When I think about Siberian Crater, one question always comes my mind- is the Siberian Permafrost are the reason for this huge crater? Or Is the Siberian permafrost exploding?
For the knowledge, Permafrost is a thick subsurface layer of soil that remains below at the freezing point more than two consecutive years, occurring chiefly in the Polar Regions.
A recent report suggested that methane pockets are bursting and causing the massive craters, but scientists aren’t so sure about these.
And according to the Siberian Times Article, as a result of melting permafrost, 7,000 underground gas bubbles are set to ‘erupt’ on the Yamal Island and Gydan Island. The article discriminates those small gas bubbles from immense craters in the tundra landscape but asserts that the reason behind the huge craters are, subsurface methane gas bursting as soon as global warming heats up the Earth. But that’s not the certain reason, on the basis of what scientist. Even it can be possible that the craters may be thousands of years old.
Katey Walter Anthony, a biogeochemistry at the University of Alaska, Fairbanks report – These craters are recently discovered by scientists but it doesn’t mean they are new. Katey studies methane release from permafrost.
The Melting Siberia:-
There’s no doubt, the permafrost of the Siberian tundra is melting. Permafrost locks up organic materials like dead plants (Well, it can be the corpses of the mammoths) also protect them from rotting. And when the permafrost melts, all those organic materials begin to decompose. This decomposition releases carbon dioxide, methane as well as the nitrous oxide, along with all potent greenhouse gasses.
Oh! And with that, the Climate scientists agree that the permafrost thaws will amplify the effects of greenhouse gasses which are released by the human activities, and it could worsen the amount of warming the planet experiences.
And the noticeable thing is this methane through the decomposition of ancient organic material shouldn’t be confused with the methane hydrates, which are ice lattices that contain methane trapped inside. Thawing methane hydrates are another context for the climate because their melt could also release more of that greenhouse gas into the climate.
Walter Anthony said- More effective collapse features, known as the thermokarsts. It happens when the frozen-solid soil melts and it can collapse in many ways, like creating landslides, lakes, pits, even underground tunnels.
Well, it’s not sure what the real reason behind the Siberia Crater is, but one thing is sure that those huge craters are really eye catching and matter of concern for all of us as well.
