Recent research in the Greenland Sea was aimed at investigating the release of methane from the seafloor—one of the many potential apocalyptic positive feedback pathways which lead from an initial warming instigated by anthropogenic greenhouse gas emissions.
Researchers were reporting that contrary to expectations, the release of methane from the seabed was found not to be a recent phenomenon (i.e., a result of global warming), but instead that many of the gas outlets had been active for long before local ocean temperatures have been rising. |
