Secrets revealed under the 'eternal time bomb' in Siberia

Mummies, mammoth tusks, giant viruses are among the artifacts that could be uncovered if Siberia's permafrost melts.

The Siberian permafrost is like a natural refrigerator that has preserved everything buried inside for hundreds of thousands of years, according to Wired. But global warming is causing this refrigerator to go into defrost mode. "Permafrost is a time bomb," said Robert Spencer, an environmental scientist at the University of Florida. As it thaws, the ice could reveal things it has kept hidden for centuries.

Bacteria

An anthrax outbreak in western Siberia 75 years ago killed many reindeer herds. Warmer weather thawed the decades-old frozen carcasses of some of the infected reindeer in July, spreading the anthrax bacteria that infected 23 people and killed one.

Carbon

The remains of ancient grasses, fungi, and animals buried in the ice contain a total of 1,500 billion tons of carbon. Microbes and bacteria eat the thick layer, releasing carbon dioxide that warms the atmosphere. Warming in turn melts the ice. The carbon escapes from the permafrost, repeating the cycle over and over again.

Methane gas

In 2014, scientists began noticing large craters appearing along the Yamal Peninsula in Russia’s remote region. The most likely explanation is that the ground is getting warmer, causing the ice to melt, which makes the ground wetter. Bacteria produce more methane, which causes explosions that cause the ground to collapse into craters.

In 1993, a Russian researcher found the remarkably well-preserved 2,500-year-old body of an ancient princess covered in spiral tattoos, buried with figurines, spice jars, and six horses. Archaeologists believe that the woman was of noble descent in life, unlike the bodies in the usual burial site.

Climate change causes rapid soil erosion, making ancient bones more easily exposed.

Virus

Over the past two years, French microbiologists have discovered two giant ancient viruses buried deep in the Siberian permafrost. These viruses can still infect other organisms, such as amoebas. However, the researchers warn that there are far more terrifying viruses lurking in the thick ice.
