Researchers have confirmed the widespread release of ancient carbon from melting Arctic permafrost in what could be the lit fuse on a climate-change bomb. A paper published this week in Nature Geoscience has released the first measurements of greenhouse gases from permafrost under Arctic lakes. The melt often takes place in Arctic lakes where liquid water thaws long-frozen soil. “I would go out after the ice formed, look at the lake ice surface and see bubbles. “There’s a lot of interest in what the fate of that permafrost carbon is.”
