There are some reasons for global warming. Firstly, global warming is mainly caused by carbon dioxide around the earth. Most climatologists believe that the greenhouse effect is an important cause of global warming. When greenhouse gases such as carbon dioxide and methane cover the earth with a layer, the heat of the sun is trapped inside the layer. Thus the earth begins to get warmer. This is the gradual warming of the air as well as the earth.
