Permafrost DistributionThere are four ways to describe the distribution of permafrost: continuous, discontinuous, isolated, and sporadic permafrost. Even though methane constitutes only 0.00018 percent of the atmosphere, it is responsible for about one-sixth of the last few decades’ global warming. 2018 reveals that permafrost soils from the Northern pole would generate one gigaton, or 1000 million tons of methane by 2100. They provide shade for permafrost soil from direct heat of the sun, and their roots eliminate water making them better insulators. Knoblauch, C., Beer, C., Liebner, S., Grigoriev, M.N, Pfeiffer, E.M.
