According to NOAA's report, wildfires in the Arctic have increased in burned area, intensity, and associated carbon emissions ...

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 ...

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 ...
