Chapter 687 Eternal Night is Coming
combustion! ! !

The audience's eyes widened and they all exclaimed.

Can soil burn?

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

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

It turned out to be coal!
The charcoal in his hand ignited sparks, Bi Fang blew slowly, and a small flame quickly sprang up on the tinder. Seeing this, he was not in a hurry to put in the peat, but grabbed a handful of loose peat soil.

"When the organic matter content in the clay is more than 10% but less than 60%, it is called peaty soil, and only more than 60% can become peat. Most of the calorific value of this soil is 9.50-15.0 megajoules per kilogram, which is very easy. combustion."

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

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

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

With so many properties, it is not difficult to identify peat soil, coupled with a 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 surprised, because from what Bi Fang said, there should be a lot of these things in the tropical rainforest, where there are countless plant remains.

"So you didn't hear the prerequisites at all, did you?" Bi Fang laughed, "It's completely different from what you guessed. In tropical rainforests, microorganisms are too developed to leave plant debris, so 70.00% of the world's peat The swamps are actually located in the Arctic zone, most of them are in high latitudes, and there are more peat soils in low latitudes, I think about it.”

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

"However, we must be careful when using peat, and we must take good care of it. Because peat soil is easy to burn and has properties similar to coal, you can imagine yourself lighting a fire on a pile of coal. "

[Fuck, is it so scary? 】

【Die or Die】

【Old Fang is really courageous】

The audience gasped, it 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 surrounded by ice and snow. It is normal to be careful. I just want you to understand that it is indeed dangerous. .”

As said, Bi Fang did not choose to light the fire in the remaining mud pit, but put a lot of snow next to it, and then filled it with ordinary frozen soil to make a concave shape, and threw peat soil and flames into it, almost without fire. It didn't take long for the flames to burn blazingly, emitting astonishing heat, and warming up the burrow all of a sudden.

After taking off his coat, Bi Fang looked up at the musk ox above his head, and felt that this was a different kind of smoke, but the smoke was a bit heavy.

"No."

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

"In many places, when forest fires start in the summer, they have the potential to spread over forested peat bogs. Not only do they intensify the fires, but they are a potential climate bomb."

"When a peat bog burns, it releases carbon dioxide that has been stored for several geological epochs. When the soil starts to burn, it emits a choking smoke that can only be stopped with the help of a bulldozer. Fires can last for months or years. years, so the loss of peat is extremely large.”

"The carbon content in the atmosphere is 7500 billion tons, and there may be 2500 billion to 4500 billion tons of carbon in the peat bogs in the Arctic zone. Once fully released, it will increase the carbon content in the atmosphere by 50%."

Bi Fang said an alarmist conclusion.

"I don't know if you still remember the huge wildfires that broke out in the jungles of Australia and California the year before last, and the earth lost hundreds of millions of wild animals, and many species were endangered. In fact, there were also many wildfires in the Arctic Bushfires, just underreported."

"Smoke from wildfires rising from the ground in the Arctic at that time created huge plumes in the stratosphere that were clearly visible on satellites."

"It wasn't until the following year, after months of cold weather, that the surface bushfires in the Arctic were completely extinguished, but the subsurface fires continued to burn."

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

The audience was dumbfounded, burning for a year?
This is too exaggerated, right?
"The peat fire is different from the bush fires we usually see. Because it burns quietly underground, it is extremely difficult to extinguish. Even if there is heavy snow on the ground, the peat fire still burns underground."

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

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

"Underground fires that occur in autumn can usually survive the winter and continue to burn until the next spring, 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 still a fire that would burn underground.

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

[Didn't it just blow up? 】

Bi Fang began to dig a hole horizontally amidst the audience's discussion, preparing to build a greenhouse next to it, and to release the smoke as much as possible.

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

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

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

With the flames and food available, Bi Fang and Sansha squatted for three days in a row, and the blizzard and sandstorm outside finally showed signs of stopping.

As for Yong Ye, there are less than five days to come.
