Rapid climate change is upending plant communities in the Arctic, with species flourishing in some areas and declining in others, according to a new study in Nature. The decades-long investigation, ...

But in the upper layers of soil, around 1,700 types of plants find a way to flourish. The Arctic tundra contains a number of low shrubs and sedges as well as reindeer mosses, liverworts, grasses ...

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 ...

Rapid climate change is upending plant life in the Arctic. A new study in Nature shows how one of the most fragile ecosystems on Earth is changing as warming is up to four times faster in the ...

The Arctic tundra is now emitting more carbon dioxide than it absorbs, according to the latest Arctic Report Card released by ...

With the Arctic warming faster than the global average, researchers at UBC and the University of Edinburgh have made an important discovery about tundra plants and how they are adapting faster ...

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 ...

These changes have pushed the tundra ecosystem over an edge. Susan Natali and colleagues found that the Arctic tundra region is now a source – not a sink, or storage location – for carbon dioxide.

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 ...

Green summer tundra and the rolling Mulgrave Hills in northwestern Alaska's Cape Krusenstern National Monument are seen on July 11, 2011. The Mulgrave Hills are the farthest west extension of the ...

Wildfires and thawing permafrost are causing the Arctic region to release more carbon dioxide and methane than its plants remove. The tundra is now a global carbon emitter. Cladonia stellaris ...
