More GHGs Under Arctic

The frozen Arctic soil could contain double the greenhouse-gas-producing organic material than previously estimated. After analyzing samples from Alaska, researchers from the University of Alaska predicted slight increase in the atmospheric temperature could cause the Arctic tundra to melt, exposing the organic material. From a carbon sink, the Arctic soil could then become a source of greenhouse gases. The northern reaches of Europe and Russia also contain a comparable amount of greenhouse gases, which, if released, would fuel global warming.
