A third of the Arctic is now emitting climate-changing greenhouse gasses after thousands of years of storing them, according ...

The Frozen Ground Under Threat Permafrost is like Earth's ancient freezer, stretching over vast regions, mainly near the North and South Poles. It holds soil, rocks, and sub-zero water, remaining ...

"The fact that we can't [determine whether it's wolf or dog] might suggest that it's from a population that was ancestral to ...

Other reasons may include vegetation dieback (the gradual death of plant tissue) and the growing frequency of permafrost thaw. In tundra regions, average annual soil temperatures are trending toward ...

The authors suggest one of the main drivers of the tundra’s shift from CO2 absorber to emitter could be thawing permafrost, which covers almost half of Canada’s land mass. “This is not ...

A relatively small amount of groundwater trickling through Alaska's tundra is releasing huge quantities of carbon into the ...

“First, it will damage and degrade permafrost and the tundra landscape faster and create lots of issues for people living there.” Before visiting, Fong’s team analyzed data using high-resolution ...

For millennia, the Arctic-boreal zone has acted as a critical carbon reservoir, locking away vast amounts of carbon dioxide ...

"The most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise," researcher Sue Natali said.

Parts of the Arctic tundra are now releasing more planet-warming gases than they absorb, an international study published Tuesday suggests, upending a ...

A relatively small amount of groundwater trickling through Alaska's tundra is releasing huge quantities of carbon into the ocean, where it can contribute to climate change.
