Sharks saved from soupy fate set free at sea

Didier Lauras (AFP) Google News 6 Sep 11;

PATTAYA, Thailand — Saved from the soup bowl at a Thai restaurant, the baby shark wriggled out of the bag and into the open sea -- a rare survivor of a trade that kills millions of the predators each year.

On average an estimated 22,000 tonnes of sharks are caught annually off Thailand for their fins -- a delicacy in Chinese cuisine once enjoyed only by the rich, but now increasingly popular with the wealthier middle class.

Thanks to a group of environmental activists calling themselves the Dive Tribe, dozens of sharks were returned to the wild in the Gulf of Thailand recently, bought from animal markets or restaurants.

Among them were several young bamboo and black tip reef sharks which narrowly avoided ending up as shark fin soup -- prized in particular by the Chinese who believe it boosts sexual potency.

Gwyn Mills, founder of Dive Tribe, laments the fact that the plight of sharks is largely overlooked compared to animals such as elephants and tigers.

He fears it may be only five or 10 years before the damage is irreversible.

"We are losing too many sharks. We can't afford to take any more out of the ocean," Mills said.

Scientists blame the practice of shark-finning -- slicing off the fins of live animals and then throwing them back in the water to die -- for a worldwide collapse in populations of the predators, which have been swimming since the time of the dinosaurs.

The maritime conservation group Oceana estimates that up to 73 million sharks are finned each year around the world, depleting many populations by as much as 90 percent.

Although the shark is portrayed as an insatiable man-eater in Steven Spielberg's hit 1975 movie "Jaws", naturalists say most species pose no danger to humans.

"Actually attacks on people are rare," said Jean-Christophe Thomas, a scuba instructor involved in the shark release.

On Saturday, 60 sharks left their temporary home at the "Underwater World" aquarium in the Thai resort city of Pattaya in plastic bags filled with water. Loaded onto a boat, they were released one by one back into the wild.

"I was carrying the plastic bag and did not even notice when he left," said Wayne Phillips, a lecturer in marine ecology at Mahidol University.

"But I like that. He was not given freedom. He took it. He was living in a tank, then in a plastic bag. He's better here."

While the release was a largely symbolic event designed to raise awareness, the stakes are real.

Environmentalists say that sharks, particularly the apex predators, play a vital role in the marine ecosystem.

"So if we protect the sharks, the rest of the reef will be protected," said Phillips. "We need to make people realise how important sharks are."

Environmentalists argue that sharks are slow to reproduce, making them unsuitable for commercial fishing.

Some types of shark species, including the great white and the hammerhead, are endangered, threatened or vulnerable, according to the International Union for the Conservation of Nature.

Some countries are taking action.

The tiny Pacific nation of Palau declared the world's first shark sanctuary in 2009, prompting similar moves by the Maldives and Honduras.

Taiwan, one of the world's major shark catchers, is moving to tighten measures against hunting the predator while the Malaysian state of Sabah on Borneo island is also seeking to ban shark fishing.

The members of the Convention on International Trade in Endangered Species (CITES) also adopted a resolution in 1994 on shark conservation and management.

And in 1999, the UN Food and Agriculture Organisation adopted an International Plan of Action for the Conservation and Management of Sharks.

But a report by the wildlife trade monitoring network Traffic and the Pew Environmental Group released in January said not enough was being done to implement that plan.

"International concern about shark stocks continues to grow because of an increasing body of evidence that many shark species are threatened and are continuing to decline as a result of unregulated fishing", it said.

Activists believe the best hope of reversing the situation is to highlight the benefits of sharks to the tourism industry.

The animals are a major attraction for snorkelers and scuba divers, but it is increasingly rare to see the creatures in the seas off Thailand.

Mills argued that one reef shark is worth many times more to the tourist industry than it would fetch in a restaurant. He thinks fishermen should be compensated for releasing the sharks that get entangled in their nets.

While swimming with sharks is a joy for many scuba divers and naturalists, for some the shark remains a creature to be feared -- an image unlikely to be helped by the upcoming release of the Hollywood movie "Shark Night 3D".

The film tells the fictional story of a group of carefree teenagers killed off one by one by hungry sharks in a salt lake in Louisiana.

According to the International Shark Attack File, compiled at the University of Florida, 79 unprovoked shark attacks occurred around the world in 2010, six of which were fatal. This was the highest number in a decade and an increase of 25 percent on 2009.

For Dive Tribe and other shark lovers, the battle is only just beginning.

Alien worm invasion 'threat to forests'

Mark Kinver BBC News 6 Sep 11;

Invasive earthworms can alter the carbon and nitrogen cycles in woodland, as well as undermining native plant species, a study has said.

US researchers found that the presence of non-native worms also accelerated the breakdown of forest litter, increasing the risk of soil erosion.

The worms are spread to new areas by horticulture and land disturbance, they add, as well as on vehicles' tyres.

The findings have been published in the journal Human Ecology.

"The presence of earthworms in temperate hardwood forests may accelerate decomposition of forest litter, which potentially reduces habitat for forest-floor animals, (increases) soil erosion... and affects carbon and nitrogen cycles," the researchers from Colgate University, New York, wrote.

Quoting a previous study, the scientists said that invasive earthworms could reduce the amount of carbon stored in soil by up to 28% as a result of the animals eating fallen leaves, which had a knock-on effect on the temperature of the forest floor.

Dark soil absorbed more solar energy than lighter leaf litter, causing the soil to dry out more quickly.

As well as altering the chemical composition of soil, the worms also had an biological impact because the thinner layer of litter reduced populations of a number of forest-dwelling flora and fauna, such as small mammals, ground-nesting birds and some threatened fern species.

The team, whose study focused on the forests of north America, suggested that there were a number of factors behind the dispersal of non-native worms across the landscape.

These were primarily the result of human activity, because after being wiped out in the region during the last period of glaciation, earthworms would have made a very, very slow advance northward, covering just a few hundred kilometres over the past 10,000 years.

The shipping and transplantation of soil in the horticulture industry is believed to be one factor.

The researchers also said that previous research had shown a strong correlation between the presence of roads and the number of worms found in the area, probably the result of the combination of soil disturbance and worms being dispersed by vehicles.

As well as the unintentional spread, the team indentified a number of "intentional" vectors. One was the use of Lumbricus rubellus (red earthworm) in community compost heaps.

But the biggest problem came from the disposal of fishing bait, which the researchers described as "the most important vector for widespread and scattered exotic earthworm introduction in remote areas".

Although Lumbricus terrestris (common earthworm) is native to temperate regions of Europe, it is considered to be an invasive species in North America as it thrives in agricultural marginal land and is deemed to inhibit the growth of native flora in these areas.

Yet within parts of Europe, the common earthworm itself is struggling to compete against flatworms that were introduced from Australasia.

Carbon casts

However, a study published earlier this year that examined the role of worms in the carbon cycle of tropical forests found the creatures had a net benefit in terms of locking carbon into the soil.

Within an area of rainforest in Vietnam, the researchers found that casts (excretions of digested organic matter) produced by a species of worm had higher concentrations of carbon, and were able to withstand about twice as much rainfall, than surrounding "control" soil samples.

As a result, the team concluded that the presence of worms enhanced the transition of organic material into soil aggregates.

Soils with many aggregates (clumps of soil particles and a mixture of organic and fungal matter) are considered to be more stable and less prone to erosion.

Giant crabs make Antarctic leap

Richard Black BBC News 6 Sep 11;

King crabs have been found on the edge of Antarctica, probably as a result of warming in the region, scientists say.

Writing in the journal Proceedings B, scientists report a large, reproductive population of crabs in the Palmer Deep, a basin cut in the continental shelf.

They suggest the crabs were washed in during an upsurge of warmer water.

The crabs are voracious crushers of sea floor animals and will probably change the ecosystem profoundly if and when they spread further, researchers warn.

Related species have been found around islands off the Antarctic Peninsula and on the outer edge of the continental shelf.

But here the crabs (Neolithodes yaldwyn) are living and reproducing in abundance right on the edge of the continent itself.
Search for life

The researchers sent the Genesis, a submersible remotely operated vehicle (ROV) operated by the University of Ghent in Belgium, into the Palmer Deep in March last year.

The idea was to look at what life was down there, rather than specifically to look for crabs; and the team was somewhat surprised by how many they found.

Judging by the density of the crabs and their tracks, the scientists estimate there may be 1.5 million crabs in the basin.

A female crab retrieved from the area was found to be carrying mature eggs and larvae.

"Our best guess is there was an event, or maybe more than one, where warmer water flushed up across the shelf and carried some of the larvae into the basin," said project leader Craig Smith from the University of Hawaii.

It is believed that this species cannot tolerate water colder than 1.4C.

The seas here get warmer as you descend; and the crabs were only found below 850m.

The researchers calculate that they have probably been there only for 30-40 years; before that, the water would have been too cold even at the bottom of the Palmer Deep.

They cannot as yet survive on the continental shelf, which is at a depth of about 500m; but that could change.

"If you look at the rate at which the seas are warming, (the continental shelf) should be above 1.4C within a couple of decades, so the crabs are likely then to come into shallower waters," Professor Smith told BBC News.
Predators

The upper limit of the crab-dwelling zone - 850m - also marks the line between abundant seabed life above and depleted life below.

"Above the crab zone, the abundance and diversity of plants and animals was high, with echinoderms including brittlestars, sea lilies and sea cucumbers," said Professor Smith.

"We found none of them in the crab zone itself, and when we went 50-100m above we found very few - so we think the crabs are venturing up into shallow waters to feed.

"We would expect extinctions in some of these organisms."

These findings reinforce the belief of other scientists that king crabs will change the ecology of the Antarctic perimeter once they arrive - and that they would arrive at some point, washed from warmer waters along the South American coast, has long been expected.

With a legspan of up to a metre, the animals are generally top predators in the seafloor ecosystem.

The king (or stone) crabs are a group of about 120 species - and one member, the red king crab (Paralithodes camtschaticus) is already having an ecological impact in Norwegian waters following its slow spread from Russia.

However, in Northern latitudes they are also now important commercially, with Norwegian fishermen alone allocated a quota of thousands each year.

Fishing crabs for profit in this part of the Antarctic would not be permitted. But fishing could in time be used as a means to control them, said Professor Smith, if their ecological impacts become too severe.

Global warming brings crab threat to Antarctica
AFP Yahoo News 7 Sep 11;

The sea floor around the West Antarctica peninsula could become invaded by a voracious king crab, which is on the march thanks to global warming, biologists reported on Wednesday.

The worrisome intruder is a bright-red deep-sea predator that previously had been spotted only in the Ross Sea, on the other side of West Antarctica.

Taxonomists identified the crustacean just five years ago, bestowing it with the lengthy monicker of Neolithodes yaldwyni Ahyong and Dawson and placing it among the 121 species of king crab.

It is known as an "ecosystem engineer" because it digs into the sea floor to feast on worms and other tiny animals, an activity that in large numbers can have repercussions across the marine food web.

A team led by Laura Grange of the University of Hawaii at Manoa lowered a remote-controlled scoutcraft as part of a long-term probe into biodiversity in the waters off the Antarctic peninsula.

They looked at Palmer Deep, a mud-floored basin in the Weddell Sea located 120 kilometres (75 miles) from the edge of the continental shelf.

The robot's camera, trailed over two kilometres (1.2 miles), spotted 42 crabs, all of them at depths lower than 850 metres (2,760 feet), where the water was a relatively balmy 1.4 degrees Celsius (34.5 degrees Fahrenheit).

By extrapolation, the crab population in Palmer's deep -- an area measuring 14 kms (nine miles) long by eight kms (five miles) wide -- could be more than 1.5 million, says Grange.

That density is the same as commercial crab fisheries in Alaska and the British South Atlantic island of South Georgia.

The images gave a glimpse of the kind of damage caused by the foraging crustaceans.

The crabs, their shells measuring roughly 10 centimetres (four inches) across, had dug gashes up to 20 cms (one foot) into the soft ocean floor and thrown up lumps of sediment. The robot also retrieved a pregnant female crab, as proof that the species was reproducing.

None of the crabs was found at shallower depths, where the seas are colder.

The implication is that as global warming heats the frigid coastal-shelf waters, which lie at depths of 400 and 600 metres (1,300 and 1,950 feet), the way will be open for the crustacean to continue its creeping advance.

The evidence from sea-floor sediment is that no so-called lithodid, or crushing, crabs have inhabited the cold shallow waters of the West Antarctic peninsula for 14 million years.

Previous research has already named the peninsula as one of the most vulnerable regions in the world for global warming. The waters of its continental shelf are warming at the rate of 0.1 C (0.14 F) per decade.

"If N. yaldwyni is currently limited by cold temperatures, it could spread up onto the shelf within one to two decades," warns the study, published in the British scientific journal Proceedings of the Royal Society B.

Valuing Nature’s Services Today Is an Investment in the Future

New article identifies ways in which payments for ecosystem services (PES) help protect biodiversity and mitigate climate change
World Watch Institute 6 Sep 11;

Washington, D.C.—Countries around the world are embracing “payments for ecosystem services” (PES) as a verifiable approach to protecting biological diversity and mitigating climate change, according to research conducted by the Worldwatch Institute for the publication Vital Signs Online. PES are financial arrangements designed to protect the many benefits that are provided by the natural environment. They include payments for projects that invest in biodiversity and watershed protection, ecosystem restoration, and carbon capture in forests.

“Nearly 60 percent of all ecosystem services are being degraded or used in an unsustainable manner,” said Alexander Ochs, Director of Climate and Energy at Worldwatch. “With PES, we can put a monetary value on these important services, from water filtration to carbon sequestration, to ensure that they are being properly sustained for the benefit of both people and the planet.” PES schemes aim to encourage a net increase in benefits that would not otherwise have occurred without the financial incentive, a concept known as providing “additionality.”

At the international level, two initiatives—the United Nations’ Reducing Emissions from Deforestation and Forest Degradation (REDD) Programme and the World Bank Forest Carbon Partnership Facility—were established in 2008 to assist in the development of a global PES scheme that would compensate developing countries for their efforts to conserve tropical forests, which act as important carbon “sinks.” The international community has discussed scaling up REDD finance to $30 billion per year. Several wealthier governments, including Norway and Germany, are providing funds to help developing countries build the capacity to handle a REDD market as well as to provide financial incentives to the best performers.

In the absence of a fully defined REDD marketplace, the primary markets for ecosystem services are currently in the areas of watershed and biodiversity protection, with a combined global value of at least $11 billion in 2008. The largest national markets for services to protect and enhance water quality are China and the United States, respectively.

Worldwide, payments for biodiversity totaled $2.4 billion to $4 billion in 2010. Although PES growth has slowed in countries that already have programs in place for biodiversity protection, other countries are adopting new programs and policy frameworks for biodiversity payment mechanisms. “In 2010, at least 45 payment programs for biodiversity were operational across the world and 27 programs were in development,” said Will Bierbower, the author of the article and a former Climate and Energy researcher at Worldwatch.

Factors driving the development of PES schemes include the scale of the ecosystem service being provided, the number of buyers and sellers involved, and the degree to which there is an immediate financial payoff. The design of a PES arrangement is shaped in part by the prevailing political, cultural, and institutional arrangements in a country or region; however, governments have typically been the key players in establishing most PES arrangements.

“China’s Sloping Land Conversion Program is a good example of a government-backed PES scheme that was enacted in tandem with regulations,” said Bierbower. “In 1999, the government started paying farmers to restore land to its original ecological state, following decades of mismanagement that had led to topsoil erosion and downstream flooding. In the first seven years, rural farmers received some $7.7 billion in payments and enrolled some 7.2 billion hectares of cropland in what has become one of the largest PES schemes in the world.”

Further highlights from the article:

=Globally, payments for watershed services that protect and enhance water quality were worth an estimated $9.25 billion in 2008.
=Payments for biodiversity protection, restoration, and management were worth an estimated $1.8 billion to $2.9 billion in 2008. By 2010, these payments had reached $2.4 to $4 billion worldwide.
=PES carbon sequestration projects in the world’s forests were worth an estimated $37 million in 2008, up from $7.6 million in 2006.
=The volume of transactions for carbon sequestration projects in forests increased from 5.1 megatons of carbon dioxide in 2007 to 5.3 megatons in 2008.
=In the United States, PES transactions total $1.5 billion to $2.4 billion annually.
=Deforestation, which occurs primarily in tropical forest regions, accounts for an estimated 12–20 percent of human-caused greenhouse gas emissions.

Banned livestock drug continues to threaten India's vultures, conservationists warn

Diclofenac is still being sold despite causing population crashes in species of vulture that fed on cattle treated with the medication
Press Association guardian.co.uk 6 Sep 11;

Conservationists have raised concerns that a livestock drug banned in India because it was pushing vultures to the brink of extinction is still being sold.

The drug diclofenac was banned because it led to population crashes in three species of vulture in south Asia with birds dying of kidney failure after feeding on carcasses of cattle treated with the medication.

A study led by the RSPB's principal conservation scientist, Richard Cuthbert, found more than one-third of Indian pharmacies are still selling diclofenac, a non-steroid anti-inflammatory drug, which can be used in humans as well as by farmers treating cattle.

Some of the diclofenac on sale is formulated for veterinary use and has been manufactured illegally since the ban was brought in by India, Pakistan and Nepal, the research published in the journal Oryx found (PDF).

The RSPB said the research, conducted to examine the effectiveness of the banning of the drug in 2006 in India followed by further measures in August 2008, showed that oriental white-backed, long-billed and slender-billed vultures were still at risk.

The white-backed vulture has seen its numbers drop by 99.9% since 1992, from millions to 11,000, while populations of the other two species have fallen by 97%.

In some good news for the species, the research found there was an increase in use of another drug, meloxicam, which was found in 70% of pharmacies and has similar treatment properties for cattle.

Captive breeding centres in India run by the Bombay Natural History Society, with support from the RSPB and the Save campaign, have had their most successful year so far, with 18 birds successfully reared in 2011, almost double the number last year.

But Cuthbert said: "The ban is still quite easy to avoid because human formulations are still freely for sale in large vials which are convenient for use on large animals like cattle and clearly not suitable for human use.

"Preventing the misuse of human diclofenac for veterinary use remains the main challenge in halting the decline of endangered vultures."

Chris Bowden, head of the RSPB's vulture programme, said: "Three species of south Asia's vultures are heading for extinction so we have to act now to save them.

"With the latest success of the breeding centres we're more confident than ever that there will be sufficient numbers for reintroduction to the wild as soon as it's safe for them, but until diclofenac stops being produced and sold for veterinary use we cannot guarantee these birds have any future in the wild."

Bangkok at risk of sinking into the sea

Parts of Thailand's capital could be under water by 2030 unless the government takes steps to prevent disaster, say experts
Bruno Philip Guardian Weekly 6 Sep 11;

Among the pressing challenges facing the new government of Thailand, brought to power by the 3 July elections, is the inescapable fact that Bangkok is steadily sinking. The gloomiest forecasts suggest parts of the Thai capital may be underwater by 2030, but experts are also critical of the lack of any clear policy to prevent impending disaster.

Several factors – climate change, rising sea level, coastal erosion, shifting clay soil – are threatening the great city on the Chao Phraya delta, founded in April 1782 by the first monarch belonging to the Chakri dynasty, still ruling today.

The population has greatly increased, with about 10 million people now living in the city and its suburbs. Even the weight of the skyscrapers, constantly on the rise in a conurbation in the throes of perpetual change, is contributing to Bangkok's gradual immersion. Much of the metropolis is now below sea level and the ground is subsiding by 1.5 to 5cm a year.

In the medium to long term more than 1m buildings, 90% of which are residential, are under threat from the rising sea level. In due course the ground floors of buildings could be awash with 10cm of water for part of the year, according to the Asian Institute of Technology.

In the port of Samunt Prakan, about 15 km downstream from the capital, the residents of detached houses along the river already spend several months a year up to their ankles in water.

A joint report published in December by the World Bank, the Asian Development Bank and Japan's International Co-operation Agency highlighted the threat from climate change to three Asian mega-cities: Bangkok, Ho Chi Minh City, and Manila.

Illegal tapping of groundwater is one of the causes of the capital's misfortunes, according to Jan Bojo, a World Bank expert based there. Not all the specialists endorse this view, but they do agree the situation is bound to deteriorate over the next few years. Smith Dharmasaroja, the head of the National Disaster Warning Centre, is predicting that by 2100 Bangkok will have become a new Atlantis. However gloomy this may seem, Dharmasaroja's forecasts are taken seriously. In the 1990s he predicted the fearful tsunami which devastated countries round the Indian Ocean in 2004.

Dharmasaroja maintains that "no decision has been taken" at government level "to stop the problem". And, he adds, if nothing is done Bangkok could be underwater by 2030.

One of the solutions he has suggested is to build a series of dykes along the coast of the Gulf of Thailand, a scheme which would cost well over $2bn. He says work should start immediately, otherwise it will be too late to halt the chain of events leading to disaster.

Anond Snidvongs, an oceanographer and specialist on climate-change impacts in southeast Asia, takes a more cautious line. "No one can predict how long it will take for Bangkok to be flooded and how this process will unfold," he says. He sees no point in building huge dykes. "The rise in sea level is not that great and climate change only plays a fairly small part – about one-fifth – in the current scenario," he adds.

"It's pointless," he stresses, "to try to protect the coastline which is being eroded by three to four centimetres a year. But there are plenty of other ways of combating flooding, such as better management of building land in the city."

Niramon Kulsrisombat, a town planner and lecturer in urban and regional planning at Chulalongkorn University, confirms that "floods have always occurred, Bangkok having been built on sodden terrain 1.5 metres below sea level".

A network of khlongs (canals), fields and allotments used to soak up flooding, but with recent urbanisation many buildings have taken their place and the water is trapped.

"Government efforts have focused on raising barriers 2.8 metres high along various stretches of the Chao Phraya," Kulsrisombat explains, "but this has just done even more damage to the traditional appearance of a settlement where people lived on the water in houses on stilts."

Snidvongs thinks the key factor in saving the city is coordinating measures taken by the authorities. "We absolutely need to achieve a consensus so that the million or so people who will be directly affected by flooding in the medium or long term can agree on the principles underpinning any solutions," he says. "Basically it is not a technical or financial issue. The specialists also need to agree on accurate figures providing a consistent picture of what the future holds."

In short the scientists who spend their time scrutinising Bangkok must tighten up their diagnosis, the better to prepare for rescuing the Thai capital.

In The World's Breadbasket, Climate Change Feeds Some Worry

Christine Stebbins PlanetArk 6 Sep 11;

The United States, the breadbasket and supplier of last resort for a hungry world, has been such an amazing food producer in the last half-century that most Americans take for granted annual bounteous harvests of grain, meat, dairy, fruits, vegetables and other crops.

When horrific images of drought or famine in Africa, Asia or other regions land in American media, America is usually first in line with food aid shipments, air drops, and other rescue efforts from its seemingly endless stores.

The U.S. alone accounts for half of all world corn exports, 40 percent of soybean exports and 30 percent of wheat exports. But climate change fears are sounding some warning bells.

Some scientists and agronomists are becoming increasingly concerned about the real effects they see now on growing conditions in the Midwest, the vast black-soiled region long the core region of the U.S. agricultural miracle.

They also say that not only skeptical farmers but also government authorities are trying to quietly adapt, from equipment to planting to research.

"We don't have a long-term reserve. We have a global food supply of about 2 or 3 weeks," said Eugene Takle, Professor of Agricultural Meteorology and Director of the Climate Science Program at Iowa State University.

"We've become insensitive to climate -- with air conditioning, irrigation and better practices," he said. "Well, I think we need to rethink that. Just how vulnerable are we?"

Takle and others say the future is now.

"It's not the long-term climate trends," Takle says, "It's the variability. It's the extreme events that have brought the vulnerability of agriculture to climate into the forefront. We think about, and wring our hands for awhile."

Jerry Hatfield, Laboratory Director at the National Soil Tilth Laboratory in Ames, Iowa, has worked with other scientists in research for the United Nations Intergovernmental Panel on Climate Change. He says climate change is occurring right now, as is adaptation to it, in the U.S. farm belt.

"We don't have to think about 2030 or 2050, in the recent memories we've had a lot more variability in our weather," Hatfield said. "This increasing variability of weather, which is associated with our changing climate scenarios, is going to continue to increase the variability in production.

"That's what concerns a lot of us," Hatfield said.

GOVERNMENT FUNDING RESEARCH, FARMERS ADJUSTING

The IPCC, which has been attacked by climate change skeptics, concluded in 2007 that increased frequency of heat stress, droughts and floods are "creating the possibility for surprises, with impacts that are larger, and occurring earlier, than predicted using changes in mean variables alone."

"Climate variability and change also modify the risks of fires, pest and pathogen outbreak, negatively affecting food, fiber and forestry," the Panel said.

Despite the attacks by skeptics, IPCC's conclusions have been accepted as valid by institutions like the U.S. National Academies of Sciences.

In June 2009, the science academies of the G8 countries, plus Brazil, China, India, Mexico, and South Africa, demanded action to address global climate change that "is happening even faster than previously estimated."

Takle said Midwest farmers are already adapting.

"Farmers say they don't believe in climate change, but you look at how they spend money and are adapting," he said.

Takle pointed to bigger machinery to allow faster and denser seeding amid rainier springs in the Midwest. Frosts are trending later so crops are kept in fields longer to dry.

But many of the changes are more subtle and hidden than the weather events that grab the headlines, like the massive wildfires, flooding and tornadoes that have hit agricultural areas of the Midwest, Plains and Southwest this year.

Takle said measurable trends of more humidity, for example, has led to higher night-time summer temperatures in the Corn Belt and likely trimmed corn yields in recent years. Corn likes hot days but cool nights.

In Iowa, dew point temperatures have risen 3-1/2 degrees Fahrenheit in the last 35-40 years, equating to 13 percent more moisture in the air during the summertime, he said.

"It's very important that we recognize the vulnerability," Takle said. "We have situations like in Texas. Huge reservoirs have just vanished. You can't do a work around."

The U.S. Agriculture Department this year issued its first grants to study crops and climate change.

"If you're interested in adapting to changes in climatic norms you need to have access to diversity," said Randy Wisser of the University of Delaware, who will study the genetics in exotic tropical maize to see how this might help farmers.

Other grants will address greenhouse gas emissions that affect climate, notably methane from livestock and carbon dioxide from growing crops.

"We are just trying to find a suitable way to keep these farmers in business. It took generations to create the problem it will take generations to fix the problem," said William Horwath of the University in California, who will develop strategy for rice growing in the Sacramento-San Joaquin Delta.

"It's a pretty darn complex problem," Hatfield said. "We poke at it, but we need to get very serious about how do we think about adapting our crop production goals to the concepts of variability."

US counts the cost of nine months of unprecedented weather extremes

According to the National Oceanic and Atmospheric administration, there have been 10 major disasters this year
John Vidal guardian.co.uk 5 Sep 11;

As deadly fires continue to burn across bone-dry Texas and eight inches of rain from tropical storm Lee falls on New Orleans, the US is beginning to count the cost of nine months of unprecedented weather extremes.

Ever since a massive blizzard causing $2bn of damage paralysed cities from Chicago to the north-east in January, nearly every month has been marked by a $1b+-weather catastrophe. According to the National Oceanic and Atmospheric administration (Noaa), there have been 10 major disasters already this year, leaving more than 700 people dead and property damage of over $35bn (£22bn).

In the past 31 years the mainland states have suffered 99 weather-related disasters where overall damages and economic costs were over $1bn. This year has seen three times as many than as usual.

Noaa will release its August data next week but Summer 2011 is expected to be the warmest on record. Chris Burt, author and leading weather historian, has complied a list of more than 40 cities and towns that have experienced record temperatures this year.

"So many heat records of various types have been shattered this past summer that it is impossible to quantify them," he said. "Not since the great heat waves of 1934 and 1936 has the US seen so many heat-related records broken as occurred this summer. The back-to-back nature of the intensity of the past two summers should raise some interesting questions, questions I am not qualified to address."

This year, the UN World Meteorological Organisation said 2010 was the warmest year on record, confirming a "significant" long-term trend of global warming and producing exceptional weather variations.

The insurance company Munich Re said in the first six months of the year there were 98 natural disasters in the US, about double the average of the 1990s.

"The increasing impacts of natural disasters, as seen this year, are a stark reminder of the lives and livelihoods at risk. Severe weather represents a very real threat to public safety," said Jack Hayes, director of Noaa's National Weather Service.

But the US is not alone. 2011 has seen the deepest drought in 60 years in the Horn of Africa which has contributed to a famine in Somalia and 10 million people affected in Kenya, Djibouti, Ethiopia and Uganda. Southern Africa, however, experienced unusually heavy rainfall.

Latin America has suffered a series of disasters. More than 500 people died in some of Brazil's worst rainstorms and mudslides in January, and Columbia faced what it called its worst-ever natural disaster when months of rain and floods devastated the north of the country. Meanwhile Mexico and much of central America experienced one of their deepest droughts in many years.

Korea, the Philippines, parts of China have been racked with some of the worst storms in a century, with flash floods and landslides triggered by torrential rain .

2011 has also seen a series of major non-weather-related natural disasters. The worst, by some way, was the Japanese tsunami which killed at least 12,000 people and devastated the country. However, 6.2 or above earthquakes have hit New Zealand, the Philippines, Japan, the Fox Islands, Papua New Guinea, Mexico, Indonesia, Fiji, Thailand, Burma, Vanuatu, Argentina, Chile and Iran in the first six months of 2011. Smaller ones have hit Pakistan, Tajikistan, Tonga, and the Solomon Islands.

In addition the Arctic ice melt this year hit a record in July and is expected to the second or third greatest ever recorded, says the US national snow and ice data centre.

Weather Disasters Keep Costing U.S. Billions This Year
Mary Wisniewski PlanetArk 9 Sep 11;

Blizzards. Tornadoes. Floods. Record heat and drought, followed by wildfires.

The first eight months of 2011 have brought strange and destructive weather to the United States.

From the blizzard that dumped almost two feet of snow on Chicago, to killer tornadoes and heat waves in the south, to record flooding, to wildfires that have burned more than 1,000 homes in Texas in the last few days, Mother Nature has been in a vile and costly mood.

Climate experts point to global warming, meteorologists cite the influence of the La Nina weather phenomenon or natural variability and, in the case of tornadoes hitting populated areas, many simply call the death and destruction bad luck.

But given the variety and violence of both short-term weather events and longer-term effects like a Southwestern drought that has lasted years, more scientists say climate itself seems to be shifting and weather extremes will become more common.

"A warmer atmosphere has more energy to power storms. We've loaded the dice," said Jeff Masters, co-founder and director of meteorology for Weather Underground, Inc, speaking on Wednesday at a news conference on climate. "Years like 2011 may become the new normal in the United States in coming decades."

The year has been expensive, in terms of crops, property and lives lost. The National Oceanic and Atmospheric Administration has kept track of the cost of weather disasters since 1980, and 2011 has seen 10 separate natural disasters with economic losses of $1 billion or more, according to Chris Vaccaro, spokesman for the National Weather Service.

The previous record was nine, set in 2008. The costs go ever higher, with the nine 2011 disasters even before Hurricane Irene two weeks ago costing $35 billion, Vaccaro said.

Other years have been more expensive overall due to single events, such as Hurricane Katrina in 2005. But 2011 has already moved into the top 25 percent of the costliest years, and the hurricane season isn't half over, Vaccaro said.

The Federal Emergency Management Agency (FEMA) says it will need $5.2 billion in known disaster relief for the year that starts October 1. But that doesn't include Hurricane Irene, which caused devastating flooding in Vermont and New Jersey, and is expected to cost at least $1.5 billion in relief, FEMA says.

FIRE AND RAIN

The year began with what was called "Snowmageddon" -- heavy snows in multiple states, including the south.

Kansas got up to 40 inches in some areas in a month -- the same as a typical total for the whole winter. New York had its snowiest January on record.

Snow melt, combined with a wet spring, caused flooding on the Mississippi, Ohio, Souris and Missouri Rivers.

On the Mississippi, records set in the historic floods of 1927 and 1937 were challenged and exceeded along the nation's largest main river artery, resulting in evacuations and millions of acres of flooded farmland.

In the Missouri River valley, flow rates broke previous records, damaging levees and highways.

The year has also been the 4th deadliest tornado year in U.S. history with 546 deaths, according to the NWS.

The May 22 tornado that hit Joplin, Missouri, took 160 lives, making it the deadliest single tornado since 1947.

This summer, the country also baked under days of 100-plus degree heat, with records smashed in northern locations like Newark, New Jersey, which saw a high of 108 degrees.

Texas saw what looks to be its hottest summer, making that vast state into a tinderbox. Wildfires have scorched more than 3.6 million acres since November, fed by a drought that has caused more than $5 billion in damage to the state's farm industry.

In Oklahoma, the average statewide temperature of 86.8 degrees from June to August 31 broke the 85.2 degree mark set in 1934, according to Gary McManus, associate state climatologist. The heat killed 21 people in Oklahoma alone.

Finally, the beginning of hurricane season caused flooding in the aftermaths of Irene and Tropical Storm Lee.

The country is already on pace to break the all-time record for the number of tropical storms strong enough to merit names, Masters said.

NEW EXTREMES

Many years have extreme weather events. Older Americans may recall the "Dust Bowl" of the 1930s, or the bitter Midwest winters of the late 1970s.

Judith Curry, a climate scientist at Georgia Tech, noted in a blog post this week that active hurricane seasons, heavy snowfalls, and floods and severe drought in Texas are reminiscent of the 1950s.

"Natural variability is a plausible explanation for variations in extreme frequency and also clustering of events," Curry said.

While most climate scientists agree that human actions are causing global warming and climate change, not everyone does.

Republican presidential front-runner Rick Perry said last month he does not believe in man-made global warming, calling it a scientific theory that had not been proven. Other political conservatives have questioned evidence of man-made climate change and government plans that could slow it.

Katharine Hayhoe, an atmospheric scientist at Texas Tech University, said policy is not black and white, and there has to be debate over policies to address climate change.

But policy opinions are one thing and scientific facts another, she said, adding that she is troubled to see more of the general public doubting climate change even as more scientific evidence piles up to support it.

"The evidence is what the planet is telling us," Hayhoe said. "These are not political opinions."

ACRES accused of 'cyber attack'

Tan Weizhen Today Online 6 Sep 11;

SINGAPORE - The controversy over the capture and captivity of 25 wild dolphins for Resorts World Sentosa's (RWS) Marine Life Park attraction has taken a new twist, with the resort accusing animal welfare group Animal Concerns Research and Education Society (ACRES) of "cyber harassment" on its Facebook wall.

RWS has claimed that ACRES orchestrated an attack on its Facebook wall constituting of a "barrage of repetitive and abusive messages" - leading to the resort to temporarily suspending postings on its Facebook wall last Saturday evening, while ACRES said the IR had blocked ACRES' followers on the RWS Facebook page, and has been uncommunicative over the issue.

In a statement, RWS said that while it welcomed "constructive dialogue", this incident "contravened the true spirit of building a genuine Facebook community of (RWS) fans ... it also inconvenienced our fans".

RWS, which declared the incident "cyber-harassment", alleged ACRES had called on its followers to carry out the attack between 9am last Saturday and 9pm on Sunday, and that ACRES followers were creating new accounts to do this.

However, Mr Louis Ng, executive director of ACRES, told Today that the purpose of the messages was to put up photo petitions urging the resort to release the dolphins, among other similar messages, and followers had been urged to stay civil. "We are just people who are very passionate about this cause, and have urged them to respond, but they have not replied to a single message," he said.

Wall postings were allowed again yesterday morning. Today understands that the resort only blocked users who were abusive or sent repetitive messages. The controversy began when it emerged that dolphins were caught in the Solomon Islands last January for RWS, and two died in captivity while in a holding area in Malaysia.

Brand online intelligence company Brandtology said that most companies start an online fan page thinking that it is only for their fans. "But it is not something they can control once they open themselves to the world. Such blocking will only draw more negative attention," CEO Eddie Chau said. He said that Asian companies tend to be less receptive in managing stakeholders online compared to American or European companies, due to cultural differences. Tan Weizhen

Smuggling of rhino parts goes online

Channel NewsAsia 5 Sep 11;

SINGAPORE: Rhinoceroses are a protected species, and it is illegal to import their horns here. However, some traders allegedly get round the law by taking the transactions online.

In a correspondence via email, a Channel NewsAsia reporter contacted a seller, allegedly based in Singapore, who claimed to be able to ship the horns over in two days.

This, the seller said, could be done via an international mailing service, disguising them as art pieces.

The demand for horns exists, as some believe they can treat cancer.

But practitioners of traditional chinese medicine said there is no scientific evidence to prove this.

The Agri-Food & Veterinary Authority said it has not seized any illegally-smuggled horns since 1995.

But a local animal welfare group said the illegal acts are still going on.

Mr Louis Ng, executive director at the Animal Concerns Research & Education Society said: "Sometimes they are smuggled in powder form, which is the same property as our fingernails, so it's hard to detect with our current measures in place. But what we really need to do now is employ sniffer dogs, that can sniff out rhino horns, bear parts, tiger parts, (and) live animals. That would be a more effective deterrent."

Activists flood RWS site with messages
Straits Times 6 Sep 11;

ANIMAL rights activists have flooded Resorts World Sentosa's (RWS) Facebook page with hundreds of messages calling for it to release its captive dolphins.

The barrage of posts by supporters of a Singapore-based pressure group forced RWS to block some users and disable the page's comment function.

Yesterday, a spokesman called the activists' behaviour 'premeditated cyber harassment'.

He said blocking users was 'never an ideal response', but added: 'We cannot and will not tolerate any misuse of our Facebook page with spam, repetitive or abusive messages.'

The mass messaging session was carried out last Saturday and Sunday by supporters of Animal Concerns Research and Education Society.

One supporter inundated the page with the same post asking RWS to join her 'dolphins killers team' as it is 'extremely well known for torturing and murdering dolphins'.

Yesterday, the pressure group's executive director, Mr Louis Ng, said comments like these were unfortunate because he had called for the posts to be polite.

But he vowed not to give up the campaign until the dolphins are released. 'We will not budge as long as they have them.'

RWS has 25 of the mammals in captivity in the Philippines and intends to feature them in its planned Marine Life Park. Two other dolphins died of a bacterial infection last October.

Mr Shashi Nathan, director of Inca Law, said that while online campaigns like this may not be good Internet etiquette, there is little RWS can do as its Facebook page is meant to be open for public discussions.

He added that the company 'would have legal remedies if there are messages that are obscene or defamatory, but otherwise, beyond deleting the messages, there is nothing much it can do'.

NUS develops new technology to treat ballast water

Channel NewsAsia 6 Sep 11;

SINGAPORE: A new more compact and environmentally-friendly technology developed locally to disinfect ballast water in ships may soon be used on vessels plying international shipping routes.

The new technology is developed by a team of researchers from the Faculty of Engineering at the National University of Singapore (NUS).

It treats the water using electrolysis and is already approved by the International Maritime Organisation (IMO).

The system uses a patented and cost-effective electrode and a series of supporting devices to treat ballast water over a period of 10 to 12 hours.

An NUS spin-off company has been formed to commercialise the technology in the next few years.

The IMO requires all existing ships to be fitted with such systems by 2016.

The development of the system was funded by the Maritime and Port Authority of Singapore (MPA).

Ballast water is taken on and discharged by ships to maintain their stability while loading and unloading cargo. It is disinfected to prevent aquatic organisms being transferred from one environment to another, which could be harmful to the biodiversity of the local marine ecosystem.
