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 Arctic region has shifted from storing carbon dioxide to releasing it into the atmosphere, according to the 2024 Arctic ...

“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 ...

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 ...

On Kotelnyy he’s noticed that as the permafrost thaws and settles each summer, mammoth tusks resting on a layer of ice below begin to peek out of the tundra. “Every year there’s another crop ...

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

The Arctic is set to undergo dramatic and irreversible changes in the coming years if global warming reaches 2.7°C above ...

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 ...

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.

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.
