Spiking temperatures in the Arctic are rapidly melting glaciers. Scientists are now worried about underground methane, a potent greenhouse gas, leaking up to the surface.
Permafrost, yes, but I don’t know if the land under glaciers had been included even though it might still be permafrost.
When I hear “permafrost”, I think not of land under glaciers, but the underground layer of ground that stays below freezing even when the topsoil thaws in summer.
This doesn’t seem like news to me …
Haven’t we known this for at least a decade?
