Young whale shark trapped in Taiwan Canal

Central News Agency Taiwan News 2 Mar 09;

Taipei, March 2 (CNA) A young whale shark became trapped in the Tainan Canal in the southern city of Tainan Monday, in what was the first such occurrence in the canal's 90-year history.

Members of the city's Fire Department and wildlife conservationists rushed to the scene to observe the whale shark, which is about 3 meters long and is believed to be a baby.

They have since been discussing how should the shark could be freed and returned to the open sea.

They believe that the whale shark swam into the canal from the nearby Anping fishing port, where expansion construction work is in progress.

Whale sharks, the world's largest fish, were added to Appendix II of the Convention on International Trade in Endangered Species (CITES) in 2002, which means whale shark products can only be sold with special permits.

At the beginning of 2008, Taiwan introduced regulations that banned the fishing, sale, importation and export of whale sharks.

The whale shark, known as the gentle giant of the ocean, is found in tropical and warm oceans. Believed to have originated about 60 million years ago, it can grow to lengths of up to 20 meters and can weigh up to 30 tons.

The species is called the "tofu shark" locally because its delicate meat purportedly looks and tastes like tofu. Whale sharks have been targets of harpoon fishing because their meat and fins fetch a high price on the international market.

Whale sharks are seen as having the potential to play an important role in eco- tourism because they are no threat to humans and it is considered safe to swim with them. There is a growing interest in the species among divers and dive businesses.

Before the government banned the fishing of the "tofu shark, " Anping was the country's largest whale shark fishing port, with catches sometimes topping 70 fish per year and some weighing up to 30 tons, according to Tainan fishermen.

Stranded whale shark freed from canal in Tainan
FIRST TIME: This is the first time in the canal’s 90-year history that a whale shark found itself trapped. Anping used to be the nation’s largest whale shark fishing port
Taipei Times 3 Mar 09;

A young whale shark that became trapped in the Tainan Canal yesterday was freed thanks to the efforts of the city’s fire department and conservationists.

Members of the city’s fire department and conservationists rushed to the scene yesterday morning after it was reported that a young whale shark measuring about 3m long had swum into the canal — the first such occurrence in the canal’s 90-year history.

Fire department staff first searched the canal on a lifeboat and a sampan, trying to help the whale shark swim back to the open sea.

But in the end, they managed to capture the whale shark using a fishing net before setting it free in the ocean.

They said they believed that the whale shark swam into the canal from the nearby Anping fishing port, where construction work was in progress.

Whale sharks, the world’s largest fish, were added to Appendix II of the Convention on International Trade in Endangered Species (CITES) in 2002, which means whale shark products can only be sold with special permits.

At the beginning of last year, regulations were introduced that banned the fishing, sale, importation and export of whale sharks.

The whale shark is found in tropical and warm oceans. It can grow to lengths of up to 20m and weigh up to 30 tonnes.

Protect our shores from erosion

Straits Times 2 Mar 09;

LAST December and the whole of January saw massive waves hitting our coastal areas. So forceful were these waves that debris and other flotsam could be seen lying on the high walkways, especially along Nicoll Drive from the direction of Telok Paku Road. Trails of destruction to the beach could also be seen all the way along the shores after SAF Ferry Terminal right up to Changi Ferry Terminal.

As a daily user of these parks, I have seen the devastation of this tranquil place. Concrete benches were overturned when the fine sand beneath gave way to the mighty waves. Also not spared were some once-majestic pine trees that went crashing onto the beach, while others with their roots exposed waited pitifully for the next round.

The National Parks Board (NParks) has acted swiftly by sending its contractors to the areas concerned. Overturned benches have been put back, albeit further inland, and the majestic fallen trees have been removed.

But something should be done as a long-term remedy. Melting ice caps are releasing millions of tonnes of water into the sea, causing rising sea levels. Why not place sandbags along affected coastlines and around the beautiful trees that dot the shores?

I also wish to bring to the attention of NParks another disturbing sight on the beaches. On weekends, hordes of beachgoers descend on these areas. They set up camps and party away with food and drinks. Many of these people openly smoke cigarettes. NParks has provided trash bins every few metres. However, they do not come with ashtrays. The smokers stub out their cigarettes on the sides of these bins, which leaves unsightly stains and may pose a fire hazard. If smoking is allowed in this area, NParks should provide ashtrays. Otherwise it should put up no-smoking signs.

Singapore plans lab to test cars' fuel efficiency

Scheduled for year-end, it will help sellers comply with new car label rule
Christopher Tan, Straits Times 2 mar 09;

MOTORISTS who buy new cars from next month will be able to know exactly how fuel-efficient their rides are.

Singapore will have, by the year's end, South-east Asia's first laboratory to measure fuel consumption and emission levels.

It is being set up on the back of the impending Fuel Economy Labelling Scheme, which will require all new cars to bear a label stating the number of litres a vehicle needs to run 100km. The centre is expected to be used by parallel importers, who will have problems meeting the requirements of the scheme since they do not get their cars directly from manufacturers.

Cars from official dealers come direct from the factory, so such dealers have access to the required fuel-efficiency data.

Until the Singapore lab comes up, parallel importers will need to have vehicles assessed at independent test centres. In the region, only Hong Kong has test facilities meeting Singapore's requirements.

The centre here will be sited at one of Vicom's vehicle-inspection centres and be run by Vicom, a subsidiary of transport giant ComfortDelGro.

Costing $5.8 million and half-funded by the Government, the centre will be able to test five vehicles a day - be they petrol, diesel, compressed natural gas, bi-fuel or hybrid electric vehicles, said a Land Transport Authority spokesman.

European test standards will be used.

The Straits Times understands that the lab will also be able to verify the data claimed by car firms.

The Ministry for the Environment and Water Resources (MEWR), which is spearheading the labelling scheme, believes that transparency about fuel consumption will help consumers make wiser choices when buying a vehicle.

A motorist who does so stands to save about $900 a year on fuel bills, said MEWR minister Yaacob Ibrahim last month.

Fuel efficiency is also good for the environment, since economical vehicles also tend to emit fewer tailpipe gases.

Mr Seah Seng Choon, executive director of the Consumers Association of Singapore (Case), said that with the fuel-efficiency figure spelled out, the demand for economical cars could well go up.

'This would in turn encourage car dealers to bring in more fuel-efficient models, which will benefit consumers in the long run.'

Meanwhile, parallel importers have appealed for unsold vehicles still in port to be exempted from the Fuel Economy Labelling Scheme for six months.

The economic slowdown has saddled them with an inventory of 'at least' 2,300 cars, said Mr Neo Nam Heng, who heads the Automotive Importers and Exporters Association.

This body of parallel importers is concerned that complying with the scheme will add to their costs.

Noting it will cost between $3,000 and $4,000 to test each car, Mr Neo said the association's members have agreed to pool resources to pay for the tests. It is not known how much of or whether their costs will be passed to the consumer.

LTA on fuel economy labelling scheme

# Will the label display fuel efficiency for all three driving modes - city, city-highway combined and highway driving?

No. The label will only display fuel efficiency for a combination of city and highway driving, since this is what the average motorist here experiences.

# Why are vehicles carrying more than eight passengers exempted? Don't they generally pollute the air more?

Only passenger cars and light goods vehicles need to be labelled. Passenger cars are those which carry up to seven passengers excluding the driver, and which have an unladen weight of up to 3 tonnes. This is in line with the definition of motor cars in the Road Traffic Act.

# What about imported used cars?

All second-hand cars are exempted.

Almost 200 whales stranded on Australian island

Reuters 1 Mar 08;

CANBERRA (Reuters) - Almost 200 pilot whales and a small number of dolphins have beached themselves on an island near Australia's southern state of Tasmania, wildlife officials said Monday, with many already dead.
Rescuers were on their way to Naracoopa beach on King Island, between Tasmania and the Australian mainland, where around 194 pilot whales and seven dolphins beached late on Sunday, said Chris Arthur, from Tasmania's Parks and Wildlife Service. Arthur said around 140 of the whales had already died, but authorities and civilian wildlife rescuers were confident the remaining mammals could be saved, with weather conditions calm.

"These are fairly robust animals, pilot whales," Arthur told Australian state radio. "While there are animals alive, there is always hope," he said.

The latest mass beaching takes the number of whales stranded in Tasmania's northwest over the past three months to more than 400, and follows the deaths of 48 sperm whales in January.

Pilot whales are among the smaller whales, typically up to about 5 meters (16 feet) in length and dark with a grey underbelly.

Mass strandings of whales occur periodically in Australia and New Zealand for reasons that are not entirely understood.

Theories include disturbance of echo-location, possibly by interference from sound produced by human activities at sea.

Human factor suspected in mass beaching of whales in Australia
Lewis Smith, Times Online 2 Mar 09;

Conservationists are demanding an immediate and thorough inquiry into what they say is the suspicious stranding of 200 whales and dolphins.

Fears that the mass stranding on an Australian beach on Sunday was caused by human disturbance were raised because two species of cetacean came ashore simultaneously.

Most of the animals were pilot whales, but a number of bottlenose dolphins were also among the pod.

Residents joined wildlife workers to spend hours keeping the surviving animals wet and cool before they could be lifted, pushed and hauled back into the water.

The rescue operation succeeded in saving 54 pilot whales and five dolphins on Naracoopa Beach on King Island, Tasmania. Most of the beached animals were dead by the time anyone could reach them.

Wildlife workers and volunteers were delighted to have saved more than a quarter of the whales and dolphins, but they were maintaining a watch on beaches in the area for fear that some of the creatures might come ashore again during the next high tides. Officials of the Tasmanian Parks and Wildlife Service were trying to discover last night why 192 whales and seven dolphins had beached themselves but said that the stranding, like many others before, was likely to remain a mystery.

Mark Simmonds, of the Whale and Dolphin Conservation Society and an expert on cetacean strandings, said that two species coming ashore together was enough to arouse suspicions of a human factor, including the use of sonar by the military.

“To get more than one species is unusual,” he said. “When you do, you get more suspicious because it means that they might have been driven. It does make us worried. We are certainly going to call for a very thorough investigation.”

Military sonar has been strongly linked to several strandings, particularly of deep-diving species such as pilot whales. Other human noises that could have frightened or disorientated the animals include industrial activities.

Another prime suspect among the possible causes is climate change, which scientists fear may be causing whales and dolphins to get close to unfamiliar coastlines.

Several species have migrations that take them close to the Tasmanian shore - 80 per cent of Australian strandings take place in Tasmania - and changes in water temperature caused by climate change could be driving them off their usual routes.

However, Dr Simmonds accepted that an explanation for the stranding could equally well be natural, such as the marine animals making a simple navigational error.

Factors leading to natural strandings are little understood but researchers believe that they are likely to be linked to group behaviour.

“Pilot whales are one of those species that do tend to feature in mass strandings, which is probably because they are a very social species,” Dr Simmonds said. “Out at sea there's nowhere to hide but behind each other, so when one gets into trouble the others follow.”

It is the fourth time in the past few months that a large stranding has taken place on Tasmania's coast. Chris Arthur, of the Parks and Wildlife Service, said: “This last summer has been a particularly demanding one.”

Ninety-seven animals of two species - long-finned whales and bottlenose dolphins - were stranded in November 2004 on King Island.

Asia's biofuel dreams shelved as crude oil tumbles

AFP Google News 2 Mar 09;

KUALA LUMPUR (AFP) — Hopes of a biofuel bonanza for Southeast Asia, raised when sky-high oil prices made the search for alternative fuels a priority, have been shelved as global fortunes and crude prices nose-dive.

Back when movie stars won plaudits for driving hybrid cars, and grains and oils were going cheap, regional governments grew excited over producing biofuel to lower energy costs and soak up agricultural stockpiles.

Malaysia and Indonesia, which produce most of the world's palm oil, heavily promoted their version of biofuel -- a mixture of diesel with five percent processed palm oil.

But the excitement evaporated as crude oil, which peaked at 147 dollars in July 2008, fell to current levels below 37 dollars.

That triggered a massive drop in palm oil prices from 1,245 dollars per tonne a year ago to 405 dollars per tonne last December.

Although palm oil prices have now recovered slightly to 526 dollars per tonne, supply has been disrupted as many firms shut down production or refuse to sign long-term supply contracts because of the volatile outlook.

The Malaysian government says it will now review 91 biofuel plant licenses issued during the sector's heyday, as the majority are not operating.

"You see, we have been hit by the double whammy of low palm oil prices and low crude oil prices," deputy plantations and commodities minister Kohilan Pillay told AFP.

"The situation now is very low palm oil prices that have caused uncertainty in supply, and at the same time low crude oil prices that have reduced biofuel demand, and that is bad news," he said.

Back in 2006, Malaysia was aiming to be the global leader in biodiesel production, and launched the Asian region's first commercial biodiesel plant.

It was propelled by strong demand for biodiesel from Europe and as far afield as Colombia, India, South Korea and Turkey, but these days it has fallen back on domestic demand, mostly from the government sector.

"With such low prices in palm and crude oil, local producers have effectively shut down most of their biofuel production as the only demand going forward at the moment is coming from the domestic market," said Khoo Hock Aun, managing director of regional biotech company Cosmo Biofuels.

The Malaysian government is trying to stimulate the industry by making it compulsory to use biofuel in diesel vehicles.

"We are now trying to use up our biofuels stocks while trying to stimulate biofuel usage through a law passed last year that has made its use compulsory for all government diesel vehicles since February this year," Pillay said.

Pillay said the policy would be implemented in phases throughout the civil service and become mandatory for all privately owned diesel vehicles starting next February.

In Indonesia, the government recently proposed a 70.6 million dollar plan to support biofuel development, but low prices have it worried.

"What matters now is the uncompetitive biofuel price, which has affected production," said Evita Legowo, the energy and mineral resources ministry's top official on oil and gas.

"We've tried to raise subsidies for biofuel development. It's difficult," she said of plans to maintain a stable supply to the domestic market.

Last September, the government issued laws mandating biofuel use by manufacturers, businesses and power plant operators, with the state oil company required by law to sell fuel with at least a one percent biofuel content.

"We aim for a five percent biofuel use in our energy mix in 2025," Legowo added, insisting that Indonesia has not stepped back on biofuel research and development.

The malaise in the industry has suspended for the moment a debate over the environmental impact of biofuel, which campaigners had said was a new cause of deforestation and destruction of wildlife habitats.

The boom triggered vast new plantings of palm oil in Indonesia and on Borneo island which is shared between Malaysia and Indonesia, which environmentalists said threatened orangutans, tigers and rhinoceros.

The production of biofuels from agricultural commodities was also blamed for pushing up food prices, in a report by the UN's Food and Agriculture Organisation last year.

Obama’s Backing Raises Hopes for Climate Pact

Elisabeth Rosenthal, The New York Times 28 Feb 09;

Until recently, the idea that the world’s most powerful nations might come together to tackle global warming seemed an environmentalist’s pipe dream.

The Kyoto Protocol, signed in 1997, was widely viewed as badly flawed. Many countries that signed the accord lagged far behind their targets in curbing carbon dioxide emissions. The United States refused even to ratify it. And the treaty gave a pass to major emitters in the developing world like China and India.

But within weeks of taking office, President Obama has radically shifted the global equation, placing the United States at the forefront of the international climate effort and raising hopes that an effective international accord might be possible. Mr. Obama’s chief climate negotiator, Todd Stern, said last week that the United States would be involved in the negotiation of a new treaty — to be signed in Copenhagen in December — “in a robust way.”

That treaty, officials and climate experts involved in the negotiations say, will significantly differ from the agreement of a decade ago, reaching beyond reducing greenhouse gas emissions and including financial mechanisms and making good on longstanding promises to provide money and technical assistance to help developing countries cope with climate change.

The perception that the United States is now serious has set off a flurry of diplomacy around the globe. “The lesson of Kyoto is that if the U.S. isn’t taking it seriously there is no reason for anyone else to,” said Bill McKibben, who runs the environmental organization www.350.org.

This week the United Nation’s top climate official, Yvo de Boer, will make the rounds in Washington to discuss climate issues. The United Nations secretary general, Ban Ki-moon, is organizing a high-level meeting on climate and energy. Teams from Britain and Denmark have visited the White House to discuss climate issues. In China, Secretary of State Hillary Rodham Clinton made climate a central focus of her visit and proposed a partnership between the United States and China. And a special envoy from China is coming soon.

But a global treaty still faces serious challenges in Washington and abroad, and the negotiations will be a test of how far the United States and other nations are prepared to go to address climate change at a moment when economies around the world are unspooling. The global recession itself is expected to result in a reduction of greenhouse gas emissions, as manufacturing and other polluting industries shrink, lessening the pressure on countries to take action.

“The No. 1 thing will be for everyone to see that the U.S. is on an urgent and transformational path to a low carbon economy — that would have a galvanizing effect,” said John Ashton, the British foreign secretary’s special representative for climate change.

The Obama administration has said that it will push through federal legislation this year to curb carbon dioxide emissions in the United States — a promise that Mr. Obama reiterated Tuesday in his speech to Congress.

The Kyoto Protocol has been a touchstone of the environmental movement. Thirty-seven developed countries, including Japan, Australia and nations in the European Union, ratified the accord, agreeing to reduce or limit the growth of carbon dioxide emissions by specified amounts. President George W. Bush, pressed by the Senate, rejected the accord, because countries like China were not also subject to mandatory emission levels. China and India also refused to ratify the protocol.

At the tail end of his administration, Mr. Bush made tentative overtures toward China and other countries on climate matters. In 2007, he convened a meeting of countries that were major emitters of greenhouse gases. Later, in bilateral economic talks, China and the United States agreed that they would cooperate on clean technology development and some other climate issues.

But Kyoto was shaped largely by climate scientists and environment ministers, not the higher-level officials now laying the groundwork. And even many who participated in the earlier accord now say they see it as weak and naïve about political and economic realities. Of the countries that signed, more than half are not on track to meet their targets according to 2008 United Nations data, including Germany, Ireland and Canada.

“In Kyoto we made a lot of promises to each other, but we hadn’t done the domestic politics,” Mr. Ashton said, “and that is why Kyoto — though a valuable step forward — has ultimately been so fragile.”

The talks on the new treaty, said Rajendra K. Pachauri, chairman of the United Nation’s Intergovernmental Panel on Climate Change, “provides an opportunity to fill this gap that we’ve seen, and this time perform up to expectations.”

The 1997 protocol was a narrow accord about the emissions of carbon dioxide and other heat-trapping gasses linked to global warming. The new agreement will need to address how those reductions can be achieved in a way that takes account of their effects on energy supplies and economies — especially at a time of global recession.

Negotiating the treaty when countries are under extreme economic stress presents challenges, Mr. de Boer acknowledged. Politicians in Italy and Canada have complained that it will be difficult to clean up industries to meet their Kyoto goals because of the economic downturn. But others say a global industrial recession, in which emissions tend to drop anyway and countries are poised to spend billions to stimulate economies, is the time to craft a global effort to combat global warming.

With developing countries like China and India emerging as major carbon dioxide emitters in the past few years, experts said that if the new treaty was to be effective, every nation would have to accept emissions limits. “If one part of the world acts and the other does not, that doesn’t really generate a climate benefit,” said Mr. de Boer, who is responsible for organizing the December meetings.

Developed countries would most likely get binding numerical targets, as some did in Kyoto. Developing countries, which were exempt under Kyoto, would probably be given less stringent goals, though it is not clear if these will be longer-term numerical targets or some other mechanism that ties allowable emissions to economic growth.

Mr. Obama has said the United States will lead the effort, but over the next months, he will have to show what exactly that means. A good first step, environmentalists say, would be to commit to trying to limit warming to two degrees centigrade above pre-industrial temperatures, an ambitious goal that the European Union has adopted but that the Bush administration steadfastly avoided. It could also pledge to reduce emissions by 50 or 80 percent by 2050.

The Intergovernmental Panel on Climate Change has said that humans could largely adapt to two degrees of warming, but that a greater temperature increase could cause far more serious consequences, from a dangerous rise in sea levels to mass extinctions.

Climate experts added that the United States did not need to have in place national legislation to limit greenhouse gasses, a process that could take months, to negotiate in Copenhagen. “It’s not just about analyzing a piece of legislation,” Mr. Ashton said. “It’s about the feeling you get if you’re a leader sitting in Beijing. It’s like love; you know it when you feel it.”

A more complex issue is whether negotiators will retain the system of trading carbon credits that is central to the Kyoto Protocol, a kind of global commodities market for carbon.

That system allows developed countries that produce more than their allotted share of emissions to balance their emissions budget by investing in projects that curtail emissions elsewhere. Such projects might include the cleaning up of a coal power plant in China, planting trees in Africa or converting pig manure to electricity in the Netherlands. The same cap and trade concept is now used in Europe’s emissions.

But as the European Union and the countries that signed the Kyoto Protocol have tried such projects over the past few years, problems have emerged. Most notably, it is hard to determine the emissions-reducing value of carbon credit projects, making it easy to game the system. The new treaty, experts say, will also have to broaden Kyoto’s focus beyond industrial emissions to activities like airline travel, one of the fastest-growing sources of carbon emissions. In the end, it will also have to include financial mechanisms and technical assistance to help developing countries cope with climate change.

“This is not just about emissions but about creating a massive investment in a new global energy economy” that includes forests, oceans and the transfer of technology, said Angela Anderson, director of the Pew Environment Group’s Global Warming Campaign.

American negotiators were limited in Kyoto by a Senate resolution saying that the United States would not accept numerical caps unless China did as well. But Senator John Kerry, Democrat of Massachusetts, said, “There has been a sea change in the Senate,” and he added that he believed that there were enough votes — Democratic and Republican — to ratify a strong treaty.

What is unclear is whether politicians will be willing to commit to large enough changes to have a significant effect on global warming. “The Bush administration set the bar very low,” Mr. McKibben said.

Contributing reporting were Mark Landler from Beijing and Andrew C. Revkin.

Global warming could delay, weaken monsoons: study

Yahoo News 1 Mar 09;

CHICAGO (AFP) – Global warming could delay the start of the summer monsoon by five to 15 days within the next century and significantly reduce rainfall in much of South Asia, a recent study has found.

Rising global temperatures will likely lead to an eastward shift in monsoon circulation which could result in more rainfall over the Indian Ocean, Myanmar and Bangladesh but less over Pakistan, India and Nepal, the study found.

It could also result in longer delays between rainy seasons and intensify the risk of deadly floods by leading to a significant increase in average rainfalls in some coastal areas of western India, Sri Lanka and Myanmar.

That could have a major impact on agriculture, human health and the economies of the region, warned study author Noah Diffenbaugh.

"Almost half of the world's population lives in areas affected by these monsoons, and even slight deviations from the normal monsoon pattern can have great impact," said Diffenbaugh, interim director of Purdue University's Climate Change Research Center.

"Agricultural production, water availability and hydroelectric power generation could be substantially affected by delayed monsoon onset and reduced surface runoff."

The atmospheric conditions that lead to reduced rain also can lead to intensification of extremely hot conditions, said lead author Moetasim Ashfaq, a graduate student at Purdue.

"In the past when we have seen extremely hot days, we have observed a similar circulation anomaly," Ashfaq said in a statement.

"These circulation changes decrease moisture flow over the land, and we see longer periods without rain, along with hot conditions."

Ashfaq used a high-resolution climate model to map how global warming will affect the complex topography of South Asia by recreating the monsoon season of past years.

He found that increasing temperatures strengthen some aspects of large-scale monsoon circulation but weaken the fine-scale interactions of the land with the moisture in the atmosphere.

"Even with a strong monsoon system, if circulation changes enough to change where and when rain is delivered, then that could have an impact that has not been captured in the large-scale evaluations," Ashfaq said.

The study was published in the January issue of the peer-reviewed journal Geophysical Research Letters.
