Two decades of summer warming in an Alaskan tundra ecosystem increased plant biomass and woody dominance, indirectly increased winter soil temperature, homogenized the soil trophic structure and ...

As the Arctic tundra warms, soil microbes likely will ramp up CO 2 production. Understanding the tiny organisms' behavior could help with climate change predictions.

On the Arctic tundra, vegetation has just a short season to photosynthesize, and it is small, lacking the type of big leaves that draw in a lot of carbon dioxide.

After storing carbon dioxide for millennia in frozen soil, the Arctic tundra has now become a source of emissions. “Our observations now show that the Arctic tundra, which is experiencing ...

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 ...

The Arctic tundra is now emitting more carbon dioxide than it absorbs, according to the latest Arctic Report Card released by the US National Oceanic and Atmospheric Administration (NOAA).

Plant life determines soil bacteria diversity in the Arctic tundra Peer-Reviewed Publication. Research Organization of Information and Systems ...

The Arctic permafrost region as a whole — which encompasses tundra and forests — has become carbon neutral over the past 20 years, meaning it’s neither absorbing nor releasing excess CO2 ...

A better understanding of the high levels of mercury pollution in the Arctic tundra. Scientists have been searching for over two decades to explain how the Arctic is contaminated with toxic ...

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 ...
