Ground slumping in yedoma permafrost after a wildfire, in the interior of Alaska. Yedoma permafrost generally contains large ...

A third of the Arctic is now emitting climate-changing greenhouse gasses after thousands of years of storing them, according to a new study from the Falmouth-based Woodwell Climate Research Center.

Gabrielle Kleber and Leonard Magerl, postdoctoral researchers at iC3, have discovered that Arctic glaciers are leaking significant amounts of methane, a potent greenhouse gas.

For millennia, the Arctic absorbed more carbon than it emitted. That’s changed. The region is warming much faster than the rest of the planet and releasing greenhouse gases from its thawing soil ...

Arctic tundra, which has stored carbon for thousands of years, has now become a source of carbon dioxide. The new research, led by scientists at the Woodwell Climate Research Center in Falmouth ...

The annual assessment reveals that warming temperatures and increased wildfires have shifted the Arctic from a carbon sink to a net source of greenhouse gas emissions.

The following is the July 2, 2025, Congressional Research Service report, Changes in the Arctic: Background and Issues for ...

Arctic tundra, which for thousands of years was a net sink for atmospheric carbon, is now a net emitter, adding to the greenhouse gas load that is warming the earth, according to the 2024 Arctic ...

Last summer, Phoenix had 70 days with temperatures over 110. That's mainly due to human greenhouse gas emissions, but it was accelerated in part due to additional greenhouse gases from the Arctic." ...

Arctic tundra is releasing greenhouse gases into the atmosphere as hotter temperatures melt frozen ground and wildfires increase.

Arctic glaciers are leaking significant amounts of methane, a potent greenhouse gas. Gacial melt rivers and groundwater springs are transporting large volumes of methane from beneath the ice to ...
