Latest Methane clathrate Stories
Despite the reduced amount of carbon dioxide given off by the burning of natural gas, increasing use of it and decreasing our reliance on coal would do little to slow down global climate change, claims a new study set for publication in the journal Climatic Change Letters. The research, led by Tom Wigley, a senior research associate at the National Center for Atmospheric Research (NCAR), "underscores...the complex and sometimes conflicting ways in which fossil fuel burning affects...
ORLANDO, Fla., Aug. 15, 2011 /PRNewswire/ -- GDT TEK, Inc. (OTC: GDTK) today announced that its 50% owned subsidiary Steriwave-GDT Tek has filed a patent application for a system that safely removes and captures methane hydrates from undersea reserves. The main design of the Steriwave-GDT Tek subsea open pit drilling/extraction concept is to provide maximized safety versus environmental issues. Methane hydrates, which form at low temperature and high pressure, are found in sea-floor...
Researchers have pinpointed the timing of the start of an ancient global warming episode known as the Paleocene-Eocene thermal maximum (PETM). The early part of the Cenozoic era witnessed a series of transit global warming events called hyperthermals. The most severe of these was the PETM at the Paleocene-Eocene boundary, which took place around 56 million years ago. Over a 20,000-year period, ocean temperatures rose globally by about 41 degrees Fahrenheit. The team said one...
Marine scientists cast doubt on Thursday about an earlier study that found bacteria had consumed nearly all of the methane that leaked into the Gulf of Mexico amid last year's BP oil spill.Calling the widely-publicized study's findings "ambiguous" and "unconvincing", they said the methods used were flawed and warranted further review."We find the complete methane oxidation hypothesis unconvincing," wrote Samantha Joye and colleagues from 12 other institutions in a...
A technical comment published in the current (May 27) edition of the journal Science casts doubt on a widely publicized study that concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well.The debate has implications for the Gulf of Mexico ecosystem as well as for predictions of the effect of global warming, said marine scientist and lead author Samantha Joye, University of Georgia Athletic Association Professor in Arts and...
Craig Scott Goldsmith, author of "Uninhabitable: A Case for Caution," says, "It is time for America to step up or step aside." (PRWEB) April 20, 2011 In preparation for Earth Day 2011, Craig Scott Goldsmith, author of "Uninhabitable: A Case for Caution," has sent an open letter to humanity and its leaders cautioning the detrimental effects of releasing Co2 into the atmosphere. Goldsmith says humans are accelerating Co2 emissions through overpopulation, the use of...
Scripps researchers document the history of sudden global warming events, impacts on marine lifeBursts of intense global warming that have lasted tens of thousands of years have taken place more frequently throughout history than previously believe, according to evidence gathered by a team led by Scripps Institution of Oceanography, UC San Diego researchers.Richard Norris, a professor of geology at Scripps who co-authored the report, said that releases of carbon dioxide sequestered in the...
Researchers develop technique to measure methane gas from cattleMethane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the atmosphere...
Paper has implications for oxygen depletion, provides photographic evidence of plumesA new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 tons of gaseous hydrocarbons were emitted into the deep ocean. The authors conclude that such a large gas discharge"”which generated concentrations 75,000 times the norm"”could result in small-scale...
An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas.John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates.The study, published in the journal Science, indicates that methane gas...
