Scientists are reporting discovery of an improved way to remove carbon dioxide — the major greenhouse gas that contributes to global warming — from smokestacks and other sources, including the atmosphere. Their report on the process, which achieves some of the highest carbon dioxide removal capacity ever reported for real-world conditions where the air contains moisture, appears in the Journal of the American Chemical Society.

Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues explain that controlling emissions of carbon dioxide (CO₂) is one of the biggest challenges facing humanity in the 21st century. They point out that existing methods for removing carbon dioxide from smokestacks and other sources, including the atmosphere, are energy intensive, don’t work well and have other drawbacks.

In an effort to overcome such obstacles, the group turned to solid materials based on polyethylenimine, a readily available and…

The Jian River in Luoyang, China had become a “river of blood”…Locals were subject to the water’s eerie, blood-like color for several days before government officials tracked the source of the color not to a Moses-like End Times but to two small chemical plants.

Although media outlets were alerted to the spill by citizens’ panicked calls, others who live neat the water are unsurprised, saying the water changes color often due to the various pollutants dumped into or along the river on a weekly basis. Some Chinese locals report that the river has turned dark green in the past.

Congested cities are fast becoming test tubes for scientists studying the impact of traffic fumes on the brain.

As roadways choke on traffic, researchers suspect that the tailpipe exhaust from cars and trucks—especially tiny carbon particles already implicated in heart disease, cancer and respiratory ailments—may also injure brain cells and synapses key to learning and memory.

New public-health studies and laboratory experiments suggest that, at every stage of life, traffic fumes exact a measurable toll on mental capacity, intelligence and emotional stability…

Ordinary Beijingers could take some comfort in the knowledge that the soupy air they breathe on especially polluted days also finds its way into the lungs of the privileged and pampered. Such assumptions, it seems, are not entirely accurate.

As it turns out, the homes and offices of many top leaders are filtered by high-end devices, at least according to a Chinese company, the Broad Group, which has been promoting its air-purifying machines in advertisements that highlight their ubiquity in places where many officials work and live.

The company’s vice president, Zhang Zhong, said…

Where are the criminal prosecutions of the major corporations responsible for the oil spill in the Gulf of Mexico? Still nowhere to be found. Where are the prosecutors? Where is the Environmental Protection Agency (EPA)? Not prosecuting major polluters.

Instead, what are they doing? Cracking down on whistleblowers. And those who support whistleblowers. While the corporate crooks are running free.

Next time you think of this disparity of justice, remember these two words: Jon Grand.

For more than twenty years, Grand was a senior administrator at the EPA in Chicago. Never had a run in with the law. Then, he made the mistake of supporting an EPA whistleblower.

In 2000, Grand was talking on the phone with colleagues in Washington. And the EPA people in Washington were making disparaging remarks about Marsha Coleman-Adebayo – a young African-American EPA staffer who was suing the EPA and its administrator – Carol Browner –…

Pesticides and pollutants are related to a 450 percent increase in the risk of spina bifida and anencephaly in rural China, according to scientists at The University of Texas at Austin and Peking University.Two of the pesticides found in high concentrations in the placentas of affected newborns and stillborn fetuses were endosulfan and lindane. Endosulfan is only now being phased out in the United States for treatment of cotton, potatoes, tomatoes and apples. Lindane was only recently banned in the United States for treatment of barley, corn, oats, rye, sorghum and wheat seeds.

Strong associations were also found between spina bifida and anencephaly and high concentrations of polycyclic aromatic hydrocarbons (PAHs), which are byproducts of burning fossil fuels such as oil and coal. Spina bifida is a defect in which the backbone and spinal canal do not close…

Hundreds of villagers in eastern China have held three days of protests at a solar panel plant over pollution fears. Around 500 people started gathering at Zhejiang Jinko Solar company in Haining city, Zhejiang province, on Thursday. Some of protesters stormed the factory, overturning several company cars and destroying offices, officials said. Residents in the nearby village of Hongxiao said they became concerned after the deaths of a large number of river fish.

One 64-year-old villager told the Associated Press that the factory — located close to a school and kindergarten – discharges waste into the river and spews dense smoke out of a dozen chimneys. “The villagers…

Scientists in the US have warned NASA that the amount of so-called space junk orbiting Earth is at tipping point. A report by the National Research Council says the debris could cause fatal leaks in spaceships or destroy valuable satellites.

It calls for international regulations to limit the junk and more research into the possible use of launching large magnetic nets or giant umbrellas. The debris includes clouds of minuscule fragments, old boosters and satellites.

Some computer models show the amount of orbital rubbish “has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures,” the research council said in a statement on Thursday.

Goi is now a dead village. The two fish ponds, bakery and chicken farm that used to be the pride and joy of its chief deacon, Barrisa Tete Dooh, lie abandoned, covered in a thick black layer. The village’s fishing creek is contaminated; the school has been looted; the mangrove forests are coated in bitumen and everyone has left, refugees from a place blighted by the exploitation of the region’s most valuable asset: crude oil.

A long-awaited and comprehensive UN study exposed the full horror of the pollution that the production of oil has brought to Ogoniland over the last 50 years.

The UN report showed that oil companies and the Nigerian government had not just failed to meet their own standards, but that the process of investigation, reporting and clean-up was deeply flawed in favour of the firms…

The speed and rate of degeneration of the oceans is far faster than anyone has predicted; many of the negative impacts identified are greater than the worst predictions; the first steps to globally significant extinction may have already begun.

The world’s oceans are faced with an unprecedented loss of species comparable to the great mass extinctions of prehistory, a major report suggests today.

The seas are degenerating far faster than anyone has predicted, the report says, because of the cumulative impact of a number of severe individual stresses, ranging from climate warming and sea-water acidification, to widespread chemical pollution and gross overfishing.

The coming together of these factors is now threatening the marine environment with a catastrophe “unprecedented in human history”, according to the report, from a panel of leading…

The solution is cheap since the sources of graphite could include the waste produced by graphite mining companies that still contains a significant amount of graphite. And the researchers believe that it is possible to modify the graphite oxide to pick out particular pollutants and therefore tailor the super sand to specific areas that might be having trouble with certain water-borne diseases or pollutants.

Australia is considering awarding carbon credits for killing feral camels as a way to tackle climate change.

The suggestion is included in Canberra’s “Carbon Farming Initiative”, a consultation paper by the Department of Climate Change and Energy Efficiency, seen Thursday.

Adelaide-based Northwest Carbon, a commercial company, proposed culling some 1.2 million wild camels that roam the Outback, the legacy of herds introduced to help early settlers in the 19th century.

Considered a pest due to the damage they do to vegetation, a camel produces, on average, a methane equivalent to one tonne of carbon dioxide a year, making them collectively one of Australia’s major emitters of greenhouse gases.

In its plan, Northwest said it would shoot them from helicopters or muster them and send them to an abattoir for either human or pet…

Americans are suffering from asthma in record numbers, according to a study released by the Centers for Disease Control and Prevention. Nearly one in 10 children and almost one in 12 Americans of all ages now has asthma, government researchers said.

According to the report, from 2001 to 2009 the prevalence of asthma increased among all demographic groups studied, including men, women, whites, blacks and Hispanics. Black children are most acutely affected: the study found that 17 percent of black children — nearly one in five — had a diagnosis of asthma in 2009, up from 11.4 percent, or about one in nine, in 2001.

While officials at the Centers for Disease Control emphasized that asthma could be controlled if managed effectively, they were at a loss to explain why it had become more widespread even as…

For smokers, the world has always been one big ashtray, with cigarettes flicked away pretty much anywhere. That’s especially true now, since smokers are increasingly forbidden to light up in restaurants, office buildings and even new no-smoking condos. In the great river of litter human beings create each year, so tiny a thing as a cigarette butt hardly seems to amount to much. But with the world’s smokers burning through a breathtaking 5.6 trillion cigarettes per year — 4.5 trillion of which are simply tossed away outside after they’re smoked — little things add up fast. That, as it turns out, can be especially dangerous for one type of nonhuman critter: fish.

About a third of all of the trash found on U.S. shorelines consists of cigarette butts. There’s no…

Thousands of Humboldt squid died off the coast of Oregon in 2004 and hundreds again in 2008. The culprit was originally considered a shift in deep-sea currents, but a new study pinpoints the physical trauma noise pollution can inflict on cephalopods and raises new concerns over the incidents of squid strandings. Dolphins and whales and other marine mammals aren’t the only sea life vulnerable to noise pollution from human activities.

Earlier indications that squid might be susceptible to noise occurred in 2001 and again in 2003, when giant squid washed up along the shore of Asturias, Spain. After struggling to identify the reason, biologists eventually concluded that the deaths were most likely related to the presence of vessels using seismic air guns for geophysical prospecting of the seabed.

A new study, published in the journal Frontiers in Ecology and the Environment, has found that even low intensity noise can leave cephalopods damaged and…

Engineers battling to contain the crisis at Japan’s Fukushima nuclear power plant appeared to have turned an important corner last night after they stopped highly radioactive water from leaking into the ocean from one of the facility’s crippled reactors.

Workers struggling to halt the leaks successfully used a mixture of sawdust, newspaper, concrete and a type of liquid glass to stem the flow of contaminated water near a seaside pit, said the plant’s owner, Tokyo Electric Power Co (Tepco).

Earlier efforts involving cement, an absorbent polymer and rags were unsuccessful in plugging the leak, which was discovered on Saturday, while radiation of more than 7.5 million times the legal limit for seawater was found just off the earthquake-hit plant.

In a sign of Tepco’s desperation, it breached its own regulations on Monday by beginning an intentional discharge of 11,500 tonnes of less contaminated water…

Last week, Nicola wrote about an interactive chart that compared the number of deaths per terawatt-hour that could be attributed to a few major sources of energy. Yesterday, Seth Godin did the world a service by simplifying that rather complicated chart.

This is a “non-exaggerated but simple version” of the original deaths/TWh statistics. Perhaps the most stunning, simple takeaway:

For every person killed by nuclear power generation, 4,000 die due to coal, adjusted for the same amount of power produced.

Godin also mentions this incredibly important point, which cannot be driven home hard enough:

Not included in this chart are deaths due to global political instability involving oil fields, deaths from coastal flooding and deaths due to environmental impacts yet unmeasured, all of which skew it even more if you think about it.

So, actually, it’s even worse. As everyone debates the costs and benefits, the pros and cons, and the feasibility of…

China has overtaken the US for the first time in a league table of investments in low-carbon energy among the G-20, according to a new report by not for profit group the Pew Charitable Trusts published this week.

The report found that despite an overall 6.6 per cent global decline in clean energy investments last year, China invested almost twice as much as the United States in clean energy during 2009.

But the US still leads in energy capacity. It’s interesting for the UK too:

• third in overall clean energy investments
• fourth in five-year clean energy investment growth rate
• fifth in the percentage of total power it receives from clean energy sources ahead of France, China and the US

Bicycling is a great way to burn calories and get fit. But a new kind of bike may improve the health of entire communities in an entirely different way.

Nippon Basic, a start-up based in Japan, has plans to scale up production of a bicycle that purifies water for those living in remote villages or disaster areas. Cycloclean functions just like any other bicycle, except that the addition of a water filtering system allows bikers to crank out drinking water using the same pedaling motion that propels bikers forward. The rotation of the bike chain helps to remove impurities by driving a motor that pumps water through a system of filters, pumps and hoses located near the rear wheel.

But just how much drinking…
