  Chapter 172 The possibility of the sixth mass extinction (4K, ask for a monthly subscription)

  Pooh~

  The cargo door opened, and the cold air rushed in, and a few people in protective suits felt a burst of coolness.

  Tan Mingda was facing the door. He pushed aside the mist from the cargo hold with his hand, and immediately saw the fruit stuffed to the brim.

   is sealed frame after frame, and the holes around the edges can still see some bright colors.

   "Apple here, Sydney over there..."

  Wang Lei held the manifest in his hand, and reported the varieties to everyone. They were basically apples and pears that were storable. In addition, there were also a small amount of bananas, plums, peaches, etc. that were purchased on the spot by Huantai.

   Seeing this truck of fruit with his own eyes, Tan Mingda and the others showed smiles on their faces, and their eyes seemed to recall the past.

  The other people who came with Tan Mingda stared straight into the car.

  No one spoke, but their emotions were already expressed in their eyes.

   This is a desire.

   Seeing their reactions, Zhang Tianyuan knew that this meeting ceremony was the right one.

  These fruits and grains are not valuable, but they are exactly what this time and space desperately needs.

"alright, alright…"

   "Close the door, don't get sunburnt."

   Seeing that in the hot and dry environment, the surface of the fruit in the car kept dripping to the ground, and Tan Mingda, who was heartbroken, stopped this meaningless exhibition.

   Then he turned around and asked people to arrange a warehouse to seal up the fruits.

  The fleet of wandering time and space also followed the arrangement and drove towards the warehouses.

   Zhang Tianyuan clearly felt that as the fruits and grains entered the warehouse, Tan Mingda and others had a lot more confidence in themselves.

   They even returned to the car and took the initiative to learn about the mutual rescue association.

   "If we choose to join, can you really meet the standards stated in this application?"

  Tan Mingda held a membership application in his thin hands.

   As for the question, it is naturally whether the Mutual Rescue Society will not interfere in their internal affairs.

   Zhang Tianyuan smiled and understood his worries.

   After all, now Tan Mingda and the others have actually achieved the position of world hegemony, and they can even send people abroad to mine resources and carry out rescue.

   As long as they follow this trend, the whole world will sooner or later become Tan Mingda's sphere of influence.

  America, which was left alone, could not escape in the end.

   Originally this future was visible to the naked eye.

  As a result, there is a mutual rescue meeting suddenly appearing, which is undoubtedly a huge variable.

   Zhang Tianyuan pointed to the application and said, "I can only say that the Mutual Rescue Association has gone through four times and spaces so far, and has not violated any terms of the agreement against any member state."

   "If Mr. Tan definitely wants to prove it, he can wait until later to learn more about it from other time and space."

   "It seems that President Zhang is very confident..." Tan Mingda closed his eyes gently, as if he was seriously considering whether to join the Mutual Rescue Association.

   The old woman next to him also remained silent.

   It's just that Zhang Tianyuan thinks that the two of them are still thinking about the truth of the Mutual Rescue Association.

   Suddenly, he remembered something.

   "Mr. Tan knows that your time and space has actually begun to recover?"

"recover?"

  The silence was suddenly broken.

  Tan Mingda and the old woman's eyes suddenly focused on Zhang Tianyuan's young face.

   "Yes, now your earth may have entered a recovery period, and some places can now allow people to live normally."

   "Where?" The old woman couldn't help but say.

   Zhang Tianyuan thought for a while: "San Francisco, there should be a large area of ​​land there now that has returned to relatively normal temperature and radiation values, at least allowing people to move normally for a short period of time."

   At the end of the movie, the protagonist is from the middle to the west, 18 hours away from the Golden Gate Bridge, and basks in the sun for the last time.

   And there, the temperature has returned to normal.

   After driving all the way to the Golden Gate Bridge, the vegetation along the way began to recover, and the green re-occupied both sides of the road.

   It can be seen that the land area that has returned to normal is not small.

  …

   Considering that the two of them would definitely ask him how he knew, Zhang Tianyuan spread his hands and said, "You don't need to ask how I know."

  Tan Mingda was more calm, and he changed the question: "Does President Zhang know of other areas that have returned to normal?"

   "I don't know." Zhang Tianyuan answered very succinctly.

  Tan Mingda looked at the old woman beside him, and the long-standing tacit understanding allowed them to communicate with their eyes only.

No need to say anything, the old woman already knew what he meant, and she took the initiative: "I will arrange a satellite reconnaissance mission later, and I will ask the aerospace department to launch a few more satellites. Our focus on North America is indeed not enough."

  Tan Mingda nodded, looked back at Zhang Tianyuan, and thanked him.

   For this news, they would rather kill the wrong person than let it go.

   However, Zhang Tianyuan suddenly spoke again: "Although it means pouring cold water, I don't think this is necessarily good news, because there are several other possibilities for the situation in San Francisco..."

  The old woman looked over in astonishment: "What do President Zhang's words mean?"

   "In response to the phenomenon of temperature recovery in San Francisco, in fact, our Mutual Rescue Association once held a seminar with meteorological experts from various time and space before reaching your time and space."

  Tan Mingda's heart tightened when he heard this: "How was the result of the seminar?"

   "The situation is good and bad," Zhang Tianyuan took out a document that recorded the results of those seminars:

"Because the thickness of the ozone layer varies from region to region. So the best result is that the ozone layer in the San Francisco area may be thicker, blocking more UV rays, and maintaining a more comfortable temperature due to monsoons or ocean currents. …”

  Wang Lei was responsible for handing the two identical documents to Tan Mingda and the old woman, and his expression was very solemn.

   He was recruited for this task before that seminar, so he watched the entire seminar and knew the result.

  Tan Ming Damo was holding the paper in his hand, and suddenly he didn't dare to open it.

   He glanced at the old comrade next to him, who also stared at the document cover in a daze.

   In the end, the skinny old man sighed and said directly, "I'm sorry to trouble President Zhang."

   Zhang Tianyuan's complexion was even more dignified than Wang Lei's.

   "Another result is a bit more complicated."

   "The ozone layer, as you all know, is actually the decomposition of oxygen molecules in the atmosphere into atoms after being irradiated by high-altitude short-wave ultraviolet rays.

   These oxygen atoms react with oxygen molecules to form ozone, which falls to the bottom of the ozone layer due to specific gravity. Finally, it is affected by the rising ambient temperature after falling and the irradiation of long-wave ultraviolet rays, and it is reduced to oxygen again... This dynamic equilibrium process constitutes the well-known ozone layer. "

   To put it bluntly, oxygen is synthesized into ozone at the top of the ozone layer, then falls below, and is reduced to oxygen again, and then continues to cycle through this process, thereby forming the ozone layer.

  Tan Mingda and the old woman nodded, indicating that although they were old, they still understood.

   Zhang Tianyuan opened a page of the document, pointed to the content above, and described the process of solar storms destroying the earth's ozone layer.

   The process is simpler.

  After a solar flare erupts, the ejected high-energy protons ionize nitrogen and oxygen molecules in the atmosphere and form nitrogen oxides.

  These massively formed nitrogen oxides continuously chemically react with ozone to reduce it into oxygen molecules and oxygen atoms.

   And after the solar flare erupts, the output intensity of ultraviolet radiation will also increase.

   After these radiations are absorbed by the earth’s atmosphere, the atmosphere will be heated, resulting in an increase in the temperature and density of the atmosphere, and ozone will naturally be decomposed in large quantities…

   "Generally speaking, the destruction of the Earth's ozone layer caused by these two methods, as long as it is not large, can be recovered within a few years."

   When Zhang Tianyuan said this, he paused.

  Tan Mingda then took the initiative to say: "The solar storm 15 years ago was an exception. Our ozone layer was melted in almost a day."

   "Yes," Zhang Tianyuan nodded, and he rubbed his brows: "The intensity of the solar storm you have experienced is unprecedented, and this is what worries us the most."

   "That is, that solar storm, is it possible that it not only destroyed your ozone layer?"

   Hearing this sentence, the old woman seemed to have been electrocuted, and she squeezed her scarred hand tightly.

  Tan Mingda also thought of something.

   "I saw a report before with a similar presumption that the solar storm may have caused the Earth's air molecules to be destroyed..."

   "Well." Zhang Tianyuan continued: "In other space-time studies, there is a view that the first mass extinction 440 million years ago was caused by a supernova explosion."

   "The gamma-ray burst caused by that burst hit the Earth directly, destroying the ozone layer within 10 seconds, and at the same time destroying the molecular structure of most of the air in the atmosphere."

   "In the decades after the ray burst, the air molecules in the atmosphere were recombined to form a large amount of nitrogen dioxide, which blocked a lot of ultraviolet rays, but also blocked a lot of sunlight..."

   Speaking of this, Tan Mingda's eyebrows twitched unconsciously, indicating his mood at the moment.

   He interrupted: "Our time and space have similar inferences."

   Zhang Tianyuan raised his head and glanced at him, realizing that this time and space were also aware of the risks.

   "After the sun was blocked at that time, the earth ushered in a permanent ice age. About 10% of the sea water was frozen, and the sea level dropped by about 100 meters."

   "This catastrophe lasted about 400,000 years, when 85% of the species on Earth went extinct..."

   "Is President Zhang worried that our time and space will be the same as that mass extinction?"

   "This time and space may indeed lead to such an ending."

   Zhang Tianyuan lowered his eyes, and there was a sigh in his tone.

   After several time and space, he has long known that the movie world is not exactly equal to the movie.

  Although the movie seems to give an ending in which nature recovers and humanity regains hope.

   But from a scientific analysis point of view, the climate recovery in San Francisco may indeed be a short-term beauty.

The real ending of    may be similar to the inference of the first mass extinction.

  The air molecules that were originally destroyed by the solar storm are now reassembled into substances other than ozone, blocking the sunlight and ultraviolet rays in that area.

  The atmosphere in the car fell into a dead silence.

  Tan Mingda's heart was also messed up.

   A similar theory had indeed been reported to him by meteorologists before.

   It’s just that at the time, it was thought that this possibility was relatively small.

   After all, no matter how much the sun is tossing, it is impossible to release the same energy as gamma-ray bursts.

  The energy of the gamma rays emitted thousands of light-years away has been weakened a lot after a long cosmic space, but it still took only ten seconds to destroy the earth's ozone layer, while the original solar storm took a day.

   From this we can see how big the energy gap is.

   But the sudden appearance of the San Francisco recovery area suddenly made him unable to calm down.

  At the beginning, the ozone layer of the earth was completely destroyed, and even their latitudes could see the auroras that are usually only at the poles.

   This level of damage cannot be recovered within ten years.

   As a result, the ozone layer has now recovered in the San Francisco area?

how is this possible? !

   Looking at Tan Mingda's gloomy face, Zhang Tianyuan comforted him at the right time: "Mr. Tan, don't worry too much, the specific result is still uncertain now, maybe it will be a good result after investigation?"

   However, Tan Mingda just closed his eyes and shook his head.

   Even if he doesn't understand the weather, he knows that there will be no good results.

   "The best result now may be that our ice age comes a little slower and warmer..."

  Tan Mingda only lowered his head for a moment, then picked himself up again.

   "President Zhang, thank you."

   "We will send people to San Francisco for a field investigation in the near future."

   Maybe it was because both time and space suffered the sin of the sun, so Wang Lei on one side couldn't help but reminded: "The time and space tunnel of our mutual rescue club can help you reach San Francisco directly."

  Tan Mingda looked at Zhang Tianyuan hesitantly.

   is like doubting the authenticity of the time-space tunnel, and also asking if the tunnel can be borrowed.

   Zhang Tianyuan didn't care so much, he laughed and said, "Exactly, we also want to explore San Francisco."

   At this moment, a message was reported from the team.

   All supplies have been unloaded, and now the vehicle and driver have been reassembled.

  Wang Lei reported the news to Zhang Tianyuan.

   Zhang Tianyuan also knew that the time was up: "Let's go then, let's send your convoy back first, and then have a good talk with Mr. Tan about the weather survey."

  Two minutes later, the people who put on protective clothing again got off the command car.

   Zhang Tianyuan helped the old Tan Mingda down and followed him slowly towards the convoy.

  Wang Lei is responsible for the roll call to ensure that all vehicles and personnel are in place.

   Then at the end of the road, a time-space tunnel leading to wandering time and space was opened.

  The convoy began to set off for home.

   Seeing the trucks disappear after passing through the tunnel entrance, the old woman couldn't help but stunned, and even pinched her fingers secretly to make sure she was not dreaming.

  Tan Mingda kept his surprise in his eyes, and murmured while watching the long motorcade return:

   "It's a good thing."

   It’s too painful for liberal arts students to write this, so they check the information while writing. If there is any omission, please pretend that you didn’t see it…

   Finally, ask for a monthly pass at the beginning of the month! !
