Global warming refers to the rise in the average temperature of the atmosphere due to the effect of greenhouse gases. Greenhouse gas is a gas in the atmosphere that is been absorbs and emits it radiation at infrared range. The fundamental process of this act causes the greenhouse effect. The greenhouse effect is a process where atmospheric greenhouse gases are been re-radiated into the atmosphere. The most abundant greenhouse gases in the atmosphere are; •Water vapour

Carbon dioxide
Beside, there are non greenhouse gases that have no effect to the atmosphere and also non-greenhouse gases like carbon monoxide that has indirect radiation effect by elevating the concentration of methane in the atmosphere. One of the major contributors to the green house effect is Cloud. Cloud is a non gas contributor to the green house effect because it also absorbs and emits radiation in the atmosphere. The recent change in the environment is as a result of human activity. These activities are the causes of Global warming; Burning of fossils fuel by industrial increases the effect of the greenhouse gases in the atmosphere. Besides, burning of timber drive from deforestation increases the amount of carbon dioxide in the atmosphere e.t.c. Increase in the concentration of aerosols in the atmosphere. DEFORESTATION: Deforestation refers to the removal of trees from forest whereby the land is converted to a non forest zone. This practice has an effect on the atmosphere by reducing carbon dioxide in the atmosphere. As we all know plant prepare their food through the use of carbon dioxide and water to give out oxygen as a waste product in order to maintain the normal level of oxygen in the atmosphere (photosynthesis). Removal of trees reduces one of the greenhouse gases from the atmosphere which causes global warming. Carbon dioxide can be replenished by the government encouraging a process called afforest ion. Aerosols refer to suspensions of liquid or solid in...
