Chapter 405: The Horror of Nuclear Winter

As the images from the detector played, Liu Xiu and his team witnessed the destructive power of nuclear winter.

Of course, the term nuclear winter is not only present in the world before Liu Xiu traveled through time. The term nuclear winter also appeared after the invention of nuclear weapons on the Wandering Blue Star. Of course, Liu Xiu believed that the alien humans must also understand the meaning of this term.

After all, as the first killing weapon ever mastered by mankind, the harm that nuclear weapons can cause is by no means limited to the shock wave at the time of the explosion, nor is it limited to the nuclear radiation after the explosion. What will really lead to human extinction is actually the nuclear winter.

Nuclear winter is a climatic disaster that occurs after a nuclear war breaks out. Its impact is profound enough to cause plants to die quickly and then drive the entire human race on the planet to extinction!

After every nuclear weapon explosion, a mushroom cloud will rise. This cloud is made up of smoke and ash. Under the blessing of the nuclear explosion shock wave, the mushroom cloud will rise into the air at an extremely fast speed. After rising to a high enough position, it will spread horizontally to the surroundings, forming a huge and thick nuclear explosion cloud.

If only one nuclear bomb explodes, the volume of the nuclear explosion cloud is limited and can only block the sunlight in one area and affect the weather in one area. It will slowly disappear after two days and will not cause much impact.

If tens of thousands of nuclear bombs exploded at the same time, and the explosion took place in industrial cities, tens of thousands of mushroom clouds would rise on the blue planet, and hundreds of millions of tons of smoke and ash would be brought into the atmosphere. Two days later, the smoke and ash would reach the troposphere, and after being heated by the sun, they would continue to rise and enter the stratosphere.

Once hundreds of millions of tons of smoke and dust enter the stratosphere, it will bring devastating harm. As we all know, all rainfall is below the stratosphere, and there is no rainfall in the stratosphere. This means that hundreds of millions of tons of smoke and dust will stay in the stratosphere for more than ten years. They cover the sky and block most of the sunlight, causing the temperature on the surface of the blue planet to drop sharply, and nuclear winter officially arrives.

Scientists say that once nuclear winter comes, the global temperature will remain at around minus 40 degrees Celsius. There will be no more sunshine, no more dawn, and the sky will be full of dark clouds and the weather will be freezing cold.

Long-term darkness and cold will cause the plants on the blue planet to die quickly, agriculture will begin to collapse, and those humans who survive will slowly go to extinction due to the torment of lack of food, water and warmth.

However, nuclear winter is so terrifying, but will it really happen? After all, it is impossible to really use Blue Planet for experiments, and no human being would be so crazy as to do so, except for a group that claims to be superior to all humans.

In the world before Liu Xiu traveled through time, the nuclear winter theory first appeared in a scientific journal in 1983. The proposer was an academic group called TTAPS. Once this theory was proposed, it immediately attracted the attention of scientists all over the world. The scientists of Giant Bear even connected with the TTAPS academic group on TV to learn the specific details of the nuclear winter and expressed their agreement with the theory.

However, in the eyes of ordinary people, the theories proposed by scientists and reported by TV stations mean that scientists and TV stations are the truth. As a result, the nuclear winter theory has been widely spread and most ordinary people believe it. However, some top scientists have raised doubts, such as Edward Teller, the father of hydrogen monohydrate. He never believed in the nuclear winter theory from beginning to end.

The father of hydrogen monotherapy said that when Mount Tambora erupted in 1815, the eruption energy was equivalent to 800 million tons of TNT, which is equivalent to the power of 50,000 Hiroshima atomic bombs. 70 billion tons of dust entered the atmosphere. Such a horrific explosion only reduced the temperature by three degrees. How could a nuclear winter reduce the world to minus 40 degrees Celsius!

After all, up to the time before Liu Xiu traveled through time, the Blue Star world had conducted more than 2,000 nuclear tests. The largest nuclear test had a power of 50 million tons of TNT equivalent, equivalent to 3,800 small bombs. However, so many nuclear explosions failed to cause the Blue Star to enter a nuclear winter. Even before Liu Xiu traveled through time, humans on the Blue Star were still troubled by global warming.

Judging from the surface data, humans may really have overestimated the power of nuclear weapons. Although nuclear weapons are terrifying, they will not cause the blue planet to enter a nuclear winter.

According to data from the era before Liu Xiu traveled through time, the current number of nuclear bombs in the world was about 13,000, of which Daxiong had the largest number of nuclear bombs, reaching 6,255, followed by Mijun, with 5,555, and more than 1,000 distributed in other countries, that is to say, the number of nuclear bombs that can be detonated simultaneously in the world is 13,000. After a rough calculation, it is known that the total amount of the explosion of more than 13,000 nuclear bombs in the world is about 100 billion tons of TNT equivalent. Of course, the actual air may be doubled, after all, some are hidden, but even 200 billion tons of nuclear bombs is only equivalent to 250 eruptions of Mount Tambora.

The strongest earthquake in the history of Blue Planet was the magnitude 9 earthquake in Zhili, which had a power equivalent to about 10 billion tons of TNT. In other words, if all the nuclear bombs in the world were detonated together, twenty magnitude 9 earthquakes would occur on Blue Planet.

It's just that twenty magnitude 9 earthquakes occurred at the same time. For the blue planet, it would be just a minor incident and harmless, but for mankind, it would be a devastating disaster.

However, if there were 250 eruptions of Mount Tambora simultaneously on the entire blue planet, the consequences would be extremely terrible. You know, the eruption of Mount Tambora that year affected the entire Asia and the Pacific region, and caused the global temperature to drop. The summer of that year was called the year without summer!

With 250 eruptions of Mount Tambora, the cumulative power is certainly not as simple as the father of hydrogen monotherapy said. It is just like sometimes one plus one is greater than two or even greater than ten.

Now, Blue Planet No. 2 has used an experiment that almost wiped out all the life on the planet to prove that nuclear winter is real and that the ecological environment of Blue Planet is extremely fragile. It is by no means as simple as the father of hydrogen mono says.

Of course, using billions of humans to prove the nuclear winter is extremely stupid, but in fact it is also a last resort. After all, if this is not done, the entire Blue Planet No. 2 will become the territory of the Zerg.

After all, there are still at least three billion people struggling to survive, and the nuclear winter has at least caused huge damage to the Zerg.

The cold doesn't just affect humans, it affects all carbon-based life.

At least under the detection of stealth drones, many surviving Zerg who wanted to attack the plateau area were frozen into insect-shaped ice sculptures.

However, as Liu Xiu used his friendly and enemy map to explore, he discovered that although the surface temperature of the entire Blue Planet No. 2 had dropped to minus 30 or 40 degrees Celsius due to the nuclear winter, all Zerg had not been eliminated.

Because the Zerg queen is not stupid and her IQ is not low.

Because it builds its nest three or four thousand meters underground, using geothermal heat to keep itself warm and resist the cold.

This is the same principle as the wandering humans on Blue Star building an underground city five thousand meters underground.

Of course, although the Zerg Queen saved her own life, it was impossible for her to continue to destroy the surviving humans.
