New research indicates a 'troubled' greenhouse is brewing

...which lasted less than half a million years, was a catastrophic release of natural gas from undersea ices and permafrost. "In a remarkable parallel to modern hydrocarbon pollution of the atmosphere, this natural methane oxidized to carbon dioxide and created a global greenhouse event," he explains. "The past met...
