When they saw Su Leyan coming in, everyone's eyes lit up. You know, Su Leyan is the backbone of their base and his prestige is greater than Zhang Jianguo.
"Xiao Su, come here. We are discussing the next arrangements. You just came back from outside, right? See if you have any opinions. We need to pick up those soldiers as soon as possible!"
"Everyone, the situation outside is more serious than we imagined!"
As soon as Su Leyan opened her mouth, the entire conference room straightened up instantly, and everyone stared at her intently.
They believed that Su Leyan would never joke about this matter. She said that this was definitely a serious problem. It seemed that the global climate change was really a huge survival test for mankind!
It is impossible for humans to live forever within the protection of the energy shield. Humans are social animals. They need to communicate with each other and need to restore their previous lives. If they simply live, they don’t need to think so much, but they need to consider the next generation.
"Xiao Su, don't worry that we can't accept it. If you have anything to say, just say it!"
"This sudden drop in global climate is due, on the one hand, to severe atmospheric pollution, and on the other hand, to the Blue Planet's orbit deviating from its original orbit, causing it to move away from the solar system. Everyone, please watch!"
Su Leyan turned on the computer, and soon, a map of the universe appeared on the projection screen. The orbit of the blue planet had deviated from its original orbit!
Su Leyan kept tapping on the keyboard with his hands, and a series of complex codes quickly flashed across the projector. After more than ten minutes, the codes were replaced by two maps of the orbits of planets in outer space.
"Please look, everyone. This blue planet is the Blue Planet we live on. These are the Sun and the Moon. The Sun is the center of the solar system, a fixed star. The Blue Planet is a planet in the solar system, orbiting the Sun. The Moon is a satellite of the Blue Planet, orbiting the Blue Planet."
"From this picture, we can see that the Blue Planet's orbit is still revolving around the Sun, but it has gradually deviated from its original orbit. This has also caused the Blue Planet to stray from the Sun. Once it completely deviates from its orbit, the Blue Planet will fall into endless darkness!"
Everyone looked at each other, feeling a little confused.
They are not scientific researchers, so they don't understand the relationship between the two. After all, they are discussing climate change, not the orbit of the blue planet.
"Any slight change in a planet's orbit will affect the distribution of solar radiation on its surface. While this won't significantly impact the planet's annual average, it could significantly affect regional and seasonal radiation levels. There are three types of changes in a planet's orbit: orbital ellipticity, axial inclination, and precession."
"The combination of these three changes forms the Milankovitch cycle, which is the main reason for the ice ages and interglacial periods on the blue planet, and is also the main reason for the changes in the La Desert and the formation of the strata."
"Right now, the climate across the country is changing dramatically. The orbit of the blue planet has deviated from its original path. This is closely related to climate change. Do you understand what I mean?"
"clear!"
If they didn't understand, they would be really stupid. That is to say, just a slight deviation from the orbital change will cause climate change. Because the atmosphere is polluted, oxygen is lost and the air becomes thin. This has a huge impact on the blue planet!
If this is just the beginning, then once the orbit of the blue planet completely deviates from its orbit, it will be a devastating blow to the blue planet!
"Miss Su, is there any solution to this situation?"
The end of the world was finally about to end, but now they heard more bad news, one after another, and their hearts were filled with panic!
As early as more than a decade ago, the international community has been calling for environmental protection. However, how many countries can actually do so? After all, many countries develop first and then govern, which has caused serious environmental pollution.
Ultimately, it is the sins committed by humans themselves that have led to the sudden change in climate.
"What we can do now is to adapt to the sudden drop in the environment as quickly as possible and reset the Blue Planet before its orbit completely deviates from its course."
"Once we lose sunlight, not only will humanity be plunged into endless darkness, but oxygen will also gradually disappear. Once oxygen completely disappears, even within the energy shield, human survival will be difficult to guarantee!"
Oxygen is an indispensable substance for creatures on the blue planet.
In the human body, oxygen can participate in various biochemical processes to maintain the operation of life. Once it leaves oxygen, a person will die within a few minutes.
In the atmosphere of the Blue Planet, 78% is nitrogen, 21% is oxygen, 0.9% is argon, and 0.1% is other gases. However, the oxygen content does not always remain at 21%. Throughout history, the oxygen content in the Blue Planet's atmosphere has fluctuated many times.
Even for the first 2 billion years of our planet's existence, there was almost no oxygen. That changed when a type of organism called cyanobacteria appeared.
This organism contains chlorophyll and can carry out photosynthesis, converting carbon dioxide in the atmosphere into oxygen. Coupled with the release of some gases by volcanic eruptions, the blue planet ushered in the Great Oxidation Event, which has since become suitable for the existence of life that relies on oxygen.
From then on, photosynthesis became one of the decisive factors in the oxygen content in the atmosphere of the blue planet. At one point, because there was too much oxygen, a 3-meter-long "giant centipede" and a giant dragonfly with a wingspan of 70 centimeters appeared in the Carboniferous period.
In even more exaggerated cases, the excessively high oxygen content in the blue planet even caused a sharp drop in temperature 2.4 billion years ago, and the ice sheet once extended to near the equator, which is the famous snowball period of the blue planet.
After a long time, the oxygen content of the blue planet has reached 21% today, which is quite comfortable for humans.
However, studies have shown that the blue planet's oxygen-containing atmosphere is not a permanent feature.
In the future, plant photosynthesis will still greatly affect the oxygen content on the blue planet.
However, how these plants grow also depends on another factor: the sun.
Nothing in the world is permanent, including the oxygen we breathe and the sun.
The Sun has been shining and heating itself through nuclear fusion for billions of years and will continue to do so for the next 5 billion years.
The principles of nuclear reactions remain constant, but the sun itself does change. As the sun ages, it will gradually begin to heat up, becoming hotter and hotter, causing the temperature of the blue planet to continue to rise.
When the temperature of the sun rises to a certain level, the carbon dioxide in the blue planet's atmosphere will undergo decomposition reactions, gradually reducing its content.
You might think that the disappearance of these greenhouse culprits is a good thing, but it is not. This is because a large number of organisms still rely on them for survival, namely plants.
