They also though mean more greenhouse gas emissions, as CO2 and methane stored in soil get released. (treehugger.com)
While the evidence for catastrophic leakage is still equivocal, the amounts of methane stored in permafrost and ocean sediments strongly argue for a precautionary approach to the risks of widespread release. (ceassessment.org)
Despite portentous headlines — including one on the news release from the University of Alaska, Fairbanks, saying «Arctic seabed methane stores destabilizing...» — there is no evidence (yet) that what is happening is fundamentally new or destabilizing, at least according to some of the scientists most closely tracking levels and sources of this gas from the poles to the tropics.
