The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon ...

This article was originally featured on High Country News. Chunks of carbon-rich frozen soil, or permafrost, undergird much of the Arctic tundra. This perpetually frozen layer sequesters carbon from ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...

Stand on the tundra in Alaska and it looks like nothing special. A vast, flat plain of amber grass, shallow ponds, and dark soil stretching to the horizon. No obvious drama, no visible crisis. But a ...

Chunks of carbon-rich frozen soil, or permafrost, undergird much of the Arctic tundra. This perpetually frozen layer sequesters carbon from the atmosphere, sometimes storing it for tens of thousands ...

Climate change is warming the Arctic tundra about four times faster than the rest of the planet. Now, a study suggests that rising temperatures will spur underground microbes there to produce more ...

The boreal forest, covering much of Canada and Alaska, and the treeless shrublands to the north of the forest region, may be among the worst impacted by climate change over the next 500 years, ...

From Alaska to Siberia, the Arctic is changing so rapidly that there is no "normal" there now, scientists warn. The consequences reach across the globe. The Arctic tundra now releases more carbon than ...
