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 ...

The Arctic tundra contains a number of low shrubs and sedges as well as reindeer mosses, liverworts, grasses, lichens, and around 400 types of flowers. There are also a number of animals that call ...

Arctic foxes (Vulpes lagopus), known for their excellent hunting skills are small, adaptable mammals found in the harsh conditions of the Arctic tundra.They are well-equipped for surviving extreme ...

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 warming up and that's causing long-frozen ground to melt as well as an increase in wildfires. The region is "now emitting more carbon that it stores, which will worsen climate ...

But warming air temperatures in the Arctic are breaking down permafrost across the tundra, in some cases, severely. The Arctic report, for example, showed Alaskan permafrost temperatures in 2024 ...

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 ...

The Arctic tundra, a critical “carbon sink” for thousands of years, is now releasing more of the greenhouse gas than it takes in, scientists have announced.

According to NOAA's report, wildfires in the Arctic have increased in burned area, intensity, and associated carbon emissions, playing a central role in the tundra's transition to a net carbon source.

The Arctic is now a carbon source, instead of a carbon sink, according to a new report released by NOAA. Warming temperatures, melting permafrost and increased wildfires have contributed to the ...

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 ...

Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution. As wildfires increase and hotter temperatures melt long-frozen ground, the ...
