Global Warming is the increase of Earth's average surface temperature due to the effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. As a result of global warming, the polar ice caps have been melting, causing a rise in sea level. Carbon dioxide is a greenhouse gas and therefore, an increase in carbon dioxide in the atmosphere leads to greenhouse effect. Acid rain has a severe impact on lakes, streams, wetlands, and other aquatic environments in that it makes these water bodies acidic. Aquatic life is acid-sensitive and would be lost as the pH declines. Nuclear winter is a period of abnormal cold and darkness predicted to follow a nuclear war, caused by a layer of smoke and dust in the atmosphere blocking the sun's rays.
