Over the past 100 years, the earth has warmed by 1oF. The greenhouse effect has been part of the earths workings from the beginning. The greenhouse effect helps sunlight to reach planet earth through gases such as carbon dioxide and methane. The gases also help prevent some of the heat from radiating back into space. If the greenhouse effect did not exist, the earth would not be warm enough for life to form. However, the Industrial Economy has released large amounts of carbon dioxide and, as a result, the earth is becoming warmer at an accelerating rate. As the earth gets warmer, sea levels are also gradually increasing. The Arctic and Antarctic are also getting warmer. In addition to this, heat waves are becoming more prevalent, and droughts and fi res are much more noticeable than they were 100 years ago
