	Permafrost is permanently frozen ground. It is starting to melt, releasing into the atmosphere previously locked-in methane and ~~CO2~~ from decomposed biomass. This creates a negative feedback loop, just like forest fires and albedo changes due to melting sea ice.		Permafrost is permanently frozen ground.
