One cause of global warming

Global warming has many causes in our life. In this paragraph I will write about one causes of global warming which is green house effect.
The greenhouse effect was discovered by Joseph Fourier in 1824. The process of this phenomenon is when the emission of infrared radiation which is on the atmosphere warms plants surface. The name of this phenomenon comes from an incorrect comparing between air inside a greenhouse and the air outside greenhouse. The earth's average surface temperature is about 25°C warmer than without the greenhouse effect. Greenhouse effect may refer to the natural greenhouse effect due to naturally greenhouse gases or other greenhouse effect which resulted from gases emitted as a result of human activities.
