Arctic tundra now emitting more carbon gases than it absorbs, annual report says
For millennia, the tundra regions of the Arctic drew in carbon from the atmosphere and locked it in permafrost. That is the case no more, according to an annual report issued on Tuesday by the National Oceanic and Atmospheric Administration.

Fires, intensified by climate change, release carbon trapped in soil and plants. More frequent infernos have now transformed the tundra into a net source of carbon dioxide emissions. It’s a dramatic shift for the Arctic, and one that will make the planet even hotter.
