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 automobiles and by...

Scripps researchers document the history of sudden global warming events, impacts on marine life Bursts 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 cattle Methane 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...

Paper has implications for oxygen depletion, provides photographic evidence of plumes A 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...

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...

No clathrate gun 40,000 years ago rapid warming led to an increase in methane concentration. The culprit for this increase has now been identified. Mainly wetlands in high northern latitudes caused the methane increase, as discovered by a research team from the University of Bern and the German Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. This result refutes an alternative theory discussed amongst experts, the so-called "clathrate gun hypothesis". The...

Thawing by climate change of subsea layer of permafrost may release stores of underlying, seabed methane A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov. The research results, published in the March 5 edition of the journal Science,...

Scientists from the Marine Biogeochemistry and Geology and Geophysics sections of the Naval Research Laboratory (NRL) organized and led a team of university and government scientists on an Arctic expedition to initiate methane hydrate exploration in the Beaufort Sea and determine the spatial variation of sediment contribution to Arctic climate change. Utilizing the U.S. Coast Guard Cutter Polar Sea as a research platform, three cross-shelf transects were surveyed and sampled off Alaska's...

Scientists worry that rising global temperatures accompanied by melting permafrost in arctic regions will initiate the release of underground methane into the atmosphere. Once released, that methane gas would speed up global warming by trapping the Earth's heat radiation about 20 times more efficiently than does the better-known greenhouse gas, carbon dioxide. An MIT paper appearing in the Journal of Geophysical Research online Aug. 29 elucidates how this underground methane in frozen regions...
