Please join the discussion: What Effect Do Greenhouse Gases Have on Climate Change?
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.
It is difficult to determine the extent of change that humans cause, but using computer-based models, it has been discovered that rising concentrations of greenhouse gases generally produce an increase in the average temperature of the earth. Rising temperatures may, in turn, produce changes in weather, sea levels, and land use pattern, commonly referred to as "climate change."
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.
In this program, we examine the effects of greenhouse gas and the subsequent climate change in Africa and what can be done to contain them.

ABOUT GREEN AFRICA
One of Africa's biggest challenges is the need to develop environmentally sustainable ways of living for its people. Green Africa is a weekly environmental discussion on AV radio, created to help mobilize a fresh understanding of Africa's responsibilities in the universal ecosystem and generate consensus for right action. The program is organized and represented by a wide range of grassroots organizations and experts on a diverse scientific, social, and economics of green politics and environmental issues. Topics are centered around sustainable management of resources and stewardship of the environment through advocacies on changes in public policies and individual behavior in recognition of humanity, ecosystems, ecology, health, and human rights.
The show is brought to you by Amandla News, Beyond Oil, and African Views (AV).
