Back on June 12, 2146:

"No, it's not true, how can this be ......", Pan Yueming kept convincing himself that this was an illusion in his heart, and he bit his right index finger vigorously until a few drops of bright red blood oozed out, and he confirmed that he was awake again.

Seeing this scene on the computer screen for several days in a row, I have to believe that all this is happening in reality, and now that it is the sixth day, will it continue like this, and if it is so, how will the world change?

Pan Yueming slowly opened the drawer and took out the slightly old notepad as usual. The label in the upper right corner of the A5 notebook reads in black carbon pen: [Year 2146].

He quickly flipped to the nearest blank page and scribbled:

Date: June 12, 2146, Time: 4:22:12

Temperature: -18 degrees Celsius, wind direction: southwest wind level 5

Recorded by: Pan Yueming

1. The signal of the Penguin observation point is lost.

2. The elevation of the Red Star ice floe today is 28.46m.

3. The elevation of the top of the Seal iceberg is 3228.34m, which is 55.8m lower than yesterday.

……

Closing the notepad, Pan Yueming dialed the internal phone in the dormitory.

"So early, master", before Pan Yueming could speak, the lazy voice of assistant Liu Yiyang came from the other end of the phone.

"Xiao Liu, it's time to get up, let's go out", Pan Yueming responded.

"It's about three minutes", Liu Yiyang seemed to be much more sober.

Three minutes later, just right, Liu Yiyang, dressed in a gray cold-proof suit, appeared at the entrance of the gate of the inspection station.

"Master, where is this going?"

"On the way, I said, get on the sleigh first", Pan Yueming quickly walked out of the inspection station and threw Liu Yiyang a sleigh key.

The two changed into ice boots, put on their helmets, jumped on the air cushion sled, and quickly drove out of the Antarctic research station in Country C, heading straight for the Seal Glacier, leaving two snow mist rising from the ice.

"Where are we going, so anxious to get out?" , Liu Yiyang turned his head and asked.

"It's been six days, we've set up several observation points, and the rate of snow and ice melting is increasing exponentially every day, and what I feared is going to happen.

We are now going to the Seal Glacier, the elevation data just now is 55.8 meters lower than yesterday, it is definitely not normal for such a large area of glacier to melt so much in one day, now go to the location of the observation point to see if there is a problem with the signal source set", Pan Yueming replied.

God bless, I hope it is not really so dissolved, Pan Yueming secretly prayed in his heart.

The observatory is only more than 40 kilometers away from the top of the glacier slope of the Seal, and it would take less than an hour for this air-cushion sled to arrive in normal times, but today's Pan Yueming drove very carefully, and the average speed was only more than 20 kilometers per hour at most.

"Master, how much impact will the 55.8-meter descent of the Seal glacier have?" , Liu Yiyang asked.

"Let's put it this way, the world's largest glaciers are the Antarctic and Greenland ice sheets, which store more than 90 percent of the world's fresh water, including 70 percent in Antarctica.

The Seal observation site we are going to is the source that was planted when our country successfully reached the summit in January 2005.

The entire ice sheet of Antarctica covers an area of nearly 14 million square kilometers, and such a large area melts 55.8 meters in a day, how many cubic meters of fresh water flow into the sea? ”。

"Oh my God, it's not an astronomical number, but it's nothing for the global oceans!" , Liu Yiyang whispered.

"It's really nothing, and at this rate, the entire Antarctic ice sheet will disappear in nine months, isn't that nothing? Do you know what happens when the two ice sheets of Antarctica and Greenland melt completely? ”。

Pan Yueming paused at this point, and then said:

"That's dumping more than 24 million cubic kilometers of fresh water into the ocean, and the global sea level will rise by nearly 60 meters, which will bring about a sharp change in global temperature, and various disasters such as tsunamis, earthquakes, and volcanoes will rage around the world.

As the glaciers melt further, there will be an irreversible vicious circle and the Earth will enter a second ice age, which is simply terrifying, and I think that if this is the case, we will not have many days left! Pan Yueming accentuated his tone, he was obviously a little dissatisfied with the ignorance of this new assistant.

"Be careful, ah......h

Before Liu Yiyang could fully scream, the air cushion sled had slammed into an ice wall that suddenly appeared, and the two forks of the sled's head had completely pierced into the ice wall, and Liu Yiyang was thrown more than 20 meters away by inertia, half lying on the ice pier and fainting.

On the other side, Pan Yueming's helmet hit a hemispherical pit on the ice wall, and he was violently bounced off the ice by the ice wall and did not wake up, and the entire tempered glass mask was shattered into a spider web, as if the windshield of a car had been hit by a heavy object.

His face could no longer be seen through the mask, and the glass slag was all stuck to the laminate, but fortunately, the quality of the mask was really good, and it should not have hurt him.

I don't know how long it took, the roar of the sled engine on the ice on the back became weaker and weaker, it should be that the fuel was running out, and Liu Yiyang, who was not far away, slowly woke up because he was not seriously injured.

Trying to move his lower limbs, Liu Yiyang found that there was nothing unusual in his body, sat up with his hands supported, took off his helmet and put it beside him, and slowly recalled the scene of the accident.

"Oh no, how's the master?" , Liu Yiyang turned his head and quickly looked around for the trace of the master, where did she know that she was thrown by the damn physical inertia to lie on the ice pier more than ten meters high.

Gradually, as she slowly regained her sense, she heard the roar of the sled engine in her ears, one after another.

Liu Yiyang stood up, the Antarctic in June was in the middle of the half-year-long polar night, the surroundings were pitch black, and all she could see was the twinkling stars in the sky.

The light reflected by the headlights of the sled through the ice wall was very soft, and finally she found herself standing on the ice pier more than ten meters high, due to the angle, she did not see the sled, but saw Pan Yueming who fell to the ground. "Master, how are you?" , Liu Yiyang called out loudly and walked towards the edge of the ice pier.

This is in normal times, more than ten meters high for a twenty-two-year-old young woman would not dare to jump down anyway, but at this time Liu Yiyang didn't care much, she squatted down slowly with her back to the edge of the ice pier, while taking off the leather gloves, while climbing the ice edge with both hands and slowly lowering her body, with a muffled sound, she fell down heavily, in order to slow down the speed of the fall, the ten fingers of both hands curled up on the ice wall to pull out seven or eight finger marks.

Liu Yiyang successfully slid down the ice pier, she couldn't care about the few blood-soaked fingers that were pulled over her nails, and quickly got up and ran to Pan Yueming not far away.

Through the light reflected by the sleigh on the ice wall, Pan Yueming was seen lying on his back on the ice, the helmet on his head was shattered, and he did not know the injury on his face.

"Wake up, master," she shouted loudly as she carefully removed Pan Yueming's helmet.

"Well......", Pan Yueming, who had removed his helmet, was stirred by the cold air and made a soft sound.

"We're ...... Where is it......? Pan Yueming asked intermittently.

"Our sleigh hit this ice wall, and I just woke up.

Oh my God, wait a minute......", Liu Yiyang replied by pointing to the sleigh with one hand and looking carefully at the ice wall in front of him.

What kind of ice wall is this, more than ten meters high, you can't see the edge left and right, and it extends to the end of the line of sight, what a piece of ice it must be, Liu Yiyang was so shocked that he couldn't say much.
