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...

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 Rata and Euan Nisbet of Royal Holloway’s... 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. From the time of its arrival at Mars, the Mars... 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 thaw lakes and into the atmosphere as methane, a... view more...

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 vegetation composition and subsequent increase in... 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-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
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 move. view more (2007-04-16)
Discovery of methane reveals Mars is not a dead planet
A team of NASA and university scientists has achieved the first definitive detection of methane in the atmosphere of Mars. This discovery indicates the planet is either biologically or geologically active. view more (2009-01-16)
Methane Eruptions On The Sea Floor - Science article: New evidence, new methods
Methane is a highly potent greenhouse gas. In its solid, ice form, called methane hydrate, it is stored in large amounts below the sea floor. Some signs indicate that there have been repeated intense undersea methane emissions over the course of the Earth's history. Often, these emissions appeared to be linked to climate changes, species... view more... (2003-02-19)
Mars, methane and mysteries
Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. view more (2009-08-10)
Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. view more (2005-12-06)
Ancient climate switch could signify sharp increase in today's global temperature
A paper published in today's Nature suggests that global warming could rapidly accelerate due to a positive feedback mechanism caused by water vapour or rainfall. The paper, which examines a period of rapid climate change 55 million years ago, during the Paleocene and Eocene, offers a clear indication of how gradual global warming can rapidly... view more...

"Rational" Meccano
Nanofibrous carbon is interesting by itself: it consists of carbon fibres of 3 to 500 nm in diameter. These fibres can form " cylinders" (which make almost finished polymeric nanotubes), or a system of cones stowed one into the other at a certain angle to the fibre axis, or simply "wrapping package" - this is driven by the type of applied catalyst... view more...

'Hellish' hot springs yield greenhouse gas-eating bug
A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming. view more (2007-12-07)
