Scientists sound the alarm: methane from Siberian subsoil can bury all of humanity

It is known that Siberia is a rich storehouse of natural resources, filled with oil, gas, and rare earth metals. However, in addition to the undoubted benefits, the Siberian subsoil is fraught with a real threat, both for the region and for the planet as a whole.

Eurasia filter

The planetary role of Siberia can hardly be overestimated. This land area, still poorly developed by man, provides not only the most valuable raw materials, but also contributes to the maintenance of the climatic and ecological balance on the planet. It depends on Siberia what kind of air will breathe in Europe, what crops will be harvested in China and how the climate on Earth will change.

Not everyone probably knows that Siberia on the scale of Eurasia performs the function of a giant filter. Western winds not only bring here the moisture of the Atlantic, but also the polluted air produced in European countries. Siberian forests, swamps and glaciers, accumulating harmful substances, do not allow them to go with streams into the waters of the oceans.

Another important task of Siberia is the absorption of carbon dioxide from the atmosphere. The world media has repeatedly published the figure – 180 million tons per year. Siberian forests and swamps, along with the Amazon selva, are the largest ecosystems that slow down the global warming process, so any negative impact on this region threatens the planet with the most serious cataclysms.

Natural bomb

Fires and uncontrolled deforestation reduce the ability of Siberia to act as an atmospheric filter. However, human activity will only exacerbate the negative processes that have been ripening in the Siberian bowels for more than a decade. Back in the second half of the 20th century, Japanese scientists recorded large emissions of gas hydrates in the West Siberian Lowland. At first they thought that this was the result of human economic activity, but it turned out that the swamps were to blame, releasing the product of decay – methane – into the air.

With the onset of the 21st century, methane emissions have only increased. The main role in this is played by the active melting of glaciers, which every year releases more and more volumes of poisonous gases that have rested underground for millennia. Scientists are sure: this is how global warming makes itself felt, which in turn is accelerating due to the accumulation of methane hydrate in the air – the most dangerous of all gases in the bowels of the earth. It turns out a vicious circle.

Until 2007, the influence of methane on the development of the greenhouse effect was not so obvious until the international commission dealing with the problems of climate change published its report. According to experts, the thawing Siberian swamps alone emit over 50 billion tons of harmful gases a year. Climatologists warn that a methane leak will inevitably lead to an increase in the average annual temperatures on the planet.

The latest research by Russian scientists showed that in Siberia there are up to 7 thousand underground methane bubbles that can burst at any moment. In their opinion, methane located under the water layer is much more sensitive to temperature increases than methane hidden under the permafrost layer. After all, some parts of the Siberian tundra do not thaw even in summer. However, in the coming decades, the situation may radically change. According to research, over the past 5 years, the temperature in Eastern Siberia has already increased by two degrees Celsius.

Not only methane bubbles are a time bomb, but also empty wells, through which gas and oil have been pumped out of the Siberian bowels for decades. According to Nikolai Lashchinsky, Chief Researcher of the Laboratory of Geosystem Research of the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences, thoughtless drilling led to the formation of huge voids underground. If these cavities once “collapse”, they will cause a seismic wave of unpredictable power. This, according to Lashchinsky, can happen both in 10 years and tomorrow.

Drilling wells, deforestation, melting glaciers – all this is gradually leading to the desertification of Siberia. Scientists estimate that over the past 200 years, the carbon dioxide content in the air has increased by about 40%. If we disrupt the ecosystem of Siberia, then we are in danger of a catastrophe on a planetary scale. In some places, abnormal droughts will begin, in others, unprecedented frosts will come.

Hot ocean

Not only poisonous gases and vast cavities that hide the Siberian subsoil can conceal a threat to the region. Geochemists from Russia, Germany and France discovered the ocean of the Archean period (about 2.7 billion years old) at a depth of 400-600 meters. The results of this work were published in the journal Nature. This primeval ocean, whose temperature in places reaches 150 degrees Celsius, hides an inexhaustible source of energy.

According to the Russian geologist Vladimir Larin, all the earth’s interior is filled with geothermal water. Moreover, the volume of the underground ocean is comparable to that of the world – about 1.3 billion cubic kilometers. If the terrestrial ocean receives heat from the sun, then the underground is fed by the energy of the earth’s core. This is still a completely unexplored world,
