New research answers remaining questions about the explosive Tindra in Siberia

Are you looking for another reason for climate change? no? Well, this is one anyway. The high global temperatures cause Parts of Siberian tundra explodes automatically.

Scientists have been studying this strange phenomenon since 2014, when a mysterious hole appeared with a depth of 165 feet (50 meters) in the Yamal Peninsula in the northwest of Siberia. Since then, specify More than ten similar pits On the Yamal Peninsula and good and Linking its formation to climate changeBut the main questions remain. Now, a new study can provide some long -awaited answers.

The secret of sudden holes for Siberia

Monday research in the magazine Overall ecology It depends on the previous work Find The unique geology in the region – accepted with increasing temperatures – raises sudden explosions of methane gas from the bottom of the frost soil. As the soil of the frosty soil, the water leaks into sub -surface pockets from the salty water called Crypegs, and this process began.

On the Yamal Peninsula, Crypegs is about 3 feet (1 meters) and sits up to 165 feet (50 meters) under the ground. Under it lies another layer full of crystallized methane. While Milite leaks water in Crypegs, it builds pressure and creates cracks in the soil that is heading towards the surface. This reflects the pressure gradient, causing a sudden decrease in pressure on a depth that damages methane and – boams!

It seems reasonable, right? But the results did not explain the reason for the occurrence of the explosions only in Siberia, though The rest of the Arctic is also heated quickly. In fact, none of the current models of drilling were able,He said The New York Times.

Cracking the case: Why Siberia?

To reach the bottom of this, he and his colleagues reviewed these current models in a critical way. The team concluded that the drilling is very large so that it cannot be explained by tearing small gas pockets alone. They built their computer models to gain a more accurate understanding of their formation, and they found that it might be linked to cracking in the area.

The gas and heat that rises through the malfunctions from the deep ground can become trapped in a cavity sealed under the frost soil, as its models indicate. It also melts frosty soil, this seal weakens. Meanwhile, the pressure inside the cavity is built as the higher temperatures are launching a gas besieged under the ice. This, along with a highly compressed gas from deep errors below, can make the entire system go kablivey.

Consequently, the deep heat and gas that rises from the bottom of the soil is the main cause of this drilling, according to Huifang and its colleagues. The heating in the atmosphere still plays a role, albeit indirectly. It speeds up the warming of the ice melting, weakening the soil and helping the lakes and new rivers. This paves the stage for gas and heat to travel through defects and operate the explosions.

“With heating and weakness in the surface ice (follow -up), more explosions are likely,” Hevang told New York Foundation. He said he would like to notice how this gas drilling turns into lakes over time to see if they resemble other lakes in the region. This can help explain the origin of some of the round lakes that indicate the scenery of the DAPLE SIBERIA.
