India 2012, an e-waste bin

What a dump, and it is growing by the hour. Almost 40 per cent of the municipal and plastic waste generated in India is not collected, and half of the organic waste goes untreated. And then there is the growing problem of electronic waste.
By 2012, India will generate the most e-waste in the world, second only to China. Most cities do not have adequate infrastructure to manage the growing household and plastic rubbish, even though there are technologies available for treatment and reuse.
"There are only 110 facilities in the country for treating hardly 50 per cent of the organic waste generated," says the environment ministry's report on Road Map on Management of Waste in India A committee of the ministry has sought a law for waste-management with punitive action against defaulters.
The report call for higher penalty for those failing to properly dispose of municipal garbage. "Unless the city administrations get serious about waste management, the problem could become a major health risk," an official, who didn't wish to be identified, said. But, it's the economic growth that poses the biggest challenge - managing e-waste, which can be a discarded refrigerator or end-of-life cellphone or a laptop.
By 2012, India will generate over 800,000 million tonne (mt) of e-waste every year. At present, Mumbai tops the e-waste chart followed by Delhi. Western countries are adding to this mound. The estimate is not known as the ministry believes much of the e-waste is brought in illegally. NGOs such as Toxic Link have raised health concern over US and Europe dumping e-waste in India.
Even though disposing e-waste is defined under Hazardous Waste Management Rules in 2008, most cities don't have a system to collect and dispose of discarded gadgets. "Producers should be bound to take back their products after the life of the product is over and to get it recycled/disposed in. without health risks," says the report released on Thursday.
Poor management of the industry-generated hazardous waste is another worry. Annually 6.2 mt of the waste is generated and 2.1 mt goes untreated. The report talks of 36,000 hazardous waste industries, which include those manufacturing chemicals and plastic. Indiscriminate disposal has left many places environmentally degraded, says the report.

China and India: Neighbors Need to Collaborate for Sake of Global Environment

With large and growing economies and populations, China and India will strongly influence the quality of the global environment for years to come. While their political relationship is strained, it's critical the two countries work together to slow global warming, deforestation, water shortages and other environmental issues, says a Michigan State University scientist  and colleauges."China and India are the two largest countries in terms of population," said Jianguo "Jack" Liu, MSU University Distinguished Professor of fisheries and wildlife who holds the Rachel Carson Chair in Sustainability. Liu is internationally known for his work on environmental sustainability and coupled human and natural systems. "Even while the rest of the world is in a recession, the economies of China and India are growing and the countries' consumption of raw materials is increasing. Cooperation between the two is vital to mitigating negative environmental impacts." In "China, India and the Environment," published in the March 19 issue of the journal Science, Liu and co-authors advocate using scientific collaboration as a bridge to help break down political barriers between the two nations -- ultimately benefiting the larger global society. All the authors have strong research programs in one or both of the countries.
"We all have a huge interest in a sustainable world and the way we're managing it now, it simply isn't sustainable," said Peter Raven, co-author and president of the Missouri Botanical Garden. Raven also is a foreign member of both the Chinese and Indian academies of science. "The problems get worse every year; biodiversity loss and climate change have clear global significance. Our thesis is the two countries share so much adjacent territory that the environmental benefits should be obvious and, informed by scientific analysis, should provide a bridge between them."
According to Liu, water availability could be an increasingly challenging issue facing the two countries and one that will require careful cooperation. Many rivers flow through both China and India -- if one country builds too many dams on its side to generate hydroelectric power, it will likely cause water shortages downstream in the other country.
"Water is a huge issue," said Liu. "It's being discussed extensively. We need to make people aware of the benefits of cooperation. It's more than just China and India that will be affected if these two countries don't work together. The environmental impacts will be felt around the world, including in the United States."
"One thing we have learned from the recession is that without sustainability there cannot be unlimited growth," added Kamaljit Bawa, University of Massachusetts-Boston distinguished professor of biology and president of the Ashoka Trust for Research in Ecology and the Environment in Bangalor, India. "The two countries are not facing recession and it is time for them to exercise environmental stewardship. Future economic growth is contingent upon this stewardship."
In addition to Liu, Raven and Bawa, other paper authors are Lian Pin Koh, of the Institute of Terrestrial Ecosystems in Zurich, Switzerland; Tien Ming Lee, of the University of California-San Diego and Yale University; P.S. Ramakrishnan, of Jawaharlal Nehru University, in Delhi, India; and Douglas Yu and Ya-ping Zhang, of the Kunming Institute of Zoology, in Yunnan, China.
Liu's research is supported by the Michigan Agricultural Experiment Station, the National Science Foundation and NASA. He serves as principal investigator of the International Network of Research on Coupled Human and Natural Systems, funded by the NSF and coordinated by the MSU Center for Systems Integration and Sustainability, which Liu also directs.

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?
