Causes of climate warming

Causes of climate warming: 1, solar activity; 2. The cloud cover is reduced; 3. Greenhouse gases; 4. Deforestation of virgin forests; 5. Carbon emissions.

With the change of global environment, our climate is getting warmer and warmer. Careful observation shows that winter is not as cold as before. What are the causes of climate warming? The following small series will give you a specific introduction.

Solar activity: Some experts believe that the current climate warming is related to the solar cycle and has little to do with human activities. Russian scientists believe that the warming cycle of Mars is consistent with that of the Earth, and the main reason is the sun.

Decrease of cloud cover: The change of solar activity will change the cloud cover over the earth, amplify the influence of the sun on the earth, and thus affect climate change. They speculate that cosmic rays emitted to the earth can stably ionize part of the atmosphere, making it easy for clouds to form, thus absorbing a lot of solar radiation and lowering the temperature of the earth.

Greenhouse gases: Global warming is related to the greenhouse effect caused by a large number of greenhouse gases emitted by human beings. Greenhouse effect is the main cause of global warming, which is put forward by scientists after investigating the correlation between the increase of carbon dioxide emissions and the rise of temperature in the past 100 years.

Deforestation: Another cause of global warming is wanton deforestation, which reduces the ability to absorb carbon dioxide in the atmosphere.

Carbon emission: Since 1975, the average temperature of the earth's surface has increased by 0.9 degrees Fahrenheit, and global warming caused by the greenhouse effect has become the focus of attention. The academia has always recognized that carbon dioxide produced by the burning of coal, oil and natural gas is the chief culprit of global warming. However, after decades of observation and research, Dr. james hanson from Goddard Institute of Space Studies in the United States put forward a new view that greenhouse gases are mainly carbon dust and other substances, not carbon dioxide.
