World’s Biggest permafrost crater in Russia’s Far East melts as planet gets warmer

These permanently frozen plains are made up of soil, rocks and sand brought together by the ice. NASA says that permafrost is most common in areas near the North and South Poles and covers large parts of the Earth. Specifically, about a quarter of the land in the Northern Hemisphere is under permafrost. It is also interesting that even when the ground is frozen, areas of permafrost are not always covered with ice.

gateway to earth
Locals near Batagaika Crater refer to this one-kilometer-long giant as the ‘Gateway to the Earth’, a reference to Siberia. This crater which first started appearing in the 1960s. At that time these pits were formed due to the felling of the surrounding forests. Due to this the ice of the land had ended. As a result, the soil got eroded and the ground got sunk. Local resident and scientist Erel Struchkov told news agency Reuters that the locals call it a cave hidden underground. It was the first crater formed in the 1970s. Then due to sunlight and heat, it started melting and started growing. Local people have also noticed the rapid growth of the crater.

what if it melts
There is also permafrost in the circumpolar regions of Canada, Alaska, Siberia and some other places. This permanently frozen land has been acting as a carbon sink for thousands of years. If it melts, it can release a large amount of this gas. Because of this, the problem of global warming can increase. As temperatures rise, this permanently frozen layer will melt and release giga-tons of gases such as carbon and methane, as well as viruses and bacteria that are several thousand years old. As a result it will be dangerous for the areas where it is located and for the whole world.
