Climate-change trigger? Degrading Arctic ice may release planet-warming methane
By | Published: May 31, 2008
Associated Press: Global warming could release long-dormant stores of methane gas trapped beneath the Arctic permafrost – causing an abrupt and catastrophic climate change like one that occurred 635 million years ago that ended the last great ice age, University of California-Riverside researchers have determined. Back then, the sheets of ice that covered Earth started to collapse, releasing methane gas that warmed the planet and caused the ice to retreat over a period of 100 to 1,000 years, said …
