Arctic tundra is now warming the world instead of cooling it
The news that the frigid Arctic tundra ringing the polar region has switched from being a net absorber, or "sink," of planet-warming greenhouse gases to a net emitter, or "source," indicates the Arctic is on the brink of further,
The tundra keeps burning and it’s transforming the Arctic
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.
Arctic Tundra Has Long Helped Cool Earth. Now, It’s Fueling Warming.
Wildfires and thawing permafrost are causing the region to release more carbon dioxide than its plants remove, probably for the first time in thousands of years.

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.
The Arctic tundra was a carbon sink. Now it contributes to global emissions
Wildfires and thawing permafrost are causing the Arctic region to release more carbon dioxide and methane than its plants remove.
