Methane and other greenhouse gases affect permafrost indirectly through their impact on climate. Climate change due to anthropogenic greenhouse gas emissions is the main cause of permafrost melting. Rising air temperature affects the surface temperature of the ground and soils, the hydrological cycle, the intensity of vegetation cover and other elements of the permafrost ecosystem, each of which has an impact on the state of permafrost.

A brief overview of trends in permafrost: Currently, the main international trend in permafrost protection is to monitor and obtain up-to-date scientific data on permafrost. Cryolithozone (permafrost) covers 65% of Russia's territory. It is a huge in area geological body of rocks of different composition and genesis with negative temperature. One part is perennially frozen and contains ice-cement, thin ice interlayers. The other part contains unfrozen solutions of various chemical composition.
