Northern US soil carbon reservoirs vulnerable to global warming, says USGS
Mounting evidence shows that soil carbon is increasingly contributing larger amounts of carbon dioxide (CO2) to the atmosphere as a result of warming, permafrost degradation, and complex climate-biogeochemical interactions. Northern soils are known to harbor large amounts of carbon in the zone between the moss surface and the permafrost or mineral soil boundary.
