What effect does climate have on people's life and production?

With the increase of greenhouse gas concentration in the atmosphere, the impact of human activities on the atmosphere is mainly manifested in the increase of trace gases such as carbon dioxide, aerosol and water vapor in the atmosphere.

Irrigation, large-scale afforestation and reservoir construction can change the arid climate. Irrigation can make soil moist and change soil thermal characteristics. The evaporation of wet soil can make the air moist, and also make the daily difference between soil temperature and near-surface temperature smaller. Large-scale irrigation in arid and semi-arid climate region can not only change the microclimate of soil surface layer in irrigation area, but also increase the internal circulation of water in irrigation area, and the precipitation will increase accordingly.

Precautions:

From a global perspective, between 20 degrees and 30 degrees north latitude, due to the influence of subtropical high, the light and heat resources here are very rich, but the precipitation is relatively scarce. However, due to the numerous rivers and mild meteorological and climatic conditions in China, it is suitable for the growth of various crops, so it has become an area with a long history of Chinese culture.

Because of the vast mountainous areas and complicated climatic conditions in China, it also provides a certain space for the breadth of planting. There are many kinds of agricultural products in China, which enrich people's horizons and lives.
