The climate of our planet is changing, which is occurring at a rapid rate. While some people do not believe in climate change, it is a reality that we have to face. Human activity is responsible for the climate change that the Earth is facing today. Increased emission (排放) of carbon dioxide, and increase in greenhouse gases and pollution are responsible for the changes in the climate today. The change in the weather patterns all over the world is having a bad effect not just on the animals and plants, but also on humans. So, what are the causes of climate change?
Climate change has been taking place for a long time. However, this change was so miniscule that we did not pay attention to it. Now, this change has become fast and the effects are being felt all over. Unfortunately, climate change is irreversible (不可逆的). Some of the causes for climate change are listed below:
Solar change is one reason for climate change. The sun is the major source of energy and an important part of our climate. However, due to solar change, global warming has started.
The way the Earth goes around the sun plays an important role as to how sunlight is distributed over the surface of the Earth. It is due to this revolution that the Earth faces changes in its climate each year and that is why we have different seasons in the year. As volcanoes erupt and pour out lava (岩浆), they also release tiny matter into the atmosphere, which have an effect on the climate of the region.
However, besides all these natural processes that cause natural changes in the climate of the Earth, the biggest artificial influence on the Earth's climate is human activity. Industrialization, rampant deforestation, burning of fossil fuels, and increase in automobiles is responsible for severe and irreversible changes in the climate.
