However, human activities are now increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural warming caused by the greenhouse effect. During the Industrial Revolution, humans began burning coal, natural gas, and oil to power machines for manufacturing and transportation.
I strongly believe that global warming is a phenomenon caused by human activities, which results in a raise in greenhouse gases in the atmosphere. The scientific panel studying climate change stated that the proof of a warming is clear and the human activity has been the major reason for the change. Global warming is the result of warming of earth and sea due to the increased concentration of greenhouse gases. The main cause of global warming is the human activities which emit greenhouse gas which is known as the greenhouse effect. When sunlight reaches the earth it is absorbed by the earth and warms it.
