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... view more (2000-05-10)

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)

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)

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... 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)

Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago.   view more (2007-09-20)

Scientists Find Good News About Methane Bubbling Up From the Ocean Floor Near Santa Barbara
Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara.   view more (2007-12-21)

Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature.   view more (2006-09-08)

Did you know? The oldest organisms live in waste repositories
Some of the oldest organisms - Archaea - live in waste repositories. These microorganisms have lived on Earth for 3.8 billion years and some of them can produce methane, used as a renewable energy source. Cemagref scientists are trying to enhance their activities so that they produce methane more... view more (2003-06-11)

Methane bacteria possess pressure valve
Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems... view more (2002-10-24)

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... view more (2003-01-24)

Frozen methane chunks not responsible for abrupt increases in atmospheric methane
Icy chunks of frozen methane and water are not responsible for the periodic increases in atmospheric methane recorded in Greenland ice cores.   view more (2006-02-10)

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... view more (2001-04-25)

Mars Express confirms methane in the Martian atmosphere
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more.... view more (2004-03-30)

Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian... view more (2006-09-07)

Thawing permafrost increases greenhouse gas emission from subarctic mires
The permafrost in the mires of subarctic Sweden is undergoing dramatic changes. The part of the soils that thaws in the summer, the so-called active layer, has become deeper since 1970 and the permafrost has disappeared altogether in some locations. This has lead to significant changes in the... view more (2004-02-24)

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)

Level of important greenhouse gas has stopped growing
Scientists at UC Irvine have determined that levels of atmospheric methane - an influential greenhouse gas - have stayed nearly flat for the past seven years, which follows a rise that spanned at least two decades.   view more (2006-11-21)

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)

Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits.   view more (2006-08-25)

Predicting the weather on Titan?
Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan.   view more (2006-01-24)

CO2 storage in coal can be predicted better
CO2 storage in the ground is being considered increasingly more often in order to realise the climate and energy objectives. Dutch researcher Saikat Mazumder made it possible to better predict routes of the 'underground highways' along which gasses like carbon dioxide (CO2) and methane (CH4) will... view more (2007-04-16)
