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

Melting glaciers in Greenland are unleashing hidden methane and shifting soils from carbon sinks to warming sources.

"These holes are collapsing." Scientists issue warning after discovering concerning 'Swiss cheese' phenomenon in Arctic: 'The ...

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.

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

Arctic tundra is releasing greenhouse gases into the atmosphere as hotter temperatures melt frozen ground and wildfires increase. Arctic tundra, which has stored carbon for thousands of years, has ...

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 ...

How Arctic Amplification Starts . Greenhouse gases like carbon dioxide (CO2) and methane (CH4) allow the sun’s warming rays in through the atmosphere. A warmed Earth radiates heat back toward space.

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