Extractions: Subak, S., 1993, Natural greenhouse gas accounts: current anthropogenic sources and sinks: Climatic Change, v. 25 p. 15-44. This article presented a study of the concentrations of greenhouse gases in the industrialized and developing regions. Within this study, it was not only the goal of the author to determine the amount of particular greenhouse gases in the atmosphere of the region, but also to determine and trace their anthropogenic sources. The greenhouse gases of carbon dioxide, carbon monoxide, methane, nitrous oxide, and halocarbons, were traced to such human activities as fossil fuel consumption, livestock abundance, agricultural tendencies, cement production,etc... It was shown that not only highly industrialized regions that consume large quantities of fossil fuels contribute to the amount of greenhouse gases that are released into the atmosphere, but developing nations as well. Within this study, developing nations share the responsibility for the release of these greenhouse gases which contribute to global warming.

Paragraphs billion tonnes of carbon from fossil fuel, if the organic matter, and leaking fromnatural gas resevoirs, can be trapped in and below hydrates over thousands http://www.autobahn.mb.ca/~het/paras.html
Extractions: The Carbon War These figures for carbon in fossil-fuel deposits have been refined over the years, but the basic picture has not changed. As this book goes to press, the IPCC estimate for the total amount of fossil fuel 'resource' the quantity realistically recoverable, as opposed to total deposits exceeds 4,000 billion tonnes, over three-quarters of it coal. To hike the global average temperature to a dangerous 2 (degrees) C above pre-industrial levels, we would have to emit less than 220 billion tonnes of carbon from fossil fuel, if the climate sensitivity is at the upper boundary of the estimated range, and little is done to stop tropical deforestation." -Jeremy Leggett The Carbon War, Page 59 The Carbon War "A methane hydrate is a solid, ice-like mixture of water and methane, which forms when temperatures are low and pressure sufficiently high. The methan molecules are literally trapped, under pressure, in a cage of water molecules. A hydrate resembles ice, but isn't ice, the water crystallizes differently, and hydrates can form above freezing point if the pressure is sufficiently high. Hydrates will form, for example, if gas is pumped under pressure through pipelines in cold conditions, clogging them up. They will also form under sediment or seawater, and in cold enough conditions, will do so at fairly shallow depths. Methane generated from organic matter, and leaking from natural gas resevoirs, can be trapped in and below hydrates over thousands of years. But if the temperature in the surrounding water rises to the point where methane hydrate becomes unstable, methane gas is released at once."
World Oil: Gas Hydrate Research Heats Up If we encounter a good accumulation of natural gas hydrates, we could develop itwith existing technology, said WJA Swinkels, a member of Shell s gas hydrate http://www.findarticles.com/cf_dls/m3159/6_220/54989068/p1/article.jhtml
Extractions: Most engineers are familiar with hydrates as a production impediment. For the uninitiated, gas hydrate is a strange, frozen-like solid form of natural gas that is created whenever certain high-pressure and low-temperature conditions are met. It occurs in nearly all of the world's offshore basins and some permafrost areas. Hydrates present a geo-hazard for drilling and platform siting. They can form in subsea flowlines, pipelines and well-head equipment, and solutions are costly. This aspect of hydrates is being investigated at the Rocky Mountain Oilfield Testing Center. Japan has taken the lead in gas hydrate exploration, perhaps due to a lack of options. In late 1999, JNOC is scheduled to drill its first hydrate exploration well. Last fall, a group from Shell International Exploration and Production, B.V., discussed exploitation of hydrates at a meeting in Chiba City, Japan. The consensus was that there "is nothing that we can't handle technically. If we encounter a good accumulation of natural gas hydrates, we could develop it with existing technology," said W.J.A. Swinkels, a member of Shell's gas hydrate team.

Extractions: An international team of researchers, sailing on the German research vessel RV SONNE, recently recovered a dramatic quantity of solid "methane gas hydrates" from the seafloor off Newport, Oregon. A giant TV-guided grab sampler retrieved more than 100 lb. of this remarkable material, an ice-like solid substance made of methane gas and pure water. Formed under conditions of high pressure and low temperature, the gas hydrates slowly decompose when brought to the surface releasing methane gas and water. As an impressive demonstration of their natural gas content, these snow-white 'icecubes' are flamable. The research is part of a German-U.S.-Canadian project to study fluids and gases which are being expelled from the seafloor off the Pacific Northwest and Alaska. This fluid expulsion is a global process which is active along the entire plate collision boundaries of the earth. It results from the compression of water-rich sediments which are carried piggy-back on the moving oceanic plates towards the continents. The mechanical stress building up at the collission zones, usually the deep-sea trenches, forces the fluids back to the ocean. The fluids contribute as-yet unknown quantities of certain chemicals to the oceans and atmosphere and hence are the object of intense research by all major marine science institutions from around the world.

China Geological Survey The total amount of carbon contained in natural gas hydrate exceeds the fossil fuelbased carbon by far and therefore represents a potentially important energy http://www.cgs.gov.cn/Ev/news/2003111801.htm
Extractions: ¡¡¡¡Hydrate deposits found at the seafloor, such as off the eastern North Pacific coast, in the eastern Mediterranean Sea or in the Black Sea document highly dynamic formation and dissociation processes. Fabric analyses show that natural hydrate is less dense than experimentally formed phases. It coexists with free methane which migrates upwards from beneath the hydrate stability zone. Several types of hydrate fabrics, interlayered with carbonate crusts and hemipelagic sediment clasts, are described. In most cases pure hydrate occurs in layers millimeters to several decimeters thick. On a macroscopic scale the fabric varies from highly porous, with pore diameters up to several cm, to massive with no visible pores. Bulk densities range from 0.35¨C0.75 g/cm and are inversely correlated with the pore volume. These data allow estimates for an end-member density of pure natural methane hydrate of 0.79¡À0.13 g/cm

Extractions: The demand for natural gas in the U.S. continues to grow. Its clean burning characteristics, coupled with the fact that nearly all the natural gas used in North America is produced in North America, makes natural gas an increasingly popular fuel as the nation wrestles with major energy and environmental problems including dependence on imported oil, poor urban air quality and global warming. As a result, it is forecasted that natural gas use will continue to grow in every U.S. energy sector - residential, commercial, industrial and, especially, power generation. Using natural gas to power vehicles is yet another market that has grown significantly over the past decade. Moreover, groundbreaking legislation currently under consideration by the U.S. Congress, if passed, would provide valuable tax incentives for the purchase and use of natural gas vehicles (NGVs) and natural gas fueling infrastructure. This would stimulate further growth in that market.

Extractions: These days, with global temperatures on a dangerous upward trend, discussions of energy resources can't ignore climate impacts. How might gas hydrates affect global warming due to greenhouse gases? The discovery could reduce the already flagging demand for energy conservation since price, more than good intentions, is what reins in demand for energy. Natural gas produces less carbon dioxide than either oil or coal, so substituting it may reduce greenhouse emissions. That carbon might get released accidentally - with catastrophic results. Says Steven Holbrook: "The amount of organic carbon [meaning carbon bonded to hydrogen and perhaps other elements] in these deposits is ... by far the largest such reservoir on Earth, so it is vital to understand whether that reservoir is 'locked up' or whether it exchanges carbon with the oceans and atmosphere, either through gradual or catastrophic processes." Perhaps most important: What is the fate of all that methane? Gram for gram, methane packs more greenhouse punch than carbon dioxide, so deliberate or accidental releases could accelerate global warming.

Extractions: Clathrates: little known components of the global carbon cycle What are clathrates? Clathrates are also called gas hydrates Hydrates were discovered in 1810 by Sir Humphrey Davy, and were considered to be a laboratory curiosity. In the 1930s clathrate formation turned out to be a major problem, clogging pipelines during transportation of gas under cold conditions. Gas hydrates, also called clathrates, are crystalline solids which look like ice, and which occur when water molecules form a cage-like structure ). 5.75(H of methane gas at standard conditions of temperature and pressure. In nature, one cubic meter of hydrate turns out to contain up to 164 m of methane. Recently clathrates have received attention as a possible energy source, and as playing a role in large undersea slumps which could result in dangerous tsunamis, as well as in climate variability. What is the origin of the methane in clathrates? The methane in gas hydrates is dominantly generated by bacterial degradation of organic matter in low oxygen environments. Organic matter in the uppermost few cm of sediments is first attacked by aerobic bacteria, generating CO d Where do clathrates occur naturally?
Climate Change Update -- Climate Class produces less CO2 when burned than do other fossil fuels. or landfills, for example,for fuel use, we reap natural or human disturbance of these deposits could http://www.nsc.org/ehc/climate/ccucla5.htm
Extractions: Climate Class Methane: The 'Other' Greenhouse Gas So much attention is paid to carbon dioxide as part of the greenhouse effect that people tend to overlook another critically important gas in manmade greenhouse warming methane. Methane, or CH4 (four hydrogen atoms and one carbon atom), is the main ingredient in the natural gas our home stoves use. The concentration of methane in the atmosphere is minute about 1.7 parts per million, by volume (ppmv). Thats much lower than the concentration of carbon dioxide (in 1998, just over 360 ppmv) but methane is far more efficient than CO2 at trapping heat. The Intergovernmental Panel on Climate Change estimates methanes global warming potential as 21 times more than CO2 on a pound-for-pound basis over 100 years. Methane in the atmosphere has increased even faster than carbon dioxide during the industrial age to more than double its pre-industrial concentration. Current levels are the highest ever observed, even compared against air bubbles trapped in 420,000-year-old ice. The IPCC estimated in 1990 that methane accounted for some 15 percent of the manmade increase in radiative forcing during the previous decade (compared with 55 percent for CO2). Thats the bad news. Theres some good news about methane, too. Its lifetime in the atmosphere is far shorter than that of carbon dioxide hardly more than a decade, as compared with 50-200 years for carbon dioxide. That means any reductions in human emissions will have a quicker payoff in slowing global warming.
