Permafrost — the permanently frozen ground that underlies much of the arctic land surface — is thawing in many parts of the arctic. Permafrost is soil and sediment that are frozen more than two consecutive years, while the active layer is the upper part of the soil environment that thaws . 24 percent of the land in the northern . Globally, these frozen soils hold an estimated 1500 billion tons of carbon. For example, in fairbanks, alaska, the soil is frozen just some 30 to 40 centimeters below the surface, and in fact, .
Advancing understanding of processes controlling permafrost dynamics and the impacts on ecosystems, infrastructure, and climate feedbacks.
Permafrost — the permanently frozen ground that underlies much of the arctic land surface — is thawing in many parts of the arctic. In areas not overlain by ice, it exists beneath a layer of soil, rock . In recent years, climate scientists have warned thawing permafrost in siberia may be a "methane time bomb" detonating slowly. Exposed yedoma permafrost exposed along an eroded arctic coast. 24 percent of the land in the northern . Permafrost is ground that remains frozen for two or more years. Water on the surface, from melting snow, summer rains, and melting ground ice, cannot get through permafrost. Globally, these frozen soils hold an estimated 1500 billion tons of carbon. Permafrost exists where the ground stays at or below 0° celsius (32° fahrenheit) for at least two years in a row.
