Preface
After thousands of years of development, human civilization has entered a new era.
Now we are immersed in the beautiful life brought by scientific and technological progress.
But at a time when we are enjoying such a good life, there are scientists who predict the time of human extinction.
So, has humanity really come to the point of extinction, and how can humanity prevent such a thing from happening?
Calculate the time of the extinction of the human race
In fact, there are many prophecies about the demise of mankind, such as the Mayan prophecy, or the Hawking prophecy.
And many film and television works also tell the scene of the end of mankind and the end of the world.
But after all, these are all guesses of human imagination and speculation.
But with the development of science and technology, the results of scientific research are more convincing, and there is such a paper in the journal Nature Geoscience.
Southern Metropolis Daily (2023-09-26) published an article titled "Scientists Calculate the Date of Human Extinction, When the World Faces Extreme Heat and High Humidity".
It is a conclusion reached by a team of British scientists through simulation calculations on a large computer.
That is, after 250 million years, the earth is no longer suitable for human life, and human beings will be extinct at that time.
According to the paper, because the Earth is also in constant motion, all the continents on the Earth will move together in 250 million years.
By that time, there will be only one "supercontinent" left on Earth.
And the living environment of this continent will also become very harsh, by this time, the temperature on this "supercontinent" may reach more than 40 degrees Celsius.
According to the researchers' calculations, the location of this "supercontinent" is mainly distributed in hot and very humid areas.
So at that time, the environment on Earth will be hot, as if you are entering a "steamer".
Not only that, but researchers say that by then the concentration of carbon dioxide on Earth could be more than twice as high as it is today.
In such an environment, it is difficult for humans and a large number of mammals to adapt.
It can be said that it is basically unsuitable for human habitation and survival, so human beings will slowly become extinct.
However, at that time, not only will we face a high temperature and humidity environment, but also face the threat of life caused by volcanic eruptions.
The large amount of carbon dioxide produced is released into the air, which will not only lead to a further increase in global temperature, but also affect the survival of human beings.
But after all, 250 million years is still a bit too far for us today.
However, at present, volcanic eruptions are frequent, and the harm to the world and all mankind is also enormous.
Volcanoes erupt frequently
The researchers in the United Kingdom say that after 250 million years, when the plates of various continents came together.
In such an environment, the frequency of volcanic eruptions will further increase, and the harm caused by volcanic eruptions to human beings is unimaginable.
Not only is the magma flowing out at extremely high temperatures, but there is no grass everywhere it goes.
There is also volcanic ash produced by volcanic eruptions, which will bring great harm to the earth's temperature and living environment.
In 2022, it seems that the "high-frequency" period of volcanic eruptions has ushered in.
Many volcanoes around the world are unusually active.
Guangming.com (2022-12-30) reported on "How are many volcanoes active in the world!How do volcanic eruptions stir up the global climate?".
In 2022, Mauna Loa in Hawaii erupted for a long time, and it is currently the largest active volcano in the world.
The magma flowing from the volcano is more than 1,000 degrees Celsius, and it has spread as the mountain continues to spread, and it has even approached the highway in Hawaii.
And the volcano has been erupting since November 27 and shows no signs of stopping until December 1.
People's Daily Online (2022-11-30) reported on "Lava Flows! Hawaii Mauna Loa Volcano Erupts".
Not only that, but Kilauea, also on the island of Hawaii, was also in the eruption phase at this time.
Also in December, Mount Semeru in Indonesia erupted.
Although it is an active volcano and has erupted over the years, this eruption triggered the country's highest level of defense alert.
One can imagine how damaging the volcanic eruption was.
Similarly, in December, the Stromboli volcano in Italy spewed out a large amount of magma.
The eruption also caused a tsunami of more than 1.5 meters.
It can be said that in 2022, volcanoes around the world are "piling up" to erupt.
But at a time when global temperatures are rising, some people say that volcanic eruptions will bring about a decrease in global temperatures, but what is going on?
About 75,000 years ago, there was a supervolcanic eruption, located in Sumatra, Indonesia, but the impact of this eruption has spread to the South China Sea on the mainland.
The eruption also dropped the world's temperature by an average of 5 degrees Celsius, and the temperature dropped by about 15 degrees Celsius in the places where the cooling was most severe.
But it's not the ash that's affected, it's the sulfur-containing gas produced by the volcano after the eruption.
Under the action of the stratosphere, it will move to various places in the world, and it will stay in the world for a relatively long time, so the impact on temperature is also very large.
Although the eruption caused a decrease in global temperature to some extent, it also led to a decrease in rainfall, which indirectly affected global temperature in other ways.
However, it is still unknown whether the eruption of multiple volcanoes in 2022 will have an impact on global temperatures.
However, extreme weather on the planet is also increasing.
On the evening of April 27, extreme weather such as a tornado occurred in Guangzhou, accompanied by a super hailstorm.
Guangming.com2024.04.28 reported on "The strong tornado in Guangzhou has killed 5 people and injured 33 people!" At the time of the incident, it was suddenly dark, and the hail was like an egg and a big ......".
As of April 28, this extreme weather has caused bad news that five people have been killed.
Not only that, at the moment when we are about to enter May, we are about to usher in the beginning of summer, and many regions in Hebei have ushered in a wide range of snowfall.
Even some areas have a snowfall of 32 centimeters, and traffic in many places has been affected to varying degrees.
CCTV News published an article on 2024-4-29 titled "Snowfall in Many Places in Hebei Returns to Winter One Night".
epilogue
Although British scientists have calculated that humans will be extinct in 250 million years.
But at the same time, they also say that their predictions are not absolutely accurate.
However, it is also emphasized that some human activities may even accelerate the pace of human extinction, which may be extinct 250 million years ago.
Jimu News (2023-09-27) reported on "Extreme heat may extinct mammals in the next 250 million years".
