GLOBAL WARMING AND METHANE BUBBLES from the permafrost of Siberia

GLOBAL WARMING AND METHANE BUBBLES  from the permafrost of Siberia

Methane bubbles escaping from the permafrost of Siberia created a 50-meter deep pit

That is Siberia in the snow and ice. Underground methane gas escaped from the cracks in the earth's crust, but was covered by the frozen ground layer, forming a larger and larger bubble (unclear how old it is). Now, the bubble burst, creating a crater up to 50 meters deep.

According to the Siberian Times report, when the scientists went to investigate, the television crew in a helicopter first discovered the pit. The flying ice and rocks are hundreds of meters away from the big hole.

The methane gas has long since disappeared, leaving only huge voids.

It is not yet clear how the crater formed or whether climate change played a role, but after a continuous unusually warm summer, a similar weird phenomenon was also found on the Yamal Peninsula in northwestern Russia in 2014 (same order) People are upset).

In fact, this is at least the 17th "big hole" discovered in the area so far, and the largest of its kind in recent years.

The huge hole is believed to be caused by the sudden collapse of a hill or the expansion of the tundra.

Due to man-made climate change, the permafrost in the Arctic is rapidly disappearing, but few studies have investigated this change.

Methane, as a greenhouse gas is 84 times more efficient than carbon dioxide therefore, a large release of this gas may trigger a vicious feedback loop and make the current global climate crisis more worst.

By analyzing historical images dating back to the 1970s, a 2017 study found that the number of sinkholes in Siberia has increased in recent years, indicating that the melting of permafrost has at least partially caused such collapses, as well as the Arctic methane reservoirs. freed.

In the same year, another study found 7,000 natural gas reservoirs under the Yamal Peninsula.

However, we do not know whether these air pockets are new. Permafrost occupies about two-thirds of Russia's territory, mostly in the most remote and inaccessible areas in the world, and the agencies responsible for surveying are seriously understaffed.

In addition to spewing out a lot of methane one day, scientists are also worried that the melting permafrost will release ancient microorganisms that we don't know about.

In fact, this may have already happened. In 2016, an anthrax outbreak killed a 12-year-old boy. The cause can be traced back to the melting of permafrost, which leaked the old virus into the local hydrological environment.

This is not the only danger. Just this year, the melting of permafrost caused the most serious fuel leak in Arctic history. Considering the structure and location of more fuel pipelines, scientists are worried, especially the Yamal Peninsula is in this danger.

Even if it does not release the virus or trigger an oil spill, a huge crack that suddenly appears on the ground is usually not a good sign.
