What will the weather be like after the earth?

The future climate, or 2 1 century climate, is first related to the emission of greenhouse gases, especially carbon dioxide. According to the future economic development and different environmental protection measures taken in the next few years, the climate will have different conditions. It is predicted that the concentration of carbon dioxide in the atmosphere will double by the end of this century. The consequences of environmental pollution are mainly manifested in three aspects: the increase of average temperature, the disturbance of atmospheric circulation and climate stability.

If carbon dioxide doubles, the increase of greenhouse gas concentration will enhance the greenhouse effect in the next few decades, and the average temperature of the earth will continue to rise. If the concentration of carbon dioxide in the atmosphere doubles by the end of this century, the average temperature of most land will rise by 4~5℃.

In 2030, the global average temperature will rise by 1~2℃. If the concentration of carbon dioxide increases rapidly, the global average temperature will rise by 1~2℃ by 2030. By 2080, the average temperature may rise by 1.5~3℃, and the Mediterranean region may rise by 3.5~4℃. The increase of average temperature not only makes the daytime hotter, but also makes the heat wave more intense and lasting, even in autumn and winter.

The deep-water conveyor belt may be blocked near the Arctic Circle, and the rising temperature may lead to the melting of huge polar ice floes. In some parts of Greenland, the ice is thinning at a rate of 40 cm to 60 cm per year. The influx of fresh water into the Atlantic Ocean may lead to a sharp decline in seawater salinity in the next few decades. The decrease of salt content may affect the deep-water layer in the North Atlantic, block the deep-water conveyor belt in the North Atlantic and prevent the warm current from reaching northern Europe. Due to the lack of warm current, the overheating caused by the greenhouse effect may be partially curbed.

As the ocean becomes hotter and hotter and the sea level rises, the rise of the earth's temperature will have a great impact on the ocean, because the water on the ocean surface will be hotter than it is now. In this way, typhoons will become more frequent and intense, and will extend to the marginal areas of temperate zones. At the same time, some mid-latitude closed basins, such as the Mediterranean, may become veritable tropical oceans. By the end of this century, if the concentration of carbon dioxide doubles, the sea level will rise by 10 cm ~90 cm. This is partly because of the melting of polar ice and partly because hotter water will take up more space. The geographical state of the coasts of all continents will be disrupted, and coastal metropolises such as new york, Miami, Bangkok and Venice will be submerged by seawater.

The movement of the high pressure center and the stronger greenhouse effect also mean that there will be more energy in the atmosphere. The great circulation of air will be interrupted, and large centers of high pressure and low pressure, such as the high pressure in Azores and the cyclone in Iceland, will change their positions. According to the speculation of British scientists, the winter rainfall in Europe will decrease by 1mm on average every day in the middle of this century. Atmospheric phenomena will become more intense, tornadoes in North America will be more frequent and destructive, and storms will hit temperate regions more frequently.

With the destruction of atmospheric circulation, more violent rainfall and more severe drought will also change their laws. El Nino will become more frequent and intense, and monsoon will bring more rainfall and cause floods. However, due to the lack of rain, the dry season will last longer, making fires more frequent and sandstorms more frequent.

Another consequence of more unstable climate and increased atmospheric energy will be climate instability. The phenomenon of swinging around the average will increase, and extreme natural phenomena will become more frequent and unpredictable. People will feel that the climate often changes from extremely hot to unseasonably cold, or it suddenly rains cats and dogs when the sun is shining.

The future climate we describe here is really depressing, but it is not something that humans have the ability to change, it depends on the choices they make. These choices are to consider the environmental conditions of the earth more without affecting economic development. At present, there are many technologies to control pollution, but more importantly, we must actively use these technologies.
