S$30m Keppel Bay Bridge opens to much fanfare

Channel NewsAsia 3 Jan 07;

SINGAPORE: A new S$30 million bridge to link Marina Bay and Keppel Island has been officially opened by President SR Nathan.

The Keppel Bay Bridge forms part of the new waterfront living experience in the Marina Bay area.

The 250-metre bridge links Keppel Island with the mainland. But it's more than just a bridge. The new link is adorned with special lights which can be programmed to enhance the atmosphere.

It took two years to complete the bridge, which is part of the master plan to transform Keppel Bay into a premier waterfront precinct.

Teo Soon Hoe, Senior Executive Director of Keppel Corporation, said: "We wanted to build a bridge between the mainland and the island. The island is now linked with a marina clubhouse. The boats are already in. It's just been completed and will be open soon. And we have the whole island which will provide more space to our tenants."

The bridge will come in handy when more water sports events are held here. And come January 19, the 10-team Clipper fleet presently racing from Australia to Singapore will be arriving at Marina Bay, and this bridge will be a central figure for the welcome party.

Apart from scenic views of Sentosa Island as well as the upcoming integrated resort, pedestrians can also get insights into the historical surroundings from the plaques placed along the walkway. - CNA/vm


Keppel Bay Bridge: a new waterfront icon
Business Times 4 Jan 08;

SINGAPORE'S newest bridge was officially opened by President SR Nathan yesterday evening to the accompaniment of a spectacular pyrotechnics show. It is the first public bridge to be built by a private developer and will be handed over to the Land Transport Authority.

Spanning 250 metres, Keppel Bay Bridge is the longest cable-stayed bridge locally.

About 300 guests attended the grand lighting-up ceremony. The bridge links Marina at Keppel Bay and future homes on the private Keppel Island to the mainland.

Designed by DCA Architects and TY Lin International, the bridge cost $30 million to build and forms part of the 32-hectare waterfront living precinct of Keppel Bay.

Programmable special effects lighting allow the pylon and stay cables to be spotlit, and the dynamic LED lights along the span of the bridge can be changed for different occasions.

To commemorate the historical significance of Keppel Harbour, informative plaques are placed along both sides of the bridge.

These plaques feature images and nuggets of information on places of historical significance such as Sentosa, Labrador Park, Mount Faber and the former Keppel Shipyard.

Costs to go up as oil prices breach US$100 per barrel mark briefly

Channel NewsAsia 3 Jan 08;

SINGAPORE: For the first time, world oil prices briefly crossed the psychologically important level of US$100 a barrel on Wednesday. Analysts attribute the surge to tight supplies and continued strong demand.

One analyst said consumers are being hit by a double whammy with the high oil prices and the recent spike in food prices.

Song Seng Wun, CEO and Regional Economist, CIMB-GK Research, said: "I suppose if it had been any other time, say six months ago, it probably would not have meant that much because crude oil prices had been going up steadily for the last five years. It only became a lot more significant now, coupled with the inflation in food prices.

"We have seen food prices go up significantly in the second half of last year and food prices, unfortunately, will stay high. CPI (consumer price index) may go up 2 percent or even beyond 5 percent year-on-year. Young Singaporeans may not have seen that kind of inflation in a long, long time."

"Even a small amount of inflation – such as what we are seeing today – can have a big impact on what you can do with your money. For example, S$100 today is reduced to just S$88 spending power by 2010 if we experience an inflation rate of 4 percent. And if that inflation rate is moved from 4 percent to 8 percent, that S$88 is reduced to just S$77 in 2010," said Gary Harvey, CEO of Ipac Wealth Management Asia.

The solution, however, is basic – see what you are spending on and budget carefully to stretch that dollar further.

While rising fuel and food prices will continue to have an upward impact on one's day-to-day costs, economists said there is a slight silver lining in that prices for consumer goods such as flat-screen TVs and mobile phones have remained unchanged or have even gone down.

This is because big manufacturers have managed to keep the prices down. But economists said that may not necessarily be the case in 12 months' time, if material or wage costs continue to climb.- CNA/so

That US$100 spike (and what it means to you)
Today Online 4 Jan 08;
Record oil prices fuel worries of hikes in food, transport prices here

A REBEL attack on an oil centre in Nigeria, Africa's biggest oil producer. Rough weather in the Gulf of Mexico, which slowed down the country's oil exports.

These two unrelated acts of man and nature thousands of kilometres apart came together on Wednesday to send shivers down the spine of Singaporeans — that prices of everyday items will rise again.

Oil traders found in the two events the perfect excuse to push prices further north — to the point of briefly touching the once unfathomable price of US$100 a barrel.

Although it was only for a brief moment, many analysts expect more roiling in the markets, with some energy specialists expecting not only US$100 oil, but US$120 oil in the coming year.

All eyes will now be on the Feb 1 meeting of the Organisation of Petroleum Exporting Countries (Opec), although oil officials are already playing down the prospect of any further rise in output to help ease prices. And with oil priced in US dollars, some analysts believe the big-producing nations may have an incentive to keep prices high to make up for the decline in value of the greenback.

In Singapore, consumers and businesses can expect even more price hikes in the next few months — in everything from imported raw materials, imported foodstuff such as vegetables, poultry and dairy products to transport fares, electricity bills and fuel surcharges.

Citigroup economist Chua Hak Bin told Today: "It wouldn't be a surprise that if oil prices keep on rising, some of the costs would go up. Earlier on, the MRT fare hike was rejected. But if the oil prices keep on rising, there is a chance that some of these increases could keep on happening."

Dr Chua also does not rule out inflation reaching 6 per cent in the first quarter.

"Minister Lim Hng Kiang indicated that inflation may hit 5 per cent in January. But with inflation already at 4.2 per cent in November — and taxi fares that shot up in December, electricity tariffs going up about 6 per cent and HDB assessment value going up 20 per cent — we think there is a real likelihood of inflation reaching 6 per cent."

But as inflation looks set to head north, stock prices seem to be southward-bound if the performances of key markets in the past 48 hours are any indication.

Wednesday's record oil prices, along with unexpectedly weak US manufacturing data, sent Wall Street into a spin — and Asian markets followed suit, with most shares down at yesterday's close.

The Straits Times Index dropped 64.16 points, or 1.9 per cent, to close at 3,397.06 — the biggest drop since Dec 17.

Gold, however, soared to an all-time high of more than US$866 an ounce as investors rushed to buy the safe-haven asset.

With oil prices expected to stay high — no thanks to continuing high demand from booming economies such as China and India — analysts remain divided over its impact on Asian economies.

Some analysts pointed out that oil prices have risen amid a global boom and the region's economies have so far been resilient.

Businesses, they noted, are far more fuel efficient than they were during the oil shock of the 1970s and Asian countries have tried to reduce their dependence on oil.

"The data we've seen through the third quarter is that the global economy has continued to grow strongly even as oil prices rose to these levels," Mr David Cohen, a regional economist with Action Economics in Singapore, told Associated Press.

"The question is, at what point does it become overwhelming?" he added.

Mr Adrian Loh, an energy analyst with Merrill Lynch in Singapore, said oil prices would need to be sustained above US$100 for more than six months before it affects consumer behaviour.

Ironically, an economic slowdown may be just what's needed to drive oil prices down from their stratospheric levels.

If there is a recession, "oil prices will definitely go down because demand will go down and the speculators who have come to see oil as an investment play will take a dip as a leading indicator — they will jump first and that will cause a meltdown", Mr Fadel Gheit, a senior energy analyst for Oppenheimer and Co, told the New York Times. — Agencies

Asian consumers fear US$100 oil will add to daily struggle
Channel NewsAsia 3 Jan 08;

SINGAPORE - From a Beijing cab driver to a vendor selling food wrapped in banana leaves at a Jakarta roadside, life for ordinary people in Asia is set to get even tougher after the price of oil hit 100 US dollars.

Consumers across the region griped about the rising cost of fuel after crude oil hit 100 dollars per barrel for the first time during trading in New York on Wednesday.

"What can I do? I just suffer," 30-year-old businesswoman Sirintra Vanno complained at a petrol station in Bangkok. "I have no choice but to drive every day to go to work because public transportation services are so limited."

Nena, an elderly woman who sells meals wrapped in banana leaves by the roadside in Jakarta, said higher fuel prices had dramatically cut her daily income over the past few months from 60,000 rupiah to 35,000 rupiah.

"I have to buy things at higher prices now but I cannot raise the price of food every time kerosene rises," she said.

Hery, 54, a motorcycle taxi driver in Jakarta, said he feared rising oil prices would lead to cuts in government subsidies for the cooking fuel, which costs 6,000 rupiah (64 cents) per litre.

"It will be out of reach" if the price goes higher, he said.

Australian truck driver Doug McMillan said the rising oil price was having a devastating impact on his business, which uses trailers to deliver farm equipment across the country's vast Outback.

McMillan said fuel costs used to account for about one-third of his expenditure but were now 55 percent -- and rising.

"By the time you pay your drivers' wages, there's no profit left," he told AFP by phone as he drove one of his rigs.

Song Haisheng, a 30-year-old taxi driver in Beijing, said he too was under pressure, adding he and many of his colleagues were barely surviving at current petrol prices.

"In order to save fuel, many taxi drivers now would rather park and queue along the street like this than cruise blindly as we used to do in search of customers," he said as he queued outside an office building in Beijing.

The Chinese government caps the prices at which refiners can sell their products, partly shielding consumers from the immediate impact of global oil spikes.

But it allowed refiners to raise domestic fuel prices by roughly 10 percent in November and ordinary Chinese now fear more hikes, with even the more well-off feeling the impact of record fuel prices.

"Nowadays I try not to travel by car when going on business trips and instead opt for the train as much as possible," said Huang, 42, who would only give his surname as he waited for his company driver to pick him up in Beijing.

On the streets of Manila, taxi driver Mario Agbayani was also worried.

"If pump prices continue to rise, I will be forced to look for another job because what I would be earning in a day would not be enough to even buy petrol," the 40-year-old father of three said.

He spends 12 hours a day on Manila's chaotic roads but takes home only 500 pesos (about 12 dollars) after expenses.

Japanese businessman Narihisa Murakami, 38, said in Tokyo that ordinary folks were powerless in the face of rising fuel prices, calling them "a real problem" and adding that fuel economy had become key when buying a car.

In Singapore, freelance motorcycle courier Irwan Shah, 45, said he tried to save by gassing up across the Causeway in neighbouring Malaysia, where petrol costs half the price it does in the city-state.

Another Singaporean courier, Surahman Ridwan, 52, resorted to a more drastic solution. "I had to cut down on cigarettes just to pay off my petrol costs more comfortably," he said. - AFP/ir

Oil prices may head to US$120 in next few months
Straits Times 4 Jan 08;

They could then fall back to about US$80 due to slowing external demand, say experts
By Yang Huiwen
ANALYSTS offered a stark warning yesterday after oil briefly touched the US$100 a barrel mark - it's going to get worse before it gets better.

They believe crude oil prices will keep rising over the next few months, driven by high demand and concerns over supply disruption and political tensions in oil-producing countries such as Nigeria, Iran and Algeria.

Speculative trading by hedge funds, thought to be behind the jump to US$100 on Wednesday, will also continue to play a part.

But economists believe prices will ease by the end of the year, while Singapore's rising dollar should also take some of the sting out of pricier crude.

CIMB-GK economist Song Seng Wun said: 'US$100 a barrel looks like an impressive number. That's higher than any time before, but it's probably not going to be a one-way street.'

He expects oil prices to average US$80 a barrel by the end of this year.

It is just the next few months that will test the nerves of economists, governments and consumers already shaken by the 57 per cent rise in prices last year.

'There will be a short-term propensity for prices to overshoot,' said OCBC Bank economist Selena Ling, who added that the high prices reflect the economic and political risks being faced across the globe.

'There is about a US$10 to US$15 risk premium on crude oil prices now,' she said.

She pointed out that, as the Organisation of Petroleum Exporting Countries (Opec) seems reluctant to ramp up production, prices could easily shoot up to US$110 a barrel over the next month.

Singapore-based economist David Cohen at Action Economics sees prices going even further north: 'US$120 a barrel could be well within reach from now till the middle of the year.

'Weakness in the US dollar has aggravated the pressure on oil prices, which are quoted in US dollars, in recent months.'

He added that continued softness in the greenback and general inflation fears will give oil prices a further upward nudge.

But it is not all a doomsday scenario. The possibility of an economic slowdown in the United States, the world's largest importer of oil, and easing growth in oil guzzlers China and India could suck off some of the steam.

Prices eased off in September and October due to heightened concerns about a US recession, said Mr Cohen.

Ms Ling, who forecasts oil will ease to about US$85 a barrel by year-end, added: 'It will be very hard to sustain this upward trend in the longer run, with the US, Europe and Japan slowing down. It will be very hard for just China and India to sustain the high prices.'

Standard Chartered economist Alvin Liew echoes her sentiments and predicts prices will go even lower, to an average of US$75 a barrel by the end of the year.

Mr Liew added there are other undetermined factors in play that could swing prices either way, including geopolitical tensions and the levels of speculative money in the market.

While higher oil prices and rising inflation generally batter consumer sentiment and constrict spending, the domestic picture is slightly rosier than it might seem.

'A strong Singapore dollar has somewhat compensated for higher oil prices,' said Mr Song. 'A lot will depend on how much further the Singapore dollar will strengthen to contain imported inflation.'

The strong economy has translated into more jobs and greater income growth for the past year, which have allowed people to live with the higher costs, he added.

Bali expands Monkey Forest for environment

Padang Tegal expands forest for environment
I Wayan Juniartha, The Jakarta Post 3 Jan 08;

The usually quiet Monkey Forest turned into a bustling field of activity on Sunday morning as the people of Padang Tegal celebrated the launching of the Tree Adoption Program, aimed at expanding the area into arguably the largest community-managed forest in the island.

The customary village of Padang Tegal comprises four banjar (traditional neighborhood organizations) with more than 2,600 residents and is the traditional custodian of the Monkey Forest, more than eleven hectares of woods to the south of Ubud.

Visitors consider the forest to be of Ubud's main attractions. The locals, who prefer to call the forest Wanara Wana, view it as a sacred sanctuary.

"The important Dalem Agung Padang Tegal temple and a holy springs of Beji lie inside the forest. The monkeys that dwell in the forest have always been considered by the locals to be the servants of the gods. That's the primary reason why the locals have always maintained and protected this sanctuary," the bendesa (head) of Padang Tegal customary village, I Made Dana, said.

Behind him, children from various kindergatens in Ubud were sitting in small groups under rows of young trees.

Each of them tried to capture the beauty of the surrounding nature on a piece of drawing paper. Sitting leisurely on the grassy field, still a bit wet due to the previous night's shower of rain, these children's innocence accentuated the woods' fresh natural beauty.

The drawing competition was part of Sunday's program, appropriately titled "Save the Planet and the Sacred Monkey Forest Sanctuary".

"Those young trees are the result of the reforestation program we carried out in 2003. Now, some of them are already six meters tall," the forest's promotion head Kadek Gunartha said.

Prior to 2003, the forest covered only seven hectares. But that year, the village assigned its young people to transform more than 3 hectares of village land south of the forest into wood.

"The reforestation and conservation activities have been carried out for years, but this year we realized the need for a better and wider promotional drive to inform the public at the regional and national levels of our efforts," Gunartha said.

This year, the village took the program to a new level by allocating more than Rp 2 billion out of its own budget to purchase one hectare of privately owned land bordering the forest.

"We will turn that land into forest, an extension of the original forest. In the future we will make several similar purchases to ensure the existence of this sacred forest," Made Dana said.

The move was simply extraordinary, particularly for the island, where villages generally spend billions of rupiah on religious rituals or renovating temples and not on environmental programs.

The expansion of the Monkey Forest, Gunartha explained, would serve several important purposes, the first of which was to provide a larger habitat for the forest's growing monkey population.

A census carried on June 2007 at 25 sites in the forest found out that there are now 346 monkeys living in three different packs.

"The number is expected to increase, so they will need a larger area both for playing and feeding. Soon, the number of the packs will increase to four because we have observed a significant power struggle in a pack that occupies the eastern part of the forest," I Dewa Gede Rai Putera, a physician responsible for the scientific aspects of the park's management.

The second aim is to increase the number and variety of the trees in the forest. So far, the forest houses 163 species of plants. The management now plans to add more local and rare species to the forest.

One way to achieve that is the Tree Adoption Program, which was officially launched on Sunday morning. By contributing Rp 150,000 (US$16), a visitor can have a specific tree planted in the forest.

"The management will maintain and take care of the tree, and will issue a certificate acknowledging the visitor's contribution to the program. The program is carried out in cooperation with the Gianyar chapter of the Indonesian Hotels and Restaurants Association (PHRI) and 58 visitors have agreed to join this scheme," Gunartha said.

The program, he said, was an excellent carbon emissions offset option for those who wanted wipe out the carbon debt they had generated during their trip to Bali.

The third objective was to turn the forest into a center of environmental studies for the locals.

"The forest will be a field laboratory to increase the awareness of the locals on environmental issues," Rai Putera said.

So far, the forest's management has carried out several scientific cooperation activities with researchers from Bali and abroad, including Udayana University (Bali), the University of Alabama, Central Washington University and the University of Notre Dame. The results have been published in more than eleven scientific publications.

"These cooperations help us in understanding the monkeys' behavior, thus, in minimalizing their aggressive attitudes and in providing them with the medical treatment they need. This research also confirms that the monkey populations are free from dangerous diseases, such as TB," he said.

Next year, the management will construct a compost plant inside the forest to teach locals how to make environmentally friendly fertilizer.

The fourth objective is to provide residents with rare plants that are essential to the rituals of Balinese Hinduism.

"We must be able to sustain our religious tradition without having to inflict a damaging burden on the environment," the bendesa said.

Around 200 meters to the north of the drawing competition site, hundreds of Padang Tegal youths were busy digging soil and planting trees in a large clearing. On a higher elevation, a Hindu high priest Ida Pedanda Gde Manuaba observed the activity with a smile on his face.

"This is the site of our Ritual Forest. Today, we are planting more than 20 species of ritual plants. We are still searching over the island for the other ritual plants," the forest's field manager I Wayan Selamet said.

When the activities ended on that bright Sunday morning, the people of Padang Tegal had added 700 more trees to their beloved sanctuary.

"The thing that really makes me proud is that everything has been done by our own people, including the management of this forest," I Made Dana said.

The bendesa has a good reason to be proud. Not many village in Bali have that kind of environmental enthusiasm.

Whatever Happened to Energy Conservation?

Michael Schirber, LiveScience.com Yahoo News 2 Jan 07;

The most talked-about solutions for global warming involve alternative energies, but the straightest line to reduced greenhouse gas emissions is using less energy, period.

"The cheapest, cleanest energy is the energy you don't use," said Jenny Powers of the Natural Resources Defense Council (NRDC).

The idea was once called energy conservation, but that gave the impression of sitting at home in the dark wearing three sweaters to stay warm. The more favorable term is "efficiency," which implies doing more with less.

A report issued earlier this year by McKinsey & Company, a global management consulting firm, found that adopting certain efficiency measures could cut the increase in the world's energy demand by more than half, without sacrificing economic growth.

"It doesn't seem as sexy as solar and wind, but efficiency is the cornerstone of reducing our environmental impact," Powers told Livescience.

Waste not

The world consumed 422 quads of energy in 2003 (a quad is a quadrillion BTUs, or the energy in 180 million barrels of oil). The United States alone used 92 quads in the same year, making it the largest single energy consumer.

The report, "Curbing Global Energy Demand Growth," predicts that global consumption will increase by 2.2 percent annually, reaching 613 quads in 2020. However, by becoming more efficient, the world could slow its growing appetite, so that only 478 quads are needed in 2020.

These cuts don't have to hurt. In fact, many of the report's energy-conserving proposals would pay for themselves in a few years, but the problem is that most people and organizations don't realize how they are being wasteful.

To raise awareness in the industrial sector, the Department of Energy has a program called Save Energy Now, which provides free energy assessments to the biggest energy-consuming plants in the nation. So far, assessors have visited more than 300 plants and identified more than $600 million in possible energy reductions, corresponding to 5.1 million tons of prevented CO2 emissions.

"This is why we are focusing on the largest consumers," said program manager Bob Gemmer. "The cost saving is a number you can get your arms around."

The assessments target fire-heating equipment and steam systems, which together account for almost 70 percent of industrial energy use. The DOE has recommended a range of efficiency improvements from adding proper insulation to installing a heat and power system that uses wasted heat to make electricity.

Companies are not obligated to make these changes, but Gemmer told LiveScience that many of the plants could cut their energy bill by almost 10 percent.

"There's a mindset out there that the best way to make money is to make more stuff," Gemmer said. But some companies could increase their profits by 50 percent just by reducing the cost of powering their plants.

Want not

Although industry accounts for 46 percent of energy consumption, more and more of the globe's energy is being used for homes, workplaces and transportation, especially in wealthier nations.

"Consumers are increasingly the driving force of energy consumption as the world economy has shifted away from industry and toward less energy-intensive service industries," according to the McKinsey report.

China alone could account for a third of the total growth in energy demand, thanks in large part to its burgeoning middle class and folks' desires for cars and appliances.

The report found the global residential sector had the greatest opportunity to reduce its energy demand by implementing better insulation, compact fluorescent lighting and high efficiency water-heating.

But surprisingly one of the biggest inefficiencies in the home is standby power: the little lights and displays that stay on when you turn something off. Standby power consumes between 20 to 60 watts, which may not seem like much, but over the course of a day it accounts for 4 to 10 percent of a house's energy consumption.

"The biggest standby culprits are your home computer and cable box," Powers said.

Why not

There is technology currently available that reduces standby power to 1 watt. In fact, most energy efficiency ideas—such as Energy Star appliances and sustainable architecture—exist right now, as opposed to some alternative energies, such as affordable solar panels that are still years away.

"Everything [in this report] is within the reach of today's technologies," said NRDC President Frances Beinecke. "Nothing needs to be invented. There are no magic wands. Americans will not be asked to live in trees or mud huts."

So what is holding us back? Part of the trouble is that efficiency does not have the big profile of a wind mill or a fuel-cell vehicle, Powers said. "You can't see it, touch it, taste it."

To increase perception, the report recommends that utility companies provide an itemized bill that lets consumers see how much each appliance is costing them and how much they could save by installing something more efficient.

Editor's Note: This article is part of an occasional LiveScience series about ideas to ease humanity's impact on the environment.

Global warming hits Australia with fires and floods in 2007

Rob Taylor, Reuters 3 Jan 08;

CANBERRA (Reuters) - Australia endured bushfires, floods and record high temperatures in its drought-ravaged foodbowl in 2007 as global warming brought the nation's sixth hottest year on record, the weather bureau said on Thursday.

The crucial Murray-Darling river basin, home to 2 million people and almost half the country's fruit and cereal crop, had its hottest known year, the Bureau of Meteorology said in its 2007 Australian Climate Statement.

The mean maximum temperature of 28.6 Celsius (83.5 Fahrenheit) was almost a full degree above normal, bringing record average temperatures to the heavily populated southeast, the bureau said, pointing to climate change as the reason.

"The standout year is 2005, which was Australia's warmest year on record, but essentially all the warm years that we've had have been in recent years," climate analysis spokesman David Jones told local radio.

Mean temperatures were above average across Australia every month last year except June and December. Recognizing the threat from climate change, Prime Minister Kevin Rudd ratified the Kyoto climate pact as his first official act after he was sworn into office early last month.

But despite widespread drought, a La Nina weather phenomenon bringing cooler temperatures to the Pacific helped lift rainfall to slightly more than average at 497mm.

"Such conditions are usually, but not always, associated with above-average rainfall across much of Australia. However, the 2007 La Nina event was slow to develop and its influence during winter and spring was confounded by a counter influence from the Indian Ocean," the bureau said.

La Nina, meaning "little girl" and the opposite of the El Nino weather phenomenon, brings rains to Australia's east and parts of Indonesia, as well as to the western United States.

The bureau said drought continued in the Murray-Darling basin, an area bigger than France and Germany, which normally provides 90 percent of Australia's irrigated crops and A$22 billion ($19.5 billion) worth of agricultural exports.

Deputy Prime Minister Julia Gillard said the latest bureau figures should silence climate change skeptics in Australia, one of the world's highest per-capita greenhouse gas polluters.

"What the bureau statement today confirms is the urgent need to act on climate change," she said.

Australia's Climate Institute said the bureau data showed global warming was not only about warmer weather, but also wilder and more unpredictable weather such as powerful storm cells and cyclones.

"Unfortunately, the reality is stacking up with all the projections," Chief Executive John Connor told Australian Associated Press. "The projections are for intense storms, flooding, droughts and bushfires and we had all of those."

Fears over fish stocks as jellyfish invade Baltic Sea

Tony Paterson, The Independent 3 Jan 08

Finnish marine biologists have identified a dangerous species of invasive jellyfish in the Baltic and raised fears that the creature has the potential to drastically reduce fish stocks in what is already regarded as one of the world's most polluted seas.

Evidence collected by scientists aboard the Aranda, a ship operated by the Finnish Institute of Marine Research, revealed that the Mnemiopsis leidyi species of jellyfish which caused huge declines in fish stocks in the Black and Caspian Seas had been sighted in the Baltic's Gulf of Finland.

Dr Markku Viitasalo, one of the institute's senior marine biologists, said yesterday that the crew of the Aranda spotted the species of combed jellyfish, which had never been seen in the Baltic before, while cruising in the eastern part of the Gulf of Finland last week. He said the species almost certainly arrived in the Baltic after leaving the waters off North and South America which are their natural habitat and entering the ballast tanks of container ships plying the Atlantic for Europe.

Dr Viitasalo told Der Spiegel magazine that the species had found its way into the Black and Caspian Seas by the same means and had almost completely wiped out fish stocks in both. The discovery followed other disturbing evidence collected by the Aranda which suggested that decades of effort invested by the countries of northern Europe in cleaning up the Baltic had made minimal impact so far.

The institute said research carried out by the ship's biologists had shown that the sea's already damaging phosphorus levels had actually risen off the coasts of Poland and Russia. "It is very important to monitor whether these efforts have had any effect and the answer is not yet," said Dr Viitasalo. Phosphorus, a by-product of agricultural fertilisers which are allowed to run off into the Baltic, and human waste promote the growth of blue algae. The weed-like substance pollutes the Baltic in summer, covering the sea's surface in acres of bad-smelling, green sludge which cuts the vital oxygen supplies needed by fish and other plant life.

Recent figures released by the Helsinki Commission or Helcom – a 10-member organisation comprised of Baltic seaboard countries which has been trying to cut the sea's pollution levels since 1974 – revealed that 730,000 tons of nitrogen and 36,300 tons of phosphorus were currently being found in the Baltic each year.

The organisation said that the amounts were enough to trigger massive algae pollution.

The Aranda's findings highlight the urgency of the latest attempt to rescue the almost completely landlocked sea. Last month the European Commission signed up to the Baltic Sea Action Plan, which aims to restore the sea to "good ecological status" by 2021.

The plan, which will be implemented from 2010, gives each of the Baltic's nine seaboard countries individual pollution reduction targets to cut phosphorus emissions by 15,250 tons and nitrogen by 135,00 tons annually. It also aims to step up efforts to protect declining fish stocks, reduce pollution caused by heavy shipping traffic and equip small communities which currently discharge their effluent directly into the Baltic, with proper sewers and waste treatment plants.

Unfortunately, the plan will do nothing to stop the Aranda's latest discovery and halt the jellyfish's spread across the Baltic.

Singapore moves towards a Zero Waste system

Letsrecycle.com 2 Jan 08;

In November 2008 Singapore will host the International Solid Waste Association annual congress. This article, by Jeff Cooper, president of the Chartered Institution of Wastes Management, looks at how far Singapore has progressed with its management of wastes.

In Singapore today, high proportions of waste are recycled and recovered and only minimal amounts landfilled. Even the waste currently going to landfill could in a short time be recycled.

Vaneeta Bhojwani, senior engineer in Singapore's resource conservation department of the National Environment Agency (NEA), explained that when Singapore Green Plan 2012 was adopted as its waste management strategy, it wanted to follow the principles of the waste hierarchy. However, the main target was to reach a 60% recycling rate for the island's waste by 2012.

Singapore has focused on waste minimisation, but had very limited powers to change the amounts of waste generated, especially from the household sector.

The first priority was to reach a voluntary agreement with retailers to reduce the amount of packaging given to households. Despite the limited amount of waste associated with the plastic carrier bag it is an iconic packaging product.

Following a successful initiative in April 2007 to stop handing out plastic bags Singapore's retailers have agreed that on the first Wednesday of every month they would institute a Bring Your Own Bag (BYOB) day. Members of the public can still have plastic bags, but they have to pay S$0.10 (£0.03) for each one. Recently, however, although there have been more retailers interested in joining the initiative among the public interest has waned. Therefore when reminding people that the next day is a BYOB day the reaction of many members of the public has been to stock up with extra bags on the previous Tuesday.

The national recycling programme pre-dates the Green Plan and again it is voluntary for households and businesses. Most of the island's population has the opportunity to participate in a fortnightly door-to-door collection of recyclable wastes and 86% of the households do.

In addition, there are 3,400 bring bins located throughout the island. These wastes are processed in two materials recycling facilities, but the reprocessing of the wastes mainly takes place elsewhere.
Collection

In 2001 Singapore decided to change the previous system whereby the State, through the NEA, undertook the collection of household waste (and its disposal) by contracting out the operation. Bids were sought for nine areas within Singapore for daily household waste collections and a fortnightly collection of dry recyclable wastes.

The initial contracts were phased and were for a period of five years, and during 2006 the collection contracts were re-tendered for the first time for seven years, which will be the normal length of contract for the future. Four of the contracts are held by a local company, formed from the rump of the old state waste collection enterprise, three are held by SULO, now taken over by Veolia, and the other two are held by local companies.

Despite pressure to go over to less frequent servicing of households' residual waste in order to enhance the recycling collections and segregate further waste fractions to date, that has been resisted.

The problem with fortnightly collections of recyclable wastes from Singapore's predominant high rise housing units is the time and effort needed to collect the wastes. Therefore in several cases this operation is sub-contracted out. Either the sub-contractor is paid for the tonnage of recyclable wastes collected and supplies the bags or the subcontractor is paid a fee for servicing the households and the bags are supplied to the sub-contractor.

A further issue is the loss of recyclable wastes from the households, or more usually from the bank sites that are raided by local entrepreneurs because the value of the main secondary materials are high at the present time. However, at least it is being reclaimed and recycled.

For industrial and commercial wastes there are a variety of recycling initiatives that have been developed by local companies, including the composting of horticultural wastes. Wood wastes are shredded to make particle board, achieving a 37% recycling rate, and plastics are recycled but at only a 12% rate. Nevertheless the majority of the commercial and industrial plastics are processed on the island and are often made into new products as well.

For construction and demolition (C&D) waste the recycling rate exceeds 90% and even the "slag" - shot-blasting materials used in the shipping maintenance and repair sector - is being re-utilised.

Recovery

In 2006 the overall Singapore recycling rate was 51%. Singapore expects to increase this further through the recovery of the 1,500 tonnes per day of IBA (incinerator bottom ash). A pilot plant for IBA processing has been built, partly aided by a research grant from the government, to evaluate the best options.

While state intervention is limited, it is helping to push more waste up the hierarchy. Therefore any waste that is combustible has to go into one of the island's incineration plants, all of which are owned and managed by the state and the cost is S$77 (£26) per tonne. Of the 7,000 tpd presented for incineration 57% comes from households and only 43% from commerce and industry.

The island's four incineration plants were built between 1979 and 2000 with the capacity of each one getting bigger each time. The first had a capacity of 800 tonnes per day, then another with higher capacity of 1,100 tonnes, the third 2,400 tpd finally 3,000 tpd for the last in order to accommodate ever increasing amounts of waste. Now due to Singapore's success in recycling more wastes, the first plant is to be replaced at the same capacity, 800 tpd, through a design build and operate contract and due to become operational in 2009 or 2010.

Outputs from the incineration plant included 938m kWh of electricity in 2006, around 3% of the island's consumption and 14,000 tonnes of scrap metal each year. Through the success of its waste reduction and recycling measures Singapore will be able to extend the time for replacement of its other incineration plants. However, those plants are likely to be contracted out as the NEA devolves direct responsibility for waste disposal operations.
Landfill

On 31 March 1999 the last mainland landfill was shut down to be replaced by an offshore landfill. This necessitated the building of a barge transfer station at so that all the incineration plants' bottom ash can be shipped together with the modest amounts of industrial and C&D wastes.

The 4% of non-combustible waste, plus the IBA, is currently consigned to the island's only landfill, Semakau, which was constructed in the 1990s as a land reclamation project with a 7km bund enclosing 2 small islands producing a 350ha site with 63m m3 capacity. Fully lined and carefully engineered it was expected to last Singapore 20-25 years. With the reduction of waste being sent for landfill it is now expected to last 35-40 years and potentially substantially longer if the IBA is recovered.

The island landfill was split into two areas with the first sub-divided into 11 tipping areas, of which six have now been filled. The water in each area remains fresh until it is needed for filling at which point the concrete culverts are blocked off and the water pumped out prior to filling. The second area has yet to be subdivided but when that has been filled to sea level the first area will be raised to a maximum of 25m above sea level and then the second landscaped with four hillocks. This will create an open space for informal recreation, or at least that is the current plan.

Even now the landfill is now being opened up for a variety of leisure and recreational purposes, including sport fishing, bird watching, walking the inter-tidal zone and star gazing.

The International Solid Waste Association's 2008 Annual Congress takes place in Singapore from 3-6 November 2008. There will be site visits to the landfill site and other waste management and recycling facilities as part of the programme. Abstracts are invited for the event by 15 March 2008.

What’s Your Consumption Factor? by Jared Diamond

Jared Diamond, New York Times 2 Jan 08;

TO mathematicians, 32 is an interesting number: it’s 2 raised to the fifth power, 2 times 2 times 2 times 2 times 2.

To economists, 32 is even more special, because it measures the difference in lifestyles between the first world and the developing world. The average rates at which people consume resources like oil and metals, and produce wastes like plastics and greenhouse gases, are about 32 times higher in North America, Western Europe, Japan and Australia than they are in the developing world. That factor of 32 has big consequences.

To understand them, consider our concern with world population. Today, there are more than 6.5 billion people, and that number may grow to around 9 billion within this half-century. Several decades ago, many people considered rising population to be the main challenge facing humanity. Now we realize that it matters only insofar as people consume and produce.

If most of the world’s 6.5 billion people were in cold storage and not metabolizing or consuming, they would create no resource problem. What really matters is total world consumption, the sum of all local consumptions, which is the product of local population times the local per capita consumption rate.

The estimated one billion people who live in developed countries have a relative per capita consumption rate of 32. Most of the world’s other 5.5 billion people constitute the developing world, with relative per capita consumption rates below 32, mostly down toward 1.

The population especially of the developing world is growing, and some people remain fixated on this. They note that populations of countries like Kenya are growing rapidly, and they say that’s a big problem. Yes, it is a problem for Kenya’s more than 30 million people, but it’s not a burden on the whole world, because Kenyans consume so little. (Their relative per capita rate is 1.) A real problem for the world is that each of us 300 million Americans consumes as much as 32 Kenyans. With 10 times the population, the United States consumes 320 times more resources than Kenya does.

People in the third world are aware of this difference in per capita consumption, although most of them couldn’t specify that it’s by a factor of 32. When they believe their chances of catching up to be hopeless, they sometimes get frustrated and angry, and some become terrorists, or tolerate or support terrorists. Since Sept. 11, 2001, it has become clear that the oceans that once protected the United States no longer do so. There will be more terrorist attacks against us and Europe, and perhaps against Japan and Australia, as long as that factorial difference of 32 in consumption rates persists.

People who consume little want to enjoy the high-consumption lifestyle. Governments of developing countries make an increase in living standards a primary goal of national policy. And tens of millions of people in the developing world seek the first-world lifestyle on their own, by emigrating, especially to the United States and Western Europe, Japan and Australia. Each such transfer of a person to a high-consumption country raises world consumption rates, even though most immigrants don’t succeed immediately in multiplying their consumption by 32.

Among the developing countries that are seeking to increase per capita consumption rates at home, China stands out. It has the world’s fastest growing economy, and there are 1.3 billion Chinese, four times the United States population. The world is already running out of resources, and it will do so even sooner if China achieves American-level consumption rates. Already, China is competing with us for oil and metals on world markets.

Per capita consumption rates in China are still about 11 times below ours, but let’s suppose they rise to our level. Let’s also make things easy by imagining that nothing else happens to increase world consumption — that is, no other country increases its consumption, all national populations (including China’s) remain unchanged and immigration ceases. China’s catching up alone would roughly double world consumption rates. Oil consumption would increase by 106 percent, for instance, and world metal consumption by 94 percent.

If India as well as China were to catch up, world consumption rates would triple. If the whole developing world were suddenly to catch up, world rates would increase elevenfold. It would be as if the world population ballooned to 72 billion people (retaining present consumption rates).

Some optimists claim that we could support a world with nine billion people. But I haven’t met anyone crazy enough to claim that we could support 72 billion. Yet we often promise developing countries that if they will only adopt good policies — for example, institute honest government and a free-market economy — they, too, will be able to enjoy a first-world lifestyle. This promise is impossible, a cruel hoax: we are having difficulty supporting a first-world lifestyle even now for only one billion people.

We Americans may think of China’s growing consumption as a problem. But the Chinese are only reaching for the consumption rate we already have. To tell them not to try would be futile.

The only approach that China and other developing countries will accept is to aim to make consumption rates and living standards more equal around the world. But the world doesn’t have enough resources to allow for raising China’s consumption rates, let alone those of the rest of the world, to our levels. Does this mean we’re headed for disaster?

No, we could have a stable outcome in which all countries converge on consumption rates considerably below the current highest levels. Americans might object: there is no way we would sacrifice our living standards for the benefit of people in the rest of the world. Nevertheless, whether we get there willingly or not, we shall soon have lower consumption rates, because our present rates are unsustainable.

Real sacrifice wouldn’t be required, however, because living standards are not tightly coupled to consumption rates. Much American consumption is wasteful and contributes little or nothing to quality of life. For example, per capita oil consumption in Western Europe is about half of ours, yet Western Europe’s standard of living is higher by any reasonable criterion, including life expectancy, health, infant mortality, access to medical care, financial security after retirement, vacation time, quality of public schools and support for the arts. Ask yourself whether Americans’ wasteful use of gasoline contributes positively to any of those measures.

Other aspects of our consumption are wasteful, too. Most of the world’s fisheries are still operated non-sustainably, and many have already collapsed or fallen to low yields — even though we know how to manage them in such a way as to preserve the environment and the fish supply. If we were to operate all fisheries sustainably, we could extract fish from the oceans at maximum historical rates and carry on indefinitely.

The same is true of forests: we already know how to log them sustainably, and if we did so worldwide, we could extract enough timber to meet the world’s wood and paper needs. Yet most forests are managed non-sustainably, with decreasing yields.

Just as it is certain that within most of our lifetimes we’ll be consuming less than we do now, it is also certain that per capita consumption rates in many developing countries will one day be more nearly equal to ours. These are desirable trends, not horrible prospects. In fact, we already know how to encourage the trends; the main thing lacking has been political will.

Fortunately, in the last year there have been encouraging signs. Australia held a recent election in which a large majority of voters reversed the head-in-the-sand political course their government had followed for a decade; the new government immediately supported the Kyoto Protocol on cutting greenhouse gas emissions.

Also in the last year, concern about climate change has increased greatly in the United States. Even in China, vigorous arguments about environmental policy are taking place, and public protests recently halted construction of a huge chemical plant near the center of Xiamen. Hence I am cautiously optimistic. The world has serious consumption problems, but we can solve them if we choose to do so.

Mandai development plan: Choose site with care

Letter from Wong Yew Kwan,
Former Commissioner of Parks and Recreation
Straits Times Forum 2 Jan 08

THE Straits Times recently carried articles concerning the Singapore Tourism Board's (STB) potential plan to create an eco-tourism area near the Singapore Zoo.

Needless to say, the STB's intention is good, for increased tourism will mean more money for Singapore. However, the question as raised by the Nature Society is that such a project, involving removal of vegetation and construction of buildings, would affect the plant and animal ecology, not only of the subject site but also that of the Nature Reserve, although the subject site, covering some 30 ha in size, is not part of the Nature Reserve.

Based on the map appearing in The Straits Times in connection with Ms Lim Wei Chean's article on Dec 7, and from the relevant biodiversity information I could gather, I agree with the Nature Society that, for the STB's proposed development, it would be far better to make use of the adjacent alternative site (hugging close to the Bukit Timah Expressway) proposed by the society.

I am not worried about plants in the present case, but the various animal species still found in the reserve, especially rare and endangered ones. If the forest of the STB site is undisturbed, the area would act as a good link or fording area for these precious animals to go between the forest on one side of Mandai Lake Road and the other. If the two STB proposed sites are used, then the fording link would be lost, and this would lead to isolation of the animal populations.

The alternative site proposed by the Nature Society is quite close to the zoo and it would not be difficult for tourists to go from there to the zoo and the Night Safari, should this be a desirable consideration. Indeed, with some planning, one could build an aerial link between the alternative site and the zoo or Night Safari. With such a link, visitors would cause minimal disturbance to the animal populations, day or night, while going between the two areas.

The article, 'Mandai at risk?' (The Sunday Times, Nov 25) cautioned that Singapore is not a choice site for such tourism activities. If we wish to promote eco-tourism, it is better for tourists to have excursions from their hotels which are not far away rather than from new chalets set up at the edge of the reserves - so there will be minimal disturbance to the natural environment.

Canada's climate change boomtown

Adam Fowler, BBC Radio 4 2 Jan 08;

"The next economic boom is going to happen in northern Canada and Churchill's going to be a part of that."

So says Mike Spence, a part Cree Indian and part Orcadian Scot who is mayor of the tiny Canadian settlement of Churchill on Hudson Bay.

When I first arrived in the sub-Arctic town in early October, I found his claim hard to believe.

No one was on the streets as I wandered alongside a freight train which had just arrived from Winnipeg, 1000km (600 miles) to the south.

Behind me was the port and the towering granary building - concrete and almost windowless.

Ahead the countless railroad trucks of grade A Canadian grain stretching far beyond the scattering of Churchill's low lying buildings.

Countless, because I had been warned not to stray beyond the town's limits as this was the beginning of polar bear season.

The weather forecast had suggested a 40% chance of snow, but instead there was low cloud and rain, with no sign of any ice yet on the slate grey water of Hudson Bay.

Global warming

Winters are coming later to Churchill these days, and it's global warming which Mike Spence reckons will bring the town's big opportunity.

"We need to define the benefits of climate change - and there are many. Look at a map of Northern Canada - there's only one deep water port and Churchill is it," says Mr Spence.

With the latest estimates of ice-free summers in the Arctic as early as 2013 and the Northwest Passage becoming navigable for the first time this year, Mr Spence claims that Churchill could find itself at the centre of a new network of international shipping routes.

Churchill can look to northern Europe as well as Asia, which puts it slap in the middle of an Arctic sea route that bypasses the Panama Canal and could shave two weeks off the journey between east and west.

$10 bargain

And if Churchill is to be the first boom town of the globally warmed age, one US company stands to do very nicely.

Ten years ago the dilapidated port and railroad were bought for just 10 Canadian dollars (£5; $10) by Omnitrax, a transportation services company based in Colorado.

Not a bad price for derelict infrastructure which nobody wanted because it was ice-bound eight months of the year.

That C$10 now looks like a very good investment indeed and while managing director of Omnitrax, Mike Ogborn admits that global warming was not a topic around the board table in Denver at the time, it certainly is now.

"We already see a lengthening of the season by at least two weeks and we anticipate that that trend will continue," he says.

"My big vision is that the port will be as busy as a beehive at least six months of the year, serving North America, Europe, the Middle East and Asia."

That optimism is shared by the man who negotiated the sale to Omnitrax, Canadian statesman Lloyd Axworthy, minister of transport at the time.

"If you look at the transportation potential there are all kinds of opportunities which, 10 years out, I think could quite dramatically change the entire sea transit system, globally."

He envisages Churchill as the key link in a chain, which would see goods arriving by ship from Europe and Asia, and then distributed by rail throughout North and Central America.

Arctic bridge

But the big vision for Churchill is not quite so clear out in the harbour where a tanker approaches through the mist to pick up that trainload of grain. It is sailing in with empty holds and, as pilot Brian Moulton explains, that is the norm.

"The inbound cargoes are few and far between. Usually, coming in, it's in ballast," he says.

"This year they have just one Russian fertiliser ship coming in."

That single Russian shipment, late in the season, was a historic arrival.

It was the first to use a proposed new route across the Arctic between Murmansk and Churchill.

Politicians have branded it "The Arctic Bridge".

"What we have demonstrated is that this route is possible and is worth trying. Now it is up to Churchill to market itself," says Pavel Sarbashev from the Murmansk Shipping Company.

On my last day in Churchill, Canadian Prime Minister Stephen Harper flew into this small community to announce a C$68m investment in the port and railway.

"As the world beats a path to our Arctic doorstep, our government is working hard to ensure that Canada is ready to greet them when they arrive," the prime minister told the town's residents.

Less than one thousand people live in Churchill. For the moment.

It is impossible to imagine how this neat and well kempt little town, rather beautifully landscaped from the rock and the scrubland on the banks of the Hudson Bay, will change if it does become a boom town in a warmer world.

And not that I want to pour cold water on its bright future, but as I leave for home I consider the natural as well as the economic uncertainties ahead.

For if sea levels rise too much, or the permafrost softens underneath the railroad, or Hudson Bay clogs up with ice floes from a disintegrating ice cap, or the Gulf Stream shifts direction, then Churchill's big chance could melt away.

Arctic cooked by Man and Nature

Nature and man jointly cook Arctic
Seth Borenstein, AP Yahoo News 3 Jan 08;
By SETH BORENSTEIN, AP Science Writer1 hour, 2 minutes ago

There's more to the recent dramatic and alarming thawing of the Arctic region than can be explained by man-made global warming alone, a new study found. Nature is pushing the Arctic to the edge, too.

There's a natural cause that may account for much of the Arctic warming, which has melted sea ice, ice sheets and glaciers, according to a study published Thursday in the journal Nature.

New research points a finger at a natural and cyclical increase in the amount of energy in the atmosphere that moves from south to north around the Arctic Circle.

But that energy transfer, which comes with storms that head north because of ocean currents, is not acting alone either, scientists say. Another upcoming study concludes that the combination of both that natural energy transfer increase and man-made global warming serve as a one-two punch that is pushing the Arctic over the edge.

Scientists are trying to figure out why the Arctic is warming and melting faster than computer models predict.

The summer of 2007, like the summer of 2005, smashed all records for loss of summer sea ice in the Arctic Ocean and ice sheet in Greenland. In September, the Arctic Ocean had 23 percent less sea ice than the previous record low. Greenland's ice sheet melted 19 billion tons more than its previous record.

The Nature study suggests there's more behind it than global warming because the air a couple miles above the ground is warming more than calculated by the climate models.

Climate change theory concentrates on warming of surface temperatures and explains an Arctic that is warming faster than the rest of the world as mostly because reduced sea ice and ice sheets means less reflecting solar rays.

Rune Graversen, the Nature study co-author and a meteorology researcher at Stockholm University in Sweden, said a shift in energy transfer explains the thawing more, including what's happening in the atmosphere, but does not contradict consensus global warming science.

Oceanographer James Overland, who reviewed Graversen's study for Nature, said the research dovetails with an upcoming article of his which concludes that the Arctic thawing is a combination of the two.

"If we didn't have the little extra kick from global warming then we wouldn't have gone past the threshold for the change in sea ice," said Overland, of the National Oceanic and Atmospheric Administration's lab in Seattle.

Other researchers said Graversen's study underestimates the effect of global warming because it relied on older data that stopped at 2001 and wasn't the most accurate.

Overland and scientist Mark Serreze disagree over which effect — man-made or natural — was the big shove that pushed the Arctic over the edge, but they agreed that overall it's a combined effort.

"Think of it as a boxer that's almost going down for the count ... and that one blow to the noggin comes and he's down for the count," said Serreze, a senior scientist at the government's snow and ice data center in Boulder, Colo.

Shifting heat layers above Arctic to blame for ice crisis: study

Marlowe Hood, Yahoo News 2 Jan 08;

The dramatic loss of the Arctic ice cap may have been triggered by disruption to the thermal layers of atmosphere stacked over Earth's far north, according to Swedish research to be published Thursday.

The study, published in Nature, offers a new explanation for the rise in the Arctic's surface temperature, which over the past century has been nearly two degrees Celsius (3.6 Fahrenheit), or twice the global average.

Until now, the big suspect in "Arctic amplification" has been reflectivity of sunlight.

When the Sun's rays hit snow or ice, most of that solar energy bounces back into space -- but as those melting surfaces give way to dark-blue sea, the heat is absorbed instead.

This self-reinforcing process, called a feedback, is an established factor in accelerating warming in snow and ice.

But Stockholm University scientists led by Rune Graversen believe a possibly bigger cause for Arctic warming could be changes in heat transport in the middle of the troposphere, an atmospheric band that extends 10 kilometers (seven miles) above Earth's surface.

In polar regions, the layers of relative heat above the surface are usually stable. But Graversen says that over the last two decades or so there have been changes in Arctic atmospheric circulation which have brought in heat and moisture.

The moisture is particularly important, as it helps form persistent low cloud over the Arctic.

Moisture-laden clouds at this altitude tend to absorb heat from the Sun, thus bringing a warming effect close to the surface. In contrast, high-altitude clouds, which mainly comprise icy crystals, reflect heat back into space, and thus cool the surface.

The circulatory shifts have an especially big impact in summer, says Graversen.

In 2007, summer sea ice in the Arctic shrank to about four million square kilometers (2.4 million square miles), a 23 percent decrease from the previous record low of 5.3 million square kilometers in 2005.

A second study, also in Nature, meanwhile, shows that the capacity of vegetation to absorb carbon dioxide (CO2) appears to be ebbing, with potentially serious consequences for global warming.

Currently, about 50 percent of all the CO2 produced by burning fossil fuels is soaked up -- "sequestered" -- by land masses, mainly through forests, and by oceans.

Remarkably, that percentage has remained stable even as the output of man-made greenhouse gases has increased.

Up to now scientists have assumed that longer growing seasons were a silver lining of climate change because the warmer temperatures gave photosynthesising plants more time to remove the most important of these gases -- CO2 -- from the atmosphere.

This view has been bolstered by satellite images showing a clearly visible "greening trend," notably in the northern hemisphere.

But Shilong Piao of France's National Centre for Scientific Research (CNRS), found that over the past 20 years the planet's biomass above the 20th parallel released nearly as much CO2 in the fall or autumn as it soaked up during the spring.

"If future autumn warming occurs at a faster rate than in spring, the ability of norther ecosystems to sequester carbon may be diminished earlier than previously suggested," he warns.

While Piao's study draws a clear link between rising temperatures and reduced carbon uptake, projecting future trends is very difficult, cautions John Miller, a expert on carbon cycles at the University of Colorado, in a commentary, also published in Nature.

California sues US for blocking car emissions rules

Yahoo News 2 Jan 08;

California said on Wednesday it was suing the US government for blocking the implementation of the state's tough new standards on greenhouse gases emitted by automobiles.

The move came after the Environmental Protection Agency (EPA) last month denied California's request to be allowed to set new vehicle emissions standards which would be more strict than the federal laws.

"It is unconscionable that the federal government is keeping California and 19 other states from adopting these standards," Governor Arnold Schwarzenegger said in a statement.

"They are ignoring the will of millions of people who want their government to take action in the fight against global warming," added Schwarzenegger.

"By implementing these standards, California would be eliminating greenhouse gases equivalent to taking 6.5 million cars off the road by the year 2020."

California's Attorney General Jerry Brown filed the suit Wednesday with the US Court of Appeals challenging the EPA's decision to block the law, which requires a 30 percent cut in greenhouse gas emissions from vehicles by 2016.

To institute emissions controls tougher than US national standards, California needs an EPA waiver, but last month agency administrator Stephen Johnson refused to grant one.

In a statement released December 19, the EPA said California had failed to show there were "compelling and extraordinary conditions" needed for a waiver.

"The denial letter was shocking in its incoherence and utter failure to provide legal justification for the administrator's unprecedented action," Brown said in a statement Wednesday.

"The EPA has done nothing at the national level to curb greenhouse gases and now it has wrongfully and illegally blocked California's landmark tailpipe emissions standards, despite the fact that sixteen states have moved to adopt them," Brown said.

Fifteen other states or state agencies were also joining California's suit, including Maine, Maryland, New Jersey, New Mexico, and New York.

"The EPA's attempt to stop New York and other states from taking on global warming pollution from automobiles is shameful," said New York Attorney General Andrew Cuomo.

"As recognized by the scientific community and most world leaders, global warming will have devastating impacts on our environment, health, and economy if it continues to go unchecked."

Brown said that in 40 years since the Clean Air Act had been passed the US government had never denied any of California's requests for waivers for instituting catalytic converters, exhaust emission standards, and leaded gasoline.

He pointed out that, according to EPA sources and media reports, Johnson rejected California's application against "the unanimous recommendation of his agency's legal and technical staff to grant the waiver."

In December the Los Angeles Times cited EPA staff in reporting that Johnson ignored his staff's recommendations on the waiver request.

In his statement, Brown said that the ruling "ignored the dangerous consequences of global warming to the State of California."

"Cars generate 20 percent of all human-made carbon dioxide emissions in the United States, and at least 30 percent of such emissions in California," he said.

"Global warming threatens California's Sierra mountain snow pack, which provides the state with one-third of its drinking water," he added.

Philippines townsfolk protect sea turtles

Townsfolk find connection between ‘pawikan,’ environment
Marlon Alexander Luistro, Philippine Daily Inquirer 2 Jan 08;

Sea turtles are essential to marine life since some of their species feed on jellyfish, algae and sea grass beds. “When there’s plenty of jellyfish, there would be less fish and it would no longer be desirable for someone to swim in the sea”

MANILA, Philippines – The people of San Juan, Batangas, weren’t able to make the connection between sea turtles, or pawikan, with a balanced ecology until the marine creatures made the town’s beaches a nesting place.

“Having a pawikan (around) is a manifestation of a balanced marine ecosystem,” said Ramon Flores whose group, Mother Earth, helped organize the release of 31 pawikan hatchlings into the Tayabas Bay on Dec. 15.

At about 5 p.m. of that day, residents of the town and youth leaders of Barangay Pinagbayanan, where the sea turtles laid eggs, released the hatchlings into the bay.

Rowena Sayat, a village resident who kept watch over the pawikan eggs, said she first found the hatched turtles at 3 a.m. on Dec. 13.

She said it took the turtle eggs at least 59 days to hatch and come off the sand.

Sayat is among the new recruits to a project that Flores’ Mother Earth has put together and which it calls Pawikan Pauwiin sa Karagatan (Return Pawikan to the Sea).

It seeks to preserve the country’s sea turtle population by sending sea turtles that stray into populated beaches, or lay eggs in these areas, back to where they belong.

Flores said ideally, pawikan hatchlings should be released within 12 hours to ensure their survival.

But Flores said his group bent the rules a little to invite more San Juan residents to a small ceremony of releasing the pawikans so the people could “learn the significance of preserving them.”

Yearly, the pawikan’s nesting period occurs from September to February, and depending on weather conditions, the pawikan eggs are expected to hatch from 45 to 60 days, he said.

Endangered

Before the turtles were released, Flores first gave a lecture to participants on the importance of preserving the pawikan in San Juan.

He said the sea turtles are essential to marine life since some of their species feed on jellyfish, algae and sea grass beds.

“When there’s plenty of jellyfish, there would be less fish and it would no longer be desirable for someone to swim in the sea,” he said in an interview, hours before the release.

Flores explained that there are four remaining pawikan nests in San Juan town, two each in Barangay Catmon and Barangay Pinagbayanan.

He expects the eggs in Pinagbayanan to hatch in the third week of December while those in Catmon in the middle of February.

Balayan sightings

Earlier, in the evening of Dec. 14, two fishermen in Barangay 9 in the town of Balayan found a sea turtle, measuring around 63 x 63 centimeters, which they suspected had formed a nest and laid eggs off the Balayan Bay coast.

Vilmor Gadon, president of the Anak Balayan (Ang Nagkakaisang Mamamayang Kostal ng Balayan), said residents Roco Oresa and Rico Bagay found the turtle at about 8 p.m.

The sighting was reported at least two days after the release of the 31 pawikan hatchlings at the Tayabas Bay.

Gadon identified the turtle species as Olive Ridley, which usually lays about 105 to 120 eggs in the cold months of September to February.

“We think that the turtle had just laid eggs but she got disturbed,” Gadon said in a phone interview.

He was referring to past experiences of people living in the Balayan Bay coast who observed that the pawikans form their nests anywhere from November and December.

Aside from Barangay 9, pawikan sightings have also been reported in the coastal villages of Palicpican, Barangay 10 and Sampica in Balayan.

He said their group would release the turtle after proper documentation and placing of tags by the Balayan Municipal Fishery Technologist and the Community Environment and Natural Resources Office-Calaca.

Gadon, however, said the trade of turtle eggs and meat threaten the pawikan population in the bay area.

Awareness

In the town of San Juan, the pawikan population has been declining since the 1970s due to the collection and trade of eggs which are being sold for P3 per piece.

Thanks to heightened public awareness and education, however, there may be hope for these sea creatures to multiply anew.

Marcel de Chavez, San Juan’s Bantay Dagat chair, said pawikan conservation has greatly helped small fishermen in the town.

“They are now able to catch 50 kilograms of assorted fish in the sea daily compared to a meager two kilograms in the 1990s,” De Chavez added.

“I’ve been living for 25 years here but it is only now that I’ve learned the importance of pawikan in sea life,” said 49-year-old Nonong Perpetua of Barangay Pinagbayanan in an interview.

Christia de Torres, a 15-year-old student from Joseph Marello Institute who joined the release in the same village, said youth leaders like her could help save the pawikans by monitoring their existing nests.

She vowed to impart the knowledge she acquired from Flores to the fishermen and other people in the community.

“Before, we don’t care about them. Now, if ever I will hear stories that a pawikan has been caught, I will tell the people involved to set them free,” Perpetua added.

Mother Earth’s project also seeks to make San Juan a model town that could contribute to the efforts of other local government units in the country in conserving turtles.

Endangered

Of the world’s seven pawikan species, five can be found in the Philippines.

Three of the country’s five pawikan species can be seen in San Juan—Hawksbill Turtle, Green Turtle, and Olive Ridley Turtle, which nest on the town’s sandy areas near the Tayabas Bay.

All three species are listed under Appendix One of the Convention on International Trade on Endangered Species.

This means that the “international commercial trade of these species are prohibited” and only “limited exchanges for scientific purposes are allowed.”

The Philippine Wildlife Resources Conservation and Protection Act, or RA 9147, prohibits the hunting, selling and killing, as well as collecting, of the eggs of endangered species like pawikan.

Problem with CNG refuelling station leaves taxi drivers stuck in long queues

Channel NewsAsia 2 Jan 08;

SINGAPORE: It was not a good start to the New Year for many Prime taxi drivers.

Many were stuck in long queues because there was a problem with the only compressed natural gas or CNG refuelling station, located on Jurong Island.

A dissatisfied group of taxi drivers gathered outside the Prime Taxis office on 2 Jan to meet their management.

Prime Taxis is one of the smallest and newest players in the taxi market, with just under 100 cabs using Compressed Natural gas or CNG.

The drivers said that on New Year's Eve, a problem developed with the pumps at the only CNG refuelling station on Jurong Island.

So a usually-10-minute wait to fill their CNG tanks with gas, became a two to three hour affair.

Taxi-driver Charan Singh, said: “Problem is that (when the) gas pump station breaks down, we cannot get gas (and) have to queue for 2 to 3 hours. One day too times how many hours I lose? How to continue driving like this? Now the fares are so bad and business is dull - how to manage the rental?"

Another taxi-driver, Tan Ah Kin, said:"We used to drive 10-12 hours one day - now at the very most you can drive 4-5 hours. So the waiting time is going to kill us."

What is worse is that the company has not raised its metered fares and won't do so for at least three months.

The company has only imposed the city surcharge from 1 Jan 2008 but most passengers don't know this.

So the drivers are suffering the same drop in business as other cab drivers by as much as 30 per cent.

In a statement, SembCorp Industries, which runs the CNG station, said one of its two compressors had an unusual malfunction and the spare part that is needed should arrive within a week.

In the meantime, the company is exploring all possible solutions and has advised some users to switch to petrol for now.

Prime Taxi management said it is still working out solutions to alleviate the taxi drivers’ woes.

This includes possible rental rebates and petrol vouchers.

Mr Tan Soon Chye, General Manager of the Taxi Division for Prime Car Rental and Taxi Services, said: “While the gas company is doing their best to rectify the situation, we at Prime Taxis had a dialogue with taxi masters and we have worked out a package to alleviate their problems at this time while the pump is undergoing repair."

One of the main problems that has left taxis idling is that there is only one CNG refuelling station in Singapore which is located on Jurong Island.

However, three more such refuelling stations are expected to open throughout the rest of the year with the next one expected to open in about two weeks time. -CNA/vm

Gas glitch, low takings mean double whammy for Prime taxis
Ng Jing Yng, Today Online 2 Jan 08;

For drivers with Prime Taxis, it is a New Year to forget. Not only have their takings slid since fares were hiked, but they are now seeing red over fuelling problems.

Since Monday, its fleet of taxis, which run on compressed natural gas (CNG), have been held up by a breakdown at the CNG station on Jurong Island.

A fault in one of the two compressors at Singapore's only CNG pump station has meant queues of up to three hours — instead of the usual 10-minute wait — for nearly 100 taxi drivers and 200-plus owners of private CNG cars.

"Each day, refill two times — how many hours do I lose? How to continue driving like this?" taxi driver Charan Singh told Channel NewsAsia.

Another driver, Mr Tan Ah Kin, told the channel: "We used to drive 10 to 12 hours one day, now at the very most you can drive four to five hours. The waiting time is going to kill us."

The alternative for most is to pay for more expensive — and environmentally less friendly — fuel such as petrol, which is twice as costly as CNG.

SembCorp Industries, which oversees the station, told reporters that the issue would take about a week to resolve, when spare parts arrive from Germany.

It advised owners of heavy vehicles and private cars not to take their vehicles to the station, to give taxi drivers priority.

The refuelling woes add to another financial burden for the taxi drivers — a sharp drop in their earnings since taxi fares first went up on Dec 17.

Despite being the sole taxi operator not to raise its flagdown rate to $2.80 — Prime Taxis followed only the new CBD surcharge of $3 from Jan 1 — its drivers saw a similar drop in passenger numbers as their ComfortDelGro counterparts, which this newspaper first reported last month.

Prime taxi driver Ong Lye Chor, 43, told Today: "Even though it was the holiday season, my earnings have dropped about 50 per cent, and now this fuel problem …"

A compensation package comprising fuel vouchers and rental rebates of 10 per cent this month is being worked out as a temporary relief for the double whammy, said Mr Tan Soon Chye, general manger (taxi division) at Prime Car Rental and Taxi Services, after drivers called for a meeting with the company.

But he insisted that the three-month old firm would stand by its "commitment to the public" not to increase fares from until March — which has elicited a mixed response from drivers.

Despite the distinctive bright copper tinge of its taxis, some drivers doubt the public is aware of the move or if it makes a difference.

One taxi driver said his friends had even resorted to displaying a "$2.50" sign to attract passengers, but in vain.

Others, however, such as Mr Lie Chee Kiang, 39, said: "Looking at the current situation now, more passengers are just going to stay away if Prime increases their fares as well."

Singapore hospitals may get first robotic seals as pet therapy

Channel NewsAsia 2 Jan 08;

SINGAPORE: You've heard of pet therapy - where dogs and cats are brought to hospitals and nursing homes to cheer the sick or elderly. But robotic pet therapy?

Well, Singaporeans will get to meet the latest robotic seals from Japan - at Asia Pacific's first Silver Industry Conference and Exhibition (SICEX) to be held from 10 to 13 January at Suntec City.

96-year-old Madam Loo Chay has not laughed so hard in a long time and it's all thanks to robotic seal Paro - which means robot in Japanese.

The furbot winks when its name is called, wriggles when petted and shows displeasure when ignored!

The US$4,000 robotic pet has some 30 tactile, visual, audio and posture sensors under its soft artificial anti-bacterial fur. It can mimic animal behaviour over time, and even develop its own personality.

And its healing effects were recognised by the Guiness Book of World Records. Paro is officially certified as the "World's Most Therapeutic Robot" - for its psychological, physiological and social effects on physical interactions.

Dr Edwin Lim, Physician Manager of Orange Valley Nursing Home, said: "Animal-assisted therapy is an integral part of the therapy programmes of many residential aged care facilities.

"And such therapy has been shown to reduce blood pressure, decrease agitation and improve social interaction among dementia patients. Robotic pets can (also) replicate such therapy as live animals."

Most hospitals and nursing homes do not allow pets, especially in the wards, for fear of possible negative effects of the animals to the patients, such as allergies, infections, biting and scratching.

But with robotic pets such as Paro, there are no such worries and the best part is that they require minimal maintenance, yet they are always available for pet therapy on demand.

Mr Lim continued: "For volunteers bringing their pets in, we have to actually organise events around their schedule, once a month or twice a month - so it depends on when they're free to come after work. Most of them have their full-time jobs.

"Having a robot here (and) switching it on many times, whenever we have new cases coming in or agitated behaviour showing up, we can bring this out to calm them."

Now into its eighth generation since it was developed in Japan, the latest model can be programmed to recognise seven different languages - Chinese, English, French, Japanese, Korean, Portuguese and Spanish. - CNA/vm

Australian corals might migrate south: scientists

The Age 2 Jan 08;

Global warming may result in tropical corals migrating south, Australian scientists say.

The Centre of Excellence for Coral Reef Studies says the western seaboard between Perth and Geraldton could end up with coral reefs as rich and varied as the celebrated reefs of Ningaloo in the north-west.

The centre's researcher, Professor John Pandolfi, and Professor Benjamin Greenstein of Cornell College, Iowa, USA, worked from fossil evidence of what happened in West Australian waters during a warm phase in the global climate 125,000 years ago.

Their findings, published in the international journal Global Change Biology, concluded that tropical corals could soon head south once more to escape warming oceans.

"Back then there used to be rich coral reefs dotted all along the WA coastline, from south of Perth to north of Dampier," Prof Pandolfi said in a statement.

"When the seas cooled with the onset of the most recent ice age, many of the corals contracted north."

The result was that there are two distinct coral communities - the rich and beautiful one capable of reef growth from places like Ningaloo, and a far simpler community with fewer species scattered on rocky outcrops in the cooler waters of the south.

Prof Pandolfi said that with oceans warming again due to the greenhouse effect, the rich, diverse northern corals are likely to spread south again, travelling on the Leeuwin current, in search of places to survive global warming and avoid impacts such as bleaching and coral disease which occur when tropical waters warm too much for them to tolerate.

He said WA had suitable shallow habitats for tropical corals to settle in, whereas south of the Great Barrier Reef there were few suitable areas for corals to move south.

"The water is mostly too deep," Prof Pandolfi said.

Philippine rebels raid mine to stop "plunder"

Reuters 2 Jan 08;

MANILA (Reuters) - Communist rebels in the Philippines said on Wednesday they attacked a mine majority-owned by Xstrata Plc to "punish" the Switzerland-based firm, protect the environment and safeguard the rights of local tribes.

About 30-40 armed men raided the Tampakan mine in the southern Philippines on Tuesday morning and burned six buildings, police said. They said the rebels were from the Communist New People's Army (NPA).

Officials at the mine said the attack would not affect a pre-feasibility study now in progress.

Tampakan is one of the biggest undeveloped copper resources in Southeast Asia. Its total resources are estimated at 12.8 million tons of contained copper and 15.2 million ounces of contained gold.

"As the people intensify their struggle to assert national patrimony against the rapacity of foreign monopoly capitalists, the New People's Army will carry out more and more punitive actions in response to the people's demands to stop the unbridled rapacious and destructive operations of big foreign mining companies," a statement from the Communist Party of the Philippines said on Wednesday.

"Yesterday's raid is an important milestone in the effort to put a stop to the firm's destructive and plunderous mining operations, defend the ancestral domain of the B'laan tribe; protect the environmental balance and resist the Arroyo regime's campaign to auction off the country's natural resources to big foreign capitalists."

The government of President Gloria Macapagal Arroyo has called for a ceasefire with the Communist rebels over the holiday season.

The rebels opened fire on a nearby army detachment during the raid but there were no casualties, police said. The rebel statement said the firing was only a deterrent and that the NPA did not pursue the offensive in deference to the ceasefire.

Tampakan is due to launch production in 2013, with annual output of 200,000 tons of copper and 200,000 ounces of gold.

The mine is 62.5 percent owned by Xstrata and 34 percent by Australia's Indophil Resources N.L..
