Wetlands likely source of methane from ancient warming event
An expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago, according to an international research team led by Scripps Institution of Oceanography at UC San Diego. view more (2009-04-24)
Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions. view more (2007-01-31)
A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years. view more (2007-09-19)
Heaps of climate gas - Pasturing cows convert soil to a source of methane
The cow as a killer of the climate: This inglorious role of our four-legged friends, peaceful in itself, is well-enough recognised, because, with their digestion, the animals produce methane, which is expelled continuously. view more (2007-10-15)
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...

Microbes under Greenland Ice may be preview of what scientists find under Mars' surface
A University of California, Berkeley, study of methane-producing bacteria frozen at the bottom of Greenland's two-mile thick ice sheet could help guide scientists searching for similar bacterial life on Mars. view more (2005-12-15)
Deep sea methane scavengers captured
Scientists of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and the California Institute of Technology (Caltech) in Pasadena succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. view more (2008-05-14)
Focus on methane to save the planet
SMALL print in the Kyoto Protocol threatens to make global warming more severe than it need be over the next 10 years or so. An obscure rule is discouraging countries from applying cheap technologies that could dramatically curb global warming in the short term, warns a British climate scientist.... view more...

Hydrocarbons in the deep Earth?
The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. view more (2009-07-27)
Drizzly mornings on Xanadu
Noted for its bizarre hydrocarbon lakes and frozen methane clouds, Saturn's largest moon, Titan, also appears to have widespread drizzles of methane, according to a team of astronomers at the University of California, Berkeley. view more (2007-10-12)
Does your physics teacher set fire to dustbins in lessons?
Does your physics teacher set fire to dustbins in lessons? Bristol-based teacher Lucien McLellan (41) who teaches at Downend School did just that, and has been awarded the 'Best Demonstration' prize at the international festival Physics on Stage 3, in Noordwijk, The Netherlands which ran between 8 - 15 November 2003. Beating 300 other teachers to... view more... (2003-11-18)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)

Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
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)
Methane gyrations last 2,000 years show human influnece on atmosphere
Humans have been tinkering with greenhouse gas levels in Earth's atmosphere for at least 2,000 years and probably longer, according to a surprising new study of methane trapped in Antarctic ice cores conducted by an international research team. view more (2005-09-09)
Halting methane squanderlust
The pipes that rise from oil fields, topped with burning flames of natural gas, waste fossil fuels and dump carbon dioxide into the air. In new work, researchers have identified the structure of a catalytic material that can turn methane into a safe and easy-to-transport liquid. The insight lays the foundation for converting excess methane into a... view more... (2008-05-22)

Methane shock tilted the Ocean - Nature article of a marine scientist from Bremen
Up until now, scientists had to rely upon assumptions: at some point in time, on the boarder between the Paleocene and the Eocene 55 million years ago, the ocean lost its balalance. All of a sudden about 70% of all the foraminifera living on the seafloor became extinct. Just as suddenly, new, up until then unknown species of these... view more... (1999-10-19)
