Giant crater in Siberia continues to increase


There is a crater in Siberia that is increasing rapidly, scientists believe that this phenomenon is due to climate change.
Near the Yana River basin in Siberia, in an area of frozen soil, there is an expanding crater, named Batagaika. Its size is generating some concern, one kilometer in length and 86 meters in depth, according to the BBC, are both increasing with the passage of time.

If on the one hand the local people do not want to get close, on the other, scientists consider the phenomenon a fundamental aid and an excellent opportunity to know better the evolution of the climate. In a preliminary analysis of this phenomenon, published this month in Quaternary Research, scientists who have studied this crater ensure that by observing the various layers of soil that make it up, one can understand another phenomenon: that of climate change Which experts say is the cause of the huge hole’s growth).

The various layers of the crater allow the “continuous recording of geological history, which is rather unusual” to find, explained Julian Murton, a scientist at the University of Sussex in the United Kingdom, quoted by the BBC. Experts believe that the study of the crater reveals 200 thousand years of the history of the climate, only by analyzing its various layers.

Frank Günther of the Alfred Wegener Institute in Germany has been monitoring the site along with his team. They do it for more than a decade, through satellite imagery. The main objective is to keep up with the changes that are taking place and to make constant measurements. At the end of last year’s meeting of geologists, some conclusions were presented, including the scale of the problem: in the last 10 years, this detailed analysis allowed us to verify that the crater grew at a high speed, that is, about 10 meters per year.

“The crater is growing steadily and that means it is getting deeper with each passing year”, he said in a statement to the BBC.

Although the experts have a valuable element of climate studies, they warn of the risks that the crater brings to the same phenomenon that helps to understand better: climate change. This is because the ice blocks that are now being exposed and dating back to the ice age, have a lot of stored organic matter, namely, carbon.

Thus, according to Günther, the amount of carbon stored in the ice is the same as that in the atmosphere, as the carbon is released, it is consumed by microbes that in turn produce methane and carbon dioxide that are released into the atmosphere. Atmosphere, thereby accelerating global warming.

Experts call it “positive feedback: heating that speeds up heating”, explained Frank Günther, the same scientist also assures that there are no infrastructures that can solve the situation, so they believe the future of Siberia is compromised.
