What effect does the weather change have on us? What's the role?

Climate change has many impacts and functions on us: health impact, agricultural and food output, water resources management, ecosystem impact, energy demand and economic impact.

1. Health impact: extreme weather conditions (such as high temperature, cold, rainstorm, etc. ) has a negative impact on human health, causing diseases and discomfort. For example, hot weather may lead to health problems such as heatstroke and dehydration; Cold weather increases the risk of colds and respiratory infections.

2. Agriculture and grain output: Weather changes have an important impact on agricultural production and grain output. Extreme weather events such as drought, flood and hail lead to crop yield reduction and loss, thus affecting food supply and price stability.

3. Water resources management: Changes in rainfall and drought conditions will affect the availability of water resources. The lack of water resources in drought period leads to water crisis and irrigation difficulty, which affects agriculture and ecosystem.

4. Ecosystem impact: Weather changes can change the structure and function of ecosystems and affect the distribution, migration and survival of species. For example, global warming leads to melting glaciers and rising sea levels, affecting marine ecosystems and coastal communities.

5. Energy demand: Climate change will also affect energy demand. In the case of extreme high temperature or severe cold, people tend to use air conditioning and heating equipment, which leads to an increase in energy demand.

6. Economic impact: Weather changes have an important impact on the economy. Bad weather conditions may lead to traffic disruption, damage to facilities and production stagnation. This will have a negative impact on business activities and economic development.
