The long-term average weather conditions in a place are called climate.
1. Definition and characteristics
Climate is a description of the long-term (usually 30 years) average weather conditions in a region. Climate includes the average values and variation ranges of temperature, precipitation, wind speed, sunshine hours, etc., which can help people understand the basic weather characteristics of a place, so as to better adapt to and utilize the local environment.
2. Influencing factors
The formation of climate is affected by many factors, including geographical location (such as latitude, topography and ocean), atmospheric circulation, ocean currents, solar radiation, etc., which interact with each other. Function, together determine the climate characteristics of a certain area.
3. Classification and Region
Climate conditions around the world are diverse and can be roughly divided into tropical, subtropical, temperate and boreal climate types; different climate types correspond to different geographical areas, each climate type has its own unique characteristics and impacts. For example, temperate climates usually have four distinct seasons, while tropical climates are hot and rainy all year round.
The impact of climate on humans 1. Ecological and environmental impacts
Climate change has a significant impact on the ecological environment. As temperatures rise, melting glaciers cause sea levels to rise, putting coastal areas at risk of flooding; extreme weather events such as heavy rains, droughts and heat waves occur frequently, causing damage to natural ecosystems and affecting biodiversity.
2. Economic and social impacts
Climate change has a profound impact on global economic and social development; agriculture, fisheries and tourism are directly affected by climate change, and economic output may be affected. ; Uneven resource distribution and population migration caused by climate change may lead to social inequality and conflict.
3. Health and safety impacts
Climate change poses a threat to human health. Extreme weather events may lead to the outbreak and spread of diseases, such as malaria, dengue fever, etc.; high temperature, air pollution, etc. also Increased risk of cardiovascular and respiratory diseases; climate change may trigger political and economic security issues, such as competition for resources and increased international cooperation and geopolitical tensions.
