Thanks for your question!
Permafrost is ground frozen (its temperature is below 0 ° C) permanently for at least two consecutive years.
The cause of the permafrost melting is the increase in temperature, and this, in a sufficiently long and pronounced way. The cause of this increase in temperature is climate change. Indeed, these cause a warming of the global climate which is particularly rife in the polar regions (where permafrost is mainly distributed).
The consequences of melting permafrost are multiple. We note in particular the disappearance of certain habitats such as the tundra, the appearance of cracks, the destabilization of structures built on the permafrost, the disappearance of an indigenous way of life, and, even worse, the release of gas (greenhouse effect (which reinforce global warming in a vicious cycle)).
