Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface roughly constant.

 

Human-produced greenhouse gases usually emanate from manufacturing industry to the resort to such energy sources as coal, oil and natural gas. Africa produces less greenhouse gases yet it is at the receiving end of the effects of greenhouse emission from other parts of the world. Continuous desertification and climate change on the continent have been attributed to greenhouse gases. Unfortunately, the producers of the bulk of greenhouse gas many of who happen to be signatories of the Kyoto Convention that limits the amount of greenhouse gas to be produced are yet to adhere to the regulations in the convention.
