Novel source of the strong greenhouse gas nitrous oxide found in Siberian permafrost
A previously unknown source of the strong greenhouse gas nitrous oxide has been found in East Siberian Yedoma permafrost. Published in Nature Communications today, the observation was made by an international group of researchers, with the lead of researchers from the University of Eastern Finland.Nitrous oxide (N\2\O) is the third-most important greenhouse gas after carbon dioxide and methane, and per unit mass an almost 300 times stronger warming agent than carbon dioxide. It is produced in soils as a result of microbial activity. The discovery of nitrous oxide release from the late-
