What are the risks of climate change?
1, natural disaster. Extreme weather phenomena such as storms, floods, droughts and rainstorms caused by climate change may occur frequently, threatening people's lives and property.
2. Food security. Climate change will affect the growth and yield of crops, lead to food shortage and pose a threat to global food security.
3. Health risks. Climate change will lead to changes in temperature and humidity, increase the risk of cardiovascular, respiratory and infectious diseases, and have a negative impact on human health.
4. Vulnerability of infrastructure and urban planning and construction. Climate change may increase the vulnerability and risk of urban drainage systems, seawalls and other infrastructure.
5. Lack of water resources. Climate change may lead to drought and water shortage, affecting the survival of a large number of people and animals and plants.
6. Loss of biodiversity. Climate change may lead to changes in the earth's ecosystem, resulting in the disappearance of a large number of species, which has a major impact on the ecosystem.
7. Agricultural production. Climate change will affect agricultural production, and long-term drought or flood disasters will lead to crop failure and pose a threat to global food security.
8. Sea level rise. Global warming will lead to melting glaciers and rising sea levels, which will do harm to coastal areas.
9. Extreme weather and climate events. Climate change may lead to an increase in extreme weather and climate events, such as droughts, floods, typhoons and rainstorms, which may have a negative impact on agriculture, water resources and transportation.
10, the increase of disease transmission. Climate change may lead to changes in the spread of different infectious diseases, which will have a negative impact on public health. For example, rising temperature may lead to a sharp increase in the number of pests, thus increasing the spread of infectious diseases.
Factors affecting climate change:
Natural factors include solar radiation, volcanic activity, earth rotation and revolution, etc. Solar radiation is the most important energy source on the earth, and its change will have an impact on the earth's climate. For example, the change of solar activity cycle will lead to the change of temperature and rainfall on the earth.
Volcanic activity will release a lot of gas and particles, which will affect the climate and environment of the earth. Changes in the earth's rotation and revolution will also have an impact on the earth's climate. For example, changes in the earth's orbit will lead to changes in the solar energy received by the earth, thus affecting the earth's climate.
Human factors are also important factors affecting climate change. With the development of industrialization and urbanization, human activities produce a large number of greenhouse gases, such as carbon dioxide, methane and nitrous oxide, which will form a greenhouse effect in the atmosphere.
Causing global warming. In addition, human activities will also lead to deforestation, fossil fuel burning and agricultural activities, which will have a negative impact on climate and environment.
