Permafrost saturate the Earth's atmosphere with carbon

University of Michigan scientists have found that the carbon in the permafrost in the Arctic is extremely sensitive to sunlight. When sunlight on the surface of the frozen ground last very quickly begin to emit the gas carbon dioxide (CO?), Which, in turn, actively contributes to global warming.

In the study of the Arctic regions of Alaska, in which there is permafrost melting, seriously affecting the topography of the ice cover, it was observed that sunlight stimulates the bacteria to the active processing of carbon contained in the soil. Being processed up to 40% of the total carbon storage in the ground in this region! This is far more than previously estimated.

Thus, the Arctic, store unimaginably vast reserves of organic carbon for thousands of years, can be a source of abundant influx of greenhouse gases in the Earth's atmosphere, which, in turn, will only spur melting permafrost and increase the further extraction of CO?. The volumes allocated to the melting of the frozen soil, will be comparable with the volume of carbon dioxide emitted into the atmosphere is the burning of all fuels.
