What are the reasons why more and more scientists now feel that the earth is not suitable for long t

According to statistics, 15 in the world"Climate tipping points"Nine of them have already been activated, and some scientists believe that the collapse of human civilization is the most likely outcome. While this statement is somewhat exaggerated, one or more"Climate tipping points"can lead to irreversible climate damage, with huge losses and negative impacts on people and ecosystems. At the end of November 2019, in a review chapter published in the journal Nature, Professor Li Yining listed nine key points in the world, as well as Arctic sea ice and Greenland ice sheets, boreal coniferous forests, permafrost, Atlantic meridional overturning circulation, southwest Amazon rainforest, warm-water corals, polar ice sheets, and the southeast Wilkes Basin.

<> tipping point"is a familiar word that means that something will change from one state to another. For example, if water needs to be kept below 0 degrees Celsius to change from a liquid to a solid, then 0 degrees Celsius is a tipping point. In the official glossary of the United Nations Intergovernmental Panel on Climate Change (IPCC), tipping points are defined as:

In the context of the climate system, a tipping point is the threshold at which a global or regional climate changes from one steady state to another. "Once the tipping point is activated, the system cannot be restored to its original steady state.

When all"Climate tipping points"When activated, the Earth system may be reshuffled. Climate tipping points"The first attribute is irreversibility. Caused by global warming"Climate tipping points"and further cause a domino-like positive feedback effect that could push global forests, oceans, ice sheets, and more into an irreversible abyss of death.

In the context of global warming,"Climate tipping points"will be activated one by one, while"Climate tipping points"The effects produced by activation will react to global warming itself. For example, after global warming, as:"<> tipping point"One of the polar permafrost will gradually melt, and the organic carbon stored in ancient times will be released in the form of carbon dioxide, methane, etc., further exacerbating global warming. Intersections produce more intersections, which collide back and forth in global systems or subsystems, generating a large number of self-reinforcing positive feedback.

Once this process of collapse begins, more and more tipping points will emerge at an ever-increasing rate.

The environment of the earth has deteriorated. The earth's resources are getting scarcer. There are many extreme weather events on Earth. Several climatic boundary points have been activated. Glaciers are melting. Humanity in the future could suffer great catastrophes.

Because many people are constantly destroying the environment, and the earth's oxygen layer has also been destroyed, the earth's lifespan is also declining, the earth's ecological environment is also constantly bad, and the earth's sunlight is also weakening, so now more and more scientists feel that the earth is not suitable for long-term development.

In fact, whether the earth will be cold or warm in the future, it is just one kind of **. What we now know is just the tip of the iceberg of nature. Now scientists are also divided into two groups.

Some scientists believe that the Earth will be cooler in the future, while others still believe that the Earth will be warmer in the future. Of course, both of these scientists also have their own inferences. <

Before global warming, everyone thought that it was global warming. Because at that time it was speculated that global warming was more scientists than scientists. And now the winter in the north doesn't seem to be as cold as it used to be.

The reason given by this part of the scientists is because the development of industry produces a large amount of carbon dioxide. Carbon dioxide is the main culprit in warming temperatures. And now the area of the forest is gradually decreasing.

The more forests there are, the more oxygen there will be, and the more carbon dioxide will be. These are the reasons why scientists believe that global warming will occur. <>

As for the arguments given by scientists who think of global cooling, the arguments given by scientists who previously thought of global warming were that the data they collected were only data from the periphery of cities, so they didn't think the data was representative. These scientists who believe that global warming is looking at the planet as a whole and the temperature. They observed that temperatures in the Northern Hemisphere were generally elevated.

But temperatures in the Southern Hemisphere are falling. If you look at the whole earth, the temperature of the earth is decreasing every year. The overall temperature of the earth is gradually decreasing.

Scientists who support the global warming narrative take into account the mostly human-caused effects on the planet. Scientists who think of global cooling are considering changes in the planet itself. While both types of scientists have their own reasons, it is not known what will happen in the future.

What they think is just speculation. Because human beings have so little understanding of nature.

Because nowadays, with more and more greenhouse gas emissions, the earth has warmed up. It may begin to enter the Xiaoice Age over time, so the world will likely get colder.

At first, scientists believed that the industrial development of human beings, the destruction of forest plants, and the increase of carbon dioxide led to the warming of the planet. Later, scientists artificially said that human activities would only temporarily affect the temperature of the earth, and the temperature of the earth would gradually decrease.

In the past, the rapid development of industry and the massive population surge led to excessive carbon dioxide emissions, which led to the thinning of the ozone layer, and the sun's radiation to the earth will increase, which is why it is said that global warming.

The temperature change of the earth itself has a certain regularity in a certain period of time, which has been concluded by scientists many years ago, and at present, scientists have only carefully studied the previous conclusions, and then the data has been clarified. Therefore, the temperature change cycle of the earth is a very natural climatological and astronomical phenomenon.

Because of the unstable weather conditions this year, there is still a lot of cold air in many areas, so it will not warm this year.

Scientists believe that the earth is about to cool, and the reason for the pause in global warming is the decrease in the amount of sun, which will cause the earth's temperature to cool, and it is likely to enter the Xiaoice Century.

Scientists believe that the Earth is about to cool and the reason for the pause in global warming is because of the decrease in sunspots, which will cause the sun to release less heat energy.

Because scientists believe that the ice and snow in the Antarctic and the Arctic are gradually melting, and if their snow and ice melt, it will make the global temperature very cold.

Scientists say that since the earth can cause significant changes in temperature and weather due to the cooling of the outside world, can this very small period intervene or prevent global gradual warming?

Are humans the only living beings on Earth?

I thought that human beings are not a lonely existence in the universe, there are many other lives in the universe, when they really move towards the universe, they completely refresh their previous cognition, the universe is not as lively as imagined, but a dead silence, no life at all, it seems to have no end, like a silent island, human beings are eager to find their companions in this place, and they have been looking for so long without success. This makes people wonder, is it true that only human beings are the only living beings in the universe? If there are other life forms, why haven't they appeared yet?

The octopus is not an Earth creature, it comes from an alien planet? We've misunderstood it for a long time!

Although humans have not found any traces in outer space, they have found a questionable creature on Earth, which is the well-known octopus. The octopus is a mollusk with many tentacles, and several biologists have put forward the idea that the octopus may not be a creature on Earth, but that it may have come from an alien planet and followed the ice comet 570 million years ago to Earth. After years of evolution, breeding has only now had a new form, why is it said that the octopus comes from an alien planet?

What are the differences in the anatomy of octopuses?

The octopus has a very different body structure from other animals, it has three hearts, and these three hearts have a clear division of labor and each has its own function. The most unforgettable thing is that it has 8 nerve-filled brachiopods and has a strong adsorption force, and if the octopus is kept in a sealed bottle, it can use its body to open the bottle, which has aroused the curiosity of many scientists.

In addition, it has two memory systems, one for the brain and the other for its tentacles, and having 8 tentacles means that it can be multi-tasking. The most important thing is that the octopus has a concept of thinking that ordinary people cannot understand, it can not only solve puzzles that humans cannot break through, but also can walk on two legs underwater.

While it has a lot of skills that creatures don't have, it also loses something, and its evolution is much slower than normal creatures. Seeing that it has so many special skills, more and more scientists believe that it is an alien creature. As for whether it is or not, there is no strong enough scientific basis

Octopuses may be a little strange to us, not very often seen, sometimes only on TV, when we watch TV, we should all know that octopuses are soft and have eight legs. It lives in the ocean, so it can't be seen very often. In fact, everyone is very confusedWhy do more and more scientists believe that octopuses may not be Earth's creatures?

Because the octopus has very peculiar physical characteristics, scientists think that it is not a living creature on earth.

Octopuses have a lot of strange characteristics, so I'll tell you about them in detail. The octopus is soft all over its body, and although it has eight legs, its legs are also soft. So he moves all by the attraction of his legs.

Everyone knows that we humans and most other animals have one heart, but the octopus has three hearts, which is very peculiar. The number of genes in humans is about 25,000, but the genes of octopuses are a staggering 330 million. Moreover, some of the octopus's genes can also be recombined on its own, so it has good adaptability to the environment.

I don't know if you have carefully learned about octopus in books or TV, its food is usually shells and some crabs and the like, although their hands and feet are very soft, but they eat shells are broken with their hands and feet, these are the peculiarities of octopus, so scientists will think that it is not a creature on earth.

In fact, not only octopuses, but many other animals and plants have their peculiarities, but none of those animals are said to be creatures that do not belong to the earth. It is precisely because of the fact that there are so many strange things about the octopus's body, and then their way of life is also very strange. Until now, scientists have not fully understood the octopus.

It is because of these special circumstances that scientists believe that octopuses are not creatures on Earth.

Because the octopus's blood is blue and its appearance is peculiar, more and more scientists will think that the octopus may not be a living creature of the earth.

The octopus is a sea creature and a type of seafood. People often eat octopus. Actually, the octopus is what people call it, and the squid is also known as the octopus.

So why are more and more scientists believing that octopuses may not live on Earth? Actually, it has to do with the physiology of the octopus. The structure of the octopus is very special.

It also has three hearts, two departments for blood** and one for the entire body. It has 8 very many claws.

Because octopuses have very developed brain cells, even far more than humans, and have the ability to change their own genes, it is likely to be an alien creature.

Scientists in the field of astronomy and outer space research have two main views on whether human beings should leave the earth: one is that it is better for human beings not to leave the earth, but to stay on the earth to seek sustainable development, and should not extend their hands too much to outer space; The other is that human beings should leave their homeland on earth, actively explore outer space, look for traces of extraterrestrial civilizations, and plan for the further development of mankind. At present, the two views are at odds, the main reason is that the current level of science and technology is limited, and there are too many unknown areas in outer space, so scientists can only make conjectures and judgments based on their existing knowledge, which naturally arouses the thinking and reverie of the entire human community.

The famous physicist Stephen Hawking also expressed his opinion on this, he believes that human beings should not easily send signals into outer space, nor can they respond to various signals from outer space. Because he believes that there is a great possibility of a higher-level alien civilization, once he learns that there are abundant resources on the earth, he will inevitably come to the earth, and it will be a disaster for mankind at that time.

This idea is similar to the law of the dark forest in Liu Cixin's "Three-Body Problem", which states that if a certain cosmic civilization exposes its spatial coordinate position in the universe, then it will inevitably be hit by other higher civilizations, which will be a disaster. However, Hawking also proposed that human beings should find another home as soon as possible, believing that human beings' excessive exploitation of the earth's resources has disrupted a certain balance, and it is likely to lead to extinction due to some kind of disaster. Such a statement may sound creepy, but more scientists and people are optimistic.

To sum up, it can be seen that the existing scientific means cannot prove and ** the future of the earth, for more people, the earth is the home of mankind, is the mother of mankind. What human beings can do at present is to conduct in-depth scientific research to understand themselves, the earth, and the universe, and at the same time need to re-examine the relationship with the earth so that human beings can achieve better development.
