Melting Arctic glaciers reveal new resources of planet-warming methane


Chickening out glaciers within the Arctic are exposing groundwater springs containing very excessive concentrations of methane, which would possibly upload vital amounts of the greenhouse gasoline to the ambience.

“It is a novel methane emissions pathway that we hadn’t known earlier than,” says Gabrielle Kleber on the College of Cambridge.

Masses of springs have emerged on the base of backing out glaciers around the Norwegian Arctic archipelago of Svalbard. Kleber used to be intrigued via the springs, partially as a result of their “sulphuric, eggy scent”. Even though methane is odourless, microbes in high-methane prerequisites on occasion produce gases like hydrogen sulphide that experience this unique scent. “We knew …
