Live Wilderness Adventure - Chapter 684 Eternal night is coming

Burn! !

The audience widened their eyes and exclaimed in surprise.

Can soil also burn?

"Of course, even the combustion effect is very good. You can simply understand it as soil-like charcoal. It also has another name, that is, peat and peat. It is the coal with the lowest degree of coalification."

This metaphor made everyone instantly understand the burning power of peat soil.

It turned out to be coal!

The charcoal in his hand ignited a spark. Bi Fang blew it slowly, and a small flame quickly rose on the tinder. Seeing this, he did not rush into the peat, but grabbed a handful of loose peat soil.

"When the organic matter content in the clay exceeds 10% but less than 60%, it is called peat soil, and only more than 60% can become peat. combustion."

"This is a kind of soil formed by the accumulation of incompletely decomposed plant remains in a humid and anoxic environment. The appearance is usually dark gray or black, with a fishy odor, and incompletely decomposed plant structures can be seen. And it is easy to disintegrate, and there are plant residues floating in the water, and the phenomenon of drying shrinkage is obvious."

The audience got closer, and sure enough, they found tissue similar to plant roots in the soil.

"In addition to the characteristics of peat soil, peat also has the properties of loose structure, light soil, and dull and dull soil."

With so many properties, it is not difficult to identify the peat soil, plus the faint fishy smell, Bi Fang recognized it at a glance.

[However, is there such a thing in the North Pole? 】

[There are not many plants in the Arctic, so there are so many plant remains? 】

The audience was a little strange, because listening to Bi Fang's meaning, there should be more of this thing in the tropical rain forest, where can there be countless plant remains.

"So you didn't hear the preconditions at all, right?" Bi Fang laughed, "It's completely different from what you guessed, the tropical rainforest or something, the microorganisms are too developed to leave plant debris basically, so seven percent of the world's Ten peat bogs are actually located in the Arctic, most of them are in high latitudes, and there are more peat soils in low latitudes, I think..."

"Oh, the Indonesian forests are full of peat bogs."

"However, we must be careful when using peat, and we must take precautions. Because peat soil is easy to burn, and its properties are similar to coal, you can imagine the scene of starting a fire on a coal pile."

[Fuck, is it so scary? 】

【To die or to die】

[Lao Fang is really brave]

The audience sucked in a breath of cold air, which was too scary.

"Haha, it's actually not that exaggerated. After all, the degree of coalification is very low, and it needs to be dried. We are also surrounded by snow and ice. It's fine to be careful. I just want you to understand that it does have certain dangers. ."

As said, Bi Fang did not choose to set fire in the remaining mud pit, but put a lot of snow on the side, then filled it with ordinary frozen soil, made it into a concave shape, and threw the peat soil and flames into it, almost nothing. After a long time, the flames were roaring, emitting amazing heat, and the cave was warmed up all at once.

Taking off his coat, Bi Fang raised his head and looked at the musk ox above his head. He felt that this seemed to be a different kind of smoke, but the smoke was a bit loud.

"no."

Bi Fang picked up the shovel and dug to the side. He had to divert the fire. He didn't want his musk beef to taste unpleasant and dry.

"In many places, when there is a forest fire in the summer, there is a good chance that it will spread to the peat bogs where the forest grows. Not only will they increase the fire, but they are also potential climate bombs."

“When the peat bogs burn, they release carbon dioxide that has been stored for several geological ages. When the soil begins to burn, it releases a choking smoke that can only be stopped with the help of a bulldozer. Fires can last for months or days. years, so the loss of peat is huge.”

"The carbon content in the atmosphere is 7,500 tons, and there may be 250 billion to 450 billion tons of carbon in the peat bogs in the Arctic. Once fully released, the carbon content in the atmosphere will increase by 50%."

Bi Fang made an alarmist conclusion.

"I don't know if you still remember the huge wildfires that broke out in the jungles of Australia, Australia and the ugly country of California the year before last. As a result, the earth lost hundreds of millions of wild animals, and many species entered an endangered state. In fact, there were also many outbreaks in the Arctic at that time. Wildfires, but the coverage is not high."

"The wildfire smoke rising from the ground in the Arctic at that time created a huge plume of smoke in the stratosphere, which can be clearly seen on satellites."

"It wasn't until the next day, after months of cold weather, that the bushfires on the surface of the Arctic were all extinguished, but the fires below were still burning."

"Even near the village of Saidi, about 400 kilometers northeast of Yakutsk in the Arctic, the underground fire continued to burn at a temperature of -50°C. It burned from Udarnik to Saidi, and all important resources were burned."

The audience was dumbfounded, burned for a year?

Is this too exaggerated?

"Peat fires are different from bushfires that are usually seen. Because they are hidden underground and burn quietly, it is extremely difficult to put out. Even if there is heavy snow on the ground, the peat fires still burn underground."

"It burns under the ground, no flames are visible, and there is only a small amount of smoke, so unless satellites detect temperature anomalies, it will be difficult to detect."

"Especially, this kind of fire can burn all the way to the upper part of the mineral layer and groundwater. Although the speed of spread is slow, only 4-5 meters per hour, it can burn dozens of meters in a day and night, but it is not easy to Save, burn for days, months or longer."

"Underground fires that occur in autumn can usually overwinter and continue to burn until the spring of the following year, so they are also called overwintering fires."

The audience was once again shocked by the power of nature, and it was the first time they heard that there was a flame that would burn underground.

[Speaking of which, what would happen if the underground fire spreads all the way to the coal]

[Isn't that a direct explosion? 】

During the audience's discussion, Bi Fang began to dig a hole in the ground, preparing to build a greenhouse next to it, and to let out the smoke as much as possible.

With the efforts of one person and three dogs, the progress was fast, and it was completely dug out in one afternoon.

Bi Fang also immediately transferred the flame. Although the possibility of artificially igniting the charcoal layer is extremely low, there is still a lot of snow here, and when the temperature is high, it will melt into water and extinguish the flame, but still be careful.

As a public figure, Bi Fang also tries his best to convey the correct knowledge and methods to the audience.

Under the condition of fire and food, Bi Fang and Sansha squatted for three days in a row, and the blizzard and sandstorm outside finally showed signs of stopping.

And the eternal night will come in less than five days.
