I! Pretending to Be Reborn, Director of Doomsday Hoax

In the history of Blue Star, since it was recorded, the maximum wind level was seventeenth, ranging from 220 kilometers to [-] kilometers per hour.

The 54-level wind will wash away the soil, tear up the plants and any creatures that live nearby!

Moreover, because the meteorite is too big and the shock wave is too strong, an area with a diameter of about [-] kilometers will be destroyed during the landing in the air!

And the radius of the blue star is 10,000 kilometers, which means that a meteorite of [-] taels kilometers will destroy more than a quarter of the diameter of the blue star before it lands!

Xu Qiu's eyes were full of caution, and he was performing rapid calculations in his mind.

"A meteorite fall will trigger a larger and more violent volcanic eruption. The temperature of the plume rising from the crater can exceed [-] degrees Celsius, which is equivalent to twice the surface temperature of the sun...

"This will cause a huge fire within a range of [-] to [-] kilometers. Non-combustible materials will become a joke at this time. The extreme high temperature will cause water to evaporate in an instant and become a combustion accelerant." Xu Qiu's complexion , very dignified.

"Humanity is already extinct in the first month when the sun goes out, and no one knows what happened after the first month.

"So, I don't know, after that, will it be a volcanic eruption or a meteorite impact..."

Xu Qiu frowned and continued to talk.

According to the asteroid impact accident that exterminated the dinosaurs and reshaped the biological structure of the blue star six thousand and five million years ago.

Within a few days of the asteroid impact, the entire blue star will be turned into a fireball.

In the first hour, the impact triggered a global earthquake with a magnitude of over eleven. Everything on the surface will be destroyed, and Mount Everest will also collapse under such a strong earthquake.

At the same time, all the glaciers melted. First, near the ground where the meteorite fell, the glaciers directly vaporized and turned into high-heat water vapor, which brought down high-temperature rainwater close to the boiling point, and then melted the entire Blue Star glaciers.A large number of areas will be submerged, the ocean will freeze, and a huge tsunami up to 300 meters will be born, bringing a second devastating blow to the creatures of the blue star.

The impact of the asteroid on the blue star will detonate tens of thousands of tons of meteorites, and the remnants of the asteroid will be impacted into the atmosphere.

Some of these elements went into orbit, while the rest returned to Earth as densely burning meteors, including intense heat pulses from larger ejecta backflows that caused global forest fires.The entire terrestrial biosphere, the organisms that survived the earthquake of magnitude 300 or above and the tsunami above [-] meters high, will be burned by this terrible fire.

Global wildfires could turn terrestrial ecosystems into ashes...  

It's not the scariest.

With the burning of plant and surface organic carbon,

Huge amounts of carbon dioxide, CH4 and H20 were emitted into the air, some of which came directly from the asteroid's carbonate component, while the rest came from the Earth itself.

According to the asteroid impact 5 million years ago, the impact produced ejecta with a total volume of about 8 cubic kilometers.

包括从350亿吨到3500亿吨二氧化碳，40亿吨到560亿吨的硫，以及200亿吨到1400亿吨的水蒸气。

Well, the end of this time, I'm afraid it won't be too optimistic...

Sulfur compounds are the most important climate-active gases injected into the stratosphere, and this impact, the amount of sulfur released is orders of magnitude higher than any known volcanic eruption,

And the water erupted was enough to cause sudden and significant perturbations to Earth's climate.

The ejecta caused a strong warming of the upper atmosphere after the impact, which probably lasted only a short time.

After several hours, sulfate continues to form and remains in the stratosphere, where it reacts with water vapor to produce a stable, long-lived sulfate aerosol.

Aerosols disrupt the thermal regime of the stratosphere by absorbing long-wave radiation, cooling the Earth's surface and significantly disturbing the global multi-year climate, thereby disrupting atmospheric circulation for several years.And acid rain.

Acid rain should be counted as a secondary product of the impact event.

After the impact, highly corrosive acid rain would fall for several years.

The first is the shock heating of the atmosphere by the impact event, producing nitric acid rain.

Later, it is sulfuric acid rain.

Of course, even combined nitric acid and sulfuric acid rain would not be enough to acidify remelted ocean basins, but its effects on shallow or poorly buffered estuaries and on continents are mixed.Even if all the sulfur was released in the impact, the acidification of ocean surface waters would not be too severe,

However, in the land and nearby shallow water environment, under the ravages of the impact event, the soil is not fertile and unable to buffer the acidification of groundwater. The consequences of acid rain may be serious.

Zou Botao said wait a moment, ran to his office next door, and brought a computer over.

"Director Xu, there is a model I made on it!"

Zou Baitao clicked on it. This is the asteroid impact blue star model made by him, Yang Shaowei and others in conjunction with the Special Computer Engineering Technology Research Department in the past few days.

He explained: "This is just a model of the asteroid hitting the blue star 7 million years ago, before the sun went out."

In other words, Zou Botao and others replayed the scene when the dinosaurs went extinct.

Click to play.

With the fall of a meteorite, what happened in the early days of Blue Star was exactly in line with Xu Qiu's prediction.

Major earthquakes, super tsunamis, and horrific fires raging around the world.

In just a few days, the blue star became a scorching fireball!

Then, a week later.

After the initial high temperature and combustion, most of the burning substances on the surface of the blue star were reduced to ashes, and the fire gradually decreased, and the flames tended to calm down.

Just when Li Bingqing thought the disaster was about to end,

The faces of Xu Qiu and Zou Botao became extremely heavy at the same time...

"After the calm, there will be a bigger crisis!" Zou Botao said in a deep voice.

Xu Qiu also remained silent, with a serious expression on his face.

Li Bingqing choked in his heart, and quickly watched the next development of the model.

Sure enough, after a few weeks, Blue Star fell into a more critical situation.

The impact aerosols and post-impact soot and sulfates reflect sunlight in the upper atmosphere, directly cooling the planet.

And organic smog from forest fires burning fossil organic matter absorbs short-wave radiation, preventing sunlight from reaching the surface, causing a drop in surface temperature, temporarily inhibiting photosynthesis, and causing a global collapse of land and marine food webs.

At this time, only 20.00% of the original sunlight can reach the surface.

This means that the energy supply chain will be reduced by more than 80.00%, which will lead to a severe drop in surface temperature on a global scale in the short term.

"There is another point that requires our special attention. This may be related to the Little Ice Age..."

Zou Botao's face was extremely serious.

According to the model results, the temperature of the blue star will drop by tens of degrees rapidly after the global fire.

The resulting temperature differences can create massive storms and hurricanes between the cold atmosphere and relatively warm oceans.

Zou Botao said in a deep voice: "During the Little Ice Age, the temperature only dropped by dozens of degrees, which was not enough to freeze the ocean, so there will inevitably be raging sea storms..." At that time, we may still need to resist these coming from the sea. Hurricane at sea.From another perspective, Director Xu's skyscraper wind farm can just be verified. "Xu Qiu nodded.

He had already considered the problem of storms in the Little Ice Age.

That's why he urged Mo Hongxi and the others to rush out the prototype of the skyscraper wind farm before the Little Ice Age.

This may be the time when the blue star, before the sun goes out, has the richest wind resource.

It is also the only opportunity to verify the practical performance of various wind farms.

The model on Zou Botao's computer is still developing.

In the months to decades after the impact 5 million years ago, the atmosphere stabilized and dust rained down and accumulated in sedimentary environments.

Among them, there are also asteroid-derived trace elements uranium group elements recognized by the current academic circles, such as table.

Compared with dust, sulfates have a greater impact on the environment.

Aerosols will have a great impact on the atmosphere of blue stars in the next few decades.

Then there is the aquatic environment.

Protected by seawater, the deeper seafloor is shielded from heat and fire, but an impact winter can cause a global mass extinction of phytoplankton in the months to years that follow.Aquatic ecosystems are basically dependent on the sun,

Therefore, when the sun's radiation is reduced by more than 80.00%, the output autotrophs and phytoplankton that strongly depend on photosynthesis will die and become extinct in a short time.Not just lighting.

In the ocean, affected by acid rain, diagenetic coccolithophores and planktonic foraminifera with calcareous shells died and became extinct at the collision boundary.

Ammonites, the most diverse and abundant plankton predators of the Paleozoic and Mesozoic Era, along with the giant mosasaurs, plesiosaurs and pliosaurs that fed on them became extinct within a dozen years, according to tests of the models.

This model of the extinction of the dinosaurs, in fact, may be a microcosm of the human being ten months later.

No, it should be said that the doomsday that mankind will face is even more terrifying...

The asteroid impact 7 million years ago, no matter how terrifying it was, only caused the blue star to sway, producing some dust that covered the atmosphere, and within 100 years, it can return to normal.At least, about 20.00% of the sunlight can reach the surface of the blue star.

But the sun goes out, making all the light disappear directly.

The devastating consequences of this far exceed that of an asteroid impact!

There was panic in Zou Botao's eyes.

"If, supercontinents, continental drift, species extinction...

The first mass extinction of the Blue Star was the Ordovician mass extinction, which occurred [-] million years ago.

In that extinction, about 80.00% of five species died out. According to your instructions, Director Xu, we finally pinned the culprit on the supernova explosion.

After the eruption, the dust cloud blocked the sunlight, large glaciers emerged, the temperature of the blue star dropped sharply, the glaciers locked water, the sea level dropped, the rich coastal ecosystem was destroyed, and species became extinct.

The second time was the Devonian mass extinction, about [-] million years ago.

The Devonian period was a period of rapid development of vertebrates, and fishes were quite prosperous, and various types of fish appeared.

Therefore, the Devonian period is also known as the "Age of Fishes".

In this era, the most important thing is the evolution from the total fins, and the tetrapods, the ancestors of amphibians and reptiles, appeared.

Studies of paleoclimate reveal that the Devonian heyday was warm.

The fossil record indicates a temperate climate as far away as the Arctic.

And this time the Devonian mass extinction was also caused by the cooling of the earth's climate and the retreat of the ocean.

The third time, at the end of the Permian period [-] million years ago.

This is the most serious extinction, with more than 70.00% of terrestrial vertebrates extinct, and more than 90.00% of marine organisms extinct. This is also the only event that led to mass extinction of insects.The impact of this mass extinction took Blue Star's ecosystem millions of years to fully recover...

However, the process and cause of the Permian extinction is still a mystery.

According to existing research, the high probability is a sudden change in the environment. The reason may be an impact event, a super volcanic eruption, or a sudden change in sea level, causing a large release of methane hydrate.

The fourth time, the Triassic mass extinction [-] million years ago.

The fifth time was at the end of the Cretaceous period 5 million years ago, when the dinosaurs became extinct. "

Zou Botao's eyes were protruding, and his expression was a bit ferocious, and he said, "Director Xu, have you noticed that the speed of species extinction is getting faster and faster, and every extinction of creatures seems to be related to the cold...

"If calculated according to this law, then the next mass extinction of species will be the era in which human beings live. Six thousand and five million years after the extinction of dinosaurs, a new era of species extinction will begin!!" Xu Qiu fell into deep thought.

The interval between species extinctions is getting shorter and shorter.
