Bacteria transform landfill methane

Biofilters can convert around a fifth of the wasted methane from old landfill sites into less harmful gases says new research. Methane has a much greater impact on global warming per amount of gas than carbon dioxide and landfills account for 12% of global anthropogenic methane emissions.

Fish feeding on plastic in ocean's 'Garbage Patch'

Fish feeding on plastic in ocean's 'Garbage Patch'

A team of American researchers have travelled to the Pacific Ocean's dirtiest waters to find that nine per cent of the fish there are eating our waste in the form of tiny specs of plastic. The garbage patch is known more correctly as North Pacific Subtropical Gyre, 1,000 miles off the Californian coast, and it was discovered that fish are eating 12,000 to 24,000 tons of plastic each year.

New project launches to help improve scientists ability to track air pollutants via satellite. Low flying planes will be seen across Maryland in a programme called DISCOVER-AQ which is designed to improve the ability of satellites to measure the ground level air quality on earth from space.

Plug Ghana's poor into gas network, and halt smoke-related illnesses

Plug Ghana's poor into gas network, and halt smoke-related illnesses

Posted Mon, 20 Jun 2011 19:00:00 GMT by Martin Leggett

A new study on the use of fuels in Ghana's capital shows that the poor are locked out of clean fuel use - so suffering from increased pollution from tiny particles in cooking smoke. With the country developing its natural gas potential, the authors - publishing in Proceedings of the National Academy of Sciences - argue that both the health of the poorest, and the country's forests, will benefit from the slashing of charcoal use, in favor of gas.

Cities Change Wind Patterns, Raising Pollution

Cities Change Wind Patterns, Raising Pollution

Warm nighttime temperatures change wind patterns, trapping pollutants in cities. Amongst U.S. cities, Houston has some of the highest levels of pollutants like ozone at the ground level. In Houston, urban development inhibits winds from sweeping pollutants out to the ocean at night.

Algae could be used to clean polluted waters and scientists believe there could even be money to be made from the process' byproducts. The algae - described as turf scrubbers - are used in areas the size of fields and can 'clean' water contaminated with nitrogen and phosphorus.

Scientists cast doubt on claims microbes consumed much of the Deepwater Horizon methane plume

Scientists cast doubt on claims microbes consumed much of the Deepwater Horizon methane plume

Doubts raised by scientists that microbes consumed much of the Deepwater Horizon methane plume. All organic life on earth utilises carbon as a nutrient. Some bacteria are able to ingest methane, the simplest hydrocarbon, to satisfy this need, in part at least.

Local communities empowered to take on ocean's acidic hotspots

Acidic hotspots in coastal waters can destroy local livelihoods, as well as damage marine ecosystems. But a Policy Forum paper in tomorrow's Science claims that US communities have the power in their own hands to practically deal with such hotspots - without waiting for foot-dragging state and federal authorities to lumber into action.

A study has found that the prevalence of fertiliser-derived nitrogen as a pollution source in the Caribbean is declining. This is attributed to the adoption of more environmentally sensitive agricultural practices in recent years which have changed fertiliser application practices.

The announcement of 3 new advanced sensors for tracking oceanic acidity levels, made yesterday by the University of Alaska Fairbanks, will help scientists monitoring this worrying knock-on from rising CO2 levels. If CO2 levels keep pushing the ocean's acidity up, many organisms relying on limy shells will be threatened.

Two-thirds of Michigan students are stuck in schools in the most polluted parts of the state, says a new study in Health Affairs. That's leading to bad effects on student's health and performance, and points to the need for stronger environmental assessment during planning for school sites, say the authors.

Developed world countries, such as the US and the EU nations have been happy to claim the climate-change 'high ground', as their emissions stabilized over this last decade. But a new report confirms that this is an accounting illusion - with more emissions being 'exported' to developing countries, who increasingly make the goods consumed by the richer nations.

Latest figures show Australia's carbon emissions are on the rise again. The latest data to be released by Australia's Department of Climate Change and Energy Efficiency shows that the emissions of carbon for the year of 2010 are 0.5 percent higher than the emissions from 2009.

Gold fever is driving Amazon loss and mercury pollution in Peru

Soaring gold prices are causing tumbling rainforests in Peru's Amazonian lowlands says a new study published today in the open-access journal PloS ONE. A leap in the area being felled for small-scale gold mining has bought with it increased emissions of mercury, toxic both to impoverished miners and to the wider environment. Controlling mercury may be the key.

Charging electric cars at night eases ozone haze

Ozone levels could be cut if the charging of electric cars is timed just right - so says a paper in Environmental Research Letters published online tomorrow. The authors looked at the effect on pollution from power-plants - which still feed much of the electricity for electric cars - and found night was best for reducing ozone hazes. This reinforces to the need to plan electricity tariffs to encourage the best charging behavior from the growing electric car-using population.

Mercury burden hangs heavy round the neck of the albatross

That omen of goodwill or ill, the albatross, is itself suffering from misfortune, as a result of man's continued emitting of toxic mercury compounds. These have been shown, in new research published in Proceedings of the National Academy of Sciences, to be accumulating in higher amounts in top predators such as albatrosses. This could threaten their survival, by reducing their reproductive success rates, says the analysis of bird feathers collected over the last century.
