An analysis of ancient Greenland ice suggests a spike in the greenhouse gas methane about 11,600 years ago originated from wetlands rather than the ocean floor or from permafrost, a finding that is good news according to the University of Colorado at Boulder scientist who led the study.Methane bound up in ocean sediments and permafrost, called methane clathrate, has been a concern to scientists because of its huge volume, greenhouse gas potency and potential for release during periods of...
According to scientists, Greenland's icesheet has revealed a store of methane that appears to be more stable that previously thought, easing tensions over a rapid rise in global temperatures. Vast amounts of methane, a gas that is 25 times more powerful than carbon dioxide (CO2) at trapping heat within the atmosphere, is trapped within the permafrost in the far northern hemisphere, and in seabed deposits called clathrates. Scientists have feared that the release of the clathrate reservoir...
