion in the lead-up to the Copenhagen meeting.
However, despite the speed with which the EU and US found €2.6 trillion to bail out financial institutions over the course of 2008, coming up with funds for third-world climate measures is now proving much more elusive. Environment ministers did however endorse the sum that the commission had suggested in its January proposals would need to be spent by all countries around the world to combat climate change – roughly €175 billion annually by 2020, with half of that having to be invested in the developing world. –=–=–=– Paris vs. Warsaw The two issues of how much of that half would come from the EU and, crucially, how much from each EU member state are at the heart of debate between the ministers. According to the commission’s proposals, EU financing for the developing world would come either through an annual financial commitment on the basis of an agreed formula, or by a percentage of monies coming from revenues produced by the creation of a carbon market across all wealthy countries similar to Europe’s Emissions Trading Scheme (ETS). If the EU opts for the fixed commitments, the formula to share out the burden would involve a calculation based on a member state’s GDP, its emissions in comparison to GDP, and the size of its population. Paris wants added to this formula a consideration of the amount of emissions per capita. France likes this idea because it has the lowest emissions per capita in the EU. Poland, meanwhile, is not such a great fan because of its dependence on coal, an extremely dirty source of energy. Green groups and development agencies said they were getting impatient with the EU on the question of climate finance. Oxfam meanwhile said that delaying commitments for climate finance in poor countries puts any “global climate deal at risk”. “The EU needs to put money on the table now. Treating poor people’s lives as a bargaining tool in climate negotiations is both immoral and misguided as a negotiating strategy,” said Katia Maia, with Oxfam in Brazil.
The EU itself is committed to cutting its own carbon emissions by 20 percent by 2020 on 1990 levels, or 30 percent if other developed nations agree to a similar cut, although the UN’s Intergovernmental Panel on Climate Change (IPCC) 2007 recommendations say wealthy nations must cut emissions by between 25 and 40 percent by 2020 if dangerous consequences for humanity and the environment are to be avoided. Last month, Chris Field, a leading climate scientist with the IPCC, warned the 2007 predictions – upon which EU policy is based – are far too optimistic, meaning that CO2 reductions of 25-40 percent by 2020 are insufficient. At the same time, many of those reductions committed to by the EU will not really be performed domestically, as a large chunk of the 20 or 30 percent will come from so-called carbon offsets – essentially where wealthy countries pay poorer ones to make their carbon cuts for them. ### |

Posted on Sustainabilitank.info on March 2nd, 2009 The Big Question: Officially, this is the first day of spring. So why does it feel like midwinter? The Independent of London, Wednesday, 21 March 2007. Why are we asking this question now? As you may have noticed, it’s been cold outside. And the simple answer to the big question at the top of the page is that one swallow does not make a summer. In other words, the weather and the climate are not the same thing, although they are of course related. One is what you get on a day-to-day basis, the other is a long-term trend over many decades, centuries or even millennia. The current cold spell is due to cold winds streaming down from the frozen Arctic, which is not an unusual event for Britain at this time of year. Global warming does not mean an end to spells of cold weather in winter, but it does make them less likely over time. The computer models of global warming predict that as average worldwide temperatures rise, there will be an increase in the chances of warmer, wetter weather in winter and hotter, drier spells in summer. Where does ‘weather’ end and ‘climate’ begin? There is no strict point when one becomes the other – it is purely a question of time. Climate is something that can be defined over hundreds or even thousands of years. As a spokesman for the Met Office said: “It would be fair to say the weather becomes climate when observations of the weather are long enough to glean a trend from those records.” For the past 100,000 years or so the Earth has experienced fairly regular swings in climate from freezing ice ages to warmer periods of “interglacial” temperatures. We are currently living in a warm, interglacial period, which began at the end of the last ice age about 10,000 years ago. It is no coincidence that this was the time when we invented agriculture, which led to the rise of civilisation. We can expect another ice age in a few thousand years, all other things being equal, although current man-made global warming could affect the timing of that fairly inevitable event. Ice ages appear to be triggered by small changes to the angle of the Earth’s tilt in its orbit around the Sun. On a shorter timescale, the weather patterns in any geographic region can be described in terms of that region’s local climate. Britain, for instance, has a maritime climate where the seasonal variations are not as extreme as in areas affected by continental air masses, such as central-southern Siberia which is on about the same latitude as Britain yet experiences far colder winters and hotter summers. Nevertheless, the mild maritime climate of north-west Europe can be interrupted occasionally by incursions of cold Arctic air in winter – which is happening now – and hot subtropical air in summer. How do we know the climate is changing? This is the key to our understanding of climate change. Being able to discern long-term trends in the apparently random “noise” of day-to-day variations lies at the heart of understanding the scale of global warming. Essentially, scientists believe that the climate is changing for many reasons but one of the most important is the fact that long-term weather records suggest it is happening. Different countries have gathered records on many different phenomena related to the weather and these individual measurements can be collated and analysed to give a bigger picture of how the weather – and climate – have changed over time. Good records of course depend on sound instruments and expert monitoring. The longest accurate series of monthly temperatures, for instance, is the Central England Temperature records. These cover a triangular area between Liverpool, Bristol and London with the monthly series of temperatures beginning in 1659 – the oldest continuous temperature record anywhere in the world. This temperature record shows that the hottest years in the sequence were 1990 and 1999 – with an average annual temperature of 10.63C – and the hottest ever year was 2006, with an average annual temperature of 10.84C. The coldest year was 1740 and the hottest month was July 2006. But aren’t we seeing more flowers in winter? One of the most interesting ways of looking at the results of long-term climate is called “phenology”, which is the study of recurring natural phenomena such as the flowering of the first daffodils in a garden, the appearance of the first migratory bird or the times of ripening of autumn fruits. According to the Woodland Trust, spring in Britain is coming about two weeks earlier than it would have been about 30 or 50 years ago and autumn is arriving about a week later. Many amateur naturalists can now observe the sort of changes that would be expected if the climate were altering as a result of global warming. What about birds and animals? There can be real problems for animals and birds that have been lured into breeding earlier than normal. A warmer-than-average winter, such as we have seen this year, may tempt birds and animals into having their young weeks earlier than they generally would. Then, if the cold returns, the nestlings and the young animals are suddenly very vulnerable, and may die. We have seen this happening recently in southern England, with baby squirrels, baby hedgehogs, even baby grass snakes being found in distress and taken to animal refuges like the St Tiggywinkles wildlife hospital near Aylesbury in Buckinghamshire. Will it get worse? It may do, if the weather and wildlife breeding patterns increasingly get out of sync. This year and indeed in previous years there have been warm spells followed by cold snaps which have hit wildlife hard locally and temporarily, but this has been a merely passing phenomenon. It is possible that it could become more systematic and more serious. For example, many woodland birds feed their young on caterpillars and time their nesting to coincide with the caterpillars’ appearance. If they appear earlier, resident birds will learn to adapt, but migratory species may arrive in Britain too late for the major food source for their chicks – and their populations may crash as a result. Has too much been made of particular dramatic events? Some people claim that, for example, the flooding of New Orleans by Hurricane Katrina in 2005 was caused by global warming; but others say that such events, although rare, are not unknown in the Gulf of Mexico. Others warn that while no one event can be ascribed to global warming, it is the trend that is to be feared. Although it may well be that there are more frequent weather shocks than previously, we just cannot know which of them is caused by global warming and which would have happened anyway. Should we be surprised by unexpected cold spells? Yes… * People have come to think that because global warming is a fact, it must always be warmer than we remember * As the winters are becoming warmer, it goes against expectation that the early spring suddenly turn cold * If the Arctic is warming up, one would not think that winds from this region would be so cold at this time of the year No… * Natural variability means that the temperature is always going to oscillate over the short term * What we are seeing here is day-to-day weather, whereas climate change occurs over longer periods * The turning point between winter and spring is usually a period of unsettled weather ### |

Credit:Photo Stock BOSTON, Dec 31 (Tierramérica) – Warm ocean currents may have confused some 2,500 penguins from Argentina’s Patagonia region that washed up — dead and alive — on Brazil’s northern coast. About half the penguins that were found on Brazilian beaches in October were dead, and the others were starving and in very bad shape, said Valeria Ruoppolo, an emergency veterinarian with the International Federation for Animal Welfare (IFAW), in Sao Paulo, who coordinated the rescue of many of the penguins. “Of the live ones, about 50 percent survived,” Ruoppolo told Tierramérica. Magellan penguins (Spheniscus magellanicus) live in relatively warmer climates than other penguin species, and breed and nest in burrows in the southern hemisphere spring and summer, from October to February, in southern Chile and Argentina, in a temperate and dry climate. They travel out to sea during the winter, from March to September, to follow anchovies, their favourite food, in order to fatten up. Juveniles also migrate north. This year, about 2,500 disoriented juvenile penguins traveled more than 2,500 kilometres beyond the normal point, coming ashore in Salvador, in Bahia state, 1,400 kilometres north of Sao Paulo, to the amazement of beachgoers. The penguins were rescued by IFAW and the Centre for Marine Animal Recovery, with help from other organisations and Brazilian environmental authorities. After months of care and feeding, the 372 surviving penguins were banded and loaded onto a C-130 Hercules military plane and transported to Cassino Beach, in Pelotas, in southern Brazil. After an overnight rest, they were released into the South Atlantic ocean, along with a few other rescued adult penguins, with the hope that they would guide the younger ones safely home to Patagonia. About 200 people cheered them on as they waded into the surf. It was the largest penguin rescue on record, a success for animal welfare experts — but a terrible omen for the penguin population. “We always have a few strandings here and there. In 1994 and 2000 we had big strandings. But not like this year. More than 2,000 penguins is unheard of,” Ruoppolo said. Magellans are one of 17 species of penguins, which all live in the southern hemisphere, including the Antarctic. Magellans are among the largest, weighing just over four kilograms, with striking colouring: a white chest and a white band around a black back and black head. The Magellan penguin population is fragile, as their numbers have plummeted by about 20 percent, with about one million breeding pairs today, according to the Wildlife Conservation Society. The penguins are at risk due to the effects of climate change, tourism, oil leaks from tankers and shrimp nets. “We are going to try and understand what happened,” using the identification bands as a tool, Ruoppolo said. Once the penguins reach their home colonies, volunteers and researchers there will notify Ruoppolo. She will aggregate data about the climate, ocean currents and food sources, to learn about the strandings. “One thing that was different is that the surface of the Atlantic ocean was one degree Celsius warmer. The penguins follow the fish, especially their favourite, the anchovies. Probably what happened this year is the anchovies went deeper into the ocean for the cold water. And the penguins couldn’t reach their food and they stranded because they were starving,” she said. However, Ruoppolo warned, “We don’t know yet if we can link the strandings to climate change. Soon we will be able to say.” According to Sybille Klenzendorf, a scientist with the World Wildlife Federation (WWF), “It’s probably not going to be unusual for some of these things to happen,” given the rise in temperature of the ocean. The ocean environment of the southern tip of Patagonia especially is undergoing alterations, Klenzendorf said. Due to glaciers melting, the salinity of the water there is changing. “The salt content is becoming less. It’s not just the temperature that is changing,” she told Tierramérica. WWF scientists recently warned that allowing the earth’s surface temperatures to rise an average 2 degrees Celsius further — which is expected within 50 years even with a reduction in greenhouse gas emissions — will severely endanger Emperor (Aptenodytes forsteri) and Adelie (Pygoscelis adeliae) penguins and other Antarctic wildlife. The current targets for reducing greenhouse emissions “aim at stabilising the climate at 2 degrees higher than it is today. But what we’re saying is we need to be more conservative than 2 degrees,” Klenzendorf said. Furthermore, stress from the ocean changes would exacerbate an already dwindling source of fish for the penguins, due to aggressive commercial fishing in the region, she said. During nesting season, male penguins are swimming further each day to feed, compared to their normal forays, according to P. Dee Boersma, a penguin expert at the University of Washington. Boersma, who has a research station in Punta Tombo, home to the largest colony of Magellan penguins, on the coast of the southern Argentine province of Chubut, says the changing climate has included more rain in recent years. Coastal Patagonia is normally very dry, and the increasing rains mean that wet penguin chicks die of exposure, Boersma says in research published recently in the journal BioScience. “Penguins are sentinels of the marine environment, and by observing and studying them, researchers can learn about the rate and nature of changes occurring in the southern oceans,” she says. Punta Tombo is a tiny peninsula near the city of Rawson. Its widest point is less than one kilometre, and it is teaming and crowded with penguins — and tourists — during breeding season. About 105,000 people visited the penguin colony in 2007. Local efforts are underway to protect the penguins from further encroachment. In 1982, the Punta Tombo colony was saved from Japanese commercial interests, which wanted to slaughter the birds and use their pelts to make golf gloves. The area was turned into a penguin preserve and research centre, led by Boersma. (*This story was originally published by Latin American newspapers that are part of the Tierramérica network.

Posted on Sustainabilitank.info on November 28th, 2008 The UNU on Arid Aquaculture. The UNU researchers issued a report “Arid Aquaculture Among Alternative Livelihoods Promoted to Relieve Worsening Pressure on World’s Drylands” as a result of the four-year study in cooperation with the International Centre on Agricultural Research in Dryland Areas (ICARDA), and UNESCO’s Man and the Biosphere (MAB) Program. “Arid aquaculture” using ponds filled with salty, undrinkable water for fish production is one of several options experts have proven to be an effective potential alternative livelihood for people living in desertified parts of the world’s expanding drylands. While it may sound far-fetched, researchers say using briny water to establish aquaculture in a dry, degraded part of Pakistan not only introduced a new source of income, it helped improve nutrition through diet diversification. The researchers also showed it possible to cultivate some varieties of vegetables with the same type of brackish water. The project based on the results of the research will be launched by the project partners in Istanbul, Turkey, at 1:00 pm local time Nov. 12 at meetings of the UN Convention to Combat Desertification.

Posted on Sustainabilitank.info on November 17th, 2008 DLDD = Desertification, Land Degradation and Drought. The high-level policy dialogue (the “Dialogue”) on the theme “Coping with today’s global challenges in the context of the Strategy of the United Nations Convention to Combat Desertification” (UNCCD), took place on Tuesday, 27 May 2008, in Bonn, Germany. The Dialogue was intended to facilitate a targeted exchange from a number of stakeholders on the ten-year strategic plan (“the Strategy”) and to foster awareness of and buy-in among relevant policy and decision makers. There were over 120 participants, including ambassadors, ministers, country representatives, intergovernmental organizations, UN agencies, NGOs and the private sector. The Dialogue consisted of three segments, each of which comprised presentations and discussion among participants. Above as reported by IISD from the United Nations Convention to Combat Desertification (UNCCD) – UNCCD HIGH-LEVEL POLICY DIALOGUE in Linkages: www.iisd.ca/vol04/enb04208e.html Now We have a new PRESS RELEASE FROM A UNCCD Conference: Istanbul, Turkey, 14 November 2008 - A major United Nations conference ended today with significant steps taken to combat desertification and land degradation as well as to mitigate the effects of drought, known as DLDD. Delegates from the 193 countries who are the Parties to the United Nations Convention to Combat Desertification (UNCCD) took significant actions to resolve difficult scientific problems within the Convention process. By drawing in the scientific and technological community more intensively to create indicators that can be used at national levels and beyond, the Convention will win more confidence of the stakeholders. In addition, the reporting process from the Parties is to be mainstreamed so that both affected countries and development partners can see where the Convention reaps large benefits and retain them, while eliminating less effective ones. “The delegates here in Istanbul took a big stride to guide the next year’s ninth Conference of the Parties (COP9) [the decision making body of the Convention]. We are all on the same page. But it has to be remembered that without proper action by stakeholders, both in developing and developed countries, some 50 million people could be displaced by desertification and land degradation within the next ten years,” said Mr. Luc Gnacadja, Executive Secretary of the UNCCD. The Seventh Session of the Committee for the Review of the Implementation of the Convention (CRIC 7) and the first special session of the Committee on Science and Technology (CST-S1) were held in Istanbul from 3 to 14 November. At the first special session of the Committee for Science and Technology (CST-S1), the scientific advisory body of the Convention, delegates confirmed that promoting the participation of the national science and technology correspondents (STC) in the activities of the committee would enhance its work. The Committee, in consultation with STCs, is now moving forward to select a minimum set of indicators to measure the impact of the implementation of the Convention. Mr. Gnacadja said that these indicators would be applicable to all countries so that a common standard can make analysis at the national, sub-regional, regional, and the global level feasible. It will also increase the effectiveness of the implementation of the Convention. The set of indicators will be finalized during regional scientific meetings next year towards the submission to COP9. *** At the seventh session of the Committee for the Review of the Implementation of the Convention (CRIC 7), which followed the CST-S1, the delegates agreed on reporting principles which measures the Convention’s implementation progress. Through the reporting process, affected countries and development partners would understand “what works, what doesn’t” in implementing the Convention. Assessment of national capacity to implement the Convention will be conducted in all regions in order to design a comprehensive capacity building approach. The new reporting format will provide opportunities for affected country Parties to address their success and constraints in implementing the Convention in its 10-year strategic plan. For developed country Parties, future reporting should focus on providing information about how the Convention has been mainstreamed into their development cooperation strategies. Another significant step was the concrete proposal to strengthen the involvement of integration civil society organizations in the review process. “Recommendations made at the conference have several significant implications. First, the reporting guidelines will increase credibility of the Convention. Secondly, by Parties agreeing to the establishment of the workprogramme, taking a result-based management approach, the Convention will increase accountability. Further, the cooperation among the Convention institutions will increase efficiency of the implementation process of the Convention.” commented Mr. Gnacadja. “This is a certain step-forward for making the Convention a systemic and worldwide response to global environmental issues affecting land and its ecosystems.” The new recommendations would entail a wider use of the information generated by countries and would achieve a higher level of accountability as desired by the Parties, according to the UNCCD Executive Secretary. These will be addressed at the next Conference of the Parties in autumn 2009. “The pieces have fallen together here in Istanbul to fight DLDD. Now is the time to act,” concluded Mr. Gnacadja.

Posted on Sustainabilitank.info on November 13th, 2008 Carbon News and Info, Tuesday, 11 November 2008. The Maldives is a group of 1200 tropical islands in the Indian Ocean, 80 per cent of which are less than one metre above sea level. Much of the most inhabited parts of the country are just 1.5 metres above the water. The first democratically elected leader, Mohamed Nasheed, and his Vice-President, Mohamed Waheed Hassan Manik, wasted little time in declaring their plans to British newspapers saying a national fund would be established with royalties from the country’s tourist industry to fund land purchases. Nasheed told the Guardian that Sri Lanka and India were obvious targets given their proximity, and the cultural similarities of their people to the 300,000 Maldivians. He also named Australia as a possible destination. In 2005, authorities announced plans to move the 1000-strong population of the Carteret Atolls, in Papua New Guinea, to Bougainville in what were said to be the first climate change evacuations. Their current homes are predicted to become completely submerged by 2015. ### |

Posted on Sustainabilitank.info on November 12th, 2008 Science Proves Warming of Antarctica. By Adrianne Appel* BOSTON, Nov 12 (Tierramérica) – The Antarctic holds the world’s largest amount of fresh water in its icy grip, and it is most certainly warming as a result of greenhouse gases, say new scientific studies. “We’re able for the first time to directly attribute warming in both the Arctic and the Antarctic to human influences,” said Nathan Gillett of the University of East Anglia, in Britain, who led the study. Evidence of global warming, caused by the release of carbon dioxide and other pollutants into the air, has been found on almost every continent on Earth. The exception was the Antarctic, which holds 90 percent of the world’s ice and 70 percent of the world’s fresh water. Antarctica, about 1.4 times as large as the United States, has just 20 weather stations from which to gather data, and for this and other reasons, less has been known about the icy continent. Scientists can see that the warmer parts of Antarctica, including the Western Antarctic and Antarctic Peninsula, which juts north toward South America and is home to millions of seals and penguins and other birds, are seeing temperature increases. But the frigid East Antarctic, with ice 2,226 metres thick, has seen no significant change in air temperature during the past 50 years — in fact it has shown evidence of cooling — and this has made overall conclusions about the greenhouse gas effect inconclusive. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) concluded that Antarctica was the only continent where human-caused temperature changes had not been detected, possibly due to insufficient data and observation. Gillett’s work “demonstrates convincingly what previous studies have suggested: that humans have indeed contributed to warming in both the Arctic and Antarctic regions,” said Andrew Monaghan, of the U.S. National Centre for Atmospheric Research, a close colleague of the researchers. The team used all data available from 1900 to 2000 from the 20 research stations, and complex computer predictions to reach its conclusions. The scientists created four computer models, including one that included the impact of greenhouse gases and one that did not. The model with the greenhouse gases produced predictions that matched actual temperature observations up to this point in time, according to their report, “Attribution of polar warming to human influence”, in the scientific journal Nature Geoscience. Taking averages across all of Antarctica produced findings of “overall warming” of a few tenths of a percent, Gillett said. But the team found temperature increases on the Antarctic Peninsula of up to 3 degrees Celsius since the 1950s, among the largest increases on Earth, Monaghan said. Still, the average monthly temperature is 1 degree to minus -15 degrees C. Several large glaciers in the West Antarctic are melting and contributing to a rise in global sea levels, due to warmer ocean currents that are hitting the ice sheets. The average monthly temperature there is -12 C to -35 C. “This melting of ice shelves has implications for sea level rise,” Gillett said. In 2002, a huge ice shelf on the Peninsula, called the Larsen B, broke apart and melted. It was 3,250 square kilometres in size, he pointed out. In addition, the team noticed data pointing to a warming along the coasts of East Antarctica, and they expect this warming to accelerate. Gillett hypothesised that the South Pole cooling may be due to a severe loss of ozone in the Pole’s atmosphere, due to pollution. He believes that because of his research, scientists can draw a more accurate picture of what the future may look like for Antarctica. Calculations about the melting of ice can now include the impact of global warming. “We won’t see anything catastrophic in the next century if things continue at the current rate. But the melt could accelerate,” Monaghan said. The IPCC was unable to include complete and accurate predictions of global sea rise because it did not have adequate Antarctic data. It predicted an increase of between 18 and 59 cm, Gillett said. In January, IPCC chairman Rajendra Pachauri made a personal plea to scientists to step up their research on Antarctica and Greenland. “My hope is the next [IPCC] report, if there is one, will be able to provide much better information on the possibility of these two large bodies of ice melting, in what seems like a frightening situation,” Pachauri said. Research about warming in the Antarctic Peninsula has been building. Earlier this year, Eric Rignot, of the University of California, reviewed satellite images from 1996 to 2000 and found that ice is definitely melting on the Antarctic Peninsula and in the West Antarctic. West Antarctica lost about 132 billion metric tons of ice in 2006, compared with about 83 billion metric tons in 1996, Rignot said. The Antarctic Peninsula lost 60 billion metric tons in 2006. The ice melt would have been enough to raise the world’s sea level by 0.5 mm, if not for a simultaneous ice accumulation in frigid East Antarctica, Rignot said. Research that shows humans are causing global warming may help bolster efforts to slow the emission of greenhouse gases, primarily by the United States and China, said Meg Boyle, a climate change expert with the environmental watchdog group Greenpeace. “In the United States, we have a small percentage of the world’s population but we produce 25 percent of the world’s global warming pollution. It is time for us to step up,” she said. She expressed hope that United States President-elect Barack Obama will be more willing to participate in global climate agreements.

Posted on Sustainabilitank.info on November 8th, 2008 Melting ice in the Arctic, but the lure of resources is just too strong. Europe’s Arctic adventure – The new cold rush for resources. EUOBSERVER / TROMSO – PART ONE – There’s this grizzled old guy in the hospital with worsening lung cancer. The doctors can’t tell him whether it’s fatal yet, but each new test shows a rapidly deteriorating condition. The man briefly thinks that he should just forget he ever opened the storeroom door and get back to the business of quitting, but he’s dazzled by the hoard and instead stuffs as much of it into his pyjamas as he can to take back to his bed and puffs his nicotine-addled brains out. There’s no tobacco hoard in a cupboard somewhere in the Arctic, but there is however a quarter of the world’s remaining undiscovered oil and gas now within reach as a result of the far north rapidly melting. Many of those living in the Arctic are aboriginal people, who have historically borne the double burden of underdevelopment in their regions and racial prejudice. And until recently very little has been available to anyone up north apart from far-from-bountiful farming and the occasional mine that inevitably closes down. Can we really say “No” to improving the standard of living in the north through development, especially if it can be done sustainably? *** Methane burps: The situation at the top of the world has taken a sharp turn for the worse just in the last few weeks. On 6 September, leading European and American ice specialists at the US National Ice Center reported that for the first time, a ring of navigable waters around the Arctic ice cap opened up the fabled Northwest Passage through the Canadian Arctic archipelago – the maritime Holy Grail of a faster trade route from Europe to Asia sought for centuries by explorers – and the Northern Sea Route, also known as the Northeast Passage, over Eurasia, at the same time. Then, in late September, Swedish and Russian scientists found the first evidence that millions of tonnes of methane – a gas that is 20 times more powerful a greenhouse gas than carbon dioxide – is bubbling up from beneath the Siberian Arctic seabed. The amount of methane stored beneath the Arctic is greater than the world’s remaining global stores of coal and it is now rising up from the bottom of the ocean through “methane chimney” discovered by scientists aboard the research ship Jacob Smirnitskyi. Days later, British scientists aboard the James Clark Ross found hundreds of plumes of methane burping up from the Arctic seabed to the west of the Norwegian archipelago of Svalbard midway between mainland Norway and the North Pole. NASA’s top climate scientist, James Hansen, says that the release of methane clathrates from permafrost regions and beneath the seabed will unleash powerful feedback forces that could produce runaway climate change that cannot be controlled – the so-called methane time bomb – a prediction of radical environmental transformation far worse than the worst-case scenarios theorised by the UN’s Intergovernmental Panel on Climate Change. Then on Tuesday (28 October), the European Space Agency reported that Arctic sea ice was thinning at a record rate, with the thickness of sea ice in large parts of the Arctic having declined by as much as 19 percent last winter compared to the previous five winters. *** Last days of the ‘ice bear:’ “The Arctic is warming at two times the rate of the rest of the world,” says Nalan Koc, a senior scientist with the polar climate programme at the Norwegian Polar Institute, in Tromso, explaining why all of this is happening. Tromso, in the far north of Norway and home to the world’s northernmost university, at the same time is preparing itself for the economic bonanza that the melting will bring. Nalan Koc, however, is not as excited as other Tromso inhabitants. In a Power Point presentation of this Arctic apocalypse, she starkly lists the myriad ways in which the environment is fundamentally altering. “Amplified by positive feedback, the Arctic is seeing increased precipitation, declining snow cover, rising river flows, thawing permafrost, melting glaciers, retreating summer sea ice, rising sea levels, and ocean salinity changes making the water less saline.” The talk, despite its subject, is deceptively banal. Where are the four horsemen? A moon turned blood-red? Instead, the end of days is being announced not by skeletonous biblical heralds but in bullet points and embedded videos that take three minutes to load. The permafrost is melting under tundra that previously was stable, she explains, buckling roads and highways as the ground beneath them gives way. In the marine environment, sea temperatures are rising and the ice cover is melting. Ice-dependent species such as the polar bear, which the Norwegians more accurately call “isbjorn” or “ice bear,” as well as the walrus and the ringed seal all face an uncertain future. Some scientists believe the polar bear will be extinct by mid-century. “When you’ve been around up here for as long as I have, you begin to see it with your own eyes from year to year,” she says. “You can feel it in your bones.” Last year saw a record low extent of Arctic sea ice cover – 4.3 million square kilometres – more than 40 percent below averages in the 1980s and more than 20 percent below the previous record low in 2005. “But more important than the extent is the volume of the ice. Most of the older thicker ice is not surviving from one summer to the next. As of 2007, most of the ice was three or four-year-old ice. As of 2008, most ice is just one year old.” The massive ice loss and thinning is forcing scientists to quickly ratchet lower even their worst expectations – the 2007 melting came some 30 years ahead of model predictions. In 2004, it was predicted that the ice would have melted sufficiently to allow commercial traffic in the Arctic Ocean by 2090. In 2007, it was predicted that commercial traffic would be able to cross by 2040. As of 2008, the predictions are for some time in the next five years, with the first start-up possibly in 2009. Models now predict an ice-free Arctic Ocean in the summer some time between 2013 and 2040. The last time the Arctic Ocean was ice-free in the summer was over a million years ago. Her colleague, Kit Kovacs, the Biodiversity Research Programme leader at the institute says: “The changes are happening so rapidly that scientists are having trouble processing it all. From initial tests to publishing papers takes at a minimum months or a couple of years, but change is happening much faster than that. “The biodiversity loss is just as profound as if there were a loss of the Amazon rainforest within the space of five years.” *** Oil and gas bonanza: What looks like the end for the polar bear, however, looks like Christmas for resource companies and European energy security concerns. Johan Petter Barlindhaug, the chair of North Energy, a northern-Norway-based oil-and-gas start-up currently exploring energy sources on the Norwegian continental shelf, says the melting Arctic could offer northern peoples, who have historically lived in a very much underdeveloped region, a chance to have similar standards of living as those who live in the cities and towns further south. “Climate change poses lots of threats, but it also opens up a range of possibilities,” he says. Oil companies like North Energy and Norwegian energy giant Statoil Hydro believe the Arctic holds as much as 25 percent of the worlds undiscovered oil and gas deposits – as much as the combined reserves of Canada and Saudi Arabia. Russia’s Gazprom already has approximately 34 trillion cubic metres (113 trillion cubic feet) of gas under development in the Barents Sea and Moscow is claiming territory in the Arctic that contains an estimated 586 billion barrels of oil. Mineral resources may also abound, particularly coal, iron, lead, copper, nickel, zinc and sulphides, as well as precious minerals such as gold and diamonds. Recent diamond discoveries in the Canadian Arctic have made the country, which previously didn’t produce any of the stones, the third biggest exporter of diamonds in the world. On maps that place the North Pole at the centre of the world, instead of the equator, Mr Barlindhaug shows how a melting Arctic also opens up three different shortcuts for shipping goods between Europe and Asia – routes that will save shipping firms, exporters and importers, and the world’s navies and smugglers – billions of euros. The shipping industry is hoping for a 20 percent saving, he enthuses, with still greater savings for the megaships that cannot fit through the Suez or Panama canals and have to sail round the tips of Africa or South America. Although Mr Barlindhaug believes that the third shortcut – straight across the pole – offers the most potential. “The Northwest and Northeast Passages aren’t as important as building ports on Iceland and in Norway and Russia,” he says. “This is because the Canadians view the Northwest Passage as domestic, and there’s something of the same with the Northeast Passage, which is within Russian borders. “In any case, international waters closer to the North Pole provide routes that are much shorter. But it’s also a matter of speed and cost. Between the Canadian or Russian islands, you can’t pick up much speed while you’re navigating through them. It’s too narrow. “But at 20-25 knots across the pole, then you’re really saving some money. It would take just five days to cross from the Bering Sea to the Barent Sea. It doesn’t need to be completely ice free.” He then moves on to the expanded fishing opportunities and potential for discoveries of new medicines derived from invertebrates living in extreme polar environments that round out the economic bounty becoming available as the climate warms up. Some 10 percent of global white fish stocks swim through the waters of the Barents Sea, the Bering Sea, and near Iceland, offering catches worth billions of euros. Nonetheless, “bio-prospecting” for new medicines is by far the greater catch, believes Mr Barlindhaug: “These invertebrates are chemical factories that will produce the next generation of medicines. They’re far more important than the fish that is up there.” In a visit to brand-spanking new labs at the University of Tromso, Jeanette Andersen, of Mabcent-SFI, a public-private bio-prospecting outfit launched last year with €20.5 million (180m NOK) in funding, explains the potential for new treatments and cures coming from molluscs that poison passing fish or colourless mini-starfish that love the cold. “The marine environment in the high Arctic is unparalleled with respect to combination of temperature and light regimes,” she says. “This implies evolution of organisms with unique physiological and biochemical adaptations.” She says that the potential is enormous, from antibiotics, chemotherapy, and painkillers to anti-bacterials, anti-oxidents, anti-inflammatory medicines, but Mabcent also hopes to discover creatures that have cosmetic and industrial applications, and even better food and drink preservation. “But all high-profit,” she enthuses, describing how her biologist and chemist colleagues dive off into the depths of the Arctic Ocean like a team of submariner Indiana Joneses, before they race back to the university to freeze the hundreds of different specimens. They then grind them into a pulp that is investigated by viking boffins at stupidly expensive machines who identify the wild new molecules produced by the exotic biochemistry of these nigh-on alien creatures. “Living in environments that range from 1.8 to 8 degrees celsius, these organisms are adapted to cold temperatures. As you warm up the metabolism, you speed up the effectiveness of enzymes, so the thinking is that enzymes existing at these temperatures will work faster in warm humans.” However, some of the different industries opening up as Arctic waters open up pose a threat to others. Pooh-poohing the idea that oil and gas exploration threatens the environment, North Energy’s Mr Barlindhaug reckons it’s a massive expansion of unsustainable fishing practices and illegal fishing that pose the greatest threat, particularly to bio-prospecting. “Bottom trawling is much more damaging than oil and gas exploration, as the you find oil all over the rocks and sand on the sea bed. These creatures are used to it – there’s nothing to worry about from oil and gas exploration. “Bioprospectors should be more scared about increased fishing activity. That’ll damage these organisms much more,” he insists. Jeanette back at Mabcent is not so sure: “We need to be worried about oil and gas exploration. What Mr Barlindhaug said is too easy an answer to the question of oil spills. Some organisms will adapt, yes, but others are very vulnerable.” In the second part of the EUobserver’s look at the politics and business of the melting Arctic, appearing on Monday, we look at Kirkenes, a small harbour town sometimes called ‘Little Murmansk’ for its 10 percent Russian population, and how it is set to be transformed by the oil and gas bonanza opening up as the ice disappears. ### |

Posted on Sustainabilitank.info on September 30th, 2008 Scotland to build world’s first ‘wind farms under the sea.’ By Jenny Haworth, Environment Correspondent, The New Scotsman, September 29, 2oo8. SCOTLAND has taken a major step towards leading the way in marine renewable energy with the announcement that the world’s first tidal farms could be built within three years. Two tidal projects, each with up to 20 turbines, could be installed on the seabed in the Pentland Firth and the Sound of Islay. A third is planned off the North Antrim coast in Northern Ireland. The aim is that all the underwater turbines would be constructed in Scotland, kickstarting the renewables industry in this country. ScottishPower Renewables will apply for planning permission for the three tidal projects next summer. If permission is granted, they would be the first commercial underwater tidal turbine farms built anywhere in the world. The structures stand 30 metres tall and can work as deep as 100 metres. The 20-metre blades would turn at least 10 metres below the surface to avoid shipping, developers said, and the zones would be off-limits to trawlers for safety reasons.
He said Scotland has the best tidal resources in Europe, with the Pentland Firth alone containing enough energy to meet a third of Scotland’s power requirements. “The rapid technological advance of tidal power has been startling and is now allowing us to progress plans for substantial projects delivering major environmental and economic benefits,” he said. “Tidal power is completely renewable, being driven by the gravity of the sun and moon, with no carbon dioxide emissions, plus the added benefit of being entirely predictable.” First Minister Alex Salmond, who will visit Caithness, near the potential site of the tidal farms, described the announcement as “significant”. He said: “We have an estimated 25 per cent of Europe’s tidal resource and 10 per cent of its wave potential. That is why this announcement is so significant.” Before it can be deployed, a £6 million prototype will have to be tested for about a year in Scottish waters, probably off Orkney. Engineers rising to the challenge of harnessing tidal power: Even though the devices seem likely to be the first to be used in a large-scale commercial tidal farm, many other machines are in development in what is set to become a very competitive market. Marine Current Turbines, based in Bristol, installed a 300kw tidal turbine called Seaflow off Lynmouth, Devon, in 2003. It’s a two-bladed rotor connected to an electrical generator mounted on a single steel tower drilled into the seabed. The Engineering Business, based in Newcastle, is developing the Stingray tidal generator, which uses the flow of the tide over a hydroplane, similar to an aeroplane wing, to generate electricity. In 2002 the 180-tonne, 150kw machine was tested in the Yell Sound, Shetland. SMD Hydrovision, based in Tyne and Wear, has developed the TidEL concept, which consists of a pair of contra-rotating 500kw turbines, mounted together on a single crossbeam. The unit is buoyant and tethered to the seabed, allowing it freedom of movement. The turbines can automatically align themselves downstream of the tidal flow as it changes during the day. *** IN NUMBERS: 40 – Turbines that could be built in Scottish waters by 2011. 40,000 – Homes that could be powered by the three turbine farms. 80 – The percentage of the UK’s potential tidal power in Scottish waters. ### |

By MICHAEL RICHARDSON, Thursday, Sept. 25, 2008, The Japan Times. Indeed, some of the world’s biggest economies and energy users, including the United States, Japan, China, India, South Korea and Canada, are racing to develop production techniques and equipment to tap gas hydrate and bring it to market within the next decade. For all of them, except energy self-sufficient Canada, the ability to tap new domestic sources of natural gas offers the prospect of substantially reducing dependence on expensive gas imports. Hydrate deposits up to several hundred meters thick are generally found in two places: on or beneath the deep ocean floor, or underground close to the Arctic permafrost layer, where high pressure and cold temperatures turn natural gas (methane, ethane and propane) into semi-solid form. Gas hydrate looks like ordinary ice, although it is sometimes discolored. But when brought to the surface and allowed to warm, it can be lit with a match. It then burns with a soft orange flame. One cubic meter of gas hydrate releases as much as 164 cubic meters of natural gas, in which methane is usually the chief constituent. The presence of hydrates has been inferred from seismic surveys and subsea sampling along most of the world’s continental shelf margins. Some of the biggest deposits so far found are on the ocean floor off Japan, South Korea, India and China, and on and off U.S. and Canadian Arctic land territory. Japan’s economy, trade and energy ministry announced last year that there were over 1.1 trillion cubic meters of methane hydrates in a Pacific Ocean trench, called the Nankai Trough, some 50 kilometers from the coast of Honshu, the main Japanese island. This reserve is equivalent to 14 years of gas use by Japan, which imports nearly all the oil, gas and coal needed to run its vast economy, the world’s second-largest after the United States. In doing so, Since last April, the U.S. has signed separate agreements with India, South Korea and Japan to cooperate in hydrate research, exploration and production. Japan, the U.S. and Canada, working in close collaboration, have achieved several days of continuous extraction of methane from underground hydrate reserves in the Arctic permafrost. Large-scale production tests are planned in the Canadian Arctic this winter and in the U.S. Arctic next year. Test production from offshore Arctic finds is expected to lag by three to five years, because marine deposits are less well documented than those on land. Sea sampling and drilling are also much more expensive. Japan said recently it plans to start test drilling in the Nankai Trough in 2012, possibly leading to commercial production by 2016. Korea has a similar production timetable. However, apart from the high costs and technical challenge, all the hydrate explorers face another possible danger — environmental disaster. While governments are attracted to an abundant clean fuel, scientists are concerned that drilling when combined with global warming risks disturbing the seabed and triggering an uncontrolled release of methane, a potent greenhouse gas. The British government’s former chief scientific adviser, Sir David King, warned recently that one big unknown about global warming is the stage at which dangerous tipping points may be reached that lead to runaway heating of the planet. He cited as an example the release of methane hydrate deposits in the Arctic. Some evidence suggests that a catastrophic release of methane from the ocean 55 million years ago, possibly caused by undersea volcanic explosions and landslides, was responsible for making the earth much warmer. The modern hydrate quest is built on a paradox. When released to the air, methane is a greenhouse gas that traps around 20 times more solar heat in the earth’s atmosphere than carbon dioxide, the main global warming gas. But when burned, methane releases up to 25 percent less carbon dioxide than combustion of the same amount of coal. It also emits no nitrogen and sulfur oxides, which poison the air and human health when coal is burned without effective filters. The world’s abundant methane hydrate deposits have been safely stored for thousands of years in the ocean depths and Arctic permafrost. Those who now seek to exploit what is probably the world’s greatest reserve of new fossil fuel must therefore be sure that in doing so they improve, not harm, the global environment.

Posted on Sustainabilitank.info on September 24th, 2008 The Methane Time Bomb.
*** The first evidence that millions of tons of a greenhouse gas 20 times more potent than carbon dioxide is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists. The Independent has been passed details of preliminary findings suggesting that massive deposits of sub-sea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats. Underground stores of methane are important because scientists believe their sudden release has in the past been responsible for rapid increases in global temperatures, dramatic changes to the climate, and even the mass extinction of species. Scientists aboard a research ship that has sailed the entire length of Russia’s northern coast have discovered intense concentrations of methane – sometimes at up to 100 times background levels – over several areas covering thousands of square miles of the Siberian continental shelf. In the past few days, the researchers have seen areas of sea foaming with gas bubbling up through “methane chimneys” rising from the sea floor. They believe that the sub-sea layer of permafrost, which has acted like a “lid” to prevent the gas from escaping, has melted away to allow methane to rise from underground deposits formed before the last ice age. They have warned that this is likely to be linked with the rapid warming that the region has experienced in recent years. *** Methane is about 20 times more powerful as a greenhouse gas than carbon dioxide and many scientists fear that its release could accelerate global warming in a giant positive feedback where more atmospheric methane causes higher temperatures, leading to further permafrost melting and the release of yet more methane. The amount of methane stored beneath the Arctic is calculated to be greater than the total amount of carbon locked up in global coal reserves so there is intense interest in the stability of these deposits as the region warms at a faster rate than other places on earth. Orjan Gustafsson of Stockholm University in Sweden, one of the leaders of the expedition, described the scale of the methane emissions in an email exchange sent from the Russian research ship Jacob Smirnitskyi. “We had a hectic finishing of the sampling programme yesterday and this past night,” said Dr Gustafsson. “An extensive area of intense methane release was found. At earlier sites we had found elevated levels of dissolved methane. Yesterday, for the first time, we documented a field where the release was so intense that the methane did not have time to dissolve into the seawater but was rising as methane bubbles to the sea surface. These ‘methane chimneys’ were documented on echo sounder and with seismic [instruments].” At some locations, methane concentrations reached 100 times background levels. These anomalies have been seen in the East Siberian Sea and the Laptev Sea, covering several tens of thousands of square kilometres, amounting to millions of tons of methane, said Dr Gustafsson. “This may be of the same magnitude as presently estimated from the global ocean,” he said. “Nobody knows how many more such areas exist on the extensive East Siberian continental shelves. “The conventional thought has been that the permafrost ‘lid’ on the sub-sea sediments on the Siberian shelf should cap and hold the massive reservoirs of shallow methane deposits in place. The growing evidence for release of methane in this inaccessible region may suggest that the permafrost lid is starting to get perforated and thus leak methane… The permafrost now has small holes. We have found elevated levels of methane above the water surface and even more in the water just below. It is obvious that the source is the seabed.” *** Dr Semiletov has suggested several possible reasons why methane is now being released from the Arctic, including the rising volume of relatively warmer water being discharged from Siberia’s rivers due to the melting of the permafrost on the land. ### |
