Arctic, methane bubbles under permafrost. “The ice melts and releases gas”
It happens more and more often that with the melting of ice craters emerge (in English, sink) formed under the permafrost, upon which some of the most imaginative hypotheses and legends have flourished for years, from the fall of meteorites to the landing of UFOs. Scientists actually believe that the chasms are the result of the explosion of methane bubbles trapped in the ice that, once melted, reveals the deep openings in the ground. A phenomenon known for some time, but still largely shrouded in mystery, which scholars believe may be favored by rising temperatures. Experts are also concerned about the release of gas into the atmosphere that adds to greenhouse gas emissions, thus contributing to global warming. But it is not known for sure how these craters form or how many there are, he explained to CNN. Evgeny chuvilin, a permafrost expert from the Skolkovo Institute of Science and Technology. Also because they are often identified by chance, but not always reported by the shepherds who lead the flocks to graze after the winter period. The holes then fill with water and become ponds in one or two years. According to Chuvilin “the frost that precedes a crater tends to form quite quickly and therefore it is difficult to observe the phenomenon in progress. Almost all the craters were discovered when the abyss had already opened.”
