The climate change of the earth has been accurately predicted. How is this achieved?

Divide the weather into many categories, such as blue sky, sultry air, humid air, fog and so on. And then establish relevant mathematical models according to the weather and climate types of each region. Through weather analysis, satellite meteorology and experience, let the computer calculate. When computers were not developed in the early days, it took a lot of time and manpower to calculate the weather in the next 24 hours through complex operations. But now, with the realization of high algorithm, the speed of the computer is greatly accelerated and it can be calculated.

Weather forecast is not only calculated, but also needs long-term observation and data recording. Because different time scales have different climate changes, climate change in some areas is closely related to the overall change of global temperature, so now countries cooperate with each other and share climate data, which makes the current temperature forecast more and more accurate. But now human beings only control the direction of large-scale weather forecast. If they want to be completely correct, it is very complicated to master the interaction between layers in the climate system, but to improve the accuracy, they can only continue to strengthen the development of climate system models.

Moreover, China's climate prediction has begun to develop into natural disaster prediction, which seems more urgent. Every year, many people in China die from natural disasters, coupled with the economic downturn. If we can accurately predict climate and environmental disasters, we can reduce the economic losses caused by natural disasters with a national GDP of 3% every year.

Only by systematically analyzing the earth's biosphere, especially its own evolution law and natural interaction from all angles, and combining theoretical data with mathematical models, can the accurate prediction of climate disasters be realized. If we can change from climate prediction to disaster prediction, we will have the initiative in the development of science and technology.
