December 26, 2035, at 8:15 Greenwich Time.

After the unification of meteorologists from China, the United States, Europe and Russia, Professor Li Jinlong, the general manager of the Genesis project and the chief meteorological scientist of China, issued a detonation order.

At this moment, it will inevitably be recorded in the history of mankind, and the fate of mankind has also changed. [bsp;    But no one was excited at that time.

The name "Genesis" was taken by an American scientist, and it is also very appropriate to the responsibilities he bears and the impact on future generations.

At 8:16, the earthquake observation station located in Greenland first sent out a signal: the detonation was completely successful.

According to the earthquake intensity signals detected by more than 1,000 earthquake observation stations around the world, the energy released by detonation ranges from 4.7 billion tons to 4.9 billion tons TNT equivalent, which is equivalent to more than 97% of the nuclear warheads being detonated successfully, and Iceland has instantly become history.

Because the energy released by the explosion is huge, it is impossible to observe it at close range

As for observation in low-Earth orbit, it is even more impossible, because all the remote sensing satellites launched by the four sides were destroyed by space garbage, and artificial spacecraft could not be deployed to low-Earth orbit for the time being.

However, many people still witnessed this unprecedented explosion.

At that time, more than a thousand observers in Greenland, eastern Canada, Norway and northern Britain saw the mushroom clouds produced by the explosion.

According to the data measured by the ground observation station, the explosion basically achieved the expected effect.

Of course, the final conclusion will take several days to come to the conclusion.

Four hours later, the first drone arrived near the explosion site and began to shoot the explosion scene and collect dust in the air.

By the evening of that day, more than a hundred drones had arrived.

The data collected by the drone is sent to scientific institutions in China, the United States, Europe and Russia in real time, and scientists from the four sides conduct a comprehensive assessment of the explosion results.

In the next few days, billions of people around the world are waiting for the conclusions of scientists.

Although there have been signs that the explosion was very successful, because on December 27, the ash floated over the European continent, and the Scandinavia, the United Kingdom, the Netherlands, Belgium, northern Germany, Denmark and other countries were seriously affected. The ash fell in some places was more than ten centimeters thick, but before scientists gave clear conclusions, no one knew how much dust would enter the stratosphere, and it was impossible to know whether it could block enough sunlight and reduce the temperature in the Arctic region by more than five degrees Celsius.

Only when this standard is met can the Arctic region be fully frozen in the next month.

In fact, thirty-one days ago, scientists from all sides came to the conclusion that there were only differences and no unified report was given.

To this end, Sifang scientists spent two days comparing the analysis process.

On December 31, the chief representative of the Quadrilateral Scientists Group issued a joint announcement at the Global Climate Affairs Organization: the explosion has achieved its goal and exceeded its expected results.

During this big explosion, 15 billion to 17 billion tons of dust entered the stratosphere.

Now, the problem arises.

According to scientists' estimates, at most one billion tons of dust is needed to enter the stratosphere, which can reduce the effect of sunlight radiation heating by 30%, ensuring that the Arctic ice sheet will return to the same level in previous years within the next month. After the increase in the amount of dust by more than 50%, the sunlight radiation heating effect will be weakened by about 40%. Therefore, the Arctic ice sheet will not only return to normal within one month, but will also extend by more than 15%. What's more, the blocking effect of dust will continue, and the low temperature situation in the Arctic region will last for more than four months until the end of May 2036, before reaching the usual temperature level in March. In other words, the Arctic ice sheet is not only preserved, but also enhanced. If the dust in the stratosphere is not eliminated as soon as possible, the Little Ice Age will arrive early.

Obviously, this is the most deadly thing.

Although theoretically speaking, it is only necessary to increase the output of stratosphere aircraft by 50% to complete the dust cleaning work within one year, the most important thing is not the overall output, but whether enough stratosphere aircraft can be manufactured within the first three months.

To put it bluntly, in the first three months, about eight billion tons of dust must be removed.

According to the original plan, only 3 billion tons of dust need to be removed. According to the calculation that a stratosphere aircraft collects 300 tons of dust every day, at least 100,000 aircraft will be needed in the first three months. The reality is that even if the production of various countries can be achieved, the second assembly plant will be put into production immediately, and only 50,000 aircraft will be able to be manufactured within three months. Obviously, it is impossible to achieve the ideal situation. The most optimistic estimate is to manufacture 30,000 aircraft.

The conclusion is simple: Even if countries produce at maximum capacity, they cannot produce enough stratospheric aircraft by the end of March 2036.

In other words, other ways must be considered to prevent the rapid expansion of the Arctic ice sheet.

In response to this problem, scientists proposed an effective solution: detonate unused nuclear warheads under the Arctic ice sheet.

Nuclear weapons use atomic energy, not internal energy.

In other words, using nuclear weapons is equivalent to releasing energy to nature, and these energy will eventually be transformed into internal energy, increasing the overall temperature of the earth.

Fortunately, there are enough nuclear warheads.

At that time, only five nuclear powers had nearly 10,000 nuclear warheads. After the big explosion, there were more than 4,000 left, with a total equivalent of about 2 billion tons of tnt. If nuclear raw materials that have not been destroyed were used, about 5,000 nuclear warheads with an equivalent of about 1 million tons of tnt can be made within three months. So many nuclear warheads are enough to slow down the condensation rate of the Arctic ice sheet in the short term.

For human civilization, the most critical thing is the first three months.

As long as the Arctic ice sheet does not freeze over the scale within these three months, the effect of sunlight radiation heating will increase significantly after the stratosphere aircraft starts to work, which can prevent the Arctic ice sheet from freezing.

Without a way out, more than 100 countries around the world mobilized again.

To be precise, they are five nuclear powers.

In order to ensure that no country can take this opportunity to obtain the ability to manufacture nuclear weapons again, the assembly and deployment of nuclear warheads are carried out under the supervision of the Quadrilateral agencies, and all newly produced nuclear warheads are marked separately to ensure that they are used in places where they are used.

No one knows whether this is useful or not, but everyone knows that there is no second choice.

On January 1, 2036, after the first batch of spare parts were delivered in advance by various countries, the production line of the stratospheric aircraft assembly plant was officially launched.

Two days later, the first nuclear warheads were detonated under the Arctic ice sheet.

According to the theory proposed by scientists, detonating nuclear warheads in batches can most effectively prevent the ice cap from freezing and slow down the expansion speed of the ice cap. If the nuclear warhead is detonated in a concentrated manner, at most some ice caps can only melt at most, which is not much helpful in preventing the ice cap from expanding rapidly. Because the ice caps will also reflect sunlight, and the reflection efficiency is much higher than that of dust, so preventing the ice caps from expanding to the most effective way to prevent the temperature from dropping rapidly.

In other words, the role of a nuclear warhead not only releases heat, but also blows up the ice sheet and allows the Arctic Ocean to absorb more sunlight.

On January 10, the first batch of stratosphere aircraft were removed from the line.

Although time is extremely tight, Mu Haoyang still arranged the test flight as planned. Because it is a drone, the test flight work is relatively simple, mainly to see whether it can rise to the stratosphere and whether the electrostatic adsorption device it carries can meet the designed working indicators.

The test flight results were very ideal.

Within one day, the ten stratospheric aircraft participating in the test flight absorbed more than 300 tons of dust, and the high-pressure compression device developed by Brazil worked normally. The "stone balls" produced by dust compression were thrown to the recycling sites distributed in the northern hemisphere according to the predetermined procedures.

To ensure that dust no longer enters the atmosphere, most of the recycling sites are on the sea surface, and some are inland lakes.

For example, Lake Baikal, the deepest in the world.

If the recycling work goes smoothly, it will take only half a year before Lake Baikal will be filled with "stone balls". To this end, Russia has specially excavated three canals, introducing the water of Lake Baikal into the Arctic Ocean through the Nise River and the Lena River to the Arctic Ocean, and introducing it into the Amur River to the Pacific Ocean.

While doing this project, Russia also transferred more than 5,000 Baikal seals.

You should know that Baikal seal is the only seal in the world that lives in a freshwater lake. It has unique biological characteristics and is a very precious species.

On January 14th, the cleaning work began in full.

On that day, 120 stratosphere planes code-named "Angel" were launched one after another.

It was also from this day that more than 20 "angels" were launched from the assembly plant every hour, and the airport specially opened by the Chinese Marine Corps.

All of these aircraft are powered by electric propellers. In the troposphere, the batteries provide electricity. After rising to the troposphere, the solar panels provide electricity. Because the cruise flight speed is 800 kilometers per hour, it flies west during the day and east at night, so the flight time is about six hours at night, and the batteries on the aircraft can provide the electricity required for continuous flight for eight hours. That is to say, the "angel" does not need to return to the ground to charge, and can fly in the stratosphere all the time as long as there is no mechanical failure.

Of course, this is just an ideal situation.

Because the electrostatic adsorption device needs to consume electricity, the compression system also needs to consume electricity. In addition, each system on the plane has a maintenance cycle, so on average, the "angel" has to return to the assembly base for about four hours of maintenance, and then take it off again.

To ensure that no country can get these planes, the "angel" has a self-destruct device.

In addition to receiving special signals near the assembly base, at any location, as long as the flight altitude is less than 18,000 meters, the "angel" will destroy itself.

Obviously, countries around the world are also guarding against other countries when they are trying to save themselves.

It is also true that Mu Haoyang has to admit that human civilization has not been improved due to this disaster, and at least it has not made any efforts to unify it.

Disasters are definitely not the main driving force for human union.
