Russia may lose 30% of permafrost by 2050

Permafrost or soil that is permanently frozen, covers about 63% of Russia
Russian scientists dig up food products buried in the Arctic permafrost in the Taymir peninsula. Russia has warned that vast permafrost areas may shrink by a third by the middle of the century due to global warming, endangering infrastructure in the Arctic zone.

Russia's vast permafrost areas may shrink by a third by the middle of the century due to global warming, endangering infrastructure in the Arctic zone, an emergencies ministry official said Friday.

"In the next 25 to 30 years, the area of permafrost in Russia may shrink by 10-18 percent," the head of the ministry's disaster monitoring department Andrei Bolov told the RIA Novosti news agency.

"By the middle of the century, it can shrink by 15-30 percent, and the boundary of the permafrost may shift to the north-east by 150-200 kilometres," he said.

The temperature of the zones of frozen soil in oil and gas-rich western Siberia territories will rise by up to two degrees Celsius to just three or four degrees below zero, he predicted.

Permafrost, or soil that is permanently frozen, covers about 63 percent of Russia, but has been greatly affected by in recent decades.

Continued thawing of permafrost threatens to destabilise transportation, building, and energy extraction infrastructure in Russia's colder regions.

"The negative impact of permafrost degradation on all above-ground is clear," Bolov added.

Scientists have said that permafrost thawing will set off another problem because the process will release massive amounts of greenhouse gas methane currently trapped in the .

Will this also open up millions of acres to farming and ranching?

Probably. It'll probably "open up" even more land for... well whatever you can do with a desert.

It will also release a lot of water that is presently frozen, watering that "desert."

Did anyone else catch the picture caption above? It reads:
Russian scientists dig up food products buried in the Arctic permafrost in the Taymir peninsula.

Now, how did the food products get into the permafrost???

Wait, you mean the permafrost wasn't there when the food products ended up there?

Well, then, if that is the case then are we not merely returning to what was back when the food products ended up buried there?

...They got there by digging, just like the scientists. lol

Possibly. The article does not tell us. I did have to ask, though, because various things have been found in the permafrost of Greenland that got there via agriculture, prior to the ground becoming permafrost there.
