If the global temperature keeps rising and all the glaciers melt, what will the world be like in a hundred years?

With the continuous development of human industrialization, greenhouse gases produced by human beings in all walks of life are gradually discharged into the atmosphere, which also leads to the intensification of global warming. With the global temperature rising, countries all over the world have also held joint meetings to discuss problems together. In the view of scientists, the influence of greenhouse effect is irreversible, and what human beings can do is to slow down the intensification of greenhouse effect.

The greenhouse effect cannot be changed. What will the earth become after the temperature of the earth continues to rise for a hundred years? 1. Glaciers melt and bacteria and viruses appear.

Although the annual temperature rise has not reached 1℃, after a hundred years' accumulation, the earth's temperature will inevitably change qualitatively. First of all, rising temperatures will lead to the melting of global glaciers, mainly in the north and south poles. When glaciers and frozen soil gradually melt, methane in them will be gradually discharged, which will accelerate the greenhouse effect again. Many glaciers in the world have existed for tens of thousands of years, including many ancient biological remains or viruses that have been sealed. When glaciers gradually melt, these bacteria and viruses will also come to the living environment of human beings, which will have a great impact on human society.

2. Sea level rise

In addition, melting glaciers will lead to sea level rise, ocean currents that affect the temperature in different places will also change, and extreme weather will occur frequently around the world, causing great damage to human life. When a large number of glaciers melt into the ocean, the sea level will continue to rise. According to scientists' calculations, if all the glaciers in the North and South poles and around the world melt, the sea level will rise by about 70 meters. We know that the topography of many coastal areas in the world is very low, and some are only a few meters. If glaciers really melt, most parts of the earth will be submerged by seawater, and even countries with high terrain will be short of food because of seawater intrusion.

Take the more developed cities in the world as an example. Cities such as London, new york and Tokyo are very low-lying, and will be submerged if the sea level does not rise by 70 meters. Some cities in the east of China will also sink into the sea. Even fast-growing cities like Shanghai and Shenzhen are still vulnerable to natural influences. Although sea level rise will not lead to human extinction, it will cause great losses to mankind and some problems will arise in the continuation of civilization.

3. The climate is changeable and extreme weather is frequent.

In fact, a large number of glaciers can not only breed abundant fresh water resources, but also reflect sunlight. The area of glaciers in the world is huge, and their existence also lowers the temperature of the earth. But when glaciers melt, some sunlight cannot be reflected, so the temperature of seawater will continue to rise. After a series of butterfly effects, volcanic eruptions become frequent and heavy rains will sweep the world.

This year's heavy rainfall has caused floods in many countries in the world, so when all glaciers melt, the intensity of rainfall will only be greater, and the threat of floods will be much stronger than this year's floods. There was heavy rainfall on the earth in prehistoric times, and it lasted for millions of years. At that time, most living things were extinct, so the rainfall that we are used to at ordinary times may also be a great disaster for mankind.

For marine life, the expansion of ocean area may be beneficial to them, but for terrestrial life or human beings, it is only a huge problem. Maybe by that time, land creatures will evolve to adapt to marine life again. In fact, in either case, it is a disaster for mankind. What we can do now is to protect the environment, reduce greenhouse gas emissions, curb the aggravation of the greenhouse effect and buy time for human development.
