Mummy DNA reveals surprising clues
From ABC Science, 30 May 2017: Arctic peatlands may become a substantial source of a greenhouse gas 300 times more potent than carbon dioxide when they thaw, a new study suggests. The study by a team of Scandinavian scientists indicated that thawing permafrost could release nitrous oxide (N2O) — also known as ‘laughing gas’ — … Continue reading Arctic peatlands may release potent greenhouse gas as permafrost thaws
