Behold, I plunge my hands in fire! I feel no heat!

Forty years ago, a vast molten cavity known as the Darvaza crater – nicknamed the "door to hell" – opened up in the desert of north Turkmenistan, and has been burning ever since. Last year, George Kourounis became the first person to descend to the bottom of the crater. [more inside]

Burp.

A new article in Nature warns that "the costs of a melting Arctic will be huge", thanks in part to the likely release of "a 50-gigatonne (Gt) reservoir of methane, stored in the form of hydrates" beneath the East Siberian Arctic Shelf, "either steadily over 50 years or suddenly". An abrupt release is "highly possible at any time", says Natalia Shakhova of the University of Alaska at Fairbanks, who has observed plumes of methane up to a kilometre wide bubbling to the surface in the area.

A Song of Ice on Fire

Methane hydrates, also known as clathrates, are crystalline ice structures which trap molecules of natural gas. They are fairly ubiquitous in near-shore seafloor sediments, where methane from decaying organic matter is trapped in an ice structure at low temperature and high pressure. Though methane hydrates are believed to contain substantially more natural gas than conventional deposits, extraction of the natural gas was thought to be impractical. Until now. [more inside]

The Wreck in Witch's Hole: the sole casualty of Britain's Bermuda Triangle

To a fisherman, all areas of the sea have names, just as a farmer will name his fields or streets have formal and informal names. For instance, there is the Witch's Ground, an area where the fishing is good, but the bottom is very rough and gear can easily be damaged or lost. Or if you're really unlucky, an undersea methane burst might make water less dense, and the sea could swallow your whole trawler. [more inside]

Methane and Climate Change

Climate change could be accelerated by 'methane time bomb' Atmospheric methane levels began rising in 2007, when an Arctic heatwave caused sea ice to shrink significantly. Now new preliminary results suggest levels have continued to rise through 2008 and 2009. The new figures [were] disclosed [earlier this week] at the start of a two-day conference on greenhouse gases at the Royal Society in London. (more here; via).

Has life on Mars been confirmed?

A British tabloid claims that NASA will today announce the probable presence of life on Mars. Planetary and atmospheric scientists from NASA's Mars program will address a press conference at 2PM EST, apparently about concentrated methane plumes that bloom and dissipate [pdf]. There was a false alarm about a similar briefing a few months ago; is this the real deal?

China and India have reported massive finds of frozen methane

China and India have reported massive finds of frozen methane clathrate off their coasts and, along with Japan and other countries, are spending large sums to develop it into a new source of fossil energy. This is important for developing countries as there may be more frozen methane in the world than all the oil, gas and coal combined, and it is available right off their coasts. Some believe it can be extracted in a carbon neutral manner, but methane is a powerful greenhouse gas and the scarily named clathrate gun hypothesis provides some fuel for thought about digging this stuff up.

Titanic Pirates of Methane Seas

Titan Sea and Lake Superior
This movie, comprised of several detailed images taken by Cassini's radar instrument, shows bodies of liquid near Titan's north pole. These images show that many of the features commonly associated with lakes on Earth, such as islands, bays, inlets and channels, are also present on this cold Saturnian moon. They offer strong evidence that larger bodies seen in infrared images are, in fact, seas. These seas are most likely liquid methane and ethane.

Cow 'emissions' more damaging to planet than CO2 from cars

Livestock's Long Shadow, a new UN FAO report (full report) says livestock (cows, pig, sheep, etc.) generate more CO2 than all forms of transportation (cars, planes, etc) combined, with the worlds live stock expected to double by 2050.

a mighty wind

The Fart Heard Round the World. An extraordinary performer, who farted for his living for 20 years, Le Pétomane (YouTube) was the highest paid stage artist of his time in 1897 France. He farted songs, impressions of people, the 1906 San Francisco earthquake and farm animals, among other things. The management of Moulin Rouge had to hire nurses to help members of the audience who passed out laughing so hard. He was pusued for many years by an obsessed doctor. Two movies were made about his life in English, the 1979 short film (33 minutes) of Le Pétomane (Google video) and in 2005 Parti Avec Le Vent, which translates as Gone With the Wind. [more]

Plants Exhale Methane, Contribute to Warming

Grasses and other green growth may produce 10 to 30 percent of Earth's annual methane output. German researcher Frank Keppler reports in Nature [reg req] that living plants give off between 60 and 240 million tonnes of methane per year, which may mean that the use of carbon sinks to offset CO2 emissions may need to be rethought.

Stop it or perish - get it ?

"Killer in Our Midst : Methane Catastrophes in Earth's Past and Near Future" (a free net book) - During the greatest extinction pulse known to have happened in the history of life on Earth - the Permian catastrophe - 90% of then existing species perished. This astonishingly well written, authoritative, free book may be the most important thing you will ever read on the net or off of it : it explains in great detail an inevitable Methane catastrophe, if humans do not stop adding CO2 to the Earth's atmosphere, during which "not only would a considerable percentage of existing plants and animals be killed off, but a large percentage of the human population as well" (or the whole species). In the worst scenarios the atmosphere itself could become poisonous to Oxygen breathing life. Mundane laws of physics, expressed in impending Methane Hydrate release, dictate to humanity : cut CO2 release or perish. Simple.

Microbes vs. Peak Oil

Real-Time Biological Natural Gas Generation. A research lab has discovered that microbes living in Wyoming's Powder River Basin are generating methane (natural gas) through their natural metabolism of local coal beds. In relation to the many Peak Oil discussions here, could be way to get more energy for the future. (via SpaceDaily.com)

Life On Mars's Meethane Traces Thought To Be Detected

Life on Mars? Methane has been found in the Martian atmosphere which scientists say could be a sign of present-day life on Mars. It was detected by telescopes on Earth and has recently been confirmed by instruments onboard the European Space Agency's orbiting Mars Express craft. Methane lives for a short time in the Martian atmosphere so it must be being constantly replenished. There are two possible ways to do this. Either active volcanoes, but none have yet been found on Mars, or microbes. The Independent has it as Methane find on Mars may be sign of life. The second group to detect signals of methane in the Martian atmosphere is led by Michael Mumma of Nasa's Goddard Space Flight Centre in Maryland, who used powerful spectroscopic telescopes based on Earth. This team is even believed to have detected variations in the concentrations of methane, with a peak coming from the ancient Martian seabed of Meridiani Planum, which is being explored by a Nasa rover. This could indicate a subterranean source of methane which is pumping out the gas, either due to some residual geological activity or because of the presence of living organisms producing it as a waste gas. Asked whether the continual production of methane is strong evidence of a biological origin of the gas, Dr Mumma said: "I think it is, myself personally." As to how...
