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