Arctic tundra vegetation is mostly limited due to many inhospitable conditions. Tropical alpine tundra vegetation consists of a variety of short shrubs, grasses, and perennials; ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.; Wildfires and permafrost thaw ...

The tundra biome is the coldest and one of the largest ecosystems on Earth. It covers about one-fifth of the land on the planet, primarily in the Arctic circle but also in Antarctica as well as a ...

Ecologist Isla Myers-Smith researches how tundra plants respond to climate change and what it means for future ecosystems. While she's mostly worked in the Canadian Arctic, for the last two years ...

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 ...

Tundra describes the Arctic’s tree-less plains, where shrubs, grasses, and mosses grow and take in carbon dioxide through photosynthesis. Plants eventually release that CO2 back into the ...

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 ...

A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that's typically known for extreme cold, little precipitation and a ...

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 ...

Here are some key takeaways from this year's Arctic Report Card: Arctic tundra: carbon sink to carbon source. Permafrost is full of carbon that has been locked away by plants over millennia.

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 ...
