Definition of Global Warming

Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet life able. However, by burning fossil fuels such as coal, gas and oil and clearing forests. Forests are especially important to us because trees, like other green plants, take carbon dioxide from the air when they make their food by the process called photosynthesis. Carbon dioxide and other gases will make atmosphere thicker so the heat will trap it the earth because the Carbon dioxide and other air pollution that is in the atmosphere trapping the sun’s heat and causes the earth to warm up.
