Thawing Permafrost Could Release Enormous Amounts of Carbon and Methane

This article raises concerns about the release of carbon and methane from decomposed organic matter that has been in storage from thousands of year in permafrost. The thawing of some permafrost increases global warming which causes more permafrost to thaw. Scientists are increasing their estimates of the potential emissions from thawing permafrost. Its a situation in which once it reaches a certain point it is irreversible.
