Will it get hotter in the future

The Northern Hemisphere is experiencing an Eocene-Paleocene era climate in the summer of 2022!

The Arctic is so hot that it wears short sleeves, several rivers are drying out, and temperatures are setting new record highs, all signs are pointing to a truly hotter and hotter planet.

However, a NASA study shows that the Earth is gradually moving away from the sun.

In other words, the future Earth will not be so hot, the Earth will slowly become cold. So, will the Earth really be cooler in the future?

The world is in drought everywhere

A hotter Earth

The summer of 2022 is destined to be recorded in the history books of mankind. This year in the northern hemisphere really explains what it means to be hot.

Several countries in Europe set their own records for heat over the past century, rivers dried up, revealing the "Hunger Stones" left behind by their predecessors, and even German warships from the Second World War.

According to Eurostat, this hot drought in Europe is the worst in 500 years.

Throughout 2022, Europe lost 40% of its water, and who remembers that in 2021, Europe was still flooded.

Why has the planet gotten so hot?

The first reason must be known to everyone, the greenhouse effect caused by carbon dioxide.

Since mankind opened the door to industry, the Earth's temperature has been on the road to rise.

From the first industrial revolution to the first decade of the 21st century, the average temperature of the Earth has increased by 1°C, and the global average temperature in 2022 is more than 1.5°C.

The development of industry has intensified the use of fossil fuels, and humans have released distant carbon into the atmosphere.

Industrial revolution

Another reason for the Earth's warming is the end of ice ages and the beginning of climate change.

Just as Europe was experiencing a 100-year heat wave, the Arabian Peninsula, which has always been known for its heat and aridity, experienced a 100-year rainfall that irrigated the desert into a sea of sand.

When the camels saw the bubbling water, they were dumbfounded, when did they get so much more water at home?

12,000 years ago, the Earth ended a major ice age that lasted for more than 2 million years. The end of an ice age lasts for a long time, from tens to hundreds of thousands of years.

Earth's last ice age

That is, according to the Earth's original plan, it was supposed to get warmer and warmer.

However, human carbon emissions have brought this end period forward, perhaps to 2022.

The year 2022, when we feel hot, will probably be the coolest time in the next 10 years.

Does it sound so desperate that our suitable temperature will never return?

It seems that, not without a turnaround, NASA announced that our planet is moving away from the sun, the sun will reach the Earth's surface less and less heat.

The Earth will get hotter and hotter

Moving away from the sun

There is a term in astronomy called "1 astronomical unit" (A.U.), which indicates the average distance between the Sun and the Earth, using it to visually express the distance of other planets from the Sun.

The current 1A.U. is equal to 149,597,870 kilometers, which can be approximated as 150 million kilometers.

NASA, on the other hand, says that this figure may change in the future, as it is getting larger and larger.

Why does the Earth move away from the Sun and does it really want to wander?

There are 3 main reasons for moving away from the sun, the first is the expansion of the universe, the second is the growth of the solar system itself, and the third is that the mass of the sun is being cut down.

The Sun, the Earth and the Moon

Let's look at the first reason cosmic expansion. Because of the Big Bang 14 billion years ago, the universe has been in a state of expansion, because the energy generated by the explosion is like the gas provided by blowing up a balloon, driving the space of the universe to keep getting bigger.

Therefore, no matter what the relationship of the objects in the universe are, they will get farther and farther apart from each other.

An important evidence of the expansion of the universe is the redshift of electromagnetic waves, simply because the expansion stretches the electromagnetic waves, making the visible light inside longer wavelengths, shifting toward the red side, the original visible light is stretched into infrared.

On the contrary, if the universe is shrinking, then there will be a blue shift, that is, the wavelength of visible light is shortened, shifted towards the blue, violet side, and eventually shrunk into ultraviolet.

Cosmic expansion

The second reason is the growth of the solar system itself, which is about 4.6 billion years old, a relatively young existence in the universe.

Therefore, the solar system itself is still "growing" and expanding outward at the edges.

The first solar system was a nebula, which was obtained by fusion reactions through constant aggregation. The initial solar system was very small, with many objects crowded together, and many impacts took place.

The Earth was not in the habitable zone of the Sun when it was first born, but rather the distance of Mars was habitable.

Later, as the solar system grew, Mars was moved out of the habitable zone and the Earth took its place.

The solar system is still growing

The third reason is that the Sun itself is losing weight.

The Sun is the heaviest being in the solar system, occupying more than 99.99% of the total mass.

The most abundant substance in the sun, however, is hydrogen, and the sun's incandescence is not hydrogen burning, but hydrogen atoms undergoing nuclear fusion reactions.

The sun consumes 600 million tons of hydrogen every second through nuclear fusion, which means that the sun leans 600 million tons every second.

The sun's gravitational pull comes from its enormous mass, and mass reduction weakens the bonds it has on the objects surrounding itself.

Under the influence of inertia, the bodies of the solar system will have larger and larger orbital radii, that is, they will gradually move away from each other.

So what happens when the Earth moves away from the Sun?

The hydrogen on the surface of the Sun is fusing

Consequences

As the Earth moves away from the Sun, it receives less and less heat from the Sun, as can be seen from the planet Mars.

Although Mars has the word "fire" in it, it is very cold, with an average surface temperature of -61°C, equivalent to the South Pole on Earth.

However, Mars is so cold because it does not have an atmosphere, which can be insulated to some extent, especially if there is carbon dioxide or methane in the atmosphere.

The amount of carbon dioxide in the atmosphere should not be too much either, otherwise it would be a super hot planet like Venus, hotter than even Mercury.

Mars is very cold

When the Earth is far from the Sun, it will stay the same for a long time because of the insulation effect of the atmosphere, and the temperature will not drop significantly.

It is only when the Earth is far enough away from the Sun to receive insufficient energy to reach a habitable temperature that the Earth begins to change toward cold.

This process will continue for hundreds of millions of years or even more than a billion years, and the cooling will be gradual, not sudden, which can give life on Earth a long time to adapt.

Therefore, it is almost impossible to slow down the current heat wave in the Northern Hemisphere and future warming by moving the Earth away from the Sun.

Until then, humans will have to endure a long period of heat and drought.

So is the heat wave of 2022 a sign of a disaster?

After the Earth becomes colder

Where does humanity go from here?

For the Earth, this is not the first time it has gotten so hot, nor is it the first time it has ended a major ice age.

To be frank, getting colder or warmer is a basic operation of the Earth, a means of self-regulation.

The Earth was once a ball of fire, the Earth has also become a ball of ice, cold or heat will indeed cause environmental changes to make a large group of organisms extinct, but cold and heat will never make life completely erased from the Earth.

The fear of mankind is that life will find a way to live, but not so much man.

The Quaternary Ice Age

As the saying goes, there is a representative of an era, and humans have been the representative for more than 2 million years, and the representative of the next era, perhaps, will change the protagonist.

There is no eternity, even the dinosaurs that stretched 160 million years did not do.

Environmental change is complex, it is never just a single situation, such as this heat wave, some places are drought, but some places are flooded, a vivid interpretation of what is called "drought death, flooding death".

Therefore, for human beings, the earth has not become uninhabitable in its entirety, but only partially.

Flooding in the desert

There is a place where the mulberry field becomes the sea, then there is a place where the sea becomes the mulberry field.

Just this process will have many chain reactions, and it becomes crucial whether human beings can successfully survive this wave of warming.

According to the past history of the Earth, global warming will make the high latitudes are growing rainforests, the glaciers at the poles melted to just a little or even directly the entire planet without a trace of ice.

Mankind is facing the problem of rising sea levels, the reduction of land area, where should mankind go?

As for the Earth in leaving the sun, not to mention that humans can not prevent this from happening, and even if it happens, it will take hundreds of millions of years to experience.

Sea level rise

According to the rapid development of human beings, by that time, I am afraid that humans have long ceased to live on the Earth.
