With frequent high temperatures and frequent floods, why do scientists think that the earth's climate is close to the critical value?
With the rapid development of science and technology, people pay more attention to the environment besides technological innovation. The earth is the home for human survival and the foundation for human survival. In recent years, all parts of the world have developed rapidly before the restoration, which has caused irreversible damage to the environment. However, the global temperature is still rising, and the trend of global warming has not been alleviated and controlled.
some people may wonder, isn't global temperature rising a good thing? In this way, people don't have to be attacked by the cold. Of course not. Global warming will cause a series of reactions, which will lead to the decrease of species and the deterioration of the environment.
Global warming will melt the Arctic glaciers, which will cause the sea level to rise, which may cause some coastal areas to be submerged and the land area will be drastically reduced. Moreover, glaciers are fresh water resources on which we live. If all of them melt into sea water, there will be less and less water we can drink.
The increase of carbon dioxide will reduce the oxygen in the sea, thus disrupting the balance of the benthic biological chain and causing species extinction. In the history of biological evolution, there was a species extinction, which was caused by the lack of oxygen content and the increase of carbon dioxide content in seawater. Global warming increases the frequency of extreme weather. In 221, the flood disaster in Zhengzhou was very serious, and the sandstorm in the north and northwest was also very serious. All kinds of extreme weather came one after another, which made everyone worry about what happened to the earth.
Global warming will not only affect the environment and make human survival more difficult, but also make the survival of living things more difficult. Needless to say, marine life, if there is less and less oxygen in seawater, the biological chain on the seabed will be broken immediately, and the creatures on the seabed will suffer an unprecedented extinction. Life on land can't run away, and life in tropical areas near the equator can't stand the high temperature. If I make some animals that can't adapt to high temperature today, it may become extinct.
according to the research of scientists, there is only one critical point of climate, and once it exceeds this critical point, the global climate system will collapse. The first collapse of climate system indicates the collapse of the earth's environment. Immediately after the appearance of extreme weather and the collapse of the biological chain, the living space of human beings has shrunk dramatically. The strength of human beings is very small in the face of nature, and various disasters will drastically reduce the number of human beings. The decrease in the number of human beings will make human civilization retrogress, and the level of science and technology may retrogress. At that time, the extinction of human beings is an irrefutable result.
And human beings are very close to that critical value. In order to enable human beings to survive healthily before the end of the earth's life, it is urgent to protect the environment and curb the global warming trend. After all, with our current level of science and technology, there is no way to make all mankind move to another planet, and we haven't found a planet suitable for living yet. If global warming intensifies the destruction of the earth and our technology has not reached its peak, then mankind can only do nothing.
