Too little attention is paid to the side effects of emission-limiting measures
With measures aimed at reducing the emission of pollutants such as ammonia, policy makers pay too little attention to the consequences for the emission of other substances. This is revealed in a computer model constructed by Corjan Brink from Wageningen University during his doctoral research. For example, the model shows that reducing the amount... view more...

Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and over the last 200 years its concentration in the... view more... (2000-05-10)
Fish oils reduce greenhouse gas emissions from flatulent cows
The benefits to animals of omega 3 fatty acids in fish oils have been well documented - helping the heart and circulatory system, improving meat quality and reducing methane emissions. view more (2009-03-30)
Putting a green cap on garbage dumps
andfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming issue of International Journal of Environmental... view more...

Methane gas levels begin to increase again
The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers. view more (2008-10-30)
Stressed crops emit more methane than thought
Scientists at the University of Calgary have found that methane emission by plants could be a bigger problem in global warming than previously thought. view more (2009-08-18)
Verification of national methane estimates now possible
New methods for verifying estimated greenhouse gas emissions, developed by scientists at Royal Holloway, University of London, will play a significant role in assessing reductions in methane emissions, important in national compliance with Kyoto protocol targets. David Lowry, Craig Holmes, Nigel Rata and Euan Nisbet of Royal Holloway’s... view more... (2001-04-25)
Explaining the methane mystery
Scientists have explained why atmospheric levels of the greenhouse gas methane have stabilised in recent years, but warn that increases could resume in the near future. view more (2006-09-28)
New material could make gases more transportable
Chemists at the University of Liverpool have developed a way of converting methane gas into a powder form in order to make it more transportable. view more (2008-11-21)
Landfill Cover Soil Methane Oxidation Underestimated
Landfilled waste decomposes in the absence of oxygen and results in the production of methane. Landfills are classified as the second-largest human-made source of CH4 in the U.S. Additionally, landfill gas contains numerous non-methane hydrocarbons that are either volatilized directly from waste materials or produced through biochemical reactions... view more...

Researchers find way to cut cattle methane, threat to environment, by 25 percent
Beef farmers can breathe easier thanks to University of Alberta researchers who have developed a formula to reduce methane gas in cattle. view more (2009-05-08)
REDUCTION OF RICEFIELD METHANE EMISSION
Methane (CH4) is considered to be the third most important gas, after carbon dioxide (CO2) and freons, in its contribution to the greenhouse effect and hence to global warming. Cores taken from the ice cap have shown that its concentration in the atmosphere has tripled in 100 years. This figure would explain about 20% of the rise in temperature... view more... (1999-07-07)
A new link between nickel, methane gas and the evolution of complex life forms on Earth
A University of Alberta researcher is lead author on a paper that reaches back billions of years to establish a new link between nickel, methane gas and the evolution of complex life forms on Earth. view more (2009-04-09)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
Study reveals lakes a major source of prehistoric methane
A team of scientists led by a researcher at the University of Alaska Fairbanks has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age. view more (2007-10-26)
Methane doesn't necessarily mean life on Mars, says Dartmouth study
Two Dartmouth researchers have weighed in on the debate over whether the presence of methane gas on Mars indicates life on the red planet. Mukul Sharma, Assistant Professor of Earth Sciences, and Chris Oze, a postdoctoral fellow, argue that the Martian methane could have been produced by inorganic processes just as easily as by bacteria. view more (2005-06-08)
Greenhouse gas from English streams
English chalk streams are less healthy than we thought and are potentially even contributing to global warming, said Dr Mark Trimmer at a Science Media Centre press briefing today. view more (2007-12-11)
Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere. view more (2008-01-17)
Methane found in desert soils bolsters theories that life could exist on Mars
Evidence of methane-producing organisms can be found in inhospitable soil environments much like those found on the surface of Mars. view more (2005-11-01)
Warming ocean contributes to global warming
The warming of an Arctic current over the last 30 years has triggered the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed. view more (2009-08-17)
