Yang Xiao personally took Gong Yu, Huang Wen, Qin Yu and others out of the building and walked around Shashi City.
As everyone walked along Wuyi Road, the main road in Shashi, everyone felt that the snow under their feet had become loose, and a hole appeared when they stepped on it.
After a year of freezing, the snow had originally become hardened, but now when you step on it, the top layer of snow has loosened.
Everyone began to get excited inside.
"Boss, spring is really here?"
"I just hope that spring will come soon. I really want to wear a skirt." Qin Yu said with a smile.
"You can wear it now. I won't freeze you to death." Deng Xiao reached out and poked Qin Yu.
Everyone talked and laughed all the way and walked for more than half an hour to the Xianghe Bridge.
On the iron railings on both sides of the bridge, Yang Xiao touched the snow on it with his hands. It was indeed a little wet. Although it had not completely turned into water, the change was already obvious.
After iron railings are exposed to sunlight, the temperature rises quickly and the snow on them melts easily.
In the past, because the temperature of the entire earth was very low, although the iron railings were exposed to sunlight, the snow on them never melted.
"Now it seems that the temperature of the entire earth has risen, and the sun in the sky seems to be stronger than before."
Yang Xiao looked at the sun in the sky, then stood on the bridge and looked into the distance.
The world in front of me is still a vast expanse of white.
The Xiang River has basically been dug up, and there are ice fish left everywhere on the ice on the river. There is really no end to these fish.
Gong Yu suddenly said:
"If the ice and snow melt, we may temporarily have a phase of food shortages."
Yang Xiao was stunned and asked:
"Why?"
"Think about it, what is our main food now? It's ice fish, and some grains stored before the end of the world. But after a year or so, those grains are basically used up."
"But now we still have mountains of ice fish. There are so many ice fish in Xingyue Lake that we can't finish them all in a few years," Huang Wen said.
"It does seem like there are a lot of them now, but once the ice and snow melt, you will find that there are fewer of these ice fish overnight."
Gong Yu smiled.
Yang Xiao was stunned, patted Gong Yu on the shoulder and said:
"As expected, he is a top student at Shanghai University of Finance and Economics. His thinking is advanced."
Huang Wen, Qin Yu and others still didn't understand and looked at Yang Xiao.
"Think about it, why can ice fish be preserved today and not rot?"
"The weather is so cold now, and there is ice and snow everywhere. The earth is like a big refrigerator, so it is naturally easy to preserve. Is this surprising to you?"
"However, once the weather gets warmer, the earth heats up, and the ice and snow melt, these ice fish will quickly rot within a few days and become inedible."
Gong Yu smiled.
After everyone heard this, they immediately woke up.
"What should we do?"
"It has been a cold winter for a year. There is a lot of snow on the earth, which cannot be melted in a day. The cold temperature can still last for about a month or two. This month or two is the time left for us.
I remember watching a documentary about the life of the people in Iceland before the end of the world. They would hang fish salvaged from the sea directly outside and use the cold air to dry them, so that the food could be preserved for a long time. "
Yang Xiao said as he led everyone to continue walking forward. After crossing the bridge, there was Jinwan Town. After passing Jinwan Town, they entered Xianan University.
Yang Xiao has not been to Xia Nan University for a long time. There are currently less than 200 people stationed at Xia Nan University, all of whom are ordinary genetic evolvers.
Yang Xiao chatted with the people stationed here. They said that about ten days ago, the snow on the ground showed signs of loosening, but no one took this situation seriously.
Through the teleportation array, Yang Xiao came to Xiangnan University. There are still 800 people living in the cave dwellings of Xiangnan University, some of them are old people from the past, and some of them were transferred from the nearby Star City.
The floor heating and air conditioning in Star City has long been stopped due to the lack of diesel power generation. However, the cave dwelling at Shonan University is very nice. It is surrounded by mountains and forests, and there is a lot of wood that can be cut down for heating, so some people come to live here.
Everyone felt very emotional to return to their alma mater. Huang Wen, Qin Yu, Deng Xiao and others also went skating on the playground, but because the snow on the surface began to loosen, the skating felt not as smooth as before.
When returning, Yang Xiao came to Xia'nan University and went directly to Xianghe River through the path of Xia'nan University.
The ice in the Xiang River has been turned over, and there are potholes everywhere. The changes in the ice here are not particularly obvious.
Gong Yu on the side said:
"Ice is different from snow. Ice reflects the sun's rays and absorbs less heat. In addition, the entire river bed is covered with ice and the volume is large. No changes can be seen for the time being. Snow on land is It’s different, especially for snow attached to buildings, because buildings tend to absorb the sun’s heat and then conduct it to the snow above, which melts faster.”
Yang Xiao smiled and said:
"You are really a top student."
Gong Yu said: "This is all junior high school physics knowledge, okay?"
Yang Xiao could only be speechless.
Two days later, Charlotte and others gathered together and reported what they saw. It was true that the snow in various places began to loosen, and some places even began to melt. However, there was no ice in the entire Xingyue Lake for the time being. Variety.
Yang Xiao said:
"Based on the situation in the past two days, we can temporarily conclude a basic fact, that is, the temperature of the earth is slowly rising. Although it is still cold at night and very cold during the day, there are already signs of thawing. Once the snow accumulates, Melting, we will encounter some new situations,
After the temperature rises, ice fish becomes perishable and cannot be preserved. Once the main food source of ice fish is lost, more than 40,000 people in the two cities will face starvation. Therefore, from now on, except for those who dig ice fish, , the rest of the people must be mobilized, and all the ice fish that were previously piled in the rivers and Xingyue Lake must be transported to the shore, the fish maws will be broken open, the internal organs will be dug out, and then hung up to dry.
This work is very important and is related to our food security in the future. After everyone returns, everyone must be mobilized to pay attention to this matter, as well as the stored food. Once the weather warms up, many places will become humid, so be careful to prevent moisture. . "
"A large amount of snow melts, and the ice water from the upper reaches slowly flows down. When it reaches our place, floods will definitely occur. Our Shashi City is located in the middle and lower reaches of the Xiang River. Fortunately, our current population is relatively small, so everyone During this period, we must pay attention to find a safe place to live, and wait until the floods come before everyone can move in to temporarily avoid the floods,”
"Once the floods occur, it will take at least a month based on the current situation. Within this month or so, will my food safety be guaranteed?"
