I! Pretending to Be Reborn, Director of Doomsday Hoax

This means that everything recorded above should be based on rigorous experimental results, and there is evidence to rely on!

According to this research report,

The blue star is getting dimmer, and, due to climate change, warming oceans have reduced bright clouds above the blue star, which in turn reflects less light into space.

"What's the fuss about that?"

Zhao Xiaolu is not worried about this.

Before, their Meteorological Bureau, including climatologists around the world, were worried that global warming would bring disaster to Blue Star,

Now this problem doesn't exist at all.

Twenty days later, it was the Little Ice Age.

Ten months later, it was the sun that went out.

Humans wish that Blue Star would be warmer!

"Previous researchers had hoped that a warming planet might produce more clouds and a higher albedo, which would help slow the planet's warming, but now, according to this study, that may be the case," the researchers said. In contrast, blue stars would warm more severely.

"However, ten months later, the sun will go out again. Does this mean that the blue star will experience a terrible roast before the sun goes out?"

Zhao Xiaolu was taken aback.

He hadn't thought of this possibility just now!

If the bright clouds above the blue star disappear,

A large amount of sunlight is projected onto the blue star, which will cause the blue star to heat up violently in a short period of time!

This is actually quite a disaster!

The global high temperature will melt the glaciers in the north and south poles, and the sea level will rise.

Cities along the coast may be submerged.

After that, the sun goes out and the extreme cold comes.

The seawater that flooded the city will condense in an instant! !

This can cause greater losses and more serious harm than direct cooling!

Zhao Xiaolu's expression became serious instantly, and he checked the document carefully!

The global dimming mentioned above does not actually mean the darkening seen from the ground, let alone the darkening of the sky and the sun.

Rather, the Earth is darkened as seen from space!

There is a key concept here called albedo, which is an important term in satellite remote sensing.

It refers to the ability of a surface to reflect light of a certain wavelength,

For example, the albedo of Venus to sunlight is 0.7, which means that when sunlight hits the surface of Venus, 70% of the light will be reflected to other places, and only the remaining 30% will be absorbed by Venus.

In fact, the issue of "sun dimming", which is similar to global dimming, has long entered the field of vision of climate scientists.

It means that the earth's surface receives less sunlight, and the average brightness of the sun seen from the ground has weakened by about 4%.

The "global dimming" in the literature refers to the view of the earth from space, with different positions, but it is not completely contradictory.

even,

The conclusions of "global dimming" and "sun dimming" are consistent.

Looking at the earth from space is the infrared radiation emitted from the upper atmosphere of the earth and the reflected sunlight.

What is seen on the ground is the sunlight reaching the ground.

What can cause both to weaken is the increase in radiation absorbed by the atmosphere and clouds in between.

And these extra absorbed radiation is the energy source that causes global warming.

Blue Star's climate system is a very complicated dynamic balance system.

The equilibrium temperature when the input and output energy of this system is basically the same is the average temperature of the surface of the blue star.

The energy input into the blue star climate system mainly comes from sunlight, that is, short-wave radiation, mainly in the ultraviolet and visible light bands.

The output energy comes from the thermal radiation of the blue star itself, that is, long-wave radiation, mainly 3.5 in the infrared band.

According to Stefan Boltzmann's law, the intensity of thermal radiation produced by an object is proportional to the fourth power of the thermodynamic temperature.

therefore,

According to the average temperature of the blue star's surface, the radiation intensity emitted by the blue star to outer space can be obtained.

Solar radiation is also calculated in the same way.

However, since the sun is far away from us, the solar radiation emitted from the surface has been attenuated a lot when it reaches the blue star, so the two can basically maintain a balance.When the albedo of the earth's surface increases, it means that the earth's surface reflects more sunlight. If we look at the earth from outer space, we will feel that the earth has become brighter.Conversely, a decrease in surface albedo would cause the Earth to appear darker from space.

And the result of this literature study is that the blue star has dimmed.

There are many reasons for the decrease in surface albedo, including shrinking glaciers, decreasing cloud cover, increasing smog, and so on.

The direct consequence of the decrease in albedo is that the solar energy absorbed by the earth has become more, so in order to achieve a new energy balance, it is necessary to heat up the earth's surface and emit more heat radiation,

It can be said that "global dimming" is an inducement of "global warming".

Sunlight reaching Earth can be absorbed by atmospheric molecules, by cloud and aerosol particles, and by the ground.

When glaciers melt, the exposed sea water or land absorbs sunlight more easily than glaciers.

Many aerosols can also absorb sunlight, black carbon aerosol is even more powerful.

however,

These are all contributing factors to "global dimming"!

If "global dimming" intensifies, it may push the limits of the internal adjustment capacity of the climate system.

For example, the continued shrinking of glaciers will worsen global warming, and global warming will in turn accelerate the melting of glaciers, thus forming a vicious circle until all glaciers melt...

The Blue Star Physics Federation in Berry Country is obviously also aware of this problem, and only at this juncture, published this research report.

The researcher looked gloomy, and said: "If there are no other factors to adjust, our climate system will move towards an out-of-control greenhouse effect. The possible destination can refer to Venus...

At this time, if there is a certain factor that the higher the temperature is, the more it can suppress the warming, and form a negative feedback, the impact of 'global dimming' can be weakened!

I'm thinking, will this Little Ice Age be a self-protection mechanism of Blue Star, through extreme conditions, to break this vicious circle? "Zhao Xiaolu's face was very strange.

Blue Star's self-protection mechanism?

This is a bit too unbelievable.

He frowned and said, "Don't take humans too seriously...

"Although I am a climatologist, I am also a geologist.

"I have studied the evolution of the environment and climate for hundreds of millions of years, and I finally understand that it is not a question of human beings saving the blue star, but a problem of human beings saving themselves.

"Blue Star doesn't need humans to save it. Sometimes the temperature is tens of degrees higher than it is now, and the concentration of carbon dioxide is tens of times higher than it is now. There are even various planetary impacts, horrible biological extinctions, and ice ages... …

"Blue Star never perishes!

"The only species that is destroyed is man himself.

"Even if Blue Star really has the ultimate self-protection, it will not be activated because of a global dimming and global warming caused by humans. It is like a lice jumping on you, you will not burn yourself with a flamethrower Same!"

The researcher was silent for a long, long time.

Zhao Xiaolu opened the drawer and took out a report from it.

He waved his hand, asked the researcher to open it and check, and said:

"I've been working on this for a long time, the Global Climate Panel, published a secret document years ago, the largest and most important report on climate change ever!

"However, because the content in it is not very optimistic, spreading it may cause unnecessary panic among many people, so only a few high-level climatologists, leaders and other decision-making people in various countries know about it.

"Now, with the advent of the Little Ice Age and the era of extreme cold, the confidentiality level of this report has been lowered. You can see how pessimistic the situation of human beings is!" An ominous premonition hangs over my heart. .

share report

Chapter 120 The vast universe is the only way out for human beings!

Zhao Xiaolu was in a very gloomy mood.

The living conditions of human beings, even without the Little Ice Age and the Extreme Cold Era, would have been very severe! "This is a secret report on global extreme climate records." Zhao Xiaolu said.

Bao Yongfeng opened the document that was once dubbed the highest confidentiality level of the Global Climate Change Panel.On it, there are signatures of [-]+ five countries...

This Bao Yongfeng was deeply shocked at the moment,

It turns out that the country has been planning secretly for a long time?

The largest and most important report on climate change in human history shows that

Since the nineteenth century, humans have burned fossil fuels for energy, causing global temperatures to rise [-]°C above pre-industrial levels.

And, in the next few decades, it will continue to heat up!

Under this doomed trajectory, extreme weather around the world will appear more frequently and significantly...

The report has a total of three thousand more than 500 pages.

There have been more and more extreme climates in recent more than 20 years.

Not to mention other years, just last year.

Last summer, due to torrential rains, floods hit several states in Tianzhu, and devastating flash floods broke out in Gukeguo, Helan and other areas, causing thousands of deaths and tens of thousands of missing people in the west of Ouzhou. Thousands of families are stranded and homeless.

Streets become rivers.

Shops and houses collapsed and towns and villages were flooded.

The provinces in the middle of the Dragon Kingdom experienced the heaviest rainfall in the past 1000 years, resulting in severe floods in the city, and the streets became turbulent rivers, resulting in the death of more than 300 people!

Flooding caused by record rainfall flooded the entire city, vehicles were washed away, subways were submerged, people were trapped in subways and carriages, suffocating to death...
