The thermophilic plants expansion damages the permafrost.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Scientists at Tomsk University have found out that shrubs accelerate the permafrost melting in the tundra. As reported on the website of the Russian Science Foundation, the high bioproductivity of plants increases the temperature of the soil, reduces humidity and increases the permafrost depth by three to four times.

Due to climatic changes in the tundra, the expansion of rather thermophilic shrubs, for example, alder, has begun. Plants keep snow in winter, which keeps the soil warm. The temperature difference in places with and without shrubs can be 10-15 degrees Celsius. Scientists plan to study what area in the Arctic the shrubs have already occupied and how wide they can grow.

Earlier, scientists warned about new natural anomalies, we also talked about the fact that the Arctic heats up faster than other regions.
