Illustration of the "greenhouse effect". The build-up of certain gases in the Earth's atmosphere traps an increased amount of solar radiation and leads to a gradual warming of the whole planet. The "greenhouse" gases include carbon dioxide,methane,nitrous oxide and chlorofluorocarbons (CFCs). They are generated by a wide variety of human activities,including industry,the burning of fossil fuels,increased agriculture and modern agricultural methods,and deforestation. Global warming is expected to cause massive changes in weather patterns and a rise in sea level (due to the melting of polar ice) that could flood coastal cities and low-lying plains | |
