Massive sandstorm turns Beijing's streets yellow

Tons of sand from deserts in China's interior blew into Beijing Saturday, shrouding China's capital in a yellow-orange haze that authorities warned made the air quality "hazardous."
There were few people out on streets where pedestrians could taste the dust. Many of those who had ventured from their homes were wearing facemasks, and some left footprints in the yellow film that had settled on the city's streets.
Beijing's weather forecasting bureau gave the air quality a rare "5," or hazardous, rating and added that it was "not suitable for morning exercises." Parks and open spaces are usually packed from early in the day with enthusiasts doing martial arts, ballroom dancing and other activities.
The sandstorms underline the environmental degradation investors identify as one of the long-term constraints on growth in China, and concern about its impact has made a less resource-intensive model of growth a priority for Beijing.
The government has spent millions of dollars on projects to rein in the spread of deserts, planting trees and trying to protect what plant cover remains in marginal areas.
But the battle is being fought against a backdrop of rising average temperatures and increasing pressure on water resources after three decades of booming growth.
The sandstorm hit Beijing around midnight, carrying huge amounts of dust and heading south east, the official Xinhua news agency said. In northern Changping district, the wind reached speeds of up to 100 km per hour (60 mph).
The swirling clouds of dust and sand had blanketed the interior provinces of Qinghai and Gansu, and western Xinjiang region, before sweeping over the capital, Xinhua said.

Bold new plan for confronting climate change

Weather bureau backs climate change verdict

The leading research bodies say the evidence is irrefutable: climate change is real and the link with human activity is beyond doubt.
Universities have also joined the fray, saying it is time to stand up for Australian science and research.
"We've had some serious tabloid junking of ... science and research in our community," Professor Peter Coaldrake, the chairman of Universities Australia, said.
"If the two bodies together come out and make a statement of this sort, then we in the community have to acknowledge that."
The weather bureau's director, Greg Ayers, says a century's worth of climate records show definitively that weather patterns are shifting and the planet has already been warming.
There are simply more extremely hot days, and fewer cold and wet ones.
"When we look back over the last 50 years or so and look at the succeeding decade as we roll forward, what we see ... is a trend of increasing temperatures from decade to decade," Dr Ayers said.
"We also see shifts in patterns of rainfall with the drying in the east and the south and the west of the continent.
"There is an increase in temperature in the surface oceans around Australia as well that goes hand in hand with the ... surface temperature increases over the continent, and there's also ... a rise in sea level."

Open to public


Dr Ayers says the bureau's data is available for the public to scrutinise.
"For the Australian region, we have around 100 climate reference stations, as we call them, where we pay a great deal of attention to doing the best possible measurements," he said.
"I'm very pleased to be able to say that our climate record in Australia is as good or better than any comparable record anywhere in the world."
But Mr Ayers says the weather bureau is primarily responsible for measuring the climate, whereas it is the CSIRO that handles climate projections.
The CSIRO says on its current path, the planet is heading for a rise in temperature of a further 2 degrees Celsius this century.
The head of the organisation, Dr Megan Clark, says the evidence is clear.
"Hotter days, more extreme heat and less rainfall are the snapshot of Australia's climate now, not the forecast," she said.
"In Australia, we're seeing that all of Australia is warming, in every state, over every season."
Dr Clark says it is clear the climate is being affected by the carbon emissions caused by human activity.
"Our scientists and those around the world are now about 90 per cent sure that these things are happening at the same time and are linked," she said.

Meltdown of Public Opinon on Climate Change

RECENT events are now resulting in more people questioning the validity of the science behind climate change. Could this be the beginning of a meltdown in public opinion on global warming?




The recent period of freezing temperatures and the failure of the Copenhagen climate summit to agree legally binding greenhouse gas targets provided the backdrop for two events that have threatened the creditability of climate change science.



The “Climategate” fiasco saw the contents of emails stolen from the University of East Anglia’s Climatic Research Unit leading to accusations that a number of researchers had manipulated data.



Meanwhile, the Intergovernmental Panel on Climate Change (IPCC), the leading body for the assessment of the scientific evidence of climate change, admitted it had got it wrong on predicting Himalayan glaciers could disappear by 2035.



Taken all together, it is not surprising that the general public is beginning to question whether climate change is really happening. A recent BBC Poll suggests that scepticism about climate change is on the rise. Of the 1,001 adults polled, 25 per cent did not think global warming was happening.



This is a 10 per cent increase on a similar poll that was conducted last year. Those who said climate change was real had fallen from 83 to 75 per cent. Only 26 per cent believed that climate change was happening and was largely the result of human activities.



Climate change is unlike any other environmental issue. For some, it is seen as a new religion with those sceptical of the evidence labelled “deniers” as if they were questioning the existence of a divine being. Unless you live on a small island state such as Tuvalu, near Fiji, which is slowly sinking due to the rising sea level, it is easy to think climate change is a myth.



There is also public confusion over the difference between weather – atmospheric conditions over hours or days – and climate – changes in the atmosphere over years. This has led some people to think that the recent heavy snowfall and sub-zero temperatures are sufficient evidence that global warming is not real.



How climate change is communicated plays a powerful role in influencing public attitudes and determining whether people are willing to reduce their carbon footprint. The alarmist language used by the media to describe the potential impact of climate change has been referred to as “climate porn” – offering a thrilling spectacle but ultimately distancing the public from the problem. The use of apocalyptic media images of receding glaciers, scorched land, flooded metropolises and polar bears grappling for survival all foster public apathy.





It is no wonder the public feels disempowered. The issue is portrayed as being so big and multifaceted that it seems unreal and more like science fiction rather than science fact.



Climate sceptics are quick to claim that Climategate and the “Glaciergate” are evidence of “dodgy” climate science. While a few points in the IPCC report may be incorrect, this does not invalidate the last four assessments of the basic science of climate change. There is overwhelming evidence to suggest that global warming is due to human activity.



The reality is that climate science is still developing as new evidence comes to light. We are still trying to understand the complexity of the global climate system and the effect and speed of different feedback mechanisms.



For example, a scientific survey of Siberian tundra coastlines has reported methane levels are roughly 100 times above normal. Methane is a greenhouse gas 20 times more powerful than carbon dioxide.



More than 10 times the annual global greenhouse emissions are thought to be trapped in tundra across the world. As the tundra thaws will it become a “Methane Bomb”?



Health damaging particles in polluting gases emitted by industry, traffic and domestic heating have a “cooling” effect on the climate. In reducing local air pollution are we lowering this cooling effect and inadvertently accelerating global warming?





Many questions such as these require further scientific investigation.



It is too easy to dismiss the whole climate change issue as mass hysteria. Prevention is always much better than cure. It is right that we take action now to reduce greenhouse gas emissions, adapt to predicted climate change and move to a low carbon economy.



We need to become more efficient in our energy use and develop renewable energy sources. After all, whether climate change happens or not, we still have to face up to the fact of dwindling oil reserves and our over-consumption of natural resources.



Whatever doubt we may have about climate science, or whether climate change is really happening, a fundamental question remains – are we willing to gamble with our children’s future on this planet?

'Green' plastics may be worse for environment

A type of degradable plastic bag that was supposed to be better for the environment may not be completely biodegradable, a Government-commissioned study has found. The bag is made with metal salts that are supposed to accelerate degradation, but scientists found the material was not fully biodegradable and might contaminate the way plastics are recycled.






Hundreds of millions of plastic bags and packaging items have been produced by the process, and they are widely used by some of the leading British retailers, including Waitrose, Ocado, JD Sports, Accessorize, River Island and Tesco.



Plastics with the additives are meant to break down quickly and fully in the presence of light and air by a process called oxidative degradation. But the term biodegradable is "virtually meaningless" said the Loughborough University scientists who ran the study. "The bags cannot be composted and there are concerns about the effects of the plastic in recycling facilities," said the scientists, who added that the best way of disposal was incineration or landfill.



UN Appeal for Haitian Quake Relief Only Half Funded

Two months after the ruinous January 12 earthquake in Haiti, the United Nations' $1.44 billion revised humanitarian appeal for the country is only 49 percent funded, UN officials said today.




The UN Office for the Coordination of Humanitarian Affairs, OCHA, says humanitarian work is picking up speed, but emergency shelter and sanitation are still urgently needed ahead of the rainy season. Steady rains could come as soon as the end of March, and hurricane season starts in June.



More than 212,000 people died as a result of the 7.0-magnitude quake and nearly 300,000 others were injured. The number of displaced people amounts to about 1.2 million, according to Haitian government figures.

OCHA reports that more than 4.3 million people have received food assistance, 1.2 million people are receiving daily water distributions, and more than 300,000 children and adults have been vaccinated against a range of infectious diseases, including measles, rubella, diphtheria, tetanus and whooping cough.



Emergency shelter materials have been distributed to more than 650,000 people, about 56 percent of those left homeless by the quake, which claimed the lives of more than a quarter of a million people.



UN Secretary-General Ban Ki-moon will make a one-day visit to Haiti on Sunday, his second to the Caribbean country since the earthquake, his spokesperson Martin Nesirky told reporters at UN headquarters in New York today.



While in the capital, Port-au-Prince, Ban will meet with President Rene Preval and Prime Minister Jean-Max Bellerive, as well as with the leadership of the UN Stabilization Mission in Haiti and UN agencies working on the ground.

The Secretary-General will visit a camp housing some of the people displaced by the earthquake.



Preparations are now starting on two sites identified by the Haitian government for the relocation of internally displaced persons from high-risk settlement sites. The first site for relocation will have its official inauguration tomorrow.



The earthquake disaster is compounded by the lack of trees in Haiti, which has one of the worst rates of deforestation in the world.



Only two percent of Haiti's original forests remain and Haitian deforestion makes it impossible to source timber for transitional shelters from within the island nation. Timber to create transitional shelter for up to 500,000 people for two years will have to be imported with support from the international community, UN officials say.



The UN Food and Agriculture Organization is asking people to help children in Haiti by donating a fruit tree that they can plant in school yards across the country.



FAO Director-General Jacques Diouf will launch the Fruit Trees for Haiti initiative at a symbolic tree-planting at a school in the town of Croix des Bouquets, outside of Port-au-Prince. While untouched by the earthquake, the school now is hosting tens of thousands of refugees from the capital.

Diouf is on a three day mission to Haiti to raise awareness about the need for international support to agriculture in Haiti.



He says a $5 donation to the initiative buys an avocado or mango tree for a Haitian school garden, and covers fertilizer and other inputs as well as educational material about the value of trees. For instance, buildings surrounded by trees are better protected from the flooding that can occur in the Haitian rainy season.



The FAO and the nonprofit aid agency CARE have issued a joint alert over a national food crisis in Haiti.



Rapid assessments undertaken by FAO and its partners have shown that "host families" caring for displaced people are spending their meager savings to feed new arrivals and consuming food stocks. In many cases, they are resorting to eating the seeds they have stored for the next season and eating or selling their livestock.



The main planting season, which accounts for over 60 percent of annual production, has now begun, but Jean-Dominique Bodard, CARE's emergency food security specialist, warns, "If the host families have no means to buy seeds or other ways to obtain quality seeds, this will be a disaster for them."



"And there is another aspect to this vicious circle: due to lack of cash, many host farmers will not be able to hire day laborers for the planting," he said. "As an effect, the laborers will not earn money to feed their families and the planting will not be carried out to the extent it could be if the workforce were available."



FAO has kick-started a small cash-for-work program cleaning out irrigation canals in Leogane and CARE will work to scale it up in the coming days from 600 to 4,000 people.

A larger cash-for-work program is being run by the UN Development Programme. As of March 5, more than 70,000 Haitians were employed under this program, and UNDP has set the goal of reaching more than 400,000 people by December 2010, indirectly benefiting two million Haitians. Each worker is paid 180 gourdes, or about US$4.5, for six hours of labor.



The work includes removing building rubble from the streets, crushing and sorting reusable material, disposal of debris, and restoring essential public facilities to lay the foundations for mid-term recovery and development. Haitians are also clearing sites for safe re-settlement, repairing surface water drainage and improving road access to and through affected areas.



On sanitation, 3,673 latrines of the required 13,000 latrines have been installed, but there are space problems due to millions of tons of debris in the streets, according to the UN Children's Fund, UNICEF, which is leading the sanitation effort.



Haiti's traditional system of separating trash by hand has raised concerns about contamination from healthcare waste given the burst in medical activity.



"It is estimated that the volume of healthcare waste had tripled," Andrew Morton, UNEP programme manager in Haiti, told a news conference in Geneva. UNEP has brought in a large number of containers for segregation of waste, and purchased additional fuel for trash incineration.

The World Health Organization has warned about the increased risk of water-borne diseases when the rainy season begins. Malaria cases have already started to increase, WHO spokesperson Paul Garwood told reporters at the Geneva briefing.



Aid officials are also worried about an expected increase in malnourished children. An estimated 500,000 children under five years and some 200,000 women who are pregnant or with infants have been affected by the earthquake, according to UNICEF.



The agency is working with WHO and other partners to send mobile psychosocial teams to speak with families in settlements throughout the region. The therapeutic activities include the traditional Haitian concept of "lakou," a place where families gather and chat.



In addition to counselling, aid officials hope that going to school will help normalize the lives of some children. Some 1,400 tents are being set up for some 200,000 children to start attending school in shifts starting on April 1.



"The international response has been very generous, including from a number of developing countries," said Jordan Ryan, director of UNDP's Bureau for Crisis Prevention and Recovery. "But Haiti needs continued donor support to build strong democratic institutions, put in place effective disaster preparedness measures and reduce extreme poverty. Now is the time for even more support for the people of Haiti."
