Permafrost region covers 24% of the Earth’s total area and holds 1460-1600 Pg of carbon. A significant portion of this carbon (1035 ± 150 Pg) can be found in top three meters of the soil. With the degradation of permafrost due to the increase in air temperature in high latitudes (0.6 °C over the...
