Apart from human factors, what are the causes of climate change?

The cause of climate change may be natural internal process, external stress, or man-made continuous changes in the main components of the atmosphere and the use of land resources. The changes of solar radiation, earth orbit, magmatic activity, atmosphere and deep-sea circulation are the natural causes of global climate change. However, human activities, especially those since the industrial revolution, are important reasons for climate change characterized by global warming.

Causes of climate change

1, environmental conditions. As we all know, our earth is warming slowly at this stage. Some experts believe that this warming is self-regulating by the earth? Basic law? Under the long time scale of tens of thousands or even hundreds of millions of years, it is normal that the climate shows corresponding laws, especially the temperature shows corresponding fluctuations. What is the current situation of our planet? Heating period? .

2. Human activities lead to climate change. This statement has been widely recognized by people and has great political and cultural significance. By analyzing the ancient gases obtained from glaciers, experts found that the concentration of carbon dioxide in our air has increased by nearly 60 times compared with that in ancient times, and carbon dioxide happens to be the core member of greenhouse gases. Therefore, because of our human activities, a large number of greenhouse gases have been produced, which is a major cause of climate change.

Climate change refers to statistically significant changes in climate mean and climate deviation, such as changes in average temperature, annual average precipitation, maximum temperature, minimum temperature and extreme weather events. It is often said that global warming is one of the important manifestations of climate change.

In the long history of earth movement, the climate is always changing, which can be summarized into two categories: natural climate fluctuation and human factors.

The influence of human activities on climate: The important influencing factors of world climate change in the last century are: carbon dioxide concentration change, urbanization, sea surface temperature change and forest destruction.
