2.The area of water has increased. Water evaporation is also increasing, the rainy season is extended, and floods are becoming more frequent. Increased exposure to flooding, increased severity and severity of storm impacts, and shortened dam lifespans.
3.Rising temperatures could melt snow and ice on the Antarctic Peninsula and the Arctic Ocean. Polar bears and walruses will become extinct.
4.Many small islands will be gone;
Global warming will lead to some natural disasters on the earth, that is, many people are also very afraid, after all, there is only one earth, if there are some natural disasters on the earth because human beings do not care for the environment, then human beings will have no way to survive on the earth.
Many people will think that global warming is caused by unreasonable natural activities of human beings, because human beings do not care for the environment, so the emission of carbon dioxide is rapidly rising, and it will also produce the greenhouse effect, but some scientists believe that although unreasonable human activities will lead to the emission of a large amount of carbon dioxide, but the emission of carbon dioxide is not enough to cause such a serious greenhouse effect, so there must be other reasons for global warming today.
In fact, there are many factors that contribute to global warming, such as the sun. Carbon dioxide, or some crustal movement in the Earth's interior, are the main causes of global warming, but obviously, if compared to the sun or the Earth's internal crustal movement. A rough search of human irrational activities and the emission of carbon dioxide are insignificant.
Scientists have found that the main reason for global warming in recent years may be that the movement of the earth's inner core is too frequent, which has led to the rise in the temperature of the earth's surface. If the Earth's core rock continues to move like this, then its temperature will continue to rise, and the temperature of the earth's surface will also rise, and it will be difficult for humans to survive.
Therefore, there are many factors that affect the global climate, although there are also some impacts caused by unreasonable human activities, but if all the blame is returned to human beings, it is actually very unfair to human beings, because if you want to make human scientific and technological progress, it will definitely cause some losses and destruction. Therefore, when human beings carry out social and scientific development, they should also pay attention to the protection of the ecological environment.

Anonymous users2024-02-05According to the education inquiry, the global climate has undergone significant systemic changes in the past 100 years, mainly in the following aspects:
1.Rising temperatures: The global average temperature has risen by about 1 , with the Northern Hemisphere Spring and Northern Hemisphere winters seeing the most significant increases.
2.Changes in the composition of coarse grinding gases: The increase in the concentration of greenhouse gases such as carbon dioxide, methane, and nitrous oxide leads to the enhancement of the greenhouse effect of the atmosphere and the increase of global temperature.
3.Sea level rise: Global warming has led to the melting of polar glaciers, ocean expansion, and water expansion, which has led to sea level rise and threatened coastal areas.
I think that China does not develop nuclear power for ten years or more is still the same, the difference is in China in the world is nuclear power countries or not, China's development of nuclear power is not entirely to solve the problem of power shortage in China, of course, to solve the power shortage is one of them, but the nuclear power plant in the construction process has a long construction period and high input costs, and the shortage of nuclear fuel is also a key problem, the nuclear power plant itself also has many problems such as immature technology and its own potential safety hazards; Another main reason for China's development of nuclear power is to demonstrate its national strength and show its scientific and technological capabilities to other countries, which is not only in nuclear power and other aspects such as aerospace, etc., which cannot be considered that China is showing off, this is only to prove that the Chinese are not slaughtered, China is also strong; The other is to make China's achievements in the application of nuclear energy available to the people and benefit the people; So I don't think China's nuclear power development will have a big impact on China, and if you don't develop nuclear power, you can develop other energy sources, such as hydropower, wind energy, tidal energy, geothermal energy, solar energy, etc., and there are still many hydropower energy in the Brahmaputra River and the Three Rivers basin that have not been developed. And they're all clean energy, it's renewable energy. The most important thing is that the great and industrious Chinese nation will be stumped by this question? >>>More
What happened to Jianwen is a mystery, when Zhu Di rebelled, Jianwen Emperor Zhu Yunwen disappeared like evaporation from the world. This is Zhu Di's big trouble, so Zhu Di sent Hu Hu to look for Zhu Yunwen, and this search has been more than 20 years. >>>More
It is extremely unfair that many people are just obsessed with the gender of Mr. Leslie Cheung's partner and the way he died. Everyone has the right to pursue love, and we have no need to be harsh. Putting aside these two points objectively, his singing skills and acting skills are undoubted, and he has made great contributions to the pop music scene and Chinese films. >>>More
At this stage, the question certainly seems absurd. But, throughout history, many things that people once thought were impossible have eventually happened; Many things that people once thought were morally unacceptable are eventually accepted. >>>More
During the Kangxi period, the people had enough food and clothing, and the treasury was full, which was enough to support hundreds of years, in fact, during the Qianlong period, the national strength was in a state of gradual decline.
